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.
Core Innovation
The invention provides an eye-tracking system for measuring eye tracking in a patient while identifying the patient. Patient identity is confirmed by capturing ocular biometric identifying information from the patient and matching it with a record of biometric data in a biometric matching engine and database.
The system includes a head rest assembly for stabilizing the patient’s head, an operator console for receiving user inputs, a stimulus screen for displaying a video to the patient, and an eye tracking camera on the head rest assembly. It further includes an ocular biometric capture device coupled with the head rest assembly, and a central processing unit for controlling the stimulus screen and performing data processing and other functions.
Eye tracking is performed during video display by tracking movement of the patient’s eyes via the eye tracking camera, and the captured ocular biometric identifying information is processed and compared with stored biometric data to confirm patient identity through the biometric matching engine and database. In additional workflow embodiments, a computer processor generates a score representing an ability of the patient’s eyes to track the video, and the method includes adjusting a vertical height of the head rest assembly and displaying a video on the stimulus screen according to a video selection made by the patient.
Claims Coverage
The independent claims cover two aspects: a system that measures eye tracking and identifies the patient using ocular biometric matching, and a method that adjusts the head rest, displays a selectable video, tracks eye movement, generates an eye-tracking ability score, and confirms identity by matching ocular biometric data with a record in a biometric database. Across the independent claims, four inventive features are central.
Head-rest stabilized eye tracking with stimulus display
A head rest assembly for stabilizing the patient's head; a stimulus screen on the headrest assembly for displaying a video to the patient; an eye tracking camera on the headrest assembly; an ocular biometric capture device coupled with the headrest assembly for capturing the ocular biometric identifying information from the patient; and a central processing unit for controlling the stimulus screen and performing data processing and other functions of the system.
Ocular biometric identification via biometric matching engine and database
A biometric matching engine and database in communication with the central processing unit for matching the captured ocular biometric identifying information with a record of biometric data.
Video selection and vertical height adjustment of head rest
Adjusting a vertical height of a head rest assembly of an eye tracking system; displaying a video to the patient on a stimulus screen on the head rest assembly of the eye tracking system, according to a video selection made by the patient.
Eye tracking ability score generation and patient identity confirmation by matching ocular biometric data
Tracking movement of the patient's eyes during display of the video via an eye tracking camera on the head rest assembly of the eye tracking system; capturing ocular biometric identifying information from the patient with an ocular biometric capture device coupled with the head rest assembly of the eye tracking system; generating, with a computer processor of the eye tracking 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, by matching the captured ocular biometric identifying information with the record of biometric data.
The claims collectively cover an integrated eye-tracking setup that stabilizes the patient, displays a video, measures eye tracking, captures ocular biometric identifying information, generates a score representing tracking ability, and confirms identity by matching the captured ocular biometric information against stored biometric records using a biometric matching engine and database.
Stated Advantages
Enables patient identity confirmation during eye tracking by matching captured ocular biometric identifying information with records of biometric data.
Provides a score representing an ability of the patient's eyes to track the video.
Documented Applications
Measuring eye tracking in a patient while identifying the patient by capturing ocular biometric identifying information and matching it with stored biometric data.
Eye-tracking workflow that displays video to a patient and uses eye-tracking and ocular biometric capture to generate an eye-tracking ability score and confirm identity.
