In recent years, a smart phone which has highly efficient processor and a large number of sensors is gaining popularity. Since the smart phone is so small, it is convenient to carry, and many sport supporting systems have been developed using smartphone sensors. However, they are so simple that for example, a running support system calculates mileage, pace and records a route, and a pedometer records the number of steps. In this research, we propose sport support system using an Apple iPhone which analyzes movement data from accelerator, and gives with real time audio feedback.
