Eye Tracking System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18493482 titled 'Eye Tracking System

Simplified Explanation

The abstract describes an eye tracking system for detecting the position and movements of a user's eyes in a head-mounted display (HMD). The system includes an eye tracking camera, an illumination source that emits infrared light towards the user's eyes, and diffraction gratings located at the eyepieces. The diffraction gratings redirect or reflect a portion of the infrared light reflected off the user's eyes, while allowing visible light to pass. The cameras capture images of the user's eyes from the infrared light that is redirected or reflected by the diffraction gratings.

• Eye tracking system for head-mounted displays
• Includes eye tracking camera, illumination source, and diffraction gratings
• Gratings redirect or reflect infrared light from user's eyes
• Cameras capture images of user's eyes using redirected or reflected infrared light

Potential Applications

Original Abstract Submitted

An eye tracking system for detecting position and movements of a user's eyes in a head-mounted display (HMD). The eye tracking system includes at least one eye tracking camera, an illumination source that emits infrared light towards the user's eyes, and diffraction gratings located at the eyepieces. The diffraction gratings redirect or reflect at least a portion of infrared light reflected off the user's eyes, while allowing visible light to pass. The cameras capture images of the user's eyes from the infrared light that is redirected or reflected by the diffraction gratings.
