Collaborative eye tracking: a potential training tool in laparoscopic surgery

Background Eye-tracking technology has been shown to improve trainee performance in the aircraft industry, radiology, and surgery. The ability to track the point-of-regard of a supervisor and reflect this onto a subjects’ laparoscopic screen to aid instruction of a simulated task is attractive, in particular when considering the multilingual make up of modern surgical teams and the development of collaborative surgical techniques. We tried to develop a bespoke interface to project a supervisors’ point-of-regard onto a subjects’ laparoscopic screen and to investigate whether using the supervisor’s eye-gaze could be used as a tool to aid the identification of a target during a surgical-simulated task.
