DIAGRAM Tools
In keeping with the DIAGRAM Center goal of dramatically changing the way image and graphic content for accessible instructional materials (AIM) is produced and accessed, DIAGRAM both creates tools and partners with other organizations to develop tools that achieve this goal.
POET Image Description
Poet is an open-source image description tool that allows crowdsourcing of image descriptions to reduce cost. It includes a feature called Math Helper to transcribe math into a machine-readable format (MathML).
MathML Cloud
MathML Cloud is an open-source tool that makes it faster, easier, and cheaper for traditional publishing houses and authoring platform providers to create math content that is accessible to all readers.
WAVES
WAVES (Web-Accessible Virtual Electronic Scratchpad), developed by gh, LLC under a grant from the DIAGRAM Center, is a small Windows application that provides accessible math input and output for blind and visually impaired users.
TGV
Tactile Graphics with a Voice (TGV) is a GR-code reading app that allows text within images to be read and voiced by a mobile device such as an iPhone or Android phone.
Standards & Guidelines
The DIAGRAM Center will publish information regarding standards and best practices as they relate to creating and accessing image descriptions. This page is an index to that information.
Diagrammar
Diagrammar is a framework for making images and graphics accessible. It provides a structured way for image description data to be modeled, including multiple different types of descriptions for each image, teacher annotations, and pointers to tactile and graphic files.
Accessible Image Sample Book
The Accessible Image Sample Book provides a variety of concrete examples that show you how digital images can be made accessible, including sample code that you can use to make it easier to create accessible images in your own digital publications.
Image Description Guidelines
These guidelines were born from a partnership between the DIAGRAM center and the Carl and Ruth Shapiro Family National Center for Accessible Media at WGBH (NCAM). The guidelines cover general recommendations as well as guidelines for describing specific types of images, such as maps or graphs.
