This study evaluated illumination and spatial disorientation under multisensory stimulation (visual, vestibular, tactile and proprioceptive receptor). In this paper, we investigated spatial disorientation in view of postural control and self-motion sensation.<BR>The flight simulator in National Aerospace Laboratory (NAL) was used. The subjects were 20 healthy young persons. The subject stood on the motionbase in front of a big screen. The image of a virtual room of JEM or a random dot pattern were projected on the screen. The image and the motionbase were tilted under computer control. Posture and perceived self-motion were affected by visual stimulation when the virtual image was used, especially when both the motionbase and image were tilted, but when the random dot pattern was projected, these effects were slight. We suppose that these effects were due to differences in the visual information that provided position cues. There was great individual variation in these postural responses. We suggest that this variation is due to individual differences in dependence on visual cues.
