新音形编码汉字输入法设计

摘要

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.%针对当前汉字输入法普遍存在的不足，提出了一种新音形编码汉字输入法，即利用汉字的首拼音、韵母及组成汉字的基本笔画和少数高频部件来对汉字编码，是对以前笔画和音形编码汉字输入法的改进。它既有笔画输入法低重码率、输入高效的特点，又切合广大拼音输入法用户的输入习惯，能够很好地满足多种用户群的需求。阐述了这种编码输入法对汉字的编码规则，对各编码的按键分布及重码率进行详实的统计，深入分析论证了其重码率低的优点，简要介绍了这种输入法在Android平台下的实现。
