Abstract: "Obesity has become an outstanding public health issue in most countries around the world. Many attempts have been made to address this issue that ranges from taking medication to doing exercise to follow- ing a diet plan to playing games. Few approaches combine exercise and game to engage the obese people in playing fun-based games or pur- poseful games, also known as serious games, while monitoring their bio- signals. However, existing work hardly provides a configurable, scalable and context-aware serious game framework that can be used as a sup- port for obesity treatment. In this paper, we take an attempt to propose such a framework. The proposed framework facilitates bio-signal monitor- ing based on body sensor network, context-awareness based on perva- sive sensors, and on-the-spot activity recommendation based on current game-playing context. It uses the cloud computing platform as infrastruc- tural support that ensures the scalability of the framework. In order to demonstrate the suitability of the proposed framework, we developed a sample serious game; deploy it over a cloud platform; and experiment with it by capturing some psycho-physical data while the obese are en- gaged in game-play. We observed that the obese people were very much engaged in game-play and they had positive experience using the system"

Abstract: "Adolescent obesity is an increasing challenge, and pervasive social health games hold much promise for promoting sustained healthy behaviors. Researchers and d esigners of these systems have many potential theories and existing best practices at their disposal. Our study, grounded in participatory design, shows which ones matter - both for pervasive social health games and within the cultural context of a community we studied over the course of three years. We worked with 112 US middle school students from a lower - income community in a series of participatory design exercises focused on social rewards for everyday physical activity. In our analysis, we discuss design implications in four key areas : social presence, gender effects, incentives and competition. We show how these themes manifested in students' designs and why they were particularly important to our participa nts. We then use our findings to suggest design strategies for youth - focused pervasive social health games."
