ABSTRACT
The purpose of this study is to develop a Skier Training System for monitoring skiing courses and analyzing
skier posture using smartphones. The system is composed of three elements: first, operating servers that
receive information on the skier’s exercise; second, Skier Training Apps developed using Java and C based
on Android SDK 4.2 or above; and third, Data Gathering Gear embedded with gyroscope sensors and GPS
for measuring skier stance. When a skier wearing our Data Gathering Gear runs down a slope, his or her
stance is uploaded to the operating servers. Then the servers calculate the recorded data, such as velocity
and turn trajectory, in order to suggest body angles that are optimized for the skier; subsequently, the skier
can improve his or her skills by checking his or her records, and then attempt to correct his or stances
based on the suggestions offered by the Skier Training Apps.
