Abstract

A computer system and method are presented that allow a computer system to optimize background task scheduling. The method involves monitoring for the physical presence of a user associated with the computer. When the monitoring indicates that the user is absent, a background task is scheduled and executed. A computer task scheduling system is also provided for optimizing computer usage through proper scheduling of computer tasks. This computer system includes a computer having a memory. In addition, a physical presence detector is included that monitors for the physical presence of a user of the computer. This detector is in communication with the computer and informs the computer when the user is present and absent.

Claims

1. A computer-implemented method for optimizing background task scheduling, comprising:

monitoring for the physical presence of a user associated with the computer; and

scheduling and executing at least one background task when the monitoring indicates that the user is not present.

2. The computer-implemented method of claim 1, further comprising, monitoring, after the scheduling and executing of the at least one background task have initiated, for the physical presence of the user, indicating the user has returned to the computer.

3. The computer-implemented method of claim 2, further comprising, suspending the at least one background task when the monitoring indicates the return of the user to the computer.

4. The computer-implemented method of claim 3, further comprising, continuing monitoring for the physical presence of the user and re-executing the suspended background task when the continuing monitoring indicates that the user is no longer present.

5. The computer-implemented method of claim 3, wherein the monitoring is performed by a selected one of the group of a proximity sensor, an infra-red detector, a photo-optical sensing device or a video sensing device.

6. The computer-implemented method of claim 5, wherein the at least one background task is a file indexing service.

7. A computer-implemented method for optimizing computer task scheduling, comprising:

monitoring for the physical presence of a user associated with the computer; and

scheduling and executing at least one computer task when the monitoring indicates that the user is not present.

8. The computer-implemented method of claim 7, further comprising, monitoring, after the scheduling and executing of the at least one computer task have initiated, for the physical presence of the user, indicating the user has returned to the computer.

9. The computer-implemented method of claim 8, further comprising, suspending the at least one computer task when the monitoring indicates the return of the user to the computer.

10. The computer-implemented method of claim 7, wherein the monitoring is performed by a selected one of the group of a proximity sensor, an infra-red detector, a photo-optical sensing device or a video sensing device.

11. The computer-implemented method of claim 10, wherein the at least one computer task is a background-type task.

12. The computer-implemented method of claim 10, further comprising continuing monitoring for the physical presence of the user and re-executing the suspended computer task when the continuing monitoring indicates that the user is no longer present.

13. A computer-readable medium containing instructions for optimizing computer task scheduling, the instructions comprising:

monitoring for the physical presence of a user associated with the computer; and

scheduling and executing at least one computer task when the monitoring indicates that the user is not present.

14. The computer-readable medium of claim 13, further comprising, monitoring, after the scheduling and executing of the at least one computer task have initiated, for the physical presence of the user, indicating the user has returned to the computer.

15. The computer-readable medium of claim 14, further comprising, suspending the at least one computer task when the monitoring indicates the return of the user to the computer.

16. The computer-readable medium of claim 15, further comprising continuing monitoring for the physical presence of the user and re-executing the suspended computer task when the continuing monitoring indicates that the user is no longer present.

17. A computer task scheduling system for optimizing computer usage through proper scheduling of computer tasks, comprising:

a computer having a memory; and

a physical presence detector that monitors for the physical presence of a user of the computer, the detector in communication with the computer to inform the computer when the user is present and absent.

18. The computer task scheduling system of claim 17, further comprising a task scheduler in the computer, the task scheduler scheduling and executing at least one computer task when the detector indicates that the user is absent.

19. The computer task scheduling system of claim 18, wherein the detector is one of the group of a proximity sensor, an infra-red detector, a photo-optical sensing device or a video sensing device.

20. The computer task scheduling system of claim 18, wherein the physical presence detector continues monitoring for the physical presence of a user after the task scheduler executes the at least one computer task.

21. The computer task scheduling system of claim 18, wherein the task scheduler is adapted to receive physical presence information from the detector so that the task scheduler can suspend computer tasks upon receiving information that the user is physically present.
