Have a look at exhibits A and B (Figures 1 and 2), taken from various sites reporting about this project, and, I assume, PR material released by the people behind the project. They are blatant lies. The technology described on the Holovision web site can definitely not produce what’s shown in these concept images (because that would be impossible). Look at the actual description of the Holovision technology. What’s the first thing they write about, and what’s in the first figure? A screen. A very clever screen, at that: each pixel is not a simple light emitter, but an active element that can emit different amount of light in different directions, somewhat like a lighthouse or the kind of laser used in a laser light show. Having a screen of such active pixels can indeed create what the Holovision site claims: glasses- and head-tracking-free, multi-viewer, holographic 3D. It’s very difficult to make look good in practice, but it’s feasible.
