Service-Oriented Information Visualization for Smart Environments

Smart environments consist of several interconnected devices. The device ensemble can change dynamically as mobile devices enter or leave the environment. To utilize such environments efficiently for information visualization, we propose a service-oriented architecture.Various services run on different machines and visualizations are generated dynamically depending on the environment´s current situation. The necessary adaptation to available output devices is driven by instantiation of different service implementations, by parameterizing service invocations, and by adapting the visualization pipeline at run-time. We implemented a prototype that provides parallel coordinates, scatter plot matrices, and a map display.
