The traditional location based services (LSB) applications that require pedestrians' position, developments in pedestrian positioning systems present a great potential to assist users with special needs, eg, people with spatial disorientation issues. In a spatial disorientation episode a person hesitates about her/his surroundings or gets lost in otherwise familiar environments. Research in pedestrian dead reckoning has shown outstanding results about the user's position based on human locomotion patterns. In this paper, we leverage the great
