Where is an object of interest with respect to the user’s head? In aug mented reality systems that use head-mounted displays (HMDs), knowing the relative position and orientation (pose) between object and head is cru cial for displaying a virtual object that is aligned with the real object. If the estimated pose of the object is inaccurate, the real and virtual objects may not be registered correctly. Registration inaccuracy is one of the most important problems limiting augmented reality applications [Azuma 97].
