Beyond Words: The Impact of Eye-Gaze Sharing on Collaboration and Cognitive Load
Chakraborty, Suvodip; Kiefer, Peter; Raubal, Martin (2025)
International Journal of Human-Computer Interaction
Distributed cognition systems rely on collaboration among decision-makers to address complex problems that are challenging for a single individual. The success of collaborative decision-making hinges on effective communication, enabling stakeholders to develop a shared understanding of both the scenario and the decision-making process. However, traditional decision support systems still predominantly rely on verbal communication, which tends to lose efficacy as cognitive load increases. This study aims to leverage gaze-sharing to enhance collaboration under high cognitive load conditions. We used a gamified N-back task to test across three communication conditions: speech-sharing, gaze-sharing, and a hybrid approach combining both gaze-and-speech sharing. Results, including NASA-TLX workload scores and pupil size measurements, reveal that the real-time gaze-sharing condition leads to lower cognitive load and lower reaction times compared to speech or the hybrid approach, particularly as task difficulty increases.
