1. A method for human computer interaction comprising:

  • defining a virtual surface in three-dimensional space;

    defining a zone of restriction as an area or perimeter in X and Y dimensions that is a function of a Z coordinate in a Z dimension that extends in a forward direction from the human, the zone of restriction defining a sensitivity to movements of a human appendage, wherein the sensitivity to movements is reduced as the human appendage is moved forward relative to an origin that is a function of the location of the human;

    receiving input generated from a camera regarding the human appendage movement in the three-dimensional space;

    processing the input to generate processed gesture data;

    determining at least one physical attribute of the processed gesture data; and

    analyzing the at least one physical attribute of the processed gesture data to determine an interpreted action based upon a spatial relationship of the processed gesture data with respect to the virtual surface and the zone of restriction.
