Devices and methods for configuring a wearable device for exercise tracking

A method for configuring a wearable device for exercise tracking, comprising:

• receiving sensor data generated by a sensor arrangement in the wearable device based on sensed movement of the wearable device;
• determining, by running a movement tracker model on the sensor data, a first exercise activity and an associated first confidence indicator;
• obtaining optical movement data from an image-based monitoring system detecting representations of an individual, concurrently with the sensor arrangement obtaining the sensor data;
• determining, by running an optical tracker model on the optical movement data, a second exercise activity and an associated second confidence indicator;
• processing the movement tracker model based on the first confidence indicator and the second confidence indicator.

A wearable device for exercise tracking, comprising:

• a sensor arrangement configured to generate sensor data based on sensed movement of the wearable device;
• a data storage unit for storing the sensor data and a movement tracker model;
• a wireless transceiver unit;
• and
• a processing unit configured to execute the movement tracker model on the sensor data to determine an exercise activity;
• wherein the processing unit is further configured to control the wireless transceiver unit to:
• transmit the movement tracker model to an apparatus for configuring the wearable device for exercise tracking;
• transmit the sensor data to the apparatus;
• receive processed movement tracker model data from the apparatus based on optical movement data from an image-based monitoring system detecting representations of an individual concurrently with the sensor arrangement obtaining the sensor data;
• and
• wherein the processing unit is configured to:
• update the movement tracker model on the in the data storage unit based on the processed movement tracker model data.
