This paper is concerned with movements and stability of man gazing at a moving picture in a darkroom. These experiments studied to clarify the relation between visual information and postures. A worker may indirectly be exposed vibration when the objects around himswing. This is not only a problem for workers but also when he operates a large plant, it is a severe problem for the system if his posture swings and makes a mistake. The barpicture a subject gazes at was made with a computer in this experiments. In the first case, the center of gravity of a subject was measured when the bar swings right and left in front of him and the equilibrium line deviates gradually right or left. In the second case, the effects of gazing for a long time on subject's posture were measured. As results, our center of gravity deviates in the same direction as the equilibrium line deviates. And almost all subjects tune to the swinging bar in 5 min after they start their examinations, that is, this time may be the limit we can control our posture when we are gazing at a swinging bar in a darkroom.
