Technical Field
The invention relates to the technical field of character input methods, in particular to an input method and a processing terminal based on character characteristics.
Background
In the current input method, input is rarely carried out according to character characteristics, so that the efficiency of inputting characters is not high, and the coincident code rate is high. For example, in the existing input method, in the process of inputting the first character to the last character and obtaining the final target character, the possible combination number of each input character is huge, resulting in a large number of combined characters, and the user needs to select the target character from a large number of combined characters to complete the input, resulting in low input efficiency, i.e. obtaining the target character which the user needs to input may need to perform a plurality of operations or select from a large number of combined characters. For example, in the current common keyboard layout input method of the "squared figure" layout of the mobile phone, a user clicks each keypad, 3-4 characters are corresponding to each keypad, when the user clicks a plurality of keypads (for example, 4 keypads) to obtain a large number of combined characters, in addition, only when the user stops clicking the keypads and selects the number of the combined characters, the character length of the combined characters can be determined, which causes a large calculation amount of possible combined characters in the process of inputting the characters, and the user needs to select from a large number of combined characters, which causes input efficiency. Meanwhile, the number of the obtained combined characters is large, and the coincident code rate in the same input process is high.

Detailed description of the preferred embodiments
The invention will be further described with reference to the accompanying drawings and specific embodiments:
example one
As shown in fig. 1 to 5, an input method based on character features includes the following steps:
step 1: dividing the characters into a plurality of groups of character groups according to a preset rule, wherein each group of character groups at least comprises one character, and each group of character groups is represented by a corresponding transverse characteristic region. That is, each lateral feature region characterizes a corresponding number of characters.
Preferably, the transverse feature regions are parallel to each other, so that the transverse feature regions do not intersect, and the transverse feature regions characterize the character.
Preferably, the preset rule is grouping according to the height of the characters, and the character height refers to the height of the position occupied by the characters input by the computer. That is, each lateral feature region characterizes a number of characters of the same character height.
As shown in fig. 5, a schematic diagram of heights of the pinyin letters and the 26 english letters (also representing heights of the pinyin letters or the english letters commonly written in the art) occupied during the calculation and input process, the pinyin letters and the 26 english letters can be divided into three types according to the heights of the characters, and a character group with a character height of 1 unit includes 13 characters, specifically, "a, c, e, m, n, o, r, s, u, v, w, x, z"; the character group with the character height of 2 units comprises 11 characters, specifically, the characters are 'b, d, g, h, i, k, l, p, q, t, y'; the character group with a height of 3 units comprises 2 characters, specifically "f, j", wherein when the character "f" is referred to a handwritten English-like format (such as "f"), the height of the character is 3.
According to the chinese pinyin scheme, in the chinese pinyin input method, after an initial (i.e., an initial character) is input, characters that can follow the initial and can form legal characters with the initial have "a, e, g, h, i, n, o, r, u, v", where the character "v" represents a chinese pinyin
。
Therefore, preferably, the character set "a, e, g, h, i, n, o, r, u, v" is divided into 3 character groups, the first character group is "h, i, v", the second character group is "a, e, n, o, r, u", and the third character group is "g". Correspondingly, each character group corresponds to one lateral feature region.
Wherein, each character in the second character group has a character height of 1 unit; the character height of the first group of character groups is 2 units, each character in the first group of character groups is 2 units of height occupying a reference line and above the reference line, the reference line is a horizontal line at the position of the character with the character input height of 1 unit, the horizontal line is taken as the reference line, for example, three horizontal lines in fig. 5 are the reference lines, and the characters occupying 1 unit are all in the reference line; the third group of characters has a character height of 2 units, and each character in the third group of characters has a height of 2 units occupying the reference line and below the reference line.
The grouping has the advantages that the user can form a memory habit with high character height according to the accumulated handwritten Chinese character behaviors all year round, can quickly distinguish each grouped character group, is convenient for the user to quickly select corresponding characters from each group of character groups, reduces the learning cost, improves the input efficiency and reduces the coincident code rate.
The horizontal characteristic region is a graphic of any shape, preferably a graphic formed by a straight line or a curved line or a straight line band or a curved band, or any other shape, which characterizes and displays characters, and is not particularly limited.
Step 2: a plurality of longitudinal feature areas are preset, each longitudinal feature area represents the character length of the combined character, and the character length refers to the number of characters in the combined character. Preferably, the longitudinal feature areas are parallel to each other, so as to ensure that the longitudinal feature areas do not intersect.
Any longitudinal characteristic region is intersected with any transverse characteristic region only once, namely the first longitudinal characteristic region is intersected with any transverse characteristic region, and the first longitudinal characteristic region is intersected with the same transverse characteristic region only once.
Preferably, the respective position of each longitudinal feature region further comprises displaying a numerical value of the character length corresponding to the longitudinal feature region, preferably directly above the longitudinal feature region. The longitudinal feature areas are sequentially arranged according to the character length in a position sequence, for example, from left to right or from right to left in a sequence from small to large in the character length.
As shown in fig. 2, a numerical value "2" immediately above the leftmost longitudinal feature region indicates that the character length of the combination character of the longitudinal feature region is 2.
Preferably, a closed region formed by taking the intersection position of the longitudinal feature region and the transverse feature region as a central point is used as an intersection region, and the intersection region may only include one point of the intersection position, that is, the intersection region is equivalent to the intersection position. The intersection area is used for determining possible input combined characters according to the character represented by the corresponding transverse characteristic area and the character length represented by the corresponding longitudinal characteristic area, and the combined character selected by the user is used as a target character needing to be input.
Preferably, the intersection area is a closed area formed by a circle or a rectangle or a diamond or other shapes, and is not particularly limited. As shown in fig. 4, the intersection region formed by the second longitudinal feature region and the second transverse feature region is circular, and similarly, the intersection region formed by the third longitudinal feature region and the second transverse feature region is circular.
It should be noted that the intersection area may be completely substituted for the intersection position, and the difference between the intersection position and the intersection position is that the intersection position represents a point, which does not occupy an area, and the intersection area occupies a certain area.
And step 3: acquiring a signal for completing an input character, wherein the input character is used as a first character or a first half character string of a combined character, when the input character is one, the input character is used as the first character of the combined character, when a plurality of input characters are provided, the input character is wholly used as the first half character string of the combined character, namely, the input character is used as a first character of a target character or a character string of the foremost part, for example, the input character is 'hu', the combined character 'huang' is used as the target character, and 'hu' is used as the first half character string of the combined character.
And 4, step 4: the input operation signal is obtained, and is an operation signal for inputting a character by a user, and is preferably a slide input signal or a touch click signal on a touch screen or a click signal of a mouse operation or other operation signals, which is not particularly limited. For example, on a touch screen of a smart phone, a signal generated by a slide operation or a touch click operation is used as an input operation signal for inputting a character, and a PC end can complete an output operation of the character by clicking with a mouse.
And acquiring the intersection positions of the intersection of each longitudinal characteristic region and each transverse characteristic region reached by the input operation signal in sequence until the user selects the combined character and finishes character input.
According to the intersection positions reached by the input operation signals in sequence, finding out that the characters represented by the transverse characteristic areas corresponding to the intersection positions can follow the first character in sequence and form legal characters of combined characters together with the first character, namely, the combined characters are legal characters, namely, characters or character strings representing specific meanings, target characters to be input are selected from the combined characters, namely, the selected combined characters are used as the target characters, and character input is completed.
That is, in the composite character, from left to right from the first character, except for the first character, the character positioned at the front corresponds to the character represented by the lateral feature region corresponding to the intersection position where the input operation signal arrives first, and the character positioned at the rear corresponds to the character represented by the lateral feature region corresponding to the intersection position where the input operation signal arrives later.
As shown in fig. 2, the input operation signal reaches a first intersection position where the longitudinal feature region representing a length of 2 characters and the lateral feature region representing a character "h, i, v" intersect, and a second intersection position where the longitudinal feature region representing a length of 3 characters and the lateral feature region representing a character "a, e, o, u, r, n" intersect. Any of the possible formed combination characters, any of "h, i, v" immediately follows the first character, any of "a, e, o, u, r, n" being in the last position. Therefore, legal combined characters can be formed by "zhe, zha, zhu", only the character h of the 3 characters "h, i, v" corresponding to the first intersection position can follow the first character z and may form 3 characters in length, and the characters "a", "e", "u" of the 6 characters "a, e, o, u, r, n" of the pronunciation of the second intersection position can follow the character string "zh" and form legal characters, so that the obtained combined characters include 3 characters. Obviously, before the character "a" or "e" or "u" is preceded by the character "h", the corresponding input operation signal reaches the intersection position corresponding to the transverse feature region where the character "h" is located, and then reaches the intersection position corresponding to the transverse feature region where the character "a", "e" or "u" is located.
It should be noted that determining the combination character only requires obtaining the transverse feature region through which the input operation signal reaches the last intersection position and the input operation signal passes, that is, the middle character of the combination character except the first character and the last character (i.e., the last character) only requires determining that the input operation signal passes through the corresponding transverse feature region, and does not require passing through each intersection position. It is only one of the preferable ways to determine that each character of the combined character passes each corresponding intersection position by inputting the operation signal.
Illustratively, as shown in fig. 3, the user slides from the completion of inputting the first character "z" to a path a1 formed by the intersection position of the second transverse feature region and the second longitudinal feature region after sequentially sliding through the first transverse feature region between the first longitudinal feature region and the second longitudinal feature region, and the combined character formed by the path a1 includes "zhe, zha, zhu".
Similarly, after the user finishes inputting the initial character "z", the user slides the initial character "z" sequentially through the first transverse feature region between the second longitudinal feature region and the third longitudinal feature region and then slides the initial character "z" to a path a3 formed by the intersection position of the second transverse feature region and the second longitudinal feature region, and the combined character formed by the path a3 also comprises "zhe, zha, zhu".
The combined characters input by the paths a1 and a3 are the same as the combined characters corresponding to the input paths formed by successively reaching the first intersection position and the second intersection position.
If the user slides to the second transverse feature region after sequentially sliding through the first transverse feature region between the second longitudinal feature region and the third longitudinal feature region after completing inputting the first character "z" and does not slide to the path a2 formed by any interaction position, no corresponding combination character exists, and the input is invalid.
Of course, when such an input situation as the path a2 is encountered, the characters corresponding to all the lateral feature regions that pass through in sequence and the combination character that may be formed by the first character may also form a combination character, regardless of the character length, where the combination character includes at least one of the characters corresponding to each of the lateral feature regions, and the character corresponding to the lateral feature region that passes first precedes the character corresponding to the lateral feature region that passes second first. For example, the combined character formed by path a2 includes "zha, zhe, zhu, zhua" regardless of the character length. Of course, when neither the character length nor the order of passing through the transverse feature regions in sequence is considered, the combined character formed by the path a2 includes "zha, zhe, zhu, zhua, zhuan, zhai, zhan, zhao, zhei, zhen, zhou, zhui, zhun, zhuozhong, zhuai".
The characters which can follow the first character refer to that single characters or character strings which can follow the first character are found out according to a Chinese pinyin scheme, a Chinese stroke arrangement rule, an English word arrangement rule or other characters with arrangement rules, which are collectively called character arrangement rules, and form legal characters together with the first character, and the obtained legal characters are combined characters. A single character means that only one character follows after the first character and can constitute a combined character together with the first character, and a character string means that at least two or more characters follow after the first character and can constitute a combined character together with the first character. For example, after the first character is the pinyin letter h, legal characters that can be formed after the pinyin letter h include "he, ha, hu, hui, hao, huan, huang", etc., and correspondingly, "e, a, u", etc., may all follow the single character immediately after the first letter h, and "ui, ao, ua, uang" is a character string. Correspondingly, the character "b" cannot follow the initial letter h.
The input of the first character may be performed on an existing standard keyboard, which may be a virtual standard keyboard, such as a virtual keyboard on a touch screen, or a physical standard keyboard. For example, a keyboard with a "squared figure" layout may be used in a currently-used mobile phone terminal, without specific limitation.
Preferably, the method further comprises the step 5: and when the input operation signal reaches the intersection position, displaying the combined characters at the corresponding position of the currently reached intersection position, wherein all the combined characters form a combined character group.
Preferably, in order to facilitate the subsequent character input, the combined character is not displayed at the position of the transverse characteristic region and the longitudinal characteristic region, so as not to influence the operation of inputting the character. Or at least, the combined character does not display the positions of the transverse characteristic region and the longitudinal characteristic region after the intersection position reached by the current input operation signal, so as not to influence the operation of subsequent character input. As shown in fig. 2, the composite character is not displayed on the three lateral feature areas and the five longitudinal feature areas, or after the input operation signal reaches the second intersection position, the composite character is not displayed at a position behind the second intersection position, that is, at the right side of the second longitudinal feature area.
Preferably, the method further comprises setting a selection area for displaying the combined character and receiving a user selection of the combined character.
Preferably, the selection area is provided in the vicinity of the intersection position.
Preferably, the selection area is arranged in a closed area formed by the transverse characteristic area at the intersection position, the adjacent transverse characteristic area, the longitudinal characteristic area at the intersection position and the adjacent longitudinal characteristic area. As shown in fig. 2, a rectangular region formed by the first longitudinal feature region, the second longitudinal feature region, the first transverse feature region and the second transverse feature region is used as a selection region, and the selection region displays a combined character.
Illustratively, the closed area is circular or oval or diamond or square or other shape, and is not particularly limited.
And generating a first operation signal by sliding or clicking, and when the selection area receives the first operation signal, namely when the user slides to the position of the combined character in the selection area or directly clicks the combined character in the selection area, the combined character corresponding to the position of the first operation signal is taken as a target character to be input, and the input is finished.
The first operation signal and the input operation signal may be the same operation signal or may be different operation signals. When the first operation signal and the input operation signal are the same operation signal, it indicates that the user input character and the selected combination character are continuously completed, and there is no pause operation in the middle, for example, the user continuously slides to generate the input operation signal, and generates 3 combination characters "zhe, zha, zhu", and the user continuously slides to the selection area and selects the combination character "zha" as the target character to be input, and completes the input. The first operation signal and the input operation signal are the same operation signal, and the first operation signal and the input operation signal do not stop sliding in the middle and are both signals generated by continuous sliding operation.
Correspondingly, when the first operation signal and the input operation signal are not the same operation signal, which indicates that the user has a pause in the intermediate process between generating the combined character after inputting the character and selecting the combined character, for example, the user slides continuously to generate the input operation signal and generates 3 combined characters "zhe, zha, zhu", and then the user releases the finger on the touch screen, slides to the selection area again and selects the combined character to complete the input. Although the first operation signal and the input operation signal are both signals generated by the sliding operation, the sliding process is suspended, and therefore the first operation signal and the input operation signal are not the same operation signal.
That is, the user slides to the selection area to select the combined character, and the whole sliding process can be continuous sliding or interrupted sliding. For example, the user slides to the selection area, does not stop sliding, but continues sliding to the combined character to form a complete continuous sliding to complete the input of the target character; or stopping the current sliding after the user slides to the selected area, restarting the sliding to the combined character, interrupting the middle sliding process, and finally finishing the target character input.
Preferably, when the user slides out of the selection area, the combined character group corresponding to the selection area disappears or is hidden and is not displayed, so that the interference to the vision of the user is reduced.
Of course, whether the selection area is slid or not, the combined character can be displayed at the corresponding position all the time, or the combined character in the previous selection area disappears and is not displayed after the input operation signal reaches the next intersection position.
When there are at least two combined characters in the combined character group and the selection area cannot display all the combined characters at one time, the corresponding combined characters can be displayed through sliding operation, and the corresponding combined characters are selected as target characters to be input, which belongs to the prior art and is not described herein.
As shown in fig. 2, the following process is exemplified as a specific process for inputting a target character "zha" by using the chinese pinyin input method:
step 1: according to the character height characteristics, the character sets "a, e, g, h, i, n, o, r, u, v" which may be able to follow other characters are divided into 3 character groups, the first group being "h, i, v", the second group being "a, e, n, o, r, u", and the third group being "g". As shown in fig. 2, correspondingly, the first group of characters is a first horizontal feature region and is represented by a horizontal straight line, the second group of characters is a second horizontal feature region and is represented by a horizontal straight line, and the third group of characters is a third horizontal feature region and is represented by a horizontal straight line. The three transverse straight lines are parallel to each other and do not intersect.
Step 2: the method comprises the steps of presetting five longitudinal characteristic regions, marking as a first longitudinal characteristic region, a second longitudinal characteristic region, a third longitudinal characteristic region, a fourth longitudinal characteristic region and a fifth longitudinal characteristic region respectively, representing five character length combination characters with the character length of 2-6 respectively, and correspondingly representing by five vertical straight lines.
Each vertical straight line is respectively intersected with the three transverse straight lines.
And 3, step 3: the input character "z" is obtained and used as the first letter of the pinyin for chinese.
And 4, step 4: and acquiring an input operation signal and tracking the position of the input operation signal. The user slides back and forth to the intersection of the first longitudinal feature region and the first transverse feature region and the intersection of the second longitudinal feature region and the second transverse feature region, according to the fact that the character represented by the first transverse feature region includes "h, i, v", and the character represented by the second transverse feature region includes "a, e, o, u, r, n", and the character represented by the first transverse feature region follows only the first letter "z", and the character represented by the second transverse feature region follows the character represented by the first transverse feature region and forms a combined character together with the first letter, the resulting combined character including "zhe, zha, zhu".
And 5: and (4) displaying the combined characters obtained in the step (4) in a selection area, and selecting the combined characters 'zha' from the combined characters by a user to be used as target characters needing to be input to finish input.
Example two
As shown in fig. 6, the difference from the first embodiment is that in the present embodiment, one of the lateral feature regions characterizes that the first character is upper case, and the other lateral feature region characterizes that the first character is lower case, that is, the second feature is that the first character is upper case or lower case. When the input operation signal passes through the transverse characteristic region which only represents the capitalization of the first letter, the first letter of the combined character obtained according to the first embodiment is capitalization; when the input operation signal passes through the lateral feature region representing the lower case of the first letter, the first letter of the composite character obtained according to the first embodiment is the lower case; when the input operation signal passes through the lateral feature region representing the upper case of the first letter and the lateral feature region representing the lower case of the first letter, the first letter of the composite character obtained according to the first embodiment is defaulted to be upper case or lower case or belongs to an invalid input.
Whether it is the first embodiment or the second embodiment, the longitudinal feature area characterizes a first feature of the character, for example, characterizes a character length of the compound character, the lateral feature area characterizes a second feature of the character, for example, characterizes a height of the character or characterizes a case or other of the first character, and the second feature is different from the first feature, the first feature and the second feature being different and different.
