1. A method of behavior recognition, comprising the steps of:

  • storing a dynamic motion model representative of designated human behaviors in a form of differential equations having position and velocity components;

    sensing at least one human subject to be analyzed;

    representing the body of the subject as a plurality of connected, non-deformable links;

    determining the dynamic motion of the body, if any, by monitoring the position of the links in space as a function of time;

    using the dynamic motion to derive kinematic link relationships at specific body locations;

    comparing the kinematic link relationships to the position and velocity components; and

    , if a match is found,outputting the results of the comparison as the designated behavior.
