AI Technical Summary
Existing eye tracking systems face challenges in achieving accurate, low-power consumption, low-latency, and safe operation, particularly in dark environments with minimal ambient light, while maintaining high signal-to-noise ratio and detecting small eye orientation changes.
An optical sensing system utilizing a projection means to project light onto the cornea, detecting reflections with single-photon avalanche detectors, and calculating eye movements based on Purkinje reflections, employing a movable or arrayed projection system and optical sensors with dynamic deflection mirrors to maintain focus and reduce power consumption.
The system achieves high accuracy and low latency in eye tracking with reduced power consumption, enabling applications in augmented, virtual, and mixed reality systems without requiring pupil tracking and allowing for user-specific adjustments.
