3.3.2 Location in Hierarchy: The user can view the path of nodes leading from the root of any content hierarchy in which the structure and semantics are implied by presentation, as opposed to an explicit logical structure with defined semantics (Level AA).Simon Harper, 8 Mar 2010, 12:05:56
* Intent of Success Criterion 3.3.2:
Knowing where you are in a hierarchy (e.g., tree node, nested frame) makes it easier to understand and navigate information. Users who are perceiving the data linearly (such as audio speech synthesis) do not receive visual cues of the hierarchical information. Within constructs that have explicit logical structure such as a Java Tree node, navigation is tied to a users understanding of what that construct actually represents. With a tree node made of individual HTML and script layered with styling, the user has no idea what the combined individual components mean, and therefore does not know how to navigate the hierarchy or what to expect once interaction is underway. Efficient navigation of hierarchical information reduces keystrokes for people for whom keypress is time-consuming, tiring, or painful. For people with some cognitive disabilities, providing the clear hierarchy reduces cognitive effort and provides organisation.
* Examples of Success Criterion 3.3.2:
o A media player provides a hierarchical display of playlists, albums, artists and songs, etc. When the user selects an individual item, a breadcrumb of the categories is displayed, can be navigated and is available programatically.
