* 네비게이션 경로는 NavigationController.FindPath() 함수의 파라미터인 **place\_unique\_name**를 통해서 요청하게 됩니다. place\_unique\_name는 placeId를 통해서 획득하게 됩니다.
* 요청된 결과로 현재 사용자의 위치로 부터 목적지까지의 경로를 얻게 됩니다.
* MakeNavigationArrowContent() 함수로 컨텐츠 결과물을 확인할 수 있습니다.
* 네비게이션 검색 파라미터는 Trackable에 포함 되어 있습니다.
* 목적지에 대한 좌표는 POI를 통해서 획득 하거나, 메쉬의 주변부의 좌표를 획득해서 얻을 수 있습니다.
