The objective of the invention is to overcome the deficiency of prior art, and provide a kind of code element of each encode Chinese characters for computer only relevant to the stroke classification order of combination with each stroke, and with the irrelevant a kind of input method of Chinese character of the particular location of each numeral on keyboard based on numeric keypad equipment.

The present invention is divided into four words, three words, two words, four kinds of structures of monolithic word to Chinese character according to the Chinese character natural structure, Chinese-character stroke is divided into tiltedly (left-falling stroke, point, press down, carry), horizontal, vertical (folding) three types, get a two-stroke that constitutes each block of Chinese character by above stroke classification, corresponding with the key position distribution of numeric keypad, form 3 * 3 two-dimensional coordinate coding (seeing accompanying drawing); Font be divided into about single character, mostly encirclement, semi-surrounding, broad sense, about, the left, center, right, broadly upper and lower in following 9 types (wherein: the outer encirclement scopes of surrounding are for more than or equal to 3/4ths mostly, as enclose, rectify etc.; The outer encirclement scope of semi-surrounding is 1/2nd, as the Room, like this; Be left and right sides font about broad sense, wherein the left side, the right partly at least also can further split; Font about broadly being down, wherein top, following part at least also can further split), correspond respectively to digital 1-9 (seeing accompanying drawing).

Maximum code length of the present invention is 5 yards, and wherein the monolithic radical is carried out to code fetch according to the stroke sum of Chinese character, 5 yards of less thaies in stroke combination coding and font code centre with digital 0 polishing.

Concrete input method of the present invention and keyboard arrangements are:

1, four words: (first block is the first sum of, inferior pen) (second block is the first sum of, inferior pen) (the 3rd block is the first sum of, inferior pen) (the 4th block is the first sum of, inferior pen) font code;

2, three words: (first block is the first sum of, inferior pen) (second block is the first sum of, inferior pen) (the 3rd block is the first sum of, inferior pen) (first block end pen, the 3rd block end pen) font code;

3, two words: (first block is the first sum of, inferior pen) (second block is the first sum of, inferior pen) (first block is the first sum of, and second block is the first sum of) (first block end pen, second block end pen) font code;

4, monolithic word:

(1) one, two stroke words: (the first sum of, end pen) 000 font code;

(2) three, four stroke words: (the first stroke, second) (the 3rd, the end pen) 00 font code

(3) five, six-stroke word: (the first stroke, second) (the 3rd, the 4th) (the 5th, the end pen) 0 font code

(4) seven strokes and above word: (the first stroke, second) (the 3rd, the 4th) (the 5th, the 6th) (the 7th, the end pen) font code

According to the design of above input method and keyboard arrangements as can be seen, the present invention thinks ratio with similar digital encoded method for inputting, have Chinese character and split standard, simple, directly perceived, the coding method learning cycle is short, memory capacitance is little, can realize characteristics such as touch system, can be applicable to following field:
