Privacy Preserving Media Space is an experiment in how physical devices can mitigate privacy controls in always on video. The idea is that the video image sent to others is automatically blurred as people move away from the camera (detected by a proximity sensor), and that the camera itself will rotate to face the wall if someone 'blocks' the video by putting their finger over the lens (detected by simple image processing). Opposite actions return the system to normal.

Michael Boyle created this in a few hours as a rapid prototype that reflected ideas presented in Kuzuoka and Greenberg's Digital but Physical Surrogates paper.
