Editorial: Computational Approaches for Human-Human and Human-Robot Social Interactions

Non-verbal behaviors such as gaze, facial expressions, gestures, and vocal behavior carry significant information regarding human personality, emotions, engagement, intentions, action goals, and focus of attention. A large part of human communication takes place non-verbally (and often implicitly) during an explicit exchange of thoughts, attitudes, concerns, and feelings. Analyzing the basic principles of human communication through non-verbal signals is a long-standing research focus in cognitive and social psychology. However, the automatic realization of such analyses, especially by using machine learning (ML), or, in general, computational techniques, is a relatively unexplored avenue, although these techniques can be very efficient and effective.
