Abstract

A Chinese-character input method with small keypad features that the phonetic letters of Chinese character is input by pressing two keys and the pronunciation-shape code of Chinese character is input by pressing three keys. Its advantages include fuzzy sound function, numeral key input and less keystrokes (4 for 84% of Chinese characters).

Description

A kind of keypad input method of Chinese character and keyboard thereof

The present invention relates to a Technology of Chinese Information Processing.

Along with the development of information age, mobile phone, pager, information household appliances, e-dictionary are universal day by day, and associated Chinese information input also more and more is subjected to people's attention.Wherein the keypad of Chinese character input (9 to 12 keys) still exists the not high problem of input efficiency, as the phonetic transcriptions of Chinese characters in mobile phone input and stroke input need button repeatedly, the inconvenience of screen word selection, and pronunciation, stroke sequential write influence very big to above-mentioned Chinese character input.

The present invention is for solving the high and not inconvenient problem of keypad Chinese character input efficiency, provides a kind of and has the fuzzy sound in south, button is few and word selection keypad Chinese character input method easily.

This input method is divided into eight groups with the Chinese phonetic alphabet, main again save u, i, g letter according to simple or compound vowel of a Chinese syllable after last simple or compound vowel of a Chinese syllable characteristic letter simple or compound vowel of a Chinese syllable is divided into nine groups, corresponding to following table:

Table 1

Wherein the ü in the simple or compound vowel of a Chinese syllable replaces with u: simple or compound vowel of a Chinese syllable iu, ui are the abbreviations of iou, uei; " i " in the simple or compound vowel of a Chinese syllable " in, ing " do not save, and its simple or compound vowel of a Chinese syllable characteristic letter is " in "; The simple or compound vowel of a Chinese syllable characteristic letter " ^*An " in " * " expression " u " or " i ".

The order of Chinese phonetic alphabet can change, and can exchange between every group of Chinese phonetic alphabet; 1, simple or compound vowel of a Chinese syllable characteristic letter and the simple or compound vowel of a Chinese syllable group in 5,7,9 groups can be exchanged, for example 5 groups can corresponding Chinese phonetic alphabet " lmn " and the simple or compound vowel of a Chinese syllable characteristic letter " ^*An " and simple or compound vowel of a Chinese syllable group " uan, ian, uang, iang ".

With respectively corresponding nine the different keys of group number, the phonetic of Chinese character all uses two key tables to show; For the Chinese character that initial consonant is arranged, the h among initial consonant zh, sh, the ch is saved, initial consonant shows that with a key table at Chinese phonetic alphabet place simple or compound vowel of a Chinese syllable shows with a key table at simple or compound vowel of a Chinese syllable characteristic letter place; For the zero initial Chinese character, preceding two letters of its phonetic are shown with a key table respectively wherein the phonetic Chinese character that has only a letter is with two identical letter representations.

On the basis of above-mentioned phonetic transcriptions of Chinese characters two keys input, increase the key at a Chinese character initial type stroke place again, promptly Chinese character can be imported with triple bond.

The beginning stroke of Chinese character is divided into five kinds of basic strokes, i.e. horizontal, vertical, left, points, discount, the structure with Chinese character is divided into two kinds again, i.e. left and right sides structure and non-left and right sides structure; Then radical " Rui Rolling " is extracted from basic stroke, the formation initial type stroke that again three kinds of basic strokes (horizontal stroke, left-falling stroke, point) and two kinds of structures combined below is nine kinds of initial type strokes:

Table 2

Wherein first group " Rui Rolling " has precedence over other group.

Embodiment 1

With the Chinese phonetic alphabet of above-mentioned Chinese character and simple or compound vowel of a Chinese syllable characteristic letter corresponding on nine numerical keys, as shown in Figure 1.The input of " doing " is 45, and the input of " steel " is 45, and the input of " only " is 94, and the input of " youngster " is 37, and the input of " holding high " is 26, and the input of " " is 22.

Screen display such as Fig. 3, the left side of screen is the initial of input digit hurdle and candidate Chinese character phonetic, selects to fail the initial of Chinese character by specific options button; The right of screen is a candidate Chinese character.

For example, import " doing " word, input 45 earlier, as Fig. 3, the phonetic of the candidate Chinese character on " g " expression the right of screen left side band shade starts with " g ", the arrangement of the right Chinese character and the arrangement of numerical key are corresponding, can select " doing " word as input number keyboard " 2 ", can select " steel " word as input number keyboard " 6 ".If select letter " h " by specific options button, what then the right showed is that initial consonant is that " h " and simple or compound vowel of a Chinese syllable characteristic letter are the Chinese characters of " an ", as shown in Figure 4.

Embodiment 2

As above-mentioned embodiment 1, can replace Chinese character phonetic initial letters to screen Chinese character with the spelling of Chinese character, as shown in Figure 5, the phonetic of the candidate Chinese character on " gan " of screen left side band shade expression the right is " gan ".If select phonetic " han " by specific options button, what then the right showed is that phonetic is the Chinese character of " han ", as shown in Figure 6.For example, during input " sweat " word, phonetic " han " is selected in input 45 more earlier, imports 3 then and can select " sweat " word.

Embodiment 3

On the basis of embodiment 1 phonetic two keys input, increase the initial type stroke input again, promptly Chinese character is imported with triple bond.The characteristic symbol of initial type stroke is arranged as shown in Figure 2 numeric keypad, the non-left and right sides of middle row's key " 4,5,6 " expression structure, under arrange key " 7,8,9 " expression left and right sides structure and corresponding with middle row's key, under arrange key and saved the initial type stroke characteristic symbol, 7 key tables show to bypass head and to be the Chinese character of left and right sides structure, 8 key tables show with horizontal beginning and are the Chinese character of left and right sides structure that 9 key tables show with a beginning and are the Chinese character of left and right sides structure.

For example, the input in " sea " is 421, and the input of " greatly " is 325, and the input of " beating " is 321, and the input of " Da " is 328.

As shown in Figure 7, during input " thick stick ", input 458 earlier, screen the right show candidate Chinese character is imported 2 again and can be selected " thick stick " word.

Discussion of results

The spelling mean code length of Chinese character is 3.1, and the phonetic code length of this input method is 2, and code length has reduced 40% than spelling; And, can carry out word selection by numerical key again because the code length unanimity promptly can be used the numerical key input Pinyin.The spelling input of numeric keypad can't be used number keyboard selecting character because code length is inconsistent.This input method is because the enough number keyboard selecting characters of energy make word selection efficient and input efficiency improve greatly.

The input efficiency of sound shape triple bond input greatly raising keypad of this input method, if show at most that with every screen 9 Chinese characters calculate, there is 84% Chinese character directly to be presented on the screen later in the first-level Chinese characters at the input triple bond, and then select the Chinese character that will import by numeric keypad, thereby the first-level Chinese characters 84% or more is imported can realizing in quadruple linkage on the keypad.

Above-mentioned input method thereby has possessed southern fuzzy sound function owing to saved cerebral and the back nasal sound.

The initial consonant of this input method phonetic part and simple or compound vowel of a Chinese syllable can replace with the corresponding Chinese character Chinese phonetic script, thereby also are applicable to area such as Taiwan.
