  • Method for determining pressed location of touch screen
    Patent number: 8139038
    Abstract: A method for determining pressed locations of a touch screen, suitable for an electronic device having the touch screen, is provided. In the present method, coordinates and pressure values of m samples where the touch screen is pressed are detected. Then, the pressure values of those samples are compared to find n samples with the highest pressure values. Finally, the coordinates of those n samples are averaged for determining the pressed location of the touch screen. Accordingly, the accuracy of determining the pressed location of the touch screen can be increased and the convenience for operating the electronic device is enhanced.
