This document discusses mixed reality and the use of spatial anchors. It begins with an introduction to spatial anchors and cloud spatial anchors, which provide a common frame of reference to place digital content in physical locations across devices. The rest of the document demonstrates how to create spatial anchors using Azure Spatial Anchors and Unity, provides examples of how spatial anchors can be used for collaborative design reviews, wayfinding and IoT applications, and concludes with information on resources and a question period.

9. What is a Spatial Anchor?
A common frame of reference to place
digital content in the same physical location
where it stays stable at the same position
and orientation relative to the real-world
environment.

14. What is a Cloud Spatial Anchor?
A common frame of reference for enabling
multiple users to place digital content in the
same physical location where it is persisted
and can be seen on different devices at the
same position and orientation relative to
the real-world environment.
