What is Accessibility?
“Universal Design” Designing for the largest audience
possible regardless of disability or ability
– UMN Duluth Web Glossary
“Universal Access”
“…regardless of disability, location, device or speed of connection to the Internet [or audio]”
Example Needs•Visually impaired On a screen reader
•Hearing Impaired Captions/transcripts needed
•Low Vision Legibility crucial, may zoon to 200%
•Motion Impaired (hands) Keyboard access critical
Stakeholders•Users with disabilities Multiple needs for visual, hearing,
motion, cognitive disabilities
•Web Developers Training & tools needed Some chamomille tea as well?
•Instructors How do we handle immense volume
online materials from “non-professionals”?
Case: Severe Visual Impairment
•Requires a screen reader to read Web content aloud Multimedia, images need to be
describedNot all descriptions need to be hidden
Program elements need to identify themselves
•Hidden Audience Text-based mobile device, missing
plugin, images disabled, or broken image link
What the “ALT Tag” does
Piston diagram images
Text describes piston position
ALT Tagger in ANGEL CMS
Enter information “Alternative Text” field when uploading images
New Apps Gotcha
•Not all apps and plugins include information for screen reader Old iTunes: MP3 music files were
accessbile, but navigation in iTunes was not
Some users encounter difficulty creating a login! (esp Flash based interface)
Web Forms – Need to signal new informationSee WAI-ARIA for how to code. JavaScript CAN be accessible.
Case: Hearing Impaired•You cannot hear content Captions, captions, captions (or
transcript)
Some users more fluent in sign language
•Hidden Users Forgot headphone in lab
Audio cuts out
Can’t find one of 5 volume controls
Poor audio quality (even for normal hearing)
50% students used captions in online class
Captions Reveal Information
Caption shows how to spell Cole Camplese’s name.

Issues:
•Can we simplify training without losing functionality?
•Can accessibility be included in curriculum for tech professionals?
•Who will listen?•“Professionals” yes, but others?
