The Suspect Backpack is a wearable mobile sonic media art experience providing an individual user with the opportunity for first-person interaction and engagement.

Intended for use in public space, members of the public become an unwitting audience, meanwhile creating a personalised and intimate environment for the individual user. Proximity between individual (user) and public (audience) is explored while inevitable shifts in distance alter the resultant audio heard by the user (on headphones) and the public (on portable speakers). The two sonic experiences concentrate on social anxiety (for the headphone user) and "fear of the other" (for the public audience), arousing suspicion about a potential terrorist threat.

Based on the case of David Mery and his subsequent research on profiling, the Suspect Backpack is designed to blend into a crowd. Using an ordinary backpack with "protruding wires", curiosity and possible concern are only raised when members of the public move close enough to see the exposed cables or are within audible range.
Technology implemented in this work includes sonar proximity sensors, an Arduino microcontroller, headphones and speakers plus small laptop running a MaxMSP patch.
