Abstract

A touchpad input controller receives user input relating to a display. The input controller includes a facing surface that faces a user when the controller is held in the user'"'"'s hand or hands during use, and one or more non-facing surfaces that each faces away from the user when the controller is held the user'"'"'s hand or hands during use. At least one non-facing surface includes a touchpad input area that is positioned to be accessed by at least one user finger for receiving user input. The facing surface including a display on which the results of user input received at the touchpad input area is displayed. The touchpad input area includes a mapping to a virtual keyboard layout for receiving keyboard-equivalent input from the user at the touchpad input area.

Claims

1. A touchpad input controller for receiving user input relating to a display, comprising:

a facing surface that faces a user when the controller is held in the user'"'"'s hand or hands during use;

one or more non-facing surfaces that each faces away from the user when the controller is held in the user'"'"'s hand or hands during use, at least one non-facing surface including a touchpad input area that is positioned to be accessed by at least one user finger for receiving user input.

2. The input controller of claim 1 in which the touchpad input area is included on a non-facing surface that is opposite the facing surface.

3. The input controller of claim 2 in which the touchpad input area includes a mapping to a virtual keyboard layout for receiving keyboard-equivalent input from the user at the touchpad input area.

4. The input controller of claim 3 further including a free motion mapping in which the touchpad input area is mapped to free cursor motion across the display.

5. The input controller of claim 1 further including a free motion mapping in which the touchpad input area is mapped to free cursor motion across the display.

6. The input controller of claim 1 in which the touchpad input area includes right- and left-side segments that are accessible and active for receiving user input simultaneously by at least one finger of each of the user'"'"'s right and left hands, respectively.

7. The input controller of claim 6 in which the touchpad input area includes a mapping to a virtual keyboard layout for receiving keyboard-equivalent input from the user at the touchpad input area, whereby the right- and left-side segments are mapped to keys that are accessible user input simultaneously by at least one finger of each of the user'"'"'s right and left hands, respectively.

8. The input controller of claim 1 in which the right- and left-side segments are portions of a single touchpad input area.

9. The input controller of claim 1 in which the right- and left-side segments are separate touchpad input areas.

10. The input controller of claim 1 in which the facing surface includes a display on which the results of user input received at the touchpad input area is displayed.

11. The input controller of claim 1 in which the display is not included in the input controller.

12. The input controller of claim 1 further comprising one or more control keys other than the touchpad input area positioned to be accessed by at least one user finger for receiving user input.

13. A touchpad input controller for receiving user input relating to a display, comprising:

a touchpad input area that is positioned to be accessed by at least one user finger for receiving user input, the touchpad input area including a mapping to a virtual keyboard layout for receiving keyboard-equivalent input from the user at the touchpad input area; and

a display rendering of the virtual keyboard layout indicating each keyboard-equivalent input from the user at the touchpad input area.

14. The input controller of claim 13 further including a free motion cursor mapping in which the touchpad input area is mapped to a free motion cursor display rendering.

15. The input controller of claim 14 further including a user-operable control for switching between the mapping to the virtual keyboard layout and the free motion cursor mapping.

16. The input controller of claim 15 further including a physical key or button that functions as the user-operable control for switching between the mapping to the virtual keyboard layout and the free motion cursor mapping.

17. The input controller of claim 15 further including a display rendering of a virtual key or button that functions as the user-operable control for switching between the mapping to the virtual keyboard layout and the free motion cursor mapping.

18. The input controller of claim 15 further including a mapping of a first region of the touchpad input area to the virtual keyboard layout and a second region of the touchpad input area to the free motion cursor mapping.

19. The input controller of claim 13 in which the touchpad area is pivotable between a facing orientation that faces the user when the controller is in use and a non-facing orientation that faces away from the user when the controller is in use, the controller inverting the mapping to the virtual keyboard layout from the touchpad input area when the touchpad input area is pivoted between the facing and non-facing orientations.

20. The input controller of claim 13 in which the touchpad area is pivotable in a vertical direction between the facing and non-facing orientations and the controller vertically inverts the mapping to the virtual keyboard layout from the touchpad input area.

21. The input controller of claim 13 in which the touchpad area is pivotable in a horizontal direction between the facing and non-facing orientations and the controller horizontally inverts the mapping to the virtual keyboard layout from the touchpad input area.

22. The input controller of claim 13 in which user input of a keyboard selection is entered by the user at the touchpad input area.

23. The input controller of claim 13 further including a physical key or button and in which in which user input of a keyboard selection is entered by user activation of the physical key or button.

24. The input controller of claim 13 in which the touchpad input area is included in a laptop computer.

25. The input controller of claim 13 further including a free motion cursor mapping in which the touchpad input area is mapped to a free motion cursor display rendering of a video game, wherein the input controller operates as a game controller for the video game.

26. A touchpad input controller for receiving user input relating to a display, comprising:

a touchpad input area that is positioned to be accessed by at least one user finger for receiving user input, the touchpad input area including first and second mappings to a virtual keyboard layout for receiving keyboard-equivalent input from the user at the touchpad input area when the touchpad is in first and second orientations, respectively; and

a display rendering of the virtual keyboard layout indicating each keyboard-equivalent input from the user at the touchpad input area.

27. The input controller of claim 26 in which the touchpad area is pivotable between a facing orientation that faces the user when the controller is in use and a non-facing orientation that faces away from the user when the controller is in use, the controller inverting the mapping to the virtual keyboard layout from the touchpad input area when the touchpad input area is pivoted between the facing and non-facing orientations.

28. The input controller of claim 26 further comprising a detector for detecting when the touchpad is in the first and second orientations.

29. The input controller of claim 28 in which the detector includes an accelerometer.
