CN1074557C - Direct-view code for Chinese character input method and keyboard - Google Patents

Abstract

The present invention provides a Chinese character input method for a computer. The method uses visual shape with the form of geometric description of character shape codes and codes the Chinese characters by Latin letters (from A to Z). The method directly determines key positions by the same or the similar relationship of the shape of the basic components of the Chinese characters and the shape of key letters (capitalization), and does not need any transformation of shape and sound or any process of dividing divisions for positioning. The method uses a plurality of fixed character shape codes for describing the position relation among the components of the Chinese character, which makes the effect of one-dimension coding equivalent to that of two-dimension coding, and meanwhile, the method avoids the thinking of two-dimension cross judgment. The Chinese character input method is obviously better than the existing input technology at the aspect of easy learning. The method has the characters of simplicity and easy learning, low rate of coincident codes, high input speed, etc., and has good application prospects.

Description

Direct-view code for Chinese character input method and keyboard

The present invention relates to a kind of method of Chinese character coding and keyboard thereof, particularly a kind of direct-view code for Chinese character input method and keyboard thereof.

Along with the arrival of information age, computer technology is popularized day by day and is promoted in China, and the Chinese information processing modernization process is constantly accelerated, and is more and more higher to the Technology of Chinese Information Processing requirement.

In decades, in order to solve the problem of Chinese character input computing machine difficulty, the descendants of the Yellow have carried out persevering endeavors at home and abroad, create nearly thousand kinds of Chinese character input methods, in the process that realizes the four modernizations, have composed the chapter that is with historically new significance.

Acquired achievement makes us filled with exultation.Simultaneously, we also see, the difficult problem of Chinese character input does not obtain solution fundamentally as yet: easily the input method input speed of learning is slow, and high input speed not eager to learn again forms " bottleneck " problem of Chinese character input.The phonetic sign indicating number is simple, perhaps need not heavily learn (as " spelling "), perhaps learning difficulty little (as " Two bors d's oeuveres "), but the repetition rate of coding is too high; The existing phonetic shape code repetition rate of coding low (as " king's sign indicating number ", " Zheng's sign indicating number ") can realize " touch system ", but it is numerous and diverse to split rule, and memory capacitance is big, finds it difficult to learn easily to forget.

" intuitive-code Chinese character input method " that today, we provided, be that several thousand Chinese characters are being carried out on the basis of omnibearing analysis, contrast, conclusion, arrangement from shape, sound, adopted several angles, to the typical method of Chinese character coding analysis and research of kind more than ten, learn from other's strong points to offset one's weaknesses the novel Chinese-character input scheme of designing.The core of scheme is the method Description of Chinese Character Structure with pictograph directly perceived.

The existing method of Chinese character coding based on shape perhaps adopts shape sound shape to change true fixed key position method, perhaps adopts partition to locate true fixed key position method.Shape sound shape is changed true fixed key position method, as " popular phonetic-stroke code ", the member (shape) of Chinese character is changed audio earlier, determines the enter key position according to sound again.For example, " building " word is made up of " wood ", " rice ", " woman " three members.Their phonetic transcriptions of Chinese characters is respectively MU, MI, NU.The initial consonant MMN that gets each member in view of the above successively makes the coding of " building " word.The shortcoming of this method is: one, a lot of members independently do not become word, so accordatura artificially increases memory capacitance; Two, during typing, brain constantly carries out the conversion of shape sound shape to be judged, causes fatigue easily.

The partition localization method as " five fonts ", with the member of Chinese character, is determined to distinguish under this member according to the first stroke of a Chinese character, the position in determining to distinguish according to further feature again, and the position is in conjunction with judging the corresponding keys position.This method is regular strong, through long-time study and training, and can be on top of.But its disadvantage is that learning difficulty is big.Show that mainly the initial memory capacitance of crossing the threshold is big, and the position judges and causes brain fag easily, so normal operating range does not generally exceed professional typing personnel.And general personnel hang back often." Zheng's sign indicating number " also belongs to partition location font code, uses major-minor dicode system simultaneously, and system is tight.But same difficult note is easily forgotten, and judges that difficulty is also greater than " the Five-stroke Method ".

The objective of the invention is to provide a kind of also more much easier than learning phonetic, as long as can just can import Chinese character by writing of Chinese characters, shoot straight, direct-view code for Chinese character input method that memory capacitance is little and keyboard, make Chinese character be entered as into everybody can popular general knowledge, thereby solve " bottleneck " problem of Chinese character input substantially.

The object of the present invention is achieved like this: this direct-view code for Chinese character input method is to adopt shape holder directly perceived to be aided with the form of font sign indicating number geometric description, and (A-Z) encodes to Chinese character with the Latin alphabet, realizes with computer keyboard input Chinese character and phrase.Direct-view code for Chinese character input method is according to the shape and the directly true fixed key position of the same or analogous relation of key letter shape of Chinese character basic building block, without any need for conversion of shape sound shape or partition location process.The code fetch order is removed the few cases, meets Chinese character tradition order of writing strokes.As: day----GP, fourth--J, are cried--OW, skill--HZ for B, the fourth of the twelve Earthly Branches.Sign indicating number directly perceived has been followed the principle of describing Chinese character member with similar shape or nearly shape letter key from start to finish, and the integrality that has as far as possible kept HF components and some difficulties to tear member open has simultaneously been avoided the meticulous fractionation to the Chinese character independent sector.Especially to tradition Chinese character radicals by which characters are arranged in traditional Chinese dictionaries commonly used, represent with solid size or dicode without exception.

Sign indicating number directly perceived carries out rough description with four fixing graphemic codes to the relation of the position between Chinese character member, and it is two-dimensional encoded that the actual effect of one-dimensional coding is equivalent to, and has guaranteed that simultaneously the probability that graphemic code and similar shape spare code weight close is minimum.

The method of Chinese character coding specifies as follows:

Sign indicating number code length directly perceived is 4.

㈠, basic component

It is basic component that sign indicating number directly perceived selects following 26 group word members.Their common feature is, and is strong with the pictograph of corresponding key letter: little day Contraband order Ji Lv Shu fourth Zhuang _ pawl A B C D E F G H I J K L M Jiong mouth Jie is chi _ ㄩ people's one メ bifurcation second N O P Q R S T U V W X Y Z example again:

One----NNU

(3), font sign indicating number:

Sign indicating number directly perceived is defined as four kinds with position relation between Chinese character member: upper and lower relation, about relation, surround relation and cross reference.Can separate between the member, can also connect.The relation of encirclement can be full encirclement, can also be semi-surrounding.Cross reference can be direct intersection, can also be nested intersection.About sign indicating number directly perceived is represented with I, W, Y respectively, about and encirclement or cross reference.After the font sign indicating number was added in two words and three words, full part word did not add the font sign indicating number.

In addition, sign indicating number directly perceived is ■ 〓 type-word in three words of left right model (two up and down on one on the left side, the right), as " press ", " walk back and forth ", be defined as three words of standard, and represent with font sign indicating number H.Example: piece: several wood of separation relation----NTI is not up and down: annexation one up and down

----UAI group: left and right sides separation relation Si and----WDW gives birth to: left and right sides annexation-_----JEW prisoner: surround separation relation mouth people----OVY entirely not: semi-surrounding annexation Bao -----CJY farming: direct cross reference Mi

----Zheng CGY: non-standard about three relations

Big Fu----KKPW chats: non-standard about three close attaching lug Jie----GGPW eggplant: three upper and lower relation Lv power mouths----HCOI happiness: three upper and lower relation scholars ----FROI hugs: about three of standards concern Rolling rice woman----KMQH cup: about three of standards are closed chain timbers one to mouth

----the TUAH garden: three are surrounded relation mouthful two youngsters, and----OUYY is far: three encirclements concern the Chuo edge of a knife, and--------FVVY's ZCOY witch: three nest relation workman people hangs down: three cross reference thousand Lv two----FHFY

It should be noted that sign indicating number directly perceived irrespectively handles encirclement or nest with the custom order of strokes observed in calligraphy as the initial workpiece of this word, it is unified in proper order to have reached encirclement or nested type-word code fetch.For example:

Store up: OUMY prolongs: ZJHY builds: ZEFY

(4), supply sign indicating number

Sign indicating number directly perceived is supplied sign indicating number (G) in order to make the code length unanimity, to have set.Supply sign indicating number and only appear in two word codes, be used in the 4th, promptly behind the font sign indicating number.For example:

As: QOWG chicken: QSWG

(5), individual member word

Sign indicating number directly perceived becomes word to be divided into two classes individual member: to shape and 25 higher words of key letter shape approximation degree, with the pattern-coding of " part sign indicating number+YYY ".They are:

Little day cutter order Wang worker jin twenty factory

AYYY BYYY CYYY DYYY EYYY FYYY GYYY HYYY JYYY

Several mouthfuls of corpse of big words pawl chi again are own

KYYY LYYY MYYY NYYY OYYY PYYY QYYY RYYY SYYY

11 people, the one seven bifurcation second

All the other unified pattern-codings of TYYY UYYY VYYY WYYY XYYY YYYY ZYYY with " the first sign indicating number+segmentation tail sign indicating number of the whole sign indicating number+Y+ segmentation of member ".As: power: CYZJ tooth: GYGJ woman: QYXU: ZYZU

(6), phrase coding

In order to improve input efficiency, sign indicating number directly perceived has adopted phrase condensation coded system, and code length is four yards with the individual character code length.The phrase coding mode is as follows:

Two words: get the sign indicating number first of two words first successively.As

Build: ZE (FY)+LN (QH)-→ ZELN

Motherland: UD (WH)+OE (LY)-→ UDOE

Three words: get first yard and the sign indicating number first of last word of two words first successively.As

Computing machine: L (TWG)+M (DHI)+TN (WG)-→ LMTN

TV station: B (LYG)+U (RWG)+QO (IG)-→ NUQO

Multi-character words: the above speech of four words and four words is a multi-character words.Coding is got the first sign indicating number of three last words first successively.As:

Keep on improving: M (ENH)+K (VDI)+U (ALY)+M (ENH)---→ MKUM

National economy: O (ELY)+P (XYH)+W (QFH)+I (QJH)---→ OPWI

The Chinese Communist Party: O (IYG)+O (ELY)+H (VIG)+A (COY)---→ OOHA

(7), brevity code word

One-level brevity code word:

Sign indicating number directly perceived 26 monosyllabic words the highest to frequency of utilization are provided with one-level brevity code input method.Their correspondence code has plenty of the first sign indicating number of having got all-key, the need associative memory that has.

Got radicals by which characters are arranged in traditional Chinese dictionaries sign indicating numbers:

Be,, big, say, one, the people,, this, also, arrive;

B F K L U V X Z E Q

Association determines according to the Chinese character local shape:

Individual, can, want,,, last, I,, go back, have,

A C D S G H I J M N

With, all, just, or not come.

O P R T W Y

Two, three word:

Not ad hoc two, the three word of sign indicating number directly perceived.1., Chinese character is as the frequency of monosyllabic word but because the order that all Chinese characters appear in the presenting bank in the sign indicating number directly perceived is determined jointly by following three factors:; 2., Chinese character is formed plain total frequency as monosyllabic word and speech; 3., the coded sequence of Chinese character in code plan directly perceived.So appear at the primary secondary simple code Chinese character that just is equivalent to of presenting bank after hitting two keys, appear at the primary three word that just is equivalent to of presenting bank after hitting triple bond.

(8), two word segmentations

In order to improve the coding hit rate, sign indicating number directly perceived is provided with second kind of segmentation encoding scheme to hundreds of two words.Its principle is:

1, typical Chinese character radicals spare is no longer segmented.They are: Xin day Mi Http order The wide Rolling Yan of _ Jin Lv Rui factory _ moon mouthful Fu woman

Worm stone wood Woo Yi Ren Si Quan fire Chuo Yin

2, some members are segmented by demarcating rule, change two words into three words or four words (except the situation of the work typical case radicals by which characters are arranged in traditional Chinese dictionaries of pointing out above).For example:

In vain: Pie day dies: the Dian Contraband and:

One ninth of the ten Heavenly Stems: Pie scholar's soil: 11

JB LC NU JF TU tooth:

Pie

Ha is good: blunt cun of Dian:

Dian: one

GJ JV LR TL ZU it should be noted that member no longer segments in the phrase.Subdivision rules sees Fig. 2 A, B for details.

(9), non-word character code

36 non-word character codes in the GB Chinese characters of level 2 are as follows:

1, solid size character: II+ package code+G

As: Xin--IIAG Dao--IIJG Si--IIWG

2, the first sign indicating number+tail sign indicating number of dicode character: II+

As: among Cannibals-IICL Nie-IIEI-IIUI

(10), non-basic building block splits

The fractionation of non-basic building block sees also Fig. 4 A, B.

(11), conventional sign input method

For convenience of the user, sign indicating number directly perceived is provided at the coded system of directly importing conventional sign under the half-angle state:

The most frequently used Chinese writing symbol is definite with the pattern of " associative memory sign indicating number+W ", as:

。----OW, the correspondence code input of other symbol of----QW (comprising several literal commonly used) available respective specific sign field.

The present invention compares with existing Chinese character entering technique, has following obviously excellent (spy) point:

1, adopts the method for shape holder directly perceived, shape and the directly true fixed key position of the same or similar relation of key letter shape according to the Chinese character basic building block, without any need for conversion of shape sound shape or partition location process beginner,, just can not see instructions input Chinese character through the study of several hrs;

2, the common ground that is arranged between the Chinese character member on the same keys position in shape is fairly obvious, is convenient to association, and easily note is not forgotten;

3, do not destroy the integrality of HF components as far as possible, reduce the difficult code fetch difficulty that member causes of tearing open;

4, following with the tradition Chinese character radicals by which characters are arranged in traditional Chinese dictionaries is the principle at center, and the Chinese characters in common use radicals by which characters are arranged in traditional Chinese dictionaries are demarcated with solid size or dicode without exception;

5,, determine the font of Chinese character, and, be provided with one simultaneously and supply sign indicating number with four fixing font representation according to the relative position between the member.Font sign indicating number and to supply the probability that sign indicating number closes with the part code weight minimum;

6, taked the word frequency word of Chinese character frequently to determine the fuzzy search mode of Chinese character DISPLAY ORDER jointly, made things convenient for the user with the sign indicating number preface;

7, a hundreds of word is provided with two kinds of schemes of rough segmentation and segmentation, to be fit to user's different skill levels;

8, Chinese character input method provided by the invention, not only easy to learn, reach very high hit rate simultaneously: the GB first-level Chinese characters repetition rate of coding is 2.6% in the holotype scheme, and total rate of dynamic coincident code is 4/10000ths.So, remember I and II (etc.) after the brevity code word, the user can reach very high input speed;

9, the conventional sign partition is clear and definite, and input method is simple, and is easy to use.
