  1. pathfinderfocus+context for java program navigation Mik Kersten University of British Columbia UBC CS-533C Presentation, 2004-04-21

  2. background • Overview+details views are limited • Navigation structure is not explicit • Editor tabs shrink • Navigation history is a flat list • Idea • Model degree of interest (DOI) • Represent user navigation • Leverage program structure UBC CS-533C Presentation, 2004-04-21

  3. Attempts UBC CS-533C Presentation, 2004-04-21

  4. Inspiration • Tufte, Envisioning Information p.91 UBC CS-533C Presentation, 2004-04-21

  5. implementation • User monitor: navigation and IDE lifecycle • Map manager: DOI model and persistence • Pathfinder drawing: visualization • Pathfinder view: main UI component UBC CS-533C Presentation, 2004-04-21

  6. Lessons learned • Tight IDE integration is key • Need to augment existing views • Some views could be hidden • Predictability is important • Files appear/disappear frequently • Where to look needs to obvious • DOI stability is hard • Screen-estate effects • User-task effects • Current parameters are hand-tuned UBC CS-533C Presentation, 2004-04-21

  7. Future work • Improving DOI function & user modeling • Representing more structural relationships for OOP and AOP • Surfacing more structure, guaranteed visibility of highest DOI • Moving down to member granularity & providing semantics-based zooming • Sharing of models and awareness of others’ DOI for collaborative development UBC CS-533C Presentation, 2004-04-21
