1. A method of recognizing gestures for real-time interaction, comprising:

  • capturing three-dimensional (3D) data on a subject;

    detecting a pointing action by the subject from the 3D data;

    computing an initial estimate of a target region from the pointing action, the initial estimate of the target region having a defined radius around a center point;

    tracking the pointing action of the subject and performing a series of iterations wherein the defined radius of the target region changes based on the detected pointing action; and

    providing feedback to the subject by highlighting a portion around the initial estimate and continuously modifying the highlighted portion until the highlighted portion shrinks to a single point indicating that a desired location has been reached.
