Abstract
(EN)
A system (10) for estimating a caution area with high accuracy independently of the mental state of the user. The system (10) comprises means (11, 17) for detecting the line of sight of the user, means (13, 21) for detecting bioinformation on the autonomic nerve system of the user, means (19) for estimating a line of sight stay model representing the degree at which the line-of-sight of the user stays in the field of view by analyzing the distribution of the line of sight of the user determined by the direction of the line of sight by using a statistical learning scheme, means (23) for estimating the arousal level on the basis of the bioinformation, and means (25) for estimating a caution area according to the parameter of the line-of-sight stay model and the arousal level.

L'invention concerne un système (10) pour estimer une zone à restrictions avec une grande précision, indépendamment de l'état mental de l'utilisateur. Le système (10) comprend des moyens (11, 17) pour détecter la ligne de visée de l'utilisateur, des moyens (13, 21) pour détecter des bio-informations sur le système nerveux autonome de l'utilisateur, des moyens (19) pour estimer un modèle de maintien de ligne de visée, représentant le degré auquel la ligne de visée de l'utilisateur se maintient dans le champ de vision, par l'analyse de la distribution de la ligne de visée de l'utilisateur déterminée par la direction de la ligne de visée, à l'aide d'un plan d'apprentissage statistique, des moyens (23) pour estimer le niveau d'éveil sur la base des bio-informations, et des moyens (25) pour estimer une zone à restrictions selon le paramètre du modèle de maintien de ligne de visée et le niveau d'éveil.
