In recent years, a ship-handling simulator should be used for seafarers' training and/or maritime researches intended for bridge team composed of pilot, master, mates, crew, etc. But visual system of ship-handling simulator is never appropriate for plural members of bridge team. Nautical environment is vast and the members move in the bridge, so it is difficult that each member judges a situation in the visual environment simulated on the screen through one fixed viewpoint. The visual environment that has same timing and same accuracy for each member is required on evaluations of systems for navigation environment, simulator and/or training. The image through one fixed viewpoint is greatly influenced by position and movement of the member's viewpoint. For example, abeam motion of the viewpoint makes parallax to bearing of the image, and the parallax makes an error to relative motion of the image. Each member should have own visual environment follows up the movement of own viewpoint. In this paper, the multi-moving viewpoint system is proposed as new simulator's visual system in order to resolve mentioned problems, and validity of the system is discussed through the investigation of accuracy for ship-operator to grasp the movement and relative motion of image under multi-moving viewpoint.
