Boffins at the University of Tokyo have developed 3D holograms that can be touched with bare hands Dubbed the Airborne Ultrasound Tactile Display, the hologram projector uses an ultrasound quirk called acoustic radiation pressure to create a pressure sensation on a user's hands. This information is tracked with two Nintendo Wiimotes. It means that the user doesn't use any direct contact and so doesn't dilute the quality of the hologram.
