Description
The present invention relates generally to the data inputting interface, in more detail, relates to the character recognition interface that each character wherein contains the large character set of one or more strokes.
The machine recognition of people personal letter is a very difficult problem, along with nearest calculating and electron device quick-fried suddenly with pen, has more become one major issue to be suggested.There are many different calculating and electron device can receive handwriting input.So-called (Pen-based) product with pen, for example, computing machine, and personal digital assistant, and the like product, a touch-sensitive screen is arranged basically, the user can apply personal letter in the above.These devices will be write in one's own hand input digitization then.Other device, computing machine for example, high-grade telephone set, Digital Television and other information processing devices then comprise or can one of access can receive the digitizing table of personal letter input.Also have the other device that can receive the input of personal letter character with fax, scan input, Email, or other methods such as electronic data transfer.The information content of these device process informations and the input of attempt identification personal letter; Usually, these devices to be revised errors in processing and in order to discern the input of personal letter character information are shown to the user in order to feed back.
When the character of identification limited quantity, for example, during the character set of 100 following characters, the identification of personal letter input has many means.Usually bad work when but these means are used in the character set that changes complex characters in a large number.Be difficult to rapidly and accurately with personal letter input identification that the example of the large character set of identification is some ideographic character/lexigraphies such as the simplified and Chinese character traditional font, Japanese and other have the literal of large character set.Some literal such as simplified Hanzi are made up of thousands of characters.
Traditional interfacial process, as keyboard input, input is always very difficult based on data and text that the literal of a large amount of characters provides with this class; Be complicated to a certain extent because the amount of character set is big.In addition, many such literal are in order to adopt the pinyin representation of the character in west with the keyboard input character.Therefore the input of the keyboard-type of these characters is difficult.Based on the keyboard input that is Chinese character of an example of the difficulty of the literal keyboard of large character set input.In order to use the Chinese characters for keyboard inputting data, or text, at first will be the literal Roman capitalsization.The character in west commonly used as Britain's big belly lattice Shandong Anglo-Saxon letter, comes the pinyin representation Chinese character, is referred to as phonetic (Pinyin).Therefore want that the people with Chinese characters for keyboard inputting data or text must understand phonetic earlier and shows with wanting the english character with Chinese character equivalence on voice of keyboard input for one.
Running into another difficulty with traditional keyboard interface input identification based on the data of the literal with large character set or text handwriting input is that the same character of many such literal has one or more forms of expression, that is, the block letter and the cursive script of similar Britain big belly lattice Shandong Anglo-Saxon letter.In addition, such literal has unisonance, and for example Chinese character just has the identical and meaning of many pronunciations and writes different homonyms.Therefore, same phonetic may be relevant with many characters, and the people of input character data must often optionally select the table from one.
Say that typically the literal that the interface tech that is used for the following limited character set data input of hundred characters is used the large character set of several thousand a hundreds ofs variation complex characters can not obtain result accurately.The many interface tech of data input such as handwriting recognitions of small size character set literal of being used for are very slow if be used for the large character set literal.
Therefore because the increase of using the electronics entering apparatus of pen to use, difficulty to the keyboards input of the various literal that contain a large amount of and complicated character set, need a kind of rapid, accurately, method and apparatus is as various literal easily, complicated, the large character set literal, the character recognition interface of symbol and digital handwriting input.
