Postures and Locomotion in Mixed Reality Agents: Effects on Social Perception of Virtual Opponents and Assistants

Published in International Journal of Human–Computer Interaction, 2025

This work combines EEG with subjective and behavioral measures to examine how MiRAs’ non-verbal cues influence users’ social perceptions when the agent acts as an opponent versus an assistant.
