Abstract: The present invention relates to a puzzle system capable of cooperating with an external device. More specifically, it relates to a puzzle system capable of cooperating with an external device, whereby a user's continuous interest can be stimulated by automatically detecting a type of puzzle that includes a plurality of puzzle pieces, and expressing various implementation operations corresponding to the puzzle when the puzzle is completed.

Abstract: Provided is a method for controlling multiple devices in an automatic interworking manner, by which the multiple devices are controlled, according to a set of operation mstoringodes including combined functions of the multiple devices, through one central control device without individually controlling the functions of each of the multiple devices. The method includes an operation mode setting step for setting an operation mode in which performable functions of the electronic devices are combined and performed in a specific order and for storing the set operation mode in the central control device, an operation mode selecting step for selecting an operation mode to be executed in a plurality of set operation modes, and a controlling step for controlling the electronic devices according to the selected operation mode.

Abstract: Disclosed is a device control method which makes it possible to more easily control a variety of devices in such a way to combine a variety of control commands provided to control the functions of each device for thereby controlling such devices. The device control method configured to control a main device and one or a plurality of auxiliary devices connected to the main device by way of a wired or wireless communication, comprises preparing a command assembly unit in the main device in such a way to combine a plurality of control commands used to control the functions that the main device or auxiliary device perform; and controlling the main device or the auxiliary device by way of the command assembly unit.
