<p>A device 20 and method for monitoring a swimming performance, the device comprising a motion sensor 22 which may be an accelerometer or magnetometer. The device includes a computing unit 24 that calculates a plurality of correlation factors depicting correlation of motion data between successive body motions and stores the correlation factors as a time series. The device uses the correlation data to determine information about the swim which may include the stroke count, swimming style and resting periods. The device may have a display 28 to show statistics to the user. The processor may calculate the lap count and time by determining when each turn is made at the end of a length. There may be a teaching mode to train the device to recognise the sensor data associated with different strokes such as front crawl or butterfly. This can be used to automatically identify the stroke of a swimmer. The device may be mounted on a wristband 21.</p> |
