Realizing that the oft-promised 'paperless office' may never actually come to fruition, researchers at Fujitsu are working on a backup plan that gives printed documents similar tablet-like touchscreen functionality.

Using a tabletop projector, webcam, and other sensors, the system can precisely detect finger movements and motion in 3D, allowing a user to interact with a printed page and digitize text or pictures by simply tapping or dragging out selection boxes. The projector creates UI elements that are perfectly matched to a user's finger motions, but it can also facilitate additional content like animations or videos on the page. One thing's for certain, staying up all night to cram for a college final would be a heck of a lot easier with an enhanced textbook. [DigInfo TV]
