Sensor 50 has one or both of wearable sensor 51 and tracking sensor 52 . The wearable sensor 51, which is the first sensor, is a sensor that detects movements of the spectator's body (fingers, arms, head, legs, waist, entire upper body, etc.). In the present embodiment, the first sensor is, for example, a sensor attached to a detection target such as an arm of a target audience, but is not limited to this form. For example, it may be a sensor worn by a performer on the stage 40 or a staff who manages the venue A, as long as it can detect the movement of the detection target. Wearable sensor 51 is used, for example, for hand tracking.

For example, the determination unit 152 determines the movement direction of the audience's body (body, head, arms, legs, etc.) from the data detected by the first sensor. Then, the output control unit 153 controls the lighting equipment 20 so as to illuminate the direction in which the audience faces. For example, the output control unit 153 changes the direction of the light emitted from the lighting device 20 in the direction in which the body of the audience faces. Further, for example, the output control unit 153 controls the lighting of the lighting fixtures 20 positioned in the direction in which the body of the audience faces. Further, for example, the output control unit 153 controls the lighting of the lighting fixtures 20 included in the area positioned in the direction in which the body of the audience faces.

Further, for example, the determination unit 152 determines the timing of movement of the spectator's body (body, head, arms, legs, etc.) based on detection data from the first sensor. Then, the output control unit 153 controls the lighting equipment 20 in accordance with the timing at which the body of the audience is turned. Here, the timing determined by the determination unit 152 is, for example, the timing when the audience raises their hands or the timing when they raise their heads in headbanging. Then, the output control unit 153 blinks and controls the lighting device 20 so that the lighting device 20 is turned on at a predetermined timing (for example, the timing when the hand is raised or the timing when the head is raised).

Further, for example, the determination unit 152 determines that the audience's body (body, head, arms, legs, etc.) is not moving, based on the data detected by the first sensor. Then, the output control unit 153 controls the lighting equipment 20 because the audience's body is not moving. For example, the output control unit 153 controls lighting of the lighting fixtures 20 so that the lighting fixtures 20 are turned off when the spectator's body is not moving.

The tracking sensor 52, which is the second sensor, is a sensor that monitors the lighting environment including the spectators to be detected and detects the movements of the spectators. The tracking sensor 52 is installed, for example, on a wall, floor, ceiling, or the like. The tracking sensor 52 detects a spectator as a detection target, and detects the movement of the detected spectator. The tracking sensor 52 may be, for example, an image sensor that captures the lighting environment.

For example, from the data detected by the second sensor, the determination unit 152 determines the movement direction and timing of the audience's body (body, head, arms, legs, etc.). Further, the output control unit 153 controls the lighting fixtures 20 in accordance with the movement direction and timing of the audience's body determined by the determination unit 152 . The wearable sensor 51 and the tracking sensor 52 may have the same or different detection targets.
