Abstract
The invention relates to a touch screen key-writing input method, which comprises the following steps of: A, writing keys of characters on a touch screen, according to the written keys, identifying the keys as being equal to keypress response of a substantial keyboard by a system, and directly displaying corresponding key characters or character groups on the touch screen; and B, listing candidate characters or character groups meeting the key requirements for selection. In the various prior input method environments, a process equal to the process of continuous or single encoding (key-writing) input for appointed letter symbols through the encoding rules of the input method on the substantial keyboard is implemented, complete individual characters or complete word groups can be output only in once hand input acknowledgement, and the target content can be output without performing the input acknowledgement many times. In the method, two input environment modes of continuous key-writing input or single key-writing input are set so as to (1) improve input speed and work efficiency and (2) improve accuracy and meet the requirements of users who are slow in operation.
Description
Technical field
The present invention relates to a kind of touch-screen and write key input method.
Background technology
Existing many interactive devices or communication apparatus all are provided with touch-screen, and purpose is direct input message on touch-screen for the convenience of the users, and the handwritten Chinese character input equipment of existing touch-screen class or the input method of small size communication apparatus are generally:
1, directly write out the word that will input at touch-screen with the form of stroke, then terminal device is identified at the character of finding out correspondence according to character library.
2, the soft keyboard that utilizes touch-screen to provide is selected input, and in this kind input method, system may be equipped with the concrete option of phonetic or stroke, and the user selects corresponding soft keyboard keys to input at touch-screen.
But above-mentioned two kinds of input methods commonly used can run into some problems in the use of reality, and during such as the use first method, handwriting input Chinese character or letter all are to write Chinese character or letter by stroke at screen individually.Although be the writing style that has satisfied people, cost of development is high, hardware resource huge take and the hardware identification rate low.If the Chinese character more complicated of input is when maybe will input the multiword word, the recognition effect of terminal device is often bad or not can realize, because each operator's input habit is different, can cause unavoidably and write font and standard letter is variant, the situation that Palingraphia may occur repeatedly, very trouble; And the second input method when the touch-screen size of terminal device hour, such as PDA or mobile phone.The corresponding also size of the soft keyboard that occurs on the touch-screen is less, just very little specific to each button on the soft keyboard, a lot of equipment have been equipped with felt pen in order to overcome this problem, but felt pen uses and carries still very inconveniently, and also the user has brought trouble.
Be 201010283958.8 such as application number, the applying date is on September 17th, 2010, patent name is the patent of invention of " spelling input method that is used for touch-screen ", its content is: the spelling input method that is used for touch-screen, formed by virtual consonant keyboard and vowel keyboard and Chinese character to be selected district, according to the principle of phonetic transcriptions of Chinese characters by " initial consonant+rhymes " formation, click first or touch the consonant key on the consonant keyboard, system dynamically demonstrates the vowel keyboard that is used with current initial consonant, click again or touch the final key on the vowel keyboard, only need 2 clicks or touch the input of namely finishing a phonetic transcriptions of Chinese characters.Can see that from above-mentioned patent accompanying drawing its dummy keyboard requisite space is still very large, if carry out the input of this literal at the small size communication apparatus, very possible because overdue and cause input error.
Based on above-mentioned factor, the subject matter of existing inputting method of touch screen has:
1, the recognition speed of current touch screen hand-writing imputting Chinese characters is slow and accuracy rate is not high.There is repeatedly slow hand-written situation about repeatedly confirming for some Chinese character, directly caused handwriting input speed slack-off.Equipment volume is little, little input speed and the accuracy rate of greatly having affected of button area.
2, present, the handwritten Kanji recognition technology only limits to the identification of individual Chinese character, can't finish the identification input to word.Do not have the continuous input of word, be difficult to improve the input speed of handwriting input.
3, do not reduce user's hand-written labour intensity, the direct handwriting recognition technology of Chinese character is larger to taking of device hardware resource simultaneously, has increased the cost of Chinese character information device hardware.
Summary of the invention:
For the problems referred to above that existing touch-screen input method exists, now to invent a kind of touch-screen and write key input method, its particular content is:
A kind of touch-screen is write key input method, it is characterized in that may further comprise the steps:
The key mapping character of A written character on touch-screen, according to the key mapping character that writes out, system identification is the key response that is equal to keyboard in kind, and directly shows corresponding key mapping character or character group on screen.
B lists and meets candidate characters that key mapping requires or character group for you to choose.
In existing various input method environment, realization is equal on the keyboard in kind to be inputted specifying letter symbol to finish continuous or single encoded (writing key) with this input method coding rule, in a handwriting input is confirmed, can realize exporting complete individual character or complete word.And needn't be through after the input validation repeatedly, ability export target content.Arrange and write continuously key input or single two kinds of input environment patterns writing the key input, purpose is that (1) is in order to improve input speed and work efficiency; (2) in order to improve accuracy and to satisfy the slow user's needs of operation.
When wanting the Chinese display character, on touch-screen, according to the input method coding rule, in input validation once, write the letters case coding of Chinese word or word and finish input operation, and in conjunction with various existing input methods rules (such as phonetic etc.), realize the purpose of export target content.
Want demonstration and the input of Chinese display Chinese character, can be on touch-screen continuously or write out individually the coding (key mapping) of multiword word, can display symbol on the screen being merged the multiword word of writing requirement inputs for you to choose, and in conjunction with various existing input methods rules (such as phonetic etc.), realize the purpose of export target content.
After completing steps A, be provided with the affirmation time of input coding, exceed above-mentioned acknowledging time system and think that then the first word of current coding section or word are identified and finish input and show corresponding individual character or word (namely exempting from the affirmation operation of lead-in word).
The affirmation time of input coding is 1.2 to 2 seconds.
When the efficient coding that writes is identified, when candidate characters or literal occurring one by one on the display screen, the user touches specific character or the input of prescribed coding character or literal can be finished in literal, and needn't all write complete coding.
Shown Chinese character and the word for input of described step B can be the encode method for entering Chinese characters that comprises on the current Chinese characters of all of Chinese-language input method keyboards in kind.
On various hand-written touch screens, directly " writing key " finished and is equal to the input that keyboard mode in kind is finished English text, inputs a plurality of key mapping characters and identifies writing continuously key in an input operation.
On various hand-written touch screens, write key and finish the input of any languages literal (such as Korean, Japanese, the Arabic etc.) letter symbol take the Latin alphabet as code symbols that is equal to keyboard mode in kind, a plurality of English characters of input are identified continuously in once inputting.
Beneficial effect of the present invention:
1, avoided directly writing Chinese or the trouble of Chinese character other outside at touch-screen, be reduced to the mode of inputting corresponding input method coding and identify, improved input speed and accuracy rate on little touch-screen.
When 2, inputting individual character, allow once input whole codings in the input, and needn't input again next coding after a coding input affirmation, saved input time; When input word or foreign language word, can once in the input coding of whole word or foreign language word all confirmed after the input again, then the disposable target character that obtains.
Description of drawings
Fig. 1 is the flow process diagram of the present invention from input coding to the display-object character.
Fig. 2-Fig. 5 writes the key input method example operation for Chinese/English touch-screen, the effect synoptic diagram of Chinese as an example of Chinese-language input method example.
Embodiment
The idiographic flow that whole character shows is: begin to write key, write out the corresponding key mapping character of actual physics keyboard at the screen left-hand seat; Touch-screen is accepted the information of hand-written key mapping; The CPU fuzzy diagnosis is the computer-internal character, and take a kind of existing input recognizer as the basis, lists the candidate characters that all meet identification; The user can arrange the length of acknowledging time, then automatically selects input character with numerical key 1 correspondence when surpassing acknowledging time, as confirming in acknowledging time, then take the character confirmed as input character; In conjunction with existing input method, the character with inputting in the past adds and the coding of this character match, draws one group of target character; Target character is presented on the touch-screen, and Digital ID in addition; The user did not confirm within the affirmation time period of setting, then take primary character group as object output, when the user touches affirmation or touch the click respective symbols, then export user-selected character, if all there is not correct character, then the user is from new hand-written new character.
The Chinese touch-screen is write key input method example operation (take Chinese-language input method as example).
(1) input of individual character: as shown in Figure 2, the input coding of writing key input " Ji " of individual character: Ji=north (b)+field (t)+common (g)=btg.
Fig. 2 explanation: illustration shows in the pattern that the odd one key mapping writes, and Chinese character is write key and demonstration situation under " Chinese-language input method " environment individually.First coding key mapping character " b " that 1 expression is write out individual character " Ji " with finger or felt pen in touch screen is selected input field (similar character candidate regions) in when definite, is equal to the system responses that keyboard in kind is pressed the b key mapping; And confirm that immediately this key coding is effective literal code; In the indication range of display screen license (for example a screen display is shown 10 Chinese characters, 20 half-angle characters) demonstrate the Chinese character that satisfies this coding (or under the non-Chinese character state other languages characters).When if 2 expressions continue to write second key coding " t " according to coding rule, system makes and is equal to keyboard in kind and presses continuously the Chinese character (or under the non-Chinese character state other languages characters) that the key mapping of b, two key mappings of t shows response and satisfies this coding section.3 expressions are behind the three basic key coding b that finishes " Ji ", t, g, and " Ji " appeared in the literal candidate region of screen, if write corresponding numeral identification key mapping " 3 " again, can finish " Ji " and really give up into (so showing such as 4,5).No matter at which write in the step display of key input, input validation and the character in the screen display area of all finishing this character/literal on the relevant position of tangible candidate characters/literal candidate candidate regions show.
(2) two-character word language write the key input: as shown in Figure 3, the input of " information ".Coding: information=letter (Ren+speech)+breath (from+heart)=r+y+z+x=ryzx.
Fig. 3 explanation: illustration shows in the pattern that the odd one key mapping writes, and two word Chinese-character words are write key and demonstration situation under " Chinese-language input method " environment.1 to 3 expression write key and demonstration situation with 1 to 2 situation of illustration two identical but many hand-written key mapping of a step be identification.Situation when the character that 2 expressions write is identified as " r " key mapping.With it corresponding Gong candidate's Chinese character individual character or word when 3 expressions continue to write second effective encode Chinese characters for computer of key input.Situation when 4 expressions continue to write the 3rd effective key mapping character.At this moment, key mapping identification may appear again, if when being identified as " ry2 ", then be exactly when writing " ry " (previous step) " he " in the Chinese character candidate regions be selected and finish input.5 expressions write the demonstration situation of 4 key mappings continuously.When writing the basic key coding of key input " information ", key mapping and corresponding Chinese character two-character word language shown in candidate regions with it.When wanting (1) to select to be positioned at the first word of this coding section (information), the user can not do any operation of writing key or button, waits for peacefully 1.2---and after 2.0 seconds, the word that ranks the first is automatically confirmed and is transfused to; (2) directly touch " affirmation " key and finish the input of the word that ranks the first; (3) write out the word order indicated in the candidate regions number and finish the input of non-the first word, for example: write key and go out key mapping: ryzx3 can finish the input of " mailbox ".
(3) write continuously key input: as shown in Figure 4, " China " (zsfv) write continuously the key input.
Fig. 4 explanation: illustration shows in writing continuously key pattern environment, writes continuously the situation that key is inputted Chinese individual character or word.1 is illustrated in and writes continuously under the key pattern, and (the Chinese coding: behind first key mapping character " z " zsfv), system correctly identifies, and the demonstration situation in input candidate regions and literal show candidate district to write " China ".2 expressions write key mapping character " s " again less than in 1.2 seconds the time interval, the corresponding demonstration situation of system in input candidate display district and literal output candidate regions.3-5 write key and input, output display with 2 in like manner.If 5 expressions finished " China " all basic codings write key input after, can (1) wait for peacefully 1.2-2.0 seconds after, system automatically finishes the affirmation of the first word or word and is output and is shown to the text display district; (2) continue to write figure case, finish choosing and can be output and being presented at text area of corresponding candidate target character.(3) literal of touch numeral can be output and be presented at text area.In any step of 1-4, the literal that all can touch numeral is output and is presented in the text area.Can not show later on when writing key operation if the screen that exceeds too much write in the character the when user writes key, system dwindles the hand-written key mapping character that the user has write automatically in the original shape ratio, so that remaining key mapping character is continued to write.
2. English write the key input: as shown in Figure 5, English word " teacher " write the key input.
Fig. 5 explanation: 1 is illustrated under the English input environment, when writing key input key-position letter " t ", in input field (similar character candidate regions), when the key mapping character that writes is selected when determining, the key response that is equal to keyboard in kind is made by system, shows with English alphabet " t " is the most adjacent in the dictionary ordering to be shown complete word (4 of this examples).The most contiguous complete word (3 of this examples) that is shown in the dictionary ordering is write behind two key-position letters of key input " te " in 2 expressions continuously.Key input " tea " 3 key-position letters are write in 3 expressions continuously.Because the English word with these three key-position letters form does not change in the sequencing display scope, so the word of candidate regions shows also without changing.When key input " teac " is write in 4 expressions continuously, in the candidate regions indication range, only have three English words to match, and be revealed.If (1) do not do any operation of writing key or button, wait for peacefully 1.2-2.0 seconds after, the word that ranks the first (teach) is automatically confirmed and is transfused to; (2) directly touch " affirmation " key and finish the input of the word (teach) that ranks the first; (3) continue to write key input key mapping " 2 " and namely write continuously key input " teac2 " (shown in 5), " teacher " namely by complete input, and needn't write " teacher " all effective key mappings (shown in 6).
