Abstract

A method and apparatus for intelligent scrolling. In a computer system that has a user interface which allows for the movement of items from a first open window to a second open window or to a second region, such as a desktop, the present invention allows a user to select one or more items in the first window, move the selected item(s) to within a predetermined distance from an edge of the first window for a predetermined period of time and cause the viewable portion of the data and/or document within the first window to scroll in a corresponding direction.

Claims

1. In a computer controlled display system having a display wherein a plurality of regions may be displayed including at least a first region, said first region having at least a first item within a visible display area of said first region and said first region having at least one item, including a second item, which is not within the visible display area of said first region, a method for scrolling the contents of said first region to display said second item comprising:

selecting at least said first item within said first region by positioning a cursor over said first item and by placing a switch means in a predetermined position so that said first item is associated with said cursor for further operation or manipulation;

positioning said cursor over a predetermined scrolling area;

determining that a predetermined period of time has elapsed while the cursor has been positioned in said predetermined scrolling area; and

scrolling the contents of said first region in a direction corresponding to said predetermined scrolling area to display said second item while said first item remains selected and associated with said cursor.

2. A method as in claim 1 wherein said step of positioning said cursor over said predetermined scrolling area occurs while said switch means is kept in said predetermined position.

3. A method as in claim 2 wherein said first region comprises a window and wherein a second region comprises a desktop which cannot be scrolled.

4. A method as in claim 3 wherein said switch means is located on a cursor control device which positions said cursor on said display and said first region contains at least four predetermined scrolling areas comprising a scrolling area located near the tip edge of said first region, a scrolling area near the bottom edge of said first region, a scrolling area near the left edge of said first region, and a scrolling area near the right edge of said first region.

5. The method recited in claim 1 wherein said step of scrolling the contents of said first region further includes scrolling said first region at a rate corresponding to the position of said cursor in said predetermined scrolling area.

6. The method as recited in claim 5 wherein said scrolling direction is a diagonal direction.

7. The method as recited in claim 1 is further comprised of the steps of:

positioning said cursor over a second predetermined scrolling area; and

scrolling the contents of said first region in a direction corresponding to said second predetermined scrolling area.

8. A method as in claim 1 wherein said step of determining that a predetermining period of time has elapsed also determines whether scrolling is in a first and or a second context and wherein said predetermined scrolling area causes scrolling in a first direction in said first context and causes scrolling in a second direction in said second context.

9. A method as in claim 8 wherein said first direction is perpendicular to said second direction.

10. In a computer controlled display system having a display wherein a plurality of windows may be displayed, each of said plurality of windows being capable of displaying a plurality of items, said computer controlled display system allowing at least one selected item from a first window of said plurality of windows to be moved to a second of said plurality of windows, a method for scrolling a visible display area of said first window comprising the steps of:

positioning a cursor on a first item in said first window by manipulation of a cursor control device;

selecting said first item so that said first item is associated with said cursor for further operation or manipulation;

positioning said cursor in one of a plurality of predetermined scrolling areas associated with said first window;

determining that a predetermined period of time has elapsed while the cursor has been positioned in said predetermined scrolling area and while said first item remains selected; and

scrolling said visible display area in a corresponding direction of said predetermined scrolling area, said corresponding direction determined by the location of said predetermined scrolling area relative to said first window while said first item remains associated with said cursor.

11. A method as in claim 10 wherein said step of selecting said item is further comprised of placing a switch means associated with said cursor control device in a predetermined position.

12. A method as in claim 11 further comprising the steps of:

determining said switch associated with said cursor control device is not in said predetermined position; and

terminate scrolling of said visible display area.

13. A method as in claim 12 further comprising the steps of:

determining that the cursor is no longer positioned in said predetermined scrolling area; and

terminate scrolling of said visible display area.

14. A method as in claim 13 wherein said predetermined period of time has elapsed while the cursor has been positioned in said predetermined scrolling area is one-sixth of a second.

15. A method as in claim 14 wherein a rate of scrolling is dependant on cursor position with respect to an outside edge of said predetermined scrolling areas, so that when said cursor is positioned closer to an outside edge of said predetermined scrolling areas, said scrolling rate is increased.

16. A method as in claim 15 wherein said cursor may be simultaneously positioned in more than one of said predetermined scrolling areas, so that scrolling is in two directions.

17. A method as in claim 10 wherein said first item is selected by positioning said cursor over said first item and by placing a switch means in a predetermined position and wherein the step of positioning said cursor in one of a plurality of predetermined scrolling areas occurs by moving a representation of said first item, while keeping said switch means in a predetermined position, over to said one of a plurality of predetermined scrolling areas.

18. In a computer controlled display system having a display wherein a plurality of regions may be displayed including at least a first region, said first region having at least one item, including a first item, within a visible display area of said first region and said first region having at least one item, including a second item, which is not within the visible display area, said second item being a directory, a method for scrolling the contents of said first region to display said second item and depositing at least said first item into said second item, comprising:

selecting at least said first item within said first region by positioning a cursor over said first item and by placing a switch means in a first predetermined position;

positioning said cursor over a predetermined scrolling area located within said first region;

determining that a predetermined period of time has elapsed while the cursor has been positioned in said predetermined scrolling area;

scrolling the contents of said first region in a direction corresponding to said predetermined scrolling area to display said second item while said first item remains selected, said direction determined by the location of said predetermined scrolling area relative to said first region; and

depositing at least said first item into said second item by positioning the cursor over said second item and by placing said switch in a second predetermined position.

19. In a computer controlled display system having a display wherein a plurality of regions may be displayed including at least a first region, said first region having at least a first item within a visible display area of said first region and said first region having at least one item, including a second item, which is not within the visible display area of said first region, a method for scrolling the contents of said first region to display said second item comprising:

selecting at least said first item within said first region by positioning a cursor over said first item so that said first item is associated with said cursor for further operation or manipulation;

positioning said cursor over a predetermined scrolling area and dragging an image of said first item displayed adjacent said cursor;

determining that a predetermined period of time has elapsed while the cursor has been positioned in said predetermined scrolling area; and

scrolling the contents of said first region in a direction corresponding to said predetermined scrolling area to display said second item while said first item remains selected and its image remains displayed adjacent said cursor.
