AR Camera GYRO — Unity Asset that uses camera and gyroscope on the player’s mobile device to display 2D or 3D objects as though they were in real world.
Cross-platform mobile gyroscopic camera implements markerless augmented reality (AR) by using a gyroscope sensor (like Pokemon GO).

AR Camera GYRO and ARKit, ARCore
There is no integration with ARKit & ARCore.
Unity AR Camera GYRO operates with gyroscope without surface detection to cover a wider range of mobile devices than ARKit & ARCore.

- 2 modes with Auto Rotation: Portrait, Landscape.
- 3-minute installation for your own AR Scene.
- Same AR as in Pokemon GO game.
- Covering a wide range of mobile devices.

Package is a part of Unity Assets
- VR + AR: Mixed Reality (MR) (docs).
- AR Toss Boss (docs).
- AR Basketball GO (docs).
- AR Survival Shooter (docs).

All modules are designed independently to keep this asset extendable & easy to understand:
Gyro vs. Accelerometer
90% of all mobile devices have an accelerometer and video camera but only 20% have a gyroscope.
You can also try to use both cameras for different cases.
Different devices have different gyroscopes, and therefore different deviations and drifts.
Drift is natural for mobile gyroscope sensor.
Tested with Devices
- iOS on iPhone 6, 8.
- Android on Samsung Galaxy S7 & S10.
- UWP on Microsoft Surface Pro 5, Acer Switch 5.

AR Camera GYRO prefab & GyroCameraControl.cs
ARCameraGYRO prefab has main camera control script: GyroCameraControl.cs.
Gyroscope Camera for virtual world rotating depending on the gyro data.
Option: On Gyro Is Not Supported
You can assign a function (in the inspector) to be executed if the gyroscope is not supported by your smartphone. By default, you will see screen message: “Your device does not support gyroscope”.
Option: Is Gyro Disabled On Destroy
If it’s ‘true’ then Gyro’s “Y” Rotation is resetted on Scene Closing or Reloading.
Interface into the Unity Gyroscope. Use this variable to access gyroscope.
Is a gyroscope available on the device?
rotationFix = new Quaternion (0f, 0f, 1f, 0f);
Unity AR bugs: Gyroscope
- Fixed in Unity 2018.2: INPUT.GYRO is extremely laggy on Samsung Galaxy S6, S6 Edge and S8 with Android 7.0.
- Fixed in Unity 2017.2: INPUT.GYRO.ATTITUDE returns acceleration’s values.
- Hardware Issue: INPUT.GYRO.ATTITUDE returns zero values on Motorola Moto G4 and G5.
Vote on these issues and comment them.
It’s important for Unity Team, so users should pay them attention to the situation.
Black screen on iOS
You just need to fill Camera Usage Description in Unity Editor.
Go to Unity Editor > Player Settings > iOS > Other Settings > Camera Usage Description > Fill it (any note for your app).
