Abstract

A method comprising detecting a displacement of a slide disk relative to a frame and generating output information using first information configured to cause a pointer in a display to move to a position associated with the displacement and second information configured to cause the pointer in the display to move at a velocity associated with the displacement is provided.

Claims

1. A method comprising:

detecting a first displacement of a slide disk relative to a frame; and

generating output information using first information configured to cause a pointer in a display to move to a position associated with the first displacement and second information configured to cause the pointer in the display to move at a velocity associated with the first displacement.

2. The method of claim 1 further comprising:

generating the first information; and

generating the second information.

3. The method of claim 2 further comprising:

generating the first information according to a first gain value; and

generating the second information according to a second gain value.

4. The method of claim 1 further comprising:

generating the output information by summing the first information and the second information.

5. The method of claim 1 wherein the first displacement is in a first direction that is substantially parallel with a hypothetical plane that includes the frame.

6. The method of claim 5 further comprising:

detecting a second displacement of the slide disk in a second direction that is substantially perpendicular to the hypothetical plane; and

generating the output information in response to the second displacement exceeding a threshold.

7. The method of claim 1 further comprising:

generating the output information using a first proportion of the first information and a second proportion of the second information.

8. The method of claim 7 wherein the first proportion and the second proportion vary with an amount of the first displacement.

9. The method of claim 7 wherein the second proportion is zero in response to the first displacement being below a threshold.

10. A system comprising:

a slide disk;

a frame; and

a control unit;

wherein the control unit is configured to generate output information using first information configured to map a first displacement of the slide disk relative to the frame to a position of a pointer in a display and second information configured to map the first displacement of the slide disk relative to the frame to a velocity of the pointer in the display.

11. The system of claim 10 wherein the control unit includes a sense module configured to detect the first displacement.

12. The system of claim 10 wherein the control unit includes a position unit, a rate unit, and an output unit, wherein the position unit is configured to generate the first information and provide the first information to the output unit, and wherein the rate unit configured to generate the second information and provide the second information to the output unit.

13. The system of claim 12 wherein the position unit is configured to generate the first information according to a first gain value, and wherein the rate unit is configured to generate the second information according to a second gain value.

14. The system of claim 11 wherein the control unit is configured to generate the output information by summing the first information and the second information.

15. The system of claim 11 wherein the first displacement is in a first direction that is substantially parallel with a hypothetical plane that includes the frame.

16. The system of claim 15 wherein the control unit includes a sense module configured to detect a second displacement of the slide disk in a second direction that is substantially perpendicular to the hypothetical plane and a control module configured to cause the output unit to generate the output information in response to the second displacement exceeding a threshold.

17. The system of claim 11 wherein the control unit is configured to generate the output information using a first proportion of the first information and a second proportion of the second information.

18. The system of claim 17 wherein the first proportion and the second proportion vary with an amount of the first displacement.

19. The system of claim 17 wherein the second proportion is zero in response to the first displacement being below a threshold.

20. A system comprising:

a display; and

a pointing system including a slide disk and a frame;

wherein the pointing system is configured to generate output information using first information configured to cause a pointer in the display to move to a position associated with a displacement of the slide disk relative to the frame and second information configured to cause the pointer in the display to move at a velocity associated with the displacement.
