| Popis: | The goal of this paper is to evaluate the human perception regarding geometric features, personalities and emotions in avatars. To achieve this, we used a dataset that contains pedestrian tracking files captured in spontaneous videos which are visualized as identical virtual human beings. The main objective is to focus on individuals motion, not having the distraction of other features. In addition to tracking files containing pedestrian positions, the dataset also contains emotion and personality data for each pedestrian, detected through computer vision and pattern recognition techniques. We are interested in evaluating whether participants can perceive geometric features such as density levels, distances, angular variations and speeds, as well as cultural features (emotions and personality traits) in short video sequences (scenes), when pedestrians are represented by avatars. With this aim in mind, we propose two questions to be answered through this analysis: i) “Can people perceive geometric features in avatars?"; and ii) “Can people perceive differences regarding personalities and emotions in virtual humans without body and facial expressions?". Regarding the participants, 73 people volunteered for the experiment in order to answer the two mentioned questions. Results indicate that, even without explaining to the participants the concepts of cultural features and how they were calculated (considering the geometric features), in most cases the participants perceived the personality and emotion expressed by avatars, even without faces and body expressions. |
