EYE TRACKING SYSTEM WITH IN-PLANE ILLUMINATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329736 titled 'EYE TRACKING SYSTEM WITH IN-PLANE ILLUMINATION
Simplified Explanation: The patent application describes an eye tracking system for a near-eye display device that uses side-emitting LEDs to illuminate the user's eye and generate glints for tracking purposes.
- Side-emitting LEDs are aligned with the optical assembly of the display device to illuminate the user's eye.
- Glints generated by the LEDs are detected by an eye tracking camera to determine the position and gaze of the eye.
- A mirror is positioned between the LEDs and the display to reflect light beams and prevent double glints.
- Computer-generated content is projected onto the eye using a waveguide display based on the eye's position and gaze.
Key Features and Innovation:
- Use of side-emitting LEDs for eye illumination and glint generation.
- Mirror to prevent double glints and ghost signals.
- Eye tracking system for determining eye position and gaze.
- Integration with a waveguide display for projecting computer-generated content.
Potential Applications:
- Virtual reality and augmented reality headsets.
- Medical devices for eye tracking and diagnostics.
- Gaming and interactive entertainment systems.
Problems Solved:
- Accurate eye tracking for interactive applications.
- Mitigation of double glints and ghost signals.
- Seamless integration with near-eye display technology.
Benefits:
- Enhanced user experience in virtual and augmented reality environments.
- Precise eye tracking for medical and research purposes.
- Improved performance in gaming and interactive systems.

Original Abstract Submitted
an eye tracking system with in-optical-assembly plane illumination is described. side-emitting light emitting diodes (leds) aligned with a plane of an optical assembly of a near-eye display device are used to illuminate the eye of a user and generate glints that can be detected by an eye tracking camera. a waveguide display of the near-eye display device projects computer-generated content to the eye. a mirror is positioned between the leds and the waveguide display to reflect light beams generated from the leds toward the waveguide display to mitigate any double glints that may cause ghost signals. a processor of the near-eye display device determines a position and gaze of the eye based on the captured image of the eye with the glints, and generates the computer-generated content for the waveguide display based on the position and gaze of the eye.
