ENGLISH LETTER CODING METHOD AND A SMALL KEYPAD

摘要

The present invention relates to a kind of English letter coding method and a small keypad. The present invention assigns three figures having a determinate value, which represents the code of the letter to each English letter. The code is composed of three numbers : 0, 1, 2. The total number of the manners in which the three-bit code corresponds to the every letter in the alphabet is the factorial of 26: 4X10<26>. By using this method, the conventional keypad for inputting data can be simplified to a small keypad composed of three input keys. This small keypad can replaces the conventional keypad for using in a small mobile electronic device to input data. In addition, a word game tool can be designed by using this coding method.
