Developed by Mitsubishi Electric Research Laboratories (MERL), this interactive multi-input panel allows users to control such games as Warcraft III with “an array of antennas embedded in the touch surface”. Basically, a receiver connected to each user’s chair, gets signals from antennas near the touch point. The displays are available in 32-inch and 42-inch sizes. Video clip after the jump.
From the article: “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.”
