Abstract

A dual function computer mouse including: a housing; a first sensor for measuring a relative movement of the housing with respect to a surface and outputting a corresponding first signal; a second sensor for measuring the motion of the housing and outputting a corresponding second signal; a processor for converting the first and second signals from the first and second sensors into a corresponding cursor movement; and a switch having a first position for operatively connecting one of the first or second sensors to the processor and a second position for operatively connecting the other of the first or second sensors to the processor. Also provided is a computer having the computer mouse of the present invention.

Claims

1. A dual function computer mouse comprising:

a housing;

a first sensor for measuring a relative movement of the housing with respect to a surface and outputting a corresponding first signal;

a second sensor for measuring the motion of the housing and outputting a corresponding second signal;

a processor for converting the first and second signals from the first and second sensors into a corresponding cursor movement; and

a switch having a first position for operatively connecting one of the first or second sensors to the processor and a second position for operatively connecting the other of the first or second sensors to the processor.

2. The mouse of claim 1, wherein the processor is a digital signal processor.

3. The mouse of claim 1, further comprising means for automatically switching from one of the first or second positions to the other of the first or second positions.

4. The mouse of claim 1, further comprising a roller ball rotatably disposed in the housing, wherein the first sensor measures a rotation of the roller ball on the surface.

5. The mouse of claim 4, further comprising means for automatically switching from one of the first or second positions to the other of the first or second positions, wherein the means comprises a first spring disposed between the housing and the switch and a second spring disposed between the roller ball and the switch such that when the roller ball is placed on the surface the roller ball and second spring bias the switch into the first position to operatively connect the first sensor to the processor and when the roller ball is removed from the surface, the first spring biases the switch into the second position to operatively connect the second sensor to the processor.

6. The mouse of claim 1, wherein the switch is a manually operated switch having a switching means disposed on a surface of the housing.

7. The mouse of claim 1, wherein the first sensor is a light diode.

8. A computer comprising:

a display having a cursor displayed thereon for interaction with a computer interface; and

a dual function mouse, the dual function mouse having a housing, a first sensor for measuring a relative movement of the housing with respect to a surface and outputting a corresponding first signal, a second sensor for measuring the motion of the housing and outputting a corresponding second signal;

a processor for converting the first and second signals from the first and second sensors into a corresponding cursor movement, and a switch having a first position for operatively connecting one of the first or second sensors to the processor and a second position for operatively connecting the other of the first or second sensors to the processor.

9. The computer of claim 8, wherein the processor is a digital signal processor.

10. The computer of claim 8, wherein the mouse further comprises means for automatically switching from one of the first or second positions to the other of the first or second positions.

11. The computer of claim 8, further comprising a roller ball rotatably disposed in the housing, wherein the first sensor measures a rotation of the roller ball on the surface.

12. The computer of claim 11, further comprising means for automatically switching from one of the first or second positions to the other of the first or second positions, wherein the means comprises a first spring disposed between the housing and the switch and a second spring disposed between the roller ball and the switch such that when the roller ball is placed on the surface the roller ball and second spring bias the switch into the first position to operatively connect the first sensor to the processor and when the roller ball is removed from the surface, the first spring biases the switch into the second position to operatively connect the second sensor to the processor.

13. The computer of claim 8, wherein the switch is a manually operated switch having a switching means disposed on a surface of the housing.

14. The computer of claim 8, wherein the first sensor is a light diode.

15. A method for automatically switching between dual functions of a computer mouse, the method comprising:

contacting at least a portion of the computer mouse with a surface to terminate a first function and initiate a second function; and

removing the contact of the mouse from the surface to terminate the second function and initiate the first function.

16. The method of claim 15, wherein the contacting step comprises contacting a roller ball disposed in the computer mouse with the surface.

17. The method of claim 16, wherein the second function is the detection of a rotation of the roller ball and the conversion of the detected rotation into a corresponding computer cursor movement.

18. The method of claim 17, wherein the first function is the detection of a motion of the mouse and the conversion of the detected motion into a corresponding computer cursor movement.
