An 'embodied conversational agent' (ECA) is a fancy name for an AI avatar. It is "a digital system that supports conversational interaction with users by means of speech or other modalities" and features "computer-generated visual virtual characters capable of both empathic verbal and nonverbal communication." This survey tests for effectiveness "for mAnaging stRess at University (ARU)... ARU, a Hindi language word which literally translates to 'Beautiful like the Sun'".In particular, ARU uses explanation to address stress; "Explainable agents (XAs), particularly, belief-desire-intention (BDI) agents, have been introduced to simulate the human natural way of behaviour explanation." The study concludes, not surprisingly, that "users reported a significant reduction in their stress levels for all explanation groups."
