Abstract (in Japanese) (See Japanese page) 
(in English) It is considered that the cause of seasickness is a conflict of the visual and the vestibular sensations, and supposed that the conflict can be reduced by viewing a scenery over the sea. Thus we propose movie-shooting methods on board to inhibit seasickness. A movie is shot within a moving image which brings an optokinetic sensation to reduce the sensory conflict . Virtual environment (VE) giving a clear perception of the vertical is presented as the moving image, which rotates in the inverse direction to ship motion to keep stationary in the earth-fixed frame of reference. The movie is projected in two ways : (a) the whole image of the movie rotates in accordance with the VE, and (b) the inner world of the movie rotates but its trimmed image keeps its position in a screen. In the ExperimentⅠ, conducted on the sea, effects of the above methods on inhibiting seasickness were determined. In the ExperimentⅡ, using a simulator, the movie-shooting methods were compared under the identical motion of a ship. In the ExperimentⅢ, conducted on the sea, the time courses of seasickness severity during movie watching in the above methods were measured. This study showed that movie-shooting with VE stationary in the earth-fixed frame produced marked effect on inhibiting seasickness.
