Navigation in smart glasses has transitioned from simple audio pings to visual AR overlays that "pin" digital arrows to real-world streets. In 2026, the technology is split between Visual HUDs (Heads-Up Displays) and Audio-Only systems.

SLAM (World-Locking): High-end models like the RayNeo X3 Pro use SLAM to anchor arrows to the ground. If you turn your head, the arrow stays "pinned" to the intersection instead of moving with your eyes. Smartphone Mirroring vs. Native GPS: Most glasses, including the RayNeo Air 4 Pro, mirror your phone's Google or Apple Maps. This is safer as it keeps you in a familiar app environment while the glasses handle the heads-up display.
