Description

The Chinese and English hand-writing input method

Technical field the present invention relates to a kind of Method and kit for that utilizes the style of writing technology to carry out Chinese and English handwriting input.

Background technology modern society enters information-technology age, and various information products emerge in an endless stream, and total development trend is faster, stronger, littler, and promptly the processing speed of information products is fast, and is with better function, and volume is smaller and more exquisite, and operation is easier.Middle-size and small-size information terminals such as palm PC, PDA, Tablet PC, mobile phone are that future information technology is popularized the visual plant that enters family, must yield unusually brilliant results in the information handling system in future.Along with the variation of information products, information input equipment is also corresponding to change.The input equipment persons of facing such as traditional keyboard, mouse eliminate, and new input equipment is representative with handwriting pad, touch display screen, Trackpad, numeric keypad etc. then, are characterized in using the hand-writing input method that more meets people's custom.Existing hand-written Chinese character coding input method all is input Chinese-character strokes, has plenty of the whole strokes of input and discerns, and has plenty of the some strokes of input and carries out phrase identification, and what have discerns to connect stroke handwriting Chinese character individual character.They all have following shortcoming:

1. discern lowly, input speed is slow.Most Chinese character all is made up of a plurality of strokes, for improving discrimination, must write stroke by stroke, mistake can't occur in the middle of writing, even write correctly, can not correctly discern because the difference of individual writing style still has the part Chinese character.And the company's of use pen is write, and has speeded up, and discrimination has descended.

2. the program complexity is bulky.Because the general complex structure of Chinese character, stroke is various, writes recognizer and will do multiple processing and just can finish identification, and program design is also corresponding complicated, bulky.

3. Chinese, identification difficulty when English and punctuation mark mix input are switched loaded down with trivial detailsly, and complicated operation can not break away from keyboard fully.The input English character generally will be opened soft keyboard, and this had both taken the interface shape of input method, has increased the difficulty of operation simultaneously again.

Summary of the invention the purpose of this invention is to provide a kind of be simple and easy to, fast, Chinese and English input method and handwriting pad that discrimination is high.

This input method of embodiment is divided into small letter English alphabet, numeral and punctuation mark with the symbol of input, switches Chinese and English input state by function key.

Under the English input method state, write English character and identification by handwriting pad, the English character that identifies temporarily is kept in the buffer zone, computer program is retrieved the English word that starts with this character string automatically according to the English character string in the buffer zone from system English word storehouse, and (as frequency of utilization, ascending order etc.) are arranged in candidate window in certain sequence.After occurring, use required word the mode of style of writing to select this word.Program can judge whether according to the outgoing position of required word to add the space and whether initial character is converted to capitalization in the stem of word automatically.For example: write " i " writing window, computer identifies to character " i " is presented in the buffer window, and retrieves English word commonly used or phrase with " i " beginning, and for example " I, I ' d, in, I ' msorry ... " is presented at candidate window.If required word is " in ", select " in " by handwriting pad with the method for style of writing, if computer judge " in " the punctuation mark at beginning of the sentence or expression sentence end/top (.? Deng), then be automatically converted to " In ", if " in " front be an English word or other English punctuate (,/﹠amp; Deng), then add space output " in " in that " in " is preceding automatically.

Input is during English capitalization, and first selection function key " capitalization " writes English lower case writing window then, and system is automatically with the lowercase upper.

Under the input in Chinese state, be identified as English alphabet and show by writing input board input English symbol at buffer zone, computer in Chinese word library and Chinese phrase storehouse according to phonetic (comprising spelling, simplicity or imperfect phonetic) coding Chinese character retrieval or Chinese character phrase.Retrieving is that Chinese character is arranged in the candidate window with certain rule (ascending order or frequency of utilization etc.), selects input with the mode of style of writing after required Chinese character or phrase appearance.

Spelling is to import the complete Chinese phonetic alphabet of constituting word or phrase successively herein.For example: the input individual character " in ", write-once " zhong "; Import " writing " speech, write its spelling " shuxie ".Mixed assembly is the phonetic of input phrase, the word spelling that wherein has, the word simplicity that has.For example: import phrase " usually ", can write to mix and piece together " tongc " or " tchang ".Simplicity is the first letter of pinyin that input constitutes each word of phrase.For example: import phrase " we ", can write simplicity " wm ".All adopt simplicity for two-character word group commonly used and the above phrase suggestion of three words.

The phrase that does not have in the dictionary can also be remembered in dictionary by the online speech of making of completion phonetic.

Under the input in Chinese state, the punctuation mark of importing in the input Pinyin process is interpreted as the phonetic separator, and number comprehension is for to select the word or the phrase of candidate window.After selecting to import, word or phrase just can carry out the input of numeral and punctuation mark, the punctuation mark of writing is automatically converted to Chinese punctuation mark, the numeral of writing then provides various states such as arabic numeral, Chinese figure and Chinese word figure simultaneously in candidate window, select input with the mode of style of writing.

In order to adapt to individual demand, improve discrimination, input method provides the person's handwriting learning functionality, promptly before using this method input, at first carry out person's handwriting study, and the result that will learn is stored in the identification storehouse.

For realizing that handwriting pad that above-mentioned input method adopts is to be made of LCDs and its touch-screen of going up covering, writes with the mode of style of writing.Touch display screen is divided into the four-light mouth, and first is the function key window, and second portion is a buffer window, and third part is for writing window, and the 4th part is a candidate window.Wherein function key and buffer window are delegation/row, and candidate window is a multirow, and writing window is a bigger window.The relative position of four windows can change.For example: buffer window (delegation) can be positioned at the top of function key window (row) and candidate window, and three windows are positioned at the left side of writing window simultaneously.

The function key window is put into function keys such as " English/phonetic ", " uppercase/lowercase ", " simplified/traditional font ", " study ", " carriage return ", " space ", " backspace ", by style of writing mode translation function.

The English character of having discerned temporarily leaves in the buffer zone and in buffer window and shows.

Write window and write small letter English character, numeral and punctuation mark.

Candidate window can show fault-tolerant character (under learning state), English word and/or phrase (under the English input state), Chinese character and/or the phrase contents such as (under the input in Chinese states) of writing input character, and can select input by the style of writing mode.

Writing input board also can be the part of touch display screen.

Chinese and English input method provided by the invention also can with display window with write touch-screen (plate) and separate, realize by display device and apparatus for writing respectively, display device can use common computer display, LCD, televisor etc., and apparatus for writing can use common handwriting pad, Trackpad, mouse, telepilot etc.

The present invention compares with existing Chinese character entering technique and has the following advantages:

1. can use the method input Chinese and English of writing input simultaneously.

2. computer identification content is simple, only is English alphabet, numeral and punctuation mark, and the identification amount is little, and speed is fast, the accuracy rate height.

3. the amount of writing is little, meets people's thought process, has realized Chinese and English quick input, also indefatigability when service time is longer.

4. written contents is simple in structure, writes easily, can not use special-purpose writing pencil and directly uses finger writing.

5. recognizer is simple, and required hardware resource requires little, not only is suitable for various computers fields such as PC, panel computer, palm PC, network computer, also is suitable for compact applications fields such as mobile phone, TV set-top box.
