I tried a demo in which a photo appeared – a jungly scene with a wooden footbridge just in front of me. The theme from “Jurassic Park” played crisply in my right ear. (Cute, real cute.)

But as I looked left, right, up or down, my view changed accordingly, as though I were wearing one of those old virtual-reality headsets. The tracking of my head angle and the response to the immersive photo was incredibly crisp and accurate.

That is interesting.
