Notas do Editor

  • Accessible Images: Challenges:
    Expertise
    Lack subject-matter expertise
    Not familiar with accessibility & standards
    Individuals possess varying levels of expertise
    Time and Cost
    Time to find references
    Time to get trained up on best practices
    Time and cost required to produce content
    Cost-benefit: limited user reach when produced adhoc
    User-Centric Resources & Guidelines
    Lack guidelines for a broad range of image types
    Minimal examples produced by experts
    Confusing standards that are constantly evolving
    Unsure how to incorporate new technologies
  • Word and HTML version of DIAGRAM Image Description Guidelines available at: http://diagramcenter.org/table-of-contents-2.html#book
  • Decision Tree developed through DIAGRAM subcontract with Touch Graphics; available at: https://diagram.herokuapp.com/training/when_to_describe
  • Video demonstrating how the interactive series of questions that takes users through the decision of when a text-based or alternative mode is needed for an image/diagram.
  • General guidelines that apply when writing descriptions for any image/diagram
  • Table of General Style Guides:
    Style & Language
    Context is Key
    Consider Your Audience
    Be Concise
    Be Objective
    General to Specific
    Tone & Language
    Formatting & Layout
    Insets
    Page Layout

    Example of a general guideline for Consider Your Audience
    General Guidelines:
    Know your target reader (e.g. age, culture, subject-matter expertise).
    Use vocabulary and phrases appropriate for the reader.
    Reference examples and details that the reader will understand (this includes objects and attributes used in the description).
    Description: this is a photograph of the Louvre Museum in France at night. The entrance to the museum is a large pyramid made out of glass.
    Image in Context:
    This photograph of the Louvre is part of an introduction to a chapter in a history textbook for young children.
    The description uses language and introduces shapes appropriate for a young child.
  • Additional, self-paced resource allowing users to practice writing image descriptions, developed in collaboration with NCAM (National Center for Accessible Media).

  • Expanded from 10 to 26 “Image Types”, expanding beyond STEM to include templates for images such as maps, photos, and art. Also applied categories for grouping ease.


  • The practice writing section also provides template-based description guides from Touch Graphics and MathTrax.
  • A solution that supports visual rendering across a range of platforms/browsers:
    Browser 1: PNG by TeX on Firefox
    Browser 2: MathML by browser on Firefox
    Browser 3: MathML by browser on Chrome or IE
    Sample equations pulled from Mozilla’s “MathML Torture Test”: https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/MathML_Torture_Test?redirectlocale=en-US&redirectslug=Mozilla_MathML_Project%2FMathML_Torture_Test
  • Sample math equation with Firefox from: http://www.maths-informatique-jeux.com/blog/frederic/?post/2015/05/06/MathML-Accessibility
    Visual rendering of equation from MathJax website: https://www.mathjax.org/
  • MathML Cloud is available at https://mathmlcloud.org
  • Math Support Finder [BETA] is available at: http://msf.mathmlcloud.org/
  • Next step after the production of accessible math content is to help users discover what tools can be used to read math accessibly.
  • Search according to tools used by the end-users. In this example, two results are returned when searching for configurations using Word (desktop).
