The "book radio", designed for a class at Ivrea, "takes the mental model of a physical book where user can browse by flipping pages, read by keeping a page open, and create a reminder of a specific page by placing a bookmark. Each page of the "book radio" represents a frequency. The user flips pages to scan the frequency spectrum; opens to a specific page to listen to a station; places the bookmark on a desired page to listen and store the station; and slides the bookmark up or down to control the volume."
