Claim 3:
4. A method for performing performance directing by controlling slave devices of audience located in each seat of a concert hall, comprising:
providing, via an information providing unit, emission position information corresponding to a seat position to the slave devices of the audience, wherein the emission position information includes predetermined information for grouping the slave devices to perform show directing; and
grouping, via a lighting control unit, the slave devices;
transmitting, via the lighting control unit, an emission control signal for controlling emission of the grouped slave devices for each group,
wherein the emission control signal includes control information for grouping and controlling the slave devices by one or more predetermined periods and an activation signal for each period for distinguishing the one or more periods,
wherein the control information includes group identification information for grouping the slave devices so that a boundary between the groups of the grouped slave devices constitutes an outline of image corresponding to the direction information for each section and lighting pattern information for each group of the grouped slave devices,
wherein the emission control signal is transmitted to the slave devices via a sub-master device,
wherein the emission control signal further includes a radio wave intensity value and an emission pattern value of a signal to be transmitted by the sub-master device to the slave devices; and
setting, based on the radio wave intensity value, a radius of a particular group of the slave devices to be controlled by the sub-master device; and
setting, based on the emission pattern value, a particular color to be emitted by the particular group of the slave devices.
