Description
Technical field
The present invention relates to a kind of Chinese character handwriting inputting method, particularly relate to a kind of Chinese character handwriting inputting method based on stroke sequence.
Background technology
At some mini-plants, as handheld device, in mobile unit and the industrial embedded system, standing have less screen and input tool, as a spot of button or small-sized touch-screen.At present the method for input Chinese character is loaded down with trivial details in above-mentioned mini-plant, and efficient is low, and need during input careful especially.
Similar with Chinese character input method on computers, the kinds of characters in the Chinese character set is to be complementary with different order of strokes.In mobile phone, the most frequently used a kind of input method of Chinese character be button by knocking respective sequence finding the Chinese character that needs, but this input method is very not directly perceived to the user who uses Chinese.Simultaneously, because in above-mentioned mini-plant, considerably less for the quantity of the button of importing, as button and the several function buttons of only a few that in mobile phone, have only 0-9, need the number of times of key tap very many during the input Chinese character, step is very loaded down with trivial details, the long and inefficiency of required time.In addition, make a choice in the different candidate Chinese characters on being presented at screen because the user has to usually, therefore, in whole Chinese character input process, user's notice has to concentrate on all the time on this display screen.
Another is more common, and the Chinese character input method that particularly is used on the PDA(Personal Digital Assistant) is handwriting input identification.In this Chinese character input method, the character that the user need use stylus to write complete required Chinese character usually on a small-sized sensing screen or sensor mat is discerned for system.Though this Chinese character input method is directly perceived and efficient height than last a kind of method, inconvenience is to carry this stylus.In addition, in operating process, the user needs the equipment of a hand-held residence bundle, and another holds this stylus and writes.Therefore, in this kind handwritten Chinese character input method, can't use one hand input, operation is comparatively inconvenient.
The novel mobile telephone of the handwritten Chinese character input method that write at the position that industry appearance now supports the use finger to be integrated with hot sensor mat above keyboard has solved the problem that need carry stylus.Yet what this handwritten Chinese character input method adopted is traditional Chinese character recognition technology, and the shape of the Chinese character that this technology is write according to the user and the information of structure are carried out whole identification to this character.Therefore, the user must write complete required Chinese character for identification in this sensitive zones.See also Fig. 1, need in this mobile phone, import " you " word, then must write complete character in sensitive zones (for example this square region) as the user.
Above-mentioned handwritten Chinese character input method exists following shortcoming:
1) owing to limit by the volume size of mobile phone, the area of the sensitive zones that the confession user writes is with respect to the finger of writing, and when being hold by one hand this mobile phone, normally thumb seems very limited; Therefore the user must write in this sensitive zones very carefully, difficulty was bigger when this made at writing stroke more or baroque Chinese character, and the common speed that has therefore reduced input, and in order to ensure writing at this sensitive zones, the user has to be primarily focused on it.
2) owing to be subjected to the length of thumb, volume, and the dirigibility of moving limits carries out one hand when importing on this mobile phone, as shown in Figure 3A, be difficult in this sensitive zones interior complete, clearly write required Chinese character.
Owing to exist above-mentioned shortcoming, when on mobile phone, using this kind handwritten Chinese character input method, be easy to occur the disappearance, unclear or overlapping of the stroke of the Chinese character write, thereby cause the speed of Chinese Character Recognition to reduce or cause identification error.Therefore, the input efficiency of this kind handwritten Chinese character input method still can not be satisfactory, and the fiduciary level of Chinese Character Recognition is not high when the most important thing is to carry out singlehanded input.
Summary of the invention
One object of the present invention is to propose a kind of Chinese character handwriting inputting method based on stroke sequence that uses the finger input on mini-plant.
Another object of the present invention is to propose a kind of Chinese character handwriting inputting method that is suitable for singlehanded input based on stroke sequence.
Another object of the present invention is to propose the high Chinese character handwriting inputting method of a kind of discrimination based on stroke sequence.
The Chinese character handwriting inputting method that the present invention is based on stroke sequence may further comprise the steps: discern the stroke of input character independently, produce stroke sequence; And list meet above-mentioned stroke sequence candidate characters for you to choose.The present invention ignores size and the position relation information between stroke and the stroke, and only according to described stroke sequence, i.e. ordinal relation information between stroke, and stroke and the stroke is discerned the character of input.
In preferred embodiment of the present invention, list the candidate characters that meets the stroke sequence condition in real time according to described stroke sequence, comprise just meeting the character of current stroke sequence fully and meeting current stroke sequence but also contain the character of other follow-up stroke sequences.Described candidate characters is selected from corresponding character set, and each character in this character set all comprises the stroke sequence information of self.Finish by importing an end of input signalisation system input, this moment, screen was only listed the candidate characters that just meets the stroke sequence condition fully.Perhaps do not carry out follow-up input above the schedule time after stroke of input, then produce the input of end of input signalisation system automatically and finish, this moment, screen was only listed the candidate characters that just meets the stroke sequence condition fully.The candidate characters that is presented at screen has numbering, selects by knocking corresponding digital keys for the user.Display screen and sensor are integrated, and select by the candidate characters that knocks on the screen.
Compare with more existing handwritten Chinese character input methods, the Chinese character handwriting inputting method that the present invention is based on stroke sequence has the following advantages:
1) user can directly carry out handwriting input with finger, has exempted the inconvenience of carrying stylus.
2) because hand-writing input method of the present invention is based on stroke sequence, complicated character can be decomposed into simple order of strokes input, even also can import easily and accurately for the zone of input is very little, is specially adapted to mini-plant.
3) because hand-writing input method of the present invention is not considered the space structure information of character, and only consider order between stroke itself and stroke and the stroke, therefore on mini-plant, use the present invention and can support singlehanded input operation well, except that selecting candidate characters, the user needn't be primarily focused in screen or the sensitive zones for input.

Embodiment
Different with the recognition methods based on whole Hanzi structure of the handwritten Chinese character input method of prior art, Chinese characters hand-written input method of the present invention is based on the independent stroke input sequence of Chinese character, and it comprises the steps:
The first step: discern the stroke of input character independently, produce stroke sequence.
Seeing also Fig. 2, is example with input " you " word, only needs in order respectively input " Pie ", " Shu ", " Pie ", “ Ya independently ", “ 亅 ", " Pie " and ", ".Because in the present invention is based on the Chinese character handwriting inputting method of stroke sequence, size between stroke and the stroke and position relation information are left in the basket, and only consider stroke, and the ordinal relation between stroke and the stroke, so the time need not consider the size of stroke and at the particular location (even overlapping) of this Chinese character in input, only need in this sensing scope, to import to get final product, import the minimum and the maximal value at the interval between two strokes and all can carry out self-defined.
Second the step: list meet above-mentioned stroke sequence candidate characters for you to choose.
The present invention is based in the Chinese character handwriting inputting method of stroke sequence, list the candidate characters that meets the stroke sequence condition in real time according to the stroke sequence that the above-mentioned first step produces, comprise just meeting the character of current stroke sequence fully and meeting current stroke sequence but also contain the character of other follow-up stroke sequences.Wherein, candidate characters is selected from corresponding character set, and each character in this character set all comprises the stroke sequence information of self.The putting in order of candidate characters that is presented at screen determines that by concrete algorithm typical a kind of aligning method is: the candidate characters that just meets current stroke sequence fully is a kind of class, before it is arranged in; Comprise current stroke sequence, but also comprise other follow-up stroke sequences few for another kind of class, its arrangement is taken second place; Comprise current stroke sequence, but also comprise other follow-up stroke sequences many be another kind of class, its arrangement is taken second place again; Wherein, the candidate characters in each class can just be arranged according to the frequency of its use again.Preferably, finish by importing an end of input signalisation system input, this moment, screen was only listed just complete qualified candidate characters; Wherein, this end of input signal can be to knock specific keys, double-click in sensitive zones or the operation of other equivalences.In addition, surpass the input of no longer carrying out other in the regular hour after stroke of input, then produce the input of end of input signalisation system automatically and finish, this moment, screen was only listed just complete qualified candidate characters.
In addition preferably, the candidate characters that is presented at screen has numbering, selects by knocking corresponding digital keys for the user; Perhaps screen and sensor are integrated, and select by the candidate characters that knocks on the screen.
Therefore, the present invention is based on the Chinese character handwriting inputting method of stroke sequence by application, can be quickly and easily, even use one-handed performance ground on mini-plant, to import Chinese character, wherein, can the said equipment can with for example integration such as touch sensor, thermal sensor, so that the sensitive zones for handwriting input to be provided.
See also Fig. 3 A and 3B, show the Chinese character handwriting inputting method that the present invention is based on stroke sequence among the figure respectively and be applied to example in mobile phone and the onboard navigation system, but be appreciated that ground, PDA, industrial embedded system and other need carry out in the equipment of Chinese character input, all can use the present invention and carry out the handwritten Chinese character input.
In sum, compare with more existing handwriting Chinese character input methods, the Chinese character handwriting inputting method that the present invention is based on stroke sequence has the following advantages:
1) user can directly carry out handwriting input with finger, has exempted the inconvenience of carrying stylus.
2) because hand-writing input method of the present invention is based on stroke sequence, complicated character can be decomposed into Simple order of strokes input, even also can import easily and accurately for the zone of input is very little, Be specially adapted to mini-plant.
3) because hand-writing input method of the present invention is not considered the space structure information of character, and only consider stroke Order between and stroke and the stroke itself, therefore using the present invention at mini-plant can be well Supported singlehanded input operation, except selecting candidate characters, the user needn't be primarily focused on screen or In the sensitive zones of person for input.
