Claim 1:
2. The tracking system of claim 1, wherein, when it is identified that the operational state of the at least one light source that is visible in the at least one image is that the at least one light source is deactivated, the at least one processor is further configured to:
control the plurality of light sources such that each of the plurality of light sources is activated;
process at least one next image of the real-world environment, captured by the at least one camera, to identify an operational state of one or more light sources that are visible in the at least one next image, wherein the at least one next image is indicative of the actual relative pose of the at least one user-interaction controller with respect to the HMD; and
correct the estimated relative pose of the at least one user-interaction controller with respect to the HMD to determine the actual relative pose of the at least one user-interaction controller with respect to the HMD, based on the operational state of the one or more light sources.
