Developers may also create custom media controls for rich interactivity using CSS and JavaScript. These elements support playback natively in the browser using the browser’s built-in controls. No level 3 design tasks for this requirement?Īpple recommends using the HTML5 audio and video elements for mobile Safari.Confirm content interaction works with the screen reader.Check bypass blocks, consistent navigation, and multiple ways.Test using the IBM Equal Access Accessibility Checker browser extension or integration testing module to identify issues detected for this requirement.Note for iOS platform: For keyboards connected to iOS devices,Īpple has its own set of Tab and arrow keys behaviors as noted in Wireless Keyboard with VoiceOver.No level 3 developer tasks for this requirement.Make custom media player and animation controls keyboard accessible.Unit test - confirm component keyboard interaction.Follow core considerations in reducing effort.Implement keyboard operation for custom elements.Be familiar with established keyboard conventions.Use standard HTML elements where possible, using CSS to alter appearance not behavior.Where possible, achieve the desired tab order by adjusting the DOM, rather than overriding the tabindex.No level 3 design tasks for this requirement.People who are deaf, hard of hearing, or who have trouble understanding audio information also benefit because they can read the text alternative as a transcript of the audio or video information. The goal is to give a person who is blind or visually impaired the same information a sighted user would get from the media. #1keyboard app full#A full text alternative is a transcript that includes descriptions of all of the visual details, including the visual context, actions and expressions of the actors, and any other visual content, as well as the auditory information - the dialogue, who is speaking, sounds (as would be contained in captions).A narrator describes the important visual details that are not already explained in the soundtrack, including information about actions, text information not verbally described, who is speaking, facial expressions, scene changes, and so on. An audio description (also called video description or descriptive narration) is either added to the existing audio track during pauses in the existing audio content or on an alternate audio track.The visual information is described using one of the following: See Authoring Tools Accessibility Guidelines for more information. #1keyboard app software#Authoring tools include features in software that “authors” (developers, writers, etc.) use to to create or modify content. Non-web documents: Use this filter for support documentation, learning, and marketing materials that are not integrated into a web-based application or are provided separately, such as PDF, DOCX, PPTX, and XLSX formatted attachments.Īuthoring tools: Use this filter to view specific requirements that cover both the end-user features of an application that promote the generation of output, and the accessibility of the output itself. Web documents: Use this filter for support documentation, learning, videos, and marketing materials that run in a browser, such as HTML and EPUB. Non-web software: Use this filter for all software that is not web-based, such as native mobile apps, Windows® and MacOS® desktop, and command-line software. Web: Use this filter for a web site or application that runs in a browser. The resulting filtered set of requirements include criteria from WCAG 2.1, US Revised 508 Standards, and European EN 301 549 standards: Use these filters to narrow down and understand the list applicable to your project. A key aspect of all digital technologies - whether web, software, or documentation - is that the user interface needs to conform to applicable criteria in the IBM accessibility requirements.
