Description

" preceding four ends one " encode method for entering Chinese characters and numeric keypad thereof

Technical field

The invention belongs to the numerical key character coding input technology.

Background technology

1,1985, the inventor proposed a kind of easy stroke system input method i.e. " 5-stroke input method " in the 6th of claims of 1000837.2 Chinese patents, use " Shu a Pie

Second " five kinds of singles draw, and correspondence is arranged in 1,2,3,4,5 on totally 5 numerical keys, and by " preceding four ends one " code fetch, people that can writing of Chinese characters just can learn in 3 minutes, and this kind method was called as " 5-stroke input method " afterwards or was called " king's sign indicating number five font codes " input method;

This method is easy to learn, but the repeated code word is many especially, and lid has only because of space encoder ${\mathrm{\Ω}}_1=\underset{1}{\overset{5}{\mathrm{\Σ}}}{5}^i=3905,$ For example, the other word of " fish " word has more than 100, and only " fish " word side has just accounted for 4 sign indicating numbers, and last sign indicating number has only 5 possibilities, and separating capacity is just very limited.

2, I obtain No. 00100002.0 patent of invention patent mandate again after application in 2000, be intended to increase a code element " mouth ", promptly increase a key position and use 6 keys altogether, and the code fetch method is improved to " stem---surplus portion " code fetch method, " stem is got 2 yards end to end; before surplus 3 add last ", avoided the problem that a radical (as fish, deer) takies a plurality of codings, make repeated code greatly discrete; And because code length becomes 6, space encoder is ${\mathrm{\Ω}}_2=\underset{1}{\overset{6}{\mathrm{\Σ}}}{6}^i=55986,$ Compare Ω ₁Greatly increase, thus become the key position less, practical, practicability technological invention that repeated code is few.

3, I am to use 9 numerical keys to realize a technological invention of digitizing font code input by " stem-surplus portion " code fetch in No. 00103505.3 patent of application in 2000 and acquisition invention patent mandate; Because used 9 keys, though code length is 6 still, space encoder greatly increases: ${\mathrm{\Ω}}_3=\underset{1}{\overset{9}{\mathrm{\Σ}}}{9}^i=597870,$ Obviously, this is one increases a small amount of code element (as king, soil, the heart, Rui ... ten, day), the new technological invention that input efficiency just can greatly improve.

4, I am to use the digitizing font code input technology invention of 6 numerical keys by " preceding four ends one " code fetch again in No. 03150281.4 patent of application in 2003 and acquisition invention patent mandate; Because used " Shu a Pie

The second mouth " 6 keys, code length is 5, space encoder is: ${\mathrm{\Ω}}_4=\underset{1}{\overset{5}{\mathrm{\Σ}}}{6}^i=9330,$ This is a kind of increase a small amount of code element, easy to learn, new technological invention that input efficiency increases, and its technological core is from beyond example and practical under the situation of 6 numerical keys, according to " preceding four ends one " code fetch, thereby has obtained mandate.

Obviously, 6 keys of this invention, 7 of no use, 8,9 or 10 keys of its space encoder are big, such as, when still using " preceding four ends one " code fetch method, when the key position was increased to 9, its space encoder just was ${\mathrm{\Ω}}_5=\underset{1}{\overset{5}{\mathrm{\Σ}}}{9}^i=66429,$ The space encoder Ω at " preceding four ends one " during than 6 keys ₄=9330 greatly increase.As seen, be to adopt " preceding four ends one " code fetch equally, when 7,8,9 of employings or 10 key encodes inputs, its repetition rate of coding will be lower, thereby with 7～10 keys by " preceding four ends one " code fetch input, be a kind of technical progress that outstanding practicality characteristics are arranged.

Though 5 press " stem-surplus portion " code fetch with 9 keys good coding uniqueness is arranged, not easy to learn after all by " preceding four ends one ", well imagine.

6, on 7～10 numerical keys, by " preceding four arts one " code fetch input, be on the Chinese character entering technique research history, the utmost point has a creation of practicality again beyond example.

Summary of the invention

Content of the present invention is on 7 or 8 or 9 or 10 numerical keys, the single that Chinese character respectively is set is drawn and complex stroke code unit, code element on each key position can be king's sign indicating number 9 key Chinese character input methods (patent No.s: the 00103505.3) code element on the numerical key, it also can be a cover code element that increases and decreases to some extent on this basis even design in addition, arrange in addition, according to " preceding four ends one " code fetch method is the technology of encode Chinese characters for computer input, becomes the popular Chinese character entering technique of the practicality characteristics that have novelty, creativeness and give prominence to that just can learn to import in 5 minutes.

As described in above-mentioned background technology, " preceding four ends one of five strokes " input method, no doubt eager to learn, but repeated code is too many;

" preceding four ends one of 6 keys " easily learn and repeated code few, but fail to bring into play the function of whole numerical keys;

9 keys " stem-surplus portion " code fetch, though because of bond number increases, thereby space encoder enlarges repeated code seldom, even can reach the level of the Five-stroke Method, but require during disassembled coding fit Chinese character is divided into " stem-surplus portion " two parts by structure, obviously big than the difficulty of getting " preceding four ends one " by sequential write.

Outstanding practicality characteristics of the present invention are, no matter arrange what strokes or parts on 7,8,9 or 10 numerical keys, the method of its code fetch is to be unit with the code element on the numerical key, according to " preceding four ends one " code fetch, promptly only get its first, second, third, fourth and the input of the last coding, easy to learn, convenient and practical, as long as the meeting writing of Chinese characters just can be learned to import simplified or unsimplified Hanzi, and also can import for unacquainted Chinese character in 3-5 minute in the same old way.

When the Chinese Character Set that adopts is bigger, when adopting 27533 Chinese characters of large character set GB18030 word collection, after " preceding four ends one " input, repeated code can increase to some extent, but as long as retrieval software designs to such an extent that can allow everyday character come the foremost of presenting bank, be of little use word and rare characters comes the back, actual efficiency when " repeated code is many " very do not influence input, but it is more much higher than the efficient of phonetic input, this is because phonetic has only more than 400 " sign indicating number ", and under the situation of 9 keys, " preceding four ends one " then have ${\mathrm{\Ω}}_5=\underset{1}{\overset{5}{\mathrm{\Σ}}}{9}^i=66429$ Individual " sign indicating number " is 166 times of phonetic efficient coding! Be the word code of as much in this space encoder, repeated code is wanted much less than phonetic certainly.

In addition, though in the former invention of inventor, " preceding four ends one " code input method and numeric keypad design application thereof during with 6 key inputs also obtained the patent (patent No.: 03150281.4), but import for numerical key, the key position is few more, code capacity is more little, and 6 keys do not have the code capacity of 7,8,9 or 10 keys big certainly.So, reduce repeated code in order to make full use of numerical key, improve input efficiency, under the situation that is " preceding four ends one " code fetch equally, increase the key position and be not only a kind of creation, also be very necessary.

On 7,8,9 or 10 numerical keys with " preceding four ends one " code fetch, numerical key on can the flexible adaptation different product, the amount doesn't matter, can be fit to different crowds, be the code fetch method and the keyboard Designing of the science practicality created of inventor, equal beyond example at home and abroad.

The input method and the keyboard thereof of this 7 keys, 8 keys, 9 keys or 10 keys of the invention " preceding four ends one " coding, stroke, parts on its 7,8,9 or 10 numerical keys can be king's sign indicating number 9 keys (patent No.s: key position parts 00103505.3), also can choose in addition, the in addition stroke or the parts of layout, these strokes or parts should compliant, what are not limit, it is few more good more that yes, and too many being difficult for remembered, and inconvenience is used.

Under the visual field of the present invention, simplified Hanzi and unsimplified Hanzi there is no essential distinction, are nothing but that stroke is different with the code element formation, can import by " preceding four ends one " code fetch in the same old way.So the present invention can handle simplified Hanzi, also can handle unsimplified Hanzi.
