QR as Spatial Anchors: The Bridge to Augmented Reality
In the era of Apple Vision Pro and Meta Quest, QR codes are finding a second life as AR "Anchors."
Global Positioning vs. Visual Positioning
While GPS is accurate to 10 meters, it fails indoors. A QR code placed on a wall provides a "Zero Point" for an AR headset, allowing it to overlay 3D information (like a navigation line on a floor) with millimeter precision.
WebAR Integration
By scanning a QR, a user can launch an AR experience directly in the browser (via 8th Wall or A-Frame) without installing an app. This "Instant Try-On" or "3D Furniture Placement" is revolutionizing e-commerce.
The Stealth Marker
Future iterations of QR codes may use infrared or ultraviolet inks, making them invisible to the human eye but easily readable by AR sensors, preserving the aesthetic purity of physical spaces.
