Abstract
Low motivation and fragmented digital tools often limit the sustainability of community physical activity programs. To address this, the authors developed a virtual health information system that integrates wearable sensing devices, immersive interaction, and group incentives within a multimodal data-based closed loop. A stratified randomized controlled trial showed significant improvements in physical activity levels, behavioral adherence, and well-being in the intervention group. A causal analysis revealed heterogeneous effects by age and health status that can inform a tailored strategy of stratified goals, time-based rewards, and community co-creation. Qualitative feedback highlighted the role of transparent feedback and collective identity in sustaining engagement. This study demonstrates how an integrated virtual health system can support scalable, community-driven public health interventions.Article Preview

In recent years, digital health technology—driven by the widespread application of wearable sensing technology, immersive XR, and social metaverse scenarios—has emerged as a pivotal driving force for facilitating public physical activity participation (Kim et al., 2023; Saklani & Avnish, 2023). Three major developmental trajectories have been formed in global relevant research.
