Abstract:
1. An input device for scrolling an image relative to an image display screen along perpendicular axes, said device comprising: a housing having at least one opening; and a scroll wheel assembly provided within said housing, said scroll wheel assembly including a rotatable member that is rotatable about a first axis extending within said housing and slideably movable about a second axis within said opening, said first axis and said second axis being perpendicular to each other; and a movement sensing system configured to sense rotational movement of said rotatable member about said first axis for scrolling the image in a first scrolling direction; a plurality of sensors for detecting tensile extension force to the sensors and the force responsive to, the sliding movement of said rotatable member about the second axis for scrolling the image in a second scrolling direction perpendicular to the first scrolling direction, the sensors resilient extensible; wherein the image is operable to scroll in the second direction responsive to the detected extension force.
