Abstract
A system for enhancement of books or other reading material includes an item of reading material, printed on a substrate having a substantially invisible, machine-readable coordinate grid. A pointing device is configured to detect the coordinate grid on the substrate when placed in proximity thereto. An output device receives input from the pointing device to determine the location of the pointing device relative to the substrate, and provides output corresponding to contents of the reading material at the location. The output may be in the form of audio and/or video.
