1. A hand controller apparatus of the type used for generating a computer input, the apparatus being ergonomically shaped to minimize hand muscle fatigue even during a protracted period of continuous use;

  • the apparatus comprising the following elements;

    (a) an arched metacarpal-phalangeal support surface upon which to rest the mid-palm of the hand;

    (b) a concave thenar support surface upon which to rest the thenar pad of the hand;

    (c) a substantially flat hypo-thenar ledge surface upon which to rest the hypo-thenar portion of the hand;

    (d) an arched distal phalange support surface upon which to rest the distal volar pad of the forefinger;

    (e) a concave lateral depression upon which to rest the distal volar pad of the thumb;

    (f) a medial ledge upon which to rest the middle phalanges of the ring and small fingers, the bottom of the medial ledge being concavely shaped to receive the distal volar pads of those two fingers; and

    (g) a concave depression between the medial ledge and the arched distal phalange support surface for receiving the distal volar pad of the middle finger;

    (h) each of said elements (a) through (g) being integrally arranged to form a continuous hand-bearing hollow housing enclosed by a substantially planar member for stable engagement with an underlying surface.
