Abstract
A computer input device includes a magnetized fluid and an inertial body within the magnetized fluid. A signal converter provides angular acceleration information based on behavior of the inertial body. The computer input device can be attached to a Virtual Reality Suit, or can be used to control computer-generated graphical objects. The inertial body can be non-magnetic. The body can be solid or hollow. Electromagnets and/or permanent magnets can be used for magnetizing the fluid. Magnetic coils sense the changes in the magnetic flux lines. Signals from the magnetic coils are used by the signal converter to calculate the angular acceleration. A housing encloses the magnetized fluid and the inertial body.
