上海时时乐走势图:Mobile Accessibility at W3C
More than “Mobile”
“Mobile accessibility” refers to making websites and applications more accessible to people with disabilities when they are using mobile phones and other devices. WAI’s work in this area addresses accessibility issues of people using a broad range of devices to interact with the web, including:
- phones and tablets
- digital TVs
- wearables such as smart watches
- devices in car dashboards and airplace seatbacks
- devices in household appliances and other “Internet of Things”
- and more
It address a wide range of issues, including:
- small screen sizes
- different input modalities, including voice and 3D touch enabled by pressure sensors
- device use in a different settings, such as bright sunlight
- and more
W3C WAI Addresses Mobile Accessibility
WAI’s accessibility standards address mobile accessibility:
- WCAG (Web Content
Accessibility Guidelines) covers web pages and web applications,
including content used on mobile devices.
- To learn how WCAG 2.0 can be applied to mobile web content, mobile web apps, native apps, and hybrid apps using web components inside native apps, see Mobile Accessibility: How WCAG 2.0 and Other W3C/WAI Guidelines Apply to Mobile.
- A more general resource that also includes mobile apps is WCAG2ICT: Applying WCAG 2.0 to Non-Web Information and Communications Technologies.
- WCAG 2.1 will have additional requirements related to mobile accessibility. We expect to complete it in 2018. The in-progress Working Draft is available: WCAG 2.1 Working Draft
- UAAG (User Agent Accessibility Guidelines) covers web browsers and other ‘user agents’, including mobile browsers.
- ATAG (Authoring Tool Accessibility Guidelines) covers software used to create web pages and applications, including for mobile.
- WAI-ARIA (Accessible Rich Internet Applications) defines ways to make web content more accessible, especially dynamic content and advanced user interface controls. It applies to web applications and to accessing websites with mobile devices.
WAI’s Education and Outreach Working Group (EOWG) is developing a Mobile Accessbility Introduction with guidance for designers and developers. We expect it to be completed in late 2018.
W3C addresses mobile accessibility. WAI ensures that the core W3C technologies support accessibility, including those that are essential for the mobile web. All W3C work is reviewed for accessibility by WAI’s Accessible Platform Architectures Working Group (APA).
W3C work on mobile includes Mobile Web Application Best Practices, Mobile Web Best Practices, and mobileOK Checker. For a summary of technologies developed in W3C that increase the capabilities of web applications and how they apply specifically to the mobile context, see Standards for Web Applications on Mobile.

General information is available in Participating in WAI.
Most of WAI’s work related to mobile accessibility is through the Mobile Accessibility Task Force. If you would like to be more involved in WAI’s work on mobile accessibility, please send an e-mail with information about your interests and time availability to the Task Force facilitators Kathy Wahlbin and Kim Patch.
