Japan’s Fujitsu Laboratories is bringing touchscreen capabilities to the physical realm with its “FingerLink Interaction System.” The device (a projector and low-res webcam) superimposes an interactive layer on the surface of a book or paper documents, allowing the user to save them as data and then manipulate the object as they would with a touchscreen device. Now that’s power at your fingertips.
