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

Accessible Image ExampleAbout 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.

The Case for MathML
●Standard for math gaining traction globally ●National Instructional Materials Accessibility Standards Center recommends:
...MathML be used to improve the accessibility of mathematical and scientific content in core instructional materials ...as the most effective method of providing accessible print instructional materials involving mathematical and scientific content to students who are blind or who have print disabilities.
●Tools for accessible MathML rendering getting better

Discovery of Accessible Resources
● Accessibility Metadata Project
Page 20
Accessibility Metadata
● Metadata that tells users about accessibility features in content
● Helps users find content that works for themhttp://a11ymetadata.org
● Early adopters in place now

Discoverability Benefits of Accessibility
● Detailed image descriptions can be indexed and searched
● Registry or repository of accessible materials can be shared
● More upfront accessibility means easier and more widespread distribution
● Different modalities benefit everyone!
