Remote collaboration is a challenge for physical product designers, and especially limits the mutual communication of the "thinking through prototyping" approach. Inspired by the NURBSforms and self-shape sensing technologies, we investigate how to support remote co-design with a conceptual modular shape-changing interface toolkit. By using stop-motion videos and low-fi non-electronic prototypes as probes, the concept was evaluated through on-line questionnaires and workshops. The result shows its potential especially in the exploration phase of remote co-design. CCS CONCEPTS• Human-centered computing → Haptic devices; User centered design.
