There is a new touch screen in town called Displair designed by a Russian inventor, it's a 3D holographic display to replace the traditional screen. It would be used with laptops, TVs and tablets. The amazing thing with this technology is that it uses water mist for the display screen. The Displair projects images onto sheets of water droplets suspended in air, giving the illusion of a hologram. 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.
Displair uses third party computerized 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. To get a feel of how it works, watch the video
