MoLux is a shape-changing lamp designed to address some of the grand challenges in shape-changing interfaces (SCI). This includes the challenges of understanding the user experience, integrating interaction into the artefact, and conducting in-situ comparative studies with SCI. MoLux uses bi-directional and direct interaction, deploys shape-change for input and output, and enables manipulation of two independent shape-changing parameters. Through an in-situ study, we investigated how users experienced living with MoLux over four days. The study compared three different interaction paradigms; direct, indirect, and negotiated control. Our findings reveal that most users preferred negotiated interaction as well as enjoyed living with the shape-changing lamp. Our results further contribute some methodological lessons and implications for designing SCI for the home.
