Gaze‐Engineered 3D Augmented Reality

Augmented reality (AR) is one of the core components of the metaverse. However, the vergence‐accommodation conflict (VAC) has hindered its development and application. This study proposes a novel gaze‐engineered 3D augmented reality (GE‐3D AR) system that integrates AR with human factors engineering to provide physical depth cues and address the VAC issue in AR systems. The GE‐3D AR system enables real‐time monitoring of the user's gaze point and adaptively renders images with depth of field corresponding to the visual characteristics of the human eye. Then these rendered images are rapidly projected onto the depth plane aligned with the user's gaze. A waveguide‐based prototype system has been constructed to validate the proposed approach, demonstrating the ability to achieve high‐quality display with a continuous depth range. Moreover, the system operates without the need for high‐refresh‐rate devices or high‐frequency oscillating components, achieving high stability and compactness. This work creates a new way for solving VAC in waveguide‐based AR systems.
