Abstract

A notification system includes a seat; a luggage detection unit that detects a presence of luggage on the seat or in the vicinity of the seat, the luggage being held by a user; a seating detection unit that detects whether or not the user is seated on the seat; a notification unit that notifies the user of presence or absence information of the luggage; and a control unit that is connected to and controls the luggage detection unit and the notification unit. When the luggage detection unit detects the luggage after an elapse of a predetermined time from when the seating detection unit has detected that the user has left the seat, the control unit causes the notification unit to notify the user that the luggage has been detected.
