As another embodiment of the present invention, the guide information may be vibration information, and the guide information output unit 204 outputs the vibration information by using the vibration motor of the mobile communication terminal 101. The vibration information refers to a continuous vibration pattern, and may be guided by the vibration pattern previously promised to the visually impaired. For example, the number of primary vibrations may indicate a direction, the number of secondary vibrations may indicate a distance from an obstacle, and the number of third vibrations may indicate obstacle information.

Positioning sensors 402, 403, and 404 are provided in a plurality of obstacles in the building.

When the destination of the visually impaired 401 is a specific office on the fifth floor, the first visually impaired 401 inputs the fifth floor or an office lake into the mobile communication terminal 101 as destination information. Thereafter, the destination information is transmitted to the blind guide server 103. As shown in the drawing, when the visually impaired person arrives near the elevator on the first floor, after receiving the positioning radio wave from the mobile communication terminal 101 possessed by the visually impaired by the positioning sensor 402 located in the elevator, Transfer to the visually impaired server (103).
