Description

 Method for inputting Chinese characters by using continuous pinyin on digital keyboard

 The invention relates to a method for inputting Chinese characters by smart pinyin, in particular to a method for inputting Chinese characters by pinyin using a numeric keypad, in particular to a method for inputting Chinese characters by using continuous pinyin on a numeric keypad.

Background technique

 With the development of information technology, the communication methods people use are no longer limited to voice, but need to express their feelings through text short messages or E-mail. The existing Chinese input technology of mobile phones mainly includes the Chinese Pinyin input method and the stroke input method. The Chinese Pinyin input method uses the single-word pinyin input technology, but there are obvious defects: The numeric keyboard (especially the standard mobile phone numeric keypad) mainly uses the traditional letter layout method, that is, 26 Latin letters are sequentially distributed in 2-9. On the eight numeric keys, each key is distributed by 3-4 letters. The user presses the number key corresponding to the pinyin letter of the single Chinese character, and then confirms the pinyin from the candidate pinyin combination that conforms to the Chinese Pinyin rule. Chinese characters are selected among the candidate words corresponding to the confirmed pinyin. Because there are many homophones in Chinese, and there are more words with pinyin in the absence of tone, you usually need to press the navigation button many times to select the word you want to input, and then repeat the above steps to enter the next Chinese character. This single-word pinyin input method is slow and cannot perform smart pinyin input of phrases or whole sentences. There is no problem with the stroke input, but the defect is that the stroke input requires a "Chinese character → stroke → number" thinking conversion process, and the stroke input is only applicable to "see lose", not to "hear lose" and "think" Loss,,, that is, when you think of the pronunciation of a word but forget the wording, the input speed will be greatly reduced.

For reference, the patent application number "02102200.3" is entitled "Improved numeric keypad and Chinese character pinyin input method using the keyboard", and the patent application number is "03119525.3". The Chinese patent with the patent name "Digital Keyboard Pinyin Input Method" reduces the input bit rate by changing the position of the spelled letters on the keyboard number keys, but the result is that the standard mobile phone number keyboard pinyin is already used. It is inconvenient for users of letter keys, and the input speed and accuracy of input are greatly affected.
