About Me

I am a senior research assistant ("Oberassistent"), leading the GeoGazeLab at the Chair of Geoinformation Engineering at the ETH Zurich, Switzerland. My teaching in Zurich is mostly related to mobile geographic information systems (GIS).
Previously, I was a research and teaching assistant at the Chair of Computing in the Cultural Sciences (University of Bamberg, Germany) where I received my PhD in 2011 (Dr. rer.nat.).

Research Interests

Some keywords for the quick reader:
  • Mobile GIS and Mobile Assistance
  • Spatial Cognition, Mobile Decision Making, and Wayfinding
  • Geographic Human Computer Interaction, specifically using gaze as input
  • Learning in Space, Spatial Technologies for Learning
  • Interpretation of Mobile Behavior, Mobile Intention Recognition
  • Location-Based Games: Theory, Design, Edutainment
My research focuses on the improvement of mobile GIS and location-based services. I'm interested in people's attention and intentions while using these systems, and in new assistive technologies that can help to improve the interaction with mobile geo-spatial services.
In my current work, I'm using Mobile Eye Tracking technology to analyze people's perception and visual strategies while interacting with geographic information, especially in mobile decision situations. Secondly, I'm developing methods for the semantic interpretation of a mobile person's gaze and trajectory, leading to mobile gaze-based assistive technologies.
At the intersection of artificial intelligence and geographic information science, my PhD on Mobile Intention Recognition was concerned with the semantic interpretation of an agent's spatio-temporal behavior. For this purpose, I developed a "spatialized" version of Tree-Adjoining Grammars, a formal grammar originally used in natural language processing.
