Abstract
Interruptions can disrupt coordination and reduce decision accuracy in complex systems. Recovery from interruptions is often affected by the difficulty of the task at hand, making it critical to design support tools to support users. One such tool is gaze sharing—visualizing a teammate’s gaze through on the other teammate’s screen. This study examines the role of user-controlled gaze sharing in supporting interruption recovery across task complexities. Eighty-four participants (42 teams) completed simulated UAV command and control tasks under three gaze sharing conditions—off, on, and user-controlled toggle—and two task complexity levels—simple and complex. Results revealed that gaze sharing improved post-interruption decision accuracy, with user-controlled gaze sharing providing the greatest performance benefit in complex tasks. These findings suggest that adaptive gaze sharing mechanisms can support effective coordination following interruptions. The study advances understanding of how gaze-based tools can inform the design of collaborative technologies for interruption-heavy team environments.
