How does the display work?
We project high-speed (4,320 frames per second) video of different views of the face onto a spinning mirror. As the mirror spins, the different views are reflected to all different viewpoints around the display. In our teleconferencing system, seventy-two views of the face rendered by a PC with a modern graphics card are projected across 180 degrees field of view. By the time the mirror rotates to reflect images from one eye position to another, a different view of the scene is projected, so the result appears to be three-dimensional.
