Embodiment
In order to make those skilled in the art person understand better the scheme of the embodiment of the present invention, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.
Because the stroke number of generally letter, numbers and symbols is less and similar character is many, handwriting input recognition effect is often limited, thereby tends to key-press input more.And due to the restriction of inputting interface size, dissimilar character often takies same button as letter, numeral, symbol etc., thereby prior art need to carry out the switching at different interfaces when the dissimilar symbol of input, to activate dissimilar button.
Restriction for the synchronous input method of existing multi-mode to continuous input word string type, the embodiment of the present invention has proposed the method and system of the synchronous input of a kind of new multi-mode, not only can on same interface, receive user's key-press input and handwriting input, but also can receive user, the non-button that enlivens button is switched to input etc., and realize the effective parsing to input word string by automatic decision, realized the continuous input of word string.
A kind of inputting interface that the embodiment of the present invention realizes the synchronous input method of multi-mode and system as shown in Figure 3.
In embodiments of the present invention, input pattern comprises: key-press input pattern, handwriting input mode and button switch input pattern, and described button switches input pattern and refers to the input that enlivens button (as " abc " button top non-status of a sovereign character " 2 " in Fig. 3) to non-.
As shown in Figure 4, be the process flow diagram that the embodiment of the present invention realizes the method for the synchronous input of multi-mode, comprise the following steps:
Such as, by touch screen information recording, be two-dimensional coordinate point sequence (x, y) chronologically, x wherein, y is respectively horizontal ordinate and the ordinate of each sampled point.
Particularly, can be stroke action or press action according to described two-dimensional coordinate point sequence judgement user's touch screen operation.If stroke action, determine that it is that handwriting input mode or button switch input pattern that described stroke moves corresponding input pattern; If press action, described in determining, pressing input pattern corresponding to action is that key-press input pattern or button switch input pattern.
In general, when user does stroke action, the person's handwriting displacement collecting in the unit interval is longer, and user presses while moving, and in the unit interval, on touch-screen, person's handwriting displacement is often shorter.Therefore, in actual applications, can be first according to touch screen information the displacement within the unit interval determine user action.
Particularly, can be in default judgement time T 1, to time per unit, (conventionally the T1=n* unit interval, each unit interval can be 100ms.) the interior sample relation that relatively sampled point is accumulated displacement S and judging distance S1.If S>S1, is defined as stroke action; Otherwise for pressing action.
Be judged as under stroke operating state, the user's touch screen information collecting often has larger displacement, its corresponding input pattern may be handwriting input mode or button switching input pattern (also have the action of certain hour stroke because button switches input mode, and have such possibility: user keeps in touch state and stays for some time).In this case, also needing further to distinguish is that handwriting input mode or button switch input pattern.
Because hand-written character stroke has its specific writing rules conventionally, and button switching input is set in advance by system conventionally, therefore, can to it, distinguish according to the presentation direction feature of stroke in embodiments of the present invention.Particularly, can judge the relation that direction d and direction scope dt between maximum moving distance two sampled points occur in unit judgement interval detection time, if d in direction scope dt, is judged as button switching input pattern; Otherwise be judged as handwriting input mode.
Press under operating state being judged as, the displacement of the user's touch screen information collecting is generally less, and its corresponding input pattern may be that key-press input pattern or button switch input pattern.In this case, also needing further to distinguish is that key-press input pattern or button switch input pattern.
Due under key-press input pattern, the time that user contacts specific keys is often shorter and accumulation displacement is less, otherwise the button time of button blocked operation is conventionally long or accumulation displacement is larger.For this reason, in actual applications, can to it, further distinguish from duration of contact and shift length.Particularly, can be in default judgement time T 2, to the sample in time per unit, relatively sampled point is accumulated the relation of displacement S and judging distance S2.If S>S2, is defined as button and switches input pattern; If S<=S2 but time of producing this section of displacement have surpassed judgement time T 2, be defined as button and switch input pattern; Other situations (be S<=S2 but time of producing this section of displacement do not surpass T2) are all judged as key-press input pattern.
It should be noted that, above-mentioned being judged as, press under operating state, situation about finishing if there is a stroke, is judged as key-press input pattern.
Before mention, in embodiments of the present invention, input pattern has three kinds, respectively: key-press input pattern, handwriting input mode and button switch input pattern.For these three kinds of input patterns, can adopt respectively corresponding recognition method to obtain recognition result.Particularly:
If input pattern is handwriting input mode, described touch screen information is carried out to handwriting recognition, obtain corresponding text word string;
If input pattern is key-press input pattern, according to the location positioning of described touch screen information corresponding enliven button, then obtain the described text word string that button is corresponding of enlivening;
If described input pattern is button switches input pattern, according to the location positioning of described touch screen information with the non-position key in key mapping, then obtain character (as letters/symbols/numeral) the upper screen display that described non-position key is corresponding and show.
It should be noted that, above-mentioned each parameter can arrange when system initialization, comprises the first judgement time T 1, the second judgement time T 2, once judges time interval t, the first judging distance S1, the second judging distance S2, direction scope dt.In general, the setting of these parameters depends on the size of display screen sampling rate, the speed of hardware processor and the framework of system software etc.In actual applications, consider user's writing experience and actual effect, the first judgement time T 1 can be taken as to 200ms; The second judgement time T 2 is taken as 500ms; Once judge that time interval t is taken as 50ms; The first judging distance S1 is 20 pixels; The second judging distance S2 is 30 pixels; Direction scope dt is (75 °, 105 °), as shown in black region in Fig. 6.
