Abstract:
1. A network system for remotely controlling a plurality of objects to be controlled including electric appliances, comprising: a video camera of which a field of view or a controlable range within the field is set to include said objects to be controlled and which detects only light of a particular wavelength region; a remote controller for generating electromagnetic waves toward a given position within said field of view or within said controlable range to form a light pointer of said particular wavelength range at said position irradiated with said electromagnetic waves, and capable of remote controlling; and a control unit that processes an output signal from said video camera to detect at least one, indicated by said pointer, of said objects to be controlled, receives from said remote controller an operation signal associated with the remote controlling on said indicated object, and supplies a control signal according to said operation signal through a network to said indicated object, wherein, when receiving said operation signal, said control unit detects an operational state of said indicated object by using a database storing operational states of said plurality of objects so as to determine the control signal for controlling said indicated object to operate according to said operation signal, so that said indicated object can be remotely controlled by said remote controller.
