Bringing Holograms to Videoconferencing
Videoconferencing is kind of cool. The ability to actually see the person you are talking to allows you to pick up on nonverbal cues and, for some people, is more comfortable than talking to a disembodied voice. Still, talking to a flat screen is not the same as talking to someone standing in the room, so researchers at Queen's University have created a cylindrical display system for projecting 3D holograms.
By using a 3D projector, acrylic cylinder, a convex mirror, and some Kinects, the researchers built the TeleHuman and BodiPod systems. TeleHuman is a videoconferencing system that creates a 3D image a person can walk around. If for some reason you want to see the other person’s back, just walk around the cylinder and see. The BodiPod system is for the display and manipulation of 3D human anatomy model. With gesture controls a user can peel away layers to the body while voice commands can be used to zoom in on specific organs.
