1	Agileviews: A Human-Centered Framework for Interfaces to Information Spaces Gary Marchionini INLS 357
2	Information Perspective Search is embedded in real life tasks Search is both analytical and interactive People and needs are diverse Vision is both a primary channel and a metaphor
3	Design Provenance Direct Manipulation (Shneiderman, 1983) Visible objects and actions Rapid, reversible, incremental actions Dynamic queries Xerox alto, Apple Lisa, Macintosh & GUIS & WIMP interfaces (1979+) Hypertext (Bush, 1945; Nelson, 1974) Links are first class objects Games and visualizations (lunar lander 1960s, Atari Pong, 1972); VR (Engelbart--radar; Sutherland—simulations) See http://www.designboom.com/eng/education/pong.html for history of games
4	Views A view is a partition of an information space There are many possible partitions for any space since many attributes may be used to ‘slice and dice’ the space People should be able to effortlessly change views Focus can change based on granularity Focus can change based on attribute
5	Agile Views Framework
6	Theory to Practice Design challenge 1: creating views What granularities (collections and items) Which attribute sets? Creating or extracting metadata Design challenge 2: manipulating/controlling views Perceptual estimation (e.g., look ahead) Physical and conceptual inertia
7	Three Examples Relation Browser Federal statistics, overviews of relationships (several different partitions). Useful for small number of attribute sets, each with small number of attribute values. Backend database of metadata, Java applet interface (Ben Brunk, Junliang Zhang) Enriched Links Complex web sites, previews, overviews, and reviews of pages. Backend computation and Javascript interface (Gary Geisler) Integrated overviews and previews Multimedia digital library, backend computation, Java applet interface (Wei Ding, Gary Geisler)

16	One of many previews: Open Video
17	Give People Flexibility! Multiple views require rich and accessible metadata Control mechanisms are kludges in today’s WWW environment A click is a terrible thing to waste!
