Overview
  • Introduction
  • What is accessibility?
  • Background
  • Accessibility examples
  • Resources
  • Questions Answers

3
Self Assessment
  • Please take a few moments

4
Imagine
  • Being hearing impaired
  • And watching a video clip on the internet
  • Without captions

5
Imagine
  • Being visually impaired
  • And navigating a website

Only through sound
6
  • Are most websites designed to be spoken?

7
Imagine
  • Being physically challenged
  • And not using a mouse -

Can most websites be navigated without one?
8
Reality, 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

9
W3C 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
10
What Is Accessibility?
  • Everyone can use the site or services
  • Peoples differences do not matter
  • Happens by design and implementation

11
Reasons for Accessibility
12
The 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

13
Americans 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)

14
Section 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

15
Section 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

16
Why 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

17
To 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?

18
Section 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.

19
The 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

20
Other Considerations
21
Considerations
  • 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

22
Considerations
  • Accessible design is good design
  • Faster pages
  • Easier to navigate
  • Wider audience (e.g., cell phones, browser
    differences, graphics turned off, slow modem
    connections)

23
Considerations 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

24
Web Accessibility Issues
  • Graphical User Interface main issue
  • Visual
  • Using the mouse
  • Affects mostly those with visual disabilities

Web 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?

27
Simulations
  • Low Vision

28
Different 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

29
Web 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

30
Six 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?

31
How 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

32
Present 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

33
Access 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

34
Alt 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

35
Relative 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

36
Use 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

37
Use 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

38
Cascading 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

39
Accessibility 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

40
Too 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

41
Software and Accessibility
  • Microsoft Word
  • http//webaim.org/techniques/word/
  • Microsoft Frontpage
  • http//webaim.org/techniques/frontpage/
  • Microsoft PowerPoint
  • http//webaim.org/techniques/powerpoint/
  • Flash
  • http//webaim.org/techniques/flash/
  • Adobe PDF
  • http//webaim.org/techniques/acrobat/
  • Overall
  • http//webaim.org/techniques/

42
Accessibility 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

43

  • Lynx Text Browser
  • http//www.delorie.com/web/lynxview.html
  • Vischeck for color issues
  • http//www.vischeck.com/vischeck/vischeckURL.php

44
Building 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
