Effects of visualizing uncertainty on decision-making in a target identification scenario
Twenty-two experienced air traffic operators analyze spatio-temporal data with or without uncertainty visualizations. Target identification and prioritization tasks were conducted under high time-pressure and high cognitive load. Test group (with uncertainty visualization) needed significantly fewer attempts to make a final identification. Test group selected higher priority values and more hostile and suspect identities, without more workload or average time. No significant difference was observed regarding performance or expressed confidence in the decisions.
