Description

Chinese-character shape-first phonetic letter input method with numeral keypad

The present invention relates to a kind of computer input method for Chinese character.

Existing input method of Chinese character mainly is applicable to the Chinese character input of the QWERTY keyboard that contains 26 letter keys.The keypad that is less than 26 keys, particularly the Chinese character input that comprises the keypad of 10 numeric keys as telephone set, mobile phone etc. still lack not only easy but also high-efficiency method.Normally used phonetic method has the many shortcomings of repeated code and requires the user to pronounce accurately, it is special when it is used for the input of numerical key, go up 26 phonetic alphabet that distribute owing to be no more than 10 keys (being set to 8 numerical keys usually), need double hit to select required letter during input, code length is obviously extended.And there is the difficult shortcoming of grasping in other digit key input method.As application number is 98123365.1 the disclosed method of application for a patent for invention, select some basic stroke of Chinese character and parts to be divided into ten groups of corresponding 10 numerical keys and carry out the spell shape input, this method must hypermnesia basic stroke and parts and with the corresponding relation of numerical key.

The purpose of this invention is to provide a kind of easy to learn and digital keyboard Chinese character input method efficiently.

The present invention is achieved through the following technical solutions goal of the invention:

With 26 English alphabets is that Chinese phonetic alphabet is distributed on the numerical key, and distribution mode can adopt normally used mode on the telephone set.Common have 10 key formulas and 8 key formulas, being distributed as of 10 key formulas: 1abc, 2def, 3ghi, 4jk, 5lm, 6nop, 7qr, 8stu, 9vwx, 0yz; Being distributed as of 8 key formulas: 2abc, 3def, 4ghi, 5jkl, 6mno, 7pgrs, 8tuv, 9wxyz.Also can be defined as 9 key formulas separately, or to 8 key formulas and the redistribution of 10 key formulas.The key position of 10 numerical keys is arranged and can be adopted existing various keyboards arrangement mode separately, also can arrange separately.

The method of Chinese character coding is: first yard is the corresponding numeral of first letter of this character pronunciation; Second yard, trigram are respectively by this wordbook and write corresponding numeral of first letter that order splits out the pronunciation of parts; The numerical coding of the first stroke correspondence of this word of usefulness that less than is four yards.Stroke encoding is identical with five-stroke character input method, and promptly 1 horizontal stroke (carrying), 2 perpendicular (perpendicular colluding), 3 left-falling strokes, 4 points (right-falling stroke), 5 are rolled over five kinds.To the single character that be difficult for to split, second yard, trigram, the 4th yard are respectively that this wordbook is write the numeral that order splits out first three stroke correspondence.To uncommon, the not readable parts that split out with the lower numerical coding of a frequency of utilization.The disassembled coding of speech rule is got the preceding trigram of first word and first yard of second word for two-character word, and preceding two yards and the every word of back two words first yard of first word got in three words, and first yard of the every word of first three word with last word first yard got in four words and the above speech of four words.

This input method also can reduce the input difficulty and improve input speed by Chinese character is sorted, make the program of this input method simple simultaneously, and it is little to take up room, and travelling speed is fast.Can further reduce input difficulty, raising speed in conjunction with the display reminding function.

This input method has been compared following advantage with the phonetic method: at first greatly reduce the repetition rate of coding, Chinese characters in common use have more than 6,000, and phonetic only has hundreds of combinations, and a large amount of repeated codes are inevitably, and this method encode Chinese characters for computer combination has 8 in theory ⁴(8 key formula) or 9 ⁴(9 key formula) or 10 ⁴(10 key formula) plants, and it is conspicuous reducing the repetition rate of coding; Secondly, obviously reduce code length, because phonetic uses on numerical key, need the same key of double hit to select the required letter of this key, code length is multiplied, and the different letters on the same key of this method are considered as same numerical key, all hit primary key to get final product; Once more, this method is only used first letter of Chinese-character pronunciation, need not the user and pronounces accurately.Compare this method with other digital-key Chinese character input methods and have characteristics easy to learn, Chinese character is mainly pressed writing style and is split, and need not special memory.In conjunction with the Chinese character sort of program, the setting of screen display prompting and tolerant code makes this method simple and effective more.

Accompanying drawing 1 is the program circuit synoptic diagram of this input method.

Accompanying drawing 2 is the exemplary plot of this input method screen prompt method.

Below be that example specifies the technical program with 10 key formulas, this programme all is suitable for 8 key formulas and 9 key formulas, only the distribution on numerical key is adjusted accordingly and gets final product to letter.

One, the rule of divining by means of characters

With 26 English alphabets, promptly Chinese phonetic alphabet is distributed on 10 numerical keys, and Chinese character is carried out disassembled coding according to preceding method:

1. as far as possible according to the structure custom of Chinese character, Chinese character is splitted into two parts

First letter of getting the phonetic of this Chinese character is first yard;

Phonetic first letter of first title that splits out is second yard;

Phonetic first letter of second title that splits out is a trigram;

The letter of the first stroke correspondence of this Chinese character is the 4th yard.

For example: example → routine people is listed as left-falling stroke → LRLI → 5753_3

As → as woman mouthful folding → RNKM → 7645_1

(last be under the situation of repeated code by " the word selection sign indicating number " of the interim appointment of program, generally sort automatically according to hanzi frequency count)

2. can split into two portions and not split into three portions, can split into three portions and not split into four portions

Greater than two ones Chinese character, preceding trigram code taking rule is the same;

Phonetic first letter of the 3rd title that splits out is the 4th yard.

For example: example → routine people is listed as left-falling stroke → LRLI → 5753_3

(generally not splitting into " the bad cutter of routine people ")

The careless precious Lu → YCBL of battalion → battalion → 0115_2

(generally not splitting into " precious mouthful mouthful of battalion's grass ")

Energy → energy Si month an ancient type of spoon → NSYB → 6801_2

3. the word to being difficult to take apart is got first three and is drawn (single word of drawing repeats to get first and draws)

First letter of getting the phonetic of this Chinese character is first yard;

Getting the corresponding letter of this forms of first strokes of Chinese characters picture is second yard;

The letter of getting this Chinese character second stroke correspondence is a trigram;

The letter of getting this Chinese character the 3rd stroke correspondence is the 4th yard.

For example: hand → hand is cast aside horizontal → SIAA → 8311_1

One → one horizontal horizontal stroke → YAAA → 0111_2

If go into → go into to cast aside press down left-fallings stroke → RIJI → word that is difficult to take apart of 7343_14., remove one after, what be left is that first letter that common parts are got the phonetic of this Chinese character is first yard; Getting the corresponding letter of this forms of first strokes of Chinese characters picture is second yard; The letter of getting the remaining part correspondence of this Chinese character is a trigram; Getting the corresponding letter of this forms of first strokes of Chinese characters picture is the 4th yard.(all the other situations are analogized) for example: the horizontal big horizontal stroke → TADA in sky → sky → 8121_2

I → I cast aside and look for left-falling stroke → WIZI → 9303_25. stroke to be divided into five classes, respectively corresponding different letter/number

The corresponding numeral of the corresponding letter of stroke title

Horizontal (carrying) A 1

Perpendicular (lifting-hook) F 2

Cast aside I 3

Press down (point) J 4

Folding M 56. uncommon, not readable sound/shape can be torn open and is " monster ", represents also can to use current one one of " * " wildcard with alphabetical O (promptly digital 6); (relevant " monster " portion, with reference to the parts table of induction of back) for example: difficulty → difficulty is people monster → NYRO → 6076_1 again

Difficulty → difficulty is the people again? → NYR* → 607*_2

Black → perpendicular → HODF → 3622_1 of black strange point

Black → black? point is perpendicular → many yards of H*DF → 3*22_27. one words: and to the different polyphone (or portion) of first letter of phonetic, be with multiple coding to being easy to generate the different Chinese character that splits, also available multiple coding; For example: OK → the horizontal fourth → XRAD of pedestrian → 9712_1

OK → the horizontal fourth → HRAD of pedestrian → 3712_1 (polyphone)

Disastrously → miserable heart ginseng point → CXCJ → 1914_2

Disastrously → miserable heart ginseng point → CXSJ → 1984_2 (multitone portion)

Chapter → Zhang Yinshi point → ZYSJ → 0084_1

Chapter → chapter founds breakfast → ZLZJ → 0504_2 (the different fractionation)

Different → different the sixth of the twelve Earthly Branches grass folding → YSCM → 0815_1

Different → dissident's grass folding → YJCM → 0415_1 (the different fractionation)

Different → different strange grass folding → YOCM → 0615_1 (the different fractionation) the 8. phrase of two words of input rule of word gets the preceding trigram of first Chinese character and first yard of second Chinese character, synthetic four yards; Preceding two yards and the back first yard of two Chinese characters of first Chinese character, synthetic four yards got in triliteral phrase; The phrases that three words are above are got first yard and first yard of last Chinese character of first three Chinese character, synthetic four yards; Two, this input method stroke partly commonly used, parts, one-tenth word table of induction

Illustrate that 1. black matrixes represent not too commonly, or specifically defined parts are arranged; In order to accelerate input speed, the suggestion memory;

2. the common different fractionation that splits parts:

Gui (G): soil soil (TT) Lou (L): rice woman (MN) extends (G): in case (AD)

Assist then (Y/O): Ji strange (XO) of (X): Wen Koukou (WKK)

The parts of common polyphone: long (C/Z), ginseng (C/S), once (C/Z)

3. the fractionation rule of common parts:

Portion _ left side: a upright mouthful of butterfly _ right side: generation wood a court _ left side: ten morning pair _ left side: a bite field

Do not have _ right side: youngster is the warp _ right side again: strange worker bath _ right side: product wood is drunk _ right side: day is strange

Volume _ head: eight husbands are multiple _ on: a day for human beings drum _ left side: ten beans/scholar's mouth monster

4. because fault-tolerant, symbol under unified control and prompting are cleverly arranged, so, also can easily fail Chinese character even do not remember parts!

Three, the method that Chinese character is sorted

1. the basic frequency of utilization with Chinese character is a preface, by the rule encode Chinese characters for computer of divining by means of characters-give;

2. to utmost point Chinese characters in common use, surname word, address, appellation ... frequency values improves;

3. to extremely difficultly tearing Chinese character open, causing the different Chinese character that splits easily, frequency values suitably improves;

4. inferior difficulty is torn open Chinese character, may cause the different Chinese character that splits that frequency values improves slightly;

To above-mentioned Chinese character according to new frequency, reunify ordering, in real-life program, use the sequencing table of this input method.

Four, the screen prompt mode of this input method (default Chinese character chooses suggestion to accord with " # ")

This input method is carried out indicative demonstration on the display screen that keyboard connected in Chinese character input process:

In satisfying the Chinese character group of present encoding condition, first high frequency Chinese character is caught up with " # ", and next sign indicating number that the individual high frequency Chinese character of second to N (N is generally 6 to 10) is got each own coding is keying;

Last sign indicating number if be totally lost, first high frequency Chinese character still can be caught up with " # ", and second to N high frequency Chinese character gets 2,3,4,5 successively ... N is a keying.If one page does not show, can turn over screen and show.

Five, punctuation mark and numeral and alphabetical input

Double hit four times 8 (also can be set to other modes) under the functional status of this input method, the screen display punctuation mark can be selected input.

Carry out function by function key and switch, can realize the input of numeral and letter.

Further illustrated below in conjunction with the program and the prompting mode of accompanying drawing this input method.

Fig. 1 has shown the roughly flow process of this input method procedure, and this flow process shows that owing in advance Chinese character is sorted, program only relates to simple condition query, does not relate to sort algorithm.It is easy that program is realized, if its core algorithm is used the C language representation, only needs about 300 row; Travelling speed is fast; Occupy little space, account for static memory (or being called Flash) with the calculating of 6700 words and be less than 40K.

Fig. 2 has exemplarily shown this input method screen prompt mode, and three diagrams are common mobile phone screen specifications, and square frame is a screen form, is the prompting show state in the square frame, and frame right side numeral is the screen scale.

This input method also can be used for the Qwerty keyboard input, and this moment, the coding of Chinese character was not directly represented with corresponding English alphabet with numeral.By the corresponding modify of program, can further reduce the code length and the repetition rate of coding when on QWERTY keyboard, importing.
