W3C Editor's Draft, 17 April 2008

Introduction

Incomplete draft: This document is an experimental editor's copy that has no official standing and is incomplete. It is provided for review and feedback only. Please send feedback to public-bpwg-comments@w3.org (archive).

Comment: Reviewers please bear in mind. This page is for those who have done MWBP and are moving to WCAG 2.0. It answers the question “I'm thinking of doing a bit of WCAG, but is it really justified for my mobile users?”. The pages of this document will remain drafts for now, work concentrating on the “compliance” pages as a seperate document (example of compliance page). The navigation bar at the top shows the structure of the set of pages.

This page describes how different Web Content Accessibility Guidelines can help the general user in the mobile context above and beyond the special benefit for users with disabilities. Mobile users may benefit from the Web Content Accessibility Guidelines as do users with disabilities. However, this paragraph focuses on the extra benefits for the special needs of the general user of mobile devices. Checkpoints and guidelines that have no specific benefit for mobile users beyond that experienced by the user with disabilities are listed at the end of the page.

Comment: ... The WCAG 2.0 Success Criteria numbers are linked to the corresponding section of the WCAG 2.0 Quick Reference...

Below is a list of the SCs described in detail in this section. Each name is a link to the detailed description that follows. SCs that are believed to have no added benefit for Mobile Web users are listed at the end for completeness.

1.1.1 Non-text Content (Level A)

WCAG requires a text equivalent for all non-text content, including images. This enables users in the mobile context to read content without downloading images.

1.2.1 Captions (Prerecorded)

Mobile devices are often used in situations with significant background noise that makes it difficult to hear the audio track of multimedia content. It public places it may be socially unacceptable to listen to the soundtrack. Captions enable the user to understand the multimedia content in these situations.

1.4.1 Use of Color

Many mobile devices have monochrome screens, often do not have good color contrast and are often used in less-than-ideal lighting conditions, and so like non-visual users or those with colour perception deficit they may be unable to percieve information conveyed by colour. This success criterion ensures that users who cannot perceive colour correctly for whatever reason will be able to understand and operate the content.

0.0.0 (other success criteria follow)
