Projected Interface

This is an odd idea. Completely bizarre way of displaying content, and I'm not sure how practical this is, especially when compared to the development of Augmented Reality. It might be a lot more use if the projector wasn't hand held- i really cant see any advantage to carry the projector around and have to swing it wildly about in order to see the content. A desk mounted unit, with a much greater projected area would be a lot more practical.
