Employing semantic analysis for enhanced accessibility features in MathJax

Recent changes in the landscape for assistive technology solutions for Mathematics on the web have prompted the development of MathJax into a single rendering and accessibility solution. We present our current efforts that depend on a novel semantic interpretation of Presentation MathML expressions. This allows us to introduce a new notion of responsive equations, on which we build advanced accessibility features with improved reflow of content, selective highlighting, and dynamic speech text generation, as well as an innovative interaction technique based on abstracting and intelligently summarising sub-expressions.
