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

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 billion
in new edtech financing in 2012
2,500%
more expensive to retrofit for accessibility from print
(or print equivalents)

9. What is an Accessible Image?
●
Provides different
mode of access to
visual information
contained in an image
●
Beyond just alt text!
Page 9
10. 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

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.

You can add long
descriptions to
HTML 5!

13. 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 MathPlayer plugin
●
But steps backward as well
– Chrome dropped MathML support
– IE 10 & 11 do not support MathPlayer plugin

14. Stopgap Math Accessibility Solutions
●
MathJax JavaScript library for 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

15. Interactive Content / Widgets
●
Simulations
Interactive Number Lines
●
Quizzes
●
3D models

16. How Can We Discover Accessible eBooks?
Page 16
20. 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-accessibilitymetadata/
Page 20
21. What can you do?
1. Leverage standards, such as HTML 5, WAIARIA, EPUB 3
2. Build content creation tools that make
accessibility easy
3. Create reading systems that are accessible
to use, leverage standards and build on open
source projects like Readium

Editor's Notes
Explain what a print disability ishttp://readingrights.orghttp://www.who.int/mediacentre/factsheets/fs282/en/: number of people with vision impairmenthttp://www.insidehighered.com/news/2013/05/09/berkeley-agrees-do-more-help-disabled-students-do-homework-and-research : increase at UCB
Organizations like Bookshare and UC Berkeley’s DSS cannot scale convert this explosion of content into accessible content.The solution is that..
… and stay that way…
Image: Screen shot of a biology book shown in the Bookshare Web Reader. There are two viewing panes. The left hand pane shows a well ordered structure of headings and sub-headings, going four layers deep, all selectable. The right hand pane shows an image with a description, an active link, and reflowable text.Around the image are tips for accessible content:Structure: Navigation, SectionsImages: Longdesc, DiAGRAM Content ModelText: Reflowable, Style/Content, FormattingMath: MathML, DescriptionTables & Lists: Headers, OrderingVideo: Track: subtitles, description, etc.
Images:Collection of 4 complex images from the textbook CK-12 Biology I.
Image:Sample tactile graphics being explored by users at DIAGRAM meeting.
This is an example that illustrates the DIAGRAM Content Model.Image:An image depicting the hydrologic cycle. The text items on the slide are examples of alternative descriptions of the graphic content. An additional callout balloon pointing to “Long Description” reads “You can add long descriptions to HTML 5!”
Image:Screenshot showing browser with two main vertical panels. Left panel is 25% of the screen and contains list of images, each accompanied by a dropdown. The left panel takes up the rest of the screen. It contains text followed by an image in a box. Next to the image is an editable box that holds the image description.
NIMAC: National Instructional Materials Accessibility Standards Center recommends MathML 3 in June 2012.
