Here’s a first: a book with built-in radio capabilities, in which users turn the pages to change stations and slide a bookmark in/out for adjusting the volume. Plus, the device is wireless and allows you to bookmark radio stations for later listening. This nifty gadget was designed by Vinay Venkatraman and Pei Yu. Pricing and availability have not yet been announced.
It works by detecting the density of paper, and then wirelessly communicating the resulting frequency to the base unit, which then broadcasts the signal via speakers or headphones.
