Japanese Patent JP3652378
Kind Code:

Abstract:
A mouse or trackball comprising a rotationally-symmetrical member (sphere or cylinder). The sphere or cylinder can be braked by means of baking means which receive an appropriate control signal from a data processing apparatus such as a computer. Mechanical feedback to the operator is thus realised. In accordance with the invention, the mouse or trackball also comprises acceleration means which are capable of positively accelerating the sphere or cylinder in a desired direction. The mechanical feedback is thus substantially improved.
