AgileViews
AgileViews is a framework for designing interfaces for information
seeking. This framework is based on the idea that we can improve
information seeking by providing users with agile control over information
spaces through the use of alternative views and simple mechanisms
for coordinating these views. By explicitly defining and coordinating
overviews, previews, peripheral, and shared views, in addition to
content-specific views, we hope to produce interfaces that enable
users with diverse backgrounds and information needs to effectively
find the information they need.
While
information seeking often entails some degree of trial and error,
the Web clearly exemplifies the need for interfaces that can reduce
the time and cognitive effort people expend finding information.
An early implementation of the AgileViews idea, a system called
Enriched Links, did this by providing people with informationpresented
in small pop-up visualizations, or agile viewsabout associated
resources represented by hyperlinks. Users activate the agile views
simply by moving the mouse over a hyperlink, which causes a pop-up
window to appear next to the link (shown to the right). The pop-up
window provides immediate, intuitive access to several types of
views, such as a thumbnail preview of the linked page; information
about the page's title, filesize, and last update; and its access
history. By examining one or more views, users can quickly evaluate
the potential relevance of a linked resource to their particular
information seeking need before the user spends the time and cognitive
effort of navigating to the resource and waiting for it to load.
The use of the multiple views easily accessed is modeled on basic
characteristics of human information processing and the way humans
intuitively use views in the physical world. Just as in the real
world people quickly and smoothly change their focus from a distant
to a close-up to a peripheral view, we believe that in the digital
world people should be able to focus on the view that provides the
type of information most appropriate for their unique context and
information seeking needs. We are currently working on an interface
for video browsing based on the AgileViews framework. The example
below shows how a user can browse an overview of a video collection
and easily focus on the aspect of the collection that is of most
interest. Here the user is browsing the overview by genre, but the
overview can be browsed by characteristics such as color and sounds
as well.
