Abstract
A book for use in an augmented reality system comprises a plurality of leaves, each side forming a page of the book, with each page comprising a fiduciary marker. The book also includes a cover having larger dimensions than the book's leaves. Thus, the cover's extremhities extend beyond the outer edges of the pages. The inside of the cover comprises a first high contrast pattern along at least a first such extremity. An entertainment device for use in the augmented reality system comprises input means to receive a video image of the book, and image processing means to estimate a position and orientation of the book from a fiduciary marker of the book captured in the video image, to estimate a position and orientation of the first high contrast pattern, and to distinguish between one or more leaves of the book being turned independently of the cover of the book.
