Abstract
An input device including a scroll wheel assembly for moving an image in multiple directions on a display screen. The scroll wheel assembly may include a finger-engagable control member that may be endlessly rotated about a rotation axis and a tilt sensor containing a tilt contact member coplanar with the finger-engagable control member and oriented in a substantially vertical, downward orientation such that pivoting of the finger-engagable control member may move the tilt contact member laterally to contact laterally disposed contact switches. In another example, the finger-engagable control member contains a flexible blade at an underside for biasing the scroll wheel assembly to an upright position.
