[NTG-context] Re: PDFs for the visually impaired

Thanks Matthias - that's an excellent pointer to what has to be done (and part of me is wondering whether in a little while one will just instruct AI to read out the text logically in any case...).

You can try

\setupinteraction [page=yes, menu=on, state=start ]

\starttext

First \footnote[]{Footnote} Second

\stoptext

The PDF has the footnote tagged, but I don’t know what a screen reader will do with the tags.

Acrobat reads the document linearly, and one can navigate with the keyboard to the footnote and back.

In the document you linked to, Acrobat reads the text by including the footnote (the index 1 in the text and 1 in the footnote are read together as “eleven”). I don’t know whether that can be achieved in ConTeXt, or whether it is desirable. I'm also new to all this.

Visually impaired readers using an audio reader to access PDFs will want to have footnotes read out at the point of occurrence of the footnote cue, after which reading of the main text will resume. (Or some may wish to have the footnotes suppressed altogether, which ideally should be an option). Is that achievable in ConTeXt?

I have no experience of InDesign, but it seems that this happens automatically with PDFs produced by that program:

I was sent the Bulletin as an example of how German Historical Institute volumes should be formatted in future for compliance with the latest Accessibility legislation.
