This automates the process of flying through a door. The user can fly up to a doorway, press a button, the drone will auto align with the door, and fly through it. This takes the responsibility of flying through narrow doorways from the user so they can focus on the camera feed.
This allows the user to change which camera they are viewing on the UI (front or left). If the user changes the camera from say the front to the left, the front of the drone from a controls perspective changes as well. In that case, now the left side of the drone becomes the front if the user pushes the stick forward. This is great for heads-down flight where the user is flying from the perspective of the pilot tablet and not while looking at the drone. It allows for a user to glance into a room as they fly by or quickly navigate an area while heads-down but ensuring they can see where they are going.
This is a togglable feature on the pilot tablet that keeps the drone in the center of a hallway as they fly though a building. Like obstacle avoidance, this is good for a user that does not want to even think about flying and just wants to push forward and get to where they are going. Again, people that are used to flying drones will probably not like this feature.
