Abstract: A pedestrian navigation system for navigating a foot apparatus comprises a system communication unit, a map database, a step data generation unit, a navigation path analysis unit and a feedback unit. The system communication unit communicates with an apparatus communication unit of the foot apparatus. The step data generation unit generates step data according to the sensing data of the foot apparatus. The navigation path analysis unit determines a navigation path and determines a heading direction of the foot apparatus. A turning direction and a turning angle are generated according to the navigation path and the heading direction. The feedback unit receives the turning direction and the turning angle to generate a feedback signal. The indication unit generates an indication signal according to the feedback signal to indicate the turning direction and the turning angle.
