Abstract

The invention provides an operation right interlinking method and a cooperative working method wherein, when a plurality of shared application programs operate cooperatively with each other to effect a cooperative work, operation rights of the shared application programs are always possessed by a same terminal so that a work can be performed efficiently without an inconsistency. To this end, the operation rights of the shared application programs are controlled in an interlinking relationship with each other. When a request for an operation right is issued to a first application program of a first terminal, the first application program requests a first application program of a second terminal for transmission of the operation right and sends an operation right change notification to a second application program of the first terminal whose operation right is to be interlinked with the first application program. Upon reception of the operation right change notification, the second application program of the first terminal requests a second application program of the second terminal based on the operation right change notification.
