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.
