LINE-OF-SIGHT MEASUREMENT SYSTEM, LINE-OF-SIGHT MEASUREMENT METHOD, AND PROGRAM

摘要

This line-of-sight measurement system is equipped with: a user imaging unit that can be worn by an observer moving in a display space in which observation subjects are displayed, and that captures an image of the field of view in front of the observer; a user line-of-sight measurement unit that can be worn by the observer, and that acquires line-of-sight measurement data indicating the direction of the line of sight of the observer in a coordinate system for the field-of-view image; and a line-of-sight measurement device that determines a gaze location toward which the observer is gazing in the display area, on the basis of a coordinate position at which there is an intersection between three-dimensional shape data of the display space in which the observation subjects are displayed and a line-of-sight direction vector of the observer in the display area, said vector being determined from the line-of-sight measurement data.
