Description

A method for inputting a mathematical operator on a keypad and a device therefor{.}

[0001] The present invention relates to an alphabetic input device and method thereof in a keypad, and more particularly, to an alphabetic input device and method in a keypad having a small number of keys such as a telephone keyboard.

With the development of mobile communication, a function for transmitting and receiving digital information, such as text, has been added to a portable terminal mainly for voice calls. Accordingly, in the beginning, a keypad provided in a portable terminal for the purpose of inputting a phone number also includes a means for inputting characters. However, since the size of a keypad used as an input means of a portable terminal becomes smaller and smaller, the number of buttons included in the keypad has its limit. Meanwhile, the alphabet of each language greatly exceeds the number of 12 keys included in the keypad. Therefore, in order to input one alphabet using a telephone keypad, one or two or more buttons on the keypad must be combined to express the alphabet.

[Detailed description of the invention]

A summary of the invention presented in the applicant's prior application (application number 10-2000-0031879 and PCT/KR00/00601) is as follows.

First, according to the "Partial All Selection Method", a predetermined number of grids are variously configured as illustrated in FIG. 1 in a form corresponding to the arrangement of all buttons in the keypad to each button on the keypad, and alphabets are arranged on the grids, The first button on which the alphabet to be input (hereinafter, abbreviated as "target alphabet") is arranged and the second button on the keypad are pressed in a combination corresponding to the arrangement position of the alphabet in the grids of the first button to input the desired alphabet. do. For example, in Fig. 1-1 of Fig. 1, "A" = [2] + [1] is entered.

Among the grids of buttons, some grids including a reference grid in which the first and second buttons are the same, and some grids are used, but the convenience of the combination of the first button and the second button is high. Using the ordered grid first was the core of the partial-total selection method. In this way, the core of the partial selection method lies in the reference grid, and the keypad that can utilize the concept of the reference grid was named "reference keypad".

Next, the reference repetitive selection method is the number of times the button is pressed in the order of the alphabet at the reference grid position to the reference grid (the order of convenience of button combinations in the partial selection method) on the reference keypad configured to apply the partial selection method. It was a way to ensure that the alphabet was selected according to. The reference repetitive selection method is to apply the repetitive selection method in the reference keypad. The dedicated reference keypad is named "simple keypad", and for convenience, the repetitive selection method is applied in the simple keypad as it is used in the past. I named it the simple repetitive selection method.

And there were "control processing method", and there were "subscript control processing method" and "subsequent control processing method". The subscript control processing method was to allow the input of the modified alphabet by combining the subscript control and the basic alphabet when inputting a modified alphabet consisting of a subscript and a basic alphabet. In the subsequent control processing method, a group of alphabets assigned to a button is set as the relationship between the representative alphabet and the subsequent alphabet, and when entering the subsequent alphabet, the subsequent alphabet can be input by combining the representative alphabet and the subordinate rankings attached to the representative alphabet. Was to be. For example, in Fig. 4-1, you can enter "ㅋ = ㄱ+[*]".

Subscript control processing and subsequent alphabet control processing are essentially similar, and the subsequent control processing is considered to be more common. This is because, in the case of subscript control processing, it can be seen that the modified alphabet is attached to the basic alphabet in a certain order in a specific alphabet group. However, in the case of subscript control processing, since the modified alphabet can be decomposed into subscript and basic alphabet, it is the case that the alphabet group has a strong relationship in its shape, and the subsequent control has a strong relationship in its order or pronunciation. to be.

The advantage of applying the control processing method is that the layout of the keypad can be simplified by not displaying the subsequent alphabet (or modified alphabet) on the keypad through the relationship between the basic alphabet and the subsequent alphabet (or modified alphabet). It was possible to enter the alphabet without ambiguity through control processing. The simplified keypad by omitting the subsequent alphabet was referred to as "subsequent keypad", and the simplified keypad by omitting the modified alphabet was referred to as "simple keypad", and both were collectively referred to as "simplified keypad". The keypad in which all subsequent alphabets (or modified alphabets) were displayed was referred to as "full display pad" compared to the simplified keypad.

It is said that the entire display pad can also input the subsequent alphabet (or transformed alphabet) through the control processing method, and on the contrary, a user who remembers the layout of the entire display pad in the simplified keypad can use the input method in the full display pad. . One of the features of the previous application was that the simplified keypad can be expanded to configure the entire display pad, and the compatibility of the entire display pad to input the subsequent alphabet through the control processing method according to the user's convenience was one of the characteristics of the previous application.

One of the effects of applying the control processing method is that, in addition to the effect of removing ambiguity, as shown in the previous application, the subsequent alphabet is not displayed on the keypad through the relationship between the representative alphabet and the subsequent alphabet, but is "hidden". The keypad can be simplified. This is called "hidden control processing method" for convenience. However, as mentioned in the previous application, the subsequent alphabet can also be input through the control processing method in the entire display pad in which the subsequent alphabet (or modified alphabet) is displayed on the keypad. For convenience, this is called "non-hidden control processing method".

The present invention proposes improvements in line with the extension of the applicant's earlier application (application number 10-2000-0031879 and PCT/KR00/00601). In addition, a method for entering common phrases with a small number of strokes by the shortened input method is proposed, and a parallel input method that combines the shortened input method and the full input method is applied so that all the desired alphabets can be entered, while reducing the number of input strokes. We present a method to improve the convenience of input. In addition, a method for inputting various symbols on the previously suggested keypad is presented, and a method for using a movement button that is not frequently used in alphabet input mode among movement buttons as a control button is presented.

It will be described in "Specific contents for carrying out the invention".

Through the present invention, it is possible to efficiently input alphabets on a keypad. A concise keypad can be maintained by allowing various symbols to be input using a hidden control processing method.

In addition, a simple code can be generated by using the correspondence between alphabets and numbers arranged on the keypad, and a shortened input method can be realized through this simple code. You can enter all of them.

If there is a relay server that interprets the simple code, the user inputs the simple code and stores the simple code and the phrase corresponding to the simple code on the tertiary server side, even if the tertiary server requires a phrase other than the simple code. Even if it is not done, it is possible for the relay server to interpret the simple code input from the user by the relay server and deliver the phrase corresponding to the simple code to the tertiary server side.

First, the contents of the previous application for each language are supplemented as follows. Among the contents mentioned in one language below, it is obvious that the contents applicable to other languages can be applied to other languages even if they are not specifically mentioned in other languages.

[Example]

1. Common supplements

1.1 Prior application and the scope of use of the keypad in the present invention

It is apparent that the keypad proposed in the previous application and the present invention can be applied to all fields in the form of a telephone keyboard, such as a numeric keypad of a mobile terminal or a standard keypad, or a keypad or door lock configured in software on a screen. In addition, although the numeric keypad provided in the standard keyboard differs in the arrangement of the keypad and the numeric buttons proposed in the previous application and the present invention, it is apparent that the arrangement on the keypad buttons in the prior application and the present invention can also be applied to a keypad provided in the keyboard. For example, in the previous application and in the present invention, the alphabet arranged on the [1] button is placed on the [1] button of the numeric keypad provided on the keyboard, and then arranged in the same manner to input the alphabet, use simple codes, and memorize various codes. It can be used as a dragon.

1.2 Setting of consecutive hitting delay time and hitting delay time

In languages in which consonants and vowels appear alternately, such as Korean and Hindi, in applying the method of assigning a pair of representative consonants and representative vowels to each button, and selecting one consonant vowel as two strokes, a certain delay time ( For example, if the algorithm is implemented to recognize two strokes of the same button input within an interval of 0.1 second) as a collection, it is possible to implement efficiently while reducing the feeling of rejection to the user. This delay time should be determined in consideration of the time interval in which the same button is pressed continuously for a certain period of time. For convenience, this delay time is referred to as "battery stroke delay time". In addition, it can be implemented so that two strokes of the same button input more than a certain delay time (for example, 1 second) are primarily recognized as two consonants. For convenience, this delay time is referred to as "eating delay time". This can also be applied when the same button is pressed 3 or more strokes.

For example, in Fig. 4-1 or Fig. 4-2, if [1] + [1] is input with a delay time of 0.08 seconds, it is primarily recognized as the vowel "ㅗ", and if the 1.1 second delay time is If it is entered with, it is primarily recognized as two consonants ("ㄱ","ㄱ"). If it is input with a time delay of 0.5 seconds, it is possible to determine whether one vowel or two consonants have been input through the appearance structure of consonants and vowels in the language. In addition, even when input with a delay time of 0.08 seconds or 1.1 seconds, it is possible to finally determine whether one vowel has been input or two consonants have been input through the appearance structure of consonants and vowels in the language.

Previously, only one stroke was set at a certain time interval (for example, 1 second), and if the same button was continuously input within that time, it was recognized as two strokes in a row, and if two strokes of the same button were pressed after the corresponding time was delayed, each stroke was recognized as one stroke. The difference is the difference between the standard time delay value (e.g. 0.1 second) judged as two consecutive strokes and the time delay value (e.g. 1 second) judged as one stroke each.

In general, it can be seen that the repetitive selection method is excellent in terms of input convenience among the partial and repetitive selection methods of the previous application. Therefore, this means that while taking advantage of the repetitive selection method (simplicity and convenience of input rules), ambiguity can be avoided significantly by using the structure of a specific language in which consonants and vowels alternately appear. By setting the delay time differently and allowing the user to designate it, there is an advantage of simplifying the implementation of the algorithm.

1.3 Chain type control processing method

In the earlier application, the subscript control processing method is essentially the same as the subsequent control processing method, and the subsequent control processing method is said to be a more general method. In other words, in the Korean example of the previous application, the relationship between ㄱ, ㅋ, and ㄲ was explained as the relationship between the representative alphabet and the modified alphabet, and ㅋ = ㄱ+{Abbreviated}, ㄲ = ㄱ+{Kyeongeum}, but ㄱ(representative alphabet) This is because the result is the same even if the relationship between the representative alphabet and the subsequent alphabet, such as, ㅋ(2nd), ㄲ(3rd).

In the case of Japanese in Fig. 2-1, an example of input by the subsequent control processing method will be shown again as follows. Select あ as one stroke on the [1] button in relation to the representative alphabet and subsequent alphabets, such as あ(representative alphabet), い(2nd), う(3rd), え(4th), and お(5th) (あ=[1 ]), and put the 2nd, 3rd, 4th, and 5th controls on a control button (ex. [*]) and repeatedly select according to the number of times the button is pressed, and enter the subsequent alphabet with a combination of the representative alphabet and the subsequent alphabet. I can. For convenience, the selected state of the control is indicated in braces, for example, when applying input after control, あ=[1], い = あ+{2nd}=[1]+[*], う = あ+{3rd} =[1]+[*]+[*], え = あ+{4th}=[1]+[*]+[*]+[*], お = あ+{5th}=[1]+[ *]+[*]+[*]+[*]

Here again, make the relationship between the representative alphabet and the subsequent alphabet, such as あ (representative alphabet), い (2nd), う (3rd), え (4th), and お (5th), but place the follow-up control on the control button and repeat selection method. Rather than selecting the "follow" or "next" control by pressing a specific control button (e.g. [*]) once, it is possible to select the "subsequent" or "next" control, and when entering the second succeeding alphabet (e.g. い), the representative alphabet and the corresponding alphabet are selected. Enter a combination of "next contract" (that is, い = あ+{next}= あ+[*]), and when entering the 3rd succeeding character え, the preceding character (the 2nd succeeding character) is replaced with a new character for the 3rd succeeding character. It is regarded as the representative alphabet (second representative alphabet) and can be entered in combination with the second successor alphabet and "Next Control". That is, う = い+{next}=[1]+[*]+[*]. Similarly, when entering the 4th successor alphabet え, the preceding character (the 3rd successor character) う is regarded as the new representative alphabet for the 4th successor alphabet (the 3rd representative character), and when entering え, え = う+{next}= You can enter [1]+[*]+[*]+[*]. The same is true for the 5th successor alphabet.

This result is the same result as placing the sub-priority control (2nd, 3rd, 4th, 5th,...) on the control button and selecting it by the repetitive selection method, and entering a combination of the representative alphabet and the sub-priority control. . Here, if the first representative alphabet あ can be selected without ambiguity, it is easy to see that the second successor alphabet い can be entered without ambiguity, and the same is true for the remaining subsequent characters. That is, え = い+{next}=[1]+[*]+[*]. い could be entered without ambiguity, and い is also a form that is combined with "Daum Control", resulting in a subsequent alphabet without ambiguity. You can enter え.

Thus, in the relationship between the representative alphabet and the subsequent alphabet, it is assumed that the control button does not have a subordinate priority control, but only one "next" control, and when entering the subsequent alphabet, the preceding alphabet is regarded as a new representative alphabet, and this preceding alphabet and "next" The method of inputting by combining controls is called "chain-type follow-up control processing method" for convenience. In the previous application, it was said that the user only needs to recognize that a specific button is a subsequent control button, even if the sub-priority control is not displayed on the subsequent control button. However, the advantage of this chain-type subsequent control processing method is that the "next control" is displayed on the control button. Even if it is displayed, the display can be simplified. In the present invention, the results of the "follow-up control processing method" and "chain-type follow-up control processing method" described in the previous application are the same, so they are used interchangeably.

1.4 How to handle skip control

을 입력함에 있어서 이를 .. 과 e 를 각각 조합하여 입력할 수 있음을 보였다. 혹은 e 를 기본알파벳으로 두고 이와 모양 혹은 순위 등에서 연관성을 가지고 있는 나머지 부속된 알파벳을 후속알파벳으로 두어, 부속순위와 기본알파벳의 조합으로 입력할 수도 있었다(예를 들어 e(기본알파벳),

또한 이렇게 알파벳(즉 특정 숫자버튼)과 조합하여야만 의미를 가질 수 있는 컨트롤들이 배치되는 컨트롤 버튼은 반복적으로 사용하여도 모호성 없이 변형알파벳 혹은 후속알파벳을 입력할 수 있었다.A modified alphabet consisting of ".. + e" in the subscript control processing method

It was shown that when inputting, it can be input by combining each of .. and e. Alternatively, it was possible to enter e as the basic alphabet, and the remaining subsidiary alphabets that are related in shape or rank as the successor alphabet, and entered as a combination of the subsidiary rank and the basic alphabet (e.g. e (basic alphabet),

In addition, the control button, in which controls that can have meaning only when combined with an alphabet (that is, a specific number button) are used repeatedly, was able to input a modified alphabet or a subsequent alphabet without ambiguity.

의 변형알파벳이 사용되며, 변형알파벳에 사용된 윗점의 종류는 5가지(/,^,｀,..,s) 이다. 첨자컨트롤의 선택순서를 /,^,｀,..,s 로 하였을 경우, ^a=a+[*]+[*] 로 입력하여야 한다. 그러나, 프랑스어에서 알파벳 a 에는 첨자 "｀"와 "^"의 두가지 밖에 결합할 수 없으므로, 첨자"/" 가 붙을 수 없고, 이를 건너뛰어 결합이 가능한 첨자"^"이 선택되도록 하면, ^a=a+[*] 로 입력할 수 있다. 이를 편의상 "건너뛰기 컨트롤처리방법"이라 부른다. 즉 이는 a(기본알파멧),｀a(2nd),＾a(3rd) 와 같이 후속알파벳의 부속순위를 두고 컨트롤처리방법으로 후속알파벳(혹은 변형알파벳)을 입력하는 것과 같다.11 in French for Roman characters

The transformed alphabet of is used, and the types of upper points used in the transformed alphabet are 5 types (/,^,｀,..,s). If the subscript control selection order is /,^,｀,..,s, you must enter ^a=a+[*]+[*]. However, in French, since only two subscripts "｀" and "^" can be combined in the alphabet a, the subscript "/" cannot be added, and if the subscript "^" that can be combined is selected by skipping this, ^a= You can enter a+[*]. This is called "Skip Control Processing Method" for convenience. In other words, this is the same as entering the following alphabet (or modified alphabet) as a control processing method by placing a subordinate priority of the subsequent alphabet such as a (basic alphabet), ｀a (2nd), ＾a (3rd).

Likewise, in Japanese, only つ among the alphabets of the あ, や and た lines is the line with the long sound, and the line with the sound tone is only the alphabet of the か line, さ line, た line, and ほ line, and the semitones are only the alphabets of the か line, さ line, た line, and ほ line. It only exists in the alphabet of line ほ. As a result, it can be seen that in the alphabet つ there are two variants of the long sound and the sound sound, and in the alphabet of the ほ line, the two variants of the sound sound and the semi-voiced sound exist. Therefore, it can be made possible by pressing the subscript control button once when inputting the modified alphabets of the rest of the alphabet except for the 6 alphabets in which the two modified alphabets exist. For example, if you put the control button as the [*] button and apply the input after control, you can do something like あ = あ+[*], か = か+[*]. In the case of 6 alphabets with two variant letters, the control can be selected in the order of the frequency of use of the variant letters when inputting variant letters. For example, when the control button is set as the [*] button and the input after control is applied, つ = つ+[*], づ = つ+[*]+[*], ぼ = ほ+[ *], ぽ = ほ+[*]+[*]. That is, in control selection, controls that cannot be combined with the basic alphabet do not take effect. For example, even if が = か+[*], [*] can be treated as selecting a sound control, not a long sound control, because the basic alphabet か that is combined with the control does not have a long sound, so the long sound control is not selected. This is because it is assumed to be skipped and the sound tone control selected.

The advantage of strictly applying the control selection is that it enables input of alphabets that are not actually used. For example, there is no alphabet with the subscript ".." in the French alphabet b, but such an alphabet can be input, and there is no alphabet with a dot in the Japanese alphabet あ, but such an alphabet can also be entered. It can be done.

Even if the control is selected by the repeated selection method, if the representative alphabet displayed on the keyboard can be entered without ambiguity when input through the control processing (for example, even if there is only one or more representative characters displayed on the keyboard, there is no ambiguity such as the partial selection method. Is applied), the remaining subsequent characters can also be entered without ambiguity. This is because the ambiguity is removed through the control process, because the control does not represent a specific alphabet by itself and must be combined with other alphabets.

1.5 Input by control processing method of numbers and English alphabet

As suggested in the previous application, it was explained that the native language alphabets can be placed in the "order close to the standard grid", followed by numbers and English alphabets. When applying the standard repetition selection method, it is also possible to place them in the order close to the standard grid. Explained that alphabets and numbers can be selected. Similarly, in applying the subsequent control processing method, not only the native language alphabet belonging to a specific button, but also numbers and English alphabets (in case of non-Roman language) can be entered through the subsequent control processing method.

Numerals or English alphabets can be placed as a subsequent alphabet following the national language alphabet. For convenience, in Japanese, for example, あ(representative alphabet), い(2nd), う(3rd), え(4th), お(5th), 1(6th), .(7th), q(8th), You can put it like z(9th). Also, if there are buttons available to control numbers or English alphabets, control buttons for あ(representative alphabet), い(2nd), う(3rd), え(4th), お(5th) can be selected as an arbitrary button ( For example, put it as [*] button), and another button (for example, [#] button) as a button for numbers or English alphabet あ(representative alphabet), 1(2nd), .(3rd), q( 4th), z(5th) can be used to input numbers or English alphabets. For example, 1 = あ+[#]=[1]+[#],.= あ+[#]+[#]=[1]+[#]+[#], q = あ+[#] +[#]+[#] = [1]+[#]+[#]+[#] If a control button is available, it is also possible to have separate control buttons for numeric input and control buttons for English alphabets.

This can be applied to other languages, and can also be applied to input of various symbols to be described later.

1.6 Grouping according to English alphabet pronunciation

In configuring the keypad for each language in the previous application, in consideration of the application of the control processing method and the use for memorization, alphabets were grouped into similar pronunciation groups and assigned to each number button. In the case of English, a method in which each group is assigned to each number button by grouping 3 or 4 alphabets according to the current alphabetical order is widely used, but it is possible to group and assign to each number button in consideration of the similarity of pronunciation. The following are some examples of English consonants grouped into 9 groups according to the similarity of pronunciation.

BP/CSX/DT/FVH/GKQ/JZ/LR/MN/WY

BPV/CSX/DT/FH/GKQ/JZ/LR/MW/NY

An example of grouping English consonants into 8 groups is as follows.

BFPV/CGKQ/SX/DT/JZ/LR/MWH/NY

BFPV/CGKQ/SX/DT/JZ/LR/MN/WYH

In addition to the above example, many variations are possible. Five vowels can be put into groups grouped by two. This can be convenient when applying the shortened input method using a simple code that will be described later. In the case of a non-English-speaking language, when assigning the grouped English alphabet to each button, it may be assigned in consideration of similarity with the pronunciation group of the native language. For example, in the case of Korean, groups G, K, and Q are assigned to buttons with the alphabet "a" with similar pronunciation. In the case of Japanese, groups G, K, and Q are assigned to buttons with a similar pronunciation "か". Therefore, even in grouping of English alphabets, grouping can be performed in consideration of the native language alphabet grouping of each language.

2. Supplements for each language

Hereinafter, the content of the previous application for each language will be supplemented and the developed matters will be described as follows. It is obvious that, among the contents described in the supplement for each language, if the contents described in one language can be applied to other languages, it can be applied to other languages without specially pointing out this.

2.1 English

Just as in the previous application, it is possible to input the subsequent alphabet through the control processing method on the entire display pad, even in the case of English, it is possible to display alphabets other than the representative alphabet on the keyboard and input them through control processing. In the case of English, subsequent controls (2nd, 3rd) can be placed on the same control button (for example, the [#] button), or can be placed separately on different buttons (for example, [*], [ #] button). In the case of English, when ABC is placed on one button, if A is the representative alphabet, B and C are entered through subsequent control processing, and if B is the representative alphabet, A and C are each subsequent control processing. It is input through. As mentioned in the previous application, the ranking of the representative alphabet and the subsequent alphabet may be determined in consideration of the frequency of use, etc.

For example, in groups A, B, and C, if A is the representative alphabet, 2nd, 3rd control is placed on the [*] button, and input is applied after control, B = A+{2nd} = [2]+[*] , C = A+{3rd} = [2]+[*]+[*]. If B is the representative alphabet, 2nd and 3rd controls are placed on the [*] button and [#] button respectively, and the input is applied after the control, A = B+{2nd} = [2]+[*], C = B+{3rd} = [2]+[#]. 1-2 is a case in which the central alphabet among the alphabets of each group is used as the representative alphabet, and the subsequent alphabets are arranged on the left and right, respectively, in order to further facilitate the identification of the alphabet. D = E+{2nd} = [3]+[*].

In addition, when four letters P, Q, R, S are assigned to the [7] button, and four letters W, X, Y, and Z are assigned to the [9] button, as pointed out in the Korean example of the previous application In addition, one of the four alphabets can be placed on a grid forming a top-bottom contiguous combination to apply a partial-to-whole selection method. See Fig. 1-3.

2.2 Japanese

In the case of Japanese in the earlier application, alphabets are grouped based on 50 phonetic levels, and the alphabet in the あ stage (あ, か, さ, ...) is used as the representative alphabet, and the remaining alphabets are used as the subsequent alphabets for subsequent control processing. It was stated in the earlier application. In applying the subordinate ranking of the subsequent alphabet suggested in the previous application, the 50-note chart may be simply applied as shown in the following table, almost similar to the method 3 of the previous application. This can give users a sense of familiarity with the simplicity of the subordinate rankings. As in the previous application, ん can be treated as being attached to any representative alphabet. In addition, it can be regarded as appended with a 50-phonetic alphabet (for example, い, う, え) or as appended with ん in the empty part of the や line or the わ line.

In the earlier application, for convenience, the alphabet in the first column, which is considered to be the most representative in the case of Japanese, was used as the representative alphabet.Also, the alphabet in any column may be used as the representative alphabet, and an arbitrary alphabet in each group is used as the representative alphabet. You may. Also, in assigning the alphabet of each row to each button as a group, as mentioned in the previous application, the row of buttons on the keypad is standard ([1],[2],[3],[4],...) It can be assigned as, or columns can be assigned as criteria ([3],[6],[9],[2],[5],...). Likewise, it is not possible to allocate based on row or column, but can be randomly assigned.

In addition, in the Japanese example of the earlier application, if "N" is placed at the standard grid position of the [0] button, and 2nd, 3rd, 4th, 5th controls are placed on the [*] button and the [#] button, respectively, press the [0] button. In order to use it as a control button for inputting long/voiced/half voiced sounds, it was assumed that “n” was assigned to a random number button instead of the [0] button. However, in this case, you may place "n" at the position of the reference grid of the [0] button, additionally arrange long/voiced/half tone controls in an order close to the standard grid, and apply the repeat selection method to control selection. This is because "ん" does not appear consecutively in one word. See Figure 2-1. In this way, an alphabet that does not appear in succession is selected for one stroke of the button on which the corresponding alphabet is arranged, and other controls for two strokes, three strokes, ... can be applied to all other languages as well. This property is also used in the method using the vowel elements of Korean, which will be described later.

2-3 Arabic

There are 28 consonants in Arabic. In the earlier application, Arabic consonants having the meaning of numbers are grouped as follows and assigned on the keypad buttons, and each alphabet is placed at the position of the reference grid with the alphabet having the smallest number as the representative alphabet of each group, and the remaining alphabets A plan has been proposed to arrange on the keypad in the order (explained in the previous application) from the alphabet having the meaning of small numbers to the standard grid. In addition, in the earlier application, a method of inputting alphabets by control processing in the case of Japanese, Roman language, Korean, Indian, and Arabic languages has been suggested. In the case of Arabic, a method of handling subscript control by considering vowels that are rarely used as subscripts has been suggested.

Here, I would like to present a method of controlling consonants in Arabic (subsequent control processing). The following is an example of grouping Arabic consonants and assigning them to each button in the previous application.

[1] The alphabet having the meaning of 1 among the alphabets having the meanings of 1, 10, and 100 assigned to the button is displayed on the keypad as the representative alphabet, and the remaining alphabets having the meanings of 10 and 100 can be subsequently controlled. As for the control button, any button can be used as in the previous application. If a follow-up control buttons using the [*] button, and place the 2 ^nd, 3 ^rd control, the average input strokes in the input consonant is Tagawa 2. Since only one alphabet is arranged per button, when selecting the alphabet displayed on the button, it is not necessary to select the entire partial selection method. Since the arrangement of the alphabet is conceptual, the alphabet may not be arranged on the keypad as described below.

Again, as in the case of Japanese in the previous application, the subsequent control can be separated by a different button. For example, if assigned to 3 ^rd control distributed to the [#] button, the average input-bats and is about 1.7 Others ((1 + 2 + 2) / 3) it can be entered without ambiguity, as suggested by the 28 consonants in the earlier application There will be.

In this application, an example in which an alphabet with a small number of meanings can be selected as the representative alphabet of each group regardless of the frequency of use of the alphabet of each unit, and an alphabet with a small number of meanings can be selected first in the alphabets of the remaining units. .

In consideration of a fact that the Arab left horizontal writing from the right, that is assigned a 2 ^nd, 3 ^rd, 4 ^th control the [#] button, it is also possible to place the 3 ^rd, 4 ^th control the [*] button .

This means that in Arabic, it is possible to enter the mainly used consonants at an average of about 1.7 strokes without ambiguity.Also, since Arabs know the meaning of the numbers in their native language alphabet, they dare to enter the alphabet on the keypad (in the example, 1 There is a very great advantage of being able to enter an alphabet without displaying the unit alphabet (ie, the representative alphabet). In other words, when applying the method in this application through a keypad displaying only numbers, which unit of the representative alphabet is the alphabet, the control button is the control button for which unit of the alphabet, and the subsequent control uses one control button. If you do, you can enter most of the alphabets (Arabic consonants) needed in real life if you are familiar with the rules such as how to select each subsequent control and whether to pre-enter the control.

As pointed out in the previous application, vowels can also be controlled. When both [#] and [*] are used for consonant control processing, the alphabet having a meaning of 1000 as in the Japanese of the previous application is displayed on the [0] button. Instead of placing it, it is possible to control by placing it on the [1] button, designating the [0] button as a control button for vowel processing, and selecting a subscripted vowel (vowel control, subscript control) by repetitive selection method. Similarly, the vowel control (subscript type vowel) is selected according to the number of times the button is pressed in the order of frequency of use. If only one [*] is used as the subsequent control button for consonants, [#] can be used as the control button for vowels, or both [#] and [0] can be used.

In the examples of FIGS. 3-1 and 3-2, alphabets having meanings 1 to 9 (one unit alphabet) are used as the representative alphabet of each group, but the most frequently used alphabet in each group may be used as the representative alphabet. . And in order to reduce confusion, the alphabet of any unit among 1 unit alphabet (alphabet meaning 1 to 9), 10 unit alphabet (alphabet meaning 10 to 90), and 100 unit alphabet (alphabet meaning 100 to 900) is used. It can also be done in a representative alphabet.

Likewise, the alphabet selected by the subsequent control can also be used for each unit according to the frequency of use. For example, 100 units of the alphabet is much the most frequent use, to represent the alphabet, and then the surface is one unit of the alphabet in many frequently used, to enter a combination of the 2 ^nd control (i.e. in this case one unit control), and the representative alphabetic to make, 3 ^rd control unit 10 to the alphabet and to input a combination (that is, the control unit 10) and representing the alphabet.

In the previous application, it was said that it is possible to input the subsequent alphabet through the control processing method on the entire display pad, so it is possible to input consonants by the subsequent control processing method on the keypad of the previous application as well as the subscript control processing method for vowels. Do. In the 3*4 keypad, if the subscript control button for vowels is the [0] button, it is possible to distribute the control button for consonant input to the [*] button and the [#] button.

2.4 Korean

2.4.1 Separation of aspirated control and horn control

In the example diagram of the previous application, as shown in Fig. 4-1, the aspirated control is assigned to the [*] button and placed at the position of the reference grid, and the horn control is then placed on the grid close to the reference grid, thereby controlling the aspirated sound on one stroke of the control button. The horn control can be selected for 2 strokes. However, when an extended vowel (two vowels) is input, a time delay is naturally given between the vowel and the vowel, so even if the extended vowel is not input through the control processing method, there is virtually no ambiguity. Therefore, in this case, as in the Japanese example of the previous application, the horn control can be additionally assigned to the [#] button and placed at the position of the reference grid so that the horn control can be selected for one stroke of the [#] button. See Fig. 4-2. In this case, when inputting the control first, ㅋ = {aspirated sound}+ㄱ =[*]+ㄱ, ㄲ = {hard sound}+ㄱ =[#]+ㄱ.

2.4.2 Basic vowel control processing

In addition, in the method of using the pair of consonants and vowels in the applicant's first application (10-2000-0025183), "As in the case of Japanese, the following control button is set to [#] and [#] is pre-input (or post-input is also possible). ), and you can also input basic vowels by entering the number buttons." This means that by placing the basic vowel control as shown in Fig. 4-3 and inputting the basic vowel through the control processing method, it is possible to input without any ambiguity. As pointed out in the previous application, the basic vowel displayed on the keypad can also be input by the control process as in the case of Japanese (input by the control process of the subsequent alphabet in the entire display pad).

In this case, the convenience of input is lower than that of repeatedly selecting the basic vowel with the corresponding button 2 strokes, but ambiguity can be completely removed. Since basic vowels are frequently used, it is of course necessary to select "Basic Vowel Control" for basic vowel input with one control button. 4-3 is a diagram in which "Basic Vowel Control" is added for controlling basic vowels from the drawing presented in the previous application. Basic vowel control is selected for 1 control button stroke, and extended vowel control is selected for control button 2 strokes. In the example of Fig. 4-3, if the input after control is applied, ㅏ = [3]+[#], ㅐ = [3]+[#]+[#], ㅓ = [4]+[#], ㅔ = It becomes like [4]+[#]+[#]. The same applies to the rest of the vowels and extended vowels, and can be applied to the similar extended vowel as ㅗ = [1]+[#], ㅚ = [1]+[#]+[#].

This is because the relationship between the representative consonant and the basic vowel is insufficient, so it can be seen that the basic vowel is displayed on the keypad and the basic vowel is input by a non-hidden control processing method.

2.4.3 Common use of aspirated control and extended vowel control

As in the Thai example of the earlier application, one subsequent control button can be used commonly for subsequent consonants or subsequent vowels. For example, the aspirated control and the expanded vowel control are placed on the same grid of the same control button. As described in the previous application, if the control button for the subsequent consonant processing and the control button for the subsequent vowel processing are separated, the pre-input or post-input of each control can be applied differently.

2.4.4 Program Implementation

4-4 is only an example of a flowchart for implementation, and more efficient programming is possible. For example, if the consonant part of the support comes from FIG. 4-4, it is possible to implement a little more efficiently by checking whether it is a consonant that can form a double support.

The example of Korean presented in the earlier application can be applied to other languages with similar characteristics (structures in which consonants and vowels alternately appear). In the case of other languages, it is sufficient to reflect the characteristics of the character expression of other languages.

In the Korean example, the first 3 strokes (input 1,2,3) from "word start" can always be determined as the consonant and vowel of the first syllable (letter). Of course, this does not apply when a syllable consisting of "hat + letter" appears first in Hindi. Next, input 4 can be the end of the first syllable (character) or the initial of the second syllable (letter), so it must be determined. In the flow chart presented in the previous application, all efficient detailed procedures could not be displayed due to the size of the paper, but it was determined whether input 4 was the same as the previous input (input 3), and if they were the same, inputs 4 and 5 could not form a double vowel. It can be determined in advance. This is because inputs 2 and 3 have been confirmed as vowels, but in order for inputs 4 and 5 to form a double vowel as a vowel, they must not be the same vowel. If the input 4 is not the same as the previous input, it is compared with the next input (input 5) as shown in the flowchart, and the next procedure can be performed.

If input 5 is the same as the previous input, it is checked whether the double vowel can be achieved as in the flow chart and proceeds to the next procedure. The following is the case where the double vowels are not formed. If input 5 is not the same as the previous input, input 4 can be confirmed as the base of the first syllable (character), and input 5 may be the double base of the first syllable (letter) or the initial vowel of the second syllable (letter). , In this step, it is checked whether inputs 4 and 5 can form a double support, and if the double support cannot be achieved, input 5 can be determined in advance as the initial vocal of the second syllable (character). In the case of Korean, not all 14 combinations of plain and aspirated sounds (14*14=196) are possible, but only 11 of ㄶ, ㅄ, ㄺ, ㄻ, ㅀ, ㄵ, ㄼ, ㄳ, ㄾ, ㄿ, ㄽ are possible. Because. One syllable (letter) is confirmed, and input 5 is input 1, and the process starts again from the beginning. If input 5 is the same as input 4 and cannot form a double vowel with inputs 2 and 3, input 4 may be determined as the end of the first syllable (character) and input 5 as the initial vowel of the second syllable (character). Although not expressed in terms of space constraints on the flowchart, it is a matter that can be considered of course in programming the invention of the earlier application.

If a double vowel can be achieved, it can proceed as shown in the flowchart. And in all other cases where ambiguity occurs, the word (or syllable (letter)) where ambiguity occurs, as shown in the input example and flow chart of the previous application, ends with a ending (finality) on one side and a ending on the other. If it ends without a word (for example, "Gang and <=> Gnago"), accept the next input ("input x" for convenience) and check whether it is "word ending". If it is a word ending, the input x is replaced with the last syllable (letter). It can be finalized (i.e., "go + input x" in the example).

2.4.5 Basic consonant combination treatment of hard sound

For all Korean keypads mentioned in the applicant's earlier application, it is possible to treat hard sounds (double consonants) as a combination of basic consonants, but for convenience, it will be described with reference to FIG. 4-1.

In addition, the case where the hard sound (double consonant) is allowed to be input as a combination of two plain sounds may proceed similarly to the case where input 4 and input 5 are not the same. However, if this is allowed, the convenience of input increases. However, if the first syllable ends as a vowel without a finality and the second syllable is a hard sound, ambiguity may occur, such as "Ocdugi <=> Ottogi". "C" in "Dougi" cannot be entered in the editor of the KIPO or finality, so it is indicated as such for convenience). In addition, even if the first syllable ends with a ending, the first syllable of the second syllable is a hard sound, and even if the ending of the first syllable and the first syllable of the second syllable are the same (for example, the vowel of the first syllable and the “first syllable” The final vowel + the first consonant of the second syllable (c+c in the example)" is recognized as a vowel and may be a double vowel (in the example, "ㅗ+ㄷㄷ"="ㅗ+[3]+[3]" is a double vowel. Only if it can be achieved). Therefore, due to the nature of the invention of the previous application, since the characteristic of removing ambiguity when inputting a horn sound by controlling the sound sound cannot be utilized, more ambiguity may occur than the case of inputting the sound sound by controlling the sound sound.

In the case of "Octogi <=> Ottogi", this can be avoided through a time delay or a classification input (a means to confirm a syllable such as a right arrow). The same is true of "Octogi <=> Wadugi". However, in the case of the latter case, the case of forming a double vowel in Korean (two combinations excluding the case of three basic vowels) is always in eight cases: ㅔ, ㅢ, ㅘ, ㅚ, ㅝ, ㅟ, ㅖ, ㅒ. It ends with ㅣ, ㅏ, or ㅓ. Therefore, if three consonants among five consonants ㄴ, ㄹ, ㅁ, ㅇ, and ㅎ that do not exist, and 3 vowels of ㅣ, ㅏ, and ㅓ are grouped and arranged in pairs, "Octogi <=> Wadugi" In the case of'Wadugi' even when inputting the hard sound as two basic consonants, it can always be correctly recognized as'Oudugi'.

In this case, it is possible to be recognized as "Octogi" without changing the existing algorithm only by the grouping above (because the existing algorithm checks whether a double vowel can be achieved). This has a property that when the first syllable (character) has a base and the next syllable (letter) starts with a tense, even if the same button is pressed two consecutive strokes to input a tense, it is not recognized as a vowel.

However, in the case where the hard sound becomes the first syllable at the beginning of the word (in the case where inputs 1 and 2 are confirmed as a hard sound, and inputs 3 and 4 are confirmed as vowels), a slight modification to the flow chart of the previous application is required. It is easy for those skilled in the art who understand the idea of. In this case (in the beginning of the word, input 1,2 is a hard sound, input 3,4 is a vowel, i.e., "ja+mo"), if input 1,2,3,4 are all the same button, input 1 is a plain tone, and input 2 ,3 There may be ambiguity between this vowel and input 4 being final (that is, "child+mother+child"). As in the flowchart of the previous application, it receives the next input ("input x" for convenience), By checking whether it is possible to form the final consonant and double support of "+mother + character" and whether it is the end of the word, double support cannot be achieved, and at the end of the word, input x is treated as the finality of "character + mother", overcoming ambiguity in some cases. There are cases where you can do it. In the case where the double support can be achieved, the same concept can be processed by receiving the next input and checking whether the word ends.

By treating the hard sound as a combination of the two plain tones in this way, even when ambiguity occurs, it can be viewed as ambiguity caused by applying the repetitive selection method, and through the "index" provided to overcome the ambiguity described below. You can overcome it.

In the end, there is some ambiguity anyway by applying the repetitive selection method, but by treating the hard sound (double consonant) as a combination of two basic consonants, it is possible to increase the convenience of input and improve the simplicity of the input method even if there is a slight increase in ambiguity. There will be.

Word can be distinguished through any means that can distinguish between words and words, such as blank space, mode change, move button, confirmation, and end of input.

2.5 Hindi

In the applicant's earlier application, Hindi consonants are grouped into 9 groups and assigned to buttons [1] to [9], so that the vowel assigned to the [0] button is selected with the [0] button 1 stroke. For consistency, 10 consonants are selected. It is possible to group into groups of dogs, and always select 1 stroke for the representative consonant and 2 strokes for 10 vowels. The vowel __(ri) that is not placed on the keypad and is not used often can be handled by the control processing method. In grouping consonants into 10 groups, as suggested in the previous application, a method of grouping in consideration of the similarity of pronunciation is possible. An example of grouping into 10 groups is as follows.

(a) 는 자음과 자음 사이에서 생략될 수 있다고 한다. 즉 자음이 연속하여 나오게 되는 것이다. 이러한 경우 "자음 + __(a) + 자음" 으로 입력하더라도 "자음 + 자음" 으로 표시되도록 하는 것은 매우 용이한 일이다. 물론 직접 "자음 + 자음"을 입력하는 것도 가능하나 이 경우 동일한 대표자음이 연속하여 선택되어 두개의 자음이 하나의 모음으로 인식될 수 있는 가능성이 많아진다. 따라서 양자(모음 __(a)를 자동 생략 혹은 사용자가 생략 입력)를 모두 허용할 수 있다.And the first vowel in Hindi

It is said that (a) can be omitted between consonants and consonants. In other words, consonants come out in succession. In this case, even if you enter "consonant + __(a) + consonant", it is very easy to display it as "consonant + consonant". Of course, it is possible to directly input "consonant + consonant", but in this case, the same representative consonant is successively selected, increasing the possibility that two consonants can be recognized as one vowel. Therefore, both (the vowel __(a) is automatically omitted or the user enters the omission) can be allowed.

2.6 Myanmar

There are 33 consonants in Myanmar. The following is an example of grouping these into 9 groups as in the Hindi example. Grouping into 10 groups can also be done by a similar trick.

3. Minimize ambiguity through a mathematical model in the method of using pairs of basic alphabets

In languages in which consonants and vowels appear repeatedly, such as Korean, Hindi, and Myanmar, 10 basic consonants and basic vowels are placed in pairs on the numeric buttons on the keypad, and the repeat selection method is applied on the buttons with little ambiguity. It has been shown that it is possible to efficiently input the alphabets arranged in.

In the case of Korean, it was suggested that hard, aspirated, and extended vowels can be input by combining control and basic alphabet. In the case of Hindi, it is suggested that the remaining consonants attached to the representative consonants can be input by subsequent control processing. Here, we present a method to reduce ambiguity as much as possible in the invention of the earlier application.

When multiple alphabets are assigned to one button on the keypad and the repetitive selection method is applied, the nature inherent in the repetitive selection method causes ambiguity as described in the previous application. For example, if you enter AB arranged on the same button consecutively, if you enter [2]+[2]+[2], it is impossible to know whether it is AB or BA.

For convenience, in the case of Korean as an example, most of the syllables in Korean are "consonant + vowel (abbreviated as "character + mo")" or "consonant + vowel + consonant (abbreviated as "character + mo + character")". It consists of a form. This is also the case for languages such as Hindi and Myanmar. However, in Korean, there is a characteristic that one syllable constitutes one letter.

Among the cases where ambiguity occurs, if the first syllable consists of "ja+mo" and the second syllable consists of "ja+mo+ja", the second syllable's "mo+ja" is placed on the same button. Then, the first consonant (initial vocal) of the second syllable is recognized as the last consonant (final consonant) of the first syllable, and the "mother+character" of the second syllable is recognized as "character+mo". In the end, in order to minimize this ambiguity, it can be seen that "mother + character", which is frequently combined in syllables consisting of "character + parent + character", should be avoided as much as possible on the same button. In other words, vowels and consonants with a high frequency of transitions from vowels (neutral) to consonants (lasting) in syllables consisting of "character + parent + character" in the corpus should not be placed on the same button. In the case of Korean, the same ambiguity may occur when the first syllable consists of "ja+mo+mo" or the second syllable consists of "ja+mo+ja+ja", but not many cases. In other words, in the case of Korean, it means that in the case where the second syllable consists of "character + mother + character + character", mother-to-child transfer should be considered together with the frequency of mother-to-child transfer, but not many cases.

Looking at the above case from the opposite point of view, if the first syllable consists of "ja+mo+ja" and the second syllable consists of "ja+mo", if the "ja+mo" of the second syllable is placed on the same button, the first The syllable is recognized as "ja+mo" and the second syllable's "ja+mo" is recognized as "mo+ja", and is recognized as "ja+mo+ja" by combining with the consonants of the previous syllable. In order to minimize this ambiguity, it is necessary to avoid placing "ja+mo" frequently combined in syllables composed of "ja+mo" on the same button as much as possible. In the case of Korean, the first syllable consists of "ja+mo+ja+ja", but this is not the case.

In addition to the above cases, other cases where ambiguity occurs have been suggested in the previous application, but since this is not a large number of cases, a method to minimize ambiguity is suggested by considering only these two cases. This applies equally to languages in which consonants and vowels appear sequentially, such as Hindi and Myanmar, as well as Korean, and is more easily applicable to other languages whose repetition rules for consonants and vowels are simpler than Korean.

In the case of selecting the basic consonants and the basic vowels arranged on the keypad in Korean based on FIG. 4-1 by the repetitive selection method, a flow chart for identifying the alphabet (preliminarily presented in the previous application) is introduced again, as shown in FIG. 4-4. same. In Fig. 4-4, a case where ambiguity occurs is also shown.

Hereinafter, for convenience, it will be described in detail through an example of Korean.

In Korean, about 50% of the syllables consisting of "ja+mo" (more precisely 54.011%), and about 50% of the syllables consisting of "ja+mo+ja". Therefore, the frequency of the transition from a consonant to a vowel in a syllable consisting of "child + parent" (abbreviated as "jamo transition" or "jamo combination") and the transition from a vowel of a syllable composed of "child + parent + child" to a consonant ( The frequency can be considered equal weight (abbreviated as "mother-to-child transfer" or "mother-to-child bond"). If the syllable consisting of "ja+mo" is about 70% of the total, and the syllable consisting of "ja+mo+ja" is about 30% of the total, then, the consonant transition is given a 30% weight on the frequency (consonants and Because vowels are assigned to the same button, ambiguity occurs on the premise of 30% of the preceding syllables ending in "ja+mo+ja"), giving 70% weight to the frequency of mother-to-child transfer (as opposed to vowels of mother-to-child transfer). The reason that consonants are assigned to the same button and ambiguity occurs is a premise of 70% of the preceding syllables ending in "Ja + Mo"), which should be considered.

The frequency of mother-to-child metastasis investigated in the literature is as follows. In Korean, there are 567 different vowels (neutral) and 27 consonants (lasting), and 270 of them are said to actually occur. It is said that the top 12 are 51% of the total, and the top 48 are 90% of the total. The large difference in transition frequency (combination frequency) means that ambiguity can be greatly reduced through optimized grouping (consonant + vowel). In the present invention, in the transition between vowels and consonants, it is not necessary to consider all cases since only the transitions between vowels and consonants displayed on the keypad need to be considered. It is easy to see that the combination of vowels and hard or aspirated sounds is because the "control" suggested in the previous application intervenes to remove ambiguity.

In the case of mother-to-child transition to be considered for minimizing ambiguity in the present invention, 10 basic consonants can be combined with 10 basic vowels displayed on the keypad, so there are 100 cases.

In the literature, the frequency of zygomatic metastasis is as follows. The following is a survey of only the frequency of syllables consisting of only "ja+mo". In the case of "child + mother + child", since it is considered in the frequency of mother-to-child transfer, it is not necessary to consider it here, and this is one of the important factors in the present invention. The number of jamo transitions is also the following 100 cases because 10 basic vowels can be combined with 10 basic consonants displayed on the keypad.

Since the above frequencies of mother and child transition are not relative ratio values, but absolute frequencies, a table indicating the frequency of consonant and vowel combination can be formed by summing them together. The following table is a summation of the frequency of mother-to-child and child-to-child transfer. To be more precise, as described above, the syllable consisting of "ja+mo" in Korean is about 54% of the total. Therefore, with a weight of 54% on the frequency of mother-to-child transfer, the syllable consisting of "ja+mo+ja" is Since it is about 46%, 46% should be given to the frequency of autophagy. However, in the table below, since the syllables consisting of "ja+mo" or "ja+mo+ja" in Korean occupy about half of each, there will be no significant difference. It was considered.

In general, the problem of minimizing ambiguity when applying the iterative selection method through the keypad is called the NP-hard problem. However, the problem of minimizing the ambiguity that arises when the applicant applies the (standard/simple) repetition selection method of consonants 1 stroke and vowel 2 strokes on the keypad in which the consonants and vowels proposed in the previous application are arranged in pairs is the problem of minimizing the ambiguity of the typical linear programming method. It can be modeled as, but this is also a great advantage of the applicant's invention. After all, the above table is a "table (integrated frequency table)" of the optimization problem to be mathematically modeled in the present invention.

In the invention of the earlier application, grouping of alphabets to be assigned for each button is called "grouping", assignment of grouped alphabets to each button is called "allocation", and placement of assigned alphabets on each grid on the button is called "arrangement." "Since it is called "grouping problem", the pairing of alphabets to minimize ambiguity according to this is called "grouping problem".

When the subscript of each row is set to i, the subscript of each column is set to j, and the number of consonants and vowels assigned, that is, 10 is set to n, the objective and constraint expressions are as follows.

Where each variable and coefficient is

0 : i 번째 모음과 j 번째 자음이 그룹핑되지 않을 때

0: When the i-th vowel and the j-th consonant are not grouped

1: When the i-th vowel and the j-th consonant are grouped

i 번째 모음과 j 번째 자음이 연속하여 나타나는 경우의 통합 빈도수를 의미

It means the frequency of integration when the i-th vowel and the j-th consonant appear consecutively.

Solving the objective expression in the above equation becomes as follows.

Likewise, it can be used by solving constraints. Since the mathematical model of the problem has been confirmed and the coefficient (transition frequency or coupling frequency) has been determined, solving the above problem can be easily solved using a commercial LP (Linear Programming) package. The result of solving the above problem is as follows. However, it is the result obtained by dividing the above integrated frequency table used as a coefficient for the program used by the applicant by 1/50.

However, even if grouping is performed to minimize ambiguity, it cannot be said that the grouping is the best. This is because the location identification of the alphabet on the keypad is also an important factor to consider.

Solving the problem to minimize the frequency of transitions (or conjugations) allows us to find pairs of consonants and vowels that minimize ambiguity. Conversely, if the above problem is solved to maximize the transition frequency, ambiguity arises a lot, but the convenience of input increases because the same button is often pressed when entering the alphabet. However, there is a disadvantage that the user must be aware of and cope with the case of ambiguity.

Maximizing the transition frequency (combination frequency) is to arrange vowels in pairs and to enter one consonant tarot and one vowel tarot, while pressing the confirmation button in units of syllables (characters in Korean) or selecting the confirmation control to confirm one syllable. If you do, it can be said to be very efficient. In this case, when inputting consonants and vowels that are not displayed on the keypad, all consonants and vowels can be input without ambiguity by assigning the subsequent control to the button where the final control is not placed, and allowing the subsequent control to be selected according to the number of repetitions of the control button. It is possible to do. However, there is a disadvantage in that the user has to force the inconvenience of pressing the confirmation button in units of syllables. As stated in the previous application, if this subsequent control button applies the same pre-input or post-input to consonants and vowels, one subsequent control button can be applied to both the subsequent consonants and subsequent vowels. Of course, this is the same even when the confirmation button of the syllable unit is not input.

Maximizing the transition frequency (combination frequency) is to solve the problem with the objective expression as "Max Z = ...". It is solved as a minimization problem by adding a minus sign ("-") to the coefficient (frequency) or the largest of the coefficients. You can solve the minimization problem by using the value minus each coefficient from the number as a coefficient. It can also be easily solved using a commercial LP package.

Although the combination of consonants and vowels does not take into account all cases where ambiguity occurs, it points out the most ambiguities (mother-to-child transitions, letter-transfers), and suggests a way to optimize based on the frequency of those cases. That is the "core" here.

In the end, if you reorganize the "core" of the method of minimizing ambiguity with a mathematical model, 10 consonants and 10 vowels are grouped into pairs and placed on each button, and each button 1 selects the consonants placed on the tarot keypad, and each button 2 In the method of selecting vowels arranged on the tarot keypad, the most frequent cases where ambiguity occurs are mother-to-child transitions (combination of vowels and consonants in a syllable consisting of "ja+mo+ja") and jamo transfer ("ja+mo"). In the syllable consisting of (combining consonants and vowels), it is pointed out that the consonants and vowels that are combined in the poem are assigned to the same button, and based on this, weight is placed on the frequency according to each transition type and modeled as the assignment problem of the linear programming method. This is the "integrated frequency table" that will be used as a coefficient when doing so. It is very easy to find out which groups of consonants and vowels can be optimized by solving this mathematically modeled problem using a commercial program.

This can be equally applied to languages such as Hindi and Myanmar, where one syllable is mainly composed of "ja+mo" or "ja+mo+ja". For languages other than Korean, data on the frequency of consonant and vowel transition (combination frequency) can be used with existing data. You can investigate and apply the method applied in the Korean example. In other words, as already explained, if 70% of the syllables composed of "ja+mo" in Hindi and 30% of the syllables made of "ja+mo+ja" are 70% of the frequency of mother-to-child transfer, You can put a weight of 30%. Also, in Hindi, there is a syllable composed of only "mother + child", which is always (ie, regardless of the shape of the preceding syllable), and there may be ambiguity that is recognized as "child + child", so this form of mother-to-child transition (simply "0 The frequency of "mother-to-child transition" or "0 mother-to-child combination") is 100% of the weight, so that the consonant and vowel pairs can be grouped to minimize the combined frequency table in three cases.

In the case of Hindi in the earlier application, grouping 10 basic vowels and 9 representative consonants into pairs can be solved as a problem of grouping 10 consonants and 10 vowels by adding false (pseudo) consonants. The frequency of transition (combination) between false consonants and 10 basic vowels is set to "0".

4. How to use vowel elements in Korean

4.1.1 How to control aspirated and hard tones

Korean vowel elements (ㅡ, ㅣ, .) can be used. See Fig. 4-5. In the present invention, 9 basic consonants out of 10 basic consonants [1] to [9] are assigned to each number button, and Korean vowel elements "ㅡ" and "" are displayed on the [*] and [#] buttons at the bottom of the keypad. Randomly assigns ㅣ" and assigns the vowel element "." to the [0] button. Various methods of assignment are possible, but for convenience, the assignment and arrangement of FIGS. 4-5 are illustrated in the present invention. Arranged basic consonants and vowel elements can of course be placed at the position of the reference grid, and there is no need to apply the partial whole selection method to the selection of the arranged basic consonants and vowel elements.

In the process of controlling aspirated sound and hard sound, "Aspirated Control" and "Aspirated Control" are randomly assigned to buttons on which "-" or "-" is placed, and are placed in a grid close to the reference grid among the remaining grids. In other words, the aspirated control and the horn control are selected for the button 2 strokes to which the control is assigned. A horn control (or aspirated control) can be additionally placed on the button assigned to the aspirated control (or aspirated control) so that it can be selected with the arranged button 3 strokes. As explained in the previous application, "ㅅ" does not have a pronounced sound, so "ㅆ" can be regarded as a hard sound and a pronounced sound. In addition, the aspirated control or the horn control does not necessarily need to be displayed on the button, and the user only needs to be familiar with the input rules.

For convenience, the state of selecting the aspirated sound control is represented as "{aspirated sound}", and when the control line input is applied in the example of Fig. 4-5, it becomes ㅋ = {aspirated sound} + ㄱ = [*]+[*]+[1]. . Likewise, ㄲ = {hard sound}+ㄱ = [*]+[*]+[1]. If it is allowed to select the horn control with the button 3 strokes assigned to the aspirated control, it becomes ㄲ = {hard sound}+ㄱ = [*]+[*]+[*]+[1].

In the present invention, the reason why there is no ambiguity even when the consonant control and the aspirating control are assigned to the same button with ㅡ and ㅣ among the vowel alphabet elements, and the repetitive selection method is applied, the vowel "ㅡ" is twice consecutively in the word. Because it does not appear, it is not recognized as selecting two vowels "ㅡ" + "ㅡ" when you press the [*] button 2 strokes to select the aspirated sound control in the example. The same is true of the vowel "ㅣ". The vowel "ㅣ" appears twice in the word "Polite" ([8]+[0]+[0]+[#]+[#]+[0]+[*]+[#] in the example) In this case, the vowel alphabet element "." As it follows, it can be seen that "[#]+[#]" here is a vowel, not the horn control selected. Because in the example, the vowel alphabet element "." Because the word cannot be terminated with, it is possible to know that the [#] entered after that is a vowel. Since the vowel "ㅡ" does not appear consecutively, there is no ambiguity even if the aspirated control and the aspirating control are assigned to the button to which the vowel "ㅡ" is assigned.

And since 9 consonants out of 10 basic consonants were allocated to 9 buttons ([1] to [9] buttons), the remaining basic consonants were not assigned to the buttons. For convenience, this will be referred to as "9 button drop-off consonants". For this 9-button drop-off consonant, considering the similarity of pronunciation or shape, one of the ten basic consonants is regarded as a modified alphabet or a subsequent alphabet, and control processing can be omitted. For example, "ㄹ" is not placed on the button, and "ㄹ" is regarded as a modified alphabet of "b" (abbreviated or hard sound), and ㄹ = [*]+[*]+ㄴ or ㄹ = [*]+[*]+[*]+ㄴ or ㄹ = [#]+[#]+ㄴ. In the example of FIG. 4-5, in consideration of the similarity between pronunciation and shape, "ㅎ" is regarded as a modified alphabet of "ㅇ" (abbreviated or hard sound), and ㅎ = [*]+[*]+ㅇ or ㅎ = [* It can be processed with ]+[*]+[*]+ㅇ or ㅎ = [#]+[#]+ㅇ.

In this case, the alphabet to be controlled ("ㅎ" in the example of Fig. 4-5) should be one of the alphabets (b, ㅁ, ㄹ, ㅎ, ㅇ) that do not exist for the convenience of entering the alphabet. . It is natural that the basic alphabet of the alphabet to be controlled ("ㅇ" in the example of FIG. 4-5) must also be one of the alphabets that do not have hard or aspirated sounds to add convenience of alphabet input. The reason for presenting an example of controlling "ㅎ" is that it is the lowest frequency alphabet among alphabets that do not have hard or aspirated sounds, and that do not exist. It is also because there is similarity in pronunciation, and similarity in shape as in the relationship between other plain and aspirated sounds.

Here, in order for Korean to be used for memorizing phone numbers and various codes, it is preferable that 10 basic consonants (plain sounds) are arranged on 10 number buttons. Therefore, "ㅎ" can be additionally assigned to a button assigned with "." ([0] in the example of FIG. 4-5) and placed on a grid in which "ㅎ" can be selected for 3 strokes of the button. This is because "." appears twice in a row, so in order to avoid ambiguity by applying the repetitive selection method, it must be selected at 3 strokes. Even in this case, even if "ㅎ" is not physically placed on the grid 3rd closest to the reference grid, the user only needs to be aware that they can select "ㅎ" with the corresponding button 3 tatami. This means that "ㅎ" can be input to the [0] button 3 strokes, but it can be usefully used for various memorization by arranging all basic consonants on each number button.

In Fig. 4-5, consonants are indicated in blue, vowels or vowel elements are indicated in red, and numbers are indicated in black in order to increase the discrimination of the alphabet. Indicating "ㅡ" in blue on the [0] button means that ". + ㅡ + 0(zero)" is an overall "ㅎ" shape, so "ㅎ" is implicitly assigned to the [0] button. Show.

That is, the 9-button drop-out consonant may be considered as a modified alphabet of a specific basic consonant, and may be input as a control processing method, or may be input as a button 3 strokes with the vowel element "." assigned at the same time.

And as mentioned earlier, using the property that "ㅡ" and "ㅣ" do not appear consecutively in Korean, 9-button drop-out consonants (for example, "ㅎ") are placed in buttons such as "ㅡ" or "ㅣ" It is also possible to input the corresponding button 2 tarot 9 button dropout consonants. In this case, one of the horn control or aspirated control is "." It is assigned to another button along with the button, and you can select the control assigned to the corresponding button 3 strokes. In other words, this means that it can be arbitrarily done in grouping 3 types of 9-button dropout consonants, aspirated control, and hard sound control and 3 vowel elements (ㅡ, ., ㅣ).

4.1.2 Basic consonant combination processing of hard sound and concealed/non-concealed repetitive selection processing of hard sound and aspirating sound

In the method using Korean vowel elements, hard sounds can be treated as a combination of basic consonants. Moreover, in the method using the vowel element, one basic consonant is assigned to the number button, so even if the hard sound is treated as a combination of basic consonants, as in the current 2 beolsik keyboard, only in the case of "Ottogi" <=> "Oudugi". Ambiguity (primary ambiguity due to ambiguity between full codes) occurs. (In "Oc", "c" is the last name)

However, it can also be solved by having an "index" to avoid ambiguity when it occurs. In the end, in the case of inputting the hard sound as a combination of basic consonants, only the aspirated sound needs to be input by the control processing method, so that the input rule can be further simplified. The aspirated control can be placed in an appropriate grid as described in the previous application. For example, in Fig. 4-1 or 4-2, the horn control is removed.

Also, input in the order of basic consonant, aspirated, and hard (for example, ㄱ, ㅋ, ㄲ) according to the number of times the button is pressed (for example, ㄱ=[1], ㅋ=[1]+[1], ㄲ= [1]+[1]+[1]) can be done. Even in this case, as stated in the previous application, primary ambiguity may arise. Specific cases where ambiguity occurs are not introduced here. In this case, it was said that basic consonants, aspirated sounds, and hard sounds can all be displayed on the button, or only basic consonants can be displayed. This is to select the subsequent alphabet (for example, ㅋ, ㄲ) by the iterative selection method.

Here, a method of displaying only the representative alphabet and selecting the remaining subsequent characters by the repeat selection method will be referred to as "hidden type repeat selection processing method" for convenience. Again, the sub-order of hard and aspirated can be placed in the order of basic consonant-hard sound-aspirated sound. For example, ㄱ(1st: standard grid position), ㄲ(2nd), ㅋ(3rd). That is, ㄱ = [1], ㄲ = [1]+[1], ㅋ = [1]+[1]+[1]. It can be seen that the double consonants are treated as a combination of basic consonants (or hidden repetitive selection processing), and even aspirated sounds are selected by the hidden repetitive selection processing method.

In this case, only the hidden repetitive selection processing method suggested in the previous application and the order of the subsequent alphabets are different, but by allowing the user to input with the number buttons 2 strokes (combination of basic consonants) when entering a hard sound, the naturalness from the user's point of view can be doubled. have.

In addition, when "ㅎ" was entered, the [0] button was entered with 3 strokes, but the relationship between "ㅇ" and "ㅎ" is similar to the relationship between the plain tone (basic consonant) and the aspirated tone in shape and pronunciation. As a result, it is possible to increase the consistency of the overall usage method.

Here, when entering "ㅎ", it is possible to input by the control processing method by considering "ㅎ" as a modified alphabet of "ㅇ" while allowing the input by 3 strokes of the [0] button assigned with "ㅎ". It goes without saying that it is possible to input the abbreviated sound with the button 3 strokes (or 2 strokes) to which the corresponding basic consonant belongs, and at the same time allow any number of inputs by the control processing method. When the user inputs aspirated sound by the control processing method, the system can identify aspirated sound without ambiguity (ambiguity between full codes, that is, primary ambiguity) when inputting aspirated sound. This can lead to ambiguity. The same is true for hard sound.

That is, in the same keypad, the user may input by the control processing method or by the hidden repetitive selection method when inputting the aspirated sound, and the same applies to the hard sound. For example, select the [*] button 2 strokes for the aspirated sound control, and at the same time select the button 2 strokes and 3 strokes to which the basic consonant belongs. When entering "khaki", "khaki = [1]+[ *]+[*]+[#]+[0]+[1]+[1]+[1]+[#]" That is, the first "ㅋ" can be entered as the control processing method, and the second "ㅋ" can be entered as the repeat selection method. Similarly, for "kaki", you can say "kaki = [1]+[#]+[#]+[#]+[0]+[1]+[1]+[#]".

When inputting the hard and aspirated sounds by the unhidden type repetitive selection processing method or the concealed type repetitive selection processing method, the selection order of the hard and aspirated sounds can also be set at the user's convenience.

4.1.3 Mixed application of the method using pairs of basic letters and the method using vowel elements

The method of using the vowel element can be seen as a more simplified keypad of FIGS. 4-1, 4-2, and 4-3, and can be compatible with alphabet input methods in the prior application. In other words, the alphabet input method of this application can be applied to the keypad displayed on each button in addition to 10 basic vowels, and furthermore, the entire display pad displaying basic consonants, basic vowels, extended vowels, aspirated sounds, and hard tones, etc. The input method of the application can be applied.

In the example of Fig. 4-2, the horn control and the aspirating control are assigned to the [*] button or the [#] button, but even if not indicated, the user needs to be aware of it, so each button is indicated by "-" or "-" as in the example of the present application. By marking "ㅣ" etc., the method using the vowel element and the method using the pair of basic letters can be selectively used. For example, in Fig. 4-5, 8 basic vowels excluding vowels "ㅡ" and "ㅣ" existing as vowel elements are assigned to 8 buttons among 9 buttons of [1] to [9], and assigned 8 The basic vowels can be selected from the button 2 strokes assigned to the basic vowel. Similarly, a control processing method or an iterative selection processing method can be applied to the input of aspirated and hard sounds. For example, assuming that 8 vowels excluding "ㅡ" and "ㅣ" in addition to FIG. 4-5 are arranged as shown in FIG. 4-2, when the word "gasin" is entered, "gasin" = [1]+ It can be something like [3]+[3] + [7]+[#]+[2]. According to the user's convenience, the vowel "ㅏ" of "A" applies the repetitive selection method, and the vowel "I" of "Shin" can be input by using the button on which the vowel element is arranged. In vowel input, different methods are applied within the same word, but no input mode change is required.

In addition, 8 vowels are additionally assigned to the [1]~[9] buttons, and two basic consonants that are similar in shape and pronunciation among the basic consonants that do not have hard and aspirated sounds (for example, b/ ㄹ or ㅇ/ㅎ, etc.) can be placed together and the repetitive selection method can be applied. The ambiguity that may arise in this case can also be overcome through the "index" described below.

5. How to overcome ambiguity through indexing

When applying the repetitive selection method, multiple words may be expressed as a single code, resulting in ambiguity. In the input example of Fig. 4-1, it was pointed out that there is an ambiguity in which "goi" can be recognized as "awesome" and "awesome" as "goi". By the way, the word is usually entered in units of words. For example, the word "great" exists, but the word "goijang" does not exist. In Fig. 4-1, both have the same code value. Therefore, in response to this, indexes for words that may cause ambiguity about a specific keypad and a specific alphabet input method are prepared and registered on the terminal (client) or server side. When "Great" or "Goijang" is entered, when both cannot be distinguished by time delay, etc., if "Great" is registered as the correct word in the index, the word the user wants to input (for convenience, hereinafter "Target word") is what you can see is "great". This applies only when ambiguity that cannot be distinguished by the system occurs, and when it is possible to distinguish it by the time delay value defined by the system (terminal side or server side system) or the time delay value defined by the user, it is natural to follow it. . In other words, if the user intentionally cuts off (using a time delay or blank, or using the right-hand button or other specific button), even if it is a word that is wrong in meaning, the word is the target word, so it is Should print ".

The way to prepare the index is to register only the correct words ("great" in the example) for words where ambiguity may occur, or you can register only the wrong words ("Goijang" in the example). Also, it is okay to register both the correct and the wrong words, and the system only needs to have information about which words in the index are correct or wrong words.

This can be applied in all cases where the repetitive selection method is applied in the keypad. For example, an ambiguity such as "Country <=> Guka" occurs in the input method of Samsung Electronics in Korea, which can also be applied here. In addition, similar to Fig. 4-1, when a pair of letters is placed on each button, and a consonant 1 stroke, a pronounced 2 stroke, a consonant 3 stroke, and a vowel 1 stroke are selected, and the syllable completion button is pressed in units of syllables (characters). It can also be applied to When the user inputs "Awesome", even if the "Great" is temporarily output, it is possible to correct it to "Awesome" by referring to the index at the moment when the word ends (for example, inputting a blank space).

At this time, if the index of the word exists on both the client side and the server side, the index of the client side is firstly searched to try to identify the correct word, and when the identification fails, the index of the server side is secondly searched and finally the correct word. Can be identified.

To distinguish the unit of a word, as anyone can think, it is only necessary to identify it by the element that separates the word from the word. For example, you can think of the case between a space and a space, between the beginning of a word and a space, between a space and the end of an input, between a space and a mode switch, and so on. Since determining the correct word by referring to the index is performed in units of words, index reference is made when an element that distinguishes the word is input, and the correct word can be determined.

This can be applied in all cases where ambiguity occurs by applying the iterative selection method. For example, in the Samsung Electronics method currently used in Korea, ambiguity may occur if the last and first consonants belong to the same button. For example, "country" <=> "guka". When entering a code for each alphabet, it is input without recognizing the syllable (letter) unit. In fact, in many cases, if you unconsciously enter "country", it becomes "guka". In this case, if it is not possible to know which of the two words is the target word by a time delay or the like, the system (terminal or server) can find the target word by referring to the index. However, in this case, even if the final "a" of "guk" and the initial "a" of "a" are pressed in succession, in most cases, the target word is often "country", so the index is indexed regardless of the time delay. A method of identifying the target word by reference can also be effective.

In addition, it is obvious that this is not limited to Korean only and can be applied to all languages in the case of using the repetitive selection method. For example, in English input or in the English mode of another language keypad, when there is an ambiguity that does not know whether the input of [2]-[2]-[2] is "AB" or "BA", "AB" If is registered in the index with the correct word, it can be recognized and provided to the user as a target word. If a plurality of ambiguity-occurring words are registered in the index as correct words, words with a high frequency of use are primarily provided to the user, and the user can finally determine the target word.

If there is ambiguity about the input of a word, even if referring to the index, if all the words corresponding to the input are recognized as correct words, the user can be given feedback through an appropriate method (visual or audible) to select. .

The method for allowing the user to determine the target word is to arrange a plurality of words recognized as correct words in the display window in the order of frequency of use (or priority order), and use the numeric buttons corresponding to the displayed order by scrolling up and down. This allows the user to determine the target word. Alternatively, by selecting a control (called "Next Word Control" for convenience) that displays only words with high frequency use and displays the next word if it is not the target word, the next most frequently used word is displayed. If, again, the target word is not the target word, the target word can be searched continuously by selecting the next word control again. In this case, after searching for the target word, the target word can be confirmed by pressing any other button (for example, selecting a different alphabet, blank, mode switching, etc., not selecting the next word control selection, but by pressing all buttons). .

The selection of the next word control can be applied to either the "partial whole selection method" or the "repetitive selection method (standard/simple)" described in the previous application. If it is assumed that the next word control is arranged at the position of the reference grid of a specific button, the next word control will be selected with one stroke of that specific button.

6. Simple code utilization method and shortened input method/parallel input method

6.1 Alphabet-related simple code generation method

When accessing an information system using an information communication terminal, it is essential to enter the alphabet. Or, you can enter the alphabet to be input by converting it into a numeric code. In a miniaturized information communication terminal, a keypad-type interface is usually used in many cases. The code here refers to all kinds of codes, and representative examples include telephone numbers, securities (listed companies) codes, city codes, department codes, subway station codes, and bank codes. The advantage of coding and inputting various names is that the input can be simplified.

Information and communication terminals include all types of information and communication terminals such as PCs, mobile communication devices, smart phones, PDAs, two-way text transmission and reception devices, and ATMs (automatic teller machines). In addition, it covers terminals that do not have communication functions such as electronic notebooks. The information system includes all types of systems such as systems that can be accessed visually through GUI as well as systems that can only be accessed with sound, such as ARS. In addition, the system refers to a server-side system in a narrow way, and broadly includes a client software of a terminal compatible with the server system.

It can be usefully used for memorizing various codes by using the alphabet arranged on the keypad. In using it for memorization of codes, there may be methods of simple naming, initial naming, and full naming. The brief summary of the contents is as follows.

Simple naming is to designate a number associated with a word or phrase to be coded (the word or phrase is collectively referred to as "phrase" below) as a code. For example, in the case of a Korean company name code, the code of “Gasan Electronics” is referred to as “1799” associated with a, ㅅ, ㅈ, ㅈ as a simple code based on FIG. 4-2. In this case, it is possible to make it easier to know the simple code of a specific word by highlighting the ㄱ, ㅅ, ㅈ, ㅈ related to the simple code "1799" in "Gasan Electronics", and furthermore, the simple code from such phrases You can also extract it. In the case of simple naming, since a number associated with a certain alphabet belonging to a word to be coded is determined as a code, it is not necessary to set the code of the example “additional electron” to “1799”. For example, just as the simple code of "stocks" can be the value associated with ㅈ, ㅅ, ㅣ, ㄹ, in the case of Gasan Electronics, for example, "1729" related to ㄱ, ㅅ, ㄴ, ㅈ It can be done as, it can be set as “1749” related to a, ㅅ, ㅓ, and ㅈ, or it can be set as “13294293” related to the entire alphabet constituting “additional electrons”. For convenience, a simple code related to the entire alphabet constituting a phrase is referred to as "all related simple naming", and for convenience, designating a simple code related to some alphabets of a specific phrase is called "partial related simple naming". In any case, simple naming (that is, simple code) can be viewed as specifying a code in association with the alphabet constituting the phrase in units of phrases. This is similarly applicable to languages other than Korean. For example, in "captain", "2786", which is related to the consonant "CPTN", can be used as a simple code, which is a partially related simple code, which will be called "consonant related simple code" for convenience.

Not only words but also phrases can be coded by simple naming. Using the letter (syllable) that best implies the meaning in the phrase "Where are you going" as an example in the previous application, "8314", which is mapped to ㅇ, ㄷ, ㄱ, and ㄹ, can be used as a simple code. In the case of English, "3886" related to d, t, t, and n, which has a phonetic value of "date tonight" as an example in the previous application, can be used as a simple code.

Initial naming is a special case of some related simple naming. In the case of Korean, initial naming may be a method of designating a number mapped to an initial consonant (first consonant) based on a syllable (character) as a code. This is called "syllable (letter)-based initial naming" for convenience. In the case of "Gasan Electronics", the initial code based on the syllable-based initial naming becomes "1799", which is related to the consonant initiality of each syllable (letter). The syllable-based initial naming can also be applied to languages other than Korean. For example, in the case of English, an initial code based on syllable-based initial naming of the word "entertainment" may be "3886" related to e, t, t, and m. The syllable-based initial naming can be more useful in the case of Korean, in which one syllable constitutes one letter.

Likewise, initial naming is possible for phrases. In the phrase "Where are you going" as an example in the previous application, "81", which is associated with the first alphabet of each word, ㅇ and ㄱ can be used as the initial code. In the case of English, for the phrase "dance with the wolf" as an example in the previous application, the initial code is word-based initial naming, and "3979" associated with d, w, t, w becomes the initial code. The word-based initial naming can be usefully used in all languages when code is assigned to the entire phrase.

For convenience, it is sometimes referred to as "simple code" or "short code" for convenience in terms of simple code (simple code related to all, simple code related to couple) and initial code (syllable-based initial code, word-based initial code). . All-related simple codes, consonant-related simple codes, syllable-based initial codes, and word-based initial codes are particularly regular in the generation of their codes, so they can be used universally, and if others have generated simple codes with such rules It can also be used easily.

Full naming is an input value of a phrase to be coded by a specific character input method. Therefore, this may vary depending on the applied character input method, and it can be seen that a numeric value corresponding to a certain phrase in alphabetical units is used as a code. In the case of "Seoul" as an example in the earlier application, the full code according to the partial-total selection method (referred to in the earlier application) is "7745888944" based on FIG. 4-2. If the standard repetition selection method (as mentioned in the previous application) the full code is "7448884". If a keypad different from that of FIG. 4-2 or another alphabet input method is applied, there will be a full code value accordingly.

6.2 Tone-based simple code generation method

In terms of meaning characters such as Chinese, a method is needed to reasonably match countless characters with buttons on the keypad. One way is to map the English pronunciation of Chinese to the alphabet on the English keypad. As another method, we propose a method of mapping to keys on the keypad by using the tones of Chinese characters, which are meaning characters.

자 형을 이루게 된다. 또는 1 성조 ~ 5 성조를 각각 [1] ~ [0] 의 10 개 버튼에 각각 순서대로 2 개의 버튼에 대응시킬 수 있다.All Chinese characters have five tones. 1 surname (tonal sign -), 2 surname (tonal sign ′), 3 surname (tonal sign ˇ), 4 surname (tonal sign,), and silent letters. It can correspond to each of the two buttons on each of the five tone keypads. Several methods of arrangement are possible in this framework. For example, 1 tone is matched to button [1] and button [2], 2 tone tone is matched to button [3] and button [6], and tone tone is matched to button [4] and button [7] , 4 Tones can be associated with buttons [8] and [9], and silent tones can be associated with buttons [5] and [0]. This is to consider the convenience of use by placing 1 to 4 tones on the up/down/left/right buttons on the keypad. If you change the color for each of these button pairs, you can get a better visual effect. In the top, bottom, left and right arrangement, setting the button pair to [1, 2][3, 6][4, 7][8, 9]

It will form a shape. Alternatively, 1 to 5 tones may be associated with 10 buttons of [1] to [0], respectively, to 2 buttons in order.

Here, it becomes a problem to determine which of the buttons [1] and [2] the letter with one tone corresponds to a letter. There can be several ways to do this too. For example, there is a method of classifying by the number of strokes (that is, one of the methods of determining the complexity of a letter). If the number of strokes of a letter with one tone within a word or sentence is less than a certain number of strokes (for example, 5 strokes), it is judged as the letter corresponding to the [1] button (the smallest number of buttons [1] and [2]) Otherwise, it is judged by the letter corresponding to the [2] button (the largest number of buttons [1] and [2]). Five strokes are illustrated as the number of strokes used as the criterion for judgment.This is not the average number of commonly used (commercial) kanji (kanji), but the number of characters less than a certain stroke by examining the kanji is about half of the total number of characters and exceeds a certain number of strokes. It is possible to determine the number of strokes based on a standard that is about half of the total.

Among the methods of determining the complexity of a letter, a method based on the number of strokes has been suggested, but another method is also used to determine the number of element letters. Element characters are characters that can be identified within one Chinese character. For example, it can be seen that the castle consists of two element letters (土 + 成), and 禁 consists of three element letters (木 + 木 + 示). Therefore, if it is less than a certain number of element letters (for example, two) among two buttons corresponding to the same tone, it is judged as a letter corresponding to a smaller number of buttons, and if exceeded, it is determined as a letter corresponding to a larger number of buttons. I can judge.

The tone in Chinese is shown in Fig. 5-1. The tonal code is commonly used, and the tonal code of FIG. 5-1 is used in the present invention. Figure 5-2 shows an example of a keypad in the present invention in which tonal codes are displayed on a keypad button. In the example, since 1 tone is assigned to button [1] and button [2], 1 tone symbol (-) is added on buttons 1 and 2. Displayed smaller on the 1 button and larger on the 2 button is the letter corresponding to the 1 button if the complexity of the letter (number of strokes or number of element characters) is less than a certain level (for example, 5 strokes, 2 element letters). This is to make it easy to intuitively judge what is to be judged. Referring to FIG. 5-2, a result of coding a number of words by corresponding to the keypad is shown as follows. In the following example, the number of strokes "5 strokes or less" was applied as the criterion based on the complexity of the letters. The sign above the letter is the tonal sign.

If different words generate the same code in the system, it is possible to avoid duplication by attaching a serial number after the word string. For example, if a character with a numeric code such as 百貨公司 code 7612 exists in the system, the serial number is assigned as 百貨公司 1 and the code is generated and interpreted as 76121.

When a user inputs a character to designate a tonal-based simple code, the system extracts a simple code corresponding to the inputted character according to a pre-defined tone-based simple code generation rule in the system and displays it to the user. The difference between Chinese, which is a meaning character, is that the system does not simply require mapping information between letters and numbers, but requires that the tonal tone and the number of strokes (or elemental characters) can be known by referring to the dictionary.

In the present invention, a method of mapping Kanji (Chinese characters) to buttons on a keypad is proposed based on Chinese tonal characteristics and character complexity. Due to the nature of Chinese, five tones are assigned to two buttons, so it can be intuitively convenient to arrange the current keypad arrangement in a two-column and five-row arrangement. In other words, for example, buttons [1] and [2] are placed on the first row of the keypad, buttons [3] and [4] are placed on the second row, and buttons [5] and [6] are placed on the third row. Then, the [7] and [8] buttons are placed in the fourth row, the [9] and [0] buttons are placed in the fifth row, and the [*] and [#] buttons are placed in the sixth row. 1 tones, 2 tones, 3 tones, 4 tones, and silent tones are assigned to each of the 2 buttons in each row, and whether the letter corresponding to the button in the column 1 is judged as the letter corresponding to the button in the column according to the criteria such as the complexity of the letter, it corresponds to the button in the 2 column You can decide whether or not to judge by the letter that you say. The arrangement of the buttons on the 2*6 keypad may be in the same manner as in FIG. 5-3. In this case, it is possible to allocate each tone to two buttons in each row, and determine whether a letter corresponds to a button in one or two columns according to the complexity.

If only one standard is not used and multiple methods are used, the generated code value will be different as the keypad buttons assigned to the tone are different. Therefore, conversion between a generated code by a specific method (eg, a code by a 3*4 keypad in the present invention) and a generated code by another method (eg, a code by a 2*6 keypad in the present invention) I need this. The conversion can occur on the server side or in the terminal-side client software. In any case, it can be seen that conversion occurs within the entire system (server + client), and if you know which method is applied in the entire system, you can reconvert it into the necessary code. For example, if the code value of 人民日報 by Method 1 is input and the value required by the system is the code value by Method 2, the system can obtain the code value by Method 2.

If you do not want to generate a code with 百貨公司 and want to generate a code with 百貨, you can display only 百貨 by entering 百貨 in combination with a specific function key when entering, and create only "76" for 百貨公司 as a code. I can. Furthermore, if you want to create a code based on only a part of the letter (for example, the hwa of the letter) (for code redundancy, etc.), only the 化 is displayed in the letter by emphasizing it, and the code is generated based on that. I can make it. In other words, in this case, the simple code of 百貨公司 (shown by highlighting only the 白貨公司) is "7312" instead of "7612".

As for Chinese input method, it is common to input English corresponding to Chinese pronunciation and select and input the corresponding Chinese characters when convertible Chinese characters are made using the "Hanja conversion key", like the Chinese character input method in Korean.

In Chinese, the full code can be determined based on the English pronunciation of Chinese. Furthermore, when there are multiple words with the same pronunciation, a code by English pronunciation, a Chinese character conversion key, and a ranking of a target word among the same pronunciation words may be summed to determine a full code. In the example of the present invention, the [*] button is used in both of FIGS. 5-2 and 5-3 for the Chinese character conversion key when input from the keypad. In the present invention, the English input method is not specifically mentioned, and an existing method is used.

In the present invention, it is necessary to put a "specific function key" for simple naming in Chinese. In other words, after entering English and entering the Kanji conversion key to select the desired Chinese character, and entering a specific function key for simple naming (this is called "Simple Code Key" here for convenience), the character and the element characters constituting the character Are displayed in order, and among them, element letters for simple code generation can be selected. In the example of the present invention, the simple code key [#] button is used.

In the example above, if you enter 貨 in 百貨公司 and then enter a simple code key, the 貨 characters themselves such as 貨, 化, and 貝 are displayed in order, and if you select the second 化, only 化 in 貨 appears. It is displayed and the corresponding simple code is recognized as 3 in the system. Recognition of the displayed 貨 with only 化 as simple code 3 is recognized as 3 immediately after input, stored in the system, and used later, or interpreted from characters and used.

In Chinese, it is necessary to have a Chinese dictionary in the entire system (client side or server side) for naming code. That is, when a user inputs a named character, the system can map the named character to a numeric code by referring to the tonal tone, the number of strokes (or the number of element characters), etc. from the dictionary. It is assumed that the dictionary has tones that can map Chinese characters to numbers on the keypad, and the number of strokes or element characters. The user or system administrator must be able to add words that are not registered in the dictionary and store the relevant information necessary for mapping such as tones. However, if the entire system does not have a Chinese dictionary, the user must be able to input mapping information such as tones when entering a word as a named character, or to be able to enter a numeric code corresponding to the character.

In the case of Chinese, generating a simple code based on tonal tone has the advantage of not generating a simple code based on English pronunciation, and intuitively matching one number code for each character. In addition, in Chinese, the company name and city name are all composed of a certain number of characters.Since the length of the simple code based on tones matches the number of letters (the number of tones), the length of the code can be fixed, and the English alphabet is not added. There is an advantage that it can be used even on a keypad that is not used.

This can be applied to all tonal languages such as Thai and Myanmar. Every syllable in Thai has a tone. There are five tones in Thai: Pyeongseong, 1 Star, 2 Star, 3 Star, and 4 Star. Therefore, as in the case of Chinese, it is possible to associate each tone with two buttons on the keypad. And, as in the case of Chinese, when one tone is matched to two buttons on the keypad, it is necessary to determine which of the two buttons corresponds to a certain criterion such as the number of strokes or element letters. Various standards are possible, but in Thai, there are two types of vowels combined for each syllable: short vowels and long vowels, so the short vowel may correspond to a small number and a long vowel may correspond to a large number.

In addition, tonal codes are added to explicitly indicate tones (typical tones), and tones are not added (there are four), and five tones are expressed according to the type of consonant, the length of the vowel, and the presence or absence of the seed consonant. It can also be a (non-formation group). Thai consonants are divided into 9 medium consonants, 10 high consonants, and 23 low sounds, and even in the case of a tangible tone with the same tone code added, different tones can be made according to the type of consonant. Therefore, regardless of the actual tone, the case where 4 tonal symbols are added and 5 cases where the tonal symbol is not added are corresponded to the two buttons on the keypad, respectively, and also depending on whether the combined vowel is a short or long vowel, Simple code can be set. This is specifically referred to as "simple code based on tonal code".

In the case of Myanmar, there are three tones: 1 tones, 2 tones, and 3 tones. All three tones are indicated by adding tonal codes. Therefore, each tone can be associated with each of the three buttons to the buttons [1] to [9]. For example, a syllable of one tone corresponds to the buttons in the first row (buttons [1], [2], and [3]). One of the criteria for dividing the syllables of the same tone into three types: a syllable without a seed sound (e.g. letter + parent), a syllable with no first consonant and only seed sound (e.g. parent + letter), and the first and seed sound modes. You can use the criteria for classifying with syllables (eg, letter + parent + letter). For example, if a syllable is a one-tone syllable, it can be considered to correspond to one of the [1], [2], and [3] buttons, and the syllable consists of "ja+mo" without a seed sound. If you lose, the syllable is supposed to be associated with the [1] button. Since all the syllables in Myanmar language have tonal symbols and the syllable composition rules can be known mechanically, it has the advantage of mechanically generating a tonal standard simple code for all words by applying this.

6.3 Unique Simple Code

When the simple code can be decoded on the client side (that is, when the client side has a specific phrase and a simple code value corresponding to the specific phrase), the phrase corresponding to the input simple code is transmitted to the server side. I can. Even if the client side can decode the simple code, if the server side requires a simple code according to the nature of the application, the simple code itself (i.e., a number sequence) can be transmitted to the server side. Just interpret it. This means that the decoding of the simple code can be done on the client side or on the server side.

When a simple code is defined and used for a plurality of phrases, there may be multiple phrases corresponding to the same simple code. This ambiguity that can occur between simple codes is called "second order ambiguity" for convenience. In this case, it is possible to create and store a unique code value by adding a serial number to a simple code having the same value inside the system, but a second ambiguity occurs because the user mainly uses a simple code related to a specific phrase. In this case, it is natural that the system should be able to recommend such phrases to users according to their usage priority. In the case of having the same simple code while being a different phrase, the serial number can be used as a priority for recommending the serial number to the user by attaching a serial number to the simple code according to the priority according to the frequency of use of the phrase inside the system. Of course, it is not necessary to attach a serial number, and the system may have a separate priority information, and is just an example of how it can be done.

For example, if the simple code of "Stock Information" is the same as "9196", which is a syllable-based initial code, and "9196", which is also the syllable-based initial code, the serial number according to the frequency of use of each word. And the serial number can be used as a priority to recommend to users. If the frequency of use of "securities information" is high, priority can be given to "securities information" = "91961" and "stock information" = "91962". The simple code generated by adding a serial number in this way is referred to as a "unique simple code" for convenience, and a simple code with redundancy without a serial number is simply referred to as a "simple code". "It is called.

6.4 Simple Code Use Case

An example of assigning a simple code (syllable-based initial code) to a city name is as follows. This can be usefully used in railway information systems and the like.

. Seoul = 78, Suwon = 78, Daejeon = 39, Shintanjin = 739,...

Here, since the syllable-based initial codes of Seoul and Suwon are the same, in order to avoid this, simple codes such as "Seoul = 781" and "Suwon = 782" can be made unique in the system to avoid this. When the user sends only "78" to the system, the system gives appropriate feedback (eg, provides a list of Seoul and Suwon or informs them by voice), allowing the user to choose between Seoul and Suwon. If the user recognizes this from the beginning and enters "781", the system can recognize it as "Seoul".

If the server-side system does not require the simple code "78" but needs the word "Seoul", the client side interprets the simple code "78" and transmits "Seoul" to the server side. Alternatively, even if the client side can interpret the simple code, if the server side requires the simple code itself according to the nature of the application, the inputted simple code itself can be transmitted to the server side.

Again, an example of a stock item (listed company) is as follows. This can be usefully used in various securities information systems.

. Dongwha Pharm = 3098, Digital Chosun = 39397, Hantong Freetel = 83643,...

Here, for example, in the case of "Digital Chosun", by emphasizing and displaying "C, ㅈ, ㅌ, ㅈ, ㅅ" used as the basis of the syllable-based initial code, a better visual effect can be given to the user.

An example of a bank code is as follows. This can be usefully used in ATM machines and various financial information systems.

. Kookmin (Bank) = 14, Hana (Bank) = 82,...

Here, it is obvious that when the user inputs such a predefined simple code, it can be interpreted on the client (terminal) side and displayed to the user so that it can be used for phrase input. This is referred to as the "shortened input method", and will be described in detail with the "parallel input method".

6.5 Automatic reassignment of priority according to selection frequency

Furthermore, if the priority of "securities information" and "sovereign information" was first and second, respectively, but the number of times a specific user selects "sovereign information" is remarkably high, the priority of "sovereign information" It can be adjusted to be higher than the priority of "securities information". There are various methods as described, but this can be realized by changing the serial number. If the priority information is separately in the system, it is possible by changing the priority information.

The criteria for determining whether the number of times to select "sovereign information" is remarkably large may be determined by the system or may be (re)designated by the user. For example, if a different priority is selected at least 8 times out of 10 times from the previously designated priority, the existing priority may be automatically corrected. Depending on the option, the user may be asked to confirm the correction.

6.6 Simple code automatic designation and simple code-related alphabet highlighted

In particular, consonant-related simple codes, syllable-based initial codes, and word-based initial codes, in addition to all-related simple codes, have regularity in generating simple codes as described above, so when the user designates a simple code for a specific phrase, the simple code generation rules If you enter a specific phrase in the state specified, the corresponding simple code can be automatically extracted and stored in the system. In addition, it is possible to increase the convenience of use by highlighting and displaying the alphabet related to the simple code. In the case of English, the alphabet related to the simple code is highlighted and displayed, but can be displayed using uppercase letters.

Also, in the previous application, "shortened input method" and "shortened/full parallel input method" were suggested. The simple code for shortened input can be defined in the system, the user can change it, and the user can designate a simple code for a new phrase.

In deciding a simple code for a new phrase, simple code generation rules such as all related simple codes, partial related simple codes, consonant related simple codes, syllable-based initial codes, and word-based initial codes introduced in the previous application can be used. For example, if the user wants to use the word-based initial code as a simple code when generating a simple code for "dance with the wolf", enter "dance with the wolf" in the simple code generation mode, and You must enter the word-based initial code "3983". Similarly, in generating a simple code for "securities information", if you want to use the syllable-based initial code as a simple code, you must enter "securities information" and then "9196" in the simple code generation mode.

However, if a user designates a simple code for a specific phrase, the system remembers the type of simple code the user wants and inputs the phrase to generate the simple code, without having to enter the code for the specific phrase. Can be set automatically. In the above example, by setting the system to use the syllable-based initial code, and entering only "securities information", the simple code for "securities information" can be automatically designated as "9196".

In the case of English, it is said that capital letters can be used to highlight and display the alphabet intended to be used as a simple code. Therefore, the simple code designation method can be pre-designated to use uppercase letters as simple codes, and when entering "DaTe ToNignt", "3886" corresponding to the uppercase letter "DTTN" can be automatically designated as a simple code, or "ToNignt ShoW" When inputting, "8679" corresponding to the capital letter "TNSW" can be automatically designated as a simple code.

6.7 Abbreviated input method and parallel input method of phrases using simple codes

When entering a simple code (the initial code is a special case of the simple code, it is considered to be included in the simple code unless otherwise noted), the system (client-side system or server-side system) recognizes it as a phrase corresponding to the simple code. It is possible to process. Therefore, it is natural that if a phrase corresponding to a specific simple code is recognized and shown to the user again, it can be used for inputting a word.

In fact, in the foreign alphabet input method, an index with "all related simple code" for each word is stored in the terminal (client system), and when the user enters the code, the corresponding word is displayed according to the priority of each unit and the target word The character input system is implemented by making it possible to confirm. For this, you can refer to two Internet sites, http://www.tegic.com and http://www.zicorp.com. For convenience, this method will be referred to as "the whole association shortened input method" or "foreign method" in the present invention.

Comparing the method of Tegic and Zi with the alphabet input method on the keypad suggested by the applicant, the applicant's alphabet input method is to assign a unique code in alphabetical units, and to input the target alphabet or target phrase by the full code. The foreign method mentioned above is to assign a simple code associated with the whole word unit and allow the target word to be input by the simple code.

The disadvantage of foreign methods is that only predefined words can be entered by assigning a code in units of words. In case of having the same code while being a different word, target using a toggle button or a move button to input a word that is not used frequently. It is difficult to input a word by selecting and confirming a word, that a word other than the target word may appear temporarily during input, and that it takes up a lot of storage capacity of the system and requires a lot of cost to implement it.

Here, it is pointed out that a simple code (partly related or all related) is assigned to a common phrase (a concept including all common words or common phrases), and the target phrase can be input using a simple code. It goes without saying that the simple code for the common phrase may be predefined in the system and provided to the user, or it must be arbitrarily designated by the user. Or, the user should be able to arbitrarily modify the simple code defined in the system. What the user can arbitrarily designate has the advantage that the user can easily know the simple code value for a specific common phrase.

In the present invention, a method of inputting a target phrase using a simple code (including all of the partial related simple code, all related simple code, and initial code) is referred to as a "shortened input method" for convenience, and a method of entering the target alphabet by full code. For convenience, it is referred to as "full input method" in contrast to the shortened input method. In addition, as described below, the shortened input method and the full input method can be applied in parallel. For convenience, the shortened input method and the full input method can be applied in parallel. Let's call it "input method".

Among the full input methods in which a unique code is assigned in alphabetical units and the target alphabet can be entered by entering the code, the ambiguity caused by using the repetitive selection method in particular is called "first-order ambiguity" or "alphabet ambiguity" for convenience. It should be. On the other hand, in the method of assigning a code to all words as in a foreign method and allowing the target word to be input through this code, there is an ambiguity that there are several different words for the same code. It will be referred to as "ambiguity" or "phrase ambiguity". In the present invention, simply ambiguity means primary ambiguity.

A specific input value is primarily interpreted as a simple code (that is, a shortened input method is applied firstly or a shortened input mode is applied as a basic input code), and if there is no simple code corresponding to the input value, it is secondly converted to a full code. Scenario configuration such as recognition (i.e., applying the full input method secondarily) can be configured, and on the contrary, the input value is primarily checked to see if the full code is formed (i.e., the full input method is applied first or the basic input mode). Full input mode is applied), and if a full code cannot be formed, it is recognized as a simple code (that is, a shortened input method is applied secondarily). Firstly interpreting the input value as a simple code can be seen as applying the "shortened input mode" as the basic input mode. Conversely, firstly interpreting the full code as the basic input mode is "full input mode". It can be seen as applying. For users who mainly use commercial phrases in character input, it is desirable to apply the shortened input method first (that is, use the shortened input mode as the default input mode), and those who do not use the full input method first ( That is, it would be desirable to use the full input mode as the basic input mode.

Here, when the basic input mode is set to the full input mode, the input value is primarily regarded as a full code and interpreted, so even when a simple code is input, the input value can form a full code, and the user wants A word other than the target word may be input. For example, in the case of applying the reference repetition selection method as the full input method in Fig. 4-2, the simple code of the word "corn" is set to "877" (the syllable-based initial code is used), and when entering this Since it is regarded as a full code, it can be recognized as "female". This occurs when the initial letters of the 2nd and 3rd letters correspond to the same button, such as "corn", "corn", "infinity", "warr", "excellent", "wajangchang", and "woodangtang". Conversely, when the short input mode is set as the basic input mode, the input value is primarily regarded as a simple code and interpreted, so that even when a full code is input, it can be recognized as a word other than the target word. That is, this is the ambiguity between the simple code and the full code, which will be referred to as "third-order ambiguity" for convenience.

This third-order ambiguity can also be overcome by a toggle method or a method of selecting from a list similar to the existing method. Alternatively, there may be other methods, such as allowing you to switch from full input mode to shortened input mode or from shortened input mode to full input mode before entering an input value that may cause such ambiguity. It is possible to input one word of katakana in hiragana mode or one word of hiragana in katakana mode by placing a "ah/ah" control as suggested in the applicant's earlier application and selecting it by placing a word-based Hiragana/Katakana conversion control. It's similar to making it happen. For example, if the default input mode is the full input mode, the system recognizes the input value as a simple code from the beginning and corresponds to the input value by referring to the index for the input value entered after selecting it with the "short/full" control. The target word can be provided to the user. Even when the shortened input mode is used as the basic input mode, the input value input after selecting the "shortened/full" control can be recognized and processed as a full code from the beginning. Likewise, the "shortened/full" control may be pre-inputted or post-inputted for the target word, but in this case, it would be convenient to pre-input it.

When applying the parallel input method, the determination of whether the input value is a full code or a simple code can be made in units of words as if referring to the index in order to remove the first ambiguity, and whether the input box is a full code in the middle of input as follows. It may be determined whether it is a simple code.

When the full input method is set to the basic mode and the parallel input method is applied, the input value is determined as a simple code at the point where it is judged that the full code cannot be formed by examining whether the input value forms a full code each time the code is input. Thus, the efficiency of the parallel input method can be doubled by referring to the simple code index and showing the corresponding phrase to the user. In the case of applying the parallel input method with the shortened input method as the basic mode, the moment when it is confirmed that there is no word matching the input value in the index by comparing the input value and the index each time each code is entered, this is the preset full input method. It can be processed by judging by the full code of. This means that the third-order ambiguity occurring in the middle of the input can be removed at the beginning of the input by applying the rules in each full input method. This can be applied to the case of using an alphabetic input method not suggested in the previous application as a full input method. For example, based on the full input method (standard repetition selection method, partial selection method) suggested in the previous application, for example:

In the case of Korean, for example, when the reference repetition selection method is applied based on Fig. 4-2 as the full input method, the second input value and the third input value of all syllables by the full code must always have the same value. If this condition is violated, the input value can be determined as a simple code and processed. When it is allowed to treat a pair of consonants as a combination of basic consonants, the criteria for judging accordingly can be applied. This is applicable in all cases where the standard iteration method is applied.

In addition, in all languages, when applying the partial full selection method as the full input method, two input values correspond to one alphabet, and the second input value is limited to the first input value among the two input values. . For example, in the case of English, if only the left and right straight line combination is used as shown in Fig. 1-1, if the number is not selected as the partial full selection method, the buttons in the first row ([1], [2], [3] ) Is used as the first input value corresponding to one alphabet, the value that can come as the second input value is also the button in the first row ([1], [2], [3]). Similarly, if [2]+[1] is entered and then the second row of buttons ([4], [5], [6]) is pressed again, the next possible value to form the full code is also the second row. It is one of the buttons ([4], [5], [6]). As soon as the input value violates this, the system regards the input value as a simple code, and a word corresponding to the simple code can be recommended to the user according to priority. If the partial whole selection method is applied to Fig. 4-2, only the [1] or [2] button is the next button that can come to the input of the first [1] button to form a full code. If this is violated, it is determined that the input value is a simple code rather than a full code, and a target word corresponding to the input value may be recommended to the user according to priority by referring to the index. As shown in Fig. 1-3, when four alphabets of P, Q, R, and S are assigned to the [7] button, as pointed out in the previous application, one of the four alphabets will be placed on the grid forming the upper and lower adjacent Even in this case, if the [7] button is pressed to form a full code for one alphabet, the next button is the button in the third row ([7], [8], [9]) or up and down. Since only the adjacent combination button (button [4]) can come, if it is violated, the input value can be processed as a simple code. This is applicable to all languages when applying the partial selection method suggested in the previous application.

In the case of Fig. 4-5, only one basic consonant per button is assigned, so when a syllable-based initial code that can be used universally in Korean is used as a simple code, even when the shortened input method and the full input method are applied in parallel. There is a good feature that allows input without car ambiguity. In other words, if the user inputs the syllable-based initial code when applying the parallel input method, the input value cannot achieve the full code from the second input (when inputting the aspirating sound or aspirating sound by the control processing method), so the index of the simple code is It is possible to search and recommend appropriate words according to priority to the user. The same is true for full code input.

As an example above, when applying the parallel input method, it is one of the "cores" of the present invention to be able to determine whether an input value is a simple code or a full code during input. This applies not only to the case of using the full input method suggested by the applicant, but also to the case of using another full input method. In particular, the full input method proposed by the applicant has a good characteristic that it is easy to know whether the input value constitutes a full code when applying the parallel input method as in the example above.

In addition, as mentioned in the applicant's earlier application, the interpretation of the simple code or the full code may occur on the client side or the server side. In order to look up the index to overcome the primary ambiguity (alphabetic ambiguity) in the previous application, the scenario of referring to the server-side index secondly by referring to the index on the client side is also used in interpreting the simple code or the full code. Can be applied. Conversely, it is possible to refer to the server-side index primarily and to the client-side index secondarily. Furthermore, the input value is first interpreted as a simple code, but firstly the index on the client side is referenced, and the server side index is secondly referred to, and if the simple code for the input value is not searched, it is interpreted as a full code again. However, it is possible to analyze primarily on the client side, and if there is no such analysis function on the client side, it is possible to interpret it on the server side secondarily. As another example, the input value is primarily interpreted as a simple code, but it is also possible to refer both the client-side index and the server-side index to provide it to the user and allow the user to select a target word. In this way, in applying the analysis method (simple code, full code) and the analysis location (client side, server side), similar modifications are possible. That is, in summary, various combinations are possible in the application of the analysis method (simple code, full code) and the analysis location (client side, server side).

The advantages of applying the shortened input method and the full input method in parallel are as follows. First of all, since the full input method can be used, the user can input all words even if the words do not exist in the dictionary other than the predefined words, and a simple code for the use of the shortened input method for common phrases is conveniently (partially related). /All associations) can be specified, and the number of input strokes can be significantly reduced by specifying a partial association simple code. In addition, there is an advantage of assigning word-based initial codes not only for words but also for phrases. However, since foreign methods use a method using a word-by-word index for input of all words, a simple code related to the whole has to be used to minimize the case where the same code is assigned to different words.

In addition, the system must have a "index" that holds a specific phrase and the code value for that phrase, which requires much less storage space than the foreign method that has "index" for every word. do. In order to eliminate ambiguity, this "index" must have a "index" for correct words or a "index" for wrong words in order to eliminate ambiguity. Can be used as

Since it is consonants that have the phonetic value of a specific word in all languages, the technique of extracting consonants to create abbreviations has already been widely used. In the case of English, for example, the consonant "CPT" that has a phonetic value from "captain" among military terms is extracted and used as an abbreviation, "PVT" is used as an abbreviation in "private", and "SGT" in "sergent" Is used as an abbreviation, "SSG" is used as an abbreviation in "staff sergent", SFC is used as an abbreviation in "sergent first class", and so on. Of course, the examples of "captain" and "private" each consist of two syllables, but the extracted consonant as an abbreviation here can be viewed as a consonant representing each syllable. Therefore, in the case of "captain", "278" associated with "CPT" can be designated as a simple code.

In addition to reducing the input effort, it is of great significance that the shortened input method can be applied by arbitrarily designating a partial associated simple code for a common phrase based on a syllable. Phonetically, syllables are defined as "psychological entities." Also, it is a consonant that has a phonetic value in a syllable. If only the vowel "AAI" is extracted from the example captain, it is almost impossible to infer the captain. However, by extracting the consonant "CPTN" or "CPT", you can easily deduce the captain. If you remove vowels for each word from a sentence in English and list only consonants, you can usually infer the original sentence. That is, the use of a partially-associated simple code in association with each consonant, which is a subject of a syllable, means that the user can naturally adapt to the shortened input method, and that it can provide convenience to the user.

In particular, it is common to use abbreviations in the English-speaking world, and in the case of a listed company name, a certain number of abbreviations are designated, so a simple code can be used based on this abbreviation.

The advantage of allowing a user to designate a simple code (partial association, all association) for a specific phrase conveniently allows the user to easily memorize the code value for a common phrase. Furthermore, if a user needs only a small fraction of the common phrases (for example, using only 10 or less common phrases), the code related to the alphabet of the common phrases is not necessarily assigned, but only 1 for each phrase. Simple codes such as, 2, 3,... etc. can also be assigned.

6.8 Grouping of simple code/correspondence phrases and designation of search scope

If a simple code is designated for a large number of phrases, there is a possibility that a lot of redundancy may occur. The phrases corresponding to the simple code are grouped to search for the simple code only for a specific phrase group, thereby ambiguity between simple codes (secondary ambiguity). Can be reduced. A phrase does not have to belong to only one group, but may belong to multiple groups.

For example, simple-named phrases are grouped into groups such as listed company name, city name, commercial phrase,..., and the common phrase group is divided into subgroups such as social field, political field,... Can be grouped. In this example, two-stage tree-type grouping is presented, but a tree-type grouping is possible in three, four, or more stages. If the user (or the system) limits the search scope of the simple code to the listed company name group, when entering a specific simple code, the system searches for a named phrase corresponding to the simple code entered only in the category of the listed company name group. It can reduce ambiguity. Similarly, if the search range is a common phrase, the search range can be made to include all subgroups below the common phrase group. If a social field group among the common phrase groups is designated as the search range, only the lower group (in the tree-shaped group structure) including the social field will be the search range.

6.9 Use of relay server

The interpretation of the simple code can be done on the client side or on the server side, and the simple code (including full code in some cases) is dedicated to decryption and provides the phrase corresponding to the simple code to the client side or other server side You can have a relay server. See FIG. 6-1. In addition, in Fig. 6-1, if the client side first decodes the simple code and fails to interpret the phrase corresponding to the input simple code, the second interprets the phrase corresponding to the simple code input from the relay server, and the interpretation fails. In addition, it is possible to interpret the phrase corresponding to the simple code input from each server thirdly. The tertiary simple code decoding server (referred to as a "tertiary server" for convenience) becomes a server on which an application using an input simple code or a phrase corresponding to the simple code is installed.

If there is a relay server, even if the tertiary server needs a phrase other than a simple code, the user inputs the simple code, and the tertiary server does not store the simple code and the phrase corresponding to the simple code. It is possible for the server to interpret the simple code input from the user by the relay server and deliver the phrase corresponding to the simple code to the tertiary server.

Each time each code value of the simple code is input, the index in which the phrase corresponding to the simple code is stored may be searched and the feedback may be provided to the client side or each server side, or the feedback may be provided in word units.

6.10 Classification of word units

In the present invention, the word unit means from the beginning of the word to the end of the word. This can be identified through a combination of all the elements (word start, space, mode change, enter,...) that can differentiate between words and words. For example, blank to blank, blank to mode conversion, etc. can identify that a word has been input through word start ~ word end. Giving feedback in word units can be sufficiently implemented through a language that supports the current network environment.

6.11 Download of simple code/correspondence phrase

Furthermore, the simple code on the server side and the phrase corresponding to the simple code can be downloaded to the client side without the user directly inputting and saving the phrase.

The units to be downloaded can be downloaded in units of phrases one by one, or can be downloaded in groups of phrases (tree-structured groups) as described above. If you select the upper group, you can download the lower group. The tree structure of the phrase group on the server side can be maintained and downloaded, or the phrases belonging to the group and subgroups can be downloaded as a group designated by the user on the client side. If there is a relay server whose main function is to decode simple codes, the relay server can also take charge of this function.

7. Input of symbols

As suggested in the previous application, it was explained that the native language alphabets can be placed in the "order close to the standard grid", followed by numbers and English alphabets. When applying the standard repetition selection method, it is also possible to place them in the order close to the standard grid. Explained that alphabets and numbers can be selected. Similarly, in applying the subsequent control processing method, not only the native language alphabet belonging to a specific button, but also numbers and English alphabets can be entered through the subsequent control processing method.

In the present invention, we go one step further and present a method for efficiently inputting various symbols without displaying on the keypad (that is, by a hidden control processing method) that allows input by displaying on the keypad in the previous application. do.

In other words, among the grids in which controls were placed in the previous application, "symbol control" is placed on an appropriate grid, and symbols are input by combining a symbol control and a button that can mean a symbol (a button other than the control button). Here, as an example of a button that can mean a symbol, in the case of a period, it becomes the [5] button because it can be easily reminiscent of "ㅁ" in the period.

For example, in the Korean embodiment (Fig. 4-2) of the invention contents of the previous application, the symbol control can be placed in a grid position that can be selected by pressing the [*] button twice in succession. In other words, a relationship between the representative alphabet and the subsequent alphabet is established, such as a (representative alphabet), ㅋ (2nd), symbol (3rd), and so on. In the case of control line input, when "period" is input, ㅁ = {symbol} +ㅁ = [*]+[*]+[5]. When input after control, ㅁ = ㅁ+{symbol} = [5]+[*]+[*]. If the symbol control is placed in a grid position that can be selected by pressing the [*] button 3 times, you can add the inputs of the [*] button one by one in the example.

If there is only one symbol control, only about 10 symbols can be entered, even if one symbol is given to each of the 10 number buttons. An example of assigning the meaning of a symbol to each button is as follows.

[1] button:? Giving the meaning of ("ㄱ" is arranged, but the shape is similar to ?)

[2] button:! The meaning of ("ㄴ" is arranged, but the first letter of "exclamation mark" is the same)

[3] Button: Meaning of $ ("ㄷ" is arranged, but the first letter of "Dollar" is the same)

[4] button: ...

[5] button:. Meaning ("ㅁ" is arranged, but the first letter of "period" is the same)

[6] Button: The meaning of * ("ㅂ" is arranged, but the first letter of "asterisk" is the same)

[7] button: The meaning of, ("ㅅ" is arranged, but the first letter of "comma" is the same)

[8] Button: The meaning of "("ㅇ" is arranged, but the first letter of "quotation mark" is the same)

[9] Button: Meaning of ~ (the vowel "ㅡ" is arranged, but the shape is similar to ~)

[0] button: Meaning of @ (number 0 is arranged, similar to @)

As above, you can enter a symbol by combining a button that can remind you of various symbols and a symbol control. To give each button the meaning of the symbol, as in the example, the relationship between the local language name/shape of the symbol and the arranged alphabet, or the relationship between the English name/shape and the arranged English alphabet, and the arranged number name/shape and The meaning of the sign can be given by considering the relationship of Since this may vary according to individual preferences, it is not necessarily the same as above, and individuals can be made to (re)set the meaning of the symbol for each button.

Through this, as in the example, frequently used symbols can be treated as if they were a subsequent alphabet belonging to a number button that is easy to associate with. In the above example, the question mark is associated with the [1] button in which "ㄱ" is placed in consideration of the similarity of shape because the period, which is used more frequently than the question mark, starts with "ㅁ".

Likewise, in assigning the meaning of symbols for each button, an English name/shape or a numeric name/shape may be used. The example below can be applied interchangeably with the case of the native language.

[1] button:? The meaning of (the alphabet "q" is arranged, but the first letter of :Question mark" is the same)

[2] Button: The meaning of, ("c" is arranged, but the first letter of "Comma" is the same)

[3] button:. The meaning of ("d" is arranged, but the first letter of "Dot" is the same)

[4] button:! Meaning ("i" is placed, similar in shape to "!")

[5] button: ...

[6] button: ...

[7] Button: Meaning of / ("s" is arranged, but the first letter of "Slash" is the same)

[8] Button:: Meaning (the number "8" is arranged: similar in shape to)

[9] button:! The meaning of ("x" is arranged, which is related to the pronunciation of "eXclamation mark")

[0] button: Meaning of @ (number 0 is arranged, similar to @)

Giving the meaning of symbols based on English can be usefully used even in non-English languages using a keypad marked by mixing English. Also, setting the colon with the similarity of the shape of the number 8 has the advantage that it can be used universally regardless of language. Likewise, comma can also be regarded as a successor alphabet belonging to the [9] button by putting a similarity in shape with the number 9, but this was not the case in the above example.

Just set the symbol control to the appropriate button. In the case of English, if the [*] button in Fig. 1-1 does not have a control for another purpose, select the [*] button 1 tarot symbol control (that is, put the symbol control at the position of the [*] button reference grid). You may. In addition, in the case of European languages in which modified alphabets with subscripts are present, symbol control can be placed at the position of the reference grid of the [0] button or the [#] button. However, in the case of putting symbol control on the [0] button, it is better not to give the meaning of the "@" symbol as in the example above.

If you put the symbol control on the [*] button and apply the input after the control, in the case of English, when entering a colon(:) in Fig. 1-1,: = [8] + {symbol} = [8] + [*] do.

As shown in the example above, when the meaning of the symbol associated with each button is given one by one and the symbol control is placed on only one grid of the control button, only about 10 symbols can be entered. In addition, in assigning meaning to each button, as in the example in English, meanings such as slash, semi-colon, and period may be assigned to the button assigned with "s", but only the meaning of slash, one of them, was given. The meaning of dot is also given to the button assigned with "d", so in the case of exclamation mark inevitably, considering the similarity of shape, the button assigned with "i" has "!" The meaning of was given.

Therefore, by placing a number of symbol controls (for example, symbol control 1, symbol control 2,...), and allowing a control to be selected, a greater number of symbols can be input through the control processing method. For example, "d" gives the meaning of the assigned dot (or gives the meaning of "period" to a button assigned with "ㅁ"), and a comma with a similar shape can be treated as if it were a successor character of a dot. have.

As in the example of FIG. 7-2 in which the symbol control is added to FIG. 4-5, "Symbolic Control 1" can be selected with the [*] button 3 strokes, and when the input after control is applied, dot = [3]+ {Sign1} = [3]+[*]+[*]+[*], comma = [3]+{sign2} = [3]+[*]+[*]+[*]+ It becomes [*]. Looking at this from the point of view of the chain-type subsequent control processing method, comma = dot+{next} = dot+[*} = [3]+[*]+[*]+[*]+[*]. If it is decided not to input the aspirated sound according to the control processing method (that is, assuming that there is no aspirated sound control), it is natural that "Symbol Control 1" is selected for the [*] button 2 stroke (skip control processing). Similarly, colons and semi-colons that are similar in shape are regarded as successive characters assigned to the same button, and can be entered by the control processing method. Similar tricks can be applied to other symbols.

In the case of using two symbol controls such as "Symbol Control 1" and "Symbol Control 2", you must give the meaning of the symbol to each button and remember it, and there is a limit to the number of symbols that can be entered. do. Therefore, it is possible to input more symbols by grouping symbols in the same way as grouping dot and comma, colon and semi-colon, and having multiple symbol controls.

It is desirable that the grouping of symbols can be performed at the user's convenience. In the present invention, an example of symbol grouping that can be used in general is shown. First, it is possible to set the transformed form of dot as a group based on the form of various symbols. For example, dot(.), comma(,), colon(:), semi-colon(;), quotation mark("), ..., question mark(?), exclamation mark(!),... It is possible to group like .. This is a grouping of symbols in the form of a dot, that is, in the form of "0 dimension", where? And! Have both a 0 dimensional shape and a 1 dimensional shape at the same time, so a 0 dimensional shape (dot). As mentioned in the previous application, the frequency of use, etc., can be considered in determining the subordinate ranking of the group, but it would be better to allow the user to set it as well. When the number of symbols is large, it would be convenient to enter the symbol control afterwards, and in a terminal with a display window, you can see that the symbol changes as the control button is pressed.

Associating the grouped dot-shaped (0-dimensional) symbol to a specific button can also be set at the user's convenience. For example, if the symbol that can represent a group and is the most frequently used symbol is dot, it can be regarded as a successor alphabet belonging to the [3] button containing the "d" of the dot. In the example of FIG. 7-1 in which the symbol control is added to FIG. 1-1, when the symbol control button is set as the [*] button and input after control is applied, dot = [3] + [*], comma = [3] +[*]+[*], colon = [3]+[*]+[*]+[*], semi-colon = [3]+[*]+[*]+[*]+[*] ,... becomes like this. Or, if it is regarded as a successor alphabet belonging to the [0] button because it is a 0-dimensional shape, it will be combined with the [0] button instead of the [3] button. Alternatively, since the dot form is the most basic form, it can be regarded as a subsequent alphabet belonging to the [1] button.

Next, you can group symbols in the form of a line, that is, in the form of "one-dimensional". For example, slash(/), hat sign(^), question mark(?), exclamation mark(!), round bracket 1((), round bracket 2()), angle bracket 1(<), angle bracket Grouping like 2(>), right angle bracket 1([), right angle bracket 2(]), wave sign(~), minus(-), arrow 1(<-), arrow 2(->),... can do. Also, as described in the previous application, it is necessary to place a subordinate ranking in consideration of the frequency of use, etc., and to associate this with the subsequent alphabet of a specific button, an appropriate button can be set as described above. For example, it is regarded as the successor alphabet belonging to the button [1] or the successor alphabet of the button [5] in which the letter "l" is placed.

Then, the combination of lines, that is, the "two-dimensional" form of symbols, can be grouped into groups. For example, at(@), ampersent(&), asterisk(*), sharp(#), dollar($), won symbol (W+=), yen symbol (￥),..., heart1(♡) , heart2(♥), clover 1(♧), white triangle 1(◁), white triangle 2(▷), white triangle 3(▽),..., black triangle 1(◀),..., ☏, You can group them like ☎, ☜, ♨, etc. Also, the sub-ranking can be placed in consideration of the frequency of use, and you can choose an appropriate method to associate it with a specific button. However, you can relate it to a button other than the button with which the symbol of the 0-dimensional shape and the symbol of the 1-dimensional shape were associated with the previous one.

As above, when grouping symbols into three groups of 0-dimensional, 1-dimensional and 2-dimensional forms (this is called “three large groups” for convenience), there is an advantage that only three associated number buttons need to be remembered, but symbols that are not used frequently In the case of input, there is a disadvantage of having to press the control button several times. Therefore, an example of subdividing groups slightly (this is called "subgroup" for convenience) is as follows.

First, in a two-dimensional symbol group, it is divided into a symbol group that forms a combination of lines (ex. *, #, %, ...) and a symbol group that forms a single closed curve (ex. ◁, ◀, ...). I can. In addition, in a group, symbols that form a picture such as ☏, ☎, ☜, ♨, ... can be put into separate groups. Again, you can leave it as a follow-up alphabet that belongs to the appropriate button. If these groups are placed separately, these symbols may or may not be excluded from the preceding symbol group, and this is the same for other cases.

Next, one-dimensional or two-dimensional symbols used in mathematical expressions, ie +, -, *, /, root(√), sigma(∑), integral(∫),... You can put it in groups. Again, you can leave it as a follow-up alphabet that belongs to the appropriate button.

In addition, symbols that can indicate directions, ie →, ←, ↑, ↓, ↗, ↙, ↖, ↘, ◁, ▷, ◀,... can be divided into groups. Again, you can consider the subsequent alphabet in relation to the appropriate button.

In addition, various parentheses, that is, (,), [,], {,}, <,>,..., which can form another group relatively appropriately, can be placed as another group. Also, when grouping in parentheses, the left parenthesis and the right parenthesis may be grouped together.

3 In the case of not having only large groups, but in the case of subgroups so that symbols can be entered by it, it was said that the alphabet belonging to the subgroup may or may not be left in the third group. Even if it is placed in the third group, subordinate rankings are subordinated as much as possible. Will have to be put on.

When the above symbol grouping is applied to FIG. 1-1, an example in which a group of each symbol is regarded as a subsequent alphabet of a specific button is as follows. The 0-dimensional symbol group is regarded as the successor alphabet belonging to the [0] button, the 1-dimensional symbol group is regarded as the successor alphabet belonging to the [1] button, and the two-dimensional symbol group is the successor character belonging to the [2] button. Regarded as an alphabet, the symbol group in the form of a single closed curve among the two-dimensional symbol groups is regarded as the subsequent alphabet belonging to the [8] button, and the symbol group in the picture form among the two-dimensional symbol groups is the subsequent alphabet belonging to the [7] button. Regarding the mathematical symbol group as the subsequent alphabet belonging to the [6] button, the direction symbol group as the subsequent alphabet belonging to the [3] button, and the parenthesis symbol group as the subsequent alphabet belonging to any button among the remaining numeric buttons. Can be considered. As described above, this is only an example in associating a preference group with each button, and it can be set at a user's convenience.

In summary, the symbol can be regarded as a subsequent alphabet belonging to a specific button, and can be grouped into 3 groups (0 dimension, 1 dimension, 2 dimension), or slightly further subdivided into 10 or fewer groups. It is one of the key points of the present invention to show that most of the symbols can be input by grouping. In addition, when each group of symbols is regarded as the successor alphabet belonging to a specific button, the symbol is not displayed on the keypad and is concise by considering it as the successor alphabet belonging to the button associated with the group of symbols, such as name, dimension, shape, etc. One of the key points of the present invention is to be able to use the "hidden type follow-up control processing method" while maintaining the alphabetical arrangement.

In the present application, the [*] button or an arbitrary button among the upper and lower left buttons is mainly used as a control button for symbols, and the [#] button can be used as a subsequent control button for numbers and English alphabets. For example, if the [#] button is already being used as a subsequent control button, you can additionally place controls for numbers and English letters on the available grid on the [#] button. In this case, too, in the selection of the control, as mentioned above, the control that cannot be combined with the representative alphabet can be skipped so that the next available control is selected.

8. How to use the move button

8.1 Use of the move button as a control button

In the earlier application, it was said that the control button on which various controls are arranged can be placed on an arbitrary button in the 4*3 keypad, or on a separate button other than the 4*3 keypad. And in the earlier application, especially in languages with a large number of alphabets and a large number of modified alphabets, you may have experienced a lack of buttons to be used as control buttons in the 4*3 keypad. In the present invention, it is pointed out that the primary function of the left/up/down movement button, which is not used relatively frequently in the character input mode, can be used as the control button mentioned in the previous application and the present invention, and such an example is shown. In other words, when using a separate button outside the 4*3 keypad as a control button in the character input mode, the up/down/left movement buttons are used as control buttons.

8-1 shows a button of a folder type terminal that is currently typically used. The [i] button indicated by a broken line is a button for Internet access, and this button may or may not exist depending on the terminal. Here, the right shift button is used for blank input, and in particular, in Korean, it is also used as a syllable (character) confirmation button to remove the primary ambiguity. In the menu selection mode other than the text input mode, the up/down/left movement buttons are usefully used as movement buttons for menu selection. However, in the character input mode, the up/down/left movement buttons are not used frequently, and in particular, the up/down movement buttons are not used frequently. For convenience, the up/down/left movement buttons are combined to be called "up/down/left movement button" or "up/down/left button", and the up/down movement button is called "up/down movement button" or "up/down button". The same trick is used when referring to only the moving button in one direction.

8.2 Placement at the bottom of the move button

First of all, these upper and lower left buttons are usually placed above the number buttons. However, in order to use these buttons as buttons for entering various alphabets in the character input mode, it is useful to place them at the bottom of the 4*3 keypad along with the [*] and [#] buttons that are mainly used as control buttons. Can be seen. 8-2 and 8-3 illustrate this. However, it is not necessary to do this, and for convenience, the example of the present invention will be described as an example in which the move button is disposed under the 4*3 keypad.

Here, it can be seen that a 5*3 keypad can be configured by combining the 4*3 keypad and the up and down left buttons. This means that when applying the partial selection method, each button can be used by dividing it into 15 grids of 3x5. Likewise, it is not always necessary to arrange the upper and lower left buttons to configure a 5*3 keypad as shown in FIG. 8-3.

8.3 Arrangement of left or right side of move button

You can also place the up/down/left/right movement buttons on the left or right side of the 4*3 keypad.

In this case, in applying the partial selection method, a 4*4 keypad can be formed by combining a 4*3 keypad and a moving button. 8-4 is an example of a case in which the up/down/left/right movement buttons are provided on the right side of a 4*3 keypad.

This is a trend in that the size of the liquid crystal in the terminal is gradually increasing, and there is an advantage that the size of the liquid crystal of the terminal can be made larger. In addition, it has good characteristics when applying the side battery mounting method in a mobile terminal proposed in the applicant's Korean patent applications 10-2000-0002081, 10-2000-0005671, 10-2000-0067852, and 10-2001-0002137 in parallel.

8.4 Various use cases as control buttons and buttons for alphabet input

In the following, an example of using the move button is given. However, it is not limited to the following cases.

8.4.1 Example of use as a symbol control button

In the Korean example, there was a case where the aspirated sound control and the hard sound control were arranged on the [*] button and the [#] button, respectively. In addition, there were cases where the aspirated control and the aspirated control were placed on the [*] button, the basic vowel control and the expanded vowel control were only placed on the [#] button, and the extended vowel control was placed on the [#] button. In this case, the symbol control is placed on the [*] button or the [#] button, and according to the input after the control button, the aspirated sound, a horn sound, etc. comes first, and then the symbol is selected. The same is true for other languages.

However, if the symbol control is separated and placed on any of the up, down and left buttons, a symbol can be input immediately by combining the button associated with the symbol group and the symbol control button on which the symbol control is arranged. 8-5 is an example in which the primary function of the down movement button is used as a control button for selecting a preference control. In the example of applying the input after control to the 0-dimensional symbol group, dot = [3]+[v], comma = [3]+[v]+[v], colon = [3]+[v] +[v]+[v], semi-colon = [3]+[v]+[v]+[v]+[v],...

8.4.2 Example of use as a vowel element button in Korean

In particular, in the case of using vowel elements (ㅡ, ㅣ, .) in the Korean example in the previous application, there was inconvenience in inputting "ㅎ" by arranging the vowel elements "." and "ㅎ" together. By arranging it on any of the left buttons, this inconvenience can be overcome. If the symbol control is placed on the lower movement button and the vowel element "." is placed on the up movement button, two buttons are used from the up, down, and left buttons. Alternatively, you can put three Korean vowel elements on the top, bottom, and left buttons.

Similar to the symbolic control on the button with the aspirated control, the Korean vowel element "." is located at the reference grid position of any button among the upper and lower left buttons. It is also possible to place symbol controls in an order close to the standard grid. 8-6 is such an example. In this case, the vowel element "." is not used alone, so even if the vowel element and symbol control arranged in the repeated selection method are selected, the vowel element and the symbol control can be selected without ambiguity. In Fig. 8-6, when the [v] button is pressed once, the vowel element "." is selected, when pressed twice, symbol control 1 is selected, and when pressed 3 times, symbol control 2 is selected.

8.4.3 Example of use of subscript control buttons in Japanese

In the case of Japanese as well, when the arrangement of the 50-note chart corresponds to each button, the 2nd, 3rd follow-up controls are placed on the [*] button, and the 4th and 5th follow-up controls are placed on the [#] button (how to assign the first application 3). , Controls for inputting long/voiced/half voiced sounds can be placed on any of the up/down/left buttons. See FIG. 8-7.

8.4.4 Example of use as subscript control button for vowel input in Arabic

In the case of Arabic, controls for processing vowels in the form of subscripts can be distributed and arranged on arbitrary button(s) among the upper and lower left and right buttons.

8.4.5 Example of use as a control button in Thai

In the case of Thai, consonant control and vowel control were not separated, and one control button was used as a subsequent control button. Any of the upper, lower, and left buttons can be additionally used as a control button. Or it can be used as a control button on the guitar.

8.4.5 Use case for short/full switching control button

When the parallel input method is applied, there is a third order ambiguity that occurs between the simple code and the full code. In order to eliminate this, a method of putting a "short/full" conversion control in units of words was proposed. For example, if the full input method is the default mode and the parallel input method is applied, to input a word by the shortened input method, first select the "Shortcut/Full" switch control and enter a blank (right move button), and then simple code. Is to enter. Of course, the order of the blank and "short/full" toggle controls can be reversed. Here, a word-based "shortcut/full" switch control can be placed on any of the up/down/left buttons. Alternatively, a control that functions as a combination of a “shortcut/full” switch control and a blank (right move button) can be placed at the reference grid position of any of the up/down/left buttons. See FIG. 8-8.

If it is assumed that the English alphabet of Fig. 1-1 is arranged on the number buttons of Figs. 8-8, in the state that the basic alphabet input mode is full input mode, enter the simple code "4357" associated with the whole of help, and the word help If you want to enter "~ full code input +[^]+[4]+[3]+[5]+[7]+ [>]+ full code input ~". In other words, since the movement function of the upper movement button [^] is limited and the “short/full” conversion function in word units and the blank function are combined, the moment the [^] button is pressed, the system appears next "[4]+... "Recognizing that this is a simple code rather than a full code, it is possible to recommend the words closest to the input [4] to the user by referring to the index. The word is terminated as soon as the blank button ([>] button) is pressed after the input of [4]+[3]+[5]+[7] is finished. It waits for full code input again. If the [^] button is pressed again after inputting the simple code 4357, the system will also recognize that the word has ended, confirm the help corresponding to 4357, and wait for the input of the simple code again.

In the parallel input method, if only one right move button (blank button) is used, there may be a third order ambiguity that occurs between the full code and the simple code as mentioned in the previous application. In this case, it was necessary to check whether a simple code exists or a promised full code is achieved. However, by putting a button that combines the word unit "shortened/full" mode switching and space, the system can recognize in advance whether the input value is a full code or a simple code, so it is possible to improve the performance of the system by reducing calculations and searches. will be.

8.5 Examples of use of the calculator mode as the increase/decrease/multiple button

Regardless of their position, the four movement buttons can be usefully used as the most frequently used increase/decrease (+, -, x, /) buttons in the calculator mode. It is also possible to mark the button with an increase/decrease sign, but it may not be indicated on the button because the calculator will not be used often compared to the alphabet input. This is because each button will be used as a move button or a control button in the alphabet input mode.

(√3)은 3//2 로 풀어 제(/)버튼을 반복하여 누름으로써 "제곱근"연산자를 선택하도록 할 수 있다. 이외의 이항연산자는 중복하여 출현하지 않으므로 적절한 가감승제버튼에 속한 후속연산자로 두고 후속연산자를 반복선택방법에 의하여 선택하도록 할 수 있다.In addition, it is possible to select the operator that can be used in the calculator by the (hidden type) repetitive selection method by placing it on the add/decrease/multiple button. The operator (binary operator) frequently used in the calculator mode uses a property that does not appear repeatedly. For example, there cannot be a calculation of 2++1. In addition, 2 ⁴ can be solved by 2xx4, and the "square" operator can be selected by repeatedly pressing the win (x) button. That is, it is the same as repetitive selection assuming that the win (x) button has a square (xx) operator as a subsequent operator. Likewise

(√3) can be released to 3//2, and the "square root" operator can be selected by repeatedly pressing the (/) button. Since the other binomial operators do not appear overlapping, it is possible to select the subsequent operators by the iterative selection method by placing them as the successor operators belonging to the appropriate increase/decrease/multiple buttons.

It is also possible to use the addition and subtraction (+, -, /) operators on three of the up/down/left/right movement buttons, and the [*] button for the multiplication (x) operator.

9. Help function activation

Here, in each input mode, functions that are not displayed on the buttons (up/down/left/right) can be displayed on the screen (liquid crystal) to add convenience to use. In this case, there is a disadvantage of consuming a portion of the liquid crystal. Of course, a user who has a function of each operator button does not need to display it while consuming space of the liquid crystal, but it may be very helpful to a user who does not. 8-1 may be referred to, and FIG. 9-1 is an example of a case in which the up, down, left and right buttons are arranged on the right side of the 4*3 keypad as in FIG. 8-4, and are arranged in a similar form.

Displaying the button functions (ie, an operator assigned to a button or a symbol group associated with each button) according to the user's convenience and intention is referred to as "activating the help function" for convenience. Activation of the help function can be made for each mode (eg alphabet input mode, calculator mode), or for necessary functions in each mode (eg number buttons or control buttons associated with symbol groups in alphabet input mode). May be.

Likewise, the function of the control button suggested in the previous application or the numeric buttons related to the symbol group are also displayed on the liquid crystal when the user needs it, so that the user's convenience can be promoted. See FIG. 9-2. 9-2 is an example in which number buttons associated with each symbol group are converted into icons and displayed on a liquid crystal based on the symbol group classification exemplified above. Among the symbols of the symbol group associated with each number button, only the first symbol selected for convenience is added to the number button icon.

10. How to use the delete button

In using the delete button, it can be used as the "final input cancellation" introduced in the previous application. For example, in FIG. 4-5, trying to enter "a", inputting [1]+[*] to enter "ㅋ", but pressing the delete button to cancel the final input ([*]) to return to "a" It can be done. This can be usefully used in the case of repeatedly pressing the control button and inputting a subsequent alphabet. When the cancel button is pressed consecutively, an already known alphabet may be deleted in a conventional manner. For example, if you enter "Kana ㅋ" and press the cancel button once, it becomes "Gana", if you press it again, it becomes "Gana", and if you press it again, it becomes "Go". In the case of Roman characters, "aba.." is entered (the last "a.." is a transformed alphabet consisting of "..+a"), press the delete button once to become "aba", press it again to "ab" If you press it again, it becomes "a". That is, the already formed alphabets are deleted in alphabetical units.

11. Unification of the numeric keypad on the keyboard and the keypad on the phone terminal

It is obvious that the keypad proposed in the previous application and the present invention can be applied to all fields of a phone keyboard type such as a numeric keypad of a mobile terminal or a standard keyboard, or a keypad or door lock configured in software on a screen. In addition, although the numeric keypad provided in the standard keyboard differs in the arrangement of the keypad and the numeric buttons proposed in the previous application and the present invention, it is apparent that the arrangement on the keypad buttons in the prior application and the present invention can also be applied to a keypad provided in the keyboard. For example, in the previous application and in the present invention, the alphabet arranged on the [1] button is placed on the [1] button of the numeric keypad provided on the keyboard, and then arranged in the same manner to input the alphabet, use simple codes, and memorize various codes. It can be used as a dragon.

However, in order to reduce confusion and add convenience to use, in constructing the numeric keypad of the keyboard, the numeric arrangement of the telephone keypad can be utilized. That is, in the numeric array of the numeric keypad of the keyboard, as in the keypad of a telephone, buttons [1], [2], and [3] are placed on the first row of buttons, and [4], [5] are placed on the second row of buttons. Put the buttons [6] and buttons [7], [8], and [9] on the button in the third row. In addition, you can have [*] buttons and [#] buttons as on the phone's keypad.
