Bath-water video game touchscreen makes a splash

Researchers at Tokyo's University of Electro-Communications have made a bath-water touchscreen.

Click's LJ Rich visited the Koike Laboratory for a "hands-in" experience.

The Aquatop Display projects an image onto a water-filled bath. Users dip their hands in to control a computer game.

Hand movements are detected by a Microsoft Kinect camera. The data collected is then translated into instructions that control the game.

The fountains are driven by playing a low sound through waterproofed speakers at the bottom of the bath. Users can interact with the display from above or below the water's surface.
