Abstract
A method of calibrating a wearable electronic device including a location data unit and an inertial motion unit includes providing a calibration table including default calibration data for the wearable electronic device and determining if location data is available from the location data unit. The method also includes determining if the calibration table has been updated to achieve predetermined thresholds and receiving, from the location data unit, location data associated with the wearable electronic device as a function of time if the location data is available. The method further includes computing a travel speed of the user based on the location data if the location data is available, receiving, from the inertial motion unit, user stride data as a function of time, updating the calibration table using the travel speed and the user stride data, and providing data from the updated calibration table to the user.
