A remote controller comprising: a communicator ; a sensor ; and a processor configured to: control the communicator to transmit an identification information request signal to a plurality of electronic apparatuses (200-1, 200-2, 300) paired with the remote controller, receive from two or more of the plurality of electronic apparatuses (200-1, 200-2, 300) a signal that includes identification information in response to the identification information request signal, identify an orientation state of the remote controller based on a direction from which each of the signals from the two or more of the plurality of electronic apparatuses (200-1, 200-2, 300) is received, perform communication via an exclusive communication channel between the remote controller and one of the plurality of electronic apparatuses (200-1, 200-2, 300) based on the identified orientation state, terminate the communication via the exclusive communication channel based on a detection by the sensor that a grip by a user of the remote controller and an orientation state of the remote controller are changed by more than a predetermined angle, and transmit the identification information request signal to the plurality of electronic apparatuses (200-1, 200-2,300). a communicator ; a sensor ; and a processor configured to: control the communicator to transmit an identification information request signal to a plurality of electronic apparatuses (200-1, 200-2, 300) paired with the remote controller, receive from two or more of the plurality of electronic apparatuses (200-1, 200-2, 300) a signal that includes identification information in response to the identification information request signal, identify an orientation state of the remote controller based on a direction from which each of the signals from the two or more of the plurality of electronic apparatuses (200-1, 200-2, 300) is received, perform communication via an exclusive communication channel between the remote controller and one of the plurality of electronic apparatuses (200-1, 200-2, 300) based on the identified orientation state, terminate the communication via the exclusive communication channel based on a detection by the sensor that a grip by a user of the remote controller and an orientation state of the remote controller are changed by more than a predetermined angle, and transmit the identification information request signal to the plurality of electronic apparatuses (200-1, 200-2,300). control the communicator to transmit an identification information request signal to a plurality of electronic apparatuses (200-1, 200-2, 300) paired with the remote controller, receive from two or more of the plurality of electronic apparatuses (200-1, 200-2, 300) a signal that includes identification information in response to the identification information request signal, identify an orientation state of the remote controller based on a direction from which each of the signals from the two or more of the plurality of electronic apparatuses (200-1, 200-2, 300) is received, perform communication via an exclusive communication channel between the remote controller and one of the plurality of electronic apparatuses (200-1, 200-2, 300) based on the identified orientation state, terminate the communication via the exclusive communication channel based on a detection by the sensor that a grip by a user of the remote controller and an orientation state of the remote controller are changed by more than a predetermined angle, and transmit the identification information request signal to the plurality of electronic apparatuses (200-1, 200-2,300). <EOS>
