A few technology conditions that make using computers a bit difficult or impossible

mismatched OS, no internet connection, browser implements html in peculiar way, noisy phone line, limited colors, limited font set, lack of electricity, too complicated to learn

reaching across technological divides
Reaching across technological divides
  • Problem: user began using Mac OS in 1985 and doesn’t want to change
  • A possible solution: customizable UI
reaching across technological divides1
Reaching across technological divides
  • Problem: website needs to serve users with old, poorly-supported computers
  • A possible solution: use “standard” design
    • HTML-only
    • 256 colors
    • Font: arial or times
    • Maybe text-only!
reaching across technological divides2
Reaching across technological divides
  • Problem: need to browse the internet but unreliable electricity, erratic and noisy phone lines, no internet
  • A possible solution: paper user interface
    • FAX server sends web page
    • Circle underlined item
    • FAX back
    • Receive linked page

Complying with ADA

What is the Americans with Disabilities Act?

Reasonable accommodation is any modification or adjustment to a job or the work environment that will enable a qualified applicant or employee with a disability to participate in the application process or to perform essential job functions. Reasonable accommodation also includes adjustments to assure that a qualified individual with a disability has rights and privileges in employment equal to those of employees without disabilities.

assistive technologies1
Assistive Technologies
  • A sample list (from the Mishawaka, IN public library):
    • ZoomText
    • JAWS for Windows
    • Kurzweil 1000
    • Kurzweil 3000
    • Hands Off
    • Dragon Naturally Speaking

  • Problem: learning disability
  • A possible solution: early childhood toys

Assistive Technologies
  • Problem: user can only manage special buttons
  • A possible solution: xkeys
    • On/off to USB connector
assistive technologies8
Assistive Technologies
  • Problem: unable to use hands
  • A possible solution: head mouse
assistive technologies9
Assistive Technologies
  • Problem: people with alzhiemers often forget routine tasks
  • A possible solution: a memory mirror
    • “reflects” if person fed the cat and the goldfish
    • Georgia Tech project
    • RF tagged pet food
    • Also set to alert family/friends

Assistive Technologies
  • Problem: deaf and blind student
  • A possible solution: C-Print/JAWS/BrailleNote
    • “Captionist” types a written transcript of what is said in class
    • Displayed in Braille on a Braille laptop called the BrailleNote.
    • When used with C-Print captioning, information is 'fed' into Jaws (a screen-reading software) and sent to the Braille Note, rather than being spoken. 
    • User can fully participate in class: unfamiliar names or vocabulary are accessible; can follow a class or group discussion more easily since who is speaking and when is known.
