HIGH RESOLUTION NON-GHOSTED GESTURES

摘要

A method of performing a two-finger gesture when the absolute position of the fingers does not need to be known in order to perform the gesture, wherein de-ghosting of results from a touch sensor that gives a false position and a real position for each actual finger on the touch sensor is performed by finding a strongest signal when performing a short aperture measurement from one side of the touch sensor so that the direction of a rotation gesture can be determined, and wherein flick and pinch gestures can all be calculated using de-ghosted weighted average and weighted absolute deviation calculations.
