[translation mine] The holographic technology Aerial 3D, based on using laser-induced plasma, enables modifying air molecules to give the appearance of brilliant points of light, and thus creating pixels in suspension. However, the technology is dangerous because it can burn the skin.

Japanese researchers at the University of Tsukuba have augmented the speed of their lasers to create holograms, still based on plasma, but which can now be touched in complete safety.

In order to heat air molecules to make a pixel of light appear, the researchers fire ultra-short laser bursts on the order of femtoseconds (a millionth of a billionth of a second).

The ultra-short bursts cannot damage the skin. The holograms drawn in the air react in real time to touch and generate haptic feedback. For example, one can break the hologram with a touch and feel the shockwaves generated by plasma, as though the light had physical substance.

Disney imagineer Ivan Poupyrev presented a technique at Makers Faire a couple years ago that used directed puffs of air (vortices) to create haptic feedback.

    Much like the term hacker was misused then completely destroyed, so will the term holography.

    This looks more like a step in the right direction as far as the "holodeck" hologram is concerned as opposed to your random pessimism.

      Its not random at all, its quite targeted to the misuse and perversion of yet another term due to the public's stupidity.

        Well, we have windows 10 at least. No one has seen to it to sully the name of Windows with a ridiculous use of the word as applied to a popular misconception. For that, we have Chrome!
