Interactive storytelling is a form of digital entertainment in which users participate in the process of composing and dramatizing a story. In this context, determining the characters behaviour according to their individual preferences can be an interesting way of generating plausible stories where the characters act in a believable manner. Diversity of stories and opportunities for interaction are key requirements to be considered when designing such applications. This thesis proposes the creation of an architecture and a prototype for the generation and dramatization of interactive nondeterministic plots, using a model of emotions that not only serves to guide the actions of the characters presented by the plan generation algorithm, but also influences the participation of the users. Also, to improve the quality and diversity level of the stories, characters must be able to evolve in terms of their personality traits as the plot unfolds, as a reflection of the events they perform or are exposed to.
