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. |

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 Provide Equivalent Content: <noscript> | |
