Usability & Web Accessibility – Multimedia

It is necessary for video and multimedia to include synchronized captions and transcripts. If a video has narration, it is also best practice for narration to describe the actions in the video, such that a blind person listening to the video can understand what is happening on the screen.

Android accessibility: roles and TalkBack

TalkBack only announces role information for a relatively small number of user interface (UI) elements within native apps. When comparing this behaviour against web content, this can often give the (false) impression that these elements must have been coded incorrectly and therefore need to be “fixed”.

Usability & Web Accessibility – PDF – Frequently Asked Questions

While the decision often depends on the nature of the PDF document, web pages in general are easier to create and maintain accessibly. This is especially true for interactive documents, such as forms. Site owners should in general prefer to create content as web pages unless there is a compelling reason to provide the content in some other medium. Site owners can also provide content both in a web page and a PDF, with a PDF download available on the page itself.

Usability & Web Accessibility – Testing Procedures

Checklists are a necessary and helpful part of any accessibility testing process. The best checklists translate WCAG criteria into understandable language. Checklists may also be role-specific, focusing on editors, designers, or developers. Though checklists are not a perfect substitute for understanding WCAG guidelines, they are nevertheless invaluable.

Usability & Web Accessibility – Using University Supported Platforms

Site owners should consider using university-supported platforms for their sites. University-supported platforms include YaleSites and Tridion. Yale staff regularly update these platforms for accessibility, security, and functionality. Hence, using these platforms may make compliance easier.
