A sonic spotlight beam to track individuals

Access, Marie Sester’s interactive work is accessible online throughout this year’s edition of Villette Numerique (in the “Zone de confluences” exhibition), next to Paris, on September 21 – October 3.


Access lets you track individuals in public places, by pursuing them with a robotic spotlight and acoustic beam system. The beam is either activated as people move through the space under surveillance, or it is piloted remotely using a Web interface. In either case, it is impossible for the target to escape the spotlight.

The tracked individuals do not know who is tracking them nor are they aware of being the only persons among the public hearing the sound.

ACCESS calls for awareness of the implications of surveillance, detection, celebrity, and their impact on society.
