Scientists from the University of Tokyo have created what they’re calling an Airborne Ultrasound Tactile Display, that’s basically a touchable holographic 3D display. Integrating a concave mirror onto which an LCD projector creates the image part of the system, together with an acoustic radiation pressure generator, the display can generate the feel of coming into physical contact with projected 3D objects as the user moves their hand around.
