DiamondTouch is fully-multiuser, and multi-input. It is somewhat similar to NYU’s Multi-Touch Interface.

According to Mitsubishi Electric Research Laboratories:

“DiamondTouch is front-projected and uses an array of antennas embedded in the touch surface. Each antenna transmits a unique signal. Each user has a separate receiver, connected to the user capacitively, typically through the user’s chair. When a user touches the surface, antennas near the touch point couple an extremely small amount of signal through the user’s body and to the receiver. This unique touch technology supports multiple touches by a single user (e.g., two handed touch gestures) and distinguishes between simultaneous inputs from multiple users. DiamondTouch tables are available in two sizes (32″ diagonal and 42″ diagonal display), while custom sizes and shapes are available on spec.”

Mitsubishi’s system also includes voice control, and they show it all off with demos of WarCraft III and Google Earth.
