Revealing team cognition from dual eye-tracking in the surgical setting

Surgery is a team effort. In this video, we display how we record two surgeons’ eye motions during a simulated surgical operation, then performed Cross Recurrence Analysis (CRA) on the dual eye-tracking data to develop a valid technology to assess shared cognition. Twenty-two dyad teams were recruited to perform object transportation task using laparoscopic techniques. Outputs from CRA, including overlapping, recurrence rate and phase delay were correlated with team performance measured by the task time, errors made, and movement de-synchronization. Gaze behaviors between the two team members recorded in the surgical videos correlated positively with team performance. Elite teams were overlapping gaze more with higher recurrence rate than the poor teams. Dual eye-tracking analysis can be a useful tool for assessing team cognition and evaluating the team training. • Human-centered computing ~ Interaction design – Systems and tools for interaction
