Embodiments of the present invention will be described below with reference to the drawings.

A portable guide device 1 shown in FIG. 1 includes a GPS sensor 2, a data storage unit 3, a calculation unit 4, an azimuth sensor 5, a tilt sensor 6, a display unit 7, and an input unit 8.

The GPS sensor 2 receives a signal from an artificial satellite 10 constituting the GPS, and converts the signal into an arithmetic unit 4
Send to The calculation unit 4 calculates the latitude, longitude, and altitude of the device 1 itself based on the signal from the GPS sensor 2.

The data storage unit 3 stores latitude, longitude, altitude, ground appearance data, and name data in association with each other. The surface appearance data includes latitude, longitude,
Mesh elevation data on a two-dimensional plane according to altitude, aerial photograph or satellite image showing vegetation, etc. can be used,
The name data includes the location name according to the latitude, longitude, and altitude, and the attribute (mountain, hill, river, building, cape,
Can be used, and vector data of names of roads, buildings, and the like at positions corresponding to latitude, longitude, and altitude may be stored together. . The aerial photograph, the altitude data, and the name data can be, for example, those issued by the Geographical Survey Institute, and the satellite images, for example, those issued by the Remote Sensing Technology Center can be used.

The arithmetic unit 4 calculates the appearance of the ground surface at a set azimuth and a set angle with respect to a horizontal plane from the latitude, longitude, and altitude of the device 1 itself calculated based on the signal from the GPS sensor 2 as described above. Image data corresponding to the name and the name is calculated from the data stored in the data storage unit 3. The calculation for obtaining image data corresponding to the appearance of the ground from a certain position can be performed in the same manner as the calculation for obtaining image data in a conventional flight simulator. The final image data is obtained such that the displayed name of the place, the name of the building or the like is superimposed on the display image based on the image data corresponding to the appearance of the ground surface.

The direction sensor 5 detects the direction in which the display surface of the display unit 7 faces, and sends a detection signal to the calculation unit 4. The calculation unit 4 performs the calculation for obtaining the image data.
The set azimuth is determined based on the detected azimuth and the calculation is performed. For example, when the display surface faces south, the set azimuth is set to 1 such that the set azimuth is north.
By shifting the scene by 80 degrees, the scene and the name corresponding to the direction of the line of sight of the device user who sees the scene and the display surface in front can be displayed. And the name corresponding to the direction of the line of sight of the device user who looks at the display 1 with the device 1 aside and swings his / her head sideways can be displayed. It is preferable that the shift angle of the set azimuth with respect to the detected azimuth can be changed by input from the input unit 8. Further, it may be possible to always set a state where an arbitrary fixed direction, for example, north is the set direction, and in this case, a function as a direction magnet can also be achieved.

The tilt sensor 6 detects an angle formed by a normal line of the display surface of the display unit 7 with respect to a horizontal plane, and sends a detection signal to the arithmetic unit 4. The calculation unit 4 determines the set angle based on the detected angle and performs the calculation when calculating the image data. For example, by setting the deviation of the set angle with respect to the detection angle formed by the normal of the display surface with respect to the horizontal plane to zero, the elevation angle or depression angle of the line of sight of the device user and the angle formed by the normal of the display surface with respect to the horizontal plane If is made equal, it is possible to display a scene and a name corresponding to the elevation angle or the depression angle. It is preferable that the shift angle of the set angle with respect to the detection angle can be changed by an input from the input unit 8. In addition, an arrangement may be made in which an arbitrary constant angle can always be set to the set angle.

The display section 7 displays an image corresponding to the obtained image data, and can be constituted by, for example, a liquid crystal display device.
