Spatial annotation is the placement of digital notes, labels, or markers anchored to specific positions in a three-dimensional physical or virtual space, so that the content persists relative to real-world geometry as the viewer moves. It relies on spatial mapping and pose tracking to keep annotations registered to surfaces or objects. It is a foundational interaction for augmented reality collaboration, maintenance guidance, and shared spatial computing.

Content

  • It depends on spatial mapping and continuous pose tracking to keep each annotation fixed to its target surface or object across sessions and viewpoints. The capability enables an AR Overlay to support persistent collaborative markup, remote-assist guidance, and shared spatial computing where multiple users see the same anchored content in situ.
