Title: REVERIE: An ensemble-based VR sports system employing deep reinforcement learning to combat adolescent obesity

Abstract: Adolescents who are overweight can enhance not just their physical condition but also their mental well-being by engaging in physical activity. Nevertheless, they often encounter numerous obstacles, such as a lack of motivation and skill, low self-esteem, and negative peer pressure. In our investigation, we have developed a cutting-edge virtual reality (VR) sports system tailored for adolescents, known as REVERIE. This system incorporates deep reinforcement learning and is focused on guidance, providing a virtual sports experience. REVERIE comprises three key components: a VR sports environment, VR sports guidance, and VR sports visualization. To ensure a safe VR sports environment, we employ an iterative human-in-the-loop optimization process. We introduce a two-stage, template-and-feedback-based deep reinforcement learning method. In the template stage, the artificial virtual agent acquires fine-grained sports techniques, while in the feedback stage, it is personalized for each participant. To enrich the VR sports visualization, we integrate a sports-oriented immersion enhancement module into REVERIE. Quantitative results demonstrate that REVERIE surpasses current methods, offering superior safety and user experience. This research underscores the potential of VR sports as an innovative sports management approach that benefits overweight adolescents.
