Access to Mathematical Expressions in MathML for the Blind

For visually handicapped people virtual learning environments are a chance to participate in scientific education, because they can access the written content. However mathematical expressions rendered as raster graphics are not accessible to them. MathML, the web-standard for mathematical notation, provides the possibility to describe mathematical expressions in a textual form. However, it is not comfortable for this purpose because of its length and complexity. In this paper we present a transformation from MathML expressions into a compact mathematical notation for the blind (SMFB Stuttgart Mathematical Notation For the Blind). Finally, we show how we automate this transformation by integrating it into a virtual learning environment.
