Precise Encoding and Direct Keyboard Entry of Chinese as Extension of Pinyin

Abstract

Encoding Chinese in one(linear code)-to-one(character or word) correspondence systematically has been a century old challenge. Based on the official standards for Pinyin and writing order of characters, that all Chinese users are familiar with, this invention comprises: (1) encoding all characters and words of a predetermined set or dictionary into distinct codes in electronic system like computer; (2) retrieving character or word by decoding user's keyboard input, and then entering the corresponding character or word into the system. Denoted inside [ ], the proposed Pinyin+X coding format is [Pinyin+X]=[Pinyin]+[3-Stroke]+[Extra], where [3-Stroke] consists of three consonant letters coding for the first, second, and last stroke of the writing form of character or word, and [Extra] is system-generated consonant letter(s) to ensure the uniqueness of the entire [Pinyin+X] code. Pinyin+X keyboard entry process for Chinese can therefore be designed to be direct that every keystroke counts and none is extra.
