Friday morning video — Touchable Holograms

By Chris McDowall 08/10/2010

My jaw dropped when I saw this video of researchers at Tokyo University creating holographic images that “feel” like physical objects. The technology uses ultrasonic waves to create a sensation of pressure on the hands of people interacting with the hologram. When inaudible sound waves emitted by a set of ultrasonic transducers interfere, they can create a focal point that is perceived as a solid object.

It’s a clever idea that brings us one step closer to building a holodeck. (via O’Reilly radar and BBC news)
