摘要
A system for formulating a performance metric of a motion such as water sport motion, preferable a swimming stroke, includes a wearable sensor device including 4 pressure sensors, a 9 degrees of freedom inertial measurement unit (IMU), a microprocessor communicating with the pressure sensors and the IMU, and waterproof housing in the form of a flexible silicone band to house the microprocessor, the pressure sensors and the IMU. The system includes an external computer communicating with the device for receiving and combining input data from each of the pressure sensors and the IMU, via the microprocessor, and a processing unit configured to combine the input data from both the at least one pressure sensor and the IMU. The input data is used to infer at least one force magnitude and at least one force direction, the input data being used to provide the performance metric of the water sport motion.
