if:book reports that Manolis Kelaidis made a big splash at the O’Reilly Tools of Change for Publishing conference with his networked paper book.
Here’s a an excerpt from the posting:
Manolis Kelaidis, a designer at the Royal College of Art in London, has found a way to make printed pages digitally interactive. His "blueBook" prototype is a paper book with circuits embedded in each page and with text printed with conductive ink. When you touch a "linked" word on the page and your finger completes a circuit, sending a signal to a processor in the back cover which communicates by Bluetooth with a nearby computer, bringing up information on the screen.
Here’s an excerpt from a jusTaText posting about the demo:
Yes, he had a printed and bound book which communicated with his laptop. He simply touched the page, and the laptop reacted. It brought up pictures of the Mona Lisa. It translated Chinese. It played a piece of music. Kelaidis suggested that a library of such books might cross-refer, i.e. touching a section in one book might change the colors of the spines of related books on your shelves. Imagine.
