Abstract
A device may include a capacitance sensor; an overlay positioned near the capacitance sensor, the overlay including a touch surface opposite to an underside of the overlay, where the underside is positioned near the capacitance sensor; a controller; memory in communication with the controller and including programmed instructions that, when executed, cause the controller to detect a proximity value of an object with a capacitance sensor, where a touch surface is located between the capacitance sensor and the object; determine a planar radial distance of the object away from a predetermined location on the touch surface; and change the proximity value based, at least in part, on the planar radial distance.
