What chalk and tape can tell us: Lessons learnt for next generation urban displays
In recent years, many researchers have explored the different roles public displays can play in the urban environment. A particular focus has been on the deployment of digital screens. A range of technical, spatial and social factors have been found to influence the appeal, acceptance and usage of such screens. As there are still a range of unsolved issues around digital screens, including display blindness and evaluation apprehension, we argue that when thinking about the design of next generation urban displays, it is important to not only focus on these digital screens. Instead, we propose also investigating other types of displays, including non-digital ones. We contribute to this evaluation of a wider range of public displays by presenting two case studies in which non-digital public visualisations of local data were deployed in urban communities. Based on the findings from these studies, we distinguish four affordances of non-digital public displays and describe the opportunities these reveal for the design of future urban displays.
