Holoportation is telepresence with a twist. You capture and playback objects and people in 3D. If you manage to do this in real-time you achieve holographic telepresence and you are that much closer to Star Wars-like holo-communicators. This particular video is a demonstration of what Microsoft Research currently works on.
Check out more information about this project on their website. Some of the images seem to be manipulated though in order to translate the immersion of the person who is actually using the viewing device. Nevertheless, we got the idea and it looks intriguing!
