VIDEO: castAR vs. Google Glass - Fully augmented reality glasses being crowdfunded into reality 10/22/2013 - 00:00 castAR is a projected augmented reality system that displays holographic-like 3D projections right in front of you. 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.
