Controlling controllable device during performance

摘要

The at least one node (106, 108, 110) and a trackable tag (104) perform communication with each other. The tag (104) is associated with a person (112) belonging to a performance. A place of each controllable device (102) is known. The controller (100) receives position data of the trackable tag (104) and controls at least one controllable device (102) to direct with respect to the tag (104) on the basis of the position data and the place of the at least one controllable device (102) for causing an audio and/or optical operation associated with the performance to take place by the at least one controllable device (102).
