Abstract
The present invention discloses a head-end structure shape code geometrical method Chinese character coding method and a keyboard. In the method, firstly, a stroke or a stroke shape of a Chinese character is divided into a line shape, an angle shape, a frame shape (a linear angle shape) and a line fork shape which are relevant with numeric codes from 0 to 9, and then Chinese characters are arranged according to a structure and a head-tail code in a writing order and are input through a redefined standard keyboard. The keyboard comprises a standard key. The present invention is characterized in that 1-99 and 0, 00, 01-09 codes are defined on a number key and a letter key, the letter key defines a two-bit digital code, and the number key defines a one-bit digital code or the two-bit digital code. Every key respectively defines the one-bit digital code or a two-bit digital code from one to ten, and the present invention is visual. Memory and a coincident code are reduced, and the keyboard is easy to operate.
Description
The present invention relates to digital machine, Digital Data Processing Equipment in the computing technique, be a kind of with transformation of data to be processed become the input media of the form that computing machine can handle, specifically, be the device that in the manually input fragmented information project is converted into code form, for example: the keyboard that produces alphanumeric code, operand code, instruction code.
Present Chinese character coding method roughly is divided into phonetic sign indicating number, font code and phonetic-stroke code three classes.Though each has something to recommend him, have quite a few drawbacks.The phonetic sign indicating number is because repeated code is many, speed is low, and the Chinese phonetic alphabet extensively do not grasped, and practicality is bad, and using more at present is font code and phonetic-stroke code, as king's sign indicating number, Lee's sign indicating number and yard.Though these methods are practical, but it is complicated loaded down with trivial details, the code of regulation or normal root, font need remember by recitation (king's sign indicating number has the radical of more than 200 needs memory), and the difficulty of divining by means of characters, easily make mistakes, add that code length and keyboard Designing are undesirable, general individual character input will be by four keys, and code element and key position lack inherent getting in touch, regularity is not strong, therefore brings difficulty to operational applications.So-called font code, promptly encode according to the form of a stroke or a combination of strokes, carry out in the Methods for Coding for Chinese character in numerous utilization numerals, number is just represented a single or folding stroke, and as " horizontal, vertical, left, points, discount " five, it is mechanical and narrow that digital intension and extension seem, simultaneously, because this number is an input signal of artificial regulation purely, lack inherent comparability between the pen sign indicating number, so be difficult to grasp and use.
The purpose of this invention is to provide a kind of directly perceived, image, with Chinese character stroke or the form of a stroke or a combination of strokes and the direct pictograph of arabic numeral, convenient memory, minimizing repeated code, code is arranged rationally, and better regularity is easy to geometrical method begining-end structure code format Chinese character coding method and the keyboard grasping and operate.
Technical solution of the present invention is:
A kind of geometrical method begining-end structure code format Chinese character coding method, point unlike the prior art: at first the Chinese character stroke or the form of a stroke or a combination of strokes are divided into linear, dihedral, shaped as frame (line angle shape) and line fork-shaped four classes, and get up with " 0-9 " ten arabic numeral code association; Then Chinese character is carried out head and the tail by its structure and sequential write and encode and be arranged in order, utilize the general international standard keyboard that redefines to import again.
Font code method of the present invention is divided into: (1) whole pictograph.As: mouth-0, Shu-1,7-7 etc.(2) last portion pictograph.As: one-2, ten-4, fourth-5 etc.
The linear of the Chinese character stroke among the present invention or the form of a stroke or a combination of strokes drawn for straight pen, comprising: perpendicular, point, right-falling stroke are with code " 1 " expression, and horizontal drawings code " 2 " expression is cast aside with code " 3 " expression; Dihedral links to each other for folding stroke and the order of strokes observed in calligraphy and not parallel two straight pens are drawn the horn shape form of a stroke or a combination of strokes of formation, comprising: upper left dihedral is with code " 5 " expression, and right corner shape is with code " 6 " expression, and the lower-left dihedral is with code " 7 " expression; The line fork-shaped is that straight pen is drawn the crossing form of a stroke or a combination of strokes, comprising: horizontal fork is indulged and is pitched with code " 8 " expression with sign indicating number " 4 " expression; The sealing that shaped as frame (line angle shape) is connected to form at the end place for linear and dihedral or do not seal the frame form of a stroke or a combination of strokes comprises: the sealing frame is with code " 0 " expression, do not seal frame with code " 9 " expression.
Sealing frame identification code among the present invention is divided into three kinds in " little 0 ", " big 0 ", " long waist 0 ".
Chinese character among the present invention by the principle that structure and sequential write carry out the arrangement of head and the tail coding is:
(1), the Chinese character of structure about, up and down or in outer, according to stroke order choose the left or up successively, locate first sign indicating number before two yards works of the first stroke of a Chinese character of font, get first sign indicating number behind two yards works of the first stroke of a Chinese character of right or down, lining font again, get the not tail of right or down, lining font at last and make the tail sign indicating number for two yards, each initial and end sign indicating number is if deficiency is then got one yard or vacancy.
(2), contain the Chinese character that left and right sides font becomes up-down structure again, get first sign indicating number before two yards works of the first stroke of a Chinese character of first font, first sign indicating number behind two yards works of the first stroke of a Chinese character of remaining font, the not tail of remaining font is made the tail sign indicating number for two yards, each initial and end sign indicating number is if deficiency is then got one yard or vacancy.
(3), can not be divided into the Chinese character of two bodies, get four yards of the first stroke of a Chinese character according to the order of strokes observed in calligraphy and make first sign indicating number, tail is not made the tail sign indicating number for two yards, if the initial and end sign indicating number is then got one yard or vacancy not enough.
(4), except that a code word, all should divide head and the tail, have only the word of two numbers, according to stroke order respectively get a number and make first sign indicating number tail.
When the general international standard keyboard that utilization of the present invention redefines is imported, input in order " preceding first sign indicating number ", " the first sign indicating number in back ", " tail sign indicating number "; Lack one group or two groups in the above-mentioned decode, add a defeated space code after being totally lost.
A kind of keyboard according to begining-end structure geometric method method of Chinese character coding design comprises the general international standard key, and difference from prior art is: on numerical key and letter key, from top to bottom, defined 1-99 from left to right, and 0,00, the 01-09 code; Letter key is the defined double figures sign indicating number that is except that the key that is defined as " long waist 0 " and " big 0 ", and numerical key then is one digit number sign indicating number or double figures sign indicating number; Each key has defined an one digit number sign indicating number or one～ten two bit code or an one digit number sign indicating number respectively and has added one～ten double figures sign indicating number.
On the numerical key among the present invention respectively correspondence defined 1 and 10-15,2 and 20-24,3 and 30-34,4 and 40 and 41,5 and 50 and 51,6 and 60 and 61,7,8 and 80-89,9 and 92, little 0 and little by 00; Defined 16,25,35,42 and 43,52 and 53,62 and 64,70 and specific 71, little by 09, long waist 0 of 93-96, little 01-and the long waist 09 of long waist 00-on the letter key respectively first row; Defined 17 and 18 on the letter key respectively second row, 26-29,36 and 37,44-46,54-56,66 and 68, specific 71,90 and 91 and 97-99, big 0 and big 00-big by 09; The 3rd row has defined 19 on the letter key respectively, space code, 38 and 39,47-49,57-59,63 and 65 and 67 and 69,71-79.
On each digital code definition key among the present invention, indicate 1 or the several typical stroke or the form of a stroke or a combination of strokes respectively, it is Chinese character that its form of a stroke or a combination of strokes is originally penetrated, and this word is directly corresponding with this key, is regardless of head and the tail.
Advantage of the present invention is: owing to make full use of thinking in images, with Chinese character stroke or the form of a stroke or a combination of strokes and arabic numeral direct " pictograph " or " understanding ", visual pattern is understood and memory easily, almost consistent as numeral " 1 " with perpendicular (1), the beneath of " 2 " is horizontal (one), " 3 " tail is for casting aside (Pie), so 1, one, the code of Pie represents with 1,2,3 respectively.Press down (
), point (Dian) presentation direction is downward, and is similar to perpendicular (Shu), also uses " Shu " expression, in like manner, carry (
) cause with horizontal (one), also use " 2 " expression.
Horizontal fork (ten etc.) pictograph is " 4 ", and vertical fork (king etc.) pictograph is " 8 ", and upper left dihedral (亅, etc.) pictograph is " 5 ", right corner shape (
, Yin etc.) pictograph is " 6 ", lower-left dihedral (, Ya etc.) pictograph is 7, sealing shaped as frame (mouth) pictograph is " 0 ", do not seal frame (
Deng) pictograph is " 9 " etc.Thereby reduce people's rote memory difficulty.The convenient grasp and use also makes the definition key on the keyboard arrange more to become rationally simultaneously, has good regularities.Realized that real font code is same, seen that shape is as seeing sign indicating number.
Owing to adopt the Head-Til stroke Chinese code structure, not only reduced repeated code, as long as and just can import a general individual character, high input speed by triple bond.
The invention will be further described below in conjunction with chart and embodiment:

Coding cardinal rule of the present invention is as follows:
1, press the structure of word, about splitting into, two fonts up and down or in outer.Get two yards of the first stroke of a Chinese character of two fonts, get two yards in the end pen of back font, coding successively, head and the tail are not enough, can only compile one yard or vacancy.
2, many structures of font, or when several division is arranged, by following rule:
(1), with reference to radical, (referring to example 10,11,12)
(2), preceding shape is little.(referring to example 9,12,28)
Keyboard of the present invention uses cardinal rule as follows:
1, input is during Chinese character, and order has only the word of " head " or " initial and end " by the maximum triple bonds of " preceding head-back head-tail " sign indicating number, pressed a key or two keys after, add a space bar "/" (X).(referring to example 1,6,19)
2, with in-line under different begining-end structure situations, because of the code fetch difference, the key position is not necessarily identical.(referring to " very little " in the example 5,25; 16, " woman " in 17)
3, the key position is except that indicating code, also has one or several typical form of a stroke or a combination of strokes, the upper left corner be the unit number form of a stroke or a combination of strokes, the upper right corner be the double figures sign indicating number form of a stroke or a combination of strokes (referring to example 5,14).
When the individual character input done in key face font, be regardless of Head-Til stroke Chinese code, directly add " X " key by this key.So just can distinguish individual character.(example 18,19; 20,21,22,23)
The explanation of several keys position:
(1), the key position of digital " 71 " has three: " U, J, M ", " U " key only are used for " Yin ", " Chuo " form of a stroke or a combination of strokes, and " J " key only is used for " Xin " shape, and all the other are as " again ", “ " ... all use the M key.(referring to example 10,25,30)
(2), " moon ", " day " be when making the tail font, and be same only by a key, as phase=47-02-/, do not make 47-02-2.
(3), different " mouth " (frame) will be with different " 0 " sign indicating number keys.(referring to example 24,25,26,27,29) in addition because " by " " first " " Shen " three word codes all are 021, special regulation: " by " with 021; " first " is with 021; " Shen " is with 021.For example import individual character: by=0-21-/; First=0-21-/; Shen=0-21-/.When making head and the tail, as duck=0-35-52; Freely=02-53-3.Attention: 0 of second order digit sign indicating number is all made " little 0 " (referring to example 7,32)
(4), the specific form of a stroke or a combination of strokes " power " work " 35 ", " an ancient type of spoon " work " 63 "
" heart " economized a little with " Xiangxi " and is decided to be " 16 ", " 7 ".(referring to example 13,31)
Adopt two monic stern construction encoded moving images of the present invention directly perceived, in fact increased the code element information of intermediate structure, simultaneously, digital identical, arrangement regulation different as: 53741 one-tenth capable of being combined: 53-74-1,53-7-41,5-37-41 etc. can express the Chinese character of different structure, have significantly reduced repeated code.

2, a kind of begining-end structure font code geometric method computer Chinese input method is characterized in that: at first with Chinese character stroke or the form of a stroke or a combination of strokes and the direct pictograph of " 0-9 " arabic numeral, and be divided into linear, dihedral, shaped as frame and line fork-shaped; Each Chinese character is designated as maximum three groups of codes, and imports by preceding first sign indicating number, the first sign indicating number in back, the corresponding successively one～triple bond of tail sign indicating number according to its structure and sequential write:
A: 1., linearly draw for straight pen, comprising: perpendicular, point, right-falling stroke are with code " 1 " expression, and horizontal, drawings code " 2 " expression is cast aside with code " 3 " expression;
2., dihedral links to each other for folding stroke and the order of strokes observed in calligraphy and the horn shape form of a stroke or a combination of strokes of not parallel two linear strokes of formations, comprising: upper left dihedral is with code " 5 " expression, right corner shape is with code " 6 " expression, the lower-left dihedral is with code " 7 " expression;
3., the line fork-shaped is the linear stroke of crossing form of a stroke or a combination of strokes, comprising: horizontal fork is with code " 4 " expression, vertical fork is with code " 8 " expression;
4., shaped as frame is the sealing that is connected to form at the end place of linear and dihedral or do not seal the frame form of a stroke or a combination of strokes, comprising: the sealing frame is with code " 0 " expression, do not seal frame with code " 9 " expression;
5., the sealing frame identification code is divided into three kinds in " little 0 ", " big 0 " long waist " 0 ";
B: input step is: Chinese character carries out the head and the tail code fetch by structure and sequential write, and the principle that coding is arranged is:
1., the Chinese character of structure about, up and down or in outer, according to stroke order choose the preceding first sign indicating number of two yards works of the first stroke of a Chinese character of left or up, outer font successively, get first sign indicating number behind two yards works of the first stroke of a Chinese character of right or down, lining font again, get the end of right or down, lining font at last and make the tail sign indicating number for two yards, each initial and end sign indicating number is if deficiency is then got one yard or vacancy;
2., contain the Chinese character that left and right sides font becomes up-down structure again, get first sign indicating number before two yards works of the first stroke of a Chinese character of first font, first sign indicating number behind two yards works of the first stroke of a Chinese character of remaining font, the tail sign indicating number is made for two yards in the end of remaining font, each initial and end sign indicating number is if deficiency is then got one yard or vacancy;
3., can not be divided into the Chinese character of two bodies, get four yards of the first stroke of a Chinese character according to the order of strokes observed in calligraphy and make first sign indicating number, the tail sign indicating number is made for two yards in the end, if each initial and end sign indicating number is then got one yard or vacancy not enough;
4., except that a code word, all should divide head and the tail, have only the word of two numbers, according to stroke order respectively get a number and make Head-Til stroke Chinese code;
5., input " preceding first sign indicating number " in order, " the first sign indicating number in back ", " tail sign indicating number ", lack one group or two groups in the above-mentioned decode, add a defeated space code after being totally lost.
