Susan M. Johns Smith
  • Axe Library
  • Pittsburg State University
  • Pittsburg, Kansas
3
Approaches and Tools
  • W3C Validator, http://validator.w3.org
    • Recommended for HTML 4.0, XHTML 1.0, CSS Level 2, XML 1.0
    • Quality, structure, consistency and reliability of the code
4
Approaches and Tools
  • Zoomtext, http://www.aisquared.com
    • Magnification and screen reading
    • Primarily for low-vision users
    • Magnification up to 16X
    • Useful for font, line spacing, and graphic integrity
5
Approaches and Tools
  • Bobby, http://bobby.watchfire.com
    • Simple to understand language
    • Three levels of accessibility defined
    • Interpretive Nature lends itself to criticisms

6
Approaches and Tools
  • “If Bobby is the only test… it is possible to produce a site with accessibility problems… it might be more accurate to say that Bobby can…identify inaccessibility than to verify accessibility…”--Quinn (2001)
7
Approaches and Tools
  • Vischeck Color Simulator, http://www.vischeck.com
    • Simulates Deuteranope, Protanope, and Tritanope color vision
    • Most useful to determine effective use of contrast


8
Approaches and Tools
  • JAWS for Windows, http://www.freedomscientific.com/
    • Braille interface
    • Screen reader with various  “modes” and shortcuts
    • Useful for motor skill navigation of links, pull down (combo) and input boxes


9
Approaches and Tools
  • Browser Testing
    • Amaya, http://www.w3.org/Amaya/
    • Opera, http://www.opera.com
    • Lynx, http://lynx.browser.org
    • Netscape and Internet Explorer
10

Accessibility Summary
49
Summary –
Validation and Tools
  • Insist on standards for coding html/xhtml
  • Insist on browser independence
  • Employ accessibility tools vigorously to all pages
50
Summary –
Magnification
  • Avoid use of any italics or thin fonts that disintegrate
  • Watch quality of graphics
  • Watch yellow or pastel fonted words
  • Watch link colors
51
Summary –
Color Impairment
  • Pay attention to contrast
  • Modify colors to match logos or school colors?
  • Watch quality of gifs, jpgs, logos, buttons
52
Summary –
Screen Readers
  • Test multiple readers
  • They are all not the same
  • They can read differently
  • They have different features, i.e., skip links
53
Summary –
Screen Readers
  • They have different shortcuts and functionality
  • They have different commands to navigate within the reader proper
54
Summary –
Screen Readers
  • Test readers your users use
  • Do not force disabled to learn a new reader in order to use the library catalog
55
Summary –
Screen Readers
  • What’s healthy for the visually impaired is also useful for the palm pilots
  • A good, clean design will withstand numerous iterations for all products
56
Summary –
Motor Skill Navigation
  • <Tab> through the page
  • <BackTab> through the page
57
Summary –
Motor Skill Navigation

  • Check all pull-down boxes for ability to read and display using <arrows> to ensure all options are visible
58
Summary –
Motor Skill Navigation

  • Check all <submit>, <go>, <send> buttons for ability to activate the desired action, form, or search
59
Summary –
Motor Skill Navigation
  • How do you get from the top to the bottom?
  • How do you get from the bottom to the top?
60
Summary –
Motor Skill Navigation
  • Can you skip over
  •   re-occurring material?
  • Can you fully access the page without a mouse?
61
Summary -
Additional Testing Procedures
  • Keep the design clean from release to release; test after each new update
  • Test vigorously in-house before live testing with disabled users
62
Summary –
Additional Testing Procedures
  • Test vigorously with disabled users and be ready to make changes and adjustments, not mere lip service
63
Summary –
Additional Testing Procedures
  • Try to separate accessibility from usability
  • Definition:
64
Summary –
Additional Testing Procedures
  • Usability is analyzing how long it takes you to find a piece of information – how many clicks, where on the page, etc.
65
Summary –
Additional Testing Procedures
  • Accessibility is knowing that information exists, but trying to get at it with your eyes closed and a stick in your mouth


66
Never, ever apologize for advocating for a more useful, more universal design, on behalf of others.
