Abstract
An electronic device may include a housing having a mousing surface, and a navigation device carried by the housing and comprising a proximity detector. The proximity detector may include a single photon avalanche diode (SPAD) configured to detect movement of an activator adjacent the mousing surface. For example, the proximity detector may detect movement along three axes.
