The Prudent Avoidance Device consists of a sensing apparatus worn by a participant, and a data modeling and web broadcast system for data analysis and presentation. The sensing device detects exposure to a wide range of electro-magnetic frequencies in the Extremely Low Frequency (ELF) range that are suspected of having harmful effects on human life. In laboratory and field studies, the health effects of these frequencies have not been proven to be either benign or dangerous; thus, national and international regulating agencies have suggested “Prudent Avoidance” of them for individuals. Without knowledge of where they exist and how they are dispersed, however, such avoidance becomes impossible.

To help make such effects more evident, the Prudent Avoidance Device collects a variety of information on exposure durations and frequency levels that are then correlated with a user’s physical location. The data is subsequently uploaded to a publicly accessible website and presented as a kind of interactive ‘documentary.’ Visitors to the web site are able to follow the lives of the participants (represented by images, geographically mapped exposure data, and correlations of exposure levels with international standards) as they navigate a public space filled with ELF emissions. As the prototype is advanced, we desire to make the device sharable, and collect these ‘data-driven’ narratives from multiple participants. In this way, the website will act as a repository of these logged testimonials, allowing visitors to even situate their own spatial experiences within the context of the represented data and better understand the collective impact of this invisible phenomenon.
