Bridging Book is a special printed book that is placed side-by-side to a tablet device. It brings print and digital publishing together:

Bridging Book is a children’s mixed-media picture-book that blurs the line between printed and electronic books. It consists of a printed book and a digital device, placed side-by-side, with synchronized content. Thumbing through the book’s pages triggers the device to display the complementary digital content. The physical book requires no batteries or wires.
