Eye tracking fixation monitoring systems and methods

A system comprising:

• an eye tracker configured to capture a first plurality of images of a current eye;
• and
• a control processor configured to:
• detect an eye position and orientation in each of the first plurality of images;
• determine an eye fixation position and orientation relative to an optical axis of the eye tracker by inputting the eye position and orientation of the eye in the first plurality of images into a neural network trained using a set of historical data to determine when a historical eye was fixating and to output a determination of the current eye fixation position and orientation relative to the optical axis, wherein the neural network is trained by constructing and analyzing one or more histograms of detected historical eye positions and orientations;
• estimate eye fixation parameters based at least in part on the determined eye fixation position and orientation;
• and
• track the eye position and orientation by analyzing one or more images from the first plurality of images to determine the eye position and orientation relative to the eye fixation parameters.
