Palmer Luckey of Oculus LLC has noted that the company plans to offer the headtracker that will come with the Oculus Rift HMD as a standalone purchase for those interested in other offerings. It's quite tiny, wireless, and plugs in through USB. It would be easily attached to the HMZ-T1 or HMZ-T2 to turn it into a proper head mounted display for virtual reality use. Details about the tracker here:
