Abstract: There is provided a method for preventing accidentally triggering edge swipe gestures adapted to a touch control system including a touch surface. The method includes the steps of: recording first information when a first gesture is detected to end at a periphery of the touch surface; recording second information when a second gesture is detected to start at the periphery of the touch surface; and determining, by a processor, whether to trigger an edge swipe gesture of the touch control system according to the first information and the second information.
