Electronic device and method for acquiring calibration information to be applied to sensor data of geomagnetic sensor

A method of an electronic device including a geomagnetic sensor and a gyro sensor, comprising:

• determining whether to change calibration information to be applied to sensor data of the geomagnetic sensor;
• based on a determination to change the calibration information, identifying a state of the geomagnetic sensor and a state of the gyro sensor;
• based on identifying that the state of the geomagnetic sensor corresponds to an activated state and identifying that the state of the gyro sensor corresponds to a deactivated state, changing the calibration information at a first time point by using distribution of directions of a magnetic field, which are measured by the geomagnetic sensor at a second time point that is prior to the first time point;
• based on identifying that the state of the geomagnetic sensor corresponds to the activated state and identifying that the gyro sensor corresponds to the activated state, changing the calibration information by using the directions of the magnetic field and by using a rotation angle of the electronic device, which is measured by the gyro sensor at the second time point.
