“正易全”是一个以“正”、“易”和“全”为基本指导思想的笔组型汉字编码输入法。在“正”方面,采用国际标准汉字集ISO10646 CJK, 并以《GB13000.1字符集汉字字序(笔画序)规范》和《信息处理用GB13000.1字符集汉字部件规范》指导编码;在“易”方面,以单双笔笔组和十来个常用部件为码元,按笔顺和音托等简单原则映射到26个英文字母建元上,从而避免了传统的繁复字根-键元对应表;在“全”方面,支持CJK中的所有20902字符,包括简体字、繁体字、日韩字和偏旁部首等,而且可以在不改变编码方案的前提下进一步扩充字集。正易全的单字最大码长为5个字母,平均码长4.315,键选率16.4%。该输入法的笔组-键元设计和取码模式是在对整个CJK字集作了全字编码以后多次试验、统计和优化后确定下来的。

In Chinese character input , the form-based coding method is an indispensable complement to the Pinyin-based method. The former is preferable in the cases where high-speed input is needed , where a large character set is required , where words of single characters or words missing in normal dictionaries are abundant , and where unfamiliar or rarely-used characters are more frequently used. The present paper introduces ZYQ , a stroke-group-based Chinese character input method whose development has been kept under the guidance of being Correct (in respect to the norms of language education and language application) , Easy (in respect to user friendliness and convenience) and Complete (in respect to the Chinese character set available) . ZYQ has a key-selection rate of 16.4% , while the maximum and average code lengths are 5 and 4.315 respectively.
