【摘要】 针对汉字在键盘输入中的编码方式普遍存在汉字编码规则的难易与其输入效率相矛盾的问题,提出了一种新的汉字编码:U码.U码基于音形模式(音,采用汉字声母的首字母;形,选取汉字常用的50个偏旁或部件为码元),根据偏旁和部件的读音或形似等原则映射到26个英文字母键元上,具有偏旁部件与键位对照规律性强的特点.U码在降低重码率的前提下,同码、重码汉字最多6个,弥补了目前手机键盘操作中,同码汉字多,影响录入速度的不足,具有了向手机移植的硬性指标.U码输入法最大码长为4,平均码长为1.598,键选率为11.021%.更多还原

【Abstract】 Considering the fact that the rule of coding in Chinese characters key board input methods coexists with various Chinese coding methods in keyboard inputting and the efficiency of inputting, we put forward another new kind method of Chinese coding termed U code. The U code is based on sound form mode ( sound :the sound in sound form mode represents the first letter in pingyin of Chinese characters; and the form is selected from the fifty common unit parts or components which form the Chinese characters, which are the unit codes),projecting 26 English letters of those on the keyboard according to the rule of pronunciation of the parts or the components and the rule of similarity among the parts of Chinese characters, they poses the characteristics of regulations between the 26 English letters of the input key board units and the parts and components of Chinese characters. And the U code has reduced the number of code repeating and reappearing within 6 under the condition of decreasing the premise of the code repeating, which has made up the disadvantages of low speed of current operation of cell phone because of the high possibilities in code repeating. So the U code posses a obvious convenience in transplanting to cell phone. The longest code in U code input method is 4, and the average length of the codes is 1.598, the rate of key choosing is 11.021%.更多还原
