Fogscreen technology which allows systems to project images into whats seem to be thin air has been around for sometime. But a new system deigned by Russian company DisplAir has now been created which allows you to make those images interactive.

DisplAir uses an infrared camera to capture finger gestures, which are used to control the images that are projected into a stream of cold fog. Watch the video after the jump to see it in action.

DisplAir says it is capable of creating systems with 40 to 140-inch screens. Explaining that when the technology goes main stream and can be manufactured in large quantities, the device may cost between $4000 and $30,000. DisplAir hopes to sell their new technology to the advertising and entertainment industry.
