Claim 2:
3. The controller-tracking system of claim 1, wherein the system further comprises an HMD-pose-tracking means, and wherein when determining the pose of the at least one controller in the global coordinate space, the at least one processor is configured to:
process HMD-pose-tracking data generated by the HMD-pose-tracking means to determine a pose of the HMD in the global coordinate system;
determine 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
estimate 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.
