Abstract
A method of moving an object in a generally circular manner on the surface of a touchpad and causing a list to be scrolled as long as the object is moving, wherein a method is provided for activating a scrolling function, wherein a method is provided for determining what direction scrolling should occur based upon a direction of movement when scrolling is engaged, and wherein the direction of scrolling is only changed by an abrupt change in direction of the object.

A method for scrolling using a touchpad for interface control, said method comprising the steps of:
- 1) providing a touchpad including a linear scrolling region and a general purpose area of operation;
- 2) touching down with a pointing object in the linear scrolling region to engage a scrolling mode;
- 3) moving the pointing object in an initial direction of scrolling to thereby begin a scrolling action;
- 4) moving the pointing object from the linear scrolling region to the general purpose area, wherein the scrolling action continues in the initial direction;
- 5) moving the pointing object along a curvilinear path to continue the scrolling action in the initial direction;
- and
- 6) keeping the pointing object disposed on the touchpad as long as the scrolling action is desired, and removing the pointing object to disengage the scrolling mode.
