In a case where an actual object is moved by a user manipulation or by other means, physical phenomena associated with the object are addressed. A control system includes a mobile apparatus being an apparatus that moves on a sheet where images indicating coordinates are arranged and having a camera for photographing part of the sheet. The control system acquires the user manipulation, controls the mobile apparatus in such a manner as to travel according to the user manipulation (S106), detects a position of the mobile apparatus on the basis of an image photographed by the camera included in the mobile apparatus (S101), determines, on the basis of the position detection by position detection means, whether or not the mobile apparatus has moved in a manner estimated on the basis of the user manipulation (S102, S105), and performs a predetermined procedure (S103, S110, S111) in a case where it is determined that the mobile apparatus does not move in the estimated manner.
