Microsoft has already unveiled mega-expensive “Surface” computers, with which a user interacts solely through touch. Now, cNet reports, it's unveiled an impressive lower-budget version: the TouchWall. Touchwall looks like an ordinary projector, except that the image it projects on the wall is itself an interactive touch screen.
Bill Gates showed off the TouchWall to a group of CEOs at Microsoft headquarters, emphasizing the eventual economy of the technology, which could have widespread applications in education and business presentations. "We're saying it will be absolutely pervasive," Gates said of the TouchWall surface. "When I say everywhere, I mean the individual's office, the home, the living room."
