OPTICAL NAVIGATION DEVICE WITH HAPTIC FEEDBACK
First Claim
Patent Images
1. A navigation device comprising:
- an optical navigation sensor having a surface, the optical navigation sensor operative to sense movement of an object in contact with the surface; and
a vibratory transducer operative to produce vibration responsive to an electrical signal, the transducer positioned to propagate the vibration to the surface of the optical navigation sensor.

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.

21. A method of indicating a sensed gesture, comprising:
-
sensing a movement with an optical navigation sensor having a surface; comparing, using a processor, a location of an indicator with a location of a displayed object enabled for vibration when an indicator is near or over the displayed object; and activating a vibratory transducer operative to produce vibration for predetermined time periods, the transducer positioned to propagate the vibration to the surface of the optical navigation sensor when the indicator is near or over the displayed object and the gesture is sensed.
