Navigation methods, systems, and computer program products for virtual three-dimensional books
First Claim
1. A system for displaying images of a virtual three-dimensional document with virtual objects and sections, the system comprising:
- a display system capable of executing a display program,wherein images of the virtual three-dimensional document are produced on the display system, andwherein a scroll bar function for page navigation is provided, the scroll bar function comprising;
computing degree of interest values for sections of the virtual three-dimensional document and assigning degree of interest values to the sections of the virtual three-dimensional document as a function of a currently displayed section of the virtual three-dimensional document;
generating a scroll bar; and
automatically allocating space on the scroll bar based on a the assigned degree of interest function such that portions of the scroll bar are accorded to sections of the virtual three-dimensional document according to the degree of interest of each of the sections, so that greater proportions of the scroll bar are correlated to sections of higher interest.

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. 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.

13. A computer program product comprising:
-
a computer usable medium having computer readable code embodied therein for producing images of a virtual three-dimensional document with virtual objects on a display device, the computer readable code comprising; a scroll bar function for displaying a user-selectable small bar for document navigation, wherein the scroll bar function comprises; computing degree of interest values for sections of the virtual three-dimensional document and assigning degree of interest values to the sections of the virtual three-dimensional document as a function of a currently displayed section of the virtual three-dimensional document; generating a scroll bar; and automatically allocating space on the scroll bar based on the assigned degree of interest function such that portions of the scroll bar are accorded to sections of the virtual three-dimensional document according to the degree of interest of each of the sections, so that greater proportions of the scroll bar are correlated to sections of higher interest. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
