Whereas virtual reality immerses players in a computer-simulated world, augmented reality pulls the digital realm into our world. Marketing firms have approached AR with zeal, leaning on mobile devices to tie coupons and other rewards to physical locations. The game industry has also looked to mobile first when it comes to AR. The Vita game Reality Fighters, for example, pits two brawlers against one another in the real world, while the 3DS' Face Raiders allows you to seek and destroy augmented ships flying around in, say, your bathroom (insert poop joke here).
But projects like Microsoft's IllumiRoom, which uses a projector to overlay a game's environment or particle effects across your living room wall, provide an interesting look at where AR could be headed. Maybe one day we'll be able to convert our living rooms into holodecks. Maybe.
