Dynamically calibrating magnetic sensors

A method for dynamically calibrating a magnetic sensor of a computing device, comprising:

• collecting sensor data for a computing device via a magnetic sensor;
• determining a system state of the computing device;
• and
• dynamically calibrating the magnetic sensor of the computing device based on the sensor data and the system state of the computing device.

At least one machine readable medium having instructions stored therein that, in response to being executed on a processor, cause the processor to:

• determine an output of a magnetic sensor residing within a computing device, wherein the output comprises sensor data;
• determine a system state of the computing device;
• determine a calibration offset value for each system state change event corresponding to the determined system state;
• calculate a combined calibration offset value by summing the calibration offset values for the system state change events;
• calculate a corrected output of the magnetic sensor by subtracting the combined calibration offset value from a value of the output of the magnetic sensor;
• and
• dynamically calibrate the magnetic sensor by updating the calibration offset values for any of the system state change events based on the combined calibration offset value and the corrected output of the magnetic sensor.

An apparatus for dynamically calibrating a magnetic sensor, comprising:

• a magnetic sensor;
• a processor;
• a storage device comprising processor executable code that, when executed by the processor, is configured to:
• collect sensor data for the apparatus via the magnetic sensor;
• and
• determine a system state of the apparatus;
• and
• a controller configured to dynamically calibrate the magnetic sensor based on the sensor data and the system state of the apparatus.
