Abstract

A computer input device used to input coordinates and three-dimensional graphical information into a computer. The device includes an acceleration sensor that has a fixed volume vessel containing a magnetic fluid. A non-magnetic inertial body is located in the magnetic fluid. Three magnetic field source are located on three perpendicular axes where each magnetic field source has an output for connection to a computer.

Claims

1. (Canceled)

2. A computer game input device comprising:

an acceleration sensor, wherein the acceleration sensor comprises;

a closed volume vessel containing magnetic fluid;

a non-magnetic inertial body contained in the vessel; and

at least three magnetic field sources located in pairs on three mutually perpendicular axes around the closed volume vessel, and wherein said at least three magnetic field sources have an output; and

a signal converter assembly wherein the output of said magnetic field sources is connected to an input of the signal converter assembly, and wherein outputs of the signal converter assembly provide coordinate information used to control computer generated objects.

3. The device of claim 2 wherein the magnetic field source comprises inductor coils serially connected to a current generator, wherein an output of the current generator is the output for the magnetic field sources.

4. The device of claim 2 wherein additional magnetic field sources are introduced into the proximity of the magnetic field sources.

5. The device of claim 2 wherein said magnetic field sources include one or more constant magnets.

6. The device of claim 2 wherein outputs of the signal converter assembly are in communication with a computer.

7. The device of claim 6 wherein the outputs of the signal converter assembly are in wireless communication with the computer.
