Realising 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 digitise 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 that university exam would be a heck of a lot easier with an enhanced textbook. [DigInfo TV]
