From the BBC:

Any paper document can be turned into an interactive touchscreen using a projection and camera system developed by Fujitsu.

The system lets users instantly copy text and photographs by using a finger to draw a box around them.

The digital copies can then be moved, edited and manipulated as if they were on a tablet or large touchscreen.

Fujitsu said it hoped to release a commercial version of the imaging technology in 2014.
