Kamanin was keen to invent something that would allow people to display and interact with information without cluttering the physical environment and so he created the whole concept of projecting 3D images onto sheets of mist, giving the illusion of a hologram.
The researchers explained that an airstream is created from tiny water drops, similar to the ones in the clouds. The water drops are so tiny they don't have any moisture in them; one can test it on paper or your glasses- the piece of paper remains dry and the glasses don't steam up. One can then see images that are projected onto these tiny water drops.
Users of Displair need not wear special glasses as with many other new screen systems. This is because the image is being displayed onto an invisible screen, which responds "intuitively" to hand movements.
Displair is one of the simpler concepts in the burgeoning holographic and 3D projection industry.
