@modulux There is a similar, but sort of opposite, problem with support for deaf people. There, many people assume that written text is enough and think it’s okay to ignore the signed modality. But written text is always in another language than the deaf person’s first language.
If only people could ask someone who knows something about the subject instead of just guessing.
@modulux Heck, braille might be a useful thing for a lot of fully-sighted people to know. I'm thinking of all the times I've reached around the back of a piece of hi-fi or computing equipment, trying to find the right socket while using my memory of the layout (but reversed) as a guide, or maybe looking through a small mirror. If the sockets were all labeled in braille, on the other hand...
Caveat: It might or might not be practical (can braille characters still be legible when they're as small as most electronic socket-labels?), but I have to wonder. ...and I can't think there aren't other cases where it would be even more obviously a plus.
TLDR: it's kind of silly (at best) to withhold a tool from someone for fear that it will make them less functional.
@woozle Depends on the socket size, but in some cases, sure. Labelling the types of USB on a board for example would be doable. Some headphones have an L or R character in braille on them (Sennheiser does this, for instance). I am sometimes a bit amused, no offence meant, at how helpless most sighted people are in the dark. If they can't see something they don't even bother exploring by touch and so on.
@modulux Now that you mention it -- I remember just a week or so ago when I was trying to put in a screw from a really awkward angle (on the other side of a board), it actually worked better to just close my eyes and focus on the feel of it rather than trying to judge the angle from what I could see (which didn't include the actual contact point between screw and driver).
@woozle @modulux reminds me of when I was trying to learn to throw a basketball at the net in school P.E. (which sucked), and the only time I actually hit it was when I had the eyes closed.
But then, basketball at school was also when someone else threw the ball full force at the back of my head in frustration over me being so bad at it, and the teacher doing literally nothing about it (but at least didn’t complain when I refused to continue to participate for the remainder of the year, I had to still be present but could keep to the bench).
