Description

Optimize the Five-stroke Method compiling method and keyboard thereof

Computing machine is in the widely used significant obstacle of China, and promptly Chinese characters in computer is imported problem, is called as the bottleneck of Chinese information processing.And how to adopt 26 letter keys of the original-pack keyboard of computing machine, and finish the pure character shape coding of ten hundreds of Chinese characters and vocabulary, and design the high-effect Hanzi input keyboard of easily learning directly perceived, then be considered to the great difficult problem in China's information revolution.

Before and after in 1978, domestic popular Pinyin coding or phonological and calligraphical syn thesize coding, all less based on Chinese phoneme, simple these characteristics of Chinese-character pronunciation.Though can use QWERTY keyboard, China is vast in territory, how assorted dialect is, and people are not familiar with or read to be forbidden the word of sound a lot, thereby the processing number of words and the usable range of this class scheme all are restricted.

Pure pronunciation mode, too many because of the Chinese character phonetically similar word, need constantly on screen, to select and could import, can not accomplish only to see that original copy do not see the quick touch system of screen, thereby efficient is very low, per minute generally can be imported 10-20 Chinese character.

Sound shape combined techniques often needs to be grasped two kinds of factors of pronunciation and font, and its design generally more finds it difficult to learn and practises and use.

The whole big keyboard method of word not only needs to manufacture specialized equipment, increases system cost, and several thousand Chinese characters confront, and looks for the word difficulty, and efficient is lower.

The happy elegant sound professor of Hong Kong Chinese University had delivered the pure character pattern input scheme of using 256 key positions (keyboard special) in 1981.Almost simultaneously, there is the triangle coding of U.S. Wang An company to come out again.The domestic 60 key keyboard special schemes that the Zhang Qijun of Yunnan University professor is then arranged etc.These designs all need to manufacture special Chinese keyboard, thereby system cost is increased, and are difficult to penetration and promotion on existing machine.

26-36 key of use QWERTY keyboard finished the pure character pattern input of Chinese character, then is the higher target that domestic and international researcher pursues.

Use 26 keys again than using the be more convenient for touch system and improve input efficiency of 36 keys.

Taiwan Acer had released " day imperial letter input method " in 1982, can use 26 letter keys to handle Chinese character.But should invention further investigate owing to the regularity to Chinese character lacks, the distinct rule of divining by means of characters is difficult to be accepted by the people with writing.As: " order " splitted into be " ", " power " is splitted into be " " etc., it also lacks the integrated application of multi-subject knowledge (such as the application of biomechanics in coding and keyboard Designing) simultaneously, thereby regular numerous and diverse, and code length is longer.The surface memory factor seldom, actual memory factor is a lot.Make the exception coding such as the word that has 5%.In addition, this technology does not solve the word handling problem yet.Therefore, " day imperial scheme " and keyboard Designing thereof are difficult to move towards large tracts of land practicability, in fact do not solve the pure shape computing machine input problem of Chinese character well.

And " optimization the Five-stroke Method " compiling method and keyboard thereof, then more than 10,000 Chinese characters are being split one by one, several ten thousand cards are carried out after the statistical study, " Chinese character root group word frequency table " and " the practical frequency table of Chinese character root " at first proposed, for stroke, radical, the font of Chinese character have been stipulated definition accurately in the world.When 130 kinds of radicals that optimize are drawn the upright sequence of establishment according to the shape classification, again according to key position probability and fingering requirement, 25 letter keys such as A-Y are carried out partition divided the position, make each corresponding key position of group radical, thereby, be designed to a Chinese word root keyboard of easily learning directly perceived with an original-pack QWERTY keyboard of computing machine.Utilize the radical of this keyboard, can be combined into nearly 7000 Chinese characters and thousands of (not limitting) Chinese vocabulary easily as writing." Z " key outside the radical key gives over to motor-driven, can replace operator's ignorant any radical for the moment, carries out the study of man-machine conversation formula input method.

This invention provides " five kinds of strokes " to reach " word-root spelling form " two kinds of input methods.The former has the ten minutes short-term effects that can learn, and the latter then has per minute can import the high-level efficiency prospect at a specified future date of 150 Chinese characters.Therefore no matter the present invention is for sole duty or non-full-time operating personnel, all quite easily learn, easy note, easy-to-use, thereby, make the Chinese character entering technique of computing machine really move towards practicability.

The present invention relates to a kind of a kind of input in Chinese keyboard of optimizing the Five-stroke Method compiling method and designing according to this method, its characteristics are complete font information according to Chinese character, take the mode of five kinds of strokes or word-root spelling form, realize the high-level efficiency input that Chinese character and Chinese vocabulary are easy to learn and use.The present invention is applicable to that all are large, medium and small, microcomputer Chinese information processing system and communication system, and will obtain widespread use at aspects such as Chinese terminal, Chinese fax, computer typewriter and computer Chinese-character typographical printings.

In the computer Chinese information disposal system, single Chinese character and Chinese vocabulary is the problem of input fast, be that all use the countries and regions of Chinese character to apply a difficult problem that presses for solution in the computing machine, the various coding methods of adopting in the prior art, the stroke code method is arranged, whole big keyboard of word and sound and shape combination coding, what have only is to encode in the basis with the stroke, what have only is to encode in the basis with the Chinese character root, and required radical is extremely many, do not have rule to receive the contact of finding out its inherence, thereby generally exist the key position many, need special-purpose input equipment, memory capacitance is big, complex operation, repeated code is more, shortcomings such as typing speed is low.

The present invention adopts the method for word-root spelling form group word, directly perceived easily learn, easy and simple to handle, words is compatible, input speed is high, is defined on the letter key of standard universal QWERTY keyboard through preferred some radicals, makes it to become a Chinese keyboard.Use this keyboard, can import up to ten thousand Chinese characters and thousands of Chinese vocabulary to computing machine, operating personnel key in the hand touch system, and per minute can be imported 120-150 Chinese character.The efficient of Chinese character input computing machine is greatly improved.

Optimize the Five-stroke Method compiling method and keyboard thereof Chinese character is considered as the spell shape literal, be divided into stroke, radical, whole three levels of word.Stroke is in conjunction with producing radical, and radical is combined to form Chinese character.Character shape coding is neither considered the pronunciation of Chinese character, also Chinese character is not all dismembered to be single stroke, but according to sequential write, be unit group word, group speech with the radical, and on the keyboard that is printed with radical and radical code, button is finished the coding input.

For realizing this encoding scheme, the present invention at first splits statistics to all radicals in ten hundreds of Chinese characters, the group word frequency that occurs in Chinese character according to each radical and its are in the sample survey of various newpapers and periodicals, magazine and books, the actual frequency that occurs screens, by preferred calculating to a large amount of radicals, with the radical classification of selecting, find out the group word frequency and the practical frequency of these radicals, constitute the important evidence of this compiling method.

And then the basic strokes that will form radical be summarised as horizontal, vertical, cast aside, press down, five kinds of foldings, wherein every kind of stroke all is to write trend by stroke, and similar stroke is summarized in together, for example rolls over class, be to incite somebody to action,, second,, these several multi-form tortuous strokes are summarised as one type, and according to the probability of use of these five kinds of strokes, order successively with arabic numeral code name 1,2,3,4,5, as Fig. 1.

In addition, according to the font characteristics of Chinese character, be four kinds of topology patterns with the font inductive generalization of Chinese character, promptly left right model, go up mo(u)ld bottom half, outer in type and haplotype.These four kinds of patterns are to divide with the position of the radical of the visual effect directly perceived of Chinese character and composition Chinese character.For example, the Chinese character of being made up of side by side left and right sides two parts or three part radicals of intuitively looking is classified as left right model,, speaks as the river, portion, the topology pattern of these several words of Hunan is,,.Every kind of font is ordered with arabic numeral 1,2 successively according to its frequency, and 3,4 as its font code name, as shown in Figure 2.

According to the height of group word frequency and practical frequency, by its mutual compatibility relation, merger is combined into five districts with the radical that optimizes, and each district uses 1,2,3,4,5 respectively, represents.Every district is divided into five key positions again, and with 1,2,3,4,5 represent the item of each key position respectively.Obtain 25 key positions like this.Every code of all using two arabic numeral as its position, place, as shown in Figure 3.Area code is consistent with the first sum of stroke code name of this district's radical; A general inferior stroke code name or the single number of radical with one's own department or unit radical of item is consistent.Formed a radical summary table like this, as shown in Figure 5.Wherein main characterized radical is arranged in the code key bitmap that has formed 25 groups of radicals on 25 key faces, and in each group, it is higher to select a usage frequency, and representational again radical is as the Chinese character key name.As shown in Figure 4.Be in the radical of same key position among the figure,, be called the coordination root as the isotopic element in the periodic table of chemical element.

With above-mentioned 25 groups of radicals selecting, be arranged on these 25 keys of A-Y on the standard universal keyboard according to the probability of use of every group of radical size and keyboard fingering custom, form a Chinese keyboard, as shown in Figure 6.

Be transformed into a Chinese character root keyboard for the ease of original-pack QWERTY keyboard, the present invention proposes a kind of method of economical and convenient, promptly print the radical Adhesive Label that adapts with keycap key face, be bonded at the keycap top active computer.On the label, existing Chinese character root has the English alphabet of former key position again.In addition, as the area code and the high frequency Chinese character of Chinese keyboard, then be bonded at the leading flank of button with less Adhesive Label.

The present invention is that unit keys in code to encode Chinese characters for computer or on keyboard with the radical by the Chinese-character writing order, maximum four yards of each Chinese character.The Chinese character of four radicals can be keyed in whole radicals by sequential write during input; When the radical number of Chinese character after decomposing surpasses four, only key in first, second, third and the radical in end.For example:

According to desirable: day, cutter, mouthful, Xiangxi

＜Jiangxi〉is desirable: upright, early, Fan, shellfish

To being less than the Chinese character of four radicals, when volume is got or keyed in code, should after its radical code, fill one " end pen and font intersection identification code ".This identification code is by an end form of a stroke or a combination of strokes code name of this Chinese character and the font code name be combined into of this Chinese character.As Fig. 7, when importing this and looking for yard, can on keyboard, find identical key-bit code, the promptly corresponding area code that becomes keyboard key-position.As many as append one with the same number of end of a type code name stroke radical.

For example:

＜Chinese〉got: (43), (54) again, a 41(end code name 4, font code name 1)

＜word〉got: (45), son (52), a 12(end code name 1, font code name 2)

＜this〉is got: wood (14), one (11), a 14(end code name 1, font code name 4)

As the Chinese character of key name, its input code is made a call to four times for this key connects, as:

Soil: it is F(12) key name of key, its code is FFFF(12,12,12,12)

Speech: it is Y(41) key name of key, its code is YYYY(41,41,41,41)

On each key position, itself be the coordination radical of Chinese character beyond those key name radicals, they be encoded to:

＜key-bit code 〉+＜the first sum of code 〉+＜second stroke code 〉+＜an end stroke code 〉

As:

＜side 〉: it is at Y(41) on the key, the first sum of stroke is " Dian " (Y, 41), and inferior stroke be " one " (G, 11), and a last stroke is " second " (T, 51).Its input code is YYGT(41,41,11,51)

The present invention is to all the haplotype Chinese characters beyond the character root of keyboard, and rule splits into maximum radical known on the keyboard by sequential write and keys in, and when this monomer word appears in the combinde rqdical character, only gets it at most and participates in coding by preceding two radicals that mentioned above principle splits out.For example:

One,, the people＜the third〉word splits the back radical and is:, its code is GMCO(11,25,34,44).Wherein 44 or the identification code of O when being four yards of less thaies.

＜smooth〉word splits the back radical: one, bow, people, and its code is GQCO(11,55,34,44).Wherein 44 or the identification code of O when being four yards of less thaies.

＜handle〉word splits the back radical: wood, one,, the people, its code is SGMC(14,11,25,34).

On each radical key, all arrange an extra high Chinese character of usage frequency, its input code is beaten for the place key and is added the lattice that fan the air, the one-level brevity code of meaning; There are 650 Chinese characters to adopt approximately only to get preceding two yards of its whole package codes to add and beat space bar input, the secondary brevity code of meaning; There are several thousand Chinese characters to adopt the preceding trigram of its whole package codes to add and beat space bar input, the three of meaning.Simultaneously, the all-key input mode with Chinese character of brevity code still keeps.

For solving the low problem of present encode Chinese characters for computer input speed, this compiling method has been created the Chinese word group according to the shape Methods for Coding, and method has thousands of the Chinese vocabulary codes of being made up of two or more Chinese characters as universal word according to this.In addition, also can enroll the common wordss of relevant specialty according to the needs in different business field.Vocabulary code is the consistent appearance that is total to the sign indicating number type of single word code.When arbitrary vocabulary code is imported, only need keystroke four times without exception.When vocabulary and the input of single Chinese character mixed and alternate, do not need to carry out any additional operations such as gear shift therebetween.Preceding two sign indicating numbers that the coding of two-character word is only got each Chinese character get final product.For example:

＜numeral〉two words are only got: rice, women, little, Http, and these four radicals, its code is OEIP(44,53,43,45).Three vocabulary that word is formed, it is encoded by first yard preceding two yards composition that add the 3rd Chinese character of the first, the second Chinese character, as:

＜operator〉this vocabulary, only get,, mouthful, shellfish, these four radicals.Its vocabulary code is BCKM(32,34,23,25).

Four vocabulary that word is formed, first sign indicating number of only getting each Chinese character gets final product, as:

＜encode Chinese characters for computer〉this vocabulary, only get,,, stone, these four radicals, its code is IPQD(43,45,55,13).

The vocabulary that the above Chinese character of five words is formed, the tool coding is by the first, the second, the 3rd and first yard composition of last Chinese character, as:

＜People's Republic of China (PRC)〉this vocabulary, only get mouthful,, people, mouth, these four radicals.Its code is KCCL(23,34,34,24).

The present invention provides 5,000 with interior universal word and coding thereof to the general user.The vocabulary that vocabulary facture of the present invention also can be used for all professional users expands.Its form style and universal word that expands vocabulary is identical.The professional user can by hand or use vocabulary additions and deletions software to finish the vocabulary expansion, and new term also is based upon in the system.The coding of newly-built vocabulary has 2% with the possibility of existing coding repeated code.To this, treating method has three kinds:

(1) cancels the vocabulary that wherein is of little use;

(2) wherein the long word remittance is divided into short vocabulary;

(3) must usefulness and the neologisms of repeated code, two yards modifications thereafter can be become LL, PP, SS, AA etc. form a kind of half definitions.LL wherein, PP etc. are called the definition suffix.Because in four encode series of the present invention, with LL, PP etc. can hold the outer sign indicating number of a large amount of definition for the space encoder of back two bit codes has very big redundance.

With above-mentioned compiling method repeated code word seldom.When the repeated code word occurring, generally do not influence typing speed.That prefix wherein commonly used is presented at earlier on the normal editor position of display line.If use this everyday character, can continue to key in hereinafter, this word just is presented on the normal editor position automatically; If use those words that are of little use, only need to press and the identical numerical key of the sequence number of this word in presenting bank, desired word can will be presented on the existing editor position.

In the process of Chinese characters for keyboard inputting, two kinds of alerting signals can appear; It is corresponding with it that short sound expression input code does not have word, promptly so-called idle bit, and cursor is motionless in the original place simultaneously; It is repeated code that sign indicating number is keyed in long sound expression, and can handle this moment by above-mentioned processing repeated code method.

Among the present invention, " Z " key on the Chinese keyboard gives over to motor-driven, when key feeding character, for the radical that is difficult to determine for the moment, available " Z " key that stays that gives replaces, only key in those confirmable radicals, the operator can select required Chinese character in the presenting bank of screen then, also demonstrates the correct coding of this Chinese character simultaneously.

Use 1,2,3,4,5 these five figure keys on the digital code keyboard, can key in arbitrary individual character and Chinese vocabulary equally by the position code of radical.

Be difficult for definite Chinese character for sequential write, the present invention allows by multiple order key entry, can both export same Chinese character.For example:

＜peach〉word can be SIX(14 by " wood,, youngster " code, 43,35) mode is imported; Can be SXI(14 by " wood, youngster, " code also, 35,43) mode be imported.

In order to overcome the difficulty that the beginner is familiar with key position, radical place and Chinese character fractionation, the present invention is designed to five kinds of stroke keyboards with the numeric keypad on Qwerty keyboard right side, promptly use numerical key 1,2,3,4,5 represent five kinds of basic strokes of Chinese character respectively: horizontal (one), perpendicular (), left-falling stroke (), right-falling stroke (), folding (second), and on the key face, print or be stained with the label of numeral and stroke, make it to become one group of five stroke key (Fig. 8).During with five stroke keys inputs Chinese character, only import first, second, third and fourth and the last stroke of Chinese character according to the book order, five strokes of persons of less than key in 0 as at interval.Be difficult to determine the stroke of its kind in the Chinese character, without exception with numerical key 6 replacement, after importing as stated above, meeting the Chinese character of importing the stroke sign indicating number will be presented in the prompt line of screen in batches.For example, when input during one, one, three stroke, will demonstrate 1 in the prompt line and do, 2 in, three words such as 3 Chus, and the sequence number that the operator can be as required keys in the Chinese character of wanting with numerical key be finished input.

Often repeated code is more to use five stroke input methods, selects number of times for reducing, and the present invention has adjusted key by Hanzi frequency count.Usage frequency reaches 40% Chinese character, all will be on first position with code word, and usage frequency accounts for 90% Chinese character, all will occur at first.

For making operating personnel utilize easy five strokes input to learn the Five-stroke Method character roots input method fast, after the input of five strokes,, all show the package code of their correspondences in the Chinese character back that presenting bank shows.

Under five stroke input states, the horizontal stroke on the word root keyboard (), perpendicular (), left-falling stroke (), right-falling stroke (), folding (second), promptly five letter keys of GHNYT have and the identical effect of digital stroke key.

Stroke proposed by the invention and radical system and input keyboard thereof, suitable equally to unsimplified Hanzi.At this moment simplify the body radical in the radical summary table and all change corresponding traditional font radical without exception, as: " " replaces with " speech ", can form a five-stroke character input method and the keyboard Designing (Fig. 9) that can handle unsimplified Hanzi.
