Abstract
A device stores running baseline measurements and initial baseline measurements for a plurality of touch sensors. The device repeatedly takes measurements from the touch sensors during device operation, and counts a number of positive transitions of the measurements, and counts a number of negative transitions of the measurements, the transitions relative to the stored initial baseline measurements. The device re-initializes the stored initial baseline measurements if and only if the count of negative transitions differs from the count of positive transitions by a predetermined amount (a 'negative touch state').
