Abstract:
A pointing device for detecting motion relative to a surface includes a transmitter configured to emit an electromagnetic signal toward the surface. The pointing device further includes a receiver configured to receive a reflection of the electromagnetic signal from the surface. The pointing device further includes a processor configured to determine the motion based on a Doppler-shift between the electromagnetic signal and its reflection.
