[Tex/LaTex] Accessibility issues

accessibilitypdftex

Currently, I'm generating the following pdf with pdflatex: http://dl.dropbox.com/u/2682197/book.pdf

Unfortunately, this document is a bit incompatible with adobe screen reader (for blind people).

This audio recording demonstrates the result of using adobe screen reader with that document: http://dl.dropbox.com/u/2682197/speech.mp3

In the recording, it's impossible to hear the chapter or section headers.

Any ideas of how to build a "more accessible" document?

Your PDF doesn't has the right Character Map defined. You can see that when you copy an heading:

CucZ Z u«±§¶±¶§Z o £§u±

You have the same problem many people have, that you can't copy or search the text in the pdf. There are basically two different things you can use: cmap or \pdfgentounicode. How and when you should use which, is explained here by Heiko. I have found that it resolves all issues I had with copying and now I can even copy most math.

There is also the package mmap, which you can use instead of cmap. More is explained here

Try the following. And next time make an example with less fancy formatting. Concentrate on the problem.

\documentclass[a4paper,12pt]{article}

\usepackage[ansinew]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{libertine}
\input{glyphtounicode}

\pdfglyphtounicode{f_f}{FB00}
\pdfglyphtounicode{f_f_i}{FB03}
\pdfglyphtounicode{f_f_l}{FB04}
\pdfglyphtounicode{f_i}{FB01}

\pdfgentounicode=1
\begin{document}
ff fl ffi
\end{document}

glyphtounicode.tex should be in your texsystem in tex/generic/pdftex. But you can also find it in the texlive source: https://www.tug.org/svn/texlive/trunk/Master/texmf-dist/tex/generic/pdftex/glyphtounicode.tex

[Tex/LaTex] LaTeX accessibility

Try the \pdfcomment package. There's an option to add a tool tip to the PDF using \pdftooltip{item}{tooltip}, where the item can be a float (e.g. \pdftooltip{\includegraphics[]{}}{description of my figure}).

The overall process that I've settled on to produce 508-compliant documents is to

Produce a high-quality PDF from LaTeX which includes all of the tooltips
Run the PDF through the tagging tool that is provided by Adobe Acrobat X (Adobe how-to).
