DISPOSITIF D'ACQUISITION DE VALEUR LIÉE AU MOUVEMENT D'AXE LIGNE VISUEL, APPAREIL DE TRANSPORT ÉQUIPÉ DE CELUI-CI, ET PROCÉDÉ D'ACQUISITION DE VALEUR LIÉE AU MOUVEMENT D'AXE LIGNE VISUEL

摘要

A structure in which an effective visual field of a person can be detected is achieved. A visual-line-movement-related-value-acquisition device acquires a subject's visual line movement-related value related to a visual line movement of a subject, acquires a coordinated motion-related value related to a coordinated motion of eye motion and head motion of the subject for the acquired subject's visual line movement-related value, and outputs the subject's visual line movement-related value related to the visual line movement of the subject when the coordinated motion-related value related to the coordinated motion of the eye motion and the head motion of the subject is a predetermined value from a relationship between the acquired subject's visual line movement-related value related to the visual line movement of the subject and the acquired coordinated motion-related value related to the coordinated motion of the eye motion and the head motion of the subject.
