A Little About Us…
● Benetech: Technology Serving Humanity
● Anh Bui, Senior Manager of DIAGRAM Center● Fred Slone, Director of Operations, Bookshare
● DIAGRAM Center and Bookshare are part of Benetech’s Literacy Program
Page 3
Images are Challenging (especially STEM)
Page 4
DIAGRAM Created to Meet Those Challenges
● Revolutionizing access to images and graphics in educational content through technology:– Tools
– Standards
– Best Practices & Research
● Make creating and using accessible images easier, faster, more cost effective
● So students can have timely access to the information they need
Page 5
What’s an Accessible Image?
● Provides different mode of access to visual information contained in an image, e.g.:– Text/audio description
– Tactile graphic
– Sonification
– Smart image
– Multi-modal access
Page 6
DIAGRAM Goals
Make it easier, faster, and cheaper to make and use accessible images so that students with print disabilities have timely access to the information they need.
In other words:●Make it easier for content producers to create accessible images
●Make it easier for consumers to use accessible images via technology
●Make it easier for both producers and consumers to discover accessible images and tools
●Make it easier for both to interact with content that need not be stored as traditional or static images in the first place (e.g., mathematical equations)

What is the DIAGRAM Center?
● 5-year Research & Development Center ● Funded by Department of Education, Office of
Special Education Programs (OSEP)● Awarded to Benetech along with partners:
– NCAM
– U.S. Fund for DAISY

What We’ve Done: Tools
● Poet: A Tool for Crowdsourcing Descriptions● Image Accessibility Coverage Checker for DAISY
Books● Tobi integration: DAISY tool for multi-media
production
Page 11
Poet: A Tool for Crowdsourcing Descriptions
● Web-based and open source for adding image descriptions to eBooks (DAISY)
● For use by authors, publishers, accessibility providers
● Designed to:– Quickly identify all images in an eBook
– Tag images needing descriptions
– Author and edit rich descriptions
– Provide guidance to describers (guidelines)
– Moderate and approve descriptions
– Integrate with content production tools

Poet: Navigation, Contextualize, Describe
Page 13
Poet: Math Helper
Converts ascii math input into MathML and MathJax
Page 14
Poet: Bookshare Use Case
● Bookshare actively using Poet to add image descriptions to textbooks
● Thousands of images described by– Volunteers
– Vendors
● Provides user feedback to influence new development
Page 15
What’s Next: Tools
● Poet– EPUB 3 and Content Model support
– Improved UI
– More Math and STEM support
– Image Classification
– Field testing with educators
● Image Accessibility Coverage Checker for EPUB 3● Prototypes:
– Interactive Image Description/Tactile Graphic Decision Tree
– QR Codes for Tactile Annotations
– Simplified Math Notation System
– More!
● Multi-modal access
Page 16
What we’ve done: Standards
● Advocacy for description-related mark up in web and ebook standards
● DIAGRAM Content Model: – Framework for how to think about accessible images
– Standard means that we can share metadata about images across systems
– Groundwork for giving individuals different ways of getting information from the same image
Page 17
Standards: Content Model
● XML data model for image metadata● For given image you can have:
– multiple types of descriptions (e.g., short, long, simplified etc.)
– alternative image links (e.g., SVG)
– other image metadata (e.g., target age, grade level, etc.)

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.

What’s Next: Standards
● EPUB 3 Accessibility– Collaborating on EPUB 3 accessibility checklist
– Update Matt Garrish’s “Accessible EPUB 3”
● Continued advocacy, monitoring progress● Reference implementations and guidelines● Exploring integration opportunities with other
standards
Page 21
What we’ve done: Best Practices & Research
● Training webinars● Product evaluation matrices● User survey on reading technologies● Report on metadata images
Page 22
What’s Next: Best Practices & Research
● SVG and 3D Printing evaluation● Audio-tactile (i.e., text-tactile) usability study● Collaboration with Mathematics eText Research
Center (MeTRC, University of Oregon)● Interviews with content providers ● End-user survey follow up activities● Advocacy for efficacy research
Page 23
What’s Next: Longer Term
● Some of the areas under exploration:– Technology for tactiles
– Haptics
– Interactives and Image exploration
● Extended International Reach● Sample Content● Coordination with efforts in assessment

Our Accessible Image Initiative
● Launched in late fall 2011, started from zero● It takes time & staffing● “Re-launched” in early 2012● A few volunteers did nearly all early descriptions
AS OF JULY 2012: ● 21,000 image descriptions created● 16 described textbooks, including two STEM
related● Nearly 50 active describers
Page 28
Lessons Learned / Important Stuff
● The 80/20 Rule (more like 70/20/10)● Recruiting● On Boarding & Training● “Image Slams” – Focused, ½ day events● Examples, examples, examples● Quality Control● Volunteer Burn Out● “Why should I care?”
Page 29
It is Art and Science
● Long vs Short Descriptions● Color vs No Color● Emotions and subjectivity● How much context● Learning objective vs not giving away the answer
