  • Patent number: 9872635
    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.

  • Publication number: 20170035339
    Abstract: A configurable system is used to evaluate stimulus sensitivity of a subject. An action channel provides a stimulus to the subject and a reaction channel receives a response from the subject. A signal pathway is connected to the action channel and to the reaction channel. A controller establishes loops within the signal pathway. Loop types include a transduction loop including the action channel and forming a path terminating in the signal pathway, and a channel loop including the action channel and terminating at a reference unit. Other possible loop types include an interface loop including the action channel, the reaction channel and the reference unit having an initial parameter value, and an adaptive loop including the action channel, the reaction channel and the reference unit whose parameter value is adapted based on the response from the subject. A method using the system is also described.

  • Patent number: 9389438
    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.

  • Publication number: 20150238083
    Abstract: There is described a probe device for optically investigating a tissue of a subject, comprising: a first probe element, a second probe element, and a third probe element each to be positioned at a respective vertex of a triangle for sensing the tissue, the first probe element each comprising a first light source for emitting light having a first wavelength, the second probe element each comprising a second light source for emitting light having a second wavelength and a first photodetector for detecting light having the first wavelength and scattered by the tissue, and the third probe element comprising a second photodetector for detecting light having the first and second wavelengths and scattered by the tissue.

  • Publication number: 20150230744
    Abstract: A method for assessing a subject perception of a stimulus property, comprising: applying to a subject at least a first sensory stimulus having a first value for the stimulus property and a second sensory stimulus having a second value for the stimulus property different from the first value; requesting the subject to identify a characteristic of the first and second sensory stimuli during the application thereof, the characteristic being unrelated to the stimulus property to be assessed, thereby focusing an attention of the subject on a decision making task; measuring an activity of at least one brain region of the subject during the application of the first and second sensorial stimuli and the identification of the characteristic thereof, thereby obtaining a brain activity measurement; and determining a difference of stimulus property perceived by the subject between the first and second sensory stimuli from the brain activity measurement.

  • Patent number: 8369955
    Abstract: The present invention relates to a method and a system for improving sensitivity of a first sensory, reflex and/or motor mechanism of a subject by stimulating a second sensory, reflex and/or motor mechanism of the subject. For that purpose a noise is applied to the second sensory, reflex and/or motor mechanism to improve the sensitivity of the first sensory, reflex and/or motor mechanism due to cross-modal SR interactions.
