In this paper, I present a field study conducted with interactive projections deployed to an urban art festival and designed to give audio-visual feedback in response to audio input from the public. I describe the context for the study, the spatial layout of the urban space used, the methodology adopted, and the results of my observations of 900 people visiting the work over 5 days. Based on the results, I derive a series of insights about the utilization of audio-based interactive projections in public spaces, notably in regards to: making passers-by aware of the interaction; the placement of the microphones relative to the projections; the impact of the spatial layout of the urban precinct on participation; and pitfalls to avoid regarding the visual elements existing at or introduced to the urban space.
