Toward a Webcam Based ITS to Enhance Novice Clinician Visual Situational Awareness

Abstract

This research focus specifically on the eye-gaze movement of novice vs. expert clinicians to perform their clinical reasoning. The eye gaze data are spatiotemporal sequences representing the dynamic of the clinician’s eye movements in the visual space to perform a clinical reasoning tasks. The objective is to do a comparative analyses of the eye movements fixations inside some areas of interest, the saccades trajectory and the scanpath. Taken together, the outcome of those analysis has provided us insights to build a webcam based ITS (Intelligent tutoring system). The aim of the ITS is to help reinforcing gradually the learning stages of novice clinicians with some cues from the behavioral implicit expert knowledge in terms of visual attention to perform a clinical reasoning in critical anesthesiology clinical case.
