The present invention relates to body position detection. In order to improve body position detection, a computer-implemented method is provided that comprises the steps of:a) receiving (210) accelerometer data from an accelerometer mounted on a user,wherein the received accelerometer data comprises three acceleration components including a first acceleration component in a first axis direction, a second acceleration component in a second axis direction substantially perpendicular to the first axis direction, and a third acceleration component in a third axis direction substantially perpendicular to a plane formed by the first and second axes; andwherein the first axis direction is parallel to a frontal axis of the user, the second axis direction is parallel to a longitudinal axis of the user, and the third axis direction is parallel to a sagittal axis of the user;b) determining (220), based on the received accelerometer data, the body position based on one or more of:- a comparison between an absolute value of a projection of a gravity vector on a plane formed by two of the first, second, and third axes and an absolute value of an acceleration component in a remaining axis direction;- a comparison between absolute values of two of the three acceleration components; and- a sign of a value of one of the three acceleration components.
