Embodied Conversational Agent (ECA)

具身对话代理：能通过语音、姿态、眼神、表情等多模态通道与用户交互的虚拟代理，可营造较强的社会临场感。

English Definition

"A conversational agent that uses multiple embodied communication channels (voice, gesture, gaze, facial expression) to interact with users, creating a sense of social presence."

用法说明 · 针对中文母语者

区别于纯文本 chatbot；VR 中的 NPC、虚拟助手多属于 ECA。

常见错误

·不要和 chatbot 混用——chatbot 通常仅指纯文本界面
·不要省略 embodied，单独说 conversational agent 一般指非具身系统
