Abstract

An apparatus that includes a keyboard movable by a user while her hands are resting on the keyboard actuates a pointing device for a computer system. The movement of the keyboard maneuvers or steers the pointing device, and the user'"'"'s hands need never be lifted from or leave the keyboard. The apparatus actuating a pointing device includes a first tray and a second tray. The first tray has a surface, and a portion of the pointing device is located on the surface. The second tray is positioned above the first tray whereby motion of the second tray actuates the pointing device.

Claims

1. An apparatus for actuating a pointing device comprising:

a first tray having a surface, a portion of the pointing device being fixed on the surface; and

a second tray positioned above the first tray whereby motion of the second tray with respect to the first tray actuates the pointing device.

2. The apparatus of claim 1 wherein:

the first tray includes a bottom tray portion and a plurality of side tray portions, the bottom tray portion and the plurality of side tray portions defining a tray interior, the surface being located on one of the tray portions; and

wherein

the second tray is sized to fit in the first tray interior.

3. The apparatus of claim 1 further comprising a keyboard coupled to the second tray.

4. The apparatus of claim 3 wherein the keyboard includes:

a pointing device pick button; and

a means for selecting from a pointing device mode of operation and a keyboard mode of operation.

5. The apparatus of claim 1 wherein the second tray includes:

a pointing device pick button; and

a means for selecting from a pointing device mode of operation and a keyboard mode of operation.

6. The apparatus of claim 1 wherein the second tray is coupled to the pointing device.

7. The apparatus of claim 6 wherein the pointing device is a pointing stick.

8. The apparatus of claim 1 wherein the pointing device includes a plurality of sensors.

9. The apparatus of claim 8 wherein each of the plurality of sensors is a force sensitive resistor.

10. The apparatus of claim 1 wherein the pointing device includes a plurality of rollers.

11. The apparatus of claim 1 wherein the pointing device includes:

a slide, the slide allowing substantially linear reciprocating movement; and

a sensor coupled to the slide, the sensor capable of detecting the substantially linear reciprocating movement of the slide.

12. The apparatus of claim 1 wherein the pointing device is a touchpad and the second tray includes a raised portion for actuating the touchpad.

13. A pointing device comprising:

a plurality of sensors, each sensor capable of detecting motion in at least one direction;

a first tray having a surface, at least one of the plurality of sensors being fixed on the surface; and

a second tray positioned above the first tray whereby motion of the second tray with respect to the first tray actuates the at least one of the sensors.

14. The pointing device of claim 13 further comprising a keyboard coupled to the second tray.

15. The pointing device of claim 14 wherein the keyboard includes:

a pointing device pick button; and

a means for selecting from a pointing device mode of operation and a keyboard mode of operation.

16. The pointing device of claim 13 wherein the second tray includes:

a pointing device pick button; and

a means for selecting from a pointing device mode of operation and a keyboard mode of operation.

17. The pointing device of claim 13 wherein the plurality of sensors is a plurality of force sensors.

18. The pointing device of claim 16 wherein each of the plurality of force sensors is a force sensitive resistor.

19. The pointing device of claim 13 wherein the each of plurality of the plurality of sensors is a roller.

20. The pointing device of claim 13 further comprising a plurality of slides, each slide allowing substantially linear reciprocating movement, each of the plurality of sensors being coupled to a respective slide, each sensor being capable of detecting the substantially linear reciprocating movement of its respective slide.

21. A computer system comprising:

a chassis;

a processor;

a memory electrically coupled to the processor;

a pointing device electrically coupled to the processor; and

an apparatus for actuating the pointing device including;

a first tray having a surface, a portion of the pointing device being fixed on the surface; and

a second tray positioned above the first tray whereby motion of the second tray with respect to the first tray actuates the pointing device.

22. The computer system of claim 21 further comprising a pointing device pick button located on the chassis.

23. The computer system of claim 21 further comprising a pivot point located on the chassis, the pivot point on which a user can place a thumb to facilitate movement of the second tray.

24. The computer system of claim 21 further comprising a keyboard coupled to the second tray.

25. The computer system of claim 24 wherein the keyboard includes:

a pointing device pick button; and

a means for selecting from a pointing device mode of operation and a keyboard mode of operation.

26. The computer system of claim 21 wherein the second tray includes:

a pointing device pick button; and

a means for selecting from a pointing device mode of operation and a keyboard mode of operation.

27. The computer system of claim 21 wherein the second tray is coupled to the pointing device.

28. The computer system of claim 27 wherein the pointing device is a pointing stick.

29. The computer system of claim 21 wherein the pointing device includes a plurality of sensors.

30. The computer system of claim 29 wherein each of the plurality of sensors is a force sensitive resistor.
