The Seven Tasks for Visual Information Environments By Ben Shneiderman (1996):
- Overview Gain an overview of the entire collection
- Zoom Zoom in on items of interest
- Filter Filter out uninteresting items
- Details-On-Demand Select an item or group and get details when needed
- Relate View relationships among items
- History Keep a history of actions to support undo, replay, and progressive refinement
- Extract Allow extraction of sub-collections and of the query parameters
“Overview first, zoom and filter, then details-on-demand”
