Claim 16:
17. The method of claim 15, wherein the step of determining the pose of the at least one controller in the global coordinate space comprises:
processing HMD-pose-tracking data generated by an HMD-pose-tracking means for determining a pose of the HMD in the global coordinate system;
determining a position of the at least one light source in the global coordinate space, based on the pose of the HMD in the global coordinate system, and the distance between the at least one camera and the at least one light source; and
estimating a position and an orientation of the at least one controller in the global coordinate space, based on the position of the at least one light source in the global coordinate space, a pre-known geometry of the at least one controller, and an orientation of the representation of the at least one controller in the at least one image.
