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

• 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

Blindness / Low Vision

• Cataracts

• Glaucoma

Low Vision

• Macular Degeneration

• Retinopathy

Low Vision

• Difficult to magnify graphical text without distortion

Magnified graphical text

Color Blindness

Map of Hurricane Isabel (with color)

• Map of Hurricane Isabel (simulating red/green color blindness)

Color Blindness

• Subway maps

Color Blindness

• 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

Deafness / Hearing Impairment

• Cannot use mouse for navigation• Interaction through keyboard only• May have difficulty with timed responses

Mobility Impairments

• Images are helpful for many with cognitive impairments

• Avoid “Wall o’ Text”• Use headlines and bullets• Attention to “fog index”

Cognitive Impairments

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
