  • Lift detection adapted for navigation on a transparent structure
    Patent number: 7442916
    Abstract: A pointing device such as an optical mouse is equipped with a top surface lift detection system that is able to provide lift detection whether the pointing device sits on a transparent structure or on an opaque structure. The top surface lift detection system relies on the separate detection of a light beam that reflects off the surface upon which the pointing device sits to detect lift whether the pointing devices sits on an opaque surface or a transparent surface.
