Abstract
We aim at analyzing human throwing motion with a sensor ball. So far, we developed the first prototype, which consists of a 9 axis motion sensor, a microchip computer, a data storage, a rechargeable battery, and, a set of plastic hemispherical cases. We also conducted a ball throwing experiment for the performance test. As results, we confirmed that the frequency analysis illustrated 4 motion states: loading, lifting, releasing, flying, and catching.
