Institute of Visual Computing (IVC)
Scientists from H-BRS at the IEEE VR 2025 in Saint-Malo, France
Successful workshop on optimising graphics and displays in VR and AR based on human perception
Dr Alexander Marquardt, research assistant at the Institute for Visual Computing (IVC) at H-BRS, took part in the ‘Second International Workshop on Perception-driven Graphics and Displays for VR and AR’ (PerGraVAR) together with alumnus Prof Dr Martin Weier and other colleagues. The workshop, which dealt with the optimisation of graphics and displays based on human perception in virtual and augmented reality, met with great interest and attracted around 30 participants. The keynote speeches by Qi Sun (New York University) and Ana Serrano (Universidad de Zaragoza), who presented current developments in VR research, were particularly impressive.
Research into thermal feedback for emotional VR experiences
Another highlight was the poster contribution by H-BRS in collaboration with the Nara Institute of Science and Technology and the University of Bonn. The contribution, entitled ‘Temperature Matters: Thermal Feedback for Awe Experiences in VR’, shed light on how thermal stimuli on the head, such as heat and cold stimuli, can be used to trigger emotional reactions such as awe in virtual environments. The poster contribution was presented by Marvin Lehnort, a research assistant at H-BRS.
AI avatar in virtual reality
As part of an innovative research demonstration, Alexander Marquardt presented an advanced AI avatar together with AI experts Daryoush Vaziri and David Golchinfar from VAGO Solutions. The avatar uses a combination of large language models (LLM) and RAG technologies to customise knowledge in virtual worlds and convey expert knowledge in a simple way. The approach was met with great interest by the testers and was rated as extremely promising for future applications in the VR world. The technology was developed by VAGO Solutions and scientifically supported at H-BRS.
Cooperation with AI start-up VAGO Solutions
The innovative technology of the AI avatar was developed in collaboration with the AI start-up VAGO Solutions. The research and scientific support was carried out in close partnership with the IVC at H-BRS. A successful example of the close integration of applied research and start-up innovation.
H-BRS's presence at IEEE VR 2025 demonstrates the university's commitment to advancing cutting-edge research in the field of virtual reality and actively participating in international discussions and developments.
