3. 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
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.
Copyright by InftyReader Group, Inc. All rights reserved.

5. 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.
Copyright by InftyReader Group, Inc. All rights reserved.

6. 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
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.

14. InftyReader: Target Documents
Printed books
Images of equations
PDF files that include image-based math expressions (not text-based expressions).
Copyright by InftyReader Group, Inc. All rights reserved.

15. Example: Text-Based Math Expression
If you can select individual symbols with your mouse, you are looking at a text-based math expression.
Copyright by InftyReader Group, Inc. All rights reserved.

16. Text-Based Math Expression
Extracted, text-based, math expressions are useless when it comes to rendering math content into accessible formats. For example, here’s what the text extraction of the math expression on the previous slide looks like:
Y0 (t) = nX-1 j=1 Xj (y(t))dyj dt (t)

17. Example: Image-Based Math Expression
If you cannot select individual symbols with your mouse, you are looking at an image-based math expression.

18. Example: Simple Layout Document
Automatic conversion of simple layout documents is easy with InftyReader. For example:

19. Example: Complex Layout Document.
Automatic conversion of complex layout documents is not easy and normally requires a combination of automatic and manual actions. For example:
