Abstract

A system and method whereby the cursor displayed by a data processing system on a monitor is automatically moved to a preselected location on the desktop, called the parking area, whenever it has been inactive for a predetermined amount of time. If the window focus is dependent on the location of the cursor, the parking area can be located within a specified window.

Claims

1. A data processing system for displaying data on a display device and for locating a cursor displayed on a monitor of said data processing system, said system comprising:

a central processing unit coupled via a bus to one or more storage media;

a monitor coupled to a display adapter for displaying information related to an application and said cursor, said display adapter coupled to said central processing unit via said bus;

a pointing device for controlling said cursor, said pointing device coupled to said central processing unit via a user interface adapter and said bus;

detecting means for detecting an attribute of said pointing device; and

parking means for parking said cursor at a predetermined location on said monitor when said detecting means detects that said attribute of said pointing device has achieved a predetermined value.

2. The system of claim 1, wherein said pointing device is a mouse.

3. The system of claim 1, further comprising timing means for measuring a time period of pointing device inactivity.

4. The system of claim 3, wherein said parking means parks said cursor at said predetermined location when said time period of pointing device inactivity measured by said timing means exceeds a predetermined time limit.

5. The system of claim 1, further comprising at least one program window displayed on said monitor, said at least one program window having a border and one of said at least one program window having a focus.

6. The system of claim 5, wherein said predetermined location for parking said cursor is positionally related to said border of said at least one window having said focus.

7. The system of claim 1, further comprising a keyboard for inputting information to said central processing unit.

8. The system as recited in claim 1, wherein said attribute of said pointing device is activity of said pointing device, and wherein said predetermined value is inactivity of said pointing device.

9. In a computer system having a central processing unit coupled to a display device displaying a cursor and a pointing device for controlling said cursor, a method for parking said cursor comprising the steps of:

measuring a time period of pointing device inactivity; and

parking said cursor in a predetermined location when said time period of pointing device inactivity exceeds a predetermined time limit.

10. The method of claim 9, wherein said predetermined location is positionally related to a border of a program window.

11. The method of claim 9, wherein said pointing device for controlling said cursor is a mouse.

12. A system for parking a mouse pointer in a predetermined location on a display screen coupled to a data processing system, said system comprising:

means for measuring a time period of mouse inactivity; and

means for parking said mouse pointer in said predetermined location when said time period of mouse inactivity exceeds a predetermined time limit.
