Abstract

The current thesis is an attempt to create intelligent virtual agents with emotion-driven behavior. Integrating emotions on virtual reality applications is necessary in order to succeed human behavior simulation, as humans’ decisions and actions are greatly affected by their emotional state. The thesis begins by presenting an overview of the computational models and theories of emotion, which were developed in order to replace traditional emotion theories, as they are suitable for computational applications. The ALMA model was selected as the most appropriate for the current implementation, so a short presentation of its basic elements follows next. In the same unit the important implementation decisions are presented, which were taken in order to cover the obscure and unpublished spots of ALMA model, and of the diverse emotional theories which compute emotions, mood and personality. The specific unit ends by presenting the emotion creation, mood change and action selection mechanism that emerged by the combination of ALMA model and the important implementation decisions taken. To continue, the implementation of the emotion creation, mood change and action selection mechanism on REVE Worlds platform is described in detail. “Graphical Display” unit presents the extensions made on REVE Worlds platform in order to support emotions, mood, personality, speech and action display. Finally, the indicative implemented scenario is presented, followed by some characteristic execution examples. The thesis comes to an end by concluding and proposing ways of improving implementation
