The second embodiment
The hardware structure of the second embodiment in essence hardware structure with the first embodiment is identical, its difference part is, in a second embodiment, the touch control detection device is to detect first the audio input signal that input tool produces, and then the touching input signal that produces according to this audio input signal and same input tool comes this input tool of identification and touching behavior thereof.By this, the touch control detection device can produce corresponding special applications instruction according to above-mentioned identification result, significantly promotes touch control detection device diversity in the use.
Fig. 3 is the process flow diagram according to the shown touch control detecting method of the second embodiment of the present invention.Please refer to Fig. 1 and Fig. 3, in step S302, the audio input signal that sound detection circuit 16 detects on the touch control unit 15.Then, in step S304, sound detection circuit 16 judges whether to detect audio input signal, if sound detection circuit 16 does not detect audio input signal, and after step S304, sound detection circuit 16 repeated execution of steps S302.
In step S304, if sound detection circuit 16 detects audio input signal, then in step S306, control circuit 19 judges whether the audio input signal that detects meets default sound model.For instance, control circuit 19 can with the sound model of the audio input signal that detects sequentially with storage circuit 18 in a plurality of default sound model compare, and judge its whether identical or similar in these default sound models at least one of them.By this, control circuit 19 can judge effectively whether the relevant information of the input tool that produces this audio input signal has been recorded in storage circuit 18.If control circuit 19 judges that the audio input signal that detects does not meet default sound model, after step S306, sound detection circuit 16 repeated execution of steps S302.
In addition, in step S306, if control circuit 19 judges that the audio input signal that detects meets default sound model, then in step S308, control circuit 19 records this audio input signal and time of origin thereof in storage circuit 18.And in step S310, in the permission time range that control circuit 19 is judged behind this time of origin, whether touching testing circuit 17 detects the touching input signal.
Below will utilize Fig. 4 to illustrate among the step S310 of Fig. 3, but control circuit judge whether touch testing circuit detects the implementation step of touching input signal.
Fig. 4 is according to the shown process flow diagram that judges whether to detect the touching input signal of the second embodiment of the present invention.Please refer to Fig. 1 and Fig. 4, in step S402, touching testing circuit 17 detects the change amount of touch-control sensing value in a permission time range on the touch control unit 15, the wherein corresponding user of touch-control sensing value or the touch position of input tool on touch control unit 15.For instance, explain take capacitive touch control unit 15 as example, the touch-control sensing value on the capacitive touch control unit 15 can be the value of coupling capacitance, and coupling capacitance normally produces because of user's touch action.Particularly, mention that at this change amount of touch-control sensing value for example is the change amount of above-mentioned coupling capacitance.
Then, in step S404, the change amount of the touch-control sensing value that control circuit 19 judgement touching testing circuits 17 detect in allowing time range (for example, the change amount of coupling capacitance) whether detect level greater than touching, wherein touching detection level is the default sound model that meets corresponding to the audio input signal that sound detection circuit 16 had before detected.In addition, the touching that different default sound models is corresponding detects level may be not identical.For instance, take corresponding to the default sound model of nail touching touch control unit 15 and corresponding to the default sound model that refers to abdomen touching touch control unit 15 as example, in general the area that nail touching touch control unit 15 produces refers to that the area that abdomen touching touch control unit 15 produces is little.Therefore, the touching of nail touching touch control unit 15 detects level and can set the touching that refers to abdomen touching touch control unit 15 and detect level and come lowly.Yet the present invention is as limit, and the touching that each default sound model is corresponding detects in fact viewable design demand and being adjusted of level.
In step S404, if control circuit 19 is judged the change amount of touch-control sensing value and is detected level greater than touching, then in step S406, control circuit 19 is judged that testing circuits 17 have and is detected the corresponding touching input signal of the audio input signal that had before received corresponding to sound detection circuit 16 in allowing time range.In addition, in step S404, if control circuit 19 is judged the change amount of touch-control sensing value and is not detected level greater than touching, then in step S408, control circuit 19 judges that testing circuit 17 does not detect the corresponding touching input signal of the audio input signal that had before received corresponding to sound detection circuit 16 in allowing time range.
It is worth mentioning that the permission time range of mentioning is that audio input signal is synchronous with the touching input signal in step S310.In other words, after sound detection circuit detects audio input signal, if in allowing time range, if the touching testing circuit detects the touching input signal, represent that this touching input signal and audio input signal are by same touching behavior generation, and so that the audio input signal that is detected first can be used as the usefulness (that is, the audio input signal that is detected first is useful signal) of aid identification, please continue the explanation with reference to figure 5.
Whether Fig. 5 is for detecting the synoptic diagram of touching input signal in allowing time range according to the shown judgement of the second embodiment of the present invention.Please refer to Fig. 5, sound detection circuit 16 detects audio input signal 501 at time t1, and audio input signal 501 continues to be detected in time interval T1 (for example, 100 milliseconds).Therefore, among the permission time range T after time t1, whether effectively whether touching testing circuit 17 detects the touching input signal will be related to audio input signal 501 (that is whether the audio input signal 501 that, detects first can be used as the usefulness of aid identification).In addition, in the present embodiment, allow the time range T can be greater than 100 milliseconds and less than 500 milliseconds (for example, 200 milliseconds), and the present invention be to its restriction, the time span that allows time range T viewable design demand and adjusting on practice.For example, will allow time range T to shorten to 80 milliseconds, to reduce False Rate.
Then, touching testing circuit 17 detects touching input signal 502 at time t2, and touching input signal 502 continues to be detected in time interval T2 (for example, 100 milliseconds).At this, because time t2 is contained among the time t1 permission time range T afterwards, so it is to be produced by same touching behavior once that touching input signal 502 can be judged with audio input signal 501, and so that audio input signal 501 is judged as effectively, and can be used as the follow-up foundation of distinguishing input tool.
Please referring again to Fig. 1 and Fig. 3, in step S310, if in allowing time range, touching testing circuit 17 does not detect the touching input signal, it is invalid that the audio input signal that before detected this moment is judged as, and after step S310, sound detection circuit 16 repeated execution of steps S302.In addition, if in allowing time range, touching testing circuit 17 (for example detects the touching input signal, the touching input signal 502 of Fig. 5), then in step S312, control circuit 19 comes identification input tool and touching behavior according to default sound model identical after the above-mentioned comparison and the touching input signal that detects.For instance, suppose that the sound model of the audio input signal that control circuit 19 judgements detect is identical with the default sound model of representative " finger-joint ", control circuit 19 can identify the input tool that produces this audio input signal and be " finger-joint ".In addition, control circuit 19 from click location corresponding to the touching input signal that detects, click duration or sliding distance and can learn the touching behavior of input tool.
Then, in step S314, control circuit 19 can be according to the input tool that picks out and touching behavior and the instruction of combination results special applications.For example, when control circuit 19 picks out input tool for " finger-joint " and touching behavior during for " clicks ", the special applications instruction of control circuit 19 generations for example is " cutting " instruction for clicked file.Again for example, when control circuit 19 picks out input tool for " finger nail " and touching behavior during for " clicks ", the special applications instruction of control circuit 19 generations for example is " deletion " instruction for clicked file, and the present invention is not as limit.For instance, when the user clicks touch control unit 15 with finger-joint, its corresponding special applications instruction that produces can be " pressing right mouse button ", and when the user scraped touch control unit 15 up or down with finger nail, its corresponding special applications instruction then can be " up or down roll mouse roller ".Other application facet, for example finger nail is in order to cut photo, finger abdomen in order to mobile photo or file opening.In another example, control circuit 19 picks out the touching behavior when " pictures ", and no matter input tool why, all carries out " restoring upper one moves " instruction.
It should be noted that the special applications instruction can be produced by control circuit 19, but also can produce at processor 11.Specifically, control circuit 19 only records and transmits effective audio input signal and touches input signal to processor 11, is converted to the special applications instruction by processor 11 again.
In addition, present embodiment also can be supported the touching input signal of a plurality of touch position, and for example, when surrounding one when regional with the nail of five fingers at touch control unit 15, corresponding special applications instruction for example is with All Files deletion in this zone.
In other words, above-mentioned special applications instruction is based on the kind of input tool and the combination definition of touching behavior forms, and corresponds to specific function, and it can make various changes according to the demand on design or the practice.In addition, on the implementation, control circuit 19 can be set a plurality of Contact recognition codes (contact idenfication, CID), and each Contact recognition code is corresponded to an input tool.By this, when control circuit 19 needed to produce the special applications instruction, it can inquire about Contact recognition code corresponding to audio input signal, produced corresponding special applications instruction with foundation Contact recognition code and touching behavior.
The 3rd embodiment
The hardware structure of the 3rd embodiment is identical with the first embodiment in essence, and the touch control detecting method of the 3rd embodiment is similar to the touch control detecting method of the second embodiment, its difference part is, in the 3rd embodiment, if the touch control detection device is judged its audio input signal that detects and is not met any default sound model that the touch control detection device can produce elementary instruction according to its touching input signal that detects.By this, do not having audio input signal can be used in the situation of auxiliary identification, the touch control detection device still can be kept basic running, to promote touch control detection device elasticity in the use.In other words, the function of above-mentioned elementary instruction is for deciding according to basic touching behavior.
Fig. 6 is the process flow diagram according to the shown touch control detecting method of the third embodiment of the present invention.Please refer to Fig. 1 and Fig. 6, in step S602, the audio input signal that sound detection circuit 16 detects on the touch control unit 15.Then, in step S604, sound detection circuit 16 judges whether to detect audio input signal, if sound detection circuit 16 does not detect audio input signal, and after step S604, sound detection circuit 16 repeated execution of steps S602.
In step S604, if sound detection circuit 16 detects audio input signal, then in step S606, control circuit 19 judges whether the audio input signal that detects meets default sound model.If control circuit 19 judges that the audio input signal that detects does not meet default sound model, after step S606, sound detection circuit 16 repeated execution of steps S602.
In addition, in step S606, if control circuit 19 judges that the audio input signal that detects meets default sound model, then in step S608, control circuit 19 records this audio input signal and time of origin thereof in storage circuit 18.And in step S610, in the permission time range that control circuit 19 is judged behind this time of origin, whether touching testing circuit 17 detects the touching input signal.If in allowing time range, touching testing circuit 17 does not detect the touching input signal, after step S610, sound detection circuit 16 repeated execution of steps S602 and will be recorded in audio input signal in the storage circuit 18 be considered as invalid.In addition, if in allowing time range, touching testing circuit 17 (for example detects the touching input signal, the touching input signal 402 of Fig. 4), then in step S612, control circuit 19 comes identification input tool and touching behavior according to default sound model identical after the above-mentioned comparison and the touching input signal that detects.Then, in step S614, control circuit 19 can be according to the input tool that picks out and the instruction of touching behavior generation special applications.
On the other hand, in step S606, if control circuit 19 judges that the audio input signal that sound detection circuit 16 detects does not meet any default sound model, then in step S616, control circuit 19 judges whether touching testing circuit 17 detects the touching input signal.If touching testing circuit 17 does not detect the touching input signal, after step S616, sound detection circuit 16 repeated execution of steps S602.In step S616, if touching testing circuit 17 detects the touching input signal, then in step S618, control circuit 19 produces elementary instruction according to the touching input signal that detects.For instance, elementary instruction can be the click of the click of single position, a plurality of positions, single position length by the length of, a plurality of positions by or the touching behavior corresponding basic operation instruction out of the ordinary such as towing.
The 4th embodiment

In step S704, if sound detection circuit 16 detects audio input signal, then in step S706, control circuit 19 judges whether the audio input signal that sound detection circuit 16 detects meets default sound model.If control circuit 19 judges that the audio input signal that detects does not meet default sound model, after step S706, sound detection circuit 16 repeated execution of steps S702.
In addition, in step S706, if control circuit 19 judges that the audio input signal that sound detection circuit 16 detects meets default sound model, then in step S708, control circuit 19 records this audio input signal and time of origin thereof in storage circuit 18.Then, in step S710, touching testing circuit 17 detects the change amount of touch-control sensing value in a permission time range on the touch control unit 15.And, in step S712, control circuit 19 is according to the change amount of above-mentioned touch-control sensing value in allowing time range, and the touching of upgrading corresponding default sound model (that is, the audio input signal that detects of sound detection circuit 16 meet default sound model) detects level.By this, when time sound detection circuit 16 detected another audio input signal and its and meets above-mentioned default sound model instantly, the touching after control circuit 19 can upgrade according to this detected level and judge whether to detect corresponding touching input signal.
It is worth mentioning that, in above-mentioned the second embodiment to the four embodiment, the touch control detection device all is to detect first audio input signal, and then comes this input tool of identification and touching behavior thereof according to this audio input signal and touching input signal corresponding to input tool.Yet under specific hardware condition or program execution enviroment, for the touching behavior of an input tool, the touch control detection device may detect first the touching input signal of its generation, just can continue to receive it and produce audio input signal.Therefore, the present invention also proposes to touch input signal as the basis, and the audio input signal of arranging in pairs or groups again please refer to following the 5th embodiment as the touch control detection device of auxiliary judgment condition.
