Abstract:
The field of view of a video camera is set to include electric appliances such as a refrigerator, TV set, air conditioner and lamp installed within a room. When the user operates a remote controller to emit a visible laser beam toward a controlable range including these electric appliances set within this field of view, and designate a certain one of the appliances by the resulting pointer within the controlable range, the video camera for extracting only the visible laser beam of a wave length picks up this pointer, and a control box detects the position of the pointer within the controlable range from the output of the camera so that the appliance designated by this pointer can be detected and remotely controlled by use of the remote controller.
Abstract:
PROBLEM TO BE SOLVED: To provide a communication system which can speedily be connected to a device to be connected without regard to a changeover, and to provide a communication terminal and a communication method. SOLUTION: Since a device priority table T1 where priority is defined in accordance with a device that a user usually uses is stored in a remote controller 1, the system can speedily be connected to the device of high priority. Even if a key input processing is performed by connecting the system to the other device, connection is automatically restored to the device of high priority when the key input processing is not performed for prescribed time. Even if a plurality of connections are not simultaneously supported, a speedy operation is realized without permitting the user to be conscious of time lag for the key input processing.
