US 2025/0180674 A1 · WEARABLE ELECTRONIC DEVICE COMPRISING MAGNETIC STRAP AND METHOD FOR UPDATING GEOMAGNETIC DATA

Abstract

A wearable electronic device including a magnetic strap is provided. The wearable electronic device includes a communication module, a geomagnetic sensor, a motion sensor, memory storing one or more computer programs, and one or more processors communicatively coupled to the communication module, the geomagnetic sensor, the motion sensor, and the memory, wherein one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the wearable electronic device collect geomagnetic measurement values collected using the geomagnetic sensor, determine whether to update a reference magnetic field stored in the memory on the basis of offset update information of the geomagnetic sensor, when updating the reference magnetic field, designate, as reference data, geomagnetic measurement values satisfying a first condition collected within the effective time of the reference magnetic field, a second condition for collecting of magnetic field strengths within an average error range, and a third condition collected within a movement range through the motion sensor, and update the reference magnetic field based on the designated reference data.
