By varying the levels of detail associated with items in an ordered
collection of information, items may be organized in a way to emphasize
details about item of current interest. Displaying varying levels of
detail about items in an ordered collection of information involves
determining a focus, and based on their relative location to the focus
adding additional detail to other items displayed from the collection of
information. For instance, a user browsing a web search results list
typically only sees a few essential details such as the name, link, and
brief abstract about each item in the list. Providing the user with
varying levels of detail about each item in the list helps them decide to
where they want to navigate.
