US Navy will replace touchscreen with mechanical controls on its destroyers

I think knowing the temperatures and such amounts to predicting the foggy state. Detecting it could look much different. Visual observation is obvious. With purpose built glass, perhaps one could look at electrical properties on the inside of the windshield. Maybe changes in the reflectivity of the glass could be used. Maybe some refractive index shenanigans?

This seems like a simpler route. Why not just a camera pointed at a test mark on the windshield that checks if it is visible through the glass?

Or simply look for reflectivity at an angle, like the recent HN story about the guy who implemented a touchscreen on his Macbook by adding a small mirror to the camera above the screen.
