All the head moving made me think back to Jonny Lee's wiimote headtracking 3d display.

Perhaps Amazon have an eye tracking system which can do the same with out the need for the user to be wearing infra red leds?

Yeah I was coming here to say the same thing. Seems like it is definitely doing some sort of motion tracking.

I'm actually thinking this is either "Kinect" on a tablet and/or eye tracking. The application specifically talks about additional sensors. being used to build apps. I'm not sure head tracking is a strong use case for additional apps. But something with the depth of MS's Kinect or eye tracking could be really interesting.

I've never seen that video before, so thanks for posting it.

Yes, the head movement in the Amazon video makes it look like head tracking/perspective changes built in to the device. But what for?
