Abstract
A system, device and method of calibrating a sensor determine a sensor vector associated with a subject; process the sensor vector; determine a sensor elevation angle as a prediction of the subject's body elevation from a result of processing the sensor vector; and perform calibration using the sensor vector, sensor elevation angle, and a gravity vector.
