On the Design of deformTable: Atending to Temporality and Materiality for Supporting Everyday Interactions with a Shape-Changing Artifact

HCI research on shape change has highlighted the importance of materiality and temporality in design practice. However, little research has addressed the challenges of tailoring these qualities for everyday interactions with a shape-changing artifact. In this paper, we report from a designer-researcher perspective into the crafting of deformTable: a shape-changing form that responds to the weight of objects placed on its surface. We crafted 5 deformTables over 18 months with special attention given to the physical, temporal, and computational aspects. Specifcally, we describe how we focused on speed adjustments and response times in the process to frame the temporal expressions of computing; we also discuss how the material and tools helped shape our decisions in the context of the materiality of computing. This study contributes an RtD case of designing a particular shape-changing artifact through the lens of temporality and materiality to support long-term engagements and everyday interactions.
