Abstract
A method for detecting multiple touch positions on a touch panel includes the steps of: periodically scanning the touch panel; when detecting a first touch position at a first time during scanning the touch panel, recording coordinates on a first dimensional direction and a second dimensional direction of the first touch position; continuingly scanning the touch panel after the first time; and when detecting a plurality of new possible touch positions at a second time, determining a second touch position from the new possible touch positions according to the recorded coordinates on the first and second dimensional directions of the first touch position.
