The Tactile Gaming Vest (TGV) doesn't just react when you get shelled in a game. It transmits a different sensation depending on the kind of hit you take. Talk about augmented reality.
The TGV is a haptic feedback device that uses solenoids, eccentric-mass motors, and Peltier elements—all controlled by custom electronics and a personal computer—to give users the ultimate immersive experience:
When the player's character experiences injury in the game, the vest simulates the appropriate sensation (bullet hit, vibration, and/or heat) in the correct location on the player's body.
It's not the first feedback gaming vest, but it's the first I've seen that distinguishes between a gun shot, a slash, and a pewpew. The grad students who developed it did so by expanding on this product from TN Games. The TGV's still in the development stages, with some kinks to be worked out, but the potential for both gaming and movie-going is pretty incredible.
