A Virtual Training System Based on Computer Sensing and Football Kicking Dynamics Using Real-Time Wireless Feedback

摘要

Most football simulators available use computer simulation to mimic football motion in a virtual environment. These kinds of simulations, while fun and interactive, are primarily for entertainment rather than as a training tool. In this paper, we present a virtual training system for football kicking based on computer sensing and football impact dynamics using real-time wireless feedback. It is designed as a computer-assisted training system that will give a kicker the ability to practice off the field and receive the detailed feedback comparable yet more quantitative than they would experience at a training camp. In addition, it enables football coaches with quantitative data to design player-specific training program for kickers in order to achieve a goal with more precision. The system includes a force-sensing panel to determine the position and velocity as initial data, realtime wireless feedback to calibrate the football kicking dynamics model, and an advanced visualization environment designed to recreate the realistic atmosphere of all major football stadiums. The system has been designed and tested in a lab environment. The preliminary results show that the wireless signal is sensitive enough to detect football positions on the fly. The data collected in real-time can be used to calibrate the football dynamics model in predicting the final position of the football with respect to the field goal, which is visualized using 3D stereoscopic technology.
