anyone got thoughts on this?
I rage-wrote a meta post
before the heading is "It's been pointed out that this hasn't really been brought up in meta. (It's only been discussed in chat) So, for the sake of non-chatters:" in regular font, but it didn't fit in the screenshot

That looks good to me, I don't mind you bringing me up - possibly there are other users who use screen readers we can ask for a second opinion? It's possible some people have screen readers that can process MathJax and I'm curious if we could search for other user experiences with it.

1:31 AM
looks pretty good :)

just rejected an edit that ADDED mathjax to a post that didn't need it

Affix riddles are really versatile; they come in all forms. I have an issue with the tag wiki of the affix-riddle tag.

Yeah :p
For the meta post, I found a blurb on MathJax's website listing the screen readers that fully support the internal MathJax language and can read it. There are only three of them. (ChromeVox, JAWS on Internet Explorer only, and Texthelp.) Other screen readers have to use the AssistiveMML extension, which says "the quality of MathML support in screenreaders varies greatly."

Not to mention that mathematics notation itself is ambiguous as hell, and one often needs to understand the context in order to read it out correctly

Yeah. So overall it's a mess

"hot" takes from the person who takes their lukewarm 2 well that's better than burning hot heathen. you will burn in a steaming cup of hot cocoa docs.google.com/document/d/… <-- anyone want to look over latest draft of MathJax PSA? gtg, sorry, bobble 4:48 AM see you! See you msh :) Just stopped in to contribute to the hot cocoa debate. I will probably head off to bed soon, it's almost midnight here. The addition about variability between different screen readers is good, i actually quickly tested ChromeVox and even that one - which is supposed to natively support MathJax - didn't quite do it right There's a big mixed bag of "supports it kinda," "supports it but only with an extension," and "doesn't support it at all" Possibly you can also mention that unnecessary MathJax font might cause problems for people with dyslexia - I can't personally verify that, but that was a very common topic as well on forums if you can get some links that would be good I will find some sources for that, hang on The main point of your post stands either way, though - using it where it's not necessary is just generally excessive and causes accessibility issues. ncbi.nlm.nih.gov/pmc/articles/PMC5977080 This paper is a bit of an academic slogfest, but has source-able information about how changes from serif to sans serif fonts and fonts with ornaments (like MathJax fonts) can cause dyslexic readers to struggle. It's not the math itself, it's changing randomly from MathJax to regular font and back 5:12 AM i'd say for more complicated expressions, mathjax makes sense: things like fractions with square roots or exponents in them, or complicated exponents. anything that needs to be displayed 2-dimensionally for more clarity. (yes, technically you can flatten the quadratic formula into "x=(-b±√(b²-4ac))/(2a)", but it makes the structure much harder to parse) but there is absolutely no point using it for numbers and operations like +-× alone, without any variables or exponents -- that's the biggest issue i've seen Using it for complex expressions where it helps in readability is totally fine, nothing wrong with that at all - our issue is more when people edit in MathJax for individual numbers and put it in just for a fancy font. oh absolutely i agree 100% -- i just wanted to say that i might change the wording slightly in the PSA to focus on cases like that That's completely fair - wording could emphasize that more also agree @Deusovi if you have a google account I could add it as an editor 5:21 AM just requested edit access where do I look to approve your access? ...no idea. email? ah, there it is you should have access now feel free to edit away 5:38 AM @bobble made a few edits, and left some other comments 5 hours later… 10:22 AM @Sciborg I don't add sugar, but that's because Israeli hot chocolate powder has a ridiculous amount of sugar added already. I will sometimes add coffee, though. And / or vanilla soy milk. 1 hour later… 11:25 AM If accessibility weren't an issue then I would advocate for using MathJax a lot in places where it's needed at all. E.g., if you have a formula with numbers and variables in it that needs MathJax-ing, then in purely aesthetic terms you should also MathJax individual instances of the variables and relevant numbers in the rest of your text. Obviously (1) none of that applies if you don't have mathematics that requires MathJax in the first place -- if all you're doing is saying "if 4x+3y=7 and 2x+3y=5 then what are x and y?" you can write that OK without MathJax and probably should. (Though the equations will look better with MathJax, and then the argument above would say that aesthetically you should MathJax the isolated x and y too.) And (2) accessibility is generally more important than aesthetics for obvious reasons. But here's a question. Suppose you are writing something that does contain some mathematics complicated enough that you need MathJax for it. Someone who's using a screen reader that can't cope with MathJax is then going to be missing something essential. So maaaybe -- it depends on what they can and do do about that situation -- maybe once you've got any nontrivial MathJax there's not much accessibility argument against adding more. If the situation is that someone with a non-MathJax-savvy screen reader who encounters a lump of MathJax can then launch some other bit of software that can interpret it for them, but that doing so for three bits of MathJax is 3x as much work as doing it for one, then accessibility means not only avoiding MathJax when you can but also minimizing how often you use it. Likewise if the situation is that their screen reader will say what the MathJax says but in some form that's unpleasant or difficult to make sense of: you're paying a price every time it happens. On the other hand, if the screen reader just gives up entirely and there's no realistic alternative, then something to which something that needs MathJax is essential is just inaccessible and won't be made any more or less so by MathJaxing individual variables and the like. Or if what happens is that the screen-reader user calls someone else over and says "hey, could you read this out for me?". Once they're doing it at all, there's probably little extra cost to having them do it for the whole thing. (Depends on the details of the thing, of course.) (There are other costs to using MathJax that don't have much to do with accessibility, or at least with accessibility-for-people-with-impairments. For instance, if your network connection is slow then MathJax will cause a bit of pain.) Anyway, @bobble your PSA is pretty good. I have a few suggestions. 1. Show both the input and the output for at least some of the cases where you're comparing MathJax with non-MathJax, so people can see how to do it. 2. In many cases the non-MathJax way is "just use the special characters that are part of the Unicode repertoire" and it might be worth giving, or linking to, some advice on how to enter those characters. 3. Have you verified that all those things come out OK [... continues] ... in common screen readers? I'd be a little concerned about whether subscripts and superscripts come out right, and slightly concerned about whether some less-common characters might turn into something like "Unicode character 20F3". (I have not checked what Unicode character 20F3 actually is.) 4. As you can see above, I'm not very sure how strong a case there is for minimizing MathJax in a post that has to use it anyway, as opposed to avoiding MathJax completely if you can, but it may be worth saying a few words about that issue. 5. It feels a bit odd to go from "... a wonky extension which doesn't work with more complicated math" straight to "so don't use$1$where 1 will do", since that's pretty much the least complicated thing you can do in MathJax. It feels to me like almost all the advice in the PSA doesn't help in the case where someone has a screen reader with a wonky extension that's OK with simple things but falls over with more complicated ones -- because the more complicated cases are [... continues] ... exactly the cases where there isn't really any alternative to MathJax in the first place. So the advice "when you can write something adequately without MathJax, do so" isn't going to make anyone turn complicated formulae into plain text, because plain text isn't an adequate representation for complicated formulae, which is why we have mathematical notation in the first place. I guess pretty much any formula can be turned into prose if you really have to, but the result is going to be super-unpleasant to read for everyone. 12:38 PM 0 Sweden Ashton Kutcher salmon dogs Emma stone Germany elk Chicago Miami Margot Robbie heart transplant countryside 1:02 PM 0 You start with an empty 5x5 grid.

Stack Exchange Incorporated ugh, doubting my PSA now that I've slept on it what don't you like about it? 3:20 PM everything you pointed out, and then Rand in the Lit chatroom saying MathJax should be used for all math I suspect Rand just wasn't thinking about the accessibility issues. the real solution would be to make MathJax compatible with screen readers That would be a great solution. Not so easy for us here to do, though. Is it open-source? :P do you want edit access too Gareth? you could make any changes you like 3:41 PM @GarethMcCaughan after talking with bobble about it (in the document last night, while i was helping edit it), i was planning to make a followup answer with some copy-paste-able characters as for the things you brought up about complexity, i agree that "$1\$ vs 1" is the least complicated case, but it's the main 'target' of the post, so to speak -- i've noticed a fair bit of that kind of thing in the past
(and i'd recommend using the mathematical variable characters if you just need stylized single letters to distinguish, say, "a" from "𝑎" : 𝑎𝑏𝑐𝑑𝑒𝑓𝑔ℎ𝑖𝑗𝑘𝑙𝑚𝑛𝑜𝑝𝑞𝑟𝑠𝑡𝑢𝑣𝑤𝑥𝑦𝑧. as far as i know, screen readers do work fine with these)

I thought screenreaders hated those too?

they hate those when used as italics for full words
because 𝑐𝑎𝑡𝑠 would get read out as "MATHEMATICAL ITALIC LOWERCASE C MATHEMATICAL ITALIC LOWERCASE A MATHEMATICAL ITALIC LOWERCASE T MATHEMATICAL ITALIC LOWERCASE S", or something along those lines

Ooh, interesting

so you absolutely should not use those characters for fancy formatting
but if you're using the characters for their actual purpose -- as variable names, distinct from plain text -- then that's exactly what you want.

@Deusovi Hey! My teacher is going over the same stuff we did for angle addition Tueday and today!
Except her diagram is waaaay more complicated

oh neat

Yeah, that's really messy and confusing

ahh yeah - that's actually relatively similar, they just draw more lines around the border to make that final addition/subtraction step more clear

Yeah
It is similar, but the extra lines are a bit more confusing

makes sense - i think the extra lines help some people?

4:13 PM
Maybe
AHAHAHAHAHA we're also going over the e^i formula!
Dang Deus, prepping me ahead of time :)
Or wait
Not yet

4:33 PM
And now we get to the e^-ix :)

that's like e^ix, except in the other direction

Woah, no way

4:46 PM
@Deusovi Yup, I appreciate that the main target is the use of MathJax for trivial things rather than substantial formulae. It's for that reason that I wonder whether the case of screen-readers that can read easy formulae but can't read hard ones is relevant.

that's a good point - it might be cleaner if that was edited out

poofy/screeny?

Poofy is still sitting under my tree, I am working on finding her a little Santa hat

or you could get her a big santa hat and have it cover her

but then she couldn't see anything

It's okay, bobblies navigate by echolocation and/or smelling puzzling juices

i imagine that would be quite annoying for her
@Sciborg what does puzzling juice taste like though?

Hang on, let me ask Poofy
that's weird, she says it tastes like ichor and the blood of her enemies?

you don't want to make the bobblies your enemy

it's okay, she'll cheer up once i find her the Santa hat.

let's hope so
