TouchWall, a prototype device currently in development by Microsoft Research and Office Labs is a lot like Microsoft Surface, the tabletop computer with multi touch capabilities, except now it hangs from your wall. Some basic uses of TouchWall include dragging, scrolling, enlarging documents as well as viewing photos and videos.

At the CEO Summit, Bill Gates is expected to talk about his ideas on the future of user interface technology and will demonstrate TouchWall and its many practical uses, from giving simple, elegant business presentations to games like Missile Command.
