Abstract

The present system and method is directed to an interactive navigation system and method for exploring or browsing digital content data that can be spatially structured such that content pages can be located relative to one another. Once a page arrangement layout is completed, a navigation bar in conjunction with an underlying scrolling engine allow fast access to any section of the information space while maintaining an intuitively correct spatial metaphor. Thus, as the user manipulates the navigation bar, the scrolling engine moves the user to the new information content area in a visually intuitive manner while the intermediate content is displayed on a screen.

Claims

1. A computer-implemented method for navigating an information space that includes a plurality of content pages for display on a screen, the content pages being oriented relative to one another in a spatial structure, said method comprising:

displaying a graphical object comprising a plurality of first-level items, each first-level item associated with a respective first-level page and at least one first-level item comprising a plurality of second-level items associated with a plurality of second-level pages, said first and second level items spatially arranged according to the relative orientation of their respective first and second level pages;

selecting a first-level item of said graphical object such that a first-level page associated with said first-level item is displayed on said display screen;

moving from said first-level item to another first-level item of said graphical object such that another first-level page associated with said another first level item is displayed on said display screen and such that said graphical object remains displayed on said display screen; and

displaying other first level pages associated with first-level items located between said first-level item and said another first-level item of said graphical object, between the display of said first level page and said another first level page, thereby providing visual cues as to the movement within the information space.

2. The method according to claim 1, wherein said another first-level page is displayed in response to said another first-level item being selected on said display screen.

3. The method according to claim 1, wherein other first-level items located between said first level item and said another first-level item of said graphical object are viewed while traversed at a predetermined speed during the moving operation.

4. The method according to claim 3, further comprising scrolling on said display screen the respective first-level pages corresponding to said other first-level items during the moving operation.

5. The method according to claim 4, further comprising moving from said another first-level item to a second-level item via said one first-level item such that a second-level page associated with said second-level item is displayed on said display screen.

6. The method according to claim 5, further comprising scrolling on said display screen the respective first-level and second-level pages corresponding to first-level and second level items located between said another first-level item and said second-level item at said predetermined speed during the moving operation.

7. The method according to claim 6, further comprising distinguishing each of the first-level and second-level items on said display screen when traversed during the moving operation.

8. The method according to claim 5, comprising displaying other first and second-level pages associated with said first and second-level items located between said another first-level item and said second-level item of said graphical object.

9. The method according to claim 1, further comprising distinguishing said another first-level item on said display screen.

10. The method according to claim 1, wherein said first-level and second-level pages are arranged in a memory as a two-dimensional matrix, and wherein each of the first-level and second-level pages is identified by an address for calculating an offset between a starting position and an ending position corresponding to said first-level item and said another first-level item, respectively, of said graphical object.

11. The method according to claim 1, further comprising displaying said second-level items as another graphical object if said one first-level item associated with said second-level items is selected for display on said display screen.

12. The method according to claim 11, wherein said graphical object is displayed on said display screen as a first rectangular bar, and wherein said another graphical object is displayed on said display screen as a second rectangular bar differently situated with respect to said first rectangular bar.

13. The method according to claim 1, comprising displaying other first level pages associated with first level items located between said first level item and said another first level item in a sequence relative to the spatial orientation of the content pages.

14. The method according to claim 13, comprising displaying other first level pages associated with first level items located between said first level item and said another first level item at a predetermined speed.

15. A computer-implemented system for navigating an information space that includes a plurality of content pages, the content pages being oriented relative to one another in a spatial structure, said system comprising:

an input device for entering information to said system;

a display screen for displaying the entered information and said plurality of pages; and

a programmable controller causing said display screen to display a graphical object comprising a plurality of first-level items, each first-level item associated with a respective first-level page and at least one first-level item comprising a plurality of second-level items associated with a plurality of second-level pages, said first and second level items spatially arranged according to the relative orientation of their respective first and second level pages, said programmable controller being operative to select a first-level item of said graphical object such that a first-level page associated with said first-level item is displayed on said display screen, said programmable controller being further operative to select another first-level item of said graphical object such that another first-level page associated with said another first-level item is displayed on said display screen, and said programmable controller being further operative to display other first-level pages associated with first-level items located between said first-level item and said another first-level item of said graphical object, between the display of said first level page and said another first level page, while said graphical object remains displayed on said display screen, thereby providing visual cues as to the movement within the information space.

16. The system according to claim 15, wherein said programmable controller is operative to display said other first-level pages associated with first level items located between said first-level and said another first-level item of said graphical object at a predetermined speed.

17. The system according to claim 16, wherein said programmable controller is further operative to cause said display screen to scroll the respective first-level pages corresponding to said other first-level pages corresponding to said other first-level items during the display operation.

18. In a computer-implemented system including an input device, a programmable controller, a display screen and a storage medium for storing program code executable by said programmable controller for navigating an information space that includes a plurality of content pages for display on a display screen, the content pages being oriented relative to one another in a spatial structure, the program code comprising:

first program code means for displaying a graphical object comprising a plurality of first-level items, each first-level item associated with a respective first-level page and at least one first-level item comprising a plurality of second-level items associated with a plurality of second-level pages, said first and second level items spatially arranged according to the relative orientation of their respective first and second level pages;

second program code means for selecting a first-level item of said graphical object such that a first-level page associated with said first-level item is displayed on said display screen;

third program code means for moving from said first-level item to another first-level item of said graphical object such that another first-level page associated with said another first-level item is displayed on said display screen and such that said graphical object remains displayed on said display screen; and

fourth program code means for displaying other first-level pages associated with other first level items located between said first-level item and said another first-level item of said graphical object, between the display of said first level page and said another first level page, thereby providing visual cues as to the movement within the information space.
