Abstract: Systems and methods are provided for computing gaze. The systems and methods access an uncorrected gaze vector computed based on a center point of a pupil of a user. The systems and methods process an image of the pupil by a machine learning model to predict an estimated error in a gaze vector, the machine learning model trained to establish a relationship between a plurality of ground truth gaze vectors and uncorrected gaze vectors for a plurality of pupil parameters, the pupil parameters including diameters, gaze angles, or gaze eccentricities. The systems and methods generate a corrected gaze vector by applying the estimated error in the gaze vector predicted by the machine learning model to the uncorrected gaze vector that has been computed based on the center point of the pupil of the user.
