Touchable holograms shown with ultrasound tech

Touch holograms shown off

University of Tokyo researchers are demonstrating what they call an Airborne Ultrasound Tactile Display (PDF) at the currently ongoing SIGGRAPH event in New Orleans. The prototype uses ultrasound technology to create holograms that can be touched, or at least feel like they're being touched. Because holograms are nothing but light, the team has developed a way to produce tactile feedback. Instead of placing a physical object in the space of where the hologram is created to produce the touch sensation, as this would take away from the quality of the image, the Tokyo University team's solution is to radiate airborne ultrasound that creates pressure field on user's hands.
