Abstract
Aspects of the present disclosure relate to eye tracking systems and methods which track eyes by illuminating the eyes using a light source and detecting the eye illuminations using a sensor. Implementations of the present disclosure may utilize a light source with a dynamic lighting position to account for changes in lighting conditions during the tracking which interfere with detection of the eye illuminations, such as reflections in glasses which may obscure a user's eyes.
