Abstract
Scrolling or other user interface functions are provided in response to two-dimensional inputs produced by a touchpad or other input device. The user initially touches the touch sensor in an area near a periphery of the touch sensor and moves his or her finger along the periphery of the device, and then provides a subsequent motion of the finger across the touch sensor in a direction that departs from the periphery. The amount of scrolling produced on the computing system may be determined as a function of a distance moved by the user's finger.
