Researchers have created mixed-reality humans (MRHs) and applied them to critical team training. MRHs are embodied conversational agents with virtual and physical components that inhabit the user's space. In this research, MRHs role-played members of an operating-room team. Studies examined how MRH components affected social presence (the user's sense of "being there" with an embodied conversational agent) and the training of communication skills for medical teams.
