Abstract

A joystick, mouse, or trackball having a rotationally-symmetrical member. The joystick or the like can be braked by an appropriate control signal from a data processing apparatus such as a computer. Mechanical feedback to the operator is thus realized. In accordance with the invention, the joystick, mouse or trackball also includes an accelerator which is capable of positively accelerating the joystick, mouse or trackball in a desired direction. The mechanical feedback is thus substantially improved.
