[accessibility] Workshop at TUG2018 (20 July), example source TeX documents

Dear Colleagues,

Thank you very much, once again, for the invitation to present our package
and the accessibility project at TUGMeeting 2018, and to participate to your
round table on accessibility.

We would like to add a few remarks.

-  During Sandro's presentation, his Mac language was still set to Italian,
   while the screenreader's one was English, so the Latex code was (partly)
   read incorrectly. Please find here
http://www.integr-abile.unito.it/share/VoiceOver.mp4 a short video,
   that shows the correct reading of such code in English through VoiceOver
   and Adobe Reader DC.

-  We are aware that the PDF file obtained from pdfLatex using axessibility.sty
   still has some issues (as Ulrike Fisher noted), and it is not tagged. We are
   currently working towards a compliant solution, but our first main focus,
   as explained during the talk, was accessibility of formulae by screenreaders.
   Concerning this point, we would like to stress, once again, that having a PDF
   with formulae that can be read by VoiceOver, JAWS and NVDA is (by our
   testers' feedback) really an important improvement for visually impaired

- Concerning the more technical aspects of Ulrike Fisher's comment (namely,
  the overlapping with AccSupp), we already proposed on GitHub a solution
  that does not patch the original command. As soon as the test phase is
  completed, we will upload a new version of our package on CTAN (which
  will also cover more LaTeX commands for writing mathematical formuale).

To conclude: we believe that the alternate text of a formula should be
delivered in Latex.
This is a very flexible way to deliver the meaning of the formula
itself. The natural language and the semantic interpretation can be
left to screen readers'
dictionaries, add-ons and document Readers. This allows customization
of the language,  user's mathematical knowledge, scientific area, etc.
We are currently working on dictionaries for NVDA and JAWS which you
can find on our repository on GitHub.

Needless to say, we would be very grateful for any further comment/hint
by TUG members, aimed at improving our package functionalities and its
interplay with other LaTeX packages/accessibility tools.

Please find below the links to Sandro's talk in Rio, and 2 short
videos showing how VoiceOver, NVDA and Jaws behave with our package.




Thank you again for your support. Best regards,

Anna, Sandro, and the axessibility team
