  • Method and device for accuracy enhancement of touchscreen input
    Patent number: 9857907
    Abstract: Disclosed is a method of processing an input of a touch screen in an electronic device. The method includes detecting a pointing region indicated by a pointing means on the touch screen. The method also includes changing a selection number of input coordinates to be selected when the pointing region is changed. The method also includes calculating a corrected coordinate by using input coordinates stored in a memory as many as the changed selection number. The method also includes performing a function corresponding to the corrected coordinate.

  • Input apparatus and input method of a portable terminal using a pen
    Patent number: 9507461
    Abstract: An input apparatus of a portable terminal and an input method for compensating an input from a pen to increase the accuracy of the pen are provided. The input apparatus includes a touch panel configured to generate an input signal according to a pen touch, a memory configured to store at least one lookup table in which data for compensating an error of a pen input according to a user's pen usage characteristic is stored, a controller configured to detect an input coordinate of the pen touch on the touch panel and configured to extract compensation data from the lookup table corresponding to the input coordinate to compensate the error of the pen input, and a display unit configured to display a compensated pen input signal.
