ABSTRACT:
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.
