Abstract
A method for position detection is adapted to a sensing device. The sensing device includes a plurality of sensing blocks arranged in a 2D array, with each block having a plurality of sensing points arranged in a 2D array. The method includes conducting a block-scan to determine if a touched block exists, and conducting a point-scan to obtain a touched point if the touched block exists. In order to obtain a touched point, the sensing device applying the method conducts a block-scan within the sensing area and then a point-scan within the touched block instead of point-scanning the whole sensing area. Accordingly, the sensing device could obtain the touched point faster than before.
