DESCRIPTION (provided by applicant): Youth are not meeting PA (physical activity) guidelines, which increases their risk of obesity and related diseases such as type 2 diabetes. Therefore, it is crucial to identify methods to encourage youth to be more physically active. Virtual reality has been successfully proven to be effective at promoting desired behaviors. Youth enjoy video games, and players appear to identify with avatars, particularly those that are self-representative. Thus, design of youth-oriented immersive games where the player's live body actions can control the fate of the avatar in a virtual world may provide a promising method for increasing PA among this group at risk for low levels of PA. The research proposed in this application represents an early step in this line of research. It will create an immersive, interactive virtual reality game where the player's movements influence the fate of the avatar. Specifically, this research will work with youth to develop an immersive virtual reality game to be played via natural human computer interfaces, develop a system for creating highly self- representational avatars, develop an algorithm to unobtrusively measure PA during game-play, and conduct a pilot study to assess the feasibility of these components. If proven to be feasible, this research will provide the basis for an R01 application to assess the efficacy of this approach at increasing PA among a large number of youth in various real-world settings.

描述（由申请人提供）：青少年没有达到 PA（体力活动）指南，这增加了他们患肥胖症和 2 型糖尿病等相关疾病的风险。因此，找到鼓励青少年加强体育锻炼的方法至关重要。虚拟现实已被成功证明可以有效促进期望的行为。年轻人喜欢电子游戏，玩家似乎认同化身，尤其是那些具有自我代表性的化身。因此，设计面向青少年的沉浸式游戏，其中玩家的实时身体动作可以控制虚拟世界中化身的命运，这可能为提高这一低水平 PA 风险群体的 PA 提供一种有前景的方法。本申请中提出的研究代表了该研究领域的早期一步。它将创建一款身临其境的交互式虚拟现实游戏，玩家的动作会影响化身的命运。具体来说，这项研究将与年轻人合作​​开发一款身临其境的虚拟现实游戏 通过自然人机界面进行游戏，开发一个用于创建高度自我表征化身的系统，开发一种在游戏过程中不引人注目地测量 PA 的算法，并进行试点研究以评估这些组件的可行性。如果被证明可行，这项研究将为 R01 应用提供基础，以评估该方法的功效 旨在提高各种现实世界环境中大量青少年的 PA。
