public class MetaAimHand : TrackedDeviceRemarks
For this type to function, you must enable hand-tracking and be running with either the OpenXR or Oculus plug-in.
The devicePosition and deviceRotation inherited from TrackedDevice represent the aim pose. You can use these values to discover the target for pinch gestures, when appropriate.
Use the XROrigin in the scene to position and orient
the device properly. If you are using this data to set the Transform of a GameObject in
the scene hierarchy, you can set the local position and rotation of the Transform and make
it a child of the CameraOffset object below the XROrigin. Otherwise, you can use the
Transform of the CameraOffset to transform the data into world space.

Methods
| Name | Description |
|---|---|
| CreateHand(InputDeviceCharacteristics) | Creates a MetaAimHand and adds it to the Input System. |
| FinishSetup() | Perform final initialization tasks after the control hierarchy has been put into place. |
| UpdateHand(bool, MetaAimFlags, Pose, float, float, float, float) | Queues update events in the Input System based on the supplied hand. It is not recommended that you call this directly. This will be called for you when appropriate. |
| UpdateHand(MetaAimFlags, Pose, float, float, float, float) | Queues update events in the Input System based on the supplied hand. It is not recommended that you call this directly. This will be called for you when appropriate. |
