The Book Radio, designed by Vinay Venkatraman with Pei Yu at the Interaction Design Institute Ivrea, sits nicely beside other book-shaped products: Scan radio channels by flipping the pages, book mark radio stations and also annotate favorite programs by actually writing on to the relevant pages; change the volume by sliding the bookmark in or out.

And how does it work?
Technically speaking the book has embedded sensors and a powerful micro-controller (a miniature computer) in the spine. The embedded software can detect the page position by measuring the density of paper and scans a digital radio. The book then wirelessly talks to a base unit with speakers. Alternatively it can be used with headphones just like a personal music player.
