Visualising Things. Perspectives on How to Make Things Public through Visualisation

In this paper, we will be discussing how visualisations can facilitate participatory processes by way of conveying issues of public concern as ‘things’. In the line of Latour’s plea to ‘make things public’ (Latour and Weibel, 2005), visualisations can be purposefully designed to trigger and encourage public debates concerning a wide range of issues. For this, we explore how a visualisation can be both transparent (i.e. visualising the complex entanglement of backstories of an issue) and readable. Specifically we clarify the aspect of designing a readable visualisation of ‘things’. First, drawing from different fields of literature (i.e. Information Visualisation, Science, and Technology Studies and Human-Computer-Interaction) we will articulate three main aspects of readability: engaging people to interact with a visualisation of complex issues, supporting sense making and encouraging reflection. Then, based on three empirical case studies, we indicate different design considerations in terms of engaging people to interact with a visualisation: contextualising a visualisation (via its location or medium), staging interaction and allowing people to provide their own perspective on the issue displayed. As a conclusion we propose a scenario that allows the visualisation to gradually become more transparent in support of its readability.status: publishe
