http://www.w3.org/Bugs/Public/show_bug.cgi?id=13619 Summary: Provide access to global accessibility settings Product: HTML WG Version: unspecified Platform: All OS/Version: All Status: NEW Keywords: a11y, a11ytf Severity: normal Priority: P2 Component: HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: gcl-0039@access-research.org QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org, public-html-a11y@w3.org Depends on: 13617 HTML5 should define a standard, platform-independent way for content to query the user agent's accessibility settings, and by extension platform settings that are known to the user agent. This is one aspect of allowing HTML-based content and applications provide accessibility support equal to and consistent with the platform and native applications, and can avoid situations where their default settings make HTML-based applications inaccessible. We note there are privacy concerns that must be addressed. For example, companies should not be able to infer the disabilities of visitors to their web site by querying the user's accessibility settings. However, this is just one example of a broader issue that needs to be addressed, and is covered by bug 13617. Use case: Yev turns on his operating system's High Contrast option. This option is supported by all major operating systems and tells software the user wants high contrast between foreground and background. In his browser he loads a web-based flow chart editor that displays all its document content in an HTML5 canvas element. The flow chart editor wants to detect when the user has high contrast mode turned on so it can adjust its graphical display appropriately. Because it's designed to run on any browser and any operating system, it needs a platform-independent means of querying this setting. Use case: Amanda has turned on the "Show Extra Keyboard Help" option in the Windows Control Panel, which tells all software that she wants any and all options that enhance keyboard access to be automatically enabled. Her web browser responds to this setting by, for example, always displaying the underlined access keys in menu and control labels. She would like web pages and web apps to also respond to this setting, even if they're creating custom controls. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
