Researchers Developing Touchable Holograms
A group of researchers at the University of Tokyo's Department of Complexity Science and Engineering have been working on a prototype of holograms that you can touch called Haptoclone. The device allows you to send a holographic image of say, a ball, to another person who can then also interact with the object.
Explains Digital Buzz Blog, "Each HaptoClone has four high-end ultrasound arrays that deliver ultrasonic radiation pressure to allow you to feel the Hologram object. While Microsoft Kinect maps the object in real-time and so that the ultrasound arrays in the other device deliver the correct 'feeling' that you’d expect based on its position."
