We are introducing a new type of digitally enhanced book which symbiotically merges different type of media in a seamless approach. By keeping the traditional book (and its affordance) and enhancing it visually and aurally, we provide a highly efficient combination of the physical and digital world. Our solution utilizes recent developments in computer vision tracking, advanced GPU technology and spatial sound rendering. The systems' collaboration capabilities also allow other users to be part of the story. Keywords Interactive Book, Augmented Reality, Mediated Reality. ACM Classification Keywords H5.2. User Interface
