Credits and Thanks This presentation is an adaptation of “Technology to make Scientific Documents Accessible,” originally created by Masakazu Suzuki, Professor emeritus (Kyushu University) and Katsuhito Yamaguchi (Nihon University) in November, 2014 What are STEM Documents? Science, Technology, Engineering, and Math (STEM) documents may include any/all of the following: • Text • Math/chemical formulas • Tables • Diagrams • Flow charts • Figures and graphs Societal Barriers to Math Accessibility Some people believe: • Providing students with print disabilities access to math content is too difficult and time- consuming; • Most students with print disabilities find math too complex; and, • Because of these reasons, making math content accessible is not worth the time and effort.

1 Accessibility Issues: Math Images Often, images of mathematical equations appearing on web pages and in eBooks/PDF documents: • Are not accessible by students using AT; • Do not provide for alternative output modalities, such as Braille or synthetic speech; • Cannot be altered, easily, to accommodate the learning needs of students with low vision (color and contrast changes); and, • Require authors to redraw images when even small changes are made. Accessibility Issues: Alt-Text Tags • Are limited to a narrative description of math equations; • Must be hand-coded by someone who fully understands the context of the expression; • Do not provide ways to intelligently navigate though math equations in order to understand them; • Do not eliminate the previously mentioned issues like support for Braille math output; • Must contain unambiguously, consistent, descriptions of the math.; and, • Only provide a limited form of accessibility, and only for the simplest equations. Solution to Math Accessibility Problems Use LaTeX, MathML, and Word XML to render math content into formats that are accessible by students with print disabilities. What is InftyReader? InftyReader is an Optical Character Recognition (OCR) application that recognizes image- based STEM content automatically, and can then convert it into LaTeX, MathML, and/or Word XML. InftyReader Minimum Requirements • No Pixelation, 600DPI, B&W (Binary) Only • No Pixelation, 600DPI, B&W (Binary) Only Document Characteristics that do not Meet the Minimum Requirements • Pixelated, Grayscale Characters • Background Colors • Pixelated and/or Grayscale Characters • Dirty Background or Off-Horizontal • Characters Running Together • Broken Characters
