Abstract
An embodiment of the present invention is directed to a method for rejecting sensor information when a switch is being pressed in a system having sensors over switches. A switch in the process of being pressed may be determined based on an increase in pressure which may be determined by measuring the increase in capacitance at a plurality of capacitive sensors. The rejection of sensor information when the switch is being pressed allows the user interface to more accurately thus facilitates smooth and jitterless interface operation.
