Abstract

This invention relates to a kind of coding method and related miniature keyboard for western characters. The invention assigns a 3-digit number that has specific value to every western letter. The 3-digit number corresponding to a letter is the code of this letter, which is composed of three numbers, namely, 0, 1 and 2. The total of corresponding modes that correlates the three-digit code with letters of alphabet is the factorial of 26, which is 4×10²⁶. The data input keyboard that introduces this coding principle can be simplified as to a miniature keyboard that is consisted of only three input keys, which can be used as data input device for small portable electronic equipment and the like to replace traditional large keyboards. Besides, this coding method can be designed as a kind of tool for character games.

Claims

1. A coding method for western characters, characterized in that,

every letter in the western alphabet is assigned a 3-digit number that has specific value, the 3-digit number corresponding to a letter is the code of this letter, which is composed of three numbers, namely, 0, 1 and 2;

the total of corresponding modes for this 3-digit code specifically corresponds to a given letter in the alphabet, e.g., whether should (002) or (001) stand for the letter ‘

I’

, is the factorial of 26, which is 26×

25×

. . . ×

1=4×

10²⁶.

2. A coding method for western characters of claim 1, characterized in that, at least one group of the codes of the 26 letters from A to Z is as follows:

3. A games tool for western characters based on the coding method as defined in claim 1, characterized in that,

it is consisted of at least six movable standardized cubic blocks, at least three movable rectangular poles independent of each other and at least one base;

said base being for the placement of the rectangular poles, on which the three rectangular poles separated by a certain distance in respect to each other stand upright;

there being on the standardized cubic blocks a rectangular through hole, whose sectional area is slightly bigger than those of the rectangular poles, and the height of the rectangular poles at least equaling to the height of two cubic blocks;

the number(s) of the standardized cubic blocks being put through on each of the rectangular poles being the numbers of the Crypto-Grid.

4. A miniature keyboard based on the coding method as defined in claim 1, characterized in that,

it is consisted of three keys 1 and a coding base 2 on which three holes 3 being set up, keyboard 11 being fit together with the coding base 2 by keys 1 being inserted into holes 3;

each key of said keyboard 11 being designated in three states {‘

0’

, ‘

1’

, ‘

2’

}.

5. A miniature keyboard of claim 4,

wherein the structural shape of the keyboard is of a palm type.

6. A miniature keyboard of claim 4,

wherein the structural shape of the keyboard is of a flat type that can be built in small portable electronic equipments.

7. A miniature keyboard of claim 4,

wherein the structural shape of the keyboard is of a telegraph type.

8. A miniature keyboard of claim 4,

wherein the structural shape of the keyboard is of a piano type.
