Tight Coupling of Dynamic Query Filters with Starfield Displays Spotfire net Desktop By Chris Ahlberg and Ben Shneiderman Spotfire Inc IC280 5 9 02 Jeff Ridenour Principles of Direct Manipulation for VIS applications visual representation of the world of action including both objects and actions rapid incremental and reversible actions selections by pointing not typing immediate continuous display of results New VIS designs Dynamic Query Filters Starfield Display Tight Coupling Dynamic Query Filters Query parameters are rapidly adjusted with sliders buttons etc Each query component acts as a filter reducing the number of items in the result sets Effects were combined using simple AND logic Starfield Display Scatterplot with additional features to support selection and zooming Result sets are continuously available and support viewing of hundreds or thousands of items Tight Coupling Query components are interrelated in ways that preserve display invariants and support progressive refinement Specifically outputs of queries can be easily used as input to produce other queries Aspects of Tight Coupling Comprehensible and consistent affordances to guide users highlights handles scrollbars etc Rapid incremental and reversible interactions among components Constraints on permissible operations to preserve display invariants and prevent errors Continuous display to always show the users Spotfire net Desktop Tool to Access Analyze and Publish Documentation emphasizes Web features and Online Services business model Visual Tip Tool for rapid asessment of potentially intersting visualizations Large number of 2D scatterplots ranked by correlation of attributes Visualizations 2D scatter plots 3D scatterplots Rotate Zoom Roll etc Histograms Bar Charts Line charts Profile Charts Parallel Coordinate Techniques Pie Charts
