__NOTOC__
Displair is a 3D interactive raster display technology developed by a Russian company of the same name. The Displair projects images onto sheets of water droplets suspended in air, giving the illusion of a

. Unlike other cold fog projecting technologies, the images projected by the Displair can also respond rapidly to multi-touch manipulation, as well as allowing taste and aroma to be incorporated.
History
Developer Maxim Kamanin introduced the Displair at Seliger 2010. In July of that year he chose the "Displair" name for both the product and the company as aportmanteau

Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, cal ...
method. These particles are small enough not to leave traces of moisture, and their surface tension high enough to maintain stability after contact with physical objects and wind.
Displair uses third party computerised multi-touch technologies to allow control of images with fingers or with other objects. The display can work with up to 1500 touch points simultaneously with a delay time of less than 0.2 seconds. This makes it possible to allow manipulation by more than one user, and also to identify more complex gestures than similar 3D display systems. The company is working on incorporating flavoring and taste interaction with projected images in the future.
