Maximum Accessibility: Making Your Web Site More Usable for Everyone

Table of Contents


This appendix presents linearized versions of four tables included in the main text.

Table C-1 provides the name of the museum, its URL, and some brief, noncomprehensive comments about the barriers we encountered on each site. All sites were accessed on June 8, 2002, except for the Smithsonian site, accessed February 16, 2002.

Table C-1. Accessibility Barriers on Selected Museum Web Sites

Museum: Chicago Museum of Science & Industry

URL: http://www.msichicago.org

Comments: Graphical links have no meaningful information, for example, "link graphic button." Text links have redundant titles, making them difficult to sort and therefore to use by users with screen readers.

Museum: Houston Museum of Natural Science URL: http://www.hmns.org/ Comments: No alternatives are provided for graphic information including important navigation links.

Museum: Musée du Louvre

URL: http://www.louvre.fr/

Comments: Frames names provide no orientation information. Graphic image links appear without meaningful ALT texts.

Museum: Museum of Fine Arts Boston

URL: http://www.mfa.org/

Comments: Splash screen with untagged image automatically redirects to front page with pop-up window containing untagged images. Online collection database search is usable but returns unintelligible links that are database records.

Museum: National Museum of Australia

URL: http://www.nma.gov.au/

Comments: ALT text could be more meaningful, and there is an inaccessible calendar of events, but by and large, a fairly usable site.

Museum: Smithsonian Institution

URL: http://www.si.edu/

Comments: Mislabeled forms, use of inaccessible Java elements, pop-up windows, lack of ALT text on image maps, and misleading page titles.

Museum: The Guggenheim (Bilbao, Spain)

URL: http://www.guggenheim-bilbao.es/

Comments: Pop-up windows are unannounced, graphic links with no ALT text.

Museum: The Menil Collection

URL: http://www.menil.org/collections.html

Comments: Unlabeled graphic links, unannounced auto-refresh to a home page that contains links labeled Button 6, Button 8, Button 7, Button 3, Button 4 not in numerical order!

Museum: Whitney Museum of American Art

URL: http://www.whitney.org/

Comments: Site has insufficient user control options (font size is specified in style sheets) and inconsistent use of alt tags for graphics.

The following abbreviations are used in Table C-2: ASX, Advanced Streaming Format XML Redirector; MSAA, Microsoft Active Accessibility; SAMI, Synchronized Accessible Media Interchange; SMIL, Synchronized Multimedia Integration Language.

Table C-4 suggests ways to provide equivalent content. We suggest that you use these techniques in a nested manner starting at the top of the table. If each time you use one of the Flash attributes in the first column you include equivalent alternatives by means of the corresponding tag or method from the second column, you will improve the accessibility of your Flash content.

Table C-4. Techniques for Maximum Flash Accessibility

Flash Presentation Technique: Nested <object> elements

Provide Equivalent Content: At the lowest level

Flash Presentation Technique: <embed>

Provide Equivalent Content: <noembed>

Flash Presentation Technique: <script> to detect or launch
