to receive a vehicle exterior video including a visual target of a subject and a vehicle interior video including the subject, the vehicle exterior video and the vehicle interior video being captured by an imager, to measure a visual target movement of the subject using the vehicle as a fixed coordinate system from the vehicle exterior video, to measure a head movement of the subject from the vehicle interior video, and to estimate a reflexive eye movement of the subject;
to measure an eye movement of the subject from the vehicle interior video; and
to calculate an evaluation value for the reflexive eye movement from the estimated reflexive eye movement and the measured eye movement.
