  • Portable device and orientation detection method therefor
    Patent number: 9037433
    Abstract: An embodiment of the invention provides an orientation detection method for a portable device. The method comprises acquiring an accelerometer data, determining whether the portable device is in a flat status, determining whether the portable device is in a stable status, and when the portable device is determined in both the flat status and the stable status, stopping acquiring the accelerometer data until receiving an enable signal.
    Type: Grant

  • 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.
