This is despite the fact that many application scenarios for future ECAs involve the presence of others. This paper critiques the view of an ‘isolated user’ and proposes a micro-sociological perspective on the participation roles in HAI. Two examples of an HAI in a public setting point out (1) the ways a variety of participants take part in the interaction, (2) how the construction of the participation roles influences the construction of the agent’s identity, and (3) how HAI, as a mediated interaction, is framed by an asymmetric participation framework. The paper concludes by suggesting various participation roles, which may inform development of ECAs. %G English %Z TC 13 %2 https://inria.hal.science/hal-01610810/document %2 https://inria.hal.science/hal-01610810/file/346948_1_En_19_Chapter.pdf %L hal-01610810 %U https://inria.hal.science/hal-01610810 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC13 %~ IFIP-INTERACT %~ IFIP-LNCS-9299
