Abstract

A mouse input device includes a tracking device and a secondary input device. The tracking device tracks movement of the mouse input device over an underlying surface. The secondary input device is located on a surface of the mouse input device. The secondary input device has a sliding structure. A magnitude and a direction of motion of the sliding structure with respect to the surface of the mouse input device is monitored.

Claims

1. A mouse input device comprising:

a tracking device that tracks movement of the mouse input device over an underlying surface; and

,

a secondary input device located on a surface of the mouse input device, the secondary input device having a sliding structure, wherein a magnitude and a direction of motion of the sliding structure with respect to the surface of the mouse input device is monitored.

2. A mouse input device as in claim 1 wherein the secondary input device is also implemented to control panning of contents of an active window on a computer display.

3. A mouse input device as in claim 1 wherein the secondary input device is also implemented to control zooming.

4. A mouse input device as in claim 1 wherein the tracking device includes an image array.

5. A mouse input device as in claim 1 wherein vertical pressure on the sliding structure causes the secondary input device to activate.

6. A mouse input device as in claim 1 wherein springs are used to re-center the sliding structure.

7. A mouse input device as in claim 1 additionally comprising:

a secondary input device controller that determines a location of the sliding structure with respect to the surface of the mouse input device; and

,

a mouse controller that receives output from the tracking device and output from the secondary input device controller.

8. A mouse input device as in claim 1 wherein activation of the secondary input device causes a cursor within the active window to change to a special shape that indicates the secondary input device has been activated.

9. A mouse input device as in claim 1 wherein the secondary input device can operate in multiple modes, including a joystick mode where a position of the sliding structure is mapped to velocity of a cursor.

10. A mouse input device as in claim 1 wherein size of the sliding structure can be selected by a user.

11. A mouse input device comprising:

means for tracking movement of the mouse input device over an underlying surface; and

,

means for providing a secondary input based on a magnitude and a direction of motion of a sliding structure with respect to a surface of the mouse input device.

12. A mouse input device as in claim 11 wherein vertical pressure on the sliding structure causes activation of the means for providing a secondary input.

13. A mouse input device as in claim 11 wherein the means for providing a secondary input is used to control panning.

14. A mouse input device as in claim 11 wherein activation of the means for providing a secondary input causes a cursor within the active window to change to a special shape that indicates the means for providing a secondary input has been activated.

15. A method comprising:

tracking movement of the mouse input device over an underlying surface; and

,

providing a secondary input based on a magnitude and a direction of motion of a sliding structure with respect to a surface of the mouse input device.

16. A method as in claim 15 additionally comprising:

controlling zooming of the contents of the active window based on the magnitude and the direction of motion of the sliding structure with respect to the surface of the mouse input device.

17. A method as in claim 15 additionally comprising:

activating control of panning as a result of application of vertical pressure on the sliding structure.

18. A method as in claim 15 additionally comprising:

re-centering the sliding structure using springs.

19. A method as in claim 15 additionally comprising:

controlling panning of the contents of the active window based on the magnitude and the direction of motion of the sliding structure with respect to the surface of the mouse input device.

20. A method as in claim 15 additionally comprising:

operating in multiple modes, including a joystick mode where a position of the sliding structure maps to velocity of a cursor.
