Q: Reference request for educational material In source format, for blind accessibility purposes

Hussain KadhemIntroduction I am a blind undergraduate studen in mathematics. I use screen reading software, which uses synthesized speech to read aloud the contents of the screen, to read and write math. Due to the limitations in presentation-focused formats like PDF and MathJax, screen readers can't properl...

A: Problem with MathJax and Screen Readers

Peter KrautzbergerDisclaimer: I'm part of the MathJax team. Also, this got a bit long. tl;dr Try out NVDA with MathPlayer 4 on Firefox here on math.SE JAWS 13 is a bit old (2011) and the situation of screenreaders with respect to math and the web has changed drastically since then. As already mentioned, JAWS 16 ...

> To improve the situation, we developed a new extension (AssitiveMML.js) as part of the MathJax v2.6 release. This is currently in beta testing here on math.SE. The extension embeds MathML alongside the visual rendering hiding the visual rendering from AT and the MathML from being visible. That's clearly not ideal - in fact, usually bad practice - but it's the pragmatic solution we followed after feedback from AT vendors and accessibility experts.

A: Is Mathjax accessible for people using screen readers?

davidlowrydudaMathJax provides an accessibility extension that works with a variety of screen readers. For more details concerning MathJax and screen readers, I suggest reading this link on accessibility features in MathJax. Often this is through MathML, as MathJax translates expressions to MathML internally. ...

The link in the post seems to be dead, here is some version from the Internet Archive. I suppose the new link is this: docs.mathjax.org/en/latest/basic/accessibility.html (Wayback Machine). — Martin Sleziak Jan 10 at 1:29

Q: Typesetting variants of sum and integral signs in mathjax

Manfred WeisIs there any way to enforce the lower and upper limits of integrals and sums to appear below and above the respective signs in MathJax (cf e.g. the German variant described here: https://en.wikipedia.org/wiki/Integral_symbol and https://tex.stackexchange.com/questions/170028/integral-sign-int)? ...

I you're looking to obtain this $\int\limits_0^1$ instead of this $\int_0^1 $, then just use "\limits" after "\int". — Zacky 25 mins ago
It seems that in centered formulas there is a difference between \int_0^1 f(x) dx and \int\limits_0^1 f(x) dx. (Actually, I did not know this until know - I only saw that in the Wikipedia article you linked.) Here is the comparison: $$\int_0^1 f(x) dx \qquad \int\limits_0^1 f(x) dx.$$ I am not sure whether this is what you're trying to get. (In the previous comment, Zacky also used \limits to get similar effect in the inline mode.) — Martin Sleziak 21 mins ago
@MartinSleziak I'm trying to get what's on the right; at least for out of line formulas. — Manfred Weis 16 mins ago
So I guess that the inline formulas you could try $\int\limits_0^1 f(x) dx$ $\int\limits_0^1 f(x) dx$ or $\displaystyle\int\limits_0^1 f(x) dx$ $\displaystyle\int\limits_0^1 f(x) dx$. (Which is basically the suggestion from the first comment. Personally, I avoid \displaystyle in inline formulas, but probably this is a matter of taste and writing style.) — Martin Sleziak 13 mins ago
Zacky and Martin, thanks for the helpful feedback; would either of you add that to the MathJax tutorial math.meta.stackexchange.com/questions/5020/… so that it doesn't get lost? — Manfred Weis 10 mins ago
Also for in-line sums (and products, etc.) \prod_{j=1}^5 T_j = \prod\limits_{j=1}^5 T_j $\prod_{j=1}^5 T_j = \prod\limits_{j=1}^5 T_j$. Also, in some styles of writing, we want ${}_a\!\int^b f(x)\;dx$. — GEdgar 10 mins ago
For other signs (not integrals) something like this works too I guess: $\underset{n=0}{\overset{\infty}\sum}f(n)$, produced by "\underset{n=0}{\overset{\infty}\sum}f(n)". But I wouldn't recommend using it. — Zacky 6 mins ago
@ManfredWeis Well, \limits are already mentioned there,in the answer about limits. I am not sure, maybe something could be added to the answer about displaystyle I'll leave editing of the tutorial to others. The MathOverflow Meta FAQ on MathJax has an example with sums. — Martin Sleziak 3 mins ago
@Zacky I think limits work just as fine with sums: $\sum\limits_{n=0}^\infty a_n$ $\sum\limits_{n=0}^\infty a_n$. Would you be willing to summarize some of the stuff mentioned in comments and post it as an answer? BTW we can also discuss this in the MathJax room, if we want to avoid too long discussion in comments. — Martin Sleziak 1 min ago

I'd rather not since from phone I find it rather hard to produce that gray area behind the code. And well, as you said \limits where already discussed in that linked post, not sure if an answer would add anything substantial. — Zacky 3 mins ago
