Install Headset Calibration (Unity SDK)

Add AR 51 Headset Calibration to a Unity project with Package Manager (recommended) or a .unitypackage — or try it first with the ready-made demo app.

Requirements​

  • Unity 2022.3 or newer, with Android Build Support for Quest standalone.
  • Git and Git LFS installed on the computer.
  • Quest Link needs nothing extra on Windows.

In Unity, open Window ▸ Package Manager ▸ + ▸ Add package from git URL…

The + menu in Unity Package Manager with Add package from git URL selected

Add these three URLs, in this order:

1 — AR 51 Unity SDK
https://bitbucket.org/ar51/ar51-unity-sdk.git?path=/AR51.Unity.SDK#v3.0.3.2
2 — AR 51 Unity SDK - Meta XR (Quest)
https://bitbucket.org/ar51/ar51-unity-sdk-integrations.git?path=Packages/com.ar-51.unity-sdk.oculus#v3.0.3.2
3 — AR 51 Unity SDK - Headset Calibration
https://bitbucket.org/ar51/ar51-unity-headset-calibration.git?path=/AR51.Unity.SDK.HeadsetCalibration#v3.0.3.2
Why three, and why in order

Unity doesn't install packages from git links on its own, so the AR 51 SDK and its Meta Quest package must be added first. The Meta XR SDK and Unity UI are installed automatically.

When it's done, Package Manager lists AR51 Unity SDK, AR51 Unity SDK - Meta XR (Quest) and AR51 Unity SDK - Headset Calibration, all at version 3.0.302. Select the calibration package to see the git URL it was installed from and its Samples tab, which has the Calibration Demo scene.

Unity Package Manager listing AR51 Unity SDK, AR51 Unity SDK - Headset Calibration and AR51 Unity SDK - Meta XR (Quest), all 3.0.302 from Git, with the Headset Calibration package selected

.unitypackage (alternative)​

  1. Download AR51.Unity.SDK.HeadsetCalibration (3.0.3.2R).unitypackage from the download page.
  2. Open a project that already has the AR 51 Unity SDK 3.0.3.2 and the Meta XR Core SDK.
  3. Import it with Assets ▸ Import Package ▸ Custom Package…

Try it without Unity​

The download page has a ready-to-run demo app:

  • Windows (Quest Link): unzip AR51.HeadsetCalibration.Demo.Windows (3.0.3.2R).zip, connect the headset with Quest Link, and run AR51HeadsetCalibrationDemo.exe.
  • Quest standalone: install AR51.HeadsetCalibration.Demo.Quest (3.0.3.2R).apk on the headset. Installing an APK needs the headset in developer mode — for example with Meta Quest Developer Hub or adb install.

Both demos find the AR 51 system automatically on your network. Put the headset on and follow the tips for the wearer.

Build it yourself — a working scene from an empty project.
