First embodiment
Fig. 1 illustrates the block schematic diagram of the contactor control device of one embodiment of the invention.Please refer to Fig. 1, the contactor control device 100 of present embodiment comprises a contact panel 110 and a controller 120.Controller 120 couples contact panel 110, and controller 120 comprises a detecting unit 124 and an identifying unit 122, and wherein identifying unit 122 couples detecting unit 124.
Fig. 2 illustrates on the part of the contact panel among Fig. 1 and looks synoptic diagram, and Fig. 3 illustrates the sensing method of touch control process flow diagram of the contactor control device of one embodiment of the invention.Please at first, contact panel 110 be scanned the touch-control coordinate (x, y) (the step S301) that are produced when touched with further detecting contact panel 110 with reference to Fig. 1, Fig. 2 and Fig. 3.In the present embodiment, detecting unit 124 can detect the touch-control coordinate that contact panel 110 produced when touched (x, y).
On the practice, controller 120 can further comprise a Z-axis processing unit 126a, a transverse axis processing unit 126b and a computing unit 126c, and wherein computing unit 126c couples Z-axis processing unit 126a, transverse axis processing unit 126b, detecting unit 124 and identifying unit 122.Computing unit 126c can see through the touch-control coordinate (x that touch position that Z-axis processing unit 126a and transverse axis processing unit 126b scanned calculates the touched position, y), and further (x y) is sent to detecting unit 124 and identifying unit 122 with the touch-control coordinate that calculated.
In the present embodiment, (x y) afterwards, can further add up touch-control coordinate (x, y) number of times of generation touching of contact panel 110 to the touch-control coordinate that detecting unit 124 is calculated at reception computing unit 126c.On the practice, in the detecting unit 124 action that a counter (not illustrating) adds up to touch number of times can be set further.
Then, detecting unit 124 can obtain a threshold values according to a certain special time and in order to the sweep frequency of detecting position of touch, and can (x y) number of times of touching takes place and obtains a judged result according to this threshold values and touch-control coordinate.
For instance, present embodiment hypothesis sweep frequency is contact panel 110 to be scanned in per 1/10 second, and hypothesis continues all to be in touched state in the special time of 1 minute (promptly 60 seconds) and is abnormal touch-control action, and just hypothesis is continued to touch and just is considered as abnormal touch-control when reaching at least 1 minute and moves.Based on above-mentioned hypothesis, can push away the threshold values that draws present embodiment is the quotients of 60 (seconds) divided by 1/10 (second/time), i.e. 600 (inferior).In following explanation, suppose under the action of abnormal touch-control touched touch-control coordinate (x
Err, y
Err) be bad point coordinate (x
Err, y
Err), it is that (x y) for example is judged to be bad point coordinate (x for 600 o'clock touch-control coordinate that the number of times that touching promptly takes place is not less than threshold values
Err, y
Err).
Shown in Fig. 4 A, in (k-1) inferior detecting result, touch-control coordinate (x as can be known
1, y
1), (x
2, y
2) and (x
3, y
3) be respectively (3,8), (12,15) and (16,9), wherein (x
1, y
1), (x
2, y
2) and (x
3, y
3) touched continuously respectively 597 times, 500 times and 12 times (step S303).Because touch-control coordinate (x
1, y
1), (x
2, y
2) and (x
3, y
3) three's touching number of times all do not reach 600 (step S305), so judge touch-control coordinate (x
1, y
1), (x
2, y
2) and (x
3, y
3) not bad point coordinate (x
Err, y
Err), that is this three place is regarded as normal touch-control action.
Then please see Figure 4B, in the k time detecting result, touch-control coordinate (x as can be known
1, y
1), (x
2, y
2), (x
3, y
3) and (x
4, y
4) be respectively (3,8), (12,15), (16,9) and (20,7).Wherein, (x
1, y
1), (x
2, y
2) and (x
3, y
3) three appeared at before once (promptly (k-1) is inferior) detecting result in, so this detecting result cumulative number be that the preceding cumulative number of once detecting the result adds 1 again, that is the touching number of times be respectively 598,501 and 13 (step S303); On the other hand, because (x
4, y
4) appear at first among this detecting result, so the touching number of times is 1 (step S303).Yet, because touch-control coordinate (x
1, y
1), (x
2, y
2), (x
3, y
3) and (x
4, y
4) four touching number of times does not all reach 600 (step S305), so this is regarded as normal touch-control action everywhere.
4C then with the aid of pictures again, in (k+1) inferior detecting result, touch-control coordinate (x as can be known
1, y
1), (x
2, y
2) and (x
4, y
4) be respectively (3,8), (12,15) and (20,7), wherein (x
1, y
1), (x
2, y
2) and (x
4, y
4) three appeared at before once (promptly the k time) detecting result in, so this detecting result cumulative number be that the preceding cumulative number of once detecting the result adds 1 again, that is the touching number of times be respectively 599,502 and 2 (step S303).Because touch-control coordinate (x
1, y
1), (x
2, y
2) and (x
4, y
4) three's touching number of times all do not reach 600 (step S305), therefore, this three place is regarded as normal touch-control action.Special one carry be, though touch-control coordinate (x
3, y
3) once detect among the result before once appearing at, but it does not occur thereby deleted in this detecting result.
Please see Figure 4D subsequently, in (k+2) inferior detecting result, touch-control coordinate (x as can be known
1, y
1), (x
2, y
2), (x
3, y
3) and (x
4, y
4) be respectively (3,8), (12,15), (16,9) and (20,7).Wherein, (x
1, y
1), (x
2, y
2) and (x
4, y
4) three appeared at before once (promptly (k+1) is inferior) detecting result in, so this detecting result cumulative number be that the preceding cumulative number of once detecting the result adds 1 again, that is the touching number of times be respectively 600,503 and 3 (step S303); On the other hand, though (x
3, y
3) appear at again this detecting result in, but its in preceding once detect made zero among the result thereby in this detecting result in again the counting be 1 (step S303).So continue accumulative total and touch number of times, do not add to describe at this.
Hold above-mentioned, touch-control coordinate (x
2, y
2), (x
3, y
3) and (x
4, y
4) three's touching number of times does not all reach 600 (step S305), so this three place is regarded as normal touch-control action.Yet, touch-control coordinate (x
1, y
1) the touching number of times reached 600 (step S305), thereby touch-control coordinate (x
1, y
1) be regarded as bad point coordinate (x
Err, y
Err).
In the present embodiment, judged result is bad point coordinate (x
Err, y
Err) coordinate figure (3,8).Then, identifying unit 122 can be according to above-mentioned judged result (i.e. bad point coordinate (3,8)), to set up in identifying unit 122 or to upgrade in order to store a database (not illustrating) of decision data.In the application of actual product, database can see through and buffer (not illustrating) is set reaches, and wherein to illustrate the stored judged result of buffer be bad point coordinate (3,8) (step S307) to Fig. 5.
Next, according to the stored judged result of the buffer in the database, identifying unit 122 can further judge whether to export above-mentioned touch-control coordinate (x
1, y
1), (x
2, y
2), (x
3, y
3) or (x
4, y
4).In the present embodiment, the foundation of judgement is the bad point coordinate (x that sees through in the database
Err, y
Err) position between the two the comparison action (step S309) touched with reality.
More particularly, because touch-control coordinate (x
2, y
2), (x
3, y
3) and (x
4, y
4) all not with bad point coordinate (x
Err, y
Err) (i.e. (3,8)) are identical, so identifying unit 122 output touch-control coordinate (x
2, y
2), (x
3, y
3) and (x
4, y
4) (step S311).Otherwise, because touch-control coordinate (x
1, y
1) and bad point coordinate (x
Err, y
Err) identical, so identifying unit 122 is not exported touch-control coordinate (x
1, y
1) (step S313).
From the above, whether the touch position that detected of present embodiment decidable is abnormal touch action.In case when abnormal touch action took place for certain ad-hoc location or some ad-hoc location, the action relevant with this ad-hoc location just can not be performed, and then avoid this ad-hoc location of contact panel 100 to carry out misoperation.In addition, because the contactor control device 100 of present embodiment is after the existence of allowing above-mentioned ad-hoc location, still has good errorless touch controllable function, review traditional contactor control device and can only take to repair or give up and need not wait the mode that does not meet cost of manufacture, present embodiment then has the advantage of saving man-hour and reducing cost.
What deserves to be mentioned is that present embodiment further is provided with a storer 128 that is coupled to detecting unit 124 in controller 120.When contactor control device 100 shutdown, the data in the database are (as bad point coordinate (x
Err, y
Err)) but unloading to storer 128.In addition, when contactor control device 100 was started shooting once more, the data in the storer 128 were (as bad point coordinate (x
Err, y
Err)) can be read out and be stored in the database.Thus, contactor control device 100 just need not to detect again again and judges existing bad point coordinate (x before the start this time
Err, y
Err) why, this measure is not only saved and is judged bad point coordinate (x again
Err, y
Err) time, also avoid judging bad point coordinate (x again
Err, y
Err) process in unnecessary misoperation takes place.
Second embodiment
From another perspective, the technological means of the foregoing description can be summarized the process flow diagram of another kind of sensing method of touch control, as shown in Figure 6.Converge the sensing method of touch control of whole present embodiment simply at this, and be described as follows: at first, in step S601, the touch-control coordinate that the detecting contactor control device is produced when touched.Then, in step S603, in a special time, judge whether the touch-control coordinate is continued touching, and use acquisition one judged result.Afterwards, in step S605,, set up a database according to judged result.All the other details and advantage as for the sensing method of touch control of present embodiment have been included among above-mentioned first embodiment, so do not add tired stating at this.
In sum, sensing method of touch control of the present invention can be judged the state of this touch-control coordinate after detecting touch-control coordinate, further to avoid carrying out misoperation in subsequent step through detecting unit and identifying unit in the contactor control device.Generally speaking, adopt the contactor control device of sensing method of touch control of the present invention that the situation that misoperation takes place is improved thereby have good touch-control sensing ability.
