Abstract
A technique for operating a capacitive sensor array is described. The technique includes measuring a first capacitance of a first set of electrodes at a first time, measuring a second capacitance of a second set of electrodes at a second time, and calculating a position of a conductive object based on a relative magnitude of the first capacitance and the second capacitance. The first set and the second set includes at least one electrode in common and at least one electrode that is not in common.
