Student

- Text Books – common OCR applications ignore math; publisher PDFs use images
- Study Sheets – similar issues to textbooks; sometimes also handwritten
- Web sites and CMS – math equations on the web typically are images
- Classroom Instruction – how to take accessible math notes?; math verbalization not standard

Instructor

- Tests & Quizzes – special treatment needed for AT to work; students with handwriting issues
- Papers – problem of accessible entry of math equation in word processing applications
- Homework – problem of sighted teachers and blind students being able to use same formats
- Online Activities – how to put accessible math equations on the web; web based math editors?

creation

- Commonly used mainstream WYSIWYG math editor
- Works well as math handwriting accommodation
- Provides for GUI, keyboard or LaTeX math entry
- Exports and imports MathML or LaTeX
- Can be used with DBT or Tiger to create Nemeth braille
- Issue: Not a natively accessible editor with JAWS
- Issue: Equations in Word documents must be exported for use with synthetic speech or braille

- Commonly used mainstream add-on for IE
- Allows web pages or local files containing MathML equations to be displayed in IE
- Acts as a transparent accessibility linkage between IE and assistive technologies
- After installation requires no user intervention
- Works with many AT applications: JAWS, WindowEyes, TextHelp R&W or BA, Serotek

- Requires MS Word, MS Save As DAISY add-in, and MathType.
- Adds "Save As DAISY" to Word's File menu
- Saves document as a DAISY Digital Talking Book with MathML equations

- All braille uses the same 63 symbols
- Context gives meaning
- Seven braille codes

- Each code is slightly different
- Uncontracted braille
- Contracted braille
- Nemeth math braille
- CBC (computer braille code)

- Not all students who read braille read Nemeth math braille
- Be sure to ask!
- Reality check: If the student does not know Nemeth, s/he is unlikely to learn it just to take a math class.

- Numbers
- 1234567890
- #1234567890

- Symbols
- x² + 2x + 2 = 10
- x^2"+2x+2 .k #10

- Use MS Word with MathType
- Or use Scientific Notebook

- Use MathType to create equations
- Use styles in MS Word
- Body text, normal
- Headings 1-3
- List, list bullet, list number
- Index

- Nemeth created with MathType (or Scientific Notebook) may have significant errors
- Have the book done by a Nemeth transcriber
- Try doing handouts in-house
- Check with your student to make sure the braille is acceptable
