Microsoft Research has released a video that shows Star Wars-like holographic using a technology called "Vermeer."
"Vermeer is a novel interactive 360° viewable display suitable for a tabletop form factor from Microsoft Research Cambridge. It provides viewpoint corrected stereoscopic 3D graphics to simultaneous users 360° around the display, without the need for eyewear or other user instrumentation," Microsoft stated.
In contrast to other systems, Vermeer "allows users for the first time, to reach into and directly touch 3D objects inside a display volume. It also enables simultaneous users 360° viewing of the 3D object. Inherently other 360° systems restrict interactions to outside the display volume behind a protective glass or plastic dome."
