设计和实施真正自主的身体活动（PA）干预措施需要大量的劳动力和费用，直到最近，大规模实施该领域的成本仍然高昂。在自我决定理论的指导下，利用消费级交互技术的力量，我们开发了虚拟健身伙伴（VFB）生态系统。该生态系统旨在培养 6 至 10 岁儿童采用 PA 改变生活方式的内在动力，设有一个混合现实信息亭，为每个用户容纳一只个性化的虚拟宠物。每次孩子访问自助服务终端时，宠物（中型狗）都会根据孩子 Fitbit 的数据自动检测主人，帮助孩子设定每日 PA 目标，并提供有关孩子 PA 进度的定制反馈。宠物通过发送短信并将父母的反应转发给孩子来实时提醒父母，这样父母和孩子即使在身体上分开也可以保持联系，了解孩子的 PA 进展情况。我们的目标是在 12 个课外地点实施该信息亭，并使用另外 12 个地点作为控制，孩子们仍然可以在其中设置和查看 PA 目标的进度，而无需接触虚拟宠物。 VFB 生态系统代表了新一代以技术为媒介的儿童健康干预措施，旨在促进可持续的 PA 生活方式改变。由于 VFB 生态系统是一种具有成本效益和劳动力效益的解决方案，它将消费级技术与持续使用的低门槛相结合，因此它具有快速传播和广泛的公共健康影响的潜力。
Designing and implementing a truly self-determined physical activity (PA) intervention has required excessive amounts of labor and expenses that, until recently, have made it prohibitively costly to implement in the field at scale. Guided by self-determination theory, and harnessing the power of consumer-grade interactive technologies, we developed the Virtual Fitness Buddy (VFB) Ecosystem. Designed to foster intrinsic motivation toward adopting PA as a lifestyle change in 6–10-year-old children, the Ecosystem features a mixed-reality kiosk which houses a personalized virtual pet for each user. Each time a child visits the kiosk, the pet (a mid-sized dog) automatically detects its owner based on the data from a child’s Fitbit, assists the child in setting daily PA goals and provides tailored feedback on the child’s PA progress. The pet alerts parents in real-time by sending text messages and relaying the parents’ response to the child, so that parents and children can remain connected about the child’s PA progress even when they are physically apart. We aim to implement the kiosk in 12 afterschool sites, plus use 12 additional sites as controls, where children can still set and view progress toward their PA goals without access to a virtual pet. The VFB Ecosystem represents a new generation of technology-mediated health interventions for children to promote sustainable PA lifestyle changes. Because the VFB Ecosystem is a cost- and labor-effective solution that integrates consumer-grade technology with low barriers for continued use, it has the potential for rapid diffusion and widespread public health impact.
