Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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…
