We want to develop an embodied conversational agent that is regarded as a social partner, not just multimodal interface. However, the mental stance of people when they interact with agents is usually different from when they interact with humans. Therefore, in some cases, it is difficult for people to speculate on an agent's emotions and for an agent to persuade people. This is a problem to solve for realizing affective communication with agents.
We take two approaches toward the problem: first, we obtain and analyze human behavior in discussion to find factors which influence humans' affective experiences using a method named Synthetic evidential study (SES for short), and second, we try to induce a positive mental stance of humans by agents' nonverbal behavior in a game situation. In this communication, we introduce two feasibility studies of them. [1] Nishida, T. et al. 2014a.
