AR users expect to put on AR Glasses and instantly get an augmented experience. To enable this ease-of-use, AR glasses designers create a large eyebox, using exit pupil expansion or replication. These brute force approaches are inherently inefficient in power consumption and challenged in achieving high image quality. EyeWay's much more efficient approach is to move a small exit pupil aligned with the visual axis of an eye. This requires a low latency accurate eye tracker, low persistency light engine, and also an efficient exit pupil actuator. This approach allows power efficient AR Glasses with large eyebox, high brightness, high contrast, wide color gamut, dynamic focus, large perceived field of view, and retinal resolution image.
