This document summarizes a workshop about spatial interaction design and embodied understanding. It discusses how experts use the intelligent arrangement of space to extend memory, make sense of tasks, simplify choices and processes. It also discusses how understanding comes through interaction with representations that relate to the physical world and allow direct manipulation. Designing for collaboration and dynamic spatial modeling was presented as a way to activate the body for understanding complex systems. The workshop aimed to discuss using space to think and dynamic spatial models for sensemaking.
