Research of the Virtual Worlds and Digital Games Group is focused on technologies and applications of Mediated Reality.

Mediated Reality is concerned with the technology-based alteration of the individual perception of the environment. On the one hand, this might be realized by integrating additional virtual content into the reality, not recognizable as artificial content by the observer (using Augmented Reality). On the other hand, objects might be removed from reality, impossible to be detected by user (using Diminished Reality). We investigate into those and other technological aspects, as well as application areas of mediated realities.



Base technologies required to realize a mediated environment researched in our group include:

  • Augmented Reality
  • Diminished Reality / real-time video inpainting

  • Computer-vision based tracking
  • Global real-time lighting

  • Natural user interfaces


Application areas

Enabling technologies for mediated realities might be used in a large variety of application scenarios. As part of our research we currently focus on:

  • Digitale Games (Mixed Reality Games / Pervasive Games/Alternate Reality Games)

  • Video editing and manipulation tools



Within student projects (with students with a social science of economic background) we also investigate into implications of mediated realities. This includes:

  • Usage and acceptance
  • Market studies and analysis

  • Ethical issues
