Claim 11:
12. The method of claim 9, wherein estimating the relative pose of the at least one user-interaction controller with respect to the HMD comprises:
processing the controller-pose-tracking data to determine a pose of the at least one user-interaction controller in its local coordinate system;
processing the HMD-pose-tracking data to determine a pose of the HMD in a global coordinate system;
converting the pose of the at least one user-interaction controller from said local coordinate system to the global coordinate system; and
determining the relative pose of the at least one user-interaction controller with respect to the HMD, based on the pose of the at least one user-interaction controller in the global coordinate system and the pose of the HMD in the global coordinate system.
