 * If the user views selections as described in MANUAL_ONLY mode, the interaction becomes strictly, and irreversibly, a MANUAL_ONLY interaction (i.e. the VR session is cancelled, although the interaction itself is still in progress). If the user interacts with the VR session in any way (e.g. speaks a phrase, even if it is not a recognized choice), the interaction becomes strictly, and irreversibly, a VR_ONLY interaction (i.e. the MANUAL_ONLY mode forms of interaction will no longer be honored)
 *
 * The TriggerSource parameter of the *PerformInteraction* response will indicate which interaction mode the user finally chose to attempt the selection (even if the interaction did not end with a selection being made)
