Abstract
An electronic device includes a housing enclosing a motion sensor and a first capacitive proximity sensor on a first planar side of the electronic device. A second capacitive proximity sensor on a second planar side of the electronic device within the housing is monitored for determining the differential amount of signal change of the first capacitive proximity sensor relative to the second capacitive proximity sensor.
