A force feedback wheel is provided on a mouse or other interface device manipulated
by a user. A sensor detects a position of the mouse in a workspace and sends a
position signal to a connected host computer indicating that position. A rotatable
wheel is mounted upon the manipulandum and rotates about a wheel axis, where a
wheel sensor provides a wheel signal to the host computer indicating a rotary position
of the wheel. A wheel actuator coupled to the rotatable wheel applies a computer-modulated
force to the wheel about the wheel axis. The mouse can be a standard mouse or a
force-feedback mouse, where forces are applied in the mouse workspace. The host
computer is preferably running a graphical environment, where the force applied
to the wheel can correspond with an event or interaction displayed in the graphical
environment. The wheel can also be included on other devices such as remote controls
and radios.
