The aim of this research is to identify the main metrics linked to soccer goalkeeping that can be computed by using a small embedded device. Based on the identified KPIs, a prototype is created by using an old Android phone in order to compute them based on the values of the three sensors related to positioning: accelerometer, gyroscope and magnetometer. In the final part of this paper, the obtained results are validated in a real case scenario by comparing the values of computed KPIs against some baseline values. The baseline values are extracted from the video recording of the trainings where the goalkeepers used our wearable embedded system. By constructing a cheap and small version of our prototype, we can help small soccer teams to understand and use data to better train their goalkeepers.
