The Walls Have Eyes

A visualisation of how our data is captured

Three innocuous-looking picture frames, originally placed strategically around the Ethical Dilemma Cafe at Mozilla Festival 2014. Each frame collects pictures of people nearby and information from their phones. The pictures and data are displayed on a projector and printed using a dot-matrix printer, giving the invisible information leaking from our devices noisy physical form. These technologies are used by companies to track people for commercial purposes. BBC R&D created the installation as part of wider work investigating the costs and benefits of personalisation of media.
