NYS Policy Requirements
• New content must conform immediately
• Any content developed by contractor must
conform
• Provides language to include in any
procurement involving web content
• Policy requires annual validation and reporting
to CIO/OFT
How People With Disabilities Use
the Web
Blindness / Low Vision
• People who are blind access the web via:
– Screen reading software
– Refreshable Braille displays
– CANNOT use pointing devices
• People with low vision may use those tools or:
– Screen magnification software
– External (larger) displays
Blindness / Low Vision
• Visual acuity also a factor for:
– People using mobile devices
– People using older equipment (smaller monitors,
lower resolutions)
• Visuals need to be described using “alt text”
• Videos or presentations containing instruction
needs to be audibly described
Low Vision
• Cataracts
• Glaucoma
Low Vision
• Macular Degeneration
• Retinopathy
Magnified graphical text
• Difficult to magnify graphical text without
distortion
Color Blindness
Map of Hurricane Isabel (with color)
Color Blindness
• Map of Hurricane Isabel (simulating red/green color
blindness)
Color Blindness
• Subway maps
Deafness / Hearing Impairment
• Video or presentation content with audio
must be captioned
• Elearning content cannot rely on audio cues
• People whose computers do not support
sound
• Can be an issue for mobile device users
Mobility Impairments
• Cannot use mouse for navigation
• Interaction through keyboard only
• May have difficulty with timed responses
Cognitive Impairments
• Images are helpful for many with cognitive
impairments
• Avoid “Wall o’ Text”
• Use headlines and bullets
• Attention to “fog index”
Principles of Accessibility
• Users may require assistive technology to
effectively use technology or browse web
• Provide information in more than one format
• Navigation and layout should be consistent,
predictable
• Alternate text should describe visual content’s
purpose [not necessarily a literal description
of the content]
Testing for Accessibility
• Three basic ways to evaluate
– Automated testing
– Manual review
– Functional testing
Automated Testing
• Automated testing tools don’t usually fix
errors
• The best tools link error reports to the
standard being violated
• Web developers will need a fairly
comprehensive understanding of HTML and
CSS
Automated Testing
• Many free, but limited [e.g., can only test a
page at a time]
• Many for-fee tools customizable and can do
batch testing
• Most can select either of the two major
accessibility standards (Section 508 or WCAG)
• Automated testing not all that’s needed
Manual Evaluation
•
•
•
•
•
•
•
Look at alternate text for images
Turn off images and styles
Turn off scripting
Use keyboard to navigate
Data table markup
Look at use of color
Proprietary formats
Functional Testing
• Have a user of assistive technology test site
while you watch
• Test with “one of each”
•
•
•
•
User with visual impairments
User with hearing impairments (if sound on site)
User with cognitive impairments
Etc.
The Short-Term Future –
Web Standards
• HTML & CSS Changing
– HTML5 – some backward compatibility, but would
deprecate some accessibility features available in
HTML 4
– CSS3 – little impact on accessibility
– ARIA – Might be used to mitigate some of the
accessibility problems currently existing in HTML5
The Short-Term Future –
Accessibility Standards
• WCAG 2.0
– Now a recommendation
– Support and implementation materials available
on the W3C site, WebAIM, etc.
The Short-Term Future – U. S. Law
• Section 508 about to undergo “refresh” –
move to harmonize with WCAG 2.0
• ADA is being modified to cover the web, both
public sector sites and private sector sites that
function as “places of public accommodation”
• ADA changes also suggest harmonization with
WCAG 2.0
The Short-Term Future – NYS Law
• Assembly bill in the last session required NYS
to comply with Section 508 in toto
• Working with sponsor to include supports
• Outcome will depend upon election
