At the same time, the voice conversion unit 311 is driven to convert spot information at the position, for example, announcement information for guidance, into voice and output it (S209).

The control unit 308 also has a movement history storage unit in an internal storage device.
The fact that the temple has been entered from the mountain gate 401 is stored as a movement history (S210).

Next, the control unit 308 determines whether or not the current position is an exit with reference to the movement history (S211).
If it is not an exit, it moves to the next visit point by a map or floor layout, standard sightseeing route, and voice announcement (S212).

  When the movement is completed, the process returns to step S201 at the next point, the portable terminal device is brought close to the IC tag, and the three-dimensional position information is acquired.

Repeat the flow of Fig. 7 every time you move, accumulate the movement history and finally reach the exit,
In step S211, it is determined as an exit and the navigation is terminated.

When the owner of a mobile device wants to tour in his / her favorite order regardless of the standard tourism route,
By the map and floor layout on the image display unit 307,
When you go to the spot you want to see and read the 3D position information, record it in the movement history,
If you make a rearranged program to bring the spot that you skipped on the standard sightseeing route to the end of the sightseeing route,

There are many things that navigate by directions such as turning right. However, in the case of temple sightseeing, it is rare to go in a certain direction,
Rotation, advance, retreat, etc. move in a complex combination,
It is important to monitor the absolute azimuth and identify the direction of the viewer to indicate the traveling direction, or to indicate the traveling direction in the absolute azimuth.
The direction detection unit 110 can detect an absolute direction, collate with map information, and navigate with an optimal expression.

Since the IC tag can increase the amount of stored information, not only the three-dimensional position information of the position,
Simple spot information at that point can also be stored. For example, when the treasure displayed in this example is replaced,
Just rewrite the spot information on the IC tag at that point.

In this embodiment, since the required navigation information is downloaded from the center,
Navigation information corresponding to the place where navigation is performed
Since it can also be obtained at department stores, etc., it can handle a variety of navigation without changing the mobile terminal device.

At present, mobile phones with digital cameras have already been put into practical use.
Mobile phones with navigation functions are also appearing.
Small and high-performance PDAs (personal digital assistants) are also in widespread use.
