I’m color blind and really, really appreciate the accommodation for that for sure.
When I was in university I was a resident advisor in a mixed deaf/hearing dorm and ended up learning a little sign language and lip reading along the way but also was exposed to a lot of things. For instance the fire alarms in the building also had strobe lights and alarm clocks would make the bed shake and so forth.
I also play WoW with no sound and have become used to the visual ques in the game (there is almost always a visual que for everything). It occurs to me though, that like the color blindness system a haptic/tactile device support would be really interesting (even for hearing people!)
An example of some PC haptic systems:
