In situ sports performance analysis system using inertial measurement units, high-FPS video camera, and the Android platform

Abstract

We developed a mobile sports performance monitoring system that incorporates the use of inertial measurement units or IMUs, a high-fps video camera, and an Android tablet to provide quantitative and visual assistance to coaches and athletes in the actual location of respective sports. An Android app was developed to wirelessly communicate via Bluetooth and Wi-Fi to control the IMUs and video camera in recording high frame rate video and motion data. The app then graphically presents the motion data along with their corresponding frames from the video. With the system, coaches and athletes can easily analyze sports performances, decide the necessary courses of action to improve on them, and easily share the data in a group for peer discussions and consultations.
