Hi Tom,


Can you forward this to the list for me?


I am not aware of a standard for alt text for math equations. What I have seen so far is that the 
alt text depends on the target audience. Many higher education institutions in Europe use LaTeX for 
equations, even though it is not a format developed with accessibility in mind. So in that context, 
using LaTeX as a text alternative is often considered acceptable. 

A few years ago, the @Science network (an EU-funded project) looked into this type of questions and 
gathered information on practices in Europe; you can find their guidelines at 
<http://www.ascience-thematic.net/en/guidelines>.
Another place to ask this kind of question - at least if you are on LinkedIn - is the Math 
Accessibility Professionals group on LinkedIn.


Exporting Impress presentations to PDF won't make them more accessible, quite the obverse, since 
text alternatives are lost: <https://bugs.freedesktop.org/show_bug.cgi?id=34135>.



Best regards,


Christophe

Hi :)
I have forwarded this to the accessibility list which is usually faster and better at answering 
these problems than the Users List.  

Unfortunately protonpusher is not subscribed to the Accessibility List (i think) so please CC 
replies directly to him/her.  

Thanks and regards from
Tom :)

I am looking for some guidance with math equations in Impress presentations, taking into account 
accessibility requirements. I am using LibreOffice on Ubuntu. Also a consideration is that the 
presentations would be converted to pdf as well.

My understanding is that description attached to the equation would serve as an alt tag when I 
convert to pdf. Where I am sort of stumped is what to put in the description. One though was to 
copy the Math markup to the description. However I am not actually sure how visually impaired 
students would be able to use this. I played around with Orca, but could not get it to read the 
equation in either the original Impress presentation, or in the pdf output.

So, 1) Am I going in the right direction putting the LO Math markup in the equation description, 
and 2) How would I read the description in the Impress presentation if I were visually impaired?
