The Head property provides the position and rotation of the Head Mounted Display (HMD) in local space coordinates. This property is essential for determining the user's viewpoint in a virtual reality environment, allowing for accurate rendering of the scene from the user's perspective.

To access the Head property, you need to reference the VRInput class. This property is not static, so you must access it through an instance of VRInput. Typically, you would use the Current property of VRInput to get the active instance.

Example usage:

Transform headTransform = VRInput.Current.Head;
Vector3 headPosition = headTransform.Position;
Quaternion headRotation = headTransform.Rotation;

In this example, headTransform is used to retrieve the position and rotation of the HMD, which can then be used to adjust the camera or other elements in the scene to match the user's view.
