Decisive design: how spatial arrangements shape group decision-making

This paper examines how spatial arrangements affect digitally supported individual and group decision-making. In a controlled within-subjects study, 24 participants completed the NASA Moon Survival Task across three spatial conditions: standing at an interactive table, sitting at the same table with personal zones, and using laptops. By analysing decision quality, speed, and perceived collaboration, the study shows that spatial design meaningfully shapes decision performance, interaction dynamics, and user experience.
