Comment Tracking (Score 3) 69
The tracking device looks like a slightly modified RingMouse (now called the Owl by some resellers, I think.) It uses ultrasound time of flight, emitted from the tracker and received by three speakers, to track 3D position, and an infrared receiver for button clicks.
I sincerely doubt that the tracking is being used to adjust the lens (be it holographic or lenticular, I don't know.) Even with a perfect lens, you want to track the position and orientation of the head so that you can adjust the 3D rendering view accordingly. Without the headtracking, the image of the object will distort as you move away from the sweet spot, i.e., the point in real space that corresponds to the virtual view point. With the head tracking, the object appears to remain still, and you can move back and forth to get parallax, look at the sides, etc. With a full 6DOF tracker, you can even tilt your head and the view remains perfect. With the tracker used here, you will not be able to do that.
