) etc., analyze relative radical part and relevant Chinese character according to the order of strokes observed in calligraphy combination of shapes of input; Parts for the minimum unit of this programme Chinese character retrieval output.
Hand-written code database feature: be the coding unit with the Hanzi component, comprise: press the sequential write of Chinese character, construct the basic stroke (a Shu Pie Dian Ya etc.) of Chinese character; Radical (Yan, Chuo, , Rolling, Rui, Mi, Fu, Bing, Ren, Xin, Woo, Yi, Http, Epileptic, Ha, Quan, Niu, Bo, Si, Si, Jin, Shi etc.); Presetting module (
Deng); Single character (wood, mouth, people, day, soil, king, the moon, horse, car, shellfish, fire, stone, order, field, worm, rice, length, nothing, hand, husband, well, in, very little, Shen, family name, crow etc.); Associated characters (product, chi, ward off, red, woods, not, the chief of a tribe, district, as, account for, chapter, folding, person,, numb, blunt, Zhu, straight etc.).By this less coding identity element of input identification, just can retrieve all required accurately words (combinde rqdical character or vocabulary) quickly.
According to the code database feature, as long as identification, detection input (less) basic stroke (element), its stroke is extracted the code area to be shown, can retrieve Regular History Frequency Chinese character or the word relevant with this stroke, words candidate regions candidate, and the relevant radical part of this stroke and associated characters and presetting module radical district candidate; Moreover choose parts, and its parts are extracted the code area show, enter the relevant words (or its element of recombinant is finished) of this component retrieval.If import its radical, presetting module, single character, associated characters (element, these element representation parts), namely extract its (element) radical or single character to the code area (or its element of recombinant is finished) again, retrieve its relevant words.
1), handwritten Chinese character district (A organizes the block) (being called for short A) is unique single Chinese character component;
2), hand-written word district (B group word district) (being called for short B) is that any coding (stroke, radical, character module) of input is the above vocabulary component of two words.
3), basic stroke input field (being called for short the C district) is to cooperate A and B or construct the words component separately.
One, " A ", " B ", " C " mutual input feature vector:
According to importing in A, B, three districts of the C district itself and three mutual inputs in district, it is replaced and encodes, increases coding, words input and vocabulary and separates the feature of demonstration:
1), replaces coding:, extract at basic stroke or the radical part that A, B, C district import
The code area shows (retrieving relevant words or relevant radical part), and judgement is that upward screen carried out in Chinese character or vocabulary, when choosing this radical part to the code area, judges whether this radical part comprises the coding of firm input, is then namely to replace, otherwise increases.
2), increase coding: enter from A, B, C district, then after radical radical part that locate in the district is chosen the code area: one, during the code element input of the A that chooses or C, be directly arrangement subsequently behind the coding that the front has been imported in the code area, according to other relevant words in the coding retrieve encoded storehouse that shows when time selecting the radical part character in radical district (if, then carry out above-mentioned " replacing coding "); Two, if when choosing B district input coding element, in B, separately arrange subsequently with the word separator before the input coding, according to other relevant vocabulary in the coding retrieve encoded storehouse that shows when time selecting the radical part character in radical district (if, then carry out above-mentioned " replacing coding ").
3), empty handwriting recognition modules A B two districts structures elemental characteristic (namely from any district, when
Cross another district, namely empty the handwriting recognition module of front region):
1., from A to B or during C, the structure element (coding) of A is extracted the code area show
With its correlated results of retrieval, and empty the hand-written module of identification in A district, the structure unit of demonstration B or C
Element, and after the code element of B or C being arranged in the element of A.
2., from B to A or during C, the structure element (coding) of B is extracted the code area shows and retrieve its correlated results, and empty the hand-written module of identification in B district, the structure element of demonstration A or C, and after the code element of A or C being arranged in the element of B.
Vocabulary input feature vector (lexicon shows automatically): a separator is represented the unit of a Chinese character of Chinese character in the vocabulary:
1) if, first of code area coding B beginning or C to B be the vocabulary input feature vector.
2), no matter which district the sintering is, as long as after the input of B district, be the vocabulary input feature vector in the input of any district again.
3) as long as, judge in the code area have one more than the coding, touch manual lexicon and then enter lexical space (or if existing lexicon then increases by a lexicon again, the word in the expression word has increased by) and be the vocabulary input feature vector.
The input feature vector of individual character: from A to B and C or from the coding additive combination of C to A; Or itself single area is finished and is individual character input feature vector (continue input again toward other zone from input back, B district and then be the vocabulary input characteristics).
The judgement characteristic of screen and radical part on the words: at the i.e. screen of choosing of " words candidate regions ", at " hand-written character or stroke retrieval radical candidate regions " and " radical part candidate regions ", judgement is that screen namely gone up in words, if radical part or associated characters are judged in the time of can retrieving other relevant Chinese character, then extract the code area, carry out the relevant of its correspondence of retrieval.
Manual lexicon feature: a separator is represented the unit of a Chinese character of Chinese character in the vocabulary, is convenient to specific and input is searched in fuzzy matching, can select to specify input (the same with automatic lexicon function) by hand or import what lexicons arbitrarily the time to participate in retrieving.
Self-defined input lexical feature: the automatic lexicon by the mutual entrance input mode of this words split or single entrance is separated or manual lexicon, and the user can realize code length and the mode to any one Chinese character in the vocabulary of input.
Specifically describe the individual character input below, with " ripe " word, " capsule " do not limit protection scope of the present invention for example at this, is clearer description the technical program only.
As shown in Figure 4, " ripe " individual character (if the traditional hand-written stroke that will import whole Chinese character), when in five traditional fonts, importing, first coding be exactly "
" (high head), the parts element that it being somebody's turn to do " ripe " front, as long as we import "
" presetting module just can retrieve other relevant Chinese character (height, capital, just, ripe, Guo, person of outstanding talent, bright, booth, in the least, cream, sorrow, inner feelings etc.); Maybe can continue the input coding element, or choose the radical candidate regions radical part (
Prosperous, enjoy, capital, height, assist, earnestly, who etc.) in " prosperous, enjoy, who " associated characters retrieve again.Retrieve relevant pictograph candidate (speech, Mang, mu, Tou, platform, Yan, tongue, stingy, account for, sound, purport);
" capsule " individual character (if the traditional hand-written stroke that will import whole Chinese character) more than 22 stroke, as long as we are the element that input should " capsule " front.
As shown in Figure 5, two groups of A, B earlier from one " one " of A district input, import one " mouth " in conjunction with input again in the B district, and at this moment the code area then shows the coding of " flatly ", can see that in the candidate block we have wanted " capsule " word of importing.
Shown in Figure 6, A, C two districts combinatorial input:
1., the A of elder generation is to C: write " one " earlier in the A district, click " Shu " button then in the C district and (at this moment empty the hand-written module in A district, etc. other element to be entered), retrieve the radical of " mouth " and choose input, at this moment the code area then shows the coding of " flatly ", the retrieve encoded storehouse, (can the relevant Chinese character of the coding of its " flatly ", thing, or, speed, whole, the official, the brother, song, puzzled, capsule, moth-eaten, bag, rely, perverse, imperial decree, force, funny, secondary, melt, the shaft of a feather) extracts demonstration, " capsule " word occurs, choose and to import, below seeing for details (the two-way input mode of AC, result for retrieval is synchronous, the left side two figure of " capsule " word exemplary plot).At the radical part candidate regions radical that obviously " flatly " is relevant (as: Shu, Bi, separate, beans).
2., the C of elder generation is to A: click " one " button in the C district, automatically extract the code area, write " mouth " (extracting the code area automatically) then earlier in the A district, at this moment the code area then shows the coding of " flatly ", the retrieve encoded storehouse, (can the relevant Chinese character of the coding of its " flatly ", thing, or, speed, whole, the official, the brother, song, puzzled, capsule, moth-eaten, bag, rely, perverse, imperial decree, force, funny, secondary, melt, the shaft of a feather) extracts demonstration, " capsule " word occurs, choose and to import, (the two-way input mode of AC below seeing for details, result for retrieval is synchronous, the right two figure of " capsule " word exemplary plot).At the radical part candidate regions radical that obviously " flatly " is relevant (as: Shu, Bi, separate, beans).
Except above-mentioned two kinds of input methods, we can also use following coded system for " capsule " word:
1), the single district of A input mode:
2), AB input mode: flatly
3), AC input mode: flatly
4), CA input mode: flatly
5), CAB input mode: a bite Mi
Specifically describing the phrase input below again, is example with " instructions " word, does not limit protection scope of the present invention at this, is clearer description the technical program only.One, we import " instructions " word, separate or manual lexicon by the automatic lexicon of the mutual entrance input mode of this words split, and according to the structural attitude of lexicon, but user's combination in any Hanzi component input vocabulary, " instructions " word can have:
1), instructions=Dian Ya Dian Pie Shu ﹠amp; Yan Ha ﹠amp; Yan Dian Pie Shu ’ Shu Ya is Pie ﹠amp one by one; Ri Yue ﹠amp; Ri Pie Ya one '
Ya Ya Shu Dian
2), instructions=Dian ' Shu ’ Ya Ya Shu Dian
3), instructions=Dian ’ Shu Ya Pie ’ Ya Ya one by one
4), instructions=Yan ’ Shu Ya ’ Ya Ya Shu Dian
5), instructions=Yan ' Ri ’ Ya
Or more kinds of any coded system typings.
As three coding inputs of following usefulness (Yan day Ya), the input vocabulary in B district " lexicon " is automatically separated automatically, is shown as: (Yan ' day ' Ya)
As shown in Figure 7, at first the cog region at B (word district) writes the 1st " Dian ", show " Dian " that has imported in the code area, demonstrating the vocabulary relevant with " Dian " at the words candidate regions (thanks, do not have, be exactly, fine, here, family, psychology, consult, why, future, speak, morals, emphatically, culture, preside over, be determined, brains, afterwards, like this etc., because touching the B district is the word district, so there is not the law of character graphics displaying of individual character, pure is lexical space), show the radical part relevant with " Dian " (the Yan Rui fire Xin Tou Http Woo Guang Ha rice Mi Bing Zhuang upright civilian door Epileptic in Yi side etc.) in the radical part district, wait to wait upon to retrieve and be correlated with.
As shown in Figure 8, at this moment both can choose the radical that " Yan " arranged in the radical part district, or directly write the 2nd stroke of " Yan " continuously in the B district, constitute the module of " Yan ", " Yan " and when being shown to the code area, namely empty code area " Dian " of input just, at this moment because " Yan " comprised " Dian " coding.Show " Yan " that has imported in the code area, and refresh the input frame interface, show in words candidate regions and candidate's radical part district to demonstrate the vocabulary relevant with " Yan " (thanks, consult, conscientious, modest, detailed, explanation, speak, detailed, setting, facility, arrange, cite sb. for meritorious service, reporter, riddle, telephone expenses, diagnosis, explain, be reasonable, ask a price, become literate, plan matters, pursue private ends, visitor, give way etc.)
Radical when " day " to input " bright ", select arbitrarily at " input of A district handwriting recognition " and " the C district clicks the button input " dual mode, when touching to any one zone in A, C district, then empty B district handwriting recognition module (for word in next word to be entered) automatically:
One, in A district handwriting recognition input (seeing Fig. 9 left side for details):
The the first sum of of " day " is " Shu ", at this moment, this has inserted a lexicon (' automatically at " Yan " and " Shu "), first Chinese character of this word of coded representation of " Yan ' Shu " is that " Yan " is relevant, second " Chinese character and " Shu " be absolute relevant (details and omissions, illustrate, see for details, give way, relinquish one's post in favor of sb. better qualified, identify, subscribe, miss eat, mistake, knowledge and insight etc.).The radical part candidate regions retrieves the relevant radical into " Shu ".When hand-written finishing " day ", automatically extract the code area, when being shown as (Yan ' day), retrieve all be the vocabulary that makes up of two radical parts of " Yan " and " day " (illustrate, say so, puzzle, mistake, topic, distinguish, proposition, metering, proof, timing, card fruit, license, subject under discussion, Nuo Man, examination question, preview, Xuchang, permitted be, instructions, permit, the person of understanding the times be).At this moment, import the stroke coding of the 3rd " book " word again in the B district
Before, insert a lexicon (' automatically), and empty hand-written module in the A district simultaneously, the code area shows is encoded to " Yan ' day '
", " instructions " this vocabulary occurs, can choose input.
Two, click button input (seeing Fig. 9 the right for details) in the C district:
The the first sum of of " day " is " Shu ", chooses the button of " Shu " in the C district, and the coding of " Shu " is extracted the code area.At " radical part candidate regions " radical part relevant with " Shu " appearred the candidate, radical district " day " radical in elected, the coding that " Yan ' day " arranged in the radical part district, choose namely empty code area input just " Shu, at this moment because " day " be to have comprised that " Shu " encodes.Show " Yan ' day " imported in the code area, words candidate regions and radical part show result displayed and on " Yan ' day " of hand-written recognition coding the same.At this moment, click the stroke coding “ Ya of the 3rd " book " word of input again in the C district ", institute's result for retrieval is the same with hand-written result.

1. a handwritten Chinese character input method is characterized in that, imports with coding form, and retrieves according to coding, and described coding refers to the hand-written character of input is transformed to Hanzi component as the coding of code element; Described handwritten Chinese character input method has also adopted and has clicked and hand-written synchronous input, and input mode is divided into the input of phrase coding and encode Chinese characters for computer input, and its step is as follows:
S1, the input field is divided into two districts of A, B, handwritten Chinese character input Hanzi component will be presented at the code area behind the Hanzi component recognition coding, execution in step S2;
S2, the described Hanzi component of judgement are the input of phrase coding or encode Chinese characters for computer input, if then execution in step S3 is imported in encode Chinese characters for computer, if the phrase coding is imported then execution in step S6;
S3, input coding is retrieved, the progressive district of relocatable module can show and comprises word, hand-written character or the Hanzi component of input coding, execution in step S4;
S4, judge the Chinese character whether the needs input is arranged shown in the progressive district of described relocatable module, if have, then the location is shielded on choosing namely and is emptied the code area, if do not have, then see whether the Hanzi component that needs the input Chinese character is arranged in the progressive district of described relocatable module, then execution in step S5 is arranged, then do not continue input in the arbitrary district in the A district except first stroke of a Chinese character input field and B district if having, directly arrange subsequently behind the coding of having imported that new input will show in the code area, execution in step S3 then, if continue input in first stroke of a Chinese character input field, the coding of input before the code area can be upgraded, execution in step S3;
S5, judgement choose Hanzi component whether to comprise the Hanzi component of input before, comprise the coding of input before then replacing it and are presented at the code area, and execution in step S3 does not comprise then directly arrangement subsequently behind the input coding of code area demonstration, execution in step S3;
S6, input coding is retrieved, the progressive district of described relocatable module can show and comprises word or the Hanzi component of input coding, execution in step S7;
S7, judge shown in the progressive district of described relocatable module whether the word that needs input arranged, if have, then the location is shielded on choosing namely and is emptied the code area, if do not have, then see whether the Hanzi component that needs input is arranged in the progressive district of described relocatable module, then execution in step S8 is arranged, if there is not then to continue in the A district except hand-written word district input, after will adding lexicon at the coding of having imported that the code area shows, new input directly arranges subsequently, execution in step S6, if continue input in hand-written word district, the phrase attribute coding of input before the code area can be upgraded, execution in step S6;
S8, judgement choose Hanzi component whether to comprise the phrase attribute coding of input before, the phrase attribute coding who comprises input before then replacing it is presented at the code area, execution in step S6 does not comprise then and directly arrange execution in step S6 subsequently behind the phrase attribute coding who has imported of code area demonstration.
2. handwritten Chinese character input method according to claim 1, it is characterized in that, described Hanzi component refers to form the element of Chinese character, comprise Chinese-character stroke, the individual character that can form other Chinese character, radical and according to the Chinese-character writing order, write the element that several continuous radicals become with stroke combination; Described recognition coding is that the character of handwritten Chinese character input or the Hanzi component in Hanzi component and the code database are mated, and the Hanzi component with coupling is presented at the code area then.
3. handwritten Chinese character input method according to claim 1 is characterized in that, judgement is that the input of phrase coding or the method for encode Chinese characters for computer input comprise:
Method a, the input field is divided into two districts of A, B, from the first stroke of a Chinese character of A district, then is considered as the encode Chinese characters for computer input in the input of A district always, when jumping to the continuation input of B district, to still be considered as the encode Chinese characters for computer input, but after the input of B district is finished, replace input if also will go to the A district, all will be considered as the input of phrase coding; From the first stroke of a Chinese character of B district, the back is always in B district input, or goes to A district and realize that B district, A district alternately imports and all be considered as phrase and encode and import;
What method b, manual selection were imported is encode Chinese characters for computer input or the input of phrase coding.
