Opportunistic engagement by designing on the street

Lightweight, opportunistic participatory design exercises in public spaces have the potential to collect large volumes of candid feedback and insights from members of the public. We motivate the need for ''designing on the street' in terms of the time and resource requirements of traditional participatory design methods, and begin the process of unpicking the conditions for success and practical requirements. We demonstrate through a pilot study that opportunistic participatory design can be a useful tool for addressing design challenges in everyday settings, where most people have some familiarity with the design area.
