An inertial-based system for golf assessment

This paper describes a sensor which is designed to help golf players to increase their capabilities by tuning their movements. The proposed solution is characterized by having the sensing unit to be attached to the golf club near to its head so that the sensor placement is easy and the sensor can be moved when the club is changed by the player. The sensor is able to communicate with either a smart-phone or a PC by using the bluetooth LE protocol so that there is no reason to remove the sensor from the club during its use. A GPS unit is used to track the club position so that it is also possible to recreate a golf session including the stroke positions to review the procedure. The system is arranged by using all commercial off-the-shelf components embedded into a 3D printed case. The overall cost is of less than 100$ making it an easy and simple tool for assessing and improving the player skills.
