Actuating, dynamic materials offer substantial potential to enhance interior designs but there are currently few examples of how they might be utilised or impact user experiences. As part of a design-led exploration, we have prototyped (Wizard-of-Oz) an actuating, dining table runner (ActuEater1), and then developed a fully-interactive fabric version that both changes shape and colour (ActuEater2). Four in-situ deployments of ‘ActuEaters’ in different dinner settings and subsequent ‘design crits’ showed insights into how people perceive, interpret and interact with such slow-technology in interesting (and often unexpected) ways. The results of our ‘ActuEating’ studies provide evidence for how an actuating artefact can be simultaneously a resource for social engagement and an interactive decorative. In response, we explore design opportunities for situating novel interactive materials in everyday settings, taking the leap into a new generation of interactive spaces, and critically considering new aesthetic possibilities.
