ELECTRONIC DEVICE FOR CALIBRATING GEOMAGNETIC SENSOR, AND METHOD OF OPERATING ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18460082 titled 'ELECTRONIC DEVICE FOR CALIBRATING GEOMAGNETIC SENSOR, AND METHOD OF OPERATING ELECTRONIC DEVICE
Simplified Explanation
The patent application describes an electronic device that includes a geomagnetic sensor and a motion sensor. The device also has a processor that determines whether to calibrate the geomagnetic sensor based on a signal measured by the sensor. If calibration is needed, the processor identifies the user's motion using data from the motion sensor. Based on the user's motion, the processor determines a parameter that specifies the range of data to be used for calibrating the geomagnetic sensor. The geomagnetic sensor is then calibrated using data extracted based on this parameter.

Original Abstract Submitted
An electronic device may include: a geomagnetic sensor; a motion sensor for sensing a signal associated with a motion of a user; and a processor operatively connected, directly or indirectly, to the geomagnetic sensor and the motion sensor, wherein the processor determines whether to perform calibration of the geomagnetic sensor based on a signal measured by the geomagnetic sensor; in response to the determination to perform the calibration, identifies the motion of the user based on motion data obtained from the motion sensor; based on the identified motion of the user, determines a parameter including a range of data to be used for calibrating the geomagnetic sensor among data obtained from the geomagnetic sensor; and calibrates the geomagnetic sensor based on data extracted based on the parameter. Other various embodiments are possible.
