Abstract
A technique for improving capacitive sensing accuracy. Concurrent activations of multiple capacitance sensors within an array of capacitance sensors are sensed. One of the concurrent activations of the multiple capacitance sensors is accepted as a user activation. Remaining ones of the concurrent activations of the multiple capacitance sensors are rejected based on their physical location within the array of capacitance sensors relative to the one of the concurrent activations of the multiple capacitance sensors accepted as the user activation.
