Wikipedia is using a new approach for rendering mathematical formulae – as of May 31st. This approach was developed by our group member Moritz Schubotz.
Bitmap images representing formulae, were replaced with a combination of MathML (the web standard for mathematics on the web), in addition to a fallback mechanism for browsers that do not support this web standard.
This approach makes formulae machine readable and accessible to users with limited vision, while also looking crisper on high resolution displays and in print.
