Abstract
A method for detecting a magnitude of force applied to a capacitive sensor array may comprise receiving a plurality of capacitance measurements affected by a contact at a touch-sensing surface, and determining a magnitude of a force applied to the touch-sensing surface at a location of the contact based on the location of the contact and a capacitance measurement of the first plurality of capacitance measurements.
