Description

Two stroke draw input method

The present invention relates to Chinese-character encode system for inputting.

Three major criterions weighing encode Chinese characters for computer are coding code length, the repetition rate of coding and learnabilities.Usually people always pay attention to encode code length, the repetition rate of coding, and ignore the learnability of encoding scheme; In order to reduce the coding code length and the repetition rate of coding, the big cover rule of laying down hard and fast rule artificially; Whether easily learn and ignore this coding, whether grasped by the masses easily.This way often causes its encoding scheme can not penetration and promotion, can only lay aside and neglect; This situation can be found everywhere in the input method of Chinese character field.It is too high that spelling input method is acknowledged as the repetition rate of coding, import too slow, yet because its learnability, the scope that spreads is wide, all is not comparabilities of those very complicated input methods more than the grasp number.

Along with the widespread usage of brevity code and vocabulary code, some coding code lengths can be imported Chinese character fast than long and the higher coding of the repetition rate of coding; One, two, three brevity code can cover and account for total word nearly 80% more than 500 high frequency word frequently, and vocabulary code can make the input of vocabulary reach 2 keys/below the word.Use brevity code and vocabulary code, improved input speed greatly.Under the situation that input speed is resolved, the emphasis of current encoder research should be the learnability of coding, i.e. coding rule summary meets people's cognitive law and thinking habit most, and the easiest people of allowing easily grasp.

Hanzi coding scheme can be divided into sound sign indicating number, font code, pronunciation-form combination code three classes.Sound sign indicating number class is easy to learn, but repetition rate of coding height, and the necessary orthoepy of grasping Chinese character; Inaccurate for phonetic, the personage that accent is heavier cannot use, and also can't import unacquainted word in addition.The pronunciation-form combination code class repetition rate of coding is low, but it also must grasp the orthoepy of Chinese character, and again Chinese character pattern is made respective rule, increased the difficulty of study, the more important thing is the thinking transfer problem that exists between sound, the shape, import the pronunciation (perhaps organizing word parts pronunciation) that should search for this word in the word brain, be transformed into very soon again and judge the font structure, decoding thought process is comparatively complicated.The font code class can be subdivided into two classes: radical class and order of strokes observed in calligraphy class.The group word parts of Chinese character reach more than 400 at least.The radical class is as the parts of coding at least more than 100, at most hundreds of.Radical class encoding scheme, the repetition rate of coding is lower, and input speed is very fast, but the word root memory amount is big, and radical corresponding keys position regularity is not obvious, all by memorize mechanicalling, does not often use and forgets easily.Order of strokes observed in calligraphy class is to encode by the stroke sequential write of Chinese character, and order of strokes observed in calligraphy class can be subdivided into two classes again: single is drawn class, two stroke class.Single is drawn for example Chinese character input method of stroke code of application number 97108865 of class, " five strokes " input method of 101 more common on the market input methods and Mr. Wang Yongmin; Stroke code is that 26 singles are drawn, and 101 input methods are that 10 singles are drawn, five strokes are that 5 singles are drawn, and all are by the pen input by the Chinese-character writing order.Single is drawn the class coding, and generally speaking rule is simple, but the coding code length is longer, repetition rate of coding height; Two stroke classes are meant that two singles are drawn and form a kind of pair of stroke, and modal is that traditional point-score by Chinese-character stroke is divided into horizontal, vertical, left, points, discount five big classes with Chinese-character stroke, and these five kinds of singles are drawn and are combined into 25 kinds pairs of strokes more in twos.Two stroke classes are because a key is imported two strokes of Chinese character, and the quantity of information that comprises is drawn big than single, so keeping under the simple characteristic of coding rule, coding code length, the repetition rate of coding all reduce significantly.Superiority just because of two strokes, in input method of Chinese character patented claim G06F 3/024 classification altogether in 1777, there are tens kinds based on the Hanzi coding scheme on two strokes basis, these encoding schemes add radicals by which characters are arranged in traditional Chinese dictionaries, first letter of pinyin, stroke identification code, tail sign indicating number means of identification one after another in order further to reduce coding code length, the repetition rate of coding.For example application number 98118166 two stroke codes have increased the high frequency radicals by which characters are arranged in traditional Chinese dictionaries, the decode key process that it makes the importer by " whole word--→ decompose stroke--→ button " change into " whole word--→ judge to have or not regulation radicals by which characters are arranged in traditional Chinese dictionaries (having radicals by which characters are arranged in traditional Chinese dictionaries preferentially to adopt radicals by which characters are arranged in traditional Chinese dictionaries)--→ decompose stroke--→ button ", prolong the thinking deterministic process, reduced learnability.Application number 97112888 stroke, shape, and hanyupinyings for example, increased pronunciation of the first letter, its coding rule is one, two, trigram is a stroke code, the 4th yard is pronunciation of the first letter, so just has the thinking transfer problem between a sound, the shape, such as " pen " word, the pronunciation that will reflect this word in the thinking earlier is " bi ", according to spelling input method, directly import " B ", " I " two keys, whole thinking deterministic process finishes.And in this sign indicating number, after phonetic is got pronunciation of the first letter, changing the font configuration aspects again over to, the thinking deterministic process prolongs; In addition, increase pronunciation of the first letter, require the user to grasp the Chinese character orthoepy, this two aspect has all reduced learnability.Application number 97120110 font code 5-key input methods for example, last sign indicating number has increased the stroke identification code, can be divided into two kinds: font identification code (up and down, about, heterozygosis), member identification code (discrete, connect, intersect), also increased the thinking deterministic process, reduced learnability.For example application number 97120110 double stroke codes are taked tail sign indicating number means of identification; Preceding trigram is pressed the order of writing strokes code fetch, and last sign indicating number jumps to last two code fetches; A lot of last two strokes of word can not identify at a glance, also need according to stroke order to determine, though technical increase stroke dispersion ratio helps reducing repeated code, whole thinking deterministic process prolongs, and does not meet people's writing style, has reduced learnability.For example application number 98123258 gold medal sign indicating numbers adopt simultaneously increases radicals by which characters are arranged in traditional Chinese dictionaries, first letter of pinyin, several means of identification of tail sign indicating number.Though more than these means of identification further reduced the repetition rate of coding, but increase and prolonged the thinking deterministic process, the thought process that causes decoding is complicated, reduced learnability, so this encoding scheme is under guarantee to encode code length and the unlikely too high prerequisite of the repetition rate of coding, do not adopt above these means of identification, make coding rule easily learn usefulness well.

With this encoding scheme more approaching be application number 97109184 double stroke codes, double stroke code adopts the identification of tail sign indicating number, trigram adds last two-stroke sign indicating number (tail sign indicating number) before getting, the relative merits front of tail sign indicating number is existing to be discussed, and no longer repeats; This sign indicating number requires two half-words all to draw above (containing four pictures) four handling discrete type (up and down, left and right sides structure), and preceding half-word is got preceding two yards, and back half-word is got first yard and tail sign indicating number; According to this rule, must determine earlier that latter half has and do not have four to draw above (containing four pictures), after could determining that first half has been got two yards, be to continue code fetch (trigram tailing sign indicating number) according to stroke order, still get the initial and end sign indicating number from latter half, do not meet people's writing style like this, increased the thinking deterministic process yet; In addition, double stroke code is not provided with the single partition, when Chinese character 8 draw in, with the situation that 1,3,5,7 strange strokes finish, this sign indicating number stipulates that last draws and one yard of picture second from the bottom composition, does not meet writing style like this, also increases repeated code.

The objective of the invention is to design a kind of extremely simple coding method, follow people's writing style fully, at utmost simplify decoding thinking deterministic process, the easiest of coding rule, the easiest people of allowing are easily grasped; Obtaining optimum balance aspect coding code length, the repetition rate of coding, the input speed simultaneously.

This encoding scheme adopts Chinese-character stroke tradition point-score that Chinese-character stroke is divided into horizontal, vertical, left, points, discount five big classes, wherein carries being classified as horizontal, vertical hook and being classified as perpendicular, right-falling stroke and being classified as a little, and a various foldings stroke is classified as folding; These five kinds of singles are drawn and 5 kinds of strokes are combined into 25 kinds of two strokes in twos and arrange on keyboard and form 5 two stroke districts and 1 single and draw and distinguish.The key position has been arranged under the simple and clear regularity of distribution prerequisite, (amount in 6447 words according to the frequency of utilization statistics according to " Chinese character stroke order quickly looking-up dictionary ", the first two stroke combination has more than 500 words: a Shu 1558 words, Shu 902 words, Pie one 554 words, Dian Dian 507 words), now define each stroke key of living in position: horizontal district: H (one by one) J (Shu) K (Pie) L (Dian); () perpendicular district: A (Shu one) S (Shu Shu) D (Shu Pie) F (Shu Dian) G (Shu ) casts aside district: Y (Pie one) U (Pie Shu) I (Pie Pie) O (Pie Dian) P (Pie ) some district: Q (Dian one) W (Dian Shu) E (Dian Pie) R (Dian Dian) T (Dian ) rolls over district: N ( one) M ( Shu), and ( Pie) ( Dian)/( ) single is drawn district: Z () X (Shu) C (Pie) V (Dian) B ()

(all in fingering under the control of the dexterousst forefinger, each district from left to right all is that horizontal, vertical, left, points, discount are arranged in above-mentioned four the most frequently used key positions)

This encoding scheme single character does not split, and combinde rqdical character is split as two parts by its font structure, up and down, about, about structure is divided into first half, latter half before and after writing by it; Upper, middle and lower, left, center, right structure, on it in, part is becoming to get under the word prerequisite greatly preferentially as first half in the left side, remaining part is as latter half." meaning " word for example, pressing big priority principle, to split into " sound " word be first half, and can not split into " standing " word is first half, and this can be avoided " meaning " word and " sound " word repeated code; " distinguish ", " debating " two words, part can not become word separately in its left side, splits into " suffering " for first half, remaining part be a latter half, fractionation is convenient to discern " distinguishing " like this, " debating " two word difference are avoided repeated code.

This encoding scheme rule:

1, single character is got four yards on foot by the corresponding key of two stroke combination of order of writing strokes; (2,4, the 6 even stroke) of not enough 8 strokes be blank fill bond bundle directly, and (1,3,5,7 strange stroke) last picture is got single and drawn district's corresponding keys end.

2. combinde rqdical character is split as first half, latter half.First half is less than 4 strokes, and is consistent with the single character code taking rule.First half 4 is drawn above (containing 4 draws), and first half is only got preceding two yards by the corresponding key of two stroke combination of order of writing strokes, and latter half is got two yards of residues by the corresponding key of two stroke combination of order of writing strokes equally; (the 2 even stroke) of not enough 4 strokes be blank fill bond bundle directly, and (1,3 strange stroke) last picture is got single and drawn district's corresponding keys end.

3, phrase coding rule

Preceding two yards of every word got in (1) two words;

Preceding two yards and last two words first yard of first word got in (2) three words;

(3) multi-character words is got first three word and the last character first yard.

Advantage of the present invention is; Two stroke codes are a kind of extremely simple input methods, follow people's writing style fully; Simplify most people's decoding thought process, can write and to typewrite, need not to carry on the back radical, need not meeting phonetic, and as regular as clockwork is arranged in the key position; Simply, easily learn, handy, study coding 2 minutes can easily be imported any Chinese character, and the repetition rate of coding is far below the phonetic sign indicating number, after using a period of time, stroke decomposes and reaches skill level, can reach fast input speed the radical type coded input method (as five-stroke character input method).
