The appearance of a person influences the perception of his personality. People use static as well as dynamic cues to assess others. The clothes, facial expression, and posture of a person influence the viewer's perception of its personality; and the same applies to a virtual character. In this context, it would be helpful for a designer to have the tools to shape a virtual character so that its physical aspect conveys the intended personality traits to the observer. In order to run this category of experiments, our research units are building a new open-source platform called DeEvA ( To test and validate the platform, we recently conducted an experiment to detect which facial features of a virtual character drive the perception of the personality composed of five psychological constructs: dominance, trustworthiness, agreeableness, attractiveness, and narcissism. For each of the five traits separately, we ran a multivariate logit regression with the purpose to find the best predictors of a trait score from the values of the physical attributes.
