There are two patents in total, the first is for a “Media Enhanced Pop-up Book” and this one will make use of a smartphone or tablet to aid in the process by interacting with the use of the book. So for instance, as you turn a page, the phone or tablet understands and responds accordingly. The second patent is the far more interesting one, as this one essentially forgoes the use of a smartphone and tablet and instead employs a small device which has been likened (in appearance) to a hamburger. The device is placed in the middle of the book and then embedded sensors on the pages allow for a more interactive reading experience. The hamburger will essentially be able to interact with the reader’s pressure or motion and change the imagery displayed on the pages.
