Vigilance is an important skill for all surgeons to have. However, vigilance can be better described as a habit than a technical skill that can be taught.  

In this project, we used the Tobii Glasses to track the eye motions of novices while performing a cholecystectomy operation using a hybrid pig liver model.

He showed the eye motions of an expert to the experimental group to determine if eye-tracking can be used to teach vigilance.
