Abstract

The present invention discloses a two stroke input method which relates to a Chinese character code input system. The two stroke input method is an extremely simple input method which completely conforms to people's writing habits, and people's decoding thinking processes are best simplified by the present invention; people who can write can use the two stroke input method for typing, word roots do no have to be memorized, and people do no have master the Pinyin; the positions of keys are arrayed in the extremely regular manner; the simple two stroke input method can be easily learnt and conveniently used, and any Chinese character can be easily input after coding is learnt for only two minutes; the rate of coincident codes is far less than the rate of coincident codes of Pinyin codes. When the skilled degree is reached in stroke decomposition after the two stroke input method is used for a period of time, the input speed of word root type code input methods (such as, the five-stroke input method) can be achieved.

Description

Two stroke draw input method

Technical field

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

Background technology

As follows for my understanding of present technique domain background technology: 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 to 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, has prolonged the thinking deterministic process.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 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 a kind of pair of stroke of two singles picture compositions, and two stroke classes are because a key is imported two strokes of Chinese character, and the quantity of information that comprises is drawn greatly than single, so keeping under the simple characteristic of coding rule, encode code length, the repetition rate of coding all reduce significantly.With this coding method more approaching be Chinese character coding method of document number CN1184280A Chinese character and keyboard thereof, it is split as 1 to 4 branch word with each Chinese character, gets each successively and divides preceding two strokes of word to encode; Stipulated 11 radical key positions again, had radicals by which characters are arranged in traditional Chinese dictionaries preferentially to get radicals by which characters are arranged in traditional Chinese dictionaries, but appeared at that single is drawn the back or be not to be positioned at Chinese character to recover code fetch according to stroke order when anterior again.At first, tearing open by the multipotency of combinde rqdical character of this scheme is 4 branch words, gets each successively and divides preceding two strokes of word to encode; The stroke jumping characteristic is big like this, lacks continuity, does not meet people's normal order of writing strokes, has prolonged decode time, has influenced decoding speed; And influence the standardization of people (particularly students in middle and primary schools) writing Chinese characters; Secondly,, when being split as 4 branch words, a combinde rqdical character split by this scheme through 3 times; One of compare the situation that a word only is split as 2 parts, many 2 split processes have increased decoding thought process like this, have influenced decoding speed; Once more, this scheme has been stipulated 11 radical key positions, the decode key process that it makes the importer is changed into " whole word → judgements 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) → judge whether radicals by which characters are arranged in traditional Chinese dictionaries are positioned at the Chinese character front portion or whether the radicals by which characters are arranged in traditional Chinese dictionaries front has single picture (if any just not adopting radicals by which characters are arranged in traditional Chinese dictionaries) → decomposition stroke → button " by " whole word → decompositions stroke → button ", prolonged decoding thinking deterministic process, the thought process that causes decoding is complicated, has influenced decoding speed; And must remember key position, 11 radicals by which characters are arranged in traditional Chinese dictionaries places, increase memory capacitance.

Summary of the invention

The objective of the invention is to design a kind of extremely simple computer Chinese character 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.

Technical scheme of the present invention is as follows: 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: one | 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), ( Pie). ( Dian)/( ) single is drawn district: Z () X (Shu) C (Pie) V (Dian) B (), and (above-mentioned four the most frequently used key positions are all in fingering under the dexterousst forefinger control, each district from left to right all is horizontal, perpendicular, cast aside, the point, the folding arrangement) this encoding scheme single character does not split, combinde rqdical character is split as two parts by its font structure, up and down, about, about structure is write by it and successively is split as first half, latter half; 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 " space 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; The single character of not enough 8 strokes, its stroke number are even stroke, and direct blank fill bond bundle, its stroke number are strange stroke, and last picture is got single and drawn district's corresponding keys and finish; 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; 4 pictures are arranged first half or more than 4 pictures, 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; Be less than the situation of 4 strokes for latter half, its stroke is even stroke, and direct blank fill bond bundle, its stroke number are strange stroke, and last picture is got single and drawn district's corresponding keys and finish; 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.

The present invention and background technology comparison usefulness are: two stroke draw input method is a kind of extremely simple computer Chinese input method, follows 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).
