Abstract

A method of using a capacitance-sensitive touchpad, wherein the touchpad includes a zone on a surface thereof, wherein touchdown of a pointing object within the zone enables activation of a scrolling function, wherein direction of scrolling is then controlled by a gesture by the pointing object, such as moving in a circular motion in a clockwise direction to move down in a list, and in a counter clockwise direction to move up in a list, and wherein fast and slow scrolling speeds are controlled by tapping functions within the scroll zone.

Claims

1. A method for performing scrolling in any active list shown on a display by using a touchpad, said method comprising the steps of:

1) providing a touchpad having a first scrolling activation zone that enables a scrolling function, and a non-activation region wherein touching down does not activate the scrolling function;

2) touching down with a pointing object in the first scrolling activation zone;

3) activating the scrolling function in an active list of items; and

4) moving the pointing object in a circular motion anywhere in the first scrolling activation zone and the non-activation region to perform scrolling of the items in the active list.

2. The method as defined in claim 1 wherein the method further comprises the steps of:

1) moving the pointing object in a first direction to perform scrolling in the active list in a first direction; and

2) moving the pointing object in an opposite direction relative to the first direction to perform scrolling in the active list in the opposite direction.

3. The method as defined in claim 1 wherein the method further comprises the step of changing a direction of scrolling at any time within the active list when the scrolling function is active by simply moving the pointing object in a direction that is opposite to a present direction of scrolling.

4. The method as defined in claim 1 wherein the method further comprises the step of using a size of a radius of the circular motion to determine a rate at which scrolling will occur.

5. The method as defined in claim 1 wherein the method further comprises the step of providing a second scrolling activation zone on the touchpad, wherein the first scrolling activation zone only activates fast scrolling, and wherein the second scrolling activation zone only activates slow scrolling.

6. The method as defined in claim 1 wherein the step of activating the scrolling function further comprises the step of activating the scrolling function for a predetermined list, regardless of whichever list is the active list.

7. The method as defined in claim 6 wherein the method further comprises the step of making the predetermined list a selectable list that can be changed by a user to be any list that can be made the active list.

8. The method as defined in claim 1 wherein the method further comprises the step of disposing the touchpad over the display, wherein the touchpad is substantially transparent to a user.

9. The method as defined in claim 8 wherein the method further comprises the step of enabling the display to indicate at least one button that can be activated by touchdown on the touchpad.

10. The method as defined in claim 9 wherein the method further comprises the steps of:

1) activating the at least one button by performing a touchdown within a boundary of the at least one button; and

2) increasing or decreasing a value controlled by the button by moving the pointing object in the circular motion.

11. The method as defined in claim 10 wherein the method further comprises the step of replacing the at least one button with at least one different button in a same location, wherein the at least one different button is activated by touchdown within the boundary of the at least one button.

12. The method as defined in claim 1 wherein the method further comprises the step of increasing or decreasing a value of a parameter by moving the pointing object in the circular motion.

13. The method as defined in claim 12 wherein the method of increasing or decreasing a value of a parameter further comprises the step of selecting the parameter from the group of parameters comprised of adjustments to volume, adjusting settings on an equalizer, adjusting brightness, adjusting contrast, adjusting speed forward or backward, skipping forwards and backwards among various items, zooming in or out, moving a view or a web page up or down, moving a channel selection up or down, and advancing forwards or backwards through items that may be selected such as tools or weapons in a game.

14. The method as defined in claim 1 wherein the method further comprises the steps of:

1) providing a touchpad;

2) performing a multiple-tap operation with a pointing object;

3) activating a scrolling function for a list of items shown on the display in response to the multiple-tap operation; and

4) moving the pointing object in a circular motion anywhere on the touchpad to perform scrolling of the items in the list.

15. The method as defined in claim 1 wherein the method further comprises the steps of:

1) providing a touchpad having a first parameter activation zone;

2) touching down with a pointing object in the first parameter activation zone; and

3) moving the pointing object in a circular motion anywhere on the touchpad to increase or decrease a value of the parameter.

16. A method for performing scrolling of items in a pre-determined list using a touchpad, said method comprising the steps of:

1) providing a touchpad having a first scrolling activation zone that enables a scrolling function, and a non-activation region wherein touching down does not activate the scrolling function;

2) touching down with a pointing object in the first scrolling activation zone;

3) activating the scrolling function in a predetermined list of items associated with the first scrolling activation zone; and

4) moving the pointing object in a circular motion anywhere in the first scrolling activation zone and the non-activation region to perform scrolling of the items in the list.

17. The method as defined in claim 16 wherein the method further comprises the step of making the predetermined list a selectable list that can be changed by a user.
