Claim 1:
2. The controller-tracking system of claim 1, wherein when determining the pose of the at least one controller in the global coordinate space, the at least one processor is configured to:
determine image coordinates of the at least one image segment in the at least one image;
determine a position of the at least one light source in the global coordinate space, based on the distance between the at least one camera and the at least one light source, the image coordinates of the at least one image segment, and transformations between the image coordinates and the global coordinate space; 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.
