Apple 3D patent details glasses-free display projection


“Apple describes the special display involved as “a projection screen having a predetermined angularly-responsive reflective surface function,” which basically means that the angle of light reflection from different points on the screen would be predicable enough for a computer to bounce light with individual eye accuracy. It’s unclear whether Apple’s system would be able to support more than one simultaneous viewer, or indeed what computational requirements such a setup might demand.

The application was filed back in 2006, and of course there’s no guarantee that Apple ever intends to produce 3D-capable hardware using the technology it covers.”
