    Abstract: A state detection device (100) detects a state of a driver driving an automobile (300), and includes: a first camera (110) that captures a face of the driver at a first frame rate; a. second camera. (120) that captures an environment in a forward direction of the automobile at a second frame rate;
    and a. processor (130) that processes images obtained from the first and second cameras (110, 120). The processor (130) calculates a :line-of-sight direction of both. eyes of the driver based on a face image obtained from. the first camera (110) and calculates a focal position of the driver based on the hue-of-sight direction. of both. eyes of the driver, and detects the state of the driver by determining the state of the driver based on the focal position and a forward image obtained from the second camera (120). The first frame rate is N times the second frame rate (N is an integer of 1 or greater),

    Abstract: A wakefulness inducing device includes: a heat dissipation intensity obtainer obtaining a user's heat dissipation intensity from a heat dissipation intensity sensor; and a controller controlling an air conditioner to alternate the user's heat dissipation intensity between a first heat dissipation intensity and a second heat dissipation intensity lower than the first heat dissipation intensity. The controller alternates the user's heat dissipation intensity by controlling the air conditioner based on the user's heat dissipation intensity to set a first time period longer than a second time period. In the first time period, the user's heat dissipation intensity increases from the second heat dissipation intensity to the first heat dissipation intensity, or remains at the first heat dissipation intensity. In the second time period, the user's heat dissipation intensity decreases from the first heat dissipation intensity to the second heat dissipation intensity, or remains at the second heat dissipation intensity.
