Patent ID: 8358226

Claim:
A method for indicating actuation of a capacitive button comprising at least three sensor electrode elements, said method comprising: receiving indicia from at least three distinct sensor electrodes, each sensor electrode of said at least three distinct sensor electrodes associated with at least one sensor electrode element of said at least three sensor electrode elements comprising said capacitive button, said indicia indicative of interaction of an input object with said capacitive button; and identifying said capacitive button from a plurality of capacitive buttons, said plurality of capacitive buttons sharing at least one sensor electrode of said at least three distinct sensor electrodes; determining actuation of said capacitive button based at least in part on satisfaction of a set of criteria, said set of criteria comprising: a location condition concerning a location of said input object relative to a center of said capacitive button, wherein said location of said input object is gauged at least in part based on said indicia; and a coupling condition concerning a magnitude of change in capacitive coupling of said at least three distinct sensor electrodes, wherein said coupling condition comprises said magnitude of said change in capacitive coupling satisfying a first threshold magnitude, wherein said magnitude of said change in capacitive coupling of said at least three distinct sensor electrodes is gauged at least in part based on said indicia.
