OPTICAL NAVIGATION DEVICE WITH HAPTIC FEEDBACK

摘要

An optical joystick (100) is connected to a vibratory transducer (108) such as a piezoelectric transducer, where the vibratory transducer produces vibration which may be perceived upon a surface (202) of the optical joystick. The vibration is perceived primarily at the surface (202) of the optical joystick (100)., and not upon a case (400) of the computing device, and is distinguishable from other vibrations which may be induced in the computing device. Vibrations are created to indicate scrolled items in a list, selected items (406), or navigation within certain displayed zones.
