Abstract: Head pose tracking technique embodiments are presented that use a group of sensors configured so as to be disposed on a user's head. This group of sensors includes a depth sensor apparatus used to identify the three dimensional locations of features within a scene, and at least one other type of sensor. Data output by each sensor in the group of sensors is periodically input, and each time the data is input it is used to compute a transformation matrix that 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. This transformation matrix is then applied to the previously determined head pose location and orientation to identify a current head pose location and orientation.
