## Abstract

A method for measuring eye tracking in a patient and capturing ocular biometric identifying information from the patient may involve: displaying a video to the patient on a stimulus screen of an eye tracking and biometric identification system; tracking movement of the patient's eyes during display of the video via an eye tracking camera of the eye tracking and biometric identification system; capturing ocular biometric identifying information from the patient with an ocular biometric capture device of the eye tracking and biometric identification system; generating, with a computer processor of the eye tracking and biometric identification system, a score representing an ability of the patient's eyes to track the video; and confirming, with the computer processor, an identity of the patient, based on the captured ocular biometric identifying information.

## Claims

### Claim 1

A system for measuring eye tracking in a patient and capturing ocular biometric identifying information from the patient, the system comprising:
a stimulus screen for displaying a video to the patient;
an eye tracking camera;
at least one head rest member for stabilizing the patient's head, relative to the stimulus screen;
an ocular biometric capture device for capturing the ocular biometric identifying information from the patient; and
a system computer housed in the main column for controlling the stimulus screen, data processing and other functions of the system.
