The promise of castAR is a holographic display system, inspired (as all good ideas are) by science fiction:
Star Wars: Episode IV – A New Hope sparked our imaginations of what might be possible in the future by showing R2-D2 and Chewbacca playing a holographic 3D chess-style game. It has taken nearly 35 years since the film was released for this technological dream to come to reality, but with castAR, that reality can be yours.
The system consists of two components: a pair of glasses and a surface. The glasses have a pair of micro projectors that provide a view of a 3D image on the surface, and your eyes focus on this just as if it were sitting on the surface.
castAR is some amazing tech and if you care to, you can get in on the bleeding edge by supporting their Kickstarter campaign.
