1. A system for head pose tracking, comprising:

  • a group of sensors configured so as to be disposed on a user'"'"'s head, said group of sensors comprising a depth sensor apparatus used to identify the three dimensional locations of features within a scene sensed by the group of sensors, and at least one other type of sensor;

    a computing device; and

    a computer program comprising program modules executed by the computing device, wherein the computing device is directed by the program modules of the computer program to,periodically input data output by each sensor in the group of sensors,each time data is input from one or more of the sensors, use the inputted data to compute a transformation matrix which when applied to a previously determined head pose location and orientation established when the first sensor data was input identifies a current head pose location and orientation, andapply the transformation matrix to the previously determined head pose location and orientation to identify the current head pose location and orientation.
