- METHOD AND SYSTEM FOR COGNITIVE FUNCTION TESTING
Publication number: 20170049373
Abstract Cognitive function testing. At least some of example embodiments are methods including performing a cognitive function test on a patient without calibrating pupil position of the patient. The performing may include: causing a visual cue on a computer screen in front of the patient to move in a predetermined pattern; reading frames from an eye camera that captures images of an eye of the patient while the visual cue moves on the computer screen and the patient visually tracks the visual cue; determining pupil position within the frames; correcting offsets between the stimulus data and the pupil position data; translating the pupil position data from a coordinate space of the eye camera to a coordinate space of the stimulus data; and generating a test score being the cumulative distance between the stimulus data and pupil position data for each corresponding point in time.

- Correlating pupil position to gaze location within a scene
Patent number: 9292086
Abstract: Correlating pupil position to gaze location within a scene. Illustrative embodiments may include correlating pupil position of a user to gaze location within a scene viewed by the user. The correlating may include: illuminating an eye of the user, the eye containing the pupil, and the illuminating with light; creating a first video stream depicting the eye; creating a second video stream depicting the scene in front of the user; determining pupil position within the first video stream; calculating gaze location in the second video stream based on pupil position in the first video stream; and sending an indication of the gaze location in the second video stream to a computer system.
