Seamful Design and Ubicomp Infrastructure

In this paper, we discuss taking a ‘seamful’ design approach to ubicomp systems. Some features that we designers usually categorise as infrastructure problems may, to users, be useful interactional features. Examples include the edges and gaps in 802.11 coverage, and the patterns of where one can and cannot get GPS positioning. Sometimes we cannot smooth over or hide these ‘seams’. Seamfulness is about taking account of these reminders of the finite and physical nature of digital media. Seamful design involves deliberately revealing seams to users, and taking advantage of features usually considered as negative or problematic. We outline the origins of the seamful approach, offer two examples of seamful design, and finally discuss potential approaches to ‘design for appropriation’ whereby user activity drives infrastructural adaptation.
