ith its game-activated internal pneumatic pockets, the FPS has no interest in hugging you, but it will gladly simulate a gunshot to your torso. A surgeon, who was trying to develop a system for remotely diagnosing prisoners, designed the FPS Vest. It has four pockets in the front, four in the back, and connects to a small USB-powered air compressor. Different pockets will activate to varying degrees, depending on what’s happening to you in the game. The FPS can apparently simulate hits from a pistol or an Uzi, along with the sensations of explosions, stabbings, rocket hits, and falling (one would assume they actually mean “landing”.) Presumably, being shot in real life feels a little worse than being thumped by an air pocket, but you get the idea. To use the vest, you just put it on, plug it into the USB port of your PC, Xbox, PlayStation or Wii, and get ready for the hits. Its driver supports more than 40 first-person shooter games, including the Call of Duty and Halflife franchises.
