I haven't seen any accessibility features for x86 machines that comes close to Apple's switch control on iOS, but I also don't actively look for it. I'm curious if other device manufacturers will try to get into this market as folks live longer on average in countries with socialized medicine.
Makes me think about how this would change my life were I in Mark's position. Would be interesting to see games that are very accessible, controlling your own media seems like an easy win, and so long as you can see and talk communicating on demand is a huge life improvement.
Would be interesting to hear a system designed for blind folks.
