This paper addresses the issue of whether robots could substitute for human care, given the challenges in aged care induced by the demographic change. The use of robots to provide emotional care has raised ethical concerns, e.g., that people may be deceived and deprived of dignity. In this paper it is argued that these concerns might be mitigated and that it may be sufficient for robots to take part in caring when they behave *as if* they care.

Communication is not just about the transfer of verbal information. Gestures, facial expressions, intonation and body language are all major sources of information during conversation. This book presents a new perspective on communication, one that will help us to better understand humans, and also to build machines that can communicate.
