Claim:
1. A method for suppressing position change in a detected image of touch to assist in distinguishing tapping motions from sliding motions on a touch sensor panel, comprising: measuring a position change per frame of the detected image of touch to obtain a detected position change per frame; utilizing a change in capacitance detected at a node in the touch sensor panel, computing a suppressed position change per frame for the detected image of touch utilizing a time instability function, representing a varying amount of suppressed position change over time independent of the detected position change per frame; and utilizing the suppressed position change per frame for the detected image of touch to assist in distinguishing tapping motions from sliding motions on the touch sensor pane, the suppressed position change operative to suppress a displayed movement of an object at or near the touch sensor panel.
