Abstract: The motion simulation system of the present invention is basically comprised of three coordinated components or sub-systems. The first sub-system consists of mechanical structure in the form of seats, rods, bearings and hydraulic cylinders employed to mechanically convey eight directions of motion to a participant occupying one of the seats. The second sub-system is found in a hydraulic circuit used to convert electrical signals from a digital controller into hydraulic motion signals for the mechanical system. Finally, the last component of the motion simulator is the electrical circuitry which incorporates a projector for projecting a moving image on the screen coupled with appropriate analog and digital circuitry in order to produce a series of motion signals used to individually move the seats in directions which would correspond to the motion taking plate in the point-of-view film being displayed on the screen.
