Projection in the air
The FogScreen is a new invention which makes objects seem to appear and move in thin air. It is a screen you can walk through. The FogScreen is created by using a suspended fog generating device, there is no frame around the screen. The installation is easy: just replace the conventional screen with FogScreen. You don't need to change anything else - it works with standard video projectors.With a new interactive add-on you can also use the air as your user interface. Operate computers by touching only the air with your bare hand.
