Avatars are becoming the central interface of the metaverse. This book explains how they function as digital identities, enable communication beyond screens and keyboards, and thereby reshape work, education, and social interaction.
It explores the psychological impact of virtual self-representation and the tensions between the real and the digital self, while presenting the foundations of avatar-based interaction as well as nonverbal and emotional communication in immersive environments. From a technological perspective, it examines AI-driven personalization, motion tracking, haptics and body language, as well as blockchain and NFTs for user-owned digital identities.
A particular focus is placed on the concept of A3 - autonomously acting avatars: from reference architectures and real-time avatars to D2A3 applications in commerce, learning, work, and entertainment. The book is rounded off with a discussion of legal and ethical issues--including digital rights, data privacy, and manipulation--and concludes with an outlook on AR/VR technologies and AI assistants that will further blur the boundaries between the physical and digital worlds.
