Abstract
Provided is a face-to-face situation determination system in which a first beacon, which is a beacon carried by a first user, transmits a first signal including information identifying the first beacon. A second beacon, which is a beacon carried by a second user, upon receiving the first signal from the first beacon, transmits, toward a control device, a second signal including information identifying the first beacon, a first signal reception intensity, and information identifying the second beacon. The control device receives the second signal and, on the basis of the first signal reception strength included in the second signal, determines that the first user and the second user are facing each other if the first signal reception strength is greater than or equal to a first threshold value for a predetermined period or longer, and determines that the first user and the second user are facing one direction.
