The professorship for Human-Computer Interaction (established as a junior professorship for practical computer science) at the University of Trier is part of Department IV - Computer Science and is assigned to computer science there. With a scientific focus on the use of interactive systems in everyday work contexts, the Human-Computer Interaction Group team works on scientific investigation and the development of technical, computer-based solutions, in particular using virtual and augmented reality technologies. The human being as the user of these systems is in the foreground of the scientific and interdisciplinary examination of this subject area. Furthermore, the group works with formal modeling methods to develop interactive systems, which not only enables the description but also the formal validation of these systems. The current research fields (see Figure C.1) of the working group can be divided into two main areas of work and science & teaching, which in turn are each divided into two sub-areas.
