<title>Live Regions</title>
|
|
<p>
|
|
A live region is a dynamically-updated portion of a web page, such as a
|
|
table of sports statistics, a list of current stock prices, a log from
|
|
a chat, or an alert displayed by the page you are reading. While live
|
|
regions appear quite frequently, fully accessible web pages with live
|
|
regions are encountered less often. This problem is actively being
|
|
addressed by a number of organizations.

<title>Live Region Politeness Levels</title>
|
|
<p>
|
|
Live regions have an associated "politeness" level which is set by the
|
|
author as a means to convey the importance of the information and to
|
|
suggest when users should be informed by their assistive technology of
|
|
updates made within that region. Live regions can be "off", "polite", or
|
|
"assertive" to the point of being "rude."

<title><app>Cthulhu</app>'s Support for Live Regions</title>
|
|
<p>
|
|
Because you might not agree with the politeness level specified by the
|
|
author whose page you are viewing, <app>Cthulhu</app> provides a number of
|
|
<link xref="commands_live_regions">live region commands</link> which
|
|
allow you to modify the level of any or all of the regions on a page.
|
|
In addition, you can:
