  1. Information Visualization Using 3D Interactive Animation George G Robertson, Stuart K Card, and Jock D. MacKinlay Presented by David Wang CMSC838F: Information Visualization

  2. Goal and Motivation • Seek successor to UI using Desktop metaphor • Hardware prices dropping, performance rising • What is there aside from WIMP CMSC838F: Information Visualization

  3. Strategies • Making User workspace larger • Enabling user interaction with multiple Agents • Increasing real-time interaction rate between user and system • Provide visual abstraction to speed information assimilation and retrieval CMSC838F: Information Visualization

  4. Identified Problems • Multiple Agent Problem • Animation Problem • Interaction Problem • Viewpoint Movement Problem • Object Movement Problem • Small Screen Space Problem CMSC838F: Information Visualization

  5. Workspace • More screen space. Rooms. Multiple desktops. • Denser screen space. Animation and 3D. CMSC838F: Information Visualization

  6. Agents • Search Agents • Clustering Agent • Interactive Objects CMSC838F: Information Visualization

  7. Real-time Constraints • Tune to Human Constants • Cognitive Coprocessor Scheduler and Governor CMSC838F: Information Visualization

  8. Visual Abstractions • Hierarchical Structure -> Cone Tree • Linear Structure -> Perspective Wall • Continuous Data -> Data Sculpture • Spatial Data -> Office Floor plan CMSC838F: Information Visualization

  9. Cone Tree CMSC838F: Information Visualization

  10. Cone Tree (Compaq Research) CMSC838F: Information Visualization

  11. Perspective Wall CMSC838F: Information Visualization

  12. UI Architecture Application (Visualizers) 3D Navigation 3D Rooms Interactive Objects Animation Loop Governor Task Queue Display Queue User CMSC838F: Information Visualization

  13. Strengths • Formalizes and defines tasks that a next-generation 3D Animated UI would have to perform. CMSC838F: Information Visualization

  14. Weaknesses • Sorry. The “future” didn’t happen as envisioned.  • The desktop paradigm, augmented with the “web paradigm” survives. WIMP still rules.  CMSC838F: Information Visualization

  15. Favorite Sentence • In the 1990’s, it is likely that information access will be a primary force in shaping the successor to the desktop metaphor. CMSC838F: Information Visualization

  16. Update to the UI Paradigm • Web Book and Web Forager. • Card, Robertson, York. 1996. CMSC838F: Information Visualization
