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 games tool for western alphabet comprising at least six movable standardized cubic blocks, at least three movable rectangular poles independent of each other and at least one base;

the three rectangular poles being placed on the base and separated by a certain distance with respect to each other;

a rectangular through hole being provided on the standardized cubic blocks, wherein sectional area of the through hole is slightly larger than those of the rectangular poles, and the height of the rectangular poles being at least equal 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,

whereby 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; and

the total of corresponding modes for this 3-digit code specifically corresponds to a given letter in the alphabet is the factorial of 26, which is 26×
