public class XRInteractionSimulator : MonoBehaviour
Remarks

This class does not directly manipulate the camera or controllers which are part of the XR Origin, but rather drives them indirectly through simulated input devices.

Use the Package Manager window to install the XR Interaction Simulator sample into your project to get sample mouse and keyboard bindings for Input System actions that this component expects. The sample also includes a prefab of a GameObject with this component attached that has references to those sample actions already set. To make use of this simulator, add the prefab to your scene (the prefab makes use of InputActionManager to ensure the Input System actions are enabled).

Note that the XR Origin must read the position and rotation of the HMD and controllers by using Input System actions (such as by using ActionBasedController and TrackedPoseDriver) for this simulator to work as expected. Attempting to use XR input subsystem device methods (such as by using XRController and UnityEngine.SpatialTracking.TrackedPoseDriver) will not work as expected since this simulator depends on the Input System to drive the simulated devices.
