Abstract
An optical joystick is connected to a vibratory transducer such as a piezoelectric transducer, where the vibratory transducer produces vibration which may be perceived upon a surface of the optical joystick. The vibration is perceived primarily at the surface of the optical joystick, and not upon a case 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, or navigation within certain displayed zones.
