A lead route guidance system capable of displaying route guidance not causing the user to be confused by the difference between the line of vision and the route guidance image, a portable route lead guidance device, and program are provided. The lead route guidance system comprises route storage means storing a route from a start point to a destination, route guidance image creating means for creating a route guidance image () containing a route image () for specifying the route and a lead image () for leading the route by displaying a lead position on the route ahead of the current position of the user, a display screen () for displaying thereon the route guidance image (), walk detecting means for detecting walk of the user, and lead position updating means for updating the lead position depending on the walk of the user when the walk of the user is detected.

Lead route guidance system, portable route lead guidance device, and program

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.

Pedestrian navigation system, information delivery server, and program

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.

Pedestrian navigation device, pedestrian navigation system, pedestrian navigation method and program

A pedestrian navigation device (A) of this invention has a position information reception unit (), which obtains current position information from a GPS (); a position information analysis unit (), which calculates the current position by analyzing received current position information; a MAPDB (Map Data Base) (), which stores map information; a multi-path control unit (), which specifies a multi-path control distance to control multi-path interference; a central processing portion (), which calculates current position display information, based on the current position calculated by the position information analysis unit (), on map information stored in the MAPDB (), and on the multi-path control distance specified by the multi-path control unit (); a display unit (), which displays current position display information; and an input unit (), which inputs distance specification value and route search conditions and issues instructions to begin navigation. By this means, a pedestrian navigation device is provided, which enables to accurately navigate the route of a pedestrian by appropriately correcting the multi-path interference.

Walker navigation device, walker navigation method, and program

A pedestrian navigation device (A) of this invention comprises a position information reception portion (), which obtains current position information from a GPS (); a position information analysis portion (), which analyzes current position information received by the position information reception portion () and calculates the current position; a MAPDB (Map Data Base) (), which stores map information; a central processing portion (), which calculates current position display information, based on the current position calculated by the position information analysis portion () and on map information stored in the MAPDB (); a display portion, which displays current position display information calculated by the central processing portion (); and an input portion (), which inputs route search conditions and issues instructions to begin navigation. By this means, a pedestrian navigation device is provided which, when navigating a pedestrian route, is able to accurately detect the direction of advance through judgment of stops and suppression of meandering.
