Description
Technical field
The present invention relates to Chinese character input method and Chinese character input equipment, relate in particular to based on Chinese character input method that handwriting input is discerned and Chinese character input equipment.
Background technology
In the reality, people often use conventional ITU-T keyboard to carry out the information input.In addition, handwriting input input also has been widely used in the portable input equipment such as mobile phone or PDA(Personal Digital Assistant).Such as, the user can pass through writing pencil, the handwriting input zone that contact Chinese character input equipment provides, detect the relative motion that writing pencil streaks the handwriting input zone by the Chinese character input equipment, thereby identify the content of user's input, and it is presented on the display screen of Chinese character input equipment.
In order to improve the speed of handwriting input, further developed a kind of being called the handwriting input mode of " dual area input ".The Chinese character input equipment is by providing two handwriting input zones, make the user to carry out handwriting input in a handwriting input zone therein earlier, when the Chinese character input equipment is discerned this handwriting input, in another handwriting input zone, carry out handwriting input again, Using such method is used alternatingly two handwriting input zones, thereby make the user time to be identified such as need not, and can carry out handwriting input continuously, improved the speed of handwriting input.About the synoptic diagram of " dual area input " handwriting input mode as shown in Figure 1.
In Fig. 1, the employed Chinese character input equipment of user (not shown) provides two handwriting input zones 11 and 12.In first step, the user at first in the first hand-written input area 11 the handwriting input Chinese character " in ".In second step, when Chinese Chinese character input device identification Chinese character " in " time, the user can be at the second hand-written input area 12 input Chinese characters " state ".In the third step afterwards, in the Chinese character " state " of Chinese character input equipment identification input, the user again can be in the next Chinese character "Yes" of first hand-written input area 11 inputs.
At present, Chinese character input method based on " dual area input " mainly is based on the individual character recognition mode, the action that this recognition mode marks in the handwriting input zone at the user, to may store by corresponding alternative Chinese character, arrange with close degree handwriting input according to that determine in some way, and show selection for the user.Under the situation that the user selects, the Chinese character input equipment shows the alternative Chinese character of first demonstration as recognition result.Because writing pencil contact handwriting input zone and the relative motion of being done thereon and each one writing style have much relations, therefore this relative motion more complicated normally, thereby cause under this recognition mode based on individual character, first alternative Chinese character just is that the accuracy (the first alternative word discrimination) of required input Chinese character only is about 85% in the given alternative Chinese character tabulation.That is to say that for other Chinese characters of 15%, the user must be by need determining the Chinese character of input to the further selection of alternative Chinese character tabulation.
The speed that this first lower alternative word discrimination has greatly influenced Chinese handwriting input, particularly utilized " dual area input " to carry out Chinese handwriting input.Be example with the Chinese word of the handwriting input shown in Fig. 2 " China " below, specify the shortcoming of utilizing " dual area input " to carry out Chinese handwriting input under the above-mentioned individual character recognition mode.
As shown in Figure 2, in first step, at first in the first hand-written input area 11 input first Chinese character " in ".Afterwards, in second step, discern at the Chinese character input equipment " in " in, the user is at the second hand-written input area input Chinese character " state ".At third step, Chinese character in the first hand-written input area " in " handwriting input be identified as Chinese character " Shen ".And this moment second Chinese character " state " also handwriting input is not finished.Like this, find that the user of first Chinese character identification error will attempt to delete the Chinese character of identification error " Shen ", this causes in the 4th step uncompleted handwriting input to Chinese character " state " also is identified as Chinese character " Fujian " mistakenly.At this moment, in the 5th step, the user has to delete two Chinese characters " Shen Min " by wrong identification, thereby carries out the handwriting input of " China " again in the 6th step.By each step shown in Figure 2 as can be seen, this process not only consuming time and also repeatedly the input situation under be easy to make mistakes, thereby cause great inconvenience to the user.
In order to address this problem, some hand-written recognition method provides a kind of association function.It is this that the hand-written recognition method of association function is provided is the information of utilizing Chinese word, the Chinese word that may form according to the Chinese character of input earlier, list next candidate's Chinese character for the user, so that allow the user therefrom select easily, thereby reduced the identification error that may occur when handwriting input is discerned effectively.
Yet, on the basis that this association function must can be correctly validated at first Chinese character of Chinese word, could association go out correct follow-up Chinese character, improve the recognition correct rate of this Chinese word subsequent words, therefore, this function still can't solve the lower problem of the first alternative word discrimination to first Chinese character in the Chinese word language.
