The American Foundation for the Blind (AFB) is a national nonprofit that expands possibilities for people with vision loss. AFB's priorities include broadening access to technology; elevating the quality of information and tools for the professionals who serve people with vision loss; and promoting independent and healthy living for people with vision loss by providing them and their families with relevant and timely resources. AFB's work in these areas is supported by the strong presence the organization maintains in Washington, DC, ensuring the rights and interests of people with vision loss are represented in our nation's public policies.

In addition to its New York City headquarters and Public Policy Center in Washington, DC, AFB maintains offices in Atlanta, Dallas, Huntington, WV, and San Francisco. AFB is also proud to house the Helen Keller Archives and honor the over forty years that Helen Keller worked tirelessly with AFB to expand possibilities for people with vision loss.

Please address all questions to the Chairperson of BANA, who will then see that they are forwarded to the proper technical committee.
BANA has established "technical" committees composed of transcribers, braille readers, and educators whose purpose is to update the braille codes, formats, or techniques. These changes, which may be suggested by readers, transcribers, and/or producers are carefully studied. Proposed new codes or revisions are submitted to other technical committees to avoid conflict with existing braille codes. The BANA Board issues final approval for adoption and dissemination.

The Math Description Engine (MDE)
The Math Description Engine Software Development Kit is freely available to and can be used by software developers to make computer-rendered graphs more accessible to blind and visually-impaired users. It has a simple API that lets you easily add alternative text and sound descriptions to your graphs. Version 1 of the MDE SDK generates text descriptions for 2D graphs commonly seen in math and science curriculum (and practice). The mathematically rich text descriptions can also serve as a virtual math and science assistant for blind and sighted users, making graphs more accessible for everyone. Use the Math Description Engine to make graphing calculators, data analysis programs, computer simulations, or webite displays more accessible.

MathTrax is a graphing software that is accessible to blind and vision-impaired students. It supports critical math, science and technology learning objectives, and makes teaching and learning about science and math more accessible, fun, and easy for everyone! It describes graphs three ways - with "smart" text descriptions, nonverbal sound descriptions, and custom graphics descriptions - to suite different learning styles. Teachers and students can use the Equation panel to evaluate equations, the Data panel to import and plot tabular data and the Simulation panel to model roller coaster physics and rocket launches. MathTrax is fully accessible to screenreader users. These users can conveniently and immediately access MathTrax's alternative text and sound graph descriptions.
