Electronic apparatus control method performed through lid angle calculation, electronic apparatus thereof and software product

A device, comprising:

• a first hardware element including a first magnetometer;
• a second hardware element including a second magnetometer, the first magnetometer and the second magnetometer configured to generate first signals indicating measurements of a magnetic field;
• and
• a processing unit configured to:
• determine a calibration parameter based on the first signals, the calibration parameter indicating a condition of calibration of the first and second magnetometers;
• determine a reliability value based on the first signals, the reliability value indicating of a condition of reliability of the first signals;
• determine a first value of a lid angle between the first hardware element and the second hardware element based on the first signals;
• determine a second value of the lid angle based on the calibration parameter, the reliability value, and the first value of the lid angle;
• and
• control a function of the device based on the second value of the lid angle.

A non-transitory computer-readable medium having contents which configure a processing unit of an electronic apparatus to perform a method, the method comprising:

• receiving, from a first magnetometer and a second magnetometer of the electronic apparatus, first signals indicating measurements of a magnetic field, the first magnetometer and the second magnetometer being in a first hardware element and a second hardware element, respectively, of the electronic apparatus;
• determining a calibration parameter based on the first signals, the calibration parameter indicating a condition of calibration of the first and second magnetometers;
• determining a reliability value based on the first signals, the reliability value indicating of a condition of reliability of the first signals;
• determining a first value of a lid angle between the first hardware element and the second hardware element based on the first signals;
• determining a second value of the lid angle based on the calibration parameter, the reliability value, and the first value of the lid angle;
• and
• controlling a function of the electronic apparatus based on the second value of the lid angle.
