I saw a launch demo of this in Mumbai comic con last weekend. Note that they only had a pre-rendered game video running that could be paused with spacebar. There were two cameras checking the observers eyes and creates a double image for depth. The 3D didn't feel very as deep as movies with Polaroid glasses, but it was clear and evident, especially on a still image. I inquired about the tech behind it and the sales guys didn't really know much, except the keywords (eye tracking, AI tech, 2 camera). I was curious on how the AI would be able to differentiate the depth especially at that refresh rate they promise (1-2ms). They mentioned having an app which can convert ANY game or movie into 3D. After a rabbit hole of a research into this, I got some answers in the 3D tech but not how the cameras are used, and the speed of the AI remains very questionable.
