Intelligent sports interactive monitoring system based on self-driven sensing-augmented reality fusion

Abstract

The integration of augmented reality (AR) technology with sports science delivers innovative solutions for monitoring adolescent health and enhancing exercise participation. This study introduces an intelligent sports interactive monitoring system that utilizes triboelectric nanogenerator (TENG) technology, combining real-time motion tracking with AR-driven interactivity to achieve fitness objectives through gamified training. The system features four key components: TENG-based motion-sensing modules with Ecoflex/polytetrafluoroethylene triboelectric layers on 3D-printed polylactic acid substrates embedded in shoe soles and simulated gun barrels, wireless data transmitters, a cloud analytics platform, and an AR user interface. Foot-mounted sensors identify biomechanical differences between running speeds like jogging and sprinting, while gait analysis algorithms automatically compute step totals and calorie expenditure. Simultaneously, firearm-mounted sensors capture trigger actions to coordinate virtual shooting sequences, integrating foot movement data for full-body avatar control in AR environments. This dual-input design enables users to navigate virtual challenges through coordinated physical maneuvers, transforming routine exercises into narrative-driven missions. The framework establishes a scalable model for advancing youth fitness initiatives through adaptive difficulty settings and performance-based virtual rewards. By merging wearable motion capture with immersive digital interactions, the system pioneer applications for AR in sports training methodologies while addressing critical needs in adolescent health management. This technological synergy demonstrates how extended reality solutions can bridge physical activity with digital engagement, offering actionable insight for the next-generation sports science innovation.
