Abstract

The invention relates to a portable device with improved sensor position change detection. It aims at detecting a change of position of a mobile device relative to a user and, based on this change of position, a change of orientation of the mobile device relative to the user. This allows, when the orientation of the mobile device suddenly changes relative to a user, to keep track of this change. This is particularly useful for position tracking techniques such as Pedestrian Dead Recognition (PDR), which rely on an iterative determination of the orientation of a mobile device relative to the user, and may be affected by a sudden and important change of this relative orientation.
