  26. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Interactive Visualization Java Swing: User Interface GUI SCENE Toolkit of basic reusable software components GEO Java2D / 3D: Math and Gfx Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  27. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Components Java Swing GUI SCENE GEO Java2D / 3D Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  28. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Components • split off construction part into “Constraints” eg. point on line • split off visual part of objects into “Renderers” e.g. straight, dotted or shaded line Java Swing GUI SCENE GEO Java2D / 3D Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  29. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Components • split off construction part into “Constraints” eg. point on line  automated updates of dependencies (data flow model)  algorithms become replaceable  reusable • split off visual part of objects into “Renderers” e.g. straight, dotted or shaded line  same as above Java Swing GUI SCENE GEO Java2D / 3D Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  31. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Components • compose scene as hierarchical “Scene Graph”  default actions e.g. render, pick, drag, zoom • new objects as sub graph with basic objects e.g. point set uses points provide specialized GUI e.g. textual scalar input Java Swing GUI SCENE GEO Java2D / 3D Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  32. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Embedding into Hypermedia • Scripting Interface • import user-defined classes • instantiate new objects • call methods • bind scripts to specialized GUI Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  33. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Embedding into Hypermedia • Scripting Interface • import user-defined classes • instantiate new objects • call methods • bind scripts to specialized GUI • programming with browser functionality • enables untrained authors to modify scripts • e.g. adapt to context • set state to current text / illustration • match visualization by exchanging renderers • switch constraints to compare algorithms Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

Steer design/layout by templates •  decentralized development by multiple authors •  editorial & rating system •  set of “registered scripts” Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  39. Case Studies Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE

  40. Netties/NLT 2001: Scripting and Cooperation for Interactive Web-based Courseware Conclusion • we focused on • adequate embedding • of virtual experiments • into hypermedia courseware •  adapt to context •  scripting •  generalize to multi-user model Frank.Hanisch @ WSI-GRIS.Uni-Tuebingen.DE
