Needs and challenges in human computer interaction for processing social emotional information

Demand for and delivery so far of sophisticated computational instruments able to recognize, process and store relevant interactional signals, as well as interact with people, displaying suitable autonomous reactions appropriately sensitive to environmental changes, have produced great expectations in Information Communication Technology (ICT). Knowing what an appropriate continuation of an interaction is depends on detecting the addresser's register and a machine interface unable to assess differences will have difficulty managing interactions. Progress toward understanding and modeling such facets is crucial for implementing behaving Human Computer Interaction (HCI) systems that will simplify user access to future, profitable, remote and nearby social services. This paper raises new research questions via new means for socio‐behavioral and emotional investigations, and suggests the gathering of new experimental data and theories across a spectrum of research concepts, in order to develop new psychological and computational approaches crucial for implementing believable and trustable HCI systems which exploit synthetic agents, robots, and sophisticated humanlike interfaces.
