They include an amazing "touchable holograph" display developed by a team in Japan. It uses ultrasound device to simulate the sense of touch as the user grasps objects shown in 3D. The other ideas on show are Augmented Reality for Ordinary Toys, Hyper-Realistic Virtual Reality, 3D Teleconferencing and Scratchable Input Devices. If this is the future of computers, sign me up.
