Abstract
Spatial interaction is typically designed around body-scale gestures, yet extended spaces provide a different perspective. In this work, we apply the Extended Thinking framework to analyze user-defined gestures for an extreme setting. Our findings, on the relationship between the scale of the environment and that of the human body, contribute insights for future spatial interaction design.
