Investigation of dependencies between virtual 3D face stimuli and emotion-based human responses

Abstract

Virtual environment is an important part of everyday life, as lots of children and adults engage themselves in social networks, internet applications as well as computer games. The influence that is done to the person through those activities in the virtual environment is important for their daily life and psycho-emotional state. In the paper, the dependencies between the features of virtual dynamic object (3D virtual face) as stimulus and corresponding human psycho-emotional state parameters (engagement/boredom, excitement, and frustration) are modeled. Model validation shows that output signals can be predicted when using least squares method for unknown parameter estimation
