Abstract
A pressure sensitive stylus, comprises a movable tip that recedes within a housing of the stylus in response to user applied contact pressure, wherein a displacement of the tip along an axis on which it recedes is a function of the applied contact pressure, and an optical sensor enclosed within the housing for optically sensing the displacement of the tip and for providing output in response to the sensing.
