The fact of the matter is, gaming peripherals are probably close to the very best we have in human/machine interfaces. They've been studied to oblivion and back, for over 40 years.
The Navy also has redundancies and procedures in place for when those controllers fail. The controller doesn't determine whether the crew lives or dies.

IIRC the controller is used for the periscope.
They've also been studied to Morrowind and Skyrim and back.
