Anticipation

Although different aspects of believability have been researched, all work supports the basic principle that motion cannot be devoid of meaning and considers the issue of variability over a consistent core to be of importance to manage the expectations of the viewer, provide the illusion of life and allow for the audience suspension of disbelief. This is particularly important as it stresses the importance of both anticipation and character personality in the creation of believable behaviour. By making personality-based anticipated outcomes the very core of the decision making process, expression can take into account this same outcome to provide a whole coherent behaviour for the character, one that provides meaning to action by disclosing the inner mental process and strengthens the illusion of life.

Explicit representations of the future state of the world (i.e. not relying solely of past and present information) has been shown to allow the creation of synthetic behaviour perceived as more believable. We expect this be of importance when considering a scenario in which several agents and users are interacting together. As such, we argue that autonomous agents in social situations should consider predictions about the goals and plans of others in order to be perceived as believable. We state that because social identity and personality are central factors of decision in social situations they are consequently pivotal elements of behaviour predictive models.
