2Classification, its quantitative classification quantity of arranging in pairs or groups the again G of group
1Classification, with decision singly refer to gesture STG serve as occur simultaneously be associated singly refer to gesture, and do not limit classified order in class condition.In addition, be example with quantity P=1～3 of trigger signals in the foregoing description, in fact other quantity P also can be to referring to that singly gesture STG is categorized as other and singly refers to gesture, and do not limit at this.In addition, touch-control sensing control chip 302 also can be according to P trigger signals TR
0～TR
P-1Included like other characterisitic parameters such as touch point pressure, directions, with the classification of other gesture group of classifying, with decision singly refer to gesture STG serve as occur simultaneously be associated singly refer to gesture, and do not limit quantity and kind in above-mentioned class condition.
In a concrete example, when 302 decisions of touch-control sensing control chip refer to that singly gesture STG is classification C
11, C
22The page turning gesture that is associated of common factor after, can be again according to leaving touch point T
1With initial entering touch point T
0Coordinate decision touch-control moving direction with the G of direction group that classifies
3Be first to fourth classification C
31～C
34, refer to singly that with decision gesture STG is and classification C
11, C
22The page turning gesture left that is associated of common factor or page turning gesture to the right, upwards page turning gesture or page turning gesture downwards.
In another concrete example, operate under the different mode at main frame 304, identical classification is occured simultaneously can correspond to the different gestures of clicking.For example, be operating in when main frame 304 under the reading model of e-book, touch-control sensing control chip 302 is detected 1 subsequent triggers signal TR in reference time Tref
1Institute's correspondence is left touch point T
1With initial entering touch point T
0Distance during greater than reference distance Dref, decision refers to that singly gesture STG is classification C
11, C
22The page turning gesture that is associated of common factor.Yet if main frame 304 is operating in a window scheme, touch-control sensing control chip 302 changes referring to that singly gesture STG decision is classification C
11, C
22The slip gesture (slide) that is associated of common factor, leave behind the moving cursor certain distance again after promptly clicking with known sliding action.
In fact, operate under the different mode at main frame 304, identical classification is occured simultaneously also can carry out the difference running.For instance,, receive when package Pac indication one refers to that singly gesture STG is the slip gesture if main frame 304 operates in a window scheme, only can be with cursor mobile phase respective distances; And if main frame 304 receives that earlier package Pac indication one refers to that singly gesture STG occurs on the object for the towing gesture; This moment, main frame 304 can begin to operate in a drag mode; Another refers to that singly gesture STG is the slip gesture then to receive another package Pac indication again, then can be related to this object mobile phase respective distances.
Above-mentioned each embodiment singly refers to the gesture determination methods, can reduce one and refer to that singly gesture judges flow process 60, and shown in the embodiment of Fig. 6, it may further comprise the steps:
Step 600: beginning.
Step 602: detect P trigger signals TR0～TRp-1.
Step 604: according to P trigger signals TR0～TRp-1, judge P trigger signals TR0～
Indivedual classifications of the Q kind gesture G1～Gq of group under the TRp-1.
Step 606: the indivedual classifications according to the Q kind gesture G1～Gq of group that is judged, decide P
One of individual trigger signals TR0～TRp-1 representative singly refers to gesture STG.
Step 608: finish.
Wherein the details of each step can be analogized and got by the operation of the corresponding assembly of touch-control sensing control chip 302, does not give unnecessary details at this.
Comprehensively above-mentioned; Known technology must be detected the time parameter of several corresponding time periods under the different touch-control situations, and it is compared with corresponding time parameter respectively, is which kind of singly refers to gesture according to different judgement time condition judgment again; Therefore not only need detect considerable time parameter; And none method in common judges and all singly refers to gesture, if add the parameter combinations of distance, can cause judgement to refer to that singly the calculating formula of gesture crosses huge, complicated.In comparison; The foregoing description can be under the operation that does not change the definition that originally singly refers to gesture operation and main frame; By one or more trigger signals of detecting,, determine indivedual classifications of one or more gesture group again according to the characterisitic parameter (like quantity, distance, direction etc.) of one or more trigger signals; With decision singly refer to gesture serve as occur simultaneously be associated one singly refer to gesture, and can decide the various gestures that singly refer to according to general Rule of judgment simply.
The above is merely the preferred embodiments of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
