Abstract

A method and apparatus for browsing through a computer database on a computer system with a graphical user interface. The information to be browsed is displayed on a display screen. A browsing tool which resembles a magnifying glass is displayed on the display screen on top of the information. The browsing tool has a viewing lens with targeting crosshair and a "magnifying" reticle. When the browsing tool is moved about the screen, the information on the screen is shown in normal form. When the browsing tool comes to a rest, the information within the viewing lens of the browsing tool is modified depending on the current browsing tool mode. When the browsing tool is in magnification mode, the information within magnifying reticle is enhanced such that it fills the entire viewing lens of the browsing tool. When the browsing tool is in hierarchical browsing mode, the next lower level of the hierarchy is displayed within the viewing lens of the browsing tool. When the browsing tool is in data filtering mode, the information is displayed according to a preset filtering rule.

5. The apparatus for browsing as claimed in claim 4 wherein said moveable browsing tool resembles a magnifying glass.

6. The apparatus for browsing as claimed in claim 5 wherein the viewing area of said moveable browsing tool is translucent.

7. The apparatus for browsing as claimed in claim 1 wherein said database stores said data in a hierarchical format, said hierarchical format comprising successively deeper hierarchical levels of data, and said enhancement means comprises

means for fetching a next deeper hierarchical level of the data in said viewing area;

and

means for displaying a graphic representation of said next deeper hierarchical level of data in said viewing area.

8. The apparatus for browsing as claimed in claim 1 wherein said enhancement means comprises

means for setting a data filtering rule;

means for applying said data filtering rule to the data in said viewing area to generate a set of filtered data; and

means for displaying said a graphic representation of the set of filtered data in said viewing area.

9. The apparatus as claimed in claim 1 wherein said magnification area is adjustable with respect to said viewing area, said adjustable magnification area capable of targeting specific areas of said graphic representation of data within said viewing area to be enhanced by said enhancement means.

10. The apparatus as claimed in claim 9 wherein said adjustable magnification area has a proportional size relationship with respect to a degree of enhancement of said targeted areas of said graphic representation of data within said adjustable magnification area.

11. A method of browsing information stored in a computer database on a computer system with a graphics display screen, said method comprising the steps of:

displaying said information from said computer database on said graphics display screen;

rendering a moveable browsing tool having a viewing area with a magnification area disposed therein on said graphics display screen over said information from said computer database;

positioning said moveable browsing tool on said graphics display screen in response to input signals from an operator, said information from said computer database visible in said viewing area allowing said operator to selectively target a portion of said information with said magnification area; and

enhancing said information within said magnification area immediately after said operator ceases positioning said moveable browsing tool for a predetermined amount of time and displaying an enhanced image of said information in said viewing area of said moveable browsing tool.

12. The method of browsing information stored in a computer database as claimed in claim 11 wherein said step of positioning said browsing tool on said graphics display screen further comprises:

receiving input signals from a cursor control device;

rendering a cursor on said graphics display screen, said cursor positioned on said graphics display screen in response to said input signals from said cursor control device, said cursor used for selecting and positioning said moveable browsing tool on said graphics display screen.

13. The method of browsing information stored in a computer database as claimed in claim 12 wherein said cursor control device comprises a computer mouse.

14. The method of browsing information stored in a computer database as claimed in claim 11 wherein said step of rendering a moveable browsing tool further comprises drawing a magnifying reticle within viewing area of said moveable browsing tool defining said magnification area and wherein said step of enhancing said information within said magnification area further comprises rendering an enlarged image of the information within said magnifying reticle in said viewing area.

15. The method of browsing information stored in a computer database as claimed in claim 11 wherein said database stores said information in a hierarchical format said hierarchical format comprising successively deeper hierarchical levels of data, and said step of enhancing said information within said viewing area further comprises

fetching a next hierarchical level of the information in said viewing area;
