Abstract:
A gesture sensing device having a single illumination source is disclosed. In one or more implementations, the gesture sensing device includes a single illumination source configured to emit light and a light sensor assembly configured to detect the light reflected from an object and to output time dependent signals in response thereto. The gesture sensing device also includes a processing circuit coupled to the light sensor assembly and configured to analyze the time dependent signals received from the light sensor assembly to determine object directional movement proximate to the light sensor assembly.
