AR Spatial Web Standard SpatialWeb Approved by Khronos Group: Physical and Digital Worlds Get a Unified Addressing Protocol for the First Time

AR Spatial Web Standard SpatialWeb Approved by Khronos Group

On October 9, 2030, graphics standards organization Khronos Group officially released the SpatialWeb 1.0 standard. SpatialWeb defines a unified addressing and interaction protocol for digital objects in physical space, enabling different AR devices to locate, read, and modify the same set of digital content in the real world.

SpatialWeb's core concept is the "spatial anchor" — binding digital information to precise locations in the real world. For example, a restaurant can place a spatial anchor at its entrance linked to an AR menu; when a user walks by, their AR glasses automatically detect the anchor and display the menu content. Different brands of AR devices (such as Apple Vision Pro, Meta Quest, Xreal) can all read the same anchor.

The SpatialWeb protocol stack comprises three layers: the spatial layer (defining physical coordinate encoding), the semantic layer (defining digital object types and attributes), and the interaction layer (defining user interaction rules with digital objects).

Neil Trevett, chair of the Khronos Group SpatialWeb working group, said: "SpatialWeb is the TCP/IP of the AR internet. Just as TCP/IP enables different devices to communicate over the internet, SpatialWeb enables different AR devices to share digital content in the same physical space."

The first AR devices to support SpatialWeb include Apple Vision Pro 2 and Meta Quest 4, expected to be enabled in system updates in the first quarter of 2031. Multiple spatial computing startups have announced plans to build applications on the SpatialWeb standard.
