DIAGRAM Center: Making Image and Graphical Content Accessible

EASI Webinar – August 8, 2012


A little about us
A Little About Us… Accessible

  • 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



Diagram created to meet those challenges
DIAGRAM Created to Meet Those Challenges Accessible

  • 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


What s an accessible image
What Accessible ’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


Diagram goals
DIAGRAM Goals Accessible

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)


Make Accessible “born digital”mean

“born accessible”


What is the diagram center
What is the DIAGRAM Center? Accessible

  • 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


Who else is the diagram center
Who else is the DIAGRAM Center? Accessible

  • 27-member Advisory Board

    • Technologists

    • Educators

    • Publishers

    • Accessibility experts

    • Student/Parent reps

  • Working Groups with 20+ members

  • Collaborators including Image Share, DorinaNowill


What we ve done tools
What We Accessible ’ve Done: Tools

  • Poet: A Tool for Crowdsourcing Descriptions

  • Image Accessibility Coverage Checker for DAISY Books

  • Tobi integration: DAISY tool for multi-media production


Poet a tool for crowdsourcing descriptions
Poet: A Tool for Crowdsourcing Descriptions Accessible

  • 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 math helper
Poet: Math Helper Accessible

Converts ascii math input into MathML and MathJax


Poet bookshare use case
Poet: Bookshare Use Case Accessible

  • Bookshare actively using Poet to add image descriptions to textbooks

  • Thousands of images described by

    • Volunteers

    • Vendors

  • Provides user feedback to influence new development


What s next tools
What Accessible ’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


What we ve done standards
What we Accessible ’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


Standards content model
Standards: Content Model Accessible

  • 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.)



Standards content model example
Standards: Content Model Example Accessible

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.
