Perceptual disturbances predicted in zero-g through three-dimensional modeling.

摘要: Perceptual disturbances in zero-g and 1-g differ. For example, the vestibular coriolis (or "cross-coupled") effect is weaker zero-g. In 1-g, blindfolded subjects rotating on-axis experience perceptual upon head tilt, but effects diminish Head tilts during centrifugation are investigated here by means of three-dimensional modeling, using a model that was previously used to explain reduction effect. The model's foundation comprises laws physics, including linear-angular interactions three dimensions. Addressed question: zero-g, will be as weak rotation? Centrifugation simulated first, with subject supine, toward center. most noticeable result concerned direction yaw. clockwise centrifuge rotation, greater arose simulations yaw counterclockwise (as viewed from top head) than for clockwise. then same "supine" orientation. result: rotation. addition, clockwise-counterclockwise differences did not appear contrast 1-g.
