Tilt Determination

A capacitance module may include a substrate, a set of electrodes formed on the substrate where a first generally linear electrode of the set may be aligned with a second generally linear electrode of the set; a controller in communication with the set of electrodes; and memory having programmed instructions configured to cause the controller, when executed, to measure a change in capacitance; and determine a tilt of an object in proximity to the substrate based, in part, on the measured change in capacitance.
