Researchers show virtual smartphone projection
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.
The nature of the projection still lets it display videos and live interaction. User would also be free to apply live effects filters to some or all of the image. By its nature, users can freely rotate images sideways or otherwise adjust the image in a way that isn't practical with optical projection.
As a research project, there's no clear indication of if or when devices could start using the technique. It would need software support on mobile devices and, since it would need a second display and not just a screen, could be more expensive. Baur, Boring, and Feiner imagine it being useful for those who already have displays on hand, however, and picture all smartphones having the option at some point in the future. [via Engadget]

Huh?
Ok I don't get it. What's the point of "projecting" an image onto a screen in this way? So we can simulate jiggle and awkward positioning? I can see that this is an impressive technical achievement, but I can't imagine why they invested the time and energy into solving this imaginary problem.
And what on Earth is a "frustum?"
