We study human factors for WEBXR overlays in RFoperations. Using a reproducible harness, we compare VR against2D baselines, sweeping overlay density and hint cadence underrealistic latency bands. We find that with p99 latency under 50 ms,VR improves time-to-localize by 27.9% on average, sustaining74.2 FPS at 30 overlays. A simple latency budget shows feasibilitybelow 50 ms … Continue reading WebXR for RF: Human Factors & Latency Bounds in VR Overlays
