Systems and methods for formulating performance metric of motion of swimmer

Abstract

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.

Description

technical field [0001] The present invention relates to systems and methods for formulating performance metrics of a user's movements, particularly for applications to aquatics, especially swimming. The present invention includes wearable devices and associated software for collectively monitoring gesture techniques. Although some embodiments will be described herein with particular reference to this application, it should be understood that the invention is not limited to such fields of use, and is applicable in a wider context. Background technique [0002] Throughout the specification, any discussion of background art is not to be considered in any way as an admission that such art is well known or forms part of the common general knowledge in the field. [0003] Among professional athletes, wearable accessories for monitoring athletic performance are well known and common. More recently, the advent of lower-cost wearable devices for monitoring athletic performance has ...

AI Technical Summary

Problems solved by technology

While most coaches can visually identify a swimmer's errors regarding technique (which is time-consuming and laborious and only provides qualitative feedback on gross errors), more subtle technique errors can be more difficult to identify and require some of the aforementioned facilities

These devices are rarely used by coaches, not only because they are bulky and expensive, but also because they often require biomechanical experts to analyze and interpret the captured data
