# TrackingOriginModeFlags

> This enum provides context to where the 0,0,0 point of tracking for InputDevice s is.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.XR](/engine/6000.0/script-reference/unityengine/xr.md)
* **Assembly:** UnityEngine.XRModule

```csharp
public enum TrackingOriginModeFlags
```

## Remarks

Each [XRInputSubsystem](/engine/6000.0/script-reference/unityengine/xr/xrinputsubsystem.md) has a single origin for all reported [InputDevice](/engine/6000.0/script-reference/unityengine/xr/inputdevice.md)s. The origin can be relative to either real-world objects, such as a physical tracking device, or virtual objects, such as the center of a user-drawn bounding region.
