ABSTRACT:
A mouse system is disclosed for data entry and control and wherein a rolling force of the ball is made adjustable to suit an operator's preference. A friction pad or a magnetic force may be applied to the ball to change and adjust the ball rolling force. Alternatively, a free roller in contact with the ball has its rotational force adjustable by friction or magnetic forces acting on the free roller or its axle. The mouse system disclosed is designed ergonomically to ease operator fatigue and increase an operator's efficiency.
