Recent developments in social signal processing

Social signal processing has the ambitious goal
of bridging the social intelligence gap between computers and
humans. Nowadays, computers are not only the new interaction
partners of humans, but also a privileged interaction medium for
social exchange between humans. Consequently, enhancing machine
abilities to interpret and reproduce social signals is a crucial
requirement for improving computer-mediated communication
and interaction. Furthermore, automated analysis of such signals
creates a host of new applications and improvements to existing
applications. The study of social signals benefits a wide range
of domains, including human-computer interaction, interaction
design, entertainment technology, ambient intelligence, healthcare,
and psychology. This paper briefly introduces the field and
surveys its latest developments.
