Abstract

Continuous and synchronized whole-body motions are essential for achieving believable autonomous virtual humans in interactive applications.We present a new motion control architecture based on generic controllers that can be hierarchically interconnected and reused in real-time. The hierarchical organization implies that leaf controllers are motion generators while the other nodes are connectors, performing operations such as interpolation, blending, and precise scheduling of children controllers.We also describe how the system can correctly handle the synchronization of gestures with speech in order to achieve believable conversational characters. For that purpose, different types of controllers implement a generic model of the different phases of a gesture.
