  FIG. 8 is a diagram illustrating an example of a detailed configuration of the operation unit 114 with braille.

  The embodiment of the present invention described above has the following effects.

  The first effect of the embodiment of the present invention is that, when a visually handicapped person moves with the cane of the present invention, the travel route is changed and the destination is changed while assuming the arrival time at the user's judgment while moving. Therefore, the purpose can be enjoyed at a predetermined time zone at the destination.

  The reason is that by registering the destination, purpose, scheduled date, and time zone to the user in advance, it is possible to select several moving routes or a plurality of similar destination candidates. This is because the arrival time can be notified sequentially.

  The second effect of the embodiment of the present invention is that it is possible to present an optimum travel route for each user.

  The reason is that, as user needs registration information, the type of shopping, the type of food preference, the conditions for walking, etc. are registered in advance and the travel route is presented in consideration of this information. is there.

  The third effect of the embodiment of the present invention is that when a crossing is reached on a road, a user can be notified so that a pedestrian crossing can be safely crossed (for example, crossing while the traffic light is blue). That is.

  The reason is that the signal is already present within the time obtained by adding the current position, the time to the intersection, and the time to cross the pedestrian crossing from the crossing distance at the intersection and the average speed of the user calculated by the data processing unit 203. This is because if the signal can be crossed even in the blue state, it can be announced that the vehicle can be crossed, and if the signal is already in the blue state and cannot be crossed, it can be announced not to cross.

  A fourth effect of the embodiment of the present invention is that signals can be switched without pressing a button of a button type traffic light.

  The reason is that when the visually impaired person's walking stick 100 reaches the Braille block in front of the traffic light, the IC tag reader reads the position information of the Braille block and notifies the traffic signal of the information, and the traffic light switches to blue when triggered by the signal. This is because the operation is performed.
