New reality: Invisible 3D holograms that can be touched and felt

Immersive, highly visual, 3D environments are now on the horizon after British scientists managed to recreate mid-air sensory experiences by controlling sound waves to project 3-D haptic holograms that can be seen and felt.

A team from the University of Bristol’s Interaction and Graphics research group, using the UltraHaptics, a system for creating haptic feedback in mid-air, were successful in testing several shapes, including spheres and pyramids .... http://rt.com
