EYE TRACKING SYSTEM WITH IN- PLANE ILLUMINATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18342277 titled 'EYE TRACKING SYSTEM WITH IN- PLANE ILLUMINATION
Simplified Explanation
The abstract describes an eye tracking system with in-optical-assembly plane illumination using side-emitting LEDs aligned with a plane of an optical assembly of a near-eye display device.
- LEDs aligned with the optical assembly plane illuminate the user's eye to generate glints for eye tracking.
- Corrective optical elements in the assembly that distort LED beams are mitigated by using angled beams from in-package or modified LEDs.
- Mitigations such as reflectors or labels in the LED package help reduce distortion.
- Edge portions of distorting optical elements may be shaped or complemented with refractive elements to redirect beams towards the eye.
Potential Applications
This technology can be applied in:
- Virtual reality headsets
- Augmented reality glasses
- Eye tracking research studies
Problems Solved
- Distortion of illumination beams in eye tracking systems
- Ensuring accurate eye tracking data
- Improving user experience in near-eye display devices
Benefits
- Enhanced accuracy in eye tracking
- Reduced distortion in illumination beams
- Improved performance of near-eye display devices
Potential Commercial Applications
- Gaming industry for immersive experiences
- Healthcare for medical simulations
- Market research for consumer behavior analysis
Possible Prior Art
One possible prior art is the use of external light sources to illuminate the eye for eye tracking in virtual reality systems.
Unanswered Questions
1. How does the system handle variations in eye shapes and sizes for accurate tracking? 2. What are the potential limitations of using LEDs for eye illumination in different lighting conditions?
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. When a corrective optical lens or similar element is included in the optical assembly that may distort illumination beams from the light emitting diodes (LEDs), the distortion is mitigated by using in-package or externally modified LEDs that provide angled beams. In addition to in-package level mitigations such as reflectors or labels, edge portions of the distorting optical elements may be shaped or complemented with refractive elements to redirect the beams toward the eye.
