A Physics Rebel Shakes Up the Video Game World, Literally is an article about Kor-fx, an "acousto-haptic" device from startup Immerz to be released for PC gamers next year and console gamers sometime after that (thanks Slashdot). Of course it isn't actually a force-feedback bra, but it does involve a pair of transducers draped over the player's chest to create an enhanced sense of immersion by vibrating with the sounds of a game or movie. The article also has some background on the device's inventor, Shahriar Afshar, an Iranian-American physicist-turned-entrepreneur known in science circles for a controversial conclusion that refutes Niels Bohr's interpretation of wave-particle duality. Back to the Kor-fx device, here's a bit from the article explaining how this operates:

Because the transducers vibrate in stereo, and because the human tactile system is pretty good at translating vibrations into directional information, it’s actually possible for someone wearing the device to sense which direction gunshots are coming from in a first-person-shooter game like Half Life, and even to feel events occurring “behind” them in the virtual world. Afshar calls this the “seventh sense.” (I’m not just repeating public-relations verbiage here—I’m one of the first journalists who has had a chance to try out the device, which adds an almost frightening level of you-are-there realism to both video games and action movies.)
