1. A system for providing a positional input value to an electronic device, the system comprising:

  • a sender portion adapted to be manipulated by a user to specify a target point within a target area, the sender portion including a light projecting system adapted to project a beam of light including a predefined spatially varying characteristic at the target area;

    a receiver portion including at least one sensor unit, the sensor unit is adapted to measure at least one value of the spatially varying characteristic of the beam of light at the location of the sensor unit, wherein the receiver portion includes logic adapted to determine a positional input value associated with the target point from the value of the spatially varying characteristic at the location of the sensor unit.
