Method to sequentially encode PINYIN of Chinese character with few symbols
First Claim
Patent Images
1. A method of delineating a Chinese PINYIN form with few symbols comprising steps of:
- (a) dividing elementary PINYIN symbols into coding groups included in a lookup table;
(b) associating each coding group with a coding symbol;
(c) differentiating elements within said coding group with a coding symbol or a string of coding symbols;
(d) converting the elementary symbols within said Chinese PINYIN form sequentially into said coding symbol or said string of coding symbols; and
(e) rendering said coding symbol within a string of coding symbols achieved by said converting method sequentially to a unique PINYIN element;
whereby said Chinese PINYIN form is delineated by few coding symbols of said coding symbols, and the string of said delineated coding symbols is uniquely correlated to the original Chinese PINYIN form; and
wherein the lookup table contains PINYIN symbols in either Romania form or classic Chinese form of 20 elementary initial consonants, 6 elementary vowels and 4 tones, and the elementary symbols have been divided into 10 coding-groups or coding set by means of;
each set contains one double coding consonant item, one single coding consonant item and an additional coding vowel or tone item;
each set is associated with a coding symbol or a digit;
an individual PINYIN element is coded by its coding symbol except for that;
said double coding consonant item is coded by the double coding symbol;
said additional coding vowel item is coded by its coding symbol plus a different coding symbol when said additional coding vowel appears at the initial position of a PINYIN form, whereby said Chinese PINYIN symbol in either Romania style or classic style is converted to a coding symbol or a string of coding symbols, which is uniquely correlated to its original PINYIN symbol during the sequential delineating process.

Abstract
A method of encoding Chinese character PINYIN into digital string and utilizing a key pad to input Chinese character to computer is described herein. The pronunciation of a Chinese character can be described by Romania form of 26 letters, and four tone indicators. In accordance with the present invention, a lookup table has been composed, allowing the 30 symbols to be grouped into ten sets. Each set is associated with group identification respectively. In operation, a key pad mapped with the lookup table allows individual symbol of PINYIN to be inputted directly using group identification as medium. Individual symbols are retrieved exclusively through the group identification and echoed step by step. A human-machine interface similar to an ASCII compatible keyboard has been established by the method for a small key pad compatible to phone set during the PINYIN inputting process. An inputted PINYIN is used to retrieve a Chinese character further.
