The purpose of our project is to develop a tangible sports system software framework. As a convergence of digital media contents and sports science is accelerated, it is essential to research up-to-date virtual reality and tangible sports technology. To implement our project, we design tangible sports software framework kernel, IMU sensor, vital signal sensor, pressure filtering module and realtime haptic system. Combination of add-on system and motion platform are also needed for this project. As a result of the research, a motion-estimation algorithm, upper body motion tracking system and visualization of essential coaching components are developed. With the result of our research, we expect industrialization as transferring our technology to corporations. In most cases, direct lessons or special equipments are needed to correct golfing motions. Otherwise, only fragmentary information will be collected by limited equipments. However, with only a few cameras and statistical databases, we can extract a more useful data than those from expensive equipments.

In this project, we develop the algorithm for getting joints positions and angles of user by using images form several cameras and database within the margin of error of 5 degrees.
Also, improve the performance of the algorithm in the motion analysis time into 30 sec/frame. Additional to this, we add 3 dimensional club tracking algorithm, which can provide various geometric information of golf swing by reconstructing club trajectory from image sequences. And make swing analysis more efficient by displaying theses information in 3 dimensional space with point cloud information of human from Kinect.

Virtual coaching program could be used as a wonderful assisting program to develop sport skills and train physical abilities by oneself using sports simulator, free from time and space restriction. This program could help developing one's sports performance and fitness systematically and continuously using database from laboratory experiment and broad interview. Our purpose of this project was to establish customized coaching program. This contribute to a multidisciplinary area: physical education, physical, sport biomechanics, motor control, and sport medicine.
We categorized and made a coaching protocol from literature search and interview based on questionnaire focused on golf. We found out main factors which needs to be trained specially for novice. Weight shift, cocking, tempo, stiffness are those factors. We focuse on early un-cocking and establish coaching protocol. In conclusion 3th year project was performed to establish virtual coaching protocol about golf and snowboard which would have been used on virtual reality forseeable future.
