Gaze-based Interaction
Gaze-based Interaction

Humans use their gaze very early in their ontogenese to interact with others. Compared to other modalities, gaze is also very quick and very versatile. On the other hand, gaze is difficult to interpret.

In this line of research I address gaze-based human-computer interaction on different levels: to analyse attention, for direct control and for adaptive interfaces.

Mobile Cognitive Assistance Systems
Mobile Cognitive Assistance Systems

This line of research is aiming at wearable mobile assistance systems, that provide support for cognitive demanding tasks.

Joint Attention
Joint Attention

Sharing the focus of visual attention with an interlocutor on objects in the environment and at the same time sharing intentions relating to the objects: this is what we call joint attention. It is a necessary precondition for many joint actions and a way of grounding communication.

Human-Machine-Interaction
Human-Machine-Interaction

In the research area of human-machine interaction I am focussing on interaction in 3D spaces and on non-verbal modalities, such as gestures or gaze, or the interaction thereof with speech.

Multimodal Communication
Multimodal Communication

In my work on multimodal communication I am focussing on gaze and gestures in interaction with speech. The interactions I am interesting in are alwas communication scenarios between humans or humans and virtual avatars or, recently, robots.

Past Research Projects

Artificial Intelligence
Artificial Intelligence

Many of the research topics I am working on are more or less related to the topic of artificial intelligence. The most prominent examples are Mobile Cognitive Assistance Systems or Joint Attention with virtual agents. However, there are also some projects, such as the virtual agent Max himself or work on math text problems, that are primarily located in this field of research.

Technically Mediated Communication
Technically Mediated Communication

Communicating within and between virtual environments using speech and gestures. Augmenting mediated communication with physiological and emotional data.

PASIONPASION - Psychologically Augmented Social Interaction Over Networks

The PASION project addressed questions on how telemediated communication could be improved, e.g. via augmentation, to improve social networking of the participants.

Social Networks
Social Networks

Online social networks are an interesting research topic from a user interaction perspective. While most approaches addressing the user interface of such communities are targeting at optimizing the user experience of the individual, I am more interested in revealing the richness of the data that is collected and hosted in such communities to the individual.
