Abstract:
1. A system, comprising: a touch sensitive display including a capacitive touch sensor configured to output values indicative of sensed capacitance; a motion sensor configured to make a motion detection and generate a touching detection correlated motion signal and a baseline detection motion signal, each including a motion value indicative of the sensed motion detection; a touch detection circuit coupled to the capacitive touch sensor and the motion sensor, the touch detection circuit configured to process the values indicative of sensed capacitance and make a hovering detection and a touching detection, wherein the hovering detection is correlated with the motion value of the baseline detection motion signal and the touching detection is correlated with the motion value of the touching detection correlated motion signal; and wherein the touch detection circuit further configured to generate an output signal including each of the motion value correlated in time with a detection indication of the at least one hovering detection and touching detection and the values indicative of sensed capacitance and an impulsive strength determined from the correlated motion value of the baseline detection motion signal and the correlated motion value of the touching detection correlated motion signal.
