Why is Accessibility Important? Up to 20% of people are affected by some form of disability A significant portion of people with disabilities can benefit from web sites specifically designed to be more accessible In the US alone, there are currently estimated 52 million who have cognitive, visual, hearing or physical disabilities which affect their ability to use computers and the Internet
3
What is Web Site Accessibility? Making the web usable by everyone whatever their ability or disability A Web Site is accessible if it can be used as effectively by people with disabilities as by those without A properly designed Web Site should be accessible to all no matter what their disability
4
What types of disability? Visual Impairments Color Perceptions Visual Acuteness Motor/Mobility Impairments Inability to use the hands Tremors Muscle slowness Auditory Impairments Deafness
5
What types of disability? Seizures Photo epileptic seizures Cognitive Impairments Developmental disabilities Learning disabilities Cognitive disabilities
6
So What? Web Accessibility and “So What” What does it mean
7
Assistive Technology Different meanings in different aspects Augmentative Communication Hearing Aids Wheel Chairs Prosthetics
8
Assistive Technology Assistive Technology for access to information Screen Readers JAWS Window Eyes Voice Over Braille Displays Pointing Devices Alternative Keyboards Speech Recognition
9
Equal Access
10
Why is Accessibility Important? Increasing accessibility will: Increase sales Increase audience reach Improve search engine listings Ensure your site complies with disability discrimination law
11
Discrimination? Employment discrimination, lack of access to education materials, reading Paying higher prices (online stores) Lack of access to social communities – accessing twitter/facebook/IM to find out about updates and friends/family. Inability to access information on preparing for emergencies
12
Discrimination – So What? Department of Transportation Regulation Issued in 2008 Allowing that Airlines are NOT required to provide Accessible Websites. HOWEVER… If the Website is NOT Accessible they MUST give you the price of the flight available on the Website at the time of the call. No Call Center Fee charged.
13
Discrimination – So What? UUL Studies identified several Airlines which would not comply with the regulation even when they were informed of the regulation! Would not provide the lower fee (it was 1/3 less) Would not waive the Call Center Fee
14
Discrimination – So What? Similar studies were performed on Employment Discrimination Online Employment Applications 32 Attempted Application Submissions 24 Submitted 9 Without assistance by non disabled users ~ 28% Success Rate
15
Disability Discrimination Law? Over the years many companies have been litigated against and have had rulings made against them 2000 Applicability of the ADA to Private Internet Sites http://commdocs.house.gov/committees/judiciary/hju65010. 000/hju65010_0f.htm

18
Disability Discrimination Law? Target developed their “Online Assistive Technology Guidelines” and was certified by NFB as compliant with these guidelines Target paid NFB $90,000 for the certification and first year of monitoring and then $40,000 per year thereafter Target’s web developers received at least one day of accessibility training Target paid damages of $6,000,000 to the class action claimants Target paid $20,000 to the California Center for the Blind

What does it mean? Guidelines Web Content Accessibility Guidelines World Wide Web Consortium (aka W3C) http://www.w3.org/ http://www.w3.org/WAI/ Accessible Rich Internet Applications (WAI-ARIA) http://www.w3.org/TR/wai-aria/
22
Section 508 Section 508 is a part of the Rehabilitation Act of 1973 relating to accessibility standards applied to Electronic Information Technology (EIT) used by the Federal government Lists 16 separate items which must be met to be in compliance http://www.section508.gov/ http://www.webaim.org/standards/508/checklist
23
508 Checklist (Cont.) Text equivalents for non-text elements Equivalent alternatives for any multimedia presentation Don't rely only on color to indicate differences Must be usable without stylesheets Client-side and server-side image maps Identify row and column headers for data tables
24
508 Checklist (Cont.) Title frames to facilitate identification and navigation Avoid screen changes on pages between 2Hz and 55 Hz Use text only pages when necessary Provide text notification when using scripting languages Provide a link to any applet/plug-in/application required
25
508 Checklist (Cont.) Design forms which can be used by assistive technology Skip repetitive navigation links Provide alternatives for timed responses
26
508 Checklist (Script) Allow for keyboard only usage Do not disrupt/disable accessibility features Clearly identify the current on screen focus Provide information about UI elements to AT (Assistive Technology)
27
508 Checklist (Cont.) Consistency for use of images as controls Do not override user selected contrast and color selections Allow for non animated versions of animated objects No flashing/blinking text

Web Content Accessibility Principles Perceivable Operable Understandable Robust Guidelines Success Criteria Sufficient and Advisory Techniques
30
Perceivable Information and user interface components must be presentable to users in ways they can perceive. Guideline - Text Alternatives: Provide text alternatives for any non-text content so that it can be changed into other forms people need, such as large print, braille, speech, symbols or simpler language. Technique –
31
Operable User interface components and navigation must be operable. Guideline - Keyboard Accessible: Make all functionality available from a keyboard Technique – S ave
32
Understandable Information and the operation of user interface must be understandable. Guideline - Readable: Make text content readable and understandable. Technique – <acronym title="North Atlantic Treaty Organization"> NATO CSS
33
Robust Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. Guideline - Compatible: Maximize compatibility with current and future user agents, including assistive technologies (Semantic Web Site) Technique – My Page Heading
34
Real World Accessibility In the last 10 years, on average, 10%-20% of Federal Websites examined are in compliance with Section 508 Universal Usability Laboratory – Evaluated 100 Federal Homepages
35
Real World Accessibility Out of 100 Federal Homepages Human Inspection 96% Violated Section 508 Automated Tools Inspection 92% Violated Section 508
36
Real World Accessibility Of the 100 Federal web sites examined 58% - Have an accessibility statement 42% - Say they are “508 compliant” 22% - Statement describing accessibility features 3% - Statement describing tools used to test for accessibility 2% - Describe process used to develop or ensure accessibility compliance 2% - Describe how often the site is checked for compliance

Making a Web Site Accessible Building Web Sites Using Web Standards http://msdn.microsoft.com/en-us/library/aa479043.aspx Accessibility Support in ASP.NET http://msdn.microsoft.com/en- us/library/ms228004(VS.80).aspx http://msdn.microsoft.com/en- us/library/ms228004(VS.80).aspx Creating an Accessible Web App http://msdn.microsoft.com/en- us/library/3has1x30(VS.80).aspx http://msdn.microsoft.com/en- us/library/3has1x30(VS.80).aspx

Making a Web Site Accessible Check Accessibility of Web Pages (using Visual Web Developer) http://msdn.microsoft.com/en- us/library/ms247244(VS.80).aspx http://msdn.microsoft.com/en- us/library/ms247244(VS.80).aspx ASP.NET Controls and Accessibility http://msdn.microsoft.com/en- us/library/ms227996(VS.80).aspx http://msdn.microsoft.com/en- us/library/ms227996(VS.80).aspx
48
Good Reading Web Accessibility In Mind http://www.webaim.org http://www.webaim.org/articles Accessibility Myths http://htmlhelp.com/design/accessibility/myths.html http://www.techsoup.org/learningcenter/access/archives/pa ge9994.cfm http://www.webcredible.co.uk/user-friendly-resources/web- accessibility/myths.shtml http://www.csszengarden.com/
49
Compliance Testing Just because a site passes accessibility checks does NOT mean the page is useable The only true test is the user test Having an individual whose primary vehicle for accessing the internet and websites with their screen reader is the best and most accurate test available Usability is the goal and usability by the user is the ultimate test
50
Accessibility is NOT Expensive Hire a proper front end developer Start from Scratch Clean Compliant Code Ease of Maintenance Better for SEO Avoid Legal Issues
