Controller for determining swimming characteristics of swimmer and method thereof

A controller 110 of a wearable device 100 is used to determine a swimming characteristic of a swimmer. The controller 110 is connected to at least one motion sensor 120 selected from the group comprising a multi-axis gyroscope 112 and a multi-axis accelerometer 114. The controller 110 is adapted to detect an input signal 202 from the at least one motion sensor 120, characterized in that the controller 110 is further adapted to perform a dynamic swipe segmentation based on the at least one input signal 202 using a swipe segmentation module 102, extract a feature vector from the at least one input signal 202 using a feature extraction module 104 based on the swipe segmentation, and determining, by a classifier module 106, a swimming characteristic by using the feature vector. A controller 110 and method is provided that dynamically adapts to the style of a swimmer to detect swimming characteristics. 可穿戴设备100的控制器110用于确定游泳者的游泳特性。控制器110连接到从包括多轴陀螺仪112和多轴加速度计114的组中选择的至少一个运动传感器120。控制器110适于检测来自至少一个运动传感器120的输入信号202，其特征
