    Enjoyment, Immersion, and Attentional Focus in a Virtual Reality Exergame with Differing Visual Environments
    (The Eurographics Association, 2017) Abernathy, Michael; Shaw, Lindsay A.; Lutteroth, Christof; Buckley, Jude; Corballis, Paul M.; Wünsche, Burkhard C.; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    Virtual reality exergames provide a compelling distraction from the possible discomfort and negative perception of exercise by immersing users in three dimensional virtual worlds. Prior studies have looked at the effects of immersion in exergames, from the technologies used, to gameplay elements, to sensory stimulation. This study examines the level of immersion and distraction caused by various visual environments, including urban, rural, and desert landscapes, and the effects on users' performance, enjoyment, and motivation. The environments were found to have little effect on the user. It appears that the core gameplay elements have a far greater effect, being essential for the immersion a user experiences.

    Fast and Accurate Simulation of Gravitational Field of Irregular-shaped Bodies using Polydisperse Sphere Packings
    (The Eurographics Association, 2017) Srinivas, Abhishek; Weller, Rene; Zachmann, Gabriel; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    Currently, interest in space missions to small bodies (e.g., asteroids) is increasing, both scientifically and commercially. One of the important aspects of these missions is to test the navigation, guidance, and control algorithms. The most cost and time efficient way to do this is to simulate the missions in virtual testbeds. To do so, a physically-based simulation of the small bodies' physical properties is essential. One of the most important physical properties, especially for landing operations, is the gravitational field, which can be quite irregular, depending on the shape and mass distribution of the body. In this paper, we present a novel algorithm to simulate gravitational fields for small bodies like asteroids. The main idea is to represent the small body's mass by a polydisperse sphere packing. This allows for an easy and efficient parallelization. Our GPU-based implementation outperforms traditional methods by more than two orders of magnitude while achieving a similar accuracy.

    Tour de Tune - Auditory-game-motor Synchronisation in Exergames
    (The Eurographics Association, 2017) Finlayson, Jenna; Peterson, Jamie; Free, Joshua; Lo, Michael; Shaw, Lindsay A.; Lutteroth, Christof; Wünsche, Burkhard C.; Robert W. Lindeman and Gerd Bruder and Daisuke Iwai
    Exergaming has been heralded as a promising approach to increase physical activity in hard-to-reach populations such as sedentary young adults. By combining physical activity with entertainment, researchers and developers hope that the excitement and immersion provided by a computer game will result in increased motivation and dissociation from the discomfort of physical exercise. A different approach to improve physical activity is the use of music. Music, in particular if synchronised with the rhythm of exercise, has been shown to increase performance and decrease the amount of perceived effort for the same performance. So far little research has been done on the combined effect of music and gameplay in exergaming. In this paper we investigate the effect of game-music synchronisation for an immersive exergame. We present a simple yet effective music analysis algorithm, and a novel exergame enabling synchronisation of gameplay with the music's intensity. Our results indicate that our exergame significantly increases enjoyment and motivation compared to music alone. It slightly increases performance, but also increases perceived effort. We did not find any significant differences between gameplay synchronised and not synchronised with the music. Our results confirm the positive effects of music while exercising, but suggest that gameplay might have a bigger effect on exergame effectiveness, and more research on the interaction between gameplay and music needs to be done.
