IFLA 2016: EPUB and math accessibility

  1. 1. Steve Noble - University of Louisville Presenting on behalf of the DAISY Consortium 1 IFLA/LPD Satellite Conference August 2016
  2. 2. George Kerscher & Steve Noble (plus Nesbit) hiking in Missoula, Montana
  3. 3.  An Open Electronic Publishing Standard from the International Digital Publishing Forum (idpf.org)  Based on existing open standards, such as HTML5, MathML, SVG, CSS, etc.  Widely adopted in the ebook publishing industry  Transition to Inclusive EPUB 3 Ecosystem (TIES) is now being promoted by the DAISY Consortium
  4. 4.  DAISYTIES 2016 Survey results shed light on perception among libraries  29 DAISY members responded, but only 4 from “developing countries”  12 members have begun some level of EPUB 3 production  Only 6 have begun some level of EPUB 3 distribution
  5. 5. DAISYTIES 2016 Survey results indicated the “Top Reasons” that are delaying migration to EPUB 3 1. Lack of accessible reading systems (17 ranked this as “priority 1”) 2. Lack of production tools (7 ranked as “priority 1 or 2” 3. Lesser ranked issues: “users preferences” and “cost of migration”
  6. 6.  EPUB 3 Support Grid: http://www.epubtest.org/  A project of the Book Industry Study Group's (BISG) Content Structure Committee in partnership with the International Digital Publishing Forum (IDPF) and the DAISY Consortium.
  7. 7. Highest-rated systems for accessibility: 1.VitalSource Bookshelf (Windows, iOS, Android, Mac OS X) 2. Adobe Digital Editions (Windows) 3.Voice Dream Reader (iOS) 4.iBooks (iOS) 5.Gitden Reader (iOS) 6. Readium (Chrome in Windows) 7. Kobo app for iOS
  8. 8. A few things to note from the 2016 DAISYTIES survey:  38% of content is “leisure reading”  36% of content is “educational”  [Based on per capita production]  13 (out of 29) members high level of interest in adding MathML  12 members cited desire for extended description  11 members cited desire for supporting tactile diagrams
  9. 9. EPUB3 Readers that are Accessible + MathML support  IDEAL Group Reader (Android) apps4android.org – highly accessible, but not yet reviewed by BISG  Dolphin Easy Reader (Windows) - no BISG review yet  ReadHear PC Premium by gh (Windows) very accessible – no BISG review  VitalSource Bookshelf  Adobe Digital Editions  iBooks  Readium  See http://docs.mathjax.org/en/latest/misc/epub.html
  10. 10. • Key is MathML <math> <mroot> <mi>x</mi> <mn>3</mn> </mroot> </math> 10 3 x
  11. 11. • HTML5 • DAISY 3 • NIMAS • EPUB3 • PDF/UA • DocBook • Open Document Format (ODF) • AQTI (Test Question Interoperability) 11
  12. 12. 12          2 2 2 1 4 x x f x x x x      Made possible via MathType and MathPlayer Works in EPUB, Powerpoint, Word, Web, PDF energy 2 2 6 12 6 26CO 6 H O C H O 6O  
  13. 13.  AppleVoiceOver  Safari on Macs, IPads, Iphones (has Braille support)  ChromeVox  Chrome OS (CromeVox); Chrome browsers on all platforms  JAWS 16 +  IE and Firefox | Braille support in JAWS 17 |Pre-16 = MathPlayer  Windows  MathPlayer + NVDA (has braille support)  MathPlayer +WindowEyes (no math braille); many other AT also  Works in IE or Firefox onWeb; also math inWord, PowerPoint, … 13
  14. 14. http://msf.mathmlcloud.org/ 14
  15. 15. • MathType :Word, iWork, … • Wiris: Web-based MathML editor • MathFlow: ArborText, XMetaL, XMAX • Open Office • Scientific Notebook • TeX→MathML:TtM,TeX4ht,LaTeXML, MathJax • Mathematica, Maple, MathCAD • Central AccessToolbar • MathML Cloud :Web-based or API/source code for building into automated processing 15
  16. 16. • The problem: cross-browser, cross-platform support for native MathML in web pages • The solution: a JavaScript display engine with accessibility support called MathJax • Limitations: (1) JavaScript must be enabled…not an option for DAISY books, but fine for EPUB; (2) requires either a live internet connection, or a local installation of MathJax library • Website link: https://www.mathjax.org/ • MathJax 2.6 Accessibility: http://docs.mathjax.org/en/latest/misc/accessibility- features.html • MathJax Accessibility extensions: https://github.com/mathjax/MathJax-a11y/wiki/MathJax- Accessibility-Extensions-Documentation
  17. 17. • Math expressions inWord documents can easily be read and navigated with the right AT, even without exporting. • How??  MicrosoftWord stores math in MathML. • Method 1: Use MathType + MathPlayer + NVDA or WindowEyes • Method 2: Use Central Access Reader (self-voicing; works inWindows or Mac)
  18. 18. • Good News:Yes! Math images can be inserted on the page and MathML code embedded in a <formula> tag [This is part of the PDF/UA standard] • Not so good news: NVDA onWindows (with MathPlayer installed) is the only AT that can currently read this. • Bad news: At this time, none of the PDF authoring/conversion tools automate this process. For each expression, the MathML code must be created in another application and copied/pasted into a <formula> tag.
  19. 19.  Tools from inftyreader.org  InftyReader – Math OCR software (standalone or as an ABBYY plug-in) – Data conversion (LaTeX, MathML, Word XML)  InftyEditor – Free editor of math documents including math handwriting recognition  ChattyInfty – InftyEditor + speech output – Authoring and editing tool of math documents for visually impaired users
