Abstract:
Most skiers who use smartphones carry them when they ski. Lately internet connection is getting better and
there can be active information exchanges between applications installed in smartphones and online operating
servers. In addition, with the use of GPS, smart phones can precisely track skier’s locations and record the
real time information of the gyroscope sensors connected to the Bluetooth of smart devices. This study aims
to design and develop a mobile application which can monitor ski trails and analyze ski postures with the help
of smartphones technology. For this reason, our mobile application was developed based on Android SDK
4.2 version using Java, and C-language. To measure the information of the skier’s posture, a belt with several
gyroscope sensors was developed. It records the postures of the skiers who wear the belt when they move
their body from side to side and back and forth. Through the application’s calculations of the skier’s speed and
directional tur
ning track data, skiers can know what modifications they need to make in order to improve their
techniques and adjust their postures. This mobile application can exchange information with online operating
servers with the use of 3G and Wi-Fi. In addition, it operates as a background program in smartphones and
starts recording and analyzing when skiers start skiing at designated ski resorts.
