Create massive multiplayer games in the real world

Bring the best of mobile gaming and mixed reality together. Spatial Anchors enables players to find nearby content, share and play mixed reality experiences in a real-world location, and persist games and puzzles for discovery on later days, weeks or months. Build experiences such as Minecraft Earth, holographic scavenger hunts, or digital escape room puzzles.

Enable collaborative experiences across platforms

Share mixed reality content on all the devices that work best for your solution, for scenarios like training and design review. Spatial Anchors supports HoloLens devices, ARKit-enabled iOS devices, and ARCore-enabled Android devices. Build your apps using Unity or your favorite native SDK for the devices you choose to support.

Frequently asked questions about Spatial Anchors

  • Mixed reality is the result of blending the physical world with the digital world. It adds interactive holograms to your real environment. Holograms are objects made of light and sound that appear in the world around you and obscure what's behind them as if they're real. Using artificial intelligence, holograms in mixed reality respond to commands and interact with real-world surfaces in real time.

  • Across augmented reality (AR) platforms, "anchors" are a common frame of reference for enabling multiple users to place digital content in the same physical location, where it can be seen on different devices in the same position and orientation relative to the environment. With Spatial Anchors, you can add anchor persistence and permissions, and then connect anchors in your application so that your users can find nearby content.

  • Spatial Anchors offers platform support for Unity, ARKit, ARCore, and UWP. Create your first app using quickstart templates for HoloLensUnityiOS, and Android.

  • Spatial Anchors supports all HoloLens devices. Today we offer documentation support for HoloLens Development Edition and HoloLens Commercial Suite, and documentation for HoloLens 2 is coming soon. You can also use this service in apps running on iOS-based devices supporting ARKit, and Android-based devices supporting ARCore.
