Abstract
In emitting and extinguishing periods, emitting and extinguishing projected electromagnetic radiation is alternated, the emitted projected electromagnetic radiation defining a radiation region adjacent to a housing. Sensed electromagnetic radiation within respective fields of view of first and second sensors is detected, the sensed electromagnetic radiation including ambient electromagnetic radiation detected during the emitting and the extinguishing periods, and projected electromagnetic radiation reflected off an object in the radiation region during the emitting period. Indicia of a position of the object with respect to the housing is output.
