Abstract
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.
