Virtual Humans: Core Believability Factors

This lecture explores the core factors that contribute to the believability of virtual humans, focusing on the importance of animation, interaction, and the integration of hidden operators in real-time constraints. It delves into the significance of minimal background animations, eye blinking, head movements, and balance swaying to enhance the realism of virtual characters. Additionally, it discusses the necessity of coherent animation with user interaction, plausible speech understanding, and gestures. The lecture also highlights the combination of virtual humans with tangible interfaces for enhanced user experience, as well as the ongoing research and development efforts in the field of real-time autonomous virtual humans by various academic and industrial groups.
