CA 2525548

A device for promoting subject person~s awareness of a change of his/her posture, the awareness promoted by skin sensory stimulation produced based on posture change information (amount, direction, etc. of a positional change of subject person~s gravity center) from an apparatus for detecting a posture change of the subject person. The device has stimulation-producing means (vibrators) for producing skin sensory stimulation and stimulation-controlling means for driving the stimulation-producing means based on the posture change information. The control means has means for selecting vibrators, based on the direction of a positional change of the gravity center, from the vibrators arranged substantially parallel to the direction of a positional change of the gravity center, and sequentially drives the selected vibrators, for example, to the direction opposite the direction of a positional change of the gravity center. Further, the control means drives the vibrators so as to produce sensory stimulation with strength corresponding to the amount of a directional change of the gravity center. The vibrators are installed on a foot bottom, waist, breast, etc. The device can accurately inform the subject person of a change of his/her posture to promote his/her action to maintain the posture.

Cette invention concerne un dispositif favorisant chez une personne la prise de conscience d'un changement de posture, cette prise de conscience étant favorisée par une stimulation sensorielle de la peau produite par des informations sur un changement de posture (ampleur, direction, etc. du changement de position du centre de gravité de la personne) qui sont transmises par un appareil de détection de changement de posture. Le dispositif comporte un élément stimulateur (vibreurs) qui applique des stimulations sensorielles à la peau et un élément de commande de stimulation qui pilote le stimulateur en fonction des informations sur le changement de posture. L'élément de commande a la possibilité de choisir les vibreurs en fonction de la direction de changement de position du centre de gravité et de piloter séquentiellement lesdits vibreurs, par exemple dans la direction opposée à la direction de changement de position du centre de gravité. De plus, l'élément de commande peut agir sur les vibreurs de manière à doser la force de la stimulation sensorielle en fonction de l'importance du changement de direction du centre de gravité. Les vibreurs sont montés sous la plante des pieds, à la taille, sur la poitrine, etc. Le dispositif de l'invention permet d'informer avec précision la personne d'un changement de posture et de l'aider à conserver une posture adéquate.
