Abstract
With the increasing of computers in the daily life of everyone highlights the relationships we develop with them and the importance of these relationships. In order to provide synthetic characters with relationships, it is important to use the psycho-sociological background of the human relationships and strategies used by humans to create and manage those relationships. We have developed a model of relationships that uses the processes involved in these relationships in several dimensions. For this purpose we have based our research in both computational systems that include relationships and in theoretical theories of the psycho-sociology of human relationships. In this way, our model was constructed according to the three main concepts identified in our research: stages: fixed set of levels that different relationships go through; filters: sequence of decisions where we make a choice to maintain or exclude someone from the relationship; strategies: the evolution of a relationship is not a static process but a consequence of interactions by someone and the perception and validation of that interaction by the other relationship partner. As a way to validate and test our model, we have introduced the intimacy relationship and conducted an experiment with eight users where they interacted with a prototype of a game where they to develop a relationship with one character. The evaluation of the experiment results showed that, from all the test conditions, the one that included our model presented the better results, for all the three variables of measure, in the relationship establishment.
