Scientists create holograms you can touch

Holograms may be about to get more practical and useful. Scientists have invented a way of creating holograms that can be touched and manipulated.

Researchers in Japan have created touchable holograms by inventing a new laser technology called "Fairy Lights."

By firing laser pulses that last just one millionth of one billionth of a second in succession at a high frequency, they appear like a constant beam. This hologram can then be touched and manipulated with its shape responding to touch.

The touchable holograms are currently quite small, but it’s a start. Scientists at Utsunomiya University Center for Optical Research and Education believe that their work is scalable.

Lead researcher Yoichi Ochiai told Ignition magazine that he envisions that this technology could be used “in situations where three-dimensional communication is necessary such as a construction site or in the medical field.”

Fairy Lights could also be used for holographic keyboards, similar to the virtual keyboard from Brookstone pictured, or for gaming purposes.
