PROBLEM TO BE SOLVED: To improve advertisement effects by means of presentation generator devices while preventing a plurality of presentation generator devices from being interfered with each other.SOLUTION: If a duration time of a standby state where a variation performance is not executed becomes equal to or longer than a predetermined time, a presentation generator device 202B is made movable from an origin position to a predetermined position as shown in (b). If the variation performance is started while the presentation generator device 202B is located at the predetermined position under the standby state or the presentation generator device 202B is made movable between the origin position and the predetermined position, the presentation generator device 202B is returned to the origin position. An execution pattern of the variation performance includes an execution pattern accompanied with movability of a presentation generator device that is different from the presentation generator device 202B and if the presentation generator device 202B is not located at the origin position when starting the variation performance, the movability of the other presentation generator device capable of interfering with the presentation generator device 202B is restricted. |
