CVAA
Communications and Video Accessibility Act of 2010“Two decades ago, Americans with disabilities couldn’t get
around if buildings weren’t wheelchair accessible; today
it’s about being Web accessible. The ADA mandated
physical ramps into buildings. Today, individuals with
disabilities need online ramps to the Internet so they
can get to the Web from wherever they happen to be.” – Rep.
Ed Markey (D-MA)
W3C
Web Content Accessibility Guidelines (WCAG) 2.0“…make content accessible to a wider range of
people with disabilities, including blindness and low
vision, deafness and hearing loss, learning disabilities,
cognitive limitations, limited movement, speech
disabilities, photo-sensitivity and combinations of these.”
– Abstract from WCAG 2.0, 11 Dec 2008
