When “alt text” is not enough
Adding alt text to images is an important part of making images accessible to those with print disabilities. But, what should you do when you have a complex image whose meaning cannot be conveyed with alt text alone? Whether you are a professional publisher, a web developer, or a teacher creating digital handouts for your class, you can find resources here to make it much easier for you to make complex images accessible to all readers.
The Leading Edge of Accessible Images and Math
Tactile images, sonfication, 3D printed images, and haptics are just a few of the ways you can make digital images accessible. Take a look at DIAGRAM research and development that anticipate the future of accessible images using smartphones, tactiles, and templates. Read testimonials from members of the DIAGRAM community who are part of our working groups and who have taken our webinars.
Tools and Tips for Creating Accessible Images
- Poet, the open-source image description tool allows anyone to attach image descriptions to DAISY format books. Volunteers have now written more than 40,000 image descriptions for DAISY books using Poet.
- The DIAGRAM Center is exploring 3D printing technology as a way to increase access to curriculum and learning for all.
- DIAGRAM’s “Top Tips for Creating Accessible EPUB 3” have been adopted by the Association of American Publishers.
- Free training webinars on image description have reached hundreds of publishers, educators, and content technologists.
- Our Accessible Image Sample Book provides concrete examples of what accessible images look like in context. Code samples are also included so that you can see how you can create accessible images in your own books.
Making Math Accessible
- “Math Helper” (part of Poet) transcribes math into machine-readable format (MathML).
- Free webinars on how to create accessible math such as “Tools for Creating Accessible Math” and “Digital Accessible Math Images.”
- Get a peek at the future by reading about DIAGRAM’s research partnerships with leading technologists on the future of math accessibility.
- The Accessible Image Sample Book contains examples of innovative yet simple ways to make graphs and equations accessible to all readers.
