My Work

I am observing the way people look at things. My research at the University of Tübingen (and formerly also at the University of Aalen) is about the process of visual exploration - by which we explore our surrounding, prepare our actions and reveal our intentions. My algorithms enrich the data recorded with an eye-tracking device and make it not only look fancy, but give us insight on the fundamental principles of human visual and cognitive behavior.

Eye movement patterns

What do scanpaths tell us? How they differ between subjects, tasks and experience. And ho to do machine learning on eye-tracking data.

Eye Tracking

Everyone can do eye-tracking in the lab. But how about real-world applications? How can we strengthen eye-tracking technology so that it works in naturalistic scenarios, with ambient light, eyeglasses, smudges and dirt on the lenses?

Data quality

How good is your eye-tracker in terms of tracking rate but also in accuracy and precision? How can you tell? And what to do if the scenario does not allow for a more accurate recording?

Go to Visualization


Data analysis beyond the heatmap. How do we make sense out of that huge pile of data? Is is actually useful at all?
