A Systematic Review on the Socio-affective Perception of IVAs' Multi-modal behaviour

The multimodal behaviour of IVAs may convey different socio-affective dimensions, such as emotions, personality, or social capabilities. Several research works show that factors may impact the perception of the IVA's behaviour. This paper proposes a systematic review, based on the PRISMA method, to investigate how the multimodal behaviour of IVAs is perceived with respect to socio-affective dimensions. To compare the results of different research works, a socio-emotional framework is proposed, considering the dimensions commonly employed in the studies. The conducted analysis of a wide array of studies ensures a comprehensive and transparent review, providing guidelines on the design of socio-affective IVAs.
