Stop and Smell the Chalk Flowers

摘要

HCI researchers have begun to more systematically study non-digital transient approaches for displaying information in public space, for example, in the form of chalk infographics. These approaches provide several benefits compared to digital displays, such as: ad-hoc deployment, barrier-free interaction, and being more sustainable. However, one limitation is their hyperlocal scale and impact. Speculating on urban robots as agents for scaling up physicalised displays, we describe the exploratory design and deployment of Woodie, a slow-moving robot that draws on the ground using conventional chalk sticks. We deployed Woodie for three weeks in a quiet laneway situated within a highly urbanised area. Data collected from observations, video logs and interviews revealed that Woodie successfully attracted people's attention and acted as a facilitator for collaborative, creative placemaking. Furthermore, Woodie provoked emotional responses and was perceived as a living being. Findings are interpreted to describe opportunities urban robots provide for the design of future pervasive urban displays.
