A book for use in an augmented reality system comprises a plurality of stiff leaves, each side of which forms a page of the book and in which each such page comprises a fiduciary marker, and a cover having larger dimensions than said leaves of the book, and hence having extremities that extend beyond the outer edges of said pages, in which the inside of the cover comprises a first high contrast pattern along at least a first such extremity; meanwhile, an entertainment device for use in the augmented reality system comprises input means operable to receive a video image of the book according, and image processing means operable to estimate a position and orientation of the book from a fiduciary marker of the book captured in the video image and operable to estimate a position and orientation of a first high contrast pattern on an extremity of an inside cover of the book captured in the video image, and in which the image processing means is operable to distinguish between one or more leaves of the book being turned independently of the cover of the book, as opposed to the turning of a cover of the book, in response to the position and orientation of the first high contrast pattern. |
