Abstract

D2-A sign indicating number is a kind of new computer Chinese character input technology, it is pure shape two-dimensional Chinese character, because Chinese character is divided into level Four: the form of a stroke or a combination of strokes, pen-shaped structure, radical, individual character, decide slogan banner with nine class pen-shaped structure, with the vertical surely mark of the three class forms of a stroke or a combination of strokes, make the sign indicating number of coordinate in length and breadth of parts thus, and it is corresponding with the key position with parts to press the mode of two dimensional surface coordinate, thus relaxed encode Chinese characters for computer easily learn (rule is few) with easy-to-use (code length is short, the key position less, the repetition rate of coding is low) contradiction.

D2-A sign indicating number without the word sound, has realized that the character code code length of whole 6763 Chinese characters among the GB2312-80 is no more than 3 with less rule on 27 base key positions, rate of dynamic coincident code is about 1%, and maximum 3 words are heavy mutually.

Description

Technical field: computer Chinese character input technology.

Prior art: encode Chinese characters for computer at present is existing hundreds of, because parts are all corresponding by the mode of one-dimensional sequence with the key position, therefore is referred to as the one dimension encode Chinese characters for computer.Except that the pure tone sign indicating number, other font codes or phonetic-stroke code all are divided into Chinese character three grades: the form of a stroke or a combination of strokes, radical, individual character and with the form of a stroke or a combination of strokes or the radical basic element of character as coding.I at first proposed the principle (See Attachment 1) of two-dimensional Chinese character in 1985, its principal character is that Chinese character is divided into level Four: the form of a stroke or a combination of strokes, pen-shaped structure, radical, individual character, with the basic element of character of pen-shaped structure as coding, adopt in length and breadth two cover rules to make the sign indicating number of coordinate in length and breadth of parts, and keyboard is considered as planimetric coordinates makes the key position corresponding with parts.Around this principle designed the first cover two-dimensional character encode Chinese characters for computer-sound shape coordinate input method (being called for short YXB).After this designed another set of pure font code CXB with pen-shaped structure as the basic element of character again.This two cover is realized by computer software center, Beijing, and is tested and appraised (seeing Appendix two) in April, 87.

Goal of the invention: encode Chinese characters for computer is easy to learn and use more.

Summary of the invention:

(1) keyboard Designing is with reference to figure one.

Illustrate: the function of P key is character code covers such as number (seeing 3);

The function of P1 key is the conversion (seeing 6) of speech sign indicating number;

The function of P2 key is to handle second repeated code and brevity code symbolic code cover (seeing 7);

The function of space bar is to handle first repeated code and character code cover.

(1) fixed sign indicating number rule (with reference to subordinate list 1).

Two-dimensional Chinese character D2-A has horizontal vertical two cover rules, and laterally rule is fixed by pen-shaped structure, and pithy formula is:

Single one, two pens two, triangle three, square four, orthogonal five, oblique six, right angle seven, the people eight or eight, three nine.

Vertically rule is fixed by the form of a stroke or a combination of strokes or stroke count, and pithy formula is:

Cast aside straight horizontal stroke by point, horizontal stroke puts two always; The folder Eight characters is colluded in left-falling stroke, and vertical mark is got and done three, four five six seven nine, also will see horizontal number.

Illustrate with for example:

11（Q）

(1) independent horizontal stroke, as extend (up and down), dawn (descending);

(2) under (on) face is connected with one horizontal stroke, as the king (on), just (on), stone (on), page or leaf (on), give birth to (descending), lining (descending).

(1) mouthful word, as only (on), ancient (descending);

(2) corpse word (band cast aside mouth), as chi (on), eyebrow (on), institute (lower-left).

53（B）

(1) cast aside the orthogonal of the first stroke of a Chinese character, as ox (on), accuse (on), Zhu (on), system (upper left);

(2) hand over three times orthogonal with horizontal pen, as rich, then (on), table (on), sheep (descend), by (on), first (descending), Shen (up and down), electric (on), fork-like farm tool used in ancient China (on);

(1) right angle cast aside of band, as with (on), month (on), week (on), sentence (on), power, an ancient type of spoon, several, wind (on);

(2) hand over three times right angle with horizontal pen, as electricity (descend), tortoise (descending), all of a sudden (descending).

83（＜）

(1) herringbone (including), as gold (on), from (about), modern (on), make (on), day (descend), big (descending), fiery (descending), the last of the twelve Earthly Branches (descending), (descending), chi (descending) of a specified duration;

(4) hand over three times little with horizontal pen, as fork-like farm tool used in ancient China (descending), grasp (descending);

(5) rice word is as card (descending), rice (up and down), next (descending).

Number one, two, three, four, five, six, seven, eight, nine corresponding to nine key positions (P key cover) of first row, is not exclusively pressed above rule successively.As one: 11P, two: 21P ... nine: 91P, the capitalization number is respectively one: 11 11P, two: 21 21P ... 9 91 91P, ten to regard 5 * 2 code fetches as be 52P.

Slogan banner is 5,6,7,9 o'clock, and by determining with the intersection number of horizontal pen, but independent horizontal stroke can not add up to the horizontal stroke that turns round during vertical indicating, and for example following yard of fork-like farm tool used in ancient China is 93, and last sign indicating number is 53, but following yard of restrainting is 92, and last yard is 52.And for example following yard of hair is 72, but following yard of collecing is 51.

(3) monomer word code fetch rule

The individual character that the monomer word promptly is made of radical and radicals by which characters are arranged in traditional Chinese dictionaries.Can see that from a last chapter most monomer words are only got two yards up and down, need not tear root open, this is a principal feature of two-dimensional Chinese character.For the fairly simple monomer word of some forms of a stroke or a combination of strokes, when getting up and down sign indicating number, the form of a stroke or a combination of strokes that has is public possibly.Upward sign indicating number as  is that 71 times sign indicating numbers are 31; Big upward sign indicating number is 61, and following sign indicating number is 83, and the upward sign indicating number of Jiong is 72, and following yard is 23; The upward sign indicating number of wood is 53, and following sign indicating number is 91; The upward sign indicating number of towel is 51, and following sign indicating number is 31.Otherwise for the monomer word of some form of a stroke or a combination of strokes more complicated, middle part may be omitted and be disregarded, and for example heavy upward sign indicating number is 82, and following sign indicating number is 11; The upward sign indicating number of thing is 52, and following sign indicating number is 32.Just class hour can not be as the one dimension encode Chinese characters for computer, they is taken apart get 3 yards.Following monomer word is only got one yard:

With having of P key cover digital one 11,2 21,3 31,4 41,5 51,6 61,7 71,8 81,9 91,10 and mouthfuls 43, order 42, ox 53, foretell 62, several 72, river 92, pawl 93.With the space bar cover have worker 11,31, day say 41, native scholar 51, again 61, factory 13, wide by 23, in 52, justice fork 62, youngster 72, water 92, rich 53, power an ancient type of spoon 73, people go into 83, little by 93.Radicals by which characters are arranged in traditional Chinese dictionaries have Rui 91, Bing 81, Epileptic 23, Ren 82, Http 32, Rolling 62, Lv European-allies 22, Chuo 72, Xin 92, Quan Fan 63.

Therefore because the maximum code length of character code is 3, gets two yards and still get one yard and all need the cover could short in size.Character code cover generalized case space bar, below several situations with P key covers:

(a) number; One, two ... nine and capitalization, ten, hundred, thousand, ten thousand, several, single, double, two, altogether;

(b) Heavenly Stems and Earthly Branches; First, second, third, fourth ... sub, ugly

(c) human organ: mouth, order, tongue, ear, body, hand, foot, blood, meat, bone, skin, hair, send out, the heart, head, head, pawl;

(d) animal: ox, horse, sheep, deer, dog, dragon, fish, worm, bird, mouse, tortoise, tiger;

(e) personage: father, mother, brother, younger brother, husband, wife;

(f) direction: East, West, South, North, up, down, left, right, before and after;

(g) weight length: jin, two, gram, chi, very little, zhang;

(h) contain door, Bao, Chuo, shoot a retrievable arrow, river, Nie, fore-telling, two yards individual characters.

(4) code fetch of binary word.

The individual character that the binary word promptly is made of two radicals, about branch with two kinds of structures up and down:

(A) left and right sides structure

(a) be single codeword as two bodies, then get two yards from left to right, then cover.For example, converge 91 71, pounce on 62 62P, tear 91 42, only 82 61, grab 62 93P;

(b) be that another body of solid size is a dicode as one, then get trigram in the direction of the clock from the upper left corner.As wash one's hair 91 53 91, change 62 33 83, letter 53 72 91;

(c) be dicode as two bodies, then get trigram in the direction of the clock, but radicals by which characters are arranged in traditional Chinese dictionaries are only got one yard.

(figure two a), for example, branch 53 52 61 carries 71 61 83 on the back when radicals by which characters are arranged in traditional Chinese dictionaries during on a left side;

When radicals by which characters are arranged in traditional Chinese dictionaries during on the right side (figure two b), for example, push up 11 11 32, duck 42 13 53.

(B) up-down structure

(a) be solid size as two bodies, then get two yards up and down successively, then cover.As dirt 93 51,41 52P early;

(b) be solid size as one is arranged in two bodies, another body is a dicode, then gets trigram by the order in up and down.For example cottonrose hibiscus 22 83 62, lane 11 22 51, point 93 83 61;

(c) be dicode as two bodies, then get the sign indicating number of going up of upper body successively, following yard of lower body, and then get another yard of non-radicals by which characters are arranged in traditional Chinese dictionaries.

As radicals by which characters are arranged in traditional Chinese dictionaries (figure two c) when last, for example, how 61 93 21, need 11 22 11.

When radicals by which characters are arranged in traditional Chinese dictionaries at following time (figure two d), for example, suffer from 52 71 52, moxibustion 33 83 83.

(C) about all the other structures are converted to without exception or up-down structure:

(a) inside and outside: for example, about 42 83 61();

(b) go up bag: for example, with 72 41 23, wind 73 63 is about salty 91 41 13();

(c) wrap down: for example, connect about 61 72 52();

(d) left side bag: for example, distinguish 71 63, about huge 71 42();

(e) upper right bag: for example, take charge of 71 41, sentence 73 43 31, or 91 41 63, cut out 91

About 91 63();

(f) upper left bag: for example, bed 23 91 53 is about room 42 31 21().

In the binary word, all can be used as radicals by which characters are arranged in traditional Chinese dictionaries as two bodies, then everyday character all has two kinds of input methods.For example glad, code fetch is that 13 33 83(left side jin are made radicals by which characters are arranged in traditional Chinese dictionaries), or radicals by which characters are arranged in traditional Chinese dictionaries are owed to do in 13 33 12(the right).And for example season, code fetch is that 82 53 31(top standing grain are made radicals by which characters are arranged in traditional Chinese dictionaries), or the following son of 82 53 91(is made radicals by which characters are arranged in traditional Chinese dictionaries).

(D) for some fairly simple binary words (the particularly trigram left and right sides structure of up-down structure and radicals by which characters are arranged in traditional Chinese dictionaries on the left side) of the form of a stroke or a combination of strokes commonly used, all are furnished with two key brevity codes.For example call 71 43 together, number 43 31P entrust 82 63 and 82 43, weigh 53 61, and 53 42P blame 53 82 mutually, and sharp 82 23, other 43 23.The user can in use grasp (these words may be repeated codes as get trigram by rule sometimes) gradually.

(5) code taking rule of many bodies word

Form by three or three above radicals as an individual character, be to get trigram in the direction of the clock from the upper left corner in principle, but each radical got one yard at most, and follow following rule:

(A) in the elder generation back down, earlier the left back right side, earlier in the outer back;

(B) last upper and lower down, on.

On on the what is called, promptly Shang Mian radical is got sign indicating number; Following, promptly Xia Mian radical takes off sign indicating number; In on, promptly Zhong Jian radical is got

Last sign indicating number.Many bodies word mainly contains following several types:

(a) for example (figure three a) sets 53 61 53, macerates 91 71 63, and little 23 92 13;

(b) for example (figure three b), auspicious 11 92 22, compile 33 42 22, mallet 53 13 72;

(c) for example (figure three c), money 51 33 93 inscribes 41 11 83, and new 21 13 91;

(d) for example (figure three d) console 43 53 71, keep away 43 21 72, a little 12 73 21;

(e) for example (figure three e) penalize 42 23 31, and place 32 41 82 carries out 43 63 82;

(f) for example (figure three f), close 32 72 91, be willing to 13 71 13, fluffy 22 72 63;

(g) for example (figure three g), pattern 53 31 41 fires 93 32 92, slips 91 13 42;

(h) for example (figure three h), rod 53 41 73 changes 91 83 23, chews 43 93 32;

(i) for example (figure three i), Fan 53 63 83, territory 13 61 81, pocket 13 13 72;

(j) for example (figure three j) win 21 82 82, bind round 81 31 71;

(k) for example (figure three k), rate 21 52 81, swallow 22 92 62;

(l) for example (figure three l), aster 22 71 32, castor 22 73 13.

(6) speech sign indicating number

Two-dimensional Chinese character D2-A is composed of about 10,007 over thousands of of speech sign indicating numbers, by the conversion of P1 key, in the following several ways.

(1) bisyllable

(1) first word is that monomer structure or top have only a radical, gets the sign indicating number of going up of first word earlier, hits the P1 key then, get second word again preceding two yards.

For example, the 11P1 11 11 that happens to, undisguised 1,1P1 72 21, possible 1,1P1 33 73, minimum 4,1P1 82 13;

(2) top of first word is a left and right sides structure, get first word earlier preceding two yards, hits the P1 key then, get second word again first yard.But as second word also is left and right sides structure and identical with the radicals by which characters are arranged in traditional Chinese dictionaries of the word, and then second word got second yard.

For example, short commentary 13 4,1P1 72 come and go 23 2,1P1 13, organize 33 4,1P1 43, and stair 53 9,3P1 81 weigh 23 3,3P1 41, help 63 3,1P1 41.

(3) special case

(A) as first word for down, the back, or not do not have first yard following yard of getting these words respectively then.

For example, back 4,1P1 11 42, whereabouts 6,2P1 22 43, continuous 9,3P1 93 13, shameless 7,2P1 12 12.

(B) radicals by which characters are arranged in traditional Chinese dictionaries as first word are factory's (comprising), Chuo and bamboo prefix, and then previous word is got two yards (handling equally with up-down structure).

For example, centimetre 13 1,1P1 93, reaction 13 6,1P1 21, reason 81 7,2P1 11 wait for 81 3,2P1 23.

(2) three-phoned vocabulary

Hit the P1 key earlier, each word is respectively got first yard successively then.

For example, vice-premier P1 41 81 11, sorry P1 61 93 51, lertter of introduction P1 83 33 82.

Attention: down, the back, or not do not have and still take off sign indicating number (down with).

(3) four sound speech

Hit the P1 key earlier, get successively then first, second, first yard of the 4th word.

For example, natural P1 11 13 32, the P1 of the proletariat 72 21 33, scientific management P1 82 91 11.

(4) polyphonic word (five notes of traditional Chinese music or more than the five notes of traditional Chinese music)

Hit the P1 key earlier, get first then successively, the 3rd and first yard of the last character.

For example, the P1 of the Chinese Communist Party 52 22 92, collective ownership P1 82 13 53, the P1 of political consultative conference 11 52 72, the P1 of the People's Republic of China (PRC) 52 83 42(are for fear of repeated code, the minority polyphonic word is not according to above rule code fetch, and the user can in use grasp gradually

(7) brevity code, specific code, symbolic code

(A) brevity code

As should getting trigram, but in fact only get two yards or one yard by rule; Perhaps should get two yards, but in fact only get one yard word or speech, all be called brevity code by rule.The main effect of brevity code is:

(1) reduce repeated code, some everyday character then is a repeated code as get trigram by rule, but as getting preceding two yards, may not be repeated code then.For example, should be 53 42 91 by regular code fetch, at this moment be repeated code, but as get brevity code 53 42 P, then be not repeated code.

(2) some everyday character is not a repeated code, but in order to improve input speed (only getting a yard or two yards), is furnished with corresponding brevity code yet.For example, this should get 21 72 63(by rule is not repeated code), but owing to, therefore be furnished with brevity code 21 through commonly used.

Brevity code can be used space bar, P key or P2 key cover, and during with P2 key cover, solid size is a character code, and dicode is the brevity code of speech.

For example, correct 11 11P2, international 42 31P2,83 23P2(of the People's Government get head and the tail first yard of word).

(B) specific code

Allly be specific code not according to regular code fetch person.The main effect of specific code is:

(a) reduce repeated code, for example, face by regular code fetch and should be 22 81 41, this and prison are repeated codes, as adopt another sign indicating number 22 81 42, then are not repeated code (this specific code are few in number, and all is the vertical mark of last yard of change).

(b) pen-shaped structure of some Chinese character is mistaken easily, so be furnished with specific code.For example the code fetch of lung should be 73 52 31, but has the people that its mistake is written as lung, therefore is furnished with specific code 73 21 31.

The user has grasped (about 150) after these brevity codes and the specific code, can accomplish that everyday character almost do not have repeated code, and the dynamic average code length of pure character code can drop to below 2.8.But these brevity codes and specific code and need not memorize mechanically, first class hour the repetition rate of coding may be higher, repeated code occurs as everyday character and will find out corresponding brevity code or specific code, just can grasp naturally through exercise after a while.

(C) symbolic code

Two-dimensional Chinese character D2-A has three cover symbolic codes (all with P2 key cover).

(a) punctuate commonly used: hit any in 27 base key positions earlier, hit then 93(＞) key, hit the P2 key at last.

For example,? number correspondence code be that 72＞P2(has only comma, and fullstop.Be respectively 92P and 93P).

(b) the small letter Latin alphabet: hit any in 27 base key positions earlier, hit 92(L then) key hits the P2 key at last.

For example, the correspondence code of a is 12LP2, and the correspondence code of s is 22L P2, and the rest may be inferred by analogy.

(C) common mathematical symbol: hit any in 27 base key positions earlier, hit 52(G then) key hits the P2 key at last.

For example, the correspondence code of ∑ number is 73G P2.

Compared with prior art.

(1) compare with the one dimension encode Chinese characters for computer:

(A) easily learn.Except that phonetic sign indicating number and stroke shape Chinese code, all one dimension encodes Chinese characters for computer are all with the basic element of character of radical as coding, the user generally will remember more than 100 coding radical, can divide into groups by certain mode though (for example 5-stroke shape code ' is to be divided into five groups by the first stroke of a Chinese character) that has, but radical and key position in each group there is no unified correspondence rule, and also will tear root open to some non-coding radicals, so user's memory capacitance is big, is difficult to grasp.

The D2-A sign indicating number is to be the two-dimensional Chinese character of parts with the pen-shaped structure, the user need not remember that radical also need not tear root open, as long as remember the nine class pen-shaped structure and the relevant form of a stroke or a combination of strokes, just can find the pairing key of each parts position by the corresponded manner of two-dimensional coordinate, therefore memory capacitance is little, more easily learns.

(B) the key position less, code length is short.Up to now, all one dimension encodes Chinese characters for computer, the base key position less than 30 condition under, it is lower to desire the repetition rate of coding, the maximum code length of character code is at least 4; Otherwise, desire is compressed to 3 with the code length of character code, and then the base key figure place is at least more than 40, and the base key position of D2-A sign indicating number is 27, but the maximum code length of character code only is 3, and keep the lower repetition rate of coding (rate of dynamic coincident code be about 1% and maximum 3 words heavy mutually).

(2) compare with YXB, CXB.Though YXB is a two-dimensional Chinese character, because vertically rule is determined by the word sound, whenever hit a key and all will consider sound and shape, the two can not be unified forever, therefore just easily learn, but input speed can not improve.

Though CXB is pure font code, and with the basic element of character of pen-shaped structure as coding, because ununified vertical rule, rule is more, is difficult to grasp.

The D2-A sign indicating number combines the strong point of the two, overcome deficiency separately, because it has by the unified vertical rule determined of the form of a stroke or a combination of strokes, therefore learning difficulty is low, two cover rules are definite by font in length and breadth because of it again, therefore can make the two unification after being familiar with, as the one dimension encode Chinese characters for computer, directly look for key bits corresponding fully, therefore can obtain higher input speed by parts (pen-shaped structure).

Can consult subordinate list two (the one dimension font code is representative with five pen type sign indicating numbers) about the difference of D2-A sign indicating number and other input method.

3) the D2-A sign indicating number is now realized on similar types such as IBM-PC and Great Wall 0520, and ready-made software is arranged.After tested, rate of dynamic coincident code is about 1%, and maximum 3 words are heavy mutually.Can realize as long as program is done suitable adjustment for other types.Need as the user, whole code books of character code and speech sign indicating number can be provided.

Claims (2)

1, preamble: existing encode Chinese characters for computer majority is the one dimension encode Chinese characters for computer, and its common trait is: (1) is divided into three grades with Chinese character: the form of a stroke or a combination of strokes, radical, individual character, with the form of a stroke or a combination of strokes or radical the basic element of character as coding; (2) parts are corresponding by the one-dimensional sequence mode with the key position.

Though the YXB sign indicating number is a two-dimensional Chinese character, vertically rule is determined by the word sound, though the CXB sign indicating number is a pure font code of making parts with pen-shaped structure, and ununified vertical rule.

2, characteristic: the D2-A sign indicating number is a two-dimensional Chinese character, it is characterized in that: (1) is divided into level Four with Chinese character: the form of a stroke or a combination of strokes, pen-shaped structure, radical, individual character, with the basic element of character of pen-shaped structure as coding, (2) with the horizontal rule of nine class pen-shaped structure as unification, with the vertical rule of the three class forms of a stroke or a combination of strokes as unification, make the sign indicating number of coordinate in length and breadth of parts thus, it is corresponding with the key position to press the two dimensional surface coordinate.
