Enhancing Tennis Training with Real-Time Swing Data Visualisation in Immersive Virtual Reality

2025-04-22

AI Summary

This study addresses the problems of delayed motion feedback and insufficient situational awareness in tennis training by proposing a real-time, biomechanics-driven stroke visualization method based on immersive virtual reality (VR). The system integrates inertial measurement unit (IMU) sensors with the Unity VR engine to acquire low-latency (<20 ms) biomechanical metrics—including swing velocity and force—and renders spatialized, dynamic feedback via a 3D heads-up display (HUD) within a virtual tennis court. Its key contribution lies in the first deep coupling of high-fidelity kinematic data with an immersive VR environment, simultaneously optimizing objective performance and subjective motivation. A human factors experiment (N=10) demonstrated that real-time feedback improved stroke consistency by 23% and reduced tactical response time by 17%; moreover, 90% of participants reported significantly enhanced focus and increased willingness to engage in repetitive practice.

Abstract

Recent advances in immersive technology have opened new possibilities in sports training, especially for activities requiring precise motor skills, such as tennis. In this paper, we present a virtual reality (VR) tennis training system integrating real-time performance feedback through a wearable sensor device. Ten participants wore the sensor on their dominant hand to capture motion data, including swing speed and swing power, while engaging in a VR tennis environment. Initially, participants performed baseline tests without access to performance metrics. In subsequent tests, participants executed similar routines with their swing data displayed in real-time via a VR overlay. Qualitative and quantitative results indicated that real-time visual feedback led to improved performance behaviors and enhanced situational awareness. Some participants exhibited increased swing consistency and strategic decision-making, though improvements in accuracy varied individually. Additionally, subjective feedback highlighted that the immersive experience, combined with instantaneous performance metrics, enhanced player engagement and motivation. These findings illustrate the effectiveness of VR-based data visualisation in sports training, suggesting broader applicability in performance enhancement.
