ExplorViz uses dynamic analysis techniques to provide live trace visualization of the communication in large software landscape. It targets system and program comprehension in those landscapes while still providing details on the communication within an application. A landscape perspective enriches current system visualizations with additional abstraction levels for efficient comprehension of communication between hundreds of applications which is often encountered in, for instance, Cloud environments. On the application level perspective, ExplorViz utilizes the 3D city metaphor combined with an interactive concept of showing only details that are in focus of the analysis. For best accessibility, ExplorViz is a web-based tool featuring cutting-edge technologies like WebGL and HTML 5.
Given the 3D city metaphor visualization of an application, we investigate new interaction styles and higher immersion for a more effective and efficient program comprehension process. For this purpose, we utilize uprising technologies and evaluate developed approaches in experiments with real test subjects.
The usability and effectiveness of ExplorViz has been investigated in controlled experiments which resulted in increased efficiency and effectiveness over competing approaches.
