Wearable device, electronic watch, magnetic sensor calibration method, and recording medium

A magnetic sensor calibration method for performing a magnetic sensor calibration of a magnetic sensor of a wearable device, the magnetic sensor calibration method comprising:

• selectively executing one of a plurality of function modes comprising a first function mode and a second function mode;
• determining whether a calibratable state exists, the calibratable state being a state in which a movement state of the wearable device sensed meets a predetermined condition indicating that the magnetic sensor is calibratable;
• determining which function mode of the plurality of function modes is being executed;
• performing the magnetic sensor calibration in response to the function mode being executed being the first function mode and determining that the calibratable state exists;
• and
• not performing the magnetic sensor calibration in response to the function mode that is being executed being the second function mode or determining the calibratable state does not exist.

A non-transitory computer-readable recording medium recording a program for performing a magnetic sensor calibration, wherein the program causes a computer of a wearable device to at least perform:

• selectively executing one of a plurality of function modes comprising a first function mode and a second function mode;
• determining whether a calibratable state exists, the calibratable state being a state in which a movement state of the wearable device sensed meets a predetermined condition indicating that the magnetic sensor is calibratable;
• determing which function mode of the plurality of function modes is being executed;
• performing the magnetic sensor calibration in response to the function mode being executed being the first function mode and determining that the calibratable state exists;
• and
• not performing the magnetic sensor calibration in response to the function mode that is being executed being the second function mode or determining the calibratable state does not exist.
