British artist, teacher and cultural activist Christian Nold has assembled an amazing technology project called BioMapping.net, which combines a global positioning system receiver, a galvanic skin sensor that crudely determines emotional response, and Google Maps to render ‘emotional maps’ that correlate a person’s emotional state and their physical location as they journey through a landscape. The result is an individual, emotional narrative of place.

Nold is using the technology to create a massive emotional map of Greenwich, England. As more and more people use the technology, a map of emotional ‘hot spots’ emerges. One can imagine taking a “chilled out” tour, avoiding all of the ‘maximally excitable’ locations, or an inverse “freak out” tour of panic-inspiring locations.
