Abstract

Our experiment was conducted with a three -person group discussion with two participants and one digital agent, and a 2 2 within-subject study manipulating the engagement and affective posture of a digital agent. Our findings indicate. that during group discussions. the engagement posture of digital agents positively affected user perception of digital agents, whereas their affective posture negatively affected user perception.
