Sensor-based technologies (SBTs) allow users to track biometric data and feature interactions that foster social support. The social support from SBTs can increase intrinsic motivation to engage in and sustain positive health behaviors. Guided by technological affordances and self-determination theory, this study tested the long-term efficacy of an ecosystem of SBTs to strengthen social support for children's behavior change, children's perceived relatedness, and positive physical activity (PA) attitudes. This ecosystem integrated Fitbits tracking each child's PA, kiosks with virtual agents that synced with Fitbit data, and a messaging system for parents and children. Afterschool programs ( = 19) were randomly set with this ecosystem or a Fitbit with a computer for 6 months. Results suggested that parents of girls provided more social support to children via the ecosystem than parents of boys. Children's perceived support from the virtual agent was positively associated with perceived relatedness and PA attitudes over time.
基于传感器的技术（SBTs）使用户能够追踪生物特征数据以及促进社会支持的特征交互。来自SBTs的社会支持可以增强参与并维持积极健康行为的内在动力。本研究以技术可供性和自我决定理论为指导，测试了一个SBTs生态系统在加强对儿童行为改变的社会支持、儿童感知到的关联性以及积极的体育活动（PA）态度方面的长期效果。这个生态系统整合了追踪每个孩子体育活动的Fitbit、与Fitbit数据同步的带有虚拟代理的信息亭，以及一个供家长和孩子使用的信息系统。19个课后项目被随机设置为使用这个生态系统或配备电脑的Fitbit，为期6个月。结果表明，与男孩的家长相比，女孩的家长通过该生态系统为孩子提供了更多的社会支持。随着时间的推移，孩子们从虚拟代理那里感知到的支持与感知到的关联性和体育活动态度呈正相关。
