[summary of the invention]
So the present invention develops for solving above-mentioned existing issue, its purpose is, provides according to the operation species of utilizing Touch Screen, if pin the contact of keyboard and so on repeatedly and disconnect action, response speed is accelerated; If continue to pin a point or keep under the state of contact, do the continued operation of outlet and circle and so on, just strengthen noise filtering, be the response speed control method for touch of the Touch Screen that improves stability.
For achieving the above object, the present invention comprises the steps the characteristics of constituting: after detecting the initial contact of Touch Screen, till the some positional informations that detect appointment, the step of each cached location information that detects in arrangement, if the positional information that is stored in above-mentioned arrangement reaches the some of appointment, just the positional information of last detection is appended on arranging, and elimination is stored in the positional information of arrangement at first, keep the step of the positional information that is stored in arrangement of some, during each detection position information, obtain the average of the positional information aggregate value that is stored in above-mentioned arrangement, till the contact of Touch Screen disconnects, with the step of the final position information output of that time.
The present invention is according to the operation species of utilizing Touch Screen, is intended to the invention of control response speed, and in general Touch Screen is with sample position, certain hour interval information, and the sampled data of average some, uses as a location information data.Therefore according to operation species, in the time of need pinning the very fast response speed of keyboard and so on, reduce the equalization quantity of sampled data; Continue to pin a point or carry out line and during continuous touchs of circle and so on, the equalization quantity of increase sampled data, with this method of touch-responsive speed that Based Intelligent Control Touch Screen is provided as emphasis.
That is,, when pinning the operation of the very fast response speed of needs of key and so on,, reduce the equalization quantity of sampled data, improve response speed compared with noise filtering by Touch Screen; Continue to pin a point or carry out line and during continuous touchs of circle and so on, compared with response speed, the equalization quantity of increase sampled data provides and is intended to strengthen the method for noise filtering as emphasis.
As mentioned above, the response speed control method for touch of Touch Screen of the present invention has such effect.That is,,, response speed is accelerated if pin the contact of key and so on repeatedly and disconnect action according to the operation species of utilizing Touch Screen; If continue to pin a point or keep under the state of contact, carry out the continued operation of line and circle and so on, just strengthen noise filtering, improve stability.

[embodiment]
Below with reference to accompanying drawings embodiments of the invention are elaborated.
Fig. 2 is the precedence diagram of expression Touch Screen response speed control method for touch of the present invention.As shown in Figure 2, Touch Screen is after the time point from initial contact begins certain number of times continuous detecting positional information (sampled data), on average exporting as final position information of its value, but prior art is after the positional information of the certain number of times of whole detections, has just exported final position information.
But the present invention is till the positional information that all detects predetermined number of times, and an average detected goes out the positional information of quantity, directly exports as final position information.That is, suppose average 8 positional informations, as final position information output, existing situation is after unconditionally 8 positional informations all being detected, just to export final position information; But the present invention is, if detect a positional information, just it directly exported as final position information, if detect two positional informations, just the mean value of two values exported as final position information.With same reason, if detect three positional informations, just the mean value of three values is exported as final position information, till detecting eight positional informations, continue to carry out this process.
Afterwards, as mentioned above, begin all to detect eight positional informations from the point of initial contact after, disconnect till the contact, eliminate the positional information that stores the earliest, append new positional information successively, continue average eight positional informations, export as final position information.
So the present invention is that if after finishing the initial contact of Touch Screen, its contact does not disconnect, and just increases the equalization number of times of sampled data gradually, finally continues the positional information of average some, strengthens noise filtering with this; If it is such to pin key operation, Touch Screen comes in contact at any time and disconnects, and when just detecting positional information, the positional information of an average detected quantity is suitable for as final position information, can improve response speed with this at every turn.
Below with reference to the concrete action of the present invention of the flowchart text of Fig. 2.
The present invention is average about eight times sampled data, uses as a location information data.That is, the initialization parameter (on average) that is intended to count the parameter (counting) of eight sub-sampling data and is intended to the sampled data of average above-mentioned amount detection is 0.
Afterwards, when detecting positional information (X, Y data) at every turn, when increasing by one of above-mentioned parameter (counting, average) respectively, as shown in Figure 3, till eight positional informations of whole detections, each cached location information after arranging (data _ (x) y) [counting], is obtained its aggregate value (total _ (x) y).
Afterwards, the aggregate value of above-mentioned positional information is divided by parameter (on average), obtains the mean value of the positional information that is stored in arrangement (data _ (x) y) [counting], exports as final position information.At this moment, the parameter (on average) that is intended to average above-mentioned positional information is if the positional information that detects is eight, just keeps eight, but parameter reached before eight, and its quantity is identical with the positional information quantity of detection.
That is, eight cached location information of detection arrive arranges till (data _ x (y) [1]～data _ x (y) [8]), and parameter (on average) is along with detection position information, be increased to 7 from 1, if but all detect eight positional informations, and just keep eight, obtain the average of positional information.But the counting that is stored in the positional information of above-mentioned arrangement is to continue to increase, and nearest positional information is appended arranging, and eliminates the positional information that stores the earliest, makes arrangement keep eight positional informations (data _ x (y) [N-7]～data _ x (y) [N]) all the time.
So if after finishing initial contact, before eight positional information accumulative totals, its contact does not disconnect, and just continues average eight sampled datas, uses as final position information; Before eight positional informations accumulative total, it contact disconnections, when forming other contact, and during the information of each detection position, the final position information till output that time, so can be according to the kind of Touch Screen operation, raising stability and response speed.
