1. A method for head pose estimation, comprising:

  • receiving block motion vectors for a frame of video from a block motion estimator;

    selecting at least one block for analysis;

    determining an average motion vector for the at least one selected block;

    combining the determined average motion vector with average motion vectors from past frames of video to obtain an accumulated average motion vector;

    estimating the orientation of a user'"'"'s head in the video frame based on the accumulated average motion vector; and

    outputting at least one parameter indicative of the estimated orientation.
