Stabilizing orientation values of an electronic device

An electronic device comprising:

• a memory;
• a first sensor for providing first sensor readings in respect of at least one first sensor axis, the first sensor comprising a gyroscope;
• a second sensor for providing second sensor readings in respect of at least one second sensor axis;
• and,
• a processor coupled to the memory, the first sensor, and the second sensor the processor being configured to stabilize the orientation values of the electronic device by:
• obtaining first sensor readings from the first sensor;
• obtaining second sensor readings from the second sensor;
• evaluating the first sensor readings and the second sensor readings to determine whether the electronic device is stationary;
• locking the orientation values when the electronic device is stationary, wherein locking configures the electronic device to prevent updating of the orientation values until the orientation values have been unlocked;
• collecting at least one of further first sensor readings and further second sensor readings while the orientation values are locked;
• determining whether the orientation of the electronic device is changing by more than a threshold amount based on one or more of the further first sensor readings and the further second sensor readings;
• and
• unlocking the orientation values for updating based on the further sensor readings when the orientation of the electronic device is changing by more than the threshold amount, wherein unlocking configures the electronic device to allow further updating of the orientation values.

A non-transitory computer readable storage medium comprising computer-executable instructions for controlling sensor use on an electronic device by:

• obtaining first sensor readings from a first sensor provided on the electronic device, the first sensor comprising a gyroscope;
• obtaining second sensor readings from a second sensor provided on the electronic device;
• evaluating the first sensor readings and the second sensor readings to determine that the orientation of the electronic device is stationary;
• locking the orientation values, wherein locking configures the electronic device to prevent updating of the orientation values until the orientation values have been unlocked;
• collecting at least one of first sensor readings and second sensor readings while the orientation values are locked;
• determining that the orientation of the electronic device is changing by more than a threshold amount based on one or more of the first sensor readings and second sensor readings collected while the orientation values were locked;
• and
• unlocking the orientation values, wherein unlocking configures the electronic device to allow further updating of the orientation values.
