A device includes a time-of-flight sensor configured to transmit an optical pulse signal and to receive a return optical pulse signal corresponding to a portion of the transmitted optical pulse signal that has reflected off an object within a field of view of the time-of-flight sensor. The time-of-flight sensor generates a range estimation signal including a distance to the object and a signal amplitude indicating an amplitude of the return optical pulse signal. A controller is coupled to the time of flight sensor and is configured to process the range estimation signal over time to detect an input gesture based upon the signal amplitude and estimated distance.
