- Resources
- Questions Answers
3Self Assessment
- Please take a few moments
4Imagine
- Being hearing impaired
- And watching a video clip on the internet
5Imagine
- Being visually impaired
- And navigating a website
Only through sound
6- Are most websites designed to be spoken?
7Imagine
- Being physically challenged
- And not using a mouse -
Can most websites be navigated without one?
8Reality, Not Imagination
- Such are the realities for over 200,000 special
needs students in New Jersey - They can access their schools but not the school
information posted on the web - They can navigate a textbook but not the
classroom homepage - They face internet barriers rarely considered
9W3C Web Accessibility Initiative (WAI)
- "The power of the Web is in its universality.
Access by everyone regardless of disability is an
essential aspect." - -- Tim Berners-Lee, W3C Director and inventor
of the World Wide Web
W3C World Wide Web Consortium
10What Is Accessibility?
- Everyone can use the site or services
- Peoples differences do not matter
- Happens by design and implementation
11Reasons for Accessibility
12The Law
- The Americans with Disabilities Act (ADA), and
Sections 504 as well as 508 of the Rehabilitation
Act, prohibit discrimination against people with
disabilities in all aspects of daily life - This includes education and work
13Americans with Disabilities Act (ADA)
- no qualified individual with a disability shall,
by reason of such disability, be excluded from
participation in or be denied the benefits of the
services, programs, or activities of a public
entity (Title II, ADA, 1990)
14Section 504 of the Rehabilitation Act of 1973
- Organizations that receive money from the federal
government are prohibited from discriminating on
the basis of disability - Public schools receive federal monies
15Section 508 of the Rehabilitation Act of 1973
- All federal electronic information technology
(IT) goods and services that are purchased must
comply with specific and established
accessibility standards (29 U.S.C. 794d) - By doing this, the federal government is creating
industry standards for accessibility - So although other organizations, such as states,
are not mandated to use 508 standards for all
technology purchases states are beginning to do
so by passing their own 508 standards
16Why Section 508
- To remove barriers in information technology
- To make new opportunities available for people
with disabilities - To encourage the development technologies that
focus in achieving these goals
17To Whom Does 508 Apply
- All federal agencies as they develop, procure,
and maintain or use electronic and informational
technology - Other agencies that receive federal monies
- You?
18Section 508 and New Jersey
- New Jersey Accessibility statement
- http//www.state.nj.us/accessibility.htm
- New Jersey state agencies subject to this policy
shall take reasonable steps to design and develop
Web sites and Web services so that they are
accessible to people with disabilities as well as
those without disabilities.
19The Individuals with Disabilities Education Act
of 1997 (IDEA)
- Requires that schools provide students with
disabilities an equivalent, appropriate education - Not providing information on a school/classroom
website in an accessible format may be a legal
concern if the information is necessary for
coursework, homework, library services,
distance-learning
20Other Considerations
21Considerations
- Districts/Schools/Classrooms should design
accessible web sites for reasons other than just
The Law - A website is an organizations best face to the
world - Students
- Parents
- Grandparents
- The community
- Roughly 10 percent of the population, possibly up
to 20 percent who surf the net are disabled
22Considerations
- Accessible design is good design
- Faster pages
- Easier to navigate
- Wider audience (e.g., cell phones, browser
differences, graphics turned off, slow modem
connections)
23Considerations in New Jersey
- Since 1997, Educational Technology Unit has
required web sites as an outcome for all its
grant programs - As of November 2004, web sites will be required
to be accessible for its grant programs
24Web Accessibility Issues
- Graphical User Interface main issue
- Visual
- Using the mouse
- Affects mostly those with visual disabilities

26Web Accessibility Issues
- Other issues
- Movement (epilepsy)
- Colors (vision contrast)
- Sounds (captions)
- Organization and complexity on page (cognitive)
- Keep structure of a page the same throughout the
site - Is the site too busy?
27Simulations

28Different Ways to Surf
- Screen readers
- JAWS (Freedom Scientific)
- outSPOKEN (ALVA)
- Window-Eyes (GW Micro)
- HAL (Dolphin Computer Access)
- Talking browsers
- Home Page Reader (IBM)
- WeMedia Browser (WeMedia)
- Screen magnifiers
- Pointers (e.g., head wand, trackball)
- Refreshable Braille readers
- Keyboard only
29Web Accessibility PrioritiesAllowing for
differences
- Priority 1 (A)
- The must haves
- Basic requirements
- Priority 2 (AA)
- The should haves
- Removes significant barriers
- Priority 3 (AAA)
- The may have
- Design considerations
- W3C Checkpoints
30Six Guiding Questions
- Can the site be navigated using only a keyboard?
- Does the site override personal OS settings?
- Accessibility features
- Color and contrast settings
- Are there flashing or blinking images?
- Is color the sole means of conveying information?
- Is there an alternative format for information
conveyed with images, icons, or animation? - Is the site compatible with a screen reader?
31How to be accessible
- Present main content first
- Access key navigation
- Alt text
- Relative font sizes
- Use color safely
- Use real text, not graphics of text
- Cascading Style Sheets (CSS)
- Accessibility Statement
32Present Main Content First
- Viewers can access main information without
having to scroll or hear navigation links first
on every page - Having to wade through links as the first element
in every page can be burdensome
33Access key navigation
- Allows for keyboard short cuts to be used to
navigate to links - lta hrefwww.njdoe.htm accesskey"1"gtHome
pagelt/agt - User presses ALT 1 to go to link
34Alt text
- Alt text
- Describes images on a web page
- Allows visually impaired to sense what the
graphic contains - ltimg src"house.jpg" height"110" width"320"
alt"The house is white, with green shutters on
the windows. "/gt - Do not just list the name of file
- ltimg src"house.jpg" height"110" width"320"
alt" house.jpg "/gt
35Relative Font Sizes
- Do not assign fixed or absolute sizes
- font-size 12px
- Use relative or percentages
- font-size small
- This allows for users to manipulate and set
larger fonts for themselves
36Use Color Safely
- Have enough contrast so that the background and
text are discernable - Do not just use color to convey important
information - A word/link only highlighted in red may not be
perceived by a person with color/vision
challenges - Use bold, italics, or underline in conjunction
with color
37Use Real Text
- Making a graphic button with text on it is not as
visible as real text - Real text is easier for screen readers
- Real text can be enlarged and remain clear
graphics blur
38Cascading Style Sheets
- Separates form from content
- All of the formatting is done by the style sheet
and the web page has only content - Allows for quicker loading of page (less for
browser to process) - Allows for easy way to change styles on all pages
39Accessibility Statement
- Include an accessibility statement on web site
- List the accessibility features that are present
on the site - Make it informative but also educative so
others visiting your site may be inspired to do
the same
40Too Hard Im Using Only Text
- We understand your pain
- Take everything one step at a time
- Plain text web sites are not very engaging!
- These techniques are not burdensome once they are
learned - Building a new site with these considerations is
easier than retrofitting an established site - So if redoing a site do it a little at a time
41Software and Accessibility
- Microsoft Word

42Accessibility Checkers
- To identify potential accessibility problems on
Web pages - Some automatic checks
- Human interpretation always needed still a time
commitment - Some Web-based and programs run from your hard
drive
43Accessibility Checkers

- Lynx Text Browser

- Vischeck for color issues
- http//www.vischeck.com/vischeck/vischeckURL.php
44Building the Process
- Policy is needed to address accessibility issues
as part of the overall redesign effort of web
site - Policy must include
- Checking for accessibility must become part of
the usual web development process - A way to ensure that accessibility is being
incorporated - And more
