Abstract:
A touch sensitive display includes a capacitive touch sensor configured to output capacitance values. A motion sensor makes a motion detection and generates a motion signal including a motion value indicative of sensed motion detection. A touch detection circuit is coupled to receive the capacitance values and motion values. The touch detection circuit processes the capacitance values to make a hovering detection and a touching detection with respect to the display. The touch detection circuit further generates an output signal including the motion value correlated in time with each of the hovering detection and touching detection. The output signal may be processed as a user interface control signal. The output signal may also be processed to determine an impulsive strength of the touching detection as a function of an elapsed time between hover and touch and the measured motion values.
