Hi Tom and Roger,

The Math markup must be set in the description, which can be read by screenreaders as an alt attribute of the image of the equation. I do not have any experience with Orca. As I understood it must work fine with JAWS. You can try NVDA too. The problem is that each screen reader has its own way to show the description. It also differs per version of the software. You can also try Adobe Pro which gives you a good insign in the accessibility of the document.

Kind regards, Jaap

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

Subject: [libreoffice-users] Math and accessibility for the visually impaired
Date: Tuesday, 10 April, 2012, 5:01

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?
