Abstract: A mouse provides multiple cursor control input devices. A first input device is a tracking ball. The second input device may be a tracking ball, a finger pad, or a joy stick, among other input devices. The second input device provides a secondary control of cursor movement that is combined with the input of the first input device to provide full cursor control. In one embodiment, the second input is scaled by a scaling factor and then combined with the first input. In another embodiment, both the first input and the second input are scaled before they are combined. In another mouse, a single input is provided that is scaled by one of a plurality of scaling factors. The scaling factor may be altered to another one of the plurality of scaling factors via mouse input, for example a button input.
