Project A05 deals with human-robot interaction and analyzes how attention can be directed in the explanation process. The aim of the experimental investigations is to understand whether certain types of attention guidance on the micro and task level of interaction lead to different expressions of attention parametres in humans in order to implement them in the behavior of a robot in terms of scaffolding and monitoring. The investigations at the task level address the history of interaction, which is a prerequisite for the emergence of a social practice.
