“Making Robots More Acceptable” – the words of Professor Gordon Chen who leads ICS (Institute for Cognitive System) at TUM. What exactly is a robot that does not give discomfort to us and we can easily accept its existence as a part of everyday life? Now we obtain capabilities to access ubiquitous information spaces and our human ability and cognitive performance will be gradually enhanced. Robots will also be integrated well into the human life and helping us naturally. They will have rich sensory perception and expressive facial signals, and are going to be social partners for us. In this tutorial, we are discussing what kind of “sociality” robots should have in human robot interactions (HRI).
