Russian company Displair showed off their eponymous device, which has the ability to project a touchscreen onto water vapor, at this year's Consumer Electronics Show.
The Displair works by attaching a mobile device to a projector, which then emits an image onto a vertical wall of water vapor. Using a built in camera, it can then track player moves, transofrming the mist into one big touchscreen. A single unit currently runs at about $10,000, although more consumer-friendly models are expected sometime in the next five years.
