Abstract
Method for measuring the visually-induced postural instability of a person is described, the method comprising a display providing step (S1) during which a visual display device is provided. The display device is arranged so as to display a dynamic visual pattern in at least 50% of the lower half of the visual field of the person, leaving an upper half of the visual field of the person free. The method also comprises a display step (S2) during which a dynamic visual pattern is displayed on the visual display device. The method further comprises a measuring step (S3) during which a parameter representative of the postural instability is measured when the person is gazing at a fix target straight in front while having the dynamic visual pattern displayed on the visual display device.
