1. A mouse system, comprising:
- a mouse ball;
means for retaining and sensing rotation of the mouse ball;
operator accessible adjusting means for permitting each individual operator of the mouse system to select a rolling force of the mouse ball which is specifically desired by the particular operator to satisfy his or her preference for a specific feel and to thus satisfy a requirement of the operator during use; and
said adjusting means comprising said ball having a magnetic force responsive core and wherein a magnet means is provided in close proximity to a periphery of the ball for exerting a magnetic force on the core, and wherein a magnet adjustment means is provided for changing a spacing of the magnet means from the periphery of the ball.

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.
