## Properties

- hand : enumeration

## Detailed Description

Contains an animated 3D model that tracks the user's hands.

XrHandModel is only visible when hand tracking is active.

Note: XrHandModel depends on hand-tracking data from the underlying system and is, therefore, not available on all platforms.

## Platform Notes

### Apple Vision Pro

The Apple Vision Pro will overlay video of the user's hands directly, and the XrHandModel will not have any content.

### Meta devices

This required the following feature and permission lines to be added in the AndroidManifest.qml file of your project.

     <uses-permission android:name="com.oculus.permission.HAND_TRACKING" />
     <uses-feature android:name="oculus.software.handtracking" android:required="false" />

Use `true` instead of `false` in the `uses-feature` tag if your app's interaction is implemented only for hands.
