Chinese character handwriting recognition system

Abstract

A handwritten Chinese character input method and system is provided to allow users to enter Chinese characters to a data processor by adding less than three strokes and one selection movement such as mouse clicking or stylus or finger tapping. The system is interactive, predictive, and intuitive to use. By adding one or two strokes which are used to start writing a Chinese character, or in some case even no strokes are needed, users can find a desired character from a list of characters. The list is context sensitive. It varies depending on the prior character entered. Compared to other existing systems, this system can save users considerable time and efforts to entering handwritten characters.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application is a continuation of U.S. patent application Ser. No. 10 / 205,950, filed Jul. 25, 2002.BACKGROUND OF THE INVENTION [0002] 1. Technical Field [0003] This invention relates generally to text input technology. More particularly, the invention relates to a method and system that allows users to input handwritten Chinese characters to a data processor by entering the first few strokes required to write a character, so that users can perform characters input tasks in a fast, predictive way. [0004] 2. Description of the Prior Art [0005] Around the globe, over 1.2 billion people speak Chinese. This includes the People's Republic of China, Taiwan, Singapore, and a large community of overseas Chinese in Asia and North America. Chinese character strokes and symbols are so different and so complicated that they can be sorted and grouped in a wide variety of ways. One can analytically sort out as many as 35-40 strokes of 4-10 symbols ...

Benefits of technology

[0011] A handwritten Chinese character input method and system is provided to allow users to enter Chinese characters to a data processor by drawing just the first few strokes and one selection movement such as mouse clicking or stylus or finger tapping. The system is interactive, predictive, and intuitive to use. By adding one or two strokes which are used to start writing a Chinese character, users can find a desired character from a list of characters. The list is context sensitive, so in some cases no strokes are needed. It varies depending on the prior character entered. The system puts the handwritten-stroke-to-category mapping on top of the stroke category matching technology, including an optional “Match any stroke category” key or gesture. Compared to other existing systems, this system can save users considerable time and efforts to entering handwritten characters.
