  1. Born Accessible Books in BrowsersOctober 25, 2013

  2. What is Accessibility for Print Disabled Students? Jessica, Steffon and Shane are three of 250,000+members who can access Bookshare’s library of 210,000+ books, textbooks and periodicals with reading tools tailored to their special needs http://youtube.com/watch?v=sUMmzi3nmig

  3. Challenge: The Need 30 million Americans with print disabilities 15-20% in U.S. have language-based disability 285 million people with vision impairment worldwide 115% More requests for alternative materials at UC Berkeley in 4 years

  4. Challenge: Everyone’s a Content Creator $1.1 billionin new edtech financing in 2012 2,500% more expensive to retrofit for accessibility from print (or print equivalents)

  5. A Critical Strategy All materials Born Digital Must be Born Accessible

  6. Accessible Content Highlights Images Descriptions Multi-modal (touch, sound) Structure Navigation Sections Text ReflowableStyle/ContentFormatting Math MathML Description Widgets ARIA Multi-modal Video Track: subtitles, description, etc. Tables & Lists Headers Ordering

  7. Images are Challenging (especially STEM)

  8. What is an Accessible Image? • Provides different mode of access to visual information contained in an image • Beyond just alt text!

  9. SVG Is Ideal for Accessibility • SVG can contain textual and structured descriptions and data • http://describler.com • http://d3js.org/ • Author with SVG and if need be distribute as PNG/JPEG • SVG can more easily be turned into tactile graphics • SVG has potential to be 3D printable • SVG can be sonified • http://svg-sonifier.com • http://github.com/benetech/svg-sonifier

  10. STEM Descriptions Need More than 120 chars About this description Author: John Doe, Ph.D. in Water Engineering Target Age: 9-12 Target Grade: 4-7 Summary The image depicts the cycle of water evaporating, turning into clouds, falling back to earth in the form of precipitation and being filtered through sediment. Long Description The image depicts the natural process of evaporation and precipitation and how rain water gets filtered and cleansed through the earth's sediment. On the left-hand side of the image is a lake... A weather event such as a rainstorm eventually returns the precipitation to the ground... The natural filtering agents in the soil... Annotation added by teacher In the winter we get snow instead of rain. Simplified Language Description The image shows how water becomes clouds, then rain, and then gets cleaned by the soil. Tactile Image [Tactile image] In the upper left corner of the tactile… Simplified Image [Simplified image] Moving front the top left corner of the image You can add long descriptions to HTML 5!

  11. Poet: Crowdsourcing Image Descriptions

  12. Mathematics • MathML support is taking steps forward • Safari and Firefox visually render MathML • Aural rendering in Safari, Chrome(Vox) and is coming in NVDA • Visual and aural rendering in IE 9 with MathPlayerplugin • But steps backward as well • Chrome dropped MathML support • IE 10 & 11 do not support MathPlayer plugin

  13. Stopgap Math Accessibility Solutions • MathJax JavaScript libraryfor all browsers • MathJax + Chrome(Vox) on the server as a web service • Input: MathML or LaTex • Output: SVG with embedded descriptions or PNG/JPG with alt descriptions

  14. Interactive Content / Widgets • Simulations • Interactive Number Lines • Quizzes • 3D models • http://www.w3.org/community/stemwidgets

  15. How Can We Discover Accessible eBooks?

  16. Schema.org Can Provide an Answer

  17. Recipe HTML 5 Tagging Example <div itemscopeitemtype="http://schema.org/Recipe"> <div itemprop="nutrition” itemscopeitemtype="http://schema.org/NutritionInformation"> Nutrition facts: <span itemprop="calories">240 calories</span>, </div> Ingredients: - <span itemprop="ingredients">3 or 4 ripe bananas, smashed</span> - <span itemprop="ingredients">1 egg</span>

  18. Accessibility Properties http://a11ymetadata.org

  19. Google Custom Search Example Search for “history” titles on Bookshare filter by presence of image descriptions: http://www.a11ymetadata.org/bookshare-tags-over-195000-titles-with-accessibility-metadata/

  20. What can you do? Leverage standards, such as HTML 5, WAI-ARIA, EPUB 3 Build content creation tools that make accessibility easy Create reading systems that are accessible to use, leverage standards and build on open source projects like Readium Hack – http://github.com/benetech http://bornaccessible.org
