A system is described for displaying images of a virtual three-dimensional book having one or more virtual pages. The system comprises a display system capable of executing a display program wherein images of the virtual three-dimensional book are produced on the display system. A degree of interest (DOI) function is provided for allocating available space on the display system. A page selection function may provide a user-selectable scale along a long axis of the virtual book for selecting virtual pages. Virtual chapter tabs may also be provided for navigating within the virtual book. The display system may also include a page flipping function with several different page flipping speeds and several different page flipping animations for moving between virtual pages in the virtual book. Moreover, a scroll bar function provided to facilitate page navigation wherein space on the scroll bar is allocated using a DOI function. Finally, a computer program product comprising a computer usable medium having computer readable code embodied therein for producing images of a virtual three-dimensional book is also disclosed.

Navigation methods, systems, and computer program products for virtual three-dimensional books

A system is described for displaying images of a virtual three-dimensional book having a plurality of virtual pages. The system comprises a display system capable of executing a display program wherein images of the virtual three-dimensional book are produced on the display system. Information relating to the virtual three-dimensional book may be displayed on an edge of the virtual three-dimensional book. This information may comprise a table image, meta-data about references in the book, information about the organizational structure of the book, or graphical data. Additionally, several columns or rows of information may be displayed on the virtual book edge, each column or row being selectively expandable and contractible. Moreover, a virtual three-dimensional book may be displayed in a way that bears a metaphorical relationship to the contents of the virtual three-dimensional book. Also disclosed is a computer program product comprising a computer usable medium having computer readable code embodied therein for producing images of a virtual three-dimensional book.

Methods, systems, and computer program products for display of information relating to a virtual three-dimensional book

A system is described for displaying images of a virtual three-dimensional book having one or more virtual pages. The system comprises a display system capable of executing a display program wherein images of the virtual three-dimensional book are produced on the display system. The display system may include a magnification function producing a virtual magnifier moveable over the virtual pages. The display system may also include a the 'stretchy page' display method wherein one section of the page is directly magnified, while other adjacent sections may be directly magnified in a horizontal or vertical direction, but not both directions. Moreover, a virtual page may also be tilted about a central axis of the virtual page to accommodate viewing of a desired section on the display system. Finally, a computer program product comprising a computer usable medium having computer readable code embodied therein for producing images of a virtual three-dimensional book is also disclosed.
