In an interesting twist on the concept of tactile gaming, TN Games has come out with a "Physical 3D" vest; the 3RD Space FPS Gaming Vest. The idea is that you'd feel events in the game, rather than relying solely on your eyes and ears. The vest uses 8 air-powered "active zones" to generate impact force when it's fed data from your game. "Sense the direction and force of bullet fire, crushing explosions, and fear-inducing finger taps, perfectly synced with the on-screen action," the product page claims.
