Patent ID: 8692767

Claim:
An input device comprising: a sensing system adapted to detect motion of an object on a surface within a sensing region; and a processing system coupled to the sensing system, the processing system adapted to: effect movement of a display pointer on a display in a first direction in response to motion of the object on the surface, wherein the movement of the display pointer substantially corresponds to the motion of the object on the surface; effect continued movement of the display pointer in the first direction in response to the object being removed from the surface; effect movement of the display pointer in a second direction on the display in response to the display pointer reaching an edge portion of the display during the continued movement in the first direction, the second direction being different from the first direction; and effecting cessation of the continued movement of the display pointer when the object is brought back within the sensing region after the object had been previously removed from the sensing region; wherein the continued movement of the display pointer in the first direction is at a first speed, the movement of the display pointer in the second direction is initially at a non-zero second speed and the second speed is a specified non-zero value based on at least one of a resolution of the display and a size of a screen element rendered by the display.
