1. A method for generating computer simulation signals in response to the orientation of a moveable object from a plurality of electronic linear accelerometers mounted on the moveable object in cooperative operation with an external tracking system disposed relative to the moveable object, the method comprising the steps of:

  • processing linear acceleration signals generated from the plurality of electronic linear accelerometers mounted on the moveable object;

    generating orientation signals associated with the movement of the object in three degrees of freedom as a function of the linear acceleration signals;

    generating computer simulation signals in response to the orientation signals;

    processing tracking data signals associated with the object generated from the external tracking system disposed relative to the moveable object; and

    modifying the orientation signals as a function of the tracking data signals.
