Researcher trio Dominikus Baur, Sebastian Boring, and Steve Feiner have put forward a paper showing how virtual projection could be a staple feature of smartphones and tablets in the future. Using iPhones as testbeds, the technique would send a rapid-fire series of screenshots to a desktop display or TV using the rear camera to provide a frame of reference for where the image appears. It not only wouldn't need the exact positioning of a real projector but could be resized at will or support multiple projections, either from multiple devices or just one.
