I've watched all the YouTube videos and tiktoks about the spice and the guild navigators.. basically they're what exists instead of decision making computers.

But what do they actually do to operate the ship? Like they looked and saw some shit and now they have to do something about it.

Does the navigator have buttons and levers to configure the drive? Do they just speak words to some sort of helmsman about how to steer? Do they write out instructions? Is there some sort of telepathy or telekinesis the navigator does with the hardware?

Whenever I Google it I just find articles and videos about spice. What about SOP?
