When the distance appears, instead of the meter (M) to convert the number of steps or time that can be easily recognized by the disabled person to output. Therefore, instead of saying “turn left in front of 1 meter ahead”, print “go straight five steps, turn left”, and turn “four steps, three steps, two steps, one step, here left every time a pedestrian moves. It outputs a guide that decreases step by step so that you can change the path at the correct location. Accordingly, it is possible to change the route at the correct position in consideration of the different stride length for each person with a disability. Therefore, it makes it possible for the disabled to find a destination more conveniently.

On the other hand, the path controller 260 controls to output the recording path information preferentially when the location guide mode is selected. That is, when generating the path corresponding to the destination, if the recording path information corresponding to the destination exists in the recording information storage unit 243, the recording path information is output without interpreting the map information. This is because the recording path information explains the surrounding situation and path in more detail from the guardian's point of view.

With reference to Figs. 1 to 3, a process for a person with a disability finding a destination using a cane 1 for a disabled person according to the present invention having such a configuration will be described.

First, as illustrated in FIG. 3, the handicapped person grabs the cane 100 and presses the mode selection button 221.
