Former Research Associate

Dr Julian Frommel

Julian Frommel joined the Institute of Media Informatics in October 2014. He studied Computer Science and Multimedia at Augsburg University and acquired his master degree with a master's thesis on "Learning Bayesian Networks From Multimodal Data to Control the Behaviour of Virtual Characters" at the Human-Centered Multimedia group of Prof. Dr. Elisabeth André. His current research interests revolve around novel interaction concepts for games and their influence on players. In specific he is interested in emotion-based game adaptivity, the assessment of the player state, interaction and game design of VR and AR games, as well as serious games.

Mr Frommel has left the institute in October 2019 after having concluded his phd thesis. We thank him for his excellent contributions and wish him all the best to his future career.

  • ShareVR

    ShareVR is a proof-of-concept prototype using floor projection and mobile displays in combination with positional tracking to visualize the virtual world for the Non-HMD user, enabling them to interact with the HMD user and become part of the VR experience.


  • Beer Crate Routing

    Beer Routing – was developed as part of the project Game Design and Development: Professor Insanity attempts to improve the situation at his favourite bar. For this purpose, he teaches the waiter - i.e. the player - the Dijkstra algorithm and other routing strategies for optimal beer distribution.

    Student team: Jonas Kraus, Matthias Mak, Philipp Speidel, Fabian Widmann

  • 2084 - Safe New World - A Pervasive Game

    2084. Terrorism: under control. Work: performed by machines. Euro and dollar: collapsed. The only remaining currency: personal data.

    That is the scenario of this pervasive game, developed as part of the Ubiquitous Computing project. Did you always want to experience the feeling of being shadowed in your everyday life? Do you want to test your ability to unobtrusively follow other players? This is your chance to experience the safe new world, where everybody spies on everyone.

    Student team: Maximilian Baer, Thomas Dreja, Christian Hunger & Julian Winterfeldt

  • Serious Games – Skill Advancement Through Adaptive Systems

    This project is funded by the Carl-Zeiss-Foundation and examines the areas of complex problem solving of players, as well as strategies and techniques for development thereof. The goal of this project is to develop an internationally visible centre for interdisciplinary serious games research at Ulm University that studies application oriented basic research on that topic.
