Abstract: A position estimation system includes: an obtainer that obtains image information of an image showing an indoor space in which a person is located; an estimator that estimates the coordinates of the person in the indoor space, on the basis of the image information obtained; and a position information obtainer that obtains position information of a first communication device from a positioning system. The estimator estimates the coordinates of a target first communication device held by the person, based on the coordinates of the person estimated and the position information obtained, and estimates the coordinates of an object other than the person in the indoor space, on the basis of a state of communication between a third communication device held by the object and the target first communication device, and the coordinates of the target first communication device estimated.

Abstract: An airflow control system (10) includes: an obtainer (34) that obtains image data of an interior space (50) in which an airflow is formed by an airflow generation device (40) and a person is located; an identifier (35) that identifies skeletal coordinates of the person based on the image data obtained; an estimator (36) that estimates a movement of the person based on time-series data of the skeletal coordinates identified; and a controller (37) that controls the airflow generation device (40) to suppress a disturbance of the airflow caused by the movement of the person estimated.

Abstract: A lighting system includes a plurality of lighting devices and a control device. The plurality of lighting devices are installed in a facility. The control device controls the plurality of lighting devices. The control device controls lighting light projected by at least one lighting device, belonging to the plurality of lighting devices, into colored lighting light, of which a color is different from a color white, to give, upon acquiring information about an event in question, a sign depending on the event in question.
