Communicating with Avatar Bodies

Explore the fascinating world of communicating with avatar bodies, delving into gestures, postures, facial expressions, and more. Learn how user movements translate onto avatars and the significance of synchrony and expression in nonverbal behaviors. Discover the design space and network issues in avatar communication, evaluating factors like task dependence and interaction engagement. Uncover the co-expressive nature of gestures and speech, and the use of virtual prototypes for design. Embark on a journey beyond chat to understand the nuanced language of avatar bodies in digital realms.
