SENSOR is a new multi-media, interactive exhibition of works from an international mix of activists, philosophers, software engineers and artists. Their work brings the use of unmanned aerial vehicles, UAVs or “drones”, by the U.S., over the past thirteen years, to a tangible reality. The technology, implemented 8,000 miles away and officially unacknowledged by the CIA, is the future of warfare and military intelligence. Closer to home, drones patrol the southern border, and police forces look to adapt military surveillance technology in U.S. cities. This group of artists and engineers mine the issues and facts surrounding these controversial machines, their use here and overseas, and future implications.
