Abstract

A mouse pointing device and a method of providing movement data and position data with a mouse pointing device. The device comprises: (1) a mouse body adapted to traverse a substantially planar surface, (2) a mouse movement tracking mechanism, coupled to the mouse body, for producing movement data regarding movement of the mouse body relative to the substantially planar surface and (3) a user position tracking mechanism, having a substantially planar mechanism surface occupying a portion of a surface of the mouse body, for producing contact data regarding contact between the mechanism surface and a user, the contact data including location data regarding a location of a contact point, on a plane of the mechanism surface, between the mechanism surface and the user.

2. The device as recited in claim 1 wherein said touchpad is substantially elongated, said location data regarding a linear location of said contact point on said plane of said touchpad.

3. The device as recited in claim 1 wherein said contact data further includes pressure data regarding a pressure at said contact point.

4. The device as recited in claim 1 further comprising communication and control circuitry, contained within said mouse body, for transmitting said movement data and said contact data to an associated computer system.

5. The device as recited in claim 1 wherein said touchpad includes non-coplanar ridges defining regions in an area of said touchpad, said non-coplanar ridges producing a tactile indication of said regions to said user.

6. The device as recited in claim 1 further comprising a driver, executable in general purpose data processing and storage circuitry in an associated computer system, for receiving said movement and position data from said mouse pointing device, said driver making said movement and position data available to an application program executable on said general purpose data processing and storage circuitry.

7. The device as recited in claim 1 wherein said surface of said mouse body is an upper surface thereof.

8. The device as recited in claim 1 wherein communication and control circuitry within said mouse pointing device includes a limited operating mode in which said user position tracking mechanism is caused to function as a momentary switch.

9. A method of providing movement data and position data with a mouse pointing device, comprising the steps of:

traversing a substantially planar surface with a mouse body of said mouse pointing device;

producing movement data with a mouse movement tracking mechanism coupled to said mouse body, said movement data regarding movement of said mouse body relative to said substantially planar surface; and

producing contact data with a user position tracking mechanism having a substantially planar pressure-sensitive touchpad occupying a portion of a surface of said mouse body, said contact data regarding contact between said touchpad and a user, said contact data including location data regarding a location of a contact point, between said touchpad and said user, said touchpad including demarcations defining virtual buttons on said touchpad for use in a graphical user interface mode, said mouse movement tracking mechanism and said user position tracking mechanism configured such that a user need not take action to disable one of said tracking mechanisms in order to for said user to use the other one of said tracking mechanisms.

10. The method as recited in claim 9 wherein said step of producing said contact data comprises the step of producing location data regarding a linear location of said contact point on said plane of said touchpad, said touchpad being substantially elongated.

11. The method as recited in claim 9 wherein said step of producing said contact data comprises the step of producing pressure data regarding a pressure at said contact point.

12. The method as recited in claim 9 further comprising the step of transmitting said movement data and said contact data to an associated computer system with communication and control circuitry contained within said mouse body.

13. The method as recited in claim 9 further comprising the step of defining regions in an area of said mechanism surface with non-coplanar ridges on said mechanism surface, said non-coplanar ridges producing a tactile indication of said regions to said user.

14. The method as recited in claim 9 further comprising the step of receiving said movement and position data from said mouse pointing device into a driver executable in general purpose data processing and storage circuitry in an associated computer system, said driver making said movement and position data available to an application program executable on said general purpose data processing and storage circuitry.

15. The method as recited in claim 9 wherein said step of producing said contact data comprises the step of applying force to said user position tracking mechanism, said user position tracking mechanism occupying a portion of an upper surface of said mouse body.

16. The method as recited in claim 9 further comprising the step of causing said user position tracking mechanism to function as a momentary switch.

17. A mouse pointing device comprising:
