Challenges in Head-Free Eye Tracking in Health & Disease

Illustration of an eye ball with labeled pupil and visual tracking line, relevant to eye movement simulation research at SKERI.

This project is focused on investigating sources of error and potential improvement methodologies for head-free eye tracking, particularly in individuals with known oculomotor deficits.
