A pedestrian navigation system provides distance information and travel directions to a destination. The system includes a pedestrian navigation device for navigating a pedestrian's route by means of a vibration, a server for offering navigation information to the pedestrian navigation device, a network for connecting the pedestrian navigation device with the server to permit communication between each other, and a GPS for offering position information to the pedestrian navigation device. Further, the pedestrian navigation device can include a speaker for outputting a guide voice based on the user's present position information, so as to start a voice guide after generating vibration, thereby facilitating verification of the guidance information provided.

A pedestrian navigation system, an information delivery server, and a program for naturally guiding (such as speech-guiding) the user of a portable terminal at an intersection are disclosed. An information delivery server includes a map database containing data such as nodes including paths constituting intersections, links, and costs of the links, a path seeking section, an intersection path judging section for detecting a path passing through an intersection from guidance paths which the path seeking section has sought, a guidance point determining section which determines a guidance point for path guidance, a guidance data creating section which determines a guidance pattern of path guidance according to the guidance point, and a data delivering section for delivering map data, guidance path data, and guidance data to a portable terminal. The guidance point determining section selects a specific node out of all the nodes constituting intersections as a guidance point.

An on-foot pedestrian navigation module useful for pedestrian navigation when operated with at least a control unit and another on-foot pedestrian navigation module, comprising (a) at least a first sensor unit and a second sensor unit, wherein each sensor unit including an up / down sensor adapted for sensing an ‘up’ condition and a ‘down’ condition associated with relative displacement of the module with respect to a surface, and a signal transmitter / receiver adapted, in response to an activation signal coming from a module controller, for generating a propagating signal (b) a module controller for controlling the operation of the module in response to a control signal coming from the control unit and (c) a communication unit for enabling said module to communicate with said at least the control unit and other module, thereby facilitating collecting motion data at the control unit and integrating the motion data with motion data coming from the other module, the motion data being indicative of a condition of each up / down sensor and receipt of the propagating signal by at least two sensor units of said other module, and wherein the motion data is useful for determining a momentary position of the pedestrian's foot during motion.

The invention discloses a pedestrian inertial navigation system and method assisted by a machine learning algorithm and a model, belonging to the field of inertial and integrated navigation and the field of artificial intelligence. The method recognizes different types of gait characteristics of the human body through inertial / geomagnetic sensor components installed on human feet, and sensor components installed centrally or distributed on other parts of the human body. Adaptively adopt different machine learning algorithms and models to train the sensor information of the foot and other parts, and realize the purpose of simulating the inertial sensor information of the foot through the sensor information of other parts, so that real-time fault detection can be performed on the pedestrian navigation system, and It can predict within a gait cycle before the foot inertial sensor exceeds the range, and then based on one or more virtual foot inertial sensor information generated by simulation, the pedestrian navigation system can be constructed through the principle of system reconstruction to realize fault and overshooting. Inertial Pedestrian Navigation Function in Range Conditions.

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.
