Shared AR

Shared AR allows multiple users to experience the magic of AR together. With Shared AR developers now have the power to connect multiple users in real-time or even asynchronously. Leveraging the Unity platform, you can now use Shared AR in your Unity projects to create multi-user experiences that allow people to connect and socialize within an app.

Why use Shared AR?​

With Shared AR, you will be able to use these features:

  • Connect multiple users (up to 10) together in a room.
  • Bring players into the same room with VPS.
  • Send networked messages to peers through Shared AR's relay server.
  • Use Unity's Netcode for GameObjects with Shared AR.

Shared AR is re-imagined for ARDK 3.0 which unlocks new, social and collaborative use-cases.

To setup Shared AR, see How to Use Shared AR. To setup shared objects, see How to Display Shared Objects. To run a Shared AR sample, see Shared AR VPS. For tips on debugging Shared AR, see How to Debug Shared AR.

Shared AR uses the Shared Space Manager to manage colocalization. There are three types of colocalization:

  • VPS Colocalization uses a VPS-Activated location as the center of a shared experience. This is the default you can see in How to Use Shared AR.
  • Image Tracking Colocalization uses an image in the real world as the center of a shared experience. For more information, see How to Use Image Tracking Colocalization.
  • Mock Colocalization does not center the shared experience, it only tests networking. It is useful for debugging between the Unity editor and a device. For more information, see How to Debug Shared AR.

To send networked messages using Shared AR, see the SharedAR.Netcode and SharedAR.Networking namespaces.

Regional Support​

Shared AR now supports regions outside North America.

Clients will automatically re-route to the best region based on their locale. Shared AR will have better round trip times (RTT) for clients in AMEA, APAC, and North America. On average, clients in AMEA and APAC should see a 100ms reduction in round trip times. Users in North America (US Central) will see the same performance as before.
