Abstract:
A system for computer user interface, comprising:(a) an energy source disposed for producing a sensing field within a closed area in a first plane when the energy source is operated; (b) a sensor disposed in a second plane that is different from the first plane for monitoring the closed area and producing electronic information corresponding to user action within the closed area in the first plane that causes at least a portion of the sensing field within the closed area to be redirected towards the sensor when the sensor is operated; and (c) a computer electronically connected to the sensor, the computer receiving electronic information produced by the sensor when the computer is operated, the computer including logic which analyzes electronic information received from the sensor and produces output signals corresponding to user action within the closed area, wherein the energy source is located on a steering wheel of a vehicle and the sensor is located on an instrumental panel of the vehicle.
