We present an overview of the accessibility features of the new release of MathJax, a library for rendering mathmatical formulas on the web. We demonstrate how to convert mathematical teaching material into web content that can be rendered with MathJax and automatically be made accessible for students with visual impairments and dyslexia.


With more and more mathematical teaching material being made available online, its accessible representation is a major concern. And while formulas on the web can be represented in MathML, no major browser completely implements this standard. Consequently the MathJax library that provides a solution to render Mathematics in any browser, has become a quasi-standard for displaying Mathematics on the web.

As MathJax has undergone a major reimplementation effort over the last two years we will present the accessibility features provided in the new version, which include:

* Automatic voicing of formulas * Interactive navigation with synchronised highlighting * Different collections of speech rules like MathSpeak and ClearSpeak * Nemeth Braille output

We will also demonstrate how mathematical teaching material can be converted into web documents renderable with MathJax, and how the preservation of the original LaTeX sources can lead to an improved accessibility experience.
