Abstract
Methods for determining actuation of a capacitive button are described. In some embodiments, indicia from the at least three distinct sensor electrodes associated with at least three sensor electrode elements comprising the capacitive button are received, the indicia indicative of interaction of an input object with the at least three distinct sensor electrodes. The actuation of the capacitive button is then determined, based at least in part on satisfying a set of criteria comprising: a location condition concerning a location of the input object relative to a center of the capacitive button, and a coupling condition concerning a change in capacitive coupling of the at least three distinct sensor electrodes associated with the at least three sensor electrode elements comprising the capacitive button.
