Abstract: According to the general shortcomings of the Chinese character input method in the market, a new numerical coding method based on Pinyin and Strokes for inputting Chinese characters is presented, which encodes Chinese characters with the first Pinyin, final sound and Chinese characters of the basic stroke and a few high frequency components, and improves the numerical coding method based on Strokes and the numerical coding method based on Pinyin and Strokes. It has not only the low coincident code rate and efficient characteristics of Stroke input method, but also suits the Pinyin input method users’ inputting habit, and can meet the needs of various user groups. This paper discusses the encoding rules of this numerical coding input method, makes a detail statistics for key distribution of each code and low coincident code rate, and deeply analies and demonstrates the merit of low coincident code rate. And it briefly introduces the implementation about this input method under the Android platform.
