Eye-tracking offers vast potential for enhancing the XR experience. Despite the maturity of the technology, challenges persist in achieving the desired level of accuracy, robustness, and population coverage. The challenges arise from the variability of external features of the eye and corneal reflections as well as the many intermediates between them and the fovea. Retinal eye-tracking is a fundamentally different approach, not bound by these constraints. We developed a compact, power-efficient retinal eye-tracking system designed for XR HMDs, circumventing classic limitations and unlocking new possibilities for immersive experiences.
