A project by neoanalog.io was a part of the exhibition Photographs in Dialogue at the Etihad Museum, Dubai. The 40 foot-long interactive media wall depicts the history, from the 1950s to 1970s, of the UAE in images. In its default state, the wall consists of 31 tiny photo strips. Multiple optical sensors detect the positions of the people in the room. By this means, each of the strips can be triggered by visitors if they stop in front of it. The strip then unfolds, unveiling the entire photo with a short description providing historical context. Our part in this project was the creation of the software, the logic behind the algorithm, which is responsible for reading and analyzing the sensor data and opening the right strip at the right moment.
