Description

The short-cut method of Chinese handwriting input and retrieval

The present invention relates to the short-cut method of a kind of Chinese handwriting input and retrieval.

Present existing Chinese handwriting input product generally all adopts the technology of whole word identification, thereby all requires whole wordbook to write to the user.Thereby cause the amount of writing big, input speed is slow; Be easy to generate the mistake in the identification; For writing not full word or the Chinese character that can not write or word, can't import and retrieve, for realizing input in Chinese and retrieval, be difficult to accomplish practicability with Genius mouse.

The short-cut method that the purpose of this invention is to provide a kind of Chinese-character writing only needs any one parts of writing Chinese characters, and can omit the arbitrary portion Chinese character of word, just can realize Chinese handwriting input and retrieval.Thereby shorten the time of writing; The requirement of reduction to writing solves the efficiency of Chinese handwriting input.To such an extent as to also can carry out input in Chinese and retrieval more easily with Genius mouse.

Method of the present invention is the writing on the interface of the device that possesses Chinese hand-write recognition function arbitrarily, marks off some rectangle Chinese-character writings territory, and each Chinese-character writing territory is divided into several rectangle Hanzi components and writes the territory.According to the different structure characteristics of Chinese character, two or more Hanzi components are write the territory can be combined into the compound territory of writing of difform Hanzi component.Write certain parts of writing Chinese characters on the territory at the corresponding component in Chinese-character writing territory with pen or Genius mouse, by the Chinese character hand-written recognition system person's handwriting of the Hanzi component write is discerned, for the result who identifies, utilize the position component feature to infer relevant Chinese character; According to the position relation of Chinese character in word, infer corresponding word.Thereby realize purpose of the present invention.

Method of the present invention does not require that putting in order wordbook writes, and a Chinese character only need be write any one parts, and allows to omit the parts in arbitrary portion Chinese character and the Chinese character when the input word.In most occasions, the input of the word that input in Chinese is made up of two above Chinese characters.Method of the present invention is only required some parts of writing word, just can import whole word, thereby can reduce the amount of writing significantly, significantly improves input speed.Chinese character is complicated more, and the amplitude that input speed improves is big more, owing to only need write parts, writes burden thereby alleviated, and has reduced the identification difficulty relatively, makes discrimination obtain corresponding raising.Also just because of can the clipped parts to whole Chinese character, even write not entirely or the words that can not write, also can import.

Method of the present invention does not all have regulation parts and the obligato Chinese character that must write to any word, writes in the territory at the parts of Chinese character and can freely select to write parts, can freely omit whole Chinese character.This dirigibility causes the adaptability to concrete application and individual use habit.Write parts and omit word by adjustment, can obtain the input in Chinese optimum efficiency under the concrete environment for use.

Method of the present invention is retrieved for Chinese-character words, and a kind of means of quick fuzzy search are provided, as long as can write out certain part of Chinese character, promptly can effectively search corresponding Chinese character; As long as can write out some part of some or certain several Chinese character of word, just can effectively search corresponding word.

The invention will be further described below in conjunction with accompanying drawing.
