Method of optimizing touch detection

Abstract:

A computer-implemented method is disclosed. The method includes: receiving a first signal from a first sensor of the device, the first signal indicative of a grounding condition of the device; setting one or more touch detection thresholds based on the grounding condition; receiving a touch signal from a touch sensor of the device, the touch signal indicative of a touch by an object; and determining whether one or more parameters of the touch signal exceeds the one or more touch detection thresholds.
