Instructional PathwaysCommon Problems for Math
  • 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

Assessment PathwaysCommon Problems for Math
  • 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?

  • InftyReader
    • Math OCR software
    • Data conversion
  • InftyEditor
    • Editor of math documents
  • ChattyInfty
    • InftyEditor + speech output
    • Authoring and editing tool of math documents for visually impaired users
www dessci com mathtype mathtype
www.dessci.com/mathtype MathType
  • 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

www.dessci.com/mathplayer MathPlayer
  • 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
braille
Braille
  • 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)
bottom line
Bottom Line
  • 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.
nemeth braille example
Nemeth Braille Example
  • Numbers
    • 1234567890
    • #1234567890
  • Symbols
    • x² + 2x + 2 = 10
    • x^2"+2x+2 .k #10
creating math braille
Creating Math Braille
  • 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
reality check
Reality Check
  • 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
