VISUAL LINE MOVEMENT-RELATED VALUE ACQUISITION DEVICE, TRANSPORT APPARATUS EQUIPPED WITH SAME, AND VISUAL LINE MOVEMENT-RELATED VALUE ACQUISITION METHOD

摘要

The purpose of the present invention is to obtain a configuration with which the effective field of view of a person can be detected. A visual line movement-related value acquisition device 220: acquires a subject visual line movement-related value relating to the movement of a subject's visual line; acquires a coordinated motion-related value relating to a coordinated motion of the subject's eye motion and head motion with respect to the subject visual line movement-related value that has been acquired; and, from the relationship between the subject visual line movement-related value relating to the movement of the subject's visual line that has been acquired and the coordinated motion-related value relating to the coordinated motion of the subject's eye motion and head motion that has been acquired, outputs the subject visual line movement-related value relating to the movement of the subject's visual line when the coordinated motion-related value relating to the coordinated motion of the subject's eye motion and head motion is a predetermined value.
