Touchable hologram revealed at Siggraph

At this year’s Siggraph, the international exhibition for computer graphics and interactive techniques, a team of R&D boffins from the University of Tokyo demoed a piece of technology called Airborne Ultrasound Tactile Display.

The technology uses ultrasound to enable a hologram to move around as and when a person touches it, creating what’s called a touchable holography.

What’s more striking is that you can feel the touch sensation from the acoustic radiation pressure coming out of the ultrasound, bringing interaction between human and technology even closer.
