Mobile Accessibility

Summary

• Mobile accessibility is covered in existing W3C WAI accessibility standards/guidelines, particularly WCAG and UAAG, which are introduced below. There are not separate guidelines for mobile accessibility.
• W3C is developing more specifc and updated guidance on mobile accessibility.
• WAI's Mobile Accessibility Task Force work includes:
  • Mobile Accessibility: How WCAG 2.0 and Other W3C/WAI Guidelines Apply to Mobile
  • Potential new WCAG Success Criteria and Techniques

Introduction

"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: phones, tablets, TVs, and more.

This page summarizes existing resources and resources under development that are related to mobile web accessibility.

Current Work is listed below.

W3C WAI Addresses Mobile Accessibility

WAI's accessibility guidelines address mobile accessibility:

• WCAG (Web Content Accessibility Guidelines) covers web pages and web applications, including content used on mobile devices.
  • WCAG2ICT Applying WCAG 2.0 to Non-Web Information and Communications Technologies coverage includes mobile apps.
  • 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.
  • To learn how WCAG addresses similar issues as Mobile Web Best Practices and Mobile Web Application Best Practices, see Shared Web Experiences.
• UAAG (User Agent Accessibility Guidelines) covers web browsers and other 'user agents', including mobile browsers.
  • For examples of how web browsers that follow UAAG benefit people with disabilities using the Web on mobile devices, see Mobile Accessibility Examples from UAAG.
  • A rough draft of Applying UAAG to Mobile Phones is available.
• 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.

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, mobileOK Checker
• WAI's IndieUI (Independent User Interface) worked on ways for user actions to be communicated to web applications, including mobile applications. It is being taken up by other W3C groups as described on the IndieUI home page.
• Standards for Web Applications on Mobile summarizes technologies developed in W3C that increase the capabilities of web applications, and how they apply specifically to the mobile context.

Current Work

WAI's current work related to mobile accessibility includes:

• WCAG techniques and other guidance for designers and developers through the Mobile Accessibility Task Force, including:
  • Mobile Accessibility: How WCAG 2.0 and Other W3C/WAI Guidelines Apply to Mobile
  • Potential new WCAG Success Criteria and Techniques
  • Other Current Work
• WAI-ARIA (Accessible Rich Internet Applications) - See the WAI-ARIA Overview for an introduction and links to the draft documents.
• Reviewing Standards for Web Applications on Mobile through the Accessible Platform Architectures Working Group (APA).

Get Involved

General information is available in Participating in WAI.

Mobile and Accessibility Overlap

Most of this page addresses people with disabilities using mobile devices. We also have related resources that address situations such as: a web development project wants to make their websites and web applications work better for all mobile users (including those without disabilities) and also work better for users with disabilities using "traditional" computers.

• Web Content Accessibility and Mobile Web: Making a Web Site Accessible Both for People with Disabilities and for Mobile Devices introduces the significant overlap between making a website accessible for a mobile device and for people with disabilities. Provides a brief overview that is useful for the business case.
• Shared Web Experiences: Barriers Common to Mobile Device Users and People with Disabilities provides examples of barriers that people with disabilities and people using mobile devices experience when interacting with web content. It is organized by the principles perceivable, operable, understandable, and robust, and includes links to the relevant sections of MWBP (Mobile Web Best Practices) and WCAG (Web Content Accessibility Guidelines).
• Relationship between Mobile Web Best Practices (MWBP) and Web Content Accessibility Guidelines (WCAG) provides guidance for people who are familiar with MWBP and want to know how it relates to WCAG, or are familiar with WCAG and want to know how it relates to MWBP.

About W3C and WAI

The World Wide Web Consortium (W3C) is an international consortium where Member organizations, a full-time staff, and the public work together to develop Web standards. W3C primarily pursues its mission through the creation of Web standards and guidelines designed to ensure long-term growth for the Web. To learn more, see About W3C.

W3C's Web Accessibility Initiative (WAI) brings together individuals and organizations from around the world to develop strategies, guidelines, and resources to help make the Web accessible to people with disabilities. To learn more, see the WAI website.
