Title
(EN) OCULAR OBSERVATION METHOD AND DEVICE, AND BIOMETRIC APPLICATION
(FR) PROCÉDÉ ET DISPOSITIF D'OBSERVATION OCULAIRE, ET APPLICATION BIOMÉTRIQUE
Abstract
(EN)
The invention relates to an ocular observation method, comprising presenting to an eye of a subject a light stimulus having color variations over time, and measuring changes in the pupil diameter of the eye of the subject in response to the light stimulus. The method produces a profile indicative of changes in the pupil diameter as a function of the color of the light stimulus.
(FR)
Le procédé d'observation oculaire, comprend la présentation à un œil d'un sujet d'un stimulus lumineux ayant des variations de couleur au cours du temps, et la mesure de variations du diamètre pupillaire de l'œil du sujet en réponse au stimulus lumineux. Le procédé produit un profil indicatif des variations du diamètre pupillaire en fonction de la couleur du stimulus lumineux.
