Outils d'évaluation du design de l'avatar dans l'engagement du joueur

Abstract : In this thesis, we produce measurement tools to characterize the design of an avatar and evaluate the player’s engagement. These are two critical points for the design of video games and serious games. Engagement is widely studied in different research fields and it is not defined yet. The feeling of presence and the desire to pursue the game are two elements of the player’s engagement. Theoretically, the feeling of responsibility is also a part of it. This sensation can be similar to the player experience. The player and the game form a dynamic system. The graphical environment is part of this system. Its semantic aspects or its consistency keeps the player engaged. On the other hand, the avatar is a dynamic object from this virtual environment of the game. Its character design has an impact on one's behaviors in virtual environments and in the video game. Some tools and methods seem effective to measure the player’s engagement, describe the player’s behaviors or characterize an avatar. But these tools and classifications are unsuitable for research studies in video games and for designers. We conducted three experiments to test the effectiveness of our methods and tools. First, we define the feeling of responsibility in video games. The results show that this feeling is a component of the player's engagement and it can be measured. We propose a method and we test our classification of video games' images. This classification can be used by designers. Its use can occur interesting theoretical analysis of images. Finally, we design a video game, Sympathy, dedicated to studies on the avatar and the player’s engagement. We conclude that avatars' design according to our classification have influenced the behavior of play.
