摘要

A line of sight detection device includes: a measurement unit that measures a movement of eyeball of a subject wearing eyeglasses; a gaze point detection unit that detects a gaze point of the subject in a forward field of view of the subject based on a result of measurement by the measurement unit; a transmission point detection unit that detects a transmission point at which a line of sight of the subject toward the gaze point passes through a lens of the eyeglasses based on the result of the measurement by the measurement unit; and a display control unit that causes gaze point information indicating a position of the gaze point to be displayed at a display in superimposition on an image of the forward field of view and causes transmission point information indicating a position of the transmission point to be displayed at the display in superimposition on a lens image showing the lens of the eyeglasses.
