First Claim
Patent Images
1. A solid-state object position detector for indicating a desired user interface navigation task, comprising:
- a touch sensor having a plurality of electrodes disposed in a substantially closed loop, said touch sensor configured to sense an object proximate to said substantially closed loop; and
a processor coupled to said touch sensor, said processor configured to provide relative motion information about said object moving proximate to said substantially closed loop, said relative motion information representative of a difference between a first position and second position of said object, said relative motion information indicating said desired user interface navigation task.

Abstract
The present disclosure discloses an object position detector. The object position detector comprises a touch sensor formed as a closed loop and having a physical constraint formed on an upper surface of the touch sensor and coextensive with the closed loop. The touch sensor is configured to sense motion of an object proximate to the closed loop. The object position detector also comprises a processor coupled to the touch sensor and is programmed to generate an action in response to the motion on the touch sensor.
