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.

Abstract: Method for determining the relative amplitude of eye and head movements of an individual, comprising: —a target providing step during which a list of visual targets comprising at least two different visual targets is provided; —a reference positioning step; —a reference target providing step during which a reference target comprising a visual and auditory target is provided; —a reference target gazing step during which the individual gazes at the reference target; —a peripheral target providing step during which a peripheral target comprising a visual and auditory target is provided; —a peripheral target gazing step during which the individual gazes at the peripheral target; and, —a rotation measurement step during which the angle of rotation of the individual's head and the angle or rotation of the individual's eyes are measured.
