|Abstract:||This paper examines how a tangible interface facilitates gesture-mediated spatial reasoning during collaborative problem solving, as evidenced by sensitivity to emergent spatial patterns within a complex system simulation of a watershed. We tested the interface against two non-tangible input comparison conditions (single- and multi-mouse) to control for access differences. To determine if groups' solutions displayed sensitivity to emergent spatial patterns, we constructed a quantitative "dynamism" measure, and found that solutions produced in the tangible condition were significantly more spatially sensitive. To better understand why, we conducted a case study by selecting two representative participant groups and performing qualitative multimodal analyses of participant speech and gesture. Our findings indicate that the tangible interface's greater affordance of gesture allowed participants to express concepts containing both spatial and temporal properties, with the added benefit of increasing the agency of less-verbally participatory group members to explore and contribute their ideas more equitably.|
