Could touch display projected on mist replace physical screens?

According to Russian designer Max Kamanin, creator of Displair, high-tech displays made from mist and air are "the next step in visual technology".

His solution? Projecting 3D images onto sheets of mist, giving the illusion of a hologram:
An airstream is created from tiny water drops, similar to the ones in the clouds.

With Displair, users need not wear special glasses

Screen responds 'intuitively' to hand movements

According to Displair the image is created inside a layer of "dry fog which is composed of ultra-fine water droplets."

3-dimensional projections are created using infrared sensors.

The screen responds "intuitively" to hand movements -- 1500 of them -- many of which are similar to those used on our mobile devices, such as pinch-and-zoom.

The screen's inventors think that Displair screens could be used in medicine, and offer a more hygienic alternative to touchscreens.

In the future the team hope to explore scent, to offer users a multi-sensory experience.
