[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.

    So first,

    the technology is dangerous

    but then, it

    can now be touched in complete safety.

    So I conclude they activated the safety protocols.

    That'll end well.

    Doubt it's still safe if one of the beams go into your eyes.

    So a technology that can be touched in complete safety might still be dangerous.
