Abstract

The present invention proposes a kind of method for improving electric capacity touch screen and clicking on accuracy, comprises the following steps：1）Obtain the touch screen area of finger hand capacity touch screen；2）Obtain peak, minimum point, ultra-left point and the rightest point of touch screen area；3）Highs and lows are connected；Ultra-left point connects with rightest point, obtains a crosspoint；4）The round touch screen area reconstructed is drawn by the center of circle of crosspoint；5）Using the touch screen area of reconstruct as touch screen valid region.The present invention improves the method that electric capacity touch screen clicks on accuracy, improves existing touch screen and clicks on accuracy, realization is correct to be clicked on, and operation is clear and definite.

Description

A kind of method for improving electric capacity touch screen and clicking on accuracy

Technical field

The invention belongs to the embedded software hardware development field of mobile communication terminal, coordinates capacitance touch screen to realize a kind ofThe method for improving touch screen precision.

Background technology

Nowadays the smart mobile phone of the mobile terminal capacitance touch screen in market is more and more, such mobile phone operation is simple, functionIt is powerful.But for the thicker people of finger, existing touch-screen mobile phone is not well in view of the tactile of such crowdShield accuracy problem, often occur that the situation of mistake is hit in touch point, the greatly user of puzzlement and bad luck is brought to userExperience.

The content of the invention

In order to solve the technical problem in the presence of background technology, the present invention, which proposes, improves electric capacity touch screen click accuracyMethod, improve existing touch screen and click on accuracy, realize it is correct click on, operation is clear and definite.

The present invention technical solution be：A kind of method for improving electric capacity touch screen and clicking on accuracy, its special character existIn：It the described method comprises the following steps：

1）Obtain the touch screen area of finger hand capacity touch screen；

2）Obtain peak, minimum point, ultra-left point and the rightest point of touch screen area；

3）Highs and lows are connected；Ultra-left point connects with rightest point, obtains a crosspoint；

4）The round touch screen area reconstructed is drawn by the center of circle of crosspoint；

5）Using the touch screen area of reconstruct as touch screen valid region.

Above-mentioned steps 4）By touch screen area, peak and minimum point, ultra-left point and rightest point, two lines section are connected respectivelyCrosspoint be used as the center of circle draw circle, round radius be less than two lines segment length average value, specifically adjusted according to actual conditions,Drawn circle is exactly the touch screen area reconstructed.

Above-mentioned steps 4）Round radius is less than the average value of two lines segment length, is specifically adjusted according to actual conditions.

The present invention in mobile terminal side touch-screen by adding the corresponding use for judging, can improving the thick people's touch screen of fingerFamily is experienced, more flexibly intelligent compared with existing touch screen operation mode, lifts user's use feeling.By to user's touch screenArea, which is done, to be judged, can be improved existing touch screen and be clicked on accuracy, realize correct click, operation is clear and definite, compares mechanical keyMore flexible, Consumer's Experience is more excellent.Screen taps mode at this stage, increase newly confirm sentencing for click location on this basisDisconnected, more practical and novel, more hommization, the angle used from user removes the transmission user instruction of fast explicit.

Brief description of the drawings

Fig. 1 is finger touch screen area of the present invention schematic diagram；

Fig. 2 is reconstruct schematic diagram in finger touch screen area of the present invention；

Embodiment

Referring to Fig. 1, Fig. 2, a kind of method for improving electric capacity touch screen and clicking on accuracy, comprise the following steps：

1）Obtain the touch screen area 1 of finger hand capacity touch screen；

2）Obtain peak A, minimum point C, ultra-left point B and the rightest point D of touch screen area 1；

3）Peak A is connected with minimum point C；Ultra-left point B connects with rightest point D, obtains a crosspoint O；

4）Using crosspoint O as the center of circle, circle is drawn.The radius for drawing circle is X pixel（X is less than AC, and BD connection line lengths are put downAverage）；The touch screen area 2 reconstructed；By touch screen area, central point is obtained using algorithm, and then reconstruct touch screen area；

5）Using the touch screen area 2 of reconstruct as touch screen valid region.

Claims (1)

1. A kind of 1. method for improving electric capacity touch screen and clicking on accuracy, it is characterised in that：It the described method comprises the following steps：
