Effect Of The Filtered Visual Feedback Information On Postural Control
説明
Effects of the filtered visual feedback information on the human postural control characteristics have been analyzed to examine the hypothesis that the visual feedback information used to stabilize the posture is processed in a discrete-time fashion by the postural control center in the brain. In the experiments, the test subject stood upright and was watching the image of a vertical line displayed in the three dimensional visor display. The signal of the image was filtered through a personal computer system. The body sway was analyzed when the parameter of each filter was changed. The results could support the hypothesis. It has been concluded that repetitive renewal of the visual information with sampling period shorter than about 0.3sec to O.5sec is necessary for stabilization of the posture.
