摘要

The present invention causes an appropriate controlled device to execute an operation, without specifying the controlled device. A linkage system (7) includes: a linkage server (1); a device control server (2) which, if an execution instruction for an operation pursuant to a linkage rule is received from the linkage server (1), transmits an operation execution command to a device (4) identified in accordance with a user prescribed by the linkage rule; the device (4); and an information provision server (5) which transmits the operation triggering information to the linkage server (1).
