  9. Thestateof theart “Currently there is a complete mismatch between mainstream software for mathematics and existing screen readers when it comes to multimodal presentations of formulae.  In most cases formulae are printed on the screen using graphical glyphs.  Hence, learning environments are basically unusable for mathematics by people with disabilities such as dyslexia, dysgraphia, and any visual impairment.” Mika Seppälä, Florida State University
