In 2015–2016 the author installed interactive public artworks on sidewalks in Brooklyn and Queens using ordinary city permits. The locations were chosen in counterbalance to the dominant choices of location for public art in New York, which tends to be placed in Manhattan or other tourist-concentrated areas. The works are entitled the Public Utteraton Machines and enable passersby to utter their opinions about other public art in the city as well as art’s role in society. The device’s earpiece recorded over 100 open-ended narratives and 391 responses to quantitative data questions via an integrated e-paper display screen. This public art project combines social practice with object-based public art into a conceptual public art practice that forms a commons or civic art. Sound archives of the responses can be found at local libraries in Queens and Brooklyn and at http://utteraton.com/.
