Gaze vs. View A Framework for Correlating Dynamic and Static Measurements in AR Optics

Precise characterization of augmented reality (AR) glasses is essential for evaluating optical performance, guiding engineering decisions, and ensuring user comfort. However, current measurement approaches are often limited by inconsistent terminology and missing standardized spatial reference frames, making it difficult to compare results across devices, setups, and laboratories. As a result, performance assessment frequently remains subjective.

This talk proposes a metrological framework that is explicitly anchored to the Human Visual System (HVS). By defining a quantified standard observer eye model as the ultimate reference, a rigorous and application-relevant basis for AR glasses characterization can be established. In an ideally aligned measurement setup, the optical elements of the eye model, the device under test (DUT), and the light measurement device (LMD) form a co-axial metrological chain. In this configuration, homologous points coincide spatially, enabling consistent, reproducible, and comparable measurements. The approach provides a foundation for objective performance evaluation and cross-platform comparability in AR display metrology.
