Title: Bridging the Gulf of Uncertainty in Intelligent Interactive Systems

Abstract:
The surge in AI technologies introduces new, useful functionality to interactive systems but may also increase uncertainty for their users. While traditional interactive systems cause uncertainty for users mainly through inadequately engineered functionality and user interfaces, intelligent systems inherently introduce uncertainty by applying probabilistic methods that mostly operate within opaque black box models. Uncertainty can significantly impair the user experience and trust in the system and have harmful effects on an individual or societal level. In this talk, Jürgen will discuss technical and cognitive sources of uncertainty and how to cope with them from a user-centric perspective. Using recommender systems as an example, he will propose principles for bridging the ‘gulf of uncertainty’ in user–system interaction. Specifically, the talk will address approaches to promoting user understanding of the decision space, enabling user control and exploration, and progressing from explaining AI functions towards co-operative human-agent systems.

Jürgen is a senior full professor in the Faculty of Computer Science at the University of Duisburg-Essen where he is conducting research in the field of Intelligent Interactive Systems. His main research interests lie in the areas of human-computer interaction, human-AI cooperation, recommender systems, social media, and information visualization.
