The present invention has been made to allow a user to easily grasp the operation area and thereby to easily and quickly perform the operation even in the case where the operation area extends across the entire system. An operation guidance display unit displays the entire appearance of a system to be operated as well as displays the operation position, in a specific manner, relative to the entire appearance of the system to thereby provide guidance of the operation position in the entire system and further displays, in an enlarged manner, the operation method related to the operation position displayed in a specific manner to thereby provide guidance of the operation method.
