• (d) operating a processor for controlling the camera and transmitting data to the software application running on each smartphone in the group to activate the lighting output of each smartphone,
• wherein the unknown position of any smartphones in a presentation is determined by:
• i) sending an initial data file to a first smartphone to activate a graphic on the first smartphone in the group;
• ii) obtaining visual feedback from the camera as to the position of that first smartphone in the group;
• iii) sending the correct data file based on the position of the first smartphone based on its position in the group for the display of the presentation across all the smartphones in the group;
• iv) sending an initial data file to a second smartphone to activate a graphic on the second smartphone in the group;
• v) obtaining visual feedback from the camera as to the position of the second smartphone in the group;
• vi) sending the correct data file to the second smartphone in the group based on its position in the group for the display of the presentation across all the smartphones in the group;
• vii) repeating the process for each smartphone in the group until all of the positions of all of the smartphones in the group have been sent the correct data file for the presentation across all the smart phones in the group.
