Next, when a preset user's gesture is sensed (S20), contact point coordinate data that meets the display surface of the electronic device through the gesture of the user is calculated using the calculated three-dimensional coordinate data through the touch position calculating unit 330 (S30). In this case, the gesture sensed may be a motion of a predetermined user body or a pointer held by the user, for example, up, down, left, right, front, Not a gesture of the user, but also a voice.

Then, in step S40, information corresponding to the calculated contact point coordinate data is selected and information according to pointing for selecting other electric devices and performing the set operation is generated.

Then, the central server 200 calculates the electric devices indicated by the user on the basis of the generated pointing information, and allocates the selected electric devices to each other (S50). After that, the central server 200 allocates the contents selected by the assigned first device 101 (Moving, copying, separating, expanding, deleting, playing) the content to the second device 102 (S60).
