EYE TRACKING FIXATION MONITORING SYSTEMS AND METHODS
Abstract: systems and methods for tracking eye movement during a diagnostic procedure include an eye tracker capturing images of an eye, and a control processor configured to detect an eye position and orientation in each of the images, determine an eye fixation position and orientation relative to an optical axis of the eye tracker, 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 the images to determine the eye position and orientation relative to the eye fixation parameters. the eye fixation parameters may comprise a reference position and orientation of the eye when fixated. a histogram is constructed of detected eye positions and orientations and analyzed to determine an eye fixation position and orientation.
