Abstract

The invention discloses a digital consonant-vowel double-phonetic alphabet input method. The invention defines the different double hits of the keys with different key values; according to the inherent group structures and inter-group arrangement relations of the consonants and vowels in the Chinese Phonetic Alphabet, the invention adopts an integrated layout method that the consonants and vowels are separated and grouped respectively, wherein, each group is a key and each key has a plurality of bits, and the values are defined according to the bits, so that the definitions of the group of <keys> and the value of <bits> have unified rules and clear corresponding relationships. The invention aims to achieve the improvements on easy key-bit memorization and rich code source, so that the digital double-phonetic alphabet operation on hand-held devices can reach the technical indicators equivalent to the double-phonetic alphabet operation of the QWERTY keyboard.

Description

Digital initial and final double-spelling input method

Affiliated technical field:

The present invention is a kind of according to the method for the Chinese phonetic alphabet to digital code information terminal input Chinese character.

Background technology:

The spelling input method that uses on the handheld digital device such as present mobile phone mostly is the spelling mode greatly, and phonetic alphabet will be keyed in singly.Stroke is more, and letters case do not meet the inherent law of the Chinese phonetic alphabet according to English series arrangement, and majority do not remember the key position, and input speed is extremely difficult satisfactory.

Though there is the numbers and double spelling syllables scheme to emerge, mostly be the empty talk of assuming as a matter of course, both do not solved the difficult problem of key position memory, do not solve the sign indicating number limited restriction in source to practicality yet.All are resulting Two bors d's oeuveres on trivial 10 keys, all be removing to tackle thousands of Chinese-character pronunciation with 100 theoretical sign indicating number sources, and Word selection method thereafter is also very forced, and such scheme nobody is ready to put into practice.

Summary of the invention:

Digital initial and final double-spelling input method---be called for short Phonological input method, Chinese phonetic alphabet consonant, vowel are complied with himself natural inner link, adopt sound to separate, divide into groups respectively, same on the same group key, a key multidigit, the way of cis-position definite value, comp comprehensive layout realize easy note in key position and yard source abundant two improvement greatly.Concrete grammar is:

One, initial consonant grouping

With five groups is example: b group---b, p, m, f (", " separate expression and will define respectively, down with)

D group---d, t, n, l

G group---g-j, k-q, h-x, w ("-" connects expression and define consistent, down together)

Zh group---zh, ch, sh, r

Z group---z, c, s, y

Two, simple or compound vowel of a Chinese syllable grouping

With full row group is example:

(1) first vowel method of grouping

A group: a, ao-ai-an, ang

O group: o, ou, ong

E group: e, er-ei-en, eng

I group: i, ia-ie-iu-in, iao-ian-ing, iang-iong

U group: u, ui-ua-un-uo, uai-uan, uang

ü group: ü, ü e-ü n, ü an

(2) pivot sound method of grouping

A group: a, ia-ua-ao-an-ai, uai-uan-iao-ian-ang, iang-uang

O group: o, ou-uo, ong, iong

E group: e, er-ei-en-ie-ü e, eng

I group: i, ui-in, ing

U group: u-ü, iu-un

First vowel grouping and pivot cent group in the simple or compound vowel of a Chinese syllable grouping can be chosen one wantonly for the input mode of determining.The initial consonant grouping then can be general.

Three, key position corresponding relation

To initial consonant, each group of simple or compound vowel of a Chinese syllable, arrange button by the principle of one group of one key.The different value of different strokes definition to each button: in principle, the value of setting consonant key is the number of times of continuous keystroke be consistent with the group internal sort (example: hit the b key and represent b once, hit twice expressions of b key p, hit three times expressions of b key m, hit four times expressions of b key f); The value of setting final key is that stroke is character length consistent (example: hit the e key and represent e once, hit e key two expressions ei or en or er, hit three times expressions of e key eng) with the simple or compound vowel of a Chinese syllable number of characters.

Can do a small amount of the adjustment in conjunction with the balanced situation of Chinese character syllable when more than being grouped in actual keys arrangement, just optimize.For example: ü group can with u group or o combination also, but the result of maintenance data storehouse technical Analysis shows, with the o combination and conflict minimum and complementary the strongest; The ian simple or compound vowel of a Chinese syllable can move to the bottom of the less o simple or compound vowel of a Chinese syllable group of syllable separately, and with crowding of the 3rd layer of the few i simple or compound vowel of a Chinese syllable of letter, balanced code source distribution improves global index; For the few stroke of letter, bring into play the advantage that consonant key exempted to hit in 0 simple or compound vowel of a Chinese syllable, the situation reduction that adds, changes w and y in the Scheme for the Chinese Phonetic Alphabet is handled.

The neighbouring relations of each group between button are arranged in order according to Scheme for the Chinese Phonetic Alphabet binding operation is convenient equally.Be initial group head initial consonant pronunciation series arrangement, the simple or compound vowel of a Chinese syllable group is arranged by the opening degree of first vowel or pivot sound.

Four, input method

During input, according to the intrinsic rule sound two key Two bors d's oeuveres input of the Chinese phonetic alphabet, the only key input of 0 initial consonant word.Can carry out word selection after the syllable end of input of determining or word is decided in other identification, also can use intelligent association to import continuously.Different is with the input of Two bors d's oeuveres on the qwerty keyboard, and the key assignments major part here is by the double hit of button is got.So-called " two keys " refers to the key number that relates to, and promptly the keystroke number is two keys, but stroke is usually greater than 2.But this does not hinder the performance of this input method, because Dao Xiang double hit is hit than the choosing between the different keys consciously, both convenience and efficient differ widely.Even if do not talk merger with the key double hit, total but its stroke does not surpass spelling yet, simplified keystroke on ground really really.And this input method will be as the division of another invention, finishes the frequent batch efficient typing of handheld device basic data in moving jointly.

Five, the technical matters of Xie Jueing

The technical matters that the present invention solves comprises:

(1), solved the memory difficult problem of sound mother with the key position.The Two bors d's oeuveres input must define 23 initial consonant key assignments, 35 simple or compound vowel of a Chinese syllable key assignments.Although original various scheme has been taked many creative " tactical deployments of troops ", but because these 48 elements will repeat on interior button inevitably in a large number at 10, the aborative peculiar scheme of inventor allows people's one something worth seeing just big often, and its result is a refusal.This input method makes full use of the foundation of people's figure viewed from behind knowledge as grouping cloth key, will become the understanding to group to the memory of element, will become the understanding of button being controlled rule to the memory of group.Meet people's thinking and operating habit, simplified memory greatly.

(2), solved the difficult problem of sign indicating number source deficiency.GB2312 has 6763 Chinese characters, and 7288 pronunciations relate to 408 and become the word syllable.The definable element of original digital Two bors d's oeuveres is 10, and theoretical maximum sign indicating number source is 100, can't differentiate more than 400 syllable, can't carry more than 7000 Chinese character.Adopt the key assignments define method of this law, the definable element can reach 40 even more, suddenly sign indicating number source sum is brought up to 420, and actual effective code source reaches 357, and the different pronunciations of the Chinese character of can effectively emanating are near the Two bors d's oeuveres index on the qwerty keyboard.Greatly enriched the sign indicating number source.

More than the two big technique effects that produce that improve, at first be to make that the digital Two bors d's oeuveres of non-qwerty keyboard mode has had reliable practicality on the handheld device.This law is on average held for every yard and cut out number of words than original digital Two bors d's oeuveres scheme minimizing 75%, and is approaching with qwerty keyboard Two bors d's oeuveres index; And the memory of key place value is required because of being to implement totally according to the phonetic plan in the background knowledge, obviously want much simple than the memory of the strong value defined of qwerty keyboard Two bors d's oeuveres.So digital initial and final double-spelling input method is practical.Its direct effect is that hand-held digital equipment needn't can be realized the Two bors d's oeuveres input by the adapted qwerty keyboard fully, and its operation is obviously simple and efficient than qwerty keyboard.The more important thing is that the input speed suitable with the keyboard Two bors d's oeuveres that this law can reach is that current any other handheld device input method (stroke, hand-written, spelling etc.) is incomparable on handheld device.Key point one of the present invention is to be to have utilized with button to do not exist when Two bors d's oeuveres is imported with even defeated this fact of situation of value, thereby different double hits is used for different key assignments definition.The 2nd, hierarchical relationship and redundancy and vacancy in the intrinsic group framework that has utilized sound mother in the Scheme for the Chinese Phonetic Alphabet and the group make the definition of group and the value of " position " of " key " that unified rule and corresponding relation clearly arranged.
