The notion of a conventional mouse is extended to provide an extended number of simultaneously adjustable user interface parameters. In one family of realizations, one or more trackballs, touchpads, or other types of user interface sensors may be added to a traditional mouse to provide additional user interface parameters. These additional user interface sensors may be simultaneously adjusted along with any movement of the mouse. The overall physical configuration may provide mixed physical modalities for adjusting a common pair of user interface parameters to prevent or ease hand fatigue, or to provide alternate parameter adjustment offsets, warpings, or resolutions. The additional user interface sensors, particularly trackballs and touchpads, may also be specially configured to provide up to six or more simultaneously adjustable and widely-variable user interface parameters.
