1. A system for detecting a hand orientation, comprising:

  • a sensor for detecting a hand of a user in free space;

    a processing apparatus, operatively coupled to the sensor, the processing apparatus being configured todetect a plurality of surface points of the detected hand;

    process the plurality of surface points to determine if the plurality of surface points of the detected hand are arranged in at least one of a substantially concave area relative to the sensor, and/or a substantially convex area relative to the sensor;

    identify the detected hand as a palm of the hand directed towards the sensor if the processing apparatus determines the plurality of surface points of the detected hand are arranged in a substantially concave area relative to the sensor; and

    identify the detected hand as a back of the hand directed towards the sensor if the processing apparatus determines the plurality of surface points of the detected hand are arranged in a substantially convex area relative to the sensor.
