InftyReader is an Optical Character Recognition (OCR) application that automatically converts "inaccessible" math content such as: 1) printed textbooks containing mathematics; 2) images containing mathematics; and, 3) PDF files that containing mathematics into formats that are accessible by students with "print disabilities." These formats include LaTeX, MathML, and Word XML. A "print disability" is a condition related to blindness, visual impairment, specific learning disability or other physical condition in which the student needs an alternative or specialized format (i.e., Braille, Large Print, Audio, Digital text) in order to access and acquire knowledge from conventional print/digital materials. ChattyInfty 3 is a talking math editor. It can be used to edit files processed by InftyReader. Once editing is complete, ChattyInfty 3 can export files into a wide range of accessible formats including: 1. Spoken Text 2. DAISY 2.02 multimedia 3. DAISY 2.02 audio 4. DAISY 3 multimedia 5. DAISY 3 text (with audio for math) 6. DAISY 3 text-only 7. EPUB3 media overlays 8. EPUB3 no audio 9. EPUB3 iBooks media overlays

2. 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
2

3. 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.
3

4. 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.
4

5. 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.
5

6. Example: Alt-Text
“StartFraction StartRoot 2 x plus 3 EndRoot Over
x minus 4 EndFraction”
6

7. Solution
Use LaTeX, MathML, and Word XML to
render math content into formats that are
accessible by students with print disabilities.
7

8. 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.

13. InftyReader: Target Documents
• Printed books
• Images of equations
• PDF files that include image-based math
expressions (not text-based expressions).
13

14. Example: Text-Based Math Expression
If you can select individual symbols with your
mouse, you are looking at a text-based math
expression.
14

15. 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)
15

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

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

18. 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:
