Virtual Humans’ Behaviour: Individuals, Groups, and Crowds

In this chapter, we first try to identify which mechanisms should be simulated in order to implement truly virtual humans or actors. We start from a structure linking perception, emotion, behavior, and action. Then we emphasize the central concept of autonomy and introduce the concept of Levels of Autonomy. Finally, we propose a new abstraction for specification of behaviours in complex virtual environment simulations involving human agents, groups of agents, and interactive objects endowed with different levels of autonomy.
