The old skool WCAG 2x definition of a web page<\/em> is not fit for purpose when WCAG is used to test non web user interfaces as it is, for example native apps<\/a> it leads to suboptimal outcomes. There has been much work done in the past and in the present to define a view for conformance purposes. This effort is currently ongoing as part of W3C Accessibility Guidelines Working Group WCAG 3<\/a> work<\/p>\n WCAG 3 definition of a view<\/em><\/a><\/p>\n Testing scope that includes all\u00a0content<\/a>\u00a0visually and\u00a0programmatically<\/a>\u00a0available without a significant change. Conceptually, views correspond to the definition of a web page as used in WCAG 2, but are not restricted to content meeting that definition. For example, a view could be considered a \u201cscreen\u201d in a mobile app or a layer of web content, such as a modal dialog.<\/p><\/blockquote>\n This definition is all a bit wooly.<\/p>\n Conformance scope that includes all\u00a0content<\/a>\u00a0visually and\u00a0programmatically<\/a> available without a change of context<\/strong><\/p>\n I have tweaked the WCAG 2.2 definition of change of context and related definitions,<\/p>\n Major change in the content of the view that, if made without user awareness, can disorient users who are not able to view the entire view simultaneously A change of content is not always a change of context. Changes in content, such as an expanding outline, dynamic menu, opening a non-modal dialog, or a tab control do not necessarily change the context.<\/p>\n Example:\u00a0<\/em>Opening a new window, opening a modal dialog, going to a new view (including anything that would look to a user as if they had moved to a new view) or significantly re-arranging the content of a view are examples of changes of context.<\/p>\n object in which the user agent presents content<\/p>\n The\u00a0user agent\u00a0presents content through one or more viewports. Viewports include windows, frames, loudspeakers, and virtual magnifying glasses. A viewport may contain another viewport (e.g., nested frames). Interface components created by the user agent such as prompts, menus, and alerts are not viewports.<\/p>\n This definition is based on the WCAG 2.2 definition of viewport<\/a>.<\/p>\n any software that presents content for users<\/p>\n Example:<\/em> Web browsers, media players, plug-ins, and other programs or apps \u2014 including assistive technologies<\/a> \u2014 that help in rendering, and interacting with content.<\/p>\n This definition is based on the WCAG 2.2 definition of user agent<\/a>.<\/p>\n If you have comments on this please add them to this Discussion on defining view<\/a><\/strong><\/p>\nThe current WCAG 3 definition of view<\/h2>\n
