These networks have to grow and expand over a long period in order to truly overcome discipline and communication boundaries and to work together effectively. It is a logical consequence that it can only be of great advantage to start this process already at the beginning of the scientific career. This networking process is fostered by the forums and the innovative format Scientific Speed Dating, which has been carried out for the first time in December 2009 by the Forum Information Technology. At the forums’ invitation, 50 young researchers and scientists of RWTH Aachen University came together, all of them dealing with the topic of simulation in 536
the framework of their respective projects or dissertations. The event was supported by facilities of RWTH Aachen University which face this topic institutionally, as for example the graduate school AICES. Due to the participants’ positive feedback, further events of this kind shall follow. In the Scientific Speed Dating, participants are brought together in four phases: In the plenum, the participants present themselves for about one and a half minutes, using a presentation slide with brief references to their respective institute, subjectspecific background and current research topic. The next phase is the vis-à-vis situation indicated by the title of the event (see picture). Here, it is useful to create a link to the first presentation and to mutually explain current activities, results, problems etc. As a by-product, common questions and issues shall be filtered out and collected on a notice board. This process has to be realized within five minutes, since after that the conversational partner changes. The conclusion to the official part consists of the discussion of key issues from the vis-à-vis phase in small groups. Finally, phase four is designed as an informal get-together. Cooperation with the Gesellschaft für Informatik e.V. (GI) Based on a new cooperation between the Forum Information Technology and the Gesellschaft für Informatik (GI), since mid 2009 the manager of the forum is at the same time speaker of the Regional Group Aachen of the GI. With this he is integrated in the Germany-wide network of the GI Regional Groups. In the course of the cooperation the members of the GI Regional Group Aachen will be invited to public activities of the forum (e.g. Lecture Series). This will improve visibility of the forum and also attract more people to the forum’s events. Virtual Reality Center Aachen Ten years VRCA When in the late 90’s single RWTH institutes started to work on or with Virtual Reality, it very quickly became clear that high quality research on VR technology and methods requires teamwork within and across disciplines. Also, in order to develop VR solutions that should have the potential to serve as a powerful tool in the scientists’ work, a close collaboration between VR researchers and academic as well as industrial users is mandatory. As a consequence, in the year 2000, RWTH Aachen University founded the Virtual Reality Center Aachen (VRCA) as an interdisciplinary, non-commercial competence network in order to bundle, coordinate, and expand the Virtual and Augmented Reality (VR/AR) activities at the University and in the region of Aachen. Currently, more than 40 RWTH institutes from 6 faculties as well as 19 companies and external research institutions are organized in the VRCA. Not only the large number of VRCA members, but in particular the large number of projects presented in this progress report emphasize the research vitality and demonstrate the strategic importance of VR/AR in sciences. Joint projects that cross disciplinary boundaries create an atmosphere where complementary skills supplement each other in an ideal fashion. 537
