EYE MOVEMENT DETERMINATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240310906 titled 'EYE MOVEMENT DETERMINATION
Simplified Explanation:
The patent application describes a method for operating a display of a virtual reality or augmented reality headset by determining the direction of movement of a user's eye, estimating a future gaze direction, and rendering images with varying resolutions based on the estimated gaze direction.
- The method involves using a laser to illuminate the user's eye, measuring self-mixing interference to determine the direction of eye movement.
- Higher resolution image data is rendered in the region of the estimated gaze direction, while lower resolution data is used outside of this region.
Key Features and Innovation:
- Use of laser technology to determine eye movement direction.
- Adaptive rendering of images based on estimated gaze direction.
- Combination of high and low-resolution image data for optimized display.
Potential Applications:
- Virtual reality gaming.
- Augmented reality training simulations.
- Medical imaging and diagnostics.
Problems Solved:
- Enhancing user experience in virtual and augmented reality environments.
- Improving accuracy of gaze tracking in headsets.
Benefits:
- Sharper image quality in the user's line of sight.
- Reduced processing power required for rendering.
Commercial Applications:
Optimizing display technology for virtual and augmented reality headsets to enhance user experience and expand applications in gaming, training, and medical fields.
Questions about Eye Tracking Technology:
1. How does the use of laser technology improve eye tracking accuracy in virtual reality headsets?
Laser technology allows for precise measurement of self-mixing interference to determine the direction of eye movement, leading to more accurate gaze tracking.
2. What are the potential limitations or challenges of implementing this eye tracking method in commercial VR/AR headsets?
Potential challenges may include the cost of integrating laser technology, ensuring compatibility with existing hardware, and addressing any safety concerns related to laser use in consumer devices.
Original Abstract Submitted
a method for operating a display of a virtual reality or augmented reality headset includes determining a direction of movement of a user's eye, estimating a future gaze direction from the determined direction of movement, and rendering an image on the display having higher resolution image data in a region including the estimated gaze direction and lower resolution image data outside of the region including the determined gaze direction. the determining the direction of movement of the user's eye includes illuminating the user's eye with a beam of light emitted by a first laser, receiving, at the first laser, light redirected from the user's eye_such that self-mixing interference occurs within the laser cavity between light generated by the first laser and the light redirected from the user's eye, measuring the self-mixing interference, and determining a direction of movement of the user's eye-from the measured self-mixing interference.
