[citation][nom]dreadlokz[/nom]that "gun controller" would only make sence on a sphere screen room, and with integrated kinnect or something even better ;p Also it would kill the game adiction, since it would be impossible to play more them 2 hours/day if ur not the athletic type! haha[/citation]
no... lets think bare minimum
it would require 1, possibly 2 kinect like devices, maybe even just a web cam, and 4 different colored light vest. it the vest would be cheaper and could tell what direction toy are facing
it would require a brain, think of it like that cellphone demom a while back where the phone would plug into a tablet and a laptop shell and use the keys and and screen they had, but all the real power was in the phone, get that make it small and make it so it can plug into a gun device, all it would need is a gyroscope, compass and possibly an acceleromiter and transmitter, ill estimate cost at about 10$-15$, and it would need a gun which a cheap shell, plastic and no blow back about 10$ at most, with blow back and realistic weight about 30, and with a full metal real as it gets with out being real, about 50-100$
you would need a head mount display, but that is a cost you can write off as a monitor/tv it will be good for years and not need an upgrade for at least 5 years.
in the head mount, you would need another brain device.
and it wouldn't kill game addiction, oh no, FER from it, i know enough people that if you had a fighting game where it was real swordplay, and it worked just like real life 99% of the time, they would get in shape to play it.
hell i would be more fit than an olympic athlete if a game i loved playing required it from me, but sadly, we have the waggle fest wii, the dance crap of the kinect, and the only one that had promise of being great, the move, never even took off.
