Claim:
1. A pedestrian navigation system through a foot apparatus of a pedestrian to navigate, which the foot apparatus has a sensor to sense a sensing data of the foot apparatus, an orientation unit to generate an orientation data, an apparatus communication unit to communicate with the pedestrian navigation system through a communication network, and an indication unit, the pedestrian navigation system comprising: a system communication unit for communicating with the apparatus communication unit of the foot apparatus through the communication network; a map database for storing a map data; a step data generation unit for generating step data according to the sensing data from the sensor of the foot apparatus, wherein the step data includes an angle of foot deflection and a distance between steps of the foot apparatus; a navigation path analysis unit coupled with the map database for receiving the map data and the orientation data to form a navigation path, for receiving the step data of the foot apparatus to determine a heading direction of the foot apparatus, and for generating a turning direction and a turning angle by the navigation path analysis unit according to the navigation path and the heading direction; a stepping database coupled with the navigation path analysis unit, and the stepping database records a plurality of historical step data and a personal step model of the pedestrian, and the navigation path analysis unit amends the heading direction according to the historical data and the personal step model of the pedestrian; and a feedback unit coupled with the navigation path analysis unit for receiving the turning direction and the turning angle to generate a feedback signal and for transmitting the feedback signal to the indication unit, wherein the indication unit generates an indication signal according to the feedback signal to indicate the turning direction and the turning angle.
