There’s real reality and virtual reality, but then there's augmented reality where the real and the virtual are blended together. Metaio is using this technology to help companies build and repair cars and even sell them, with a series of interactive advertisements from Mini Cooper that use a Web cam to turn a magazine page into a 3D animated model of a car. But, it isn't just for cars. Curious just how that chair will fit in your room? Metaio has an iPhone application that will do just that.
