Fraunhofer IGD develops in the context of the joint project VIntEL (Distributed Integrated test environment) in cooperation with Fraunhofer IOSB (former IITB) and the Federal Ministry of Defense (BWB) innovative user interfaces and visualizations for representing semantic relations in different domains. Within two project iterations already three different visualizations for interacting with semantic information were provided to the project partners. In this context the main focus is on the handling of complex contents and a system based on the SemaVis-Framework could be developed that allows an intuitive interaction with these complex data structures. In the ongoing third project iteration semantic visualizations are integrated in the VIntEl system to allow a seamless data access and to exhaust the benefit of graphical visualizations.
