Abstract

A method for navigating a pointer on a graphical user interface (GUI) includes the steps of: scrolling an input device to locate the pointer corresponding to the input device on a point of interest within the GUI, depressing an actuating button associated with the input device on the point of interest, obtaining a detailed view of the point of interest while centering the point of interest on the GUI and maintaining a position of the pointer on the point of interest.

Claims

1. A computer readable medium containing executable instructions which, when executed in a processing system, cause the system to perform a method comprising:

moving a cursor from a first display point on a user interface to a second display point on said user interface, said second display point being away from a center of said user interface;

receiving a selection input associated with said second display point;

providing a detailed view of the second display point and centering the user interface around the second display point; and

maintaining a position of the cursor on the second display point,

wherein the detailed view is obtained in a series of intermediate zooming levels,

further comprising storing information for each of said intermediate zooming levels as a history.

2. The computer readable medium of claim 1, wherein the detailed view of the second display point is obtained while zooming in on the second display point and simultaneously panning over the user interface.

3. The computer readable medium of claim 1, wherein the cursor position is maintained over the second display point at each zooming level.

4. The computer readable medium of claim 1, wherein the number of zooming levels is at least two.

5. The computer readable medium of claim 1, further comprising:

computing a linear distance between the center of the user interface and the second display point;

drawing a virtual line representing the linear distance; and

animating a movement of the cursor along the virtual line in said series of intermediate zooming levels.

6. The computer readable medium of claim 1, wherein the user interface corresponds to a location information program.

7. The computer readable medium of claim 1, wherein the user interface corresponds to a menu selection in a pay per view environment.

8. A method for handling a cursor on a user interface, comprising the steps of:

moving a cursor from a first display point on a user interface to a second display point on said user interface, said second display point being away from a center of said user interface;

receiving a selection input associated with said second display point;

providing a detailed view of the second display point and centering the user interface around the second display point; and

maintaining a position of the cursor on the second display point,

wherein the detailed view is obtained in a series of intermediate zooming levels, further comprising storing information for each of said intermediate zooming levels as a history.

9. The method of claim 8, wherein the detailed view of the second display point is obtained while zooming in on the second display point and simultaneously panning over the user interface.

10. The method of claim 8, wherein the cursor position is maintained over the second display point at each zooming level.

11. The method of claim 8, wherein the number of zooming levels is at least two.

12. The method of claim 8, further comprising:

computing a linear distance between the center of the user interface and the second display point;

drawing a virtual line representing the linear distance; and

animating a movement of the cursor along the virtual line in said series of intermediate zooming levels.

13. The method of claim 8, wherein the user interface corresponds to a location information program.

14. The method of claim 8, wherein the user interface corresponds to a menu selection in a pay per view environment.
