Live Book: A mixed reality book using a projection system

In this paper, we propose a mixed reality book service, called Live Book, which provides new user experience by directly augmenting digital contents on a printed book using a small projector. For this service, a stand-type system was developed, which recognizes each page of the printed book and then automatically projects digital contents corresponding to that page. Main feature of the Live Book is its ability to allow user to interact with the system using a bare finger.
