So, I was reading about this Dragon V2 and it has got touch controlled screens, but screen might be unreadable for pilots because of engine vibrations and whatnot. I came across this comment on reddit.
"I read an article on the SLS/Orion. They had a problem with vibrations making screens unreadable. It would have cost millions of dollars to dampen the pod vibrations so the pilots could read their instruments. Then a scientist realized that if you changed the monitor refresh rate to match the vibrations, the screens looked perfectly clear. The million dollar fix was abandoned for a 10 cent accelerometer that adjusted the refresh rate automatically. I see no reason why spacex couldn't use this solution to make the screens useful in the rigor of flight. "
Yeah, so, why does matching refresh rate with vibrations solves this?
