2 Outline The Good Accessible Math MathML & Standards Authoring Tools Renders DAISY The Bad – Limitations The Ugly – Making it Work The Discussion…

3 Accessible Math What Expressions, Graphs, Figures, Animations, Manipulatives Where Textbooks, homework, articles, work Web, MS Word, PDF, ebooks Why Every day, every student takes math It is one of the 3 "R"s Its the Law…

4 Accessible Math Requirements Blindness Audio description Navigation Braille math translation Low Vision Font size and color control Print-related Learning Disabilities Synchronization of highlighting with speech

5 Math as Images Whats Wrong with Images Math can and is spoken many different ways Alt text is static Pronunciation: a plus b No magnification, navigation, braille, or sync highlighting MathML to the rescue…

6 MathML Example Presentation x 3 Content 3 x

7 MathML In Standards MathML 2 (2003); MathML 3 (2010?) DocBook DAISY (Digital Talking Books) NIMAS: K-12 Textbooks eBooks: ePub (OEBPS) PDF (?!) PDF/UA support for Math HTML5 (2012???)

8 Authoring MathType Word, iWork, … WebEQ Java-based MathML editor MathFlowArborText, XMetaL, XMAX Open Office Scientific Notebook TeX MathML TtM, TeX4ht,LaTeXML Mathematica, Maple, MathCAD

9 Design Science Authoring Tools MathType WYSIWYG TeX editing Works with Word PowerPoint iWork 09 Wikipedia…

10 WebEQ & MathFlow Editor Single Equations WebEQ Content MML XML Editors MathFlow Arbortext XMetaL SDK – suite of tools for custom apps

11 MathType & MathPage MathPage for Word Word-> XHTML MathPlayer Display Interaction Accessible

12 Works in Popular Browsers IE+MathPlayerFirefox

13 MathPlayer Accessibility Features Display Matches font size and color Allows magnification of expressions Synchronized highlighting Speech Supports multiple speech styles Supports multiple languages Supports prosody (pauses, rate, …) Braille Supports multiple MathML-to-braille translators DotsPlus (emboss to Tiger printers)

14 Demo Time Word+MathType MathPage to get XHTML+MathPlayer MathPlayer Accessibility

15 MathPlayer Multilingual Speech Translations Usable: Chinese, German, Greek, Italian, Japanese, Spanish, Swedish In Process Bulgarian, Czech, Dutch, Korean What it takes to do a translation ~150 words + 74 descriptions 3,000 Unicode characters (~500 needed)

16 DAISY DAISY is a highly accessible format Collection of files Audio, Text, or a combination Contains a MathML extension Used by Other Standards NIMAS is a subset of DAISY Part of ePub (ebooks)

17 Word & Save as DAISY Version 2: Full DAISY book Uses MathType Uses MathDaisy Demo… Edit (WYSWYG, TeX) SAD Also Open Office Add-in

18 The Bad: DAISY Only two visual players support Math gh Player Dolphin EasyReader v4 (+)Works with all Audio only players Not much technical material in DAISY Multiple files complicates delivery

19 The Bad: MathML on the Web Not Universally Supported Doesnt work in Safari, Chrome Doesnt work in IE w/o MathPlayer Accessible only w/MathPlayer or FireVox Fonts JavaScript and/or Greasemonkey-like solutions coming

20 The Ugly: MathML on the Web Serving XHTML application/xhtml+xml Use.xht as suffix dessci.com/en/products/mathplayer/author/creatingsites.htm UMM – PHP server solution MathML-aware browser MathML Otherwise Generate & Send Image GTKMathView (free) or MathFlow SDK umm.sourceforge.net

21 Summary Authoring: MathType, MathFlow, … Works with DAISY tools Display: MathPlayer, Firefox, gh Player, EasyReader Flexible Speech & Braille Generation MathML used in lots of places Project SMART: MathML is good
