3
Section 508 A Brief History
  • Convergence of factors
  • Disability Rights Movement
  • Barrier-free Design to Universal Design
    Movement
  • Advances in Rehabilitation Engineering
    Assistive Technologies

4
Section 508
  • Increasing population of individuals with
    special needs
  • Adults now live an average of 30 years longer
    than did adults at the beginning of the 20th
    century which means many are faced with
    diminishing
  • Vision
  • Hearing
  • Mobility Agility
  • Improved medical care means that more people
    survive once fatal accidents and illnesses

5
Section 508
Five Types of Disabilities to ConsiderWhen
Designing Websites
  • Visual Impairment
  • Hearing Impairment
  • Mobility Impairment
  • Cognitive Impairments
  • Seizure Disorders

6
Some Website Design Implications
  • Text equivalent for non-text elements
  • Equivalent alternatives for multimedia
    presentations must be synchronized
  • All information conveyed with color will also be
    available without color
  • Redundant links shall be provided for each
    active region of a server-side image map
  • Provide method that permits user to skip
    repetitive navigation links
  • Design pages to avoid causing the screen to
    flicker with a frequency greater than 2Hz and
    lower than 55 Hz

7
Why should I be concerned whether my website is
accessible?
  • Turn off images
  • Turn off sound
  • Unplug the mouse

8
Where to start
http//www.w3c.org/WAI/
9
Where to start
  • Images provide ALT tags to provide descriptors
    for all images
  • Image maps use client-side Map and text for
    hotspots
  • Multi-media provide captioning and transcripts
    of audio and descriptions of video
  • Hypertext links use text that makes sense when
    read out of context.
  • Page organization use headings, lists, and
    consistent organizing structure
  • Graphs charts summarize or use the longdesc
    attribute
  • Scripts, applets, plug-ins provide alternate
    content
  • Frames label frames
  • Tables make line by line reading sensible
  • Check your work validate HTML

Overview
  • Several types of multimedia exist today
  • New forms being created, things change fast
  • Key concepts
  • Caption sounds and images into text for reader
    software
  • Allow keyboard navigation
  • Todays agenda from older and better
    standardized to newer and less understood

21
Multimedia Is Wonderful, but...
  • Avoid eye candy if it excludes parts of your
    audience
  • Remember bandwidth limits
  • Dial-in users may find multimedia too big
  • To be accessible, transcription will be needed
  • Text can be utilized for reading, text-to-speech,
    and Braille

22
Principles of Captioning for Multimedia
  • Synchronized - the text content should appear at
    approximately the same time that audio would be
    available
  • Equivalent - content provided in captions should
    be equivalent to that of the spoken word
  • Accessible - caption content should be readily
    accessible and available to those who need it

Standards 508(b) W3C Guidelines
23
Audio/Video Captioning Options
  • Text captions, synchronized with the images
  • Text transcript file
  • Best for text-only devices, Braille printers
  • Audio description track for video
  • Alternative language text/audio tracks

24
Internet Video Captions
Words appear below the image, when enabled in the
viewer
25
Audio/Video Examples
  • Familiar logo in audio
  • http//www.webaim.org/training2002/week4/captions/
    audioDesc.mp3
  • Manhole video with audio and text
  • http//main.wgbh.org/wgbh/movies/manhole.mov
  • Pure transcript also available

26
Audio/Video Current Tools
  • MAGpie -- A free tool from NCAM for creating
    captions and audio descriptions. Creates captions
    compatible with RealPlayer, QuickTime, and
    Windows Media Player.
  • SMIL -- Synchronized Multimedia Integration
    Language -- is a general method of marking up
    content for many formats

27
Key Resources and Services
  • EASI Online unit on creating accessible
    Internet multimedia
  • http//easi.cc/workshop.htm
  • NCAM (especially for video captioning)

28
Presentation Media
  • PowerPoint
  • Poor accessibility in PowerPoint itself
  • Office 2K/XP generated HTML has outline, but
    lacks tags for images, tables, text boxes
  • New tool helps guide you to fill the gaps
  • http//www.rehab.uiuc.edu/ppt/index.html
  • Acrobat PDF
  • Future version will be accessible
  • For now, produce an alternative in HTML and make
    it accessible
  • http//www.webaim.org/articles/pdfandppt

29
Animation/Simulation
  • Java
  • SMIL support added recently (Soja, Schmunzel)
  • Few older applications are accessible
  • Flash
  • New versions are designed for accessibility
  • Guidelines for design on Macromedia site
  • http//www.macromedia.com/macromedia/accessibility
    /features/flash/

30
Synchronous Events
  • Text chats are easy, in principle
  • Beware non-accessible java applets
  • Voice presentations can be captioned in advance
  • Voice chats require live transcription, the most
    cost-intensive element
  • Example EASI Chatterbox
  • http//easi.cc/cbox.htm

31
Example Chatterbox
Voice chat, text chat, and presentation at the
same time
32
Universal Design
  • Many advantages when media has multiple
    representations
  • Different learners use different aspects
  • Quiet areas can be used
  • Other languages can be added
  • Navigating within a video is easier by searching
    captions
  • General search tools like Google can find a
    transcript, and lead users to the media
