Towards an Expanded Eyebox for a Wide-Field-of-View Augmented Reality Near-eye Pinlight Display with 3D Pupil Localization

A head-worn optical-see-through near-eye display (NED) is crucial for augmented reality (AR), enabling simultaneous perception of virtual and real imagery. Current AR NEDs face trade-offs among field of view (FOV), eyebox size, and form factor. We designed an enhanced pinlight AR NED using a novel approach to capture the pupil’s 3D location and compute a modulation pattern on the display. In our design, an eye-tracking camera rig captures stereoscopic views to calculate a display pattern, modulating light beams for precise imagery. Our compact prototype achieves a wide FOV of 79° in horizontal, a large eyebox, and experimental results confirm its spatial and temporal consistency.
