Four Challenges • Access to mathematical content • Navigation in mathematical expressions • Presentation/Communication/Co-operation of mathematical information • Doing Mathematics (carrying out calculations and computations at all levels, doing formal manipulation, solving exercises) Paris 08, Klaus Miesenberger
1. Access: eDocuments More dimensional: • DotsPlus • ViewPlus • Triangle • Math Project Linear: • Aster • HRTeX/LaBraDoor • Lambda • MathProject • MahtTalk • MathGenie • TechRead • IGUMA • BraMaNet • Math2Braille • Infty • MMBT/Vicky Paris 08, Klaus Miesenberger
2. Navigation: problems • You will not easily understand a complex math expression by sequentially reading it • You need to scan passages of a formula repeatedly • You need to jump over irrelevant portions of a formula • Not every Braille notation makes structure of an equation immediate • … Paris 08, Klaus Miesenberger
Collapse/ Expand Paris 08, Klaus Miesenberger
3. Presentation/Communication • From MathML, LaTeX, OpenMath to Braille/Audio • Form Braille to MathML, LaTeX, OpenMath • From context sensitive to context free • Logic Programming • Synchronization visual / audio / Braille Paris 08, Klaus Miesenberger
Synchronize Paris 08, Klaus Miesenberger
