Evaluating solutions to process, view and listen mathematical formula within an accessible context

  1. 1. Mireia Ribera, Miquel Centelles, Alberto Huélamo, Bruno Splendiani, Marina Salse ULD Conference 2013 - 13/02/2013
  2. 2.  LIS Department – University of Barcelona (Spain)  Group Adaptabit: Working group on digital accessibility for teaching, research and teaching innovationFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  3. 3.  Background Issue Proposal Methodology Further workFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  4. 4. Accessible teaching documents project Every educational institution must ensure access to the information for all students Goal: Promote equal opportunities / full integration into university academic life by the use of accessible materials in academic community Provide templates for the creation of most widespread teaching documents, and easy procedures to create alternate versions of them.February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  5. 5. Outputs “Guides for creating Accessible Digital Contents” Templates ▪ Teaching documents in academic community (exams, exercises, tutorials, lessons and slides) ▪ Best format suited to each context (Office, PDF, LaTex…) ▪ Adaptation to the needs of blind and low vision students and students with dyslexiaFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  6. 6. Templates for the conversions to accessibledigital formats, but Mathematical notation / formulae present specific accessibility barriers and impose specific requirements in conversion Why?February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  7. 7.  Most word processors process mathematical notations/formulae through a codification system or graphical formats procedures. Not suitable for assistive technology (e.g. JAWS, Zoom Text) Consequences  Barriers to blind and low-vision people  Barriers to people with dyslexia or Attention- Deficit Hyperactive Disorder (ADHD)February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  8. 8.  Solution: MathML  XML language for the markup of mathematical formulae  Renderized audio of electronic documents  Expressions magnifiers (low-vision users)  Limitations ▪ Mathematicians writing on text processors or in LaTex, not in MathML ▪ MathML not fully supported by browsersFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  9. 9.  Test which text editor/LaTex and browser best creates and renders mathematical formulae in MathML  Obtain evidences of capability on writing mathematical formulae  Obtain evidences of capability and quality on viewing and listening to mathematical formulae.February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  10. 10. February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  11. 11.  Testbed was designed with two main components:  Catalogue of a selection of 139 different formulae (LibreOffice Math 3.3.2)February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  12. 12.  Three text processors + one LaTex editor with specific capabilities for processing mathematical notation  Text processors ▪ MS Word 2007 (12.0.6661.5000) SP3 MSO (12.0.6662.5000) ▪ MS Word 2007 ▪ MS Word 2007 with MathType 6.0 (DesignScience) ▪ LibreOffice Math 3.3.2  Latex editor ▪ MiKTeX 2.9 TeXnicCentre 1.0 The most used editors by faculty members of UB February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  13. 13. Results of the formulae processed with theeditors were converted into MathMLFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  14. 14.  To view and listen on different internet browsers the results of conversion to MathML Visualization  Firefox 12.0 (Win)MathML native support  Opera 12.02 (Win) MathML native support  Safari 6.01 (Mac) MathML native support Visualization and Listening  Internet Explorer 8 ( + MathPlayer Plug-in)February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  15. 15. Two different indicators Visualization review  Quality of displays values  Not acceptable display;  acceptable display;  best display Listening review  Quality of reading(Mathplayer options : Spanish language / Reading for the blind)  MathPlayer doesn’t read the formula;  MathPlayer reads the formula partially;  MathPlayer reads the formula correctly February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  16. 16. MS Word empowered with MathTypebest solution in terms of number of symbols correctly interpreted quality of displays for visualization quality of readings for listening Strengths  the high quality in visualization of big operators (sum, prod, coprod…) and resizable delimiters  Better results even compared to LibreOffice Limitations  6 mathematical expressions not rendered (out of 139)February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  17. 17. LaTex 11 mathematical expressions not rendered (out of 139) By default LaTex exports formulas in a nonstandard typography  limitation in viewing and in Mathplayer listeningFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  18. 18.  IE+MathPlayer visualization of expressions processed by MSWord 2007+MathType is the best solution Firefox is the better browser without plugins Opera lowest performance Safari quite good, but bad performance with accentsFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  19. 19.  Best results on IE+MathPlayer is MS Word 2007+MathType LaTeX MiKTeX 2.9 + TeX2ht lower performanceFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  20. 20.  Recommendations addressed to University professors (research based) Manuals for the creation on how to convert Latex formulas and how to create formulas with MathType Share results data Conversion from paper (Inftyreader)February 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
  21. 21. Questions Opinions Suggestions… splendiani@ub.eduFebruary 2013 Adaptabit (adaptabit@ub.edu) http://bd.ub.edu/adaptabit
