Abstract

A portable terminal has a function of walking navigation. The direction of a destination is displayed by an indicating arrow that always points in the direction of the destination. In the navigation processing, the user enters data to select a menu and/or set retrieving conditions on the setup screen. At first, the user gets the location information of the portable terminal, represented by a latitude/longitude or coordinates and an altitude, for example. Then, the user gets the direction information of the portable terminal, which is the direction of the tip of the portable terminal as determined by a compass, a gyro, or a clinometer. The location information and the direction information are set as terminal information for the retrieving conditions. The system controls retrieving of the database and retrieves the information corresponding to the selected menu, such as route guidance.

Claims

1. A portable terminal, comprising:

a device for getting location information denoting a resent place of said portable terminal;

a device for getting a direction information denoting an orientation of said portable terminal;

an input device for inputting a destination; and

a display,

wherein

said display displays positions of said destination and said present place, and a relation of said direction and a direction from said present place to said destination, and

said display changes according to a change of said direction of said portable terminal orientation for walking navigation.

2. A portable terminal according to claim 1,

wherein said direction from said present place to said inputted destination is denoted with an orientation of line.

3. A portable terminal according to claim 1,

wherein a distance between said present place and said destination is denoted with a number.

4. A portable terminal according to claim 1,

wherein said direction from said present place to the location of said another portable terminal is displayed using the symbols denoting the said present location and said location of another portable terminal.

5. A portable terminal according to claim 2,

wherein a distance between said present position and said destination is denoted with a length of said line.

15. A portable terminal with walking navigation according to claim 1, further comprising:

a device for retrieving a route from said present place to said destination, wherein

said display displays said route and displays a direction of movement by the arrow.

16. A portable terminal with walking navigation according to claim 15, wherein said display further displays said grid information of said route.

17. A portable terminal with walking navigation according to claim 15,

wherein said display displays said route with a bent line using symbols denoting starting and ending points and displays symbols denoting said present place on said route.

20. A portable terminal with walking navigation according to claim 17,

wherein said display displays said route with a bent line using symbols denoting starting and ending points and displays symbols denoting said present place on said route.

6. A portable terminal, comprising:

a device for getting location information denoting a present place of said portable terminal;

a device for getting direction information denoting an orientation of said portable terminal;

a device connected to a server; and

a display,

wherein

said device connected to said server outputting said location information and said direction information and receiving retrieved information based on said outputted information at said server, and

said display displays said retrieved information.

7. A portable terminal according to claim 6,

wherein said information is stores or roads information.

8. A portable terminal according to claim 6,

wherein said display displays said retrieved information as lists.

9. A portable terminal according to claim 6, further comprising an input device,

wherein said retrieved information is of stores and is displayed on said display as store lists, and

when one of said stores is selected by said input device, said display displays detailed information of said selected store.

10. A portable terminal, comprising:

a device for getting location information denoting a present place of said portable terminal;

a device for getting direction information denoting an orientation of said portable terminal;

a device for getting a location information of another portable terminal from said another terminal via connected network; and

a display,

wherein

said display displays positions of said destination and said present place, and a relation of said direction and a direction from said present place to said destination,

and said display changes according to a change of said direction of said portable terminal orientation for walking navigation.

11. A portable terminal according to claim 10,

wherein said direction from said present place to said location of another portable terminal is denoted with an orientation of line.

12. A portable terminal according to claim 10,

wherein said direction from said present place to the location of said another portable terminal is displayed using the symbols denoting the said present location and said location of another portable terminal.

13. A portable terminal according to claim 10,

wherein said display displays a distance between said present location to said location of another portable terminal with a number.

14. A portable terminal according to claim 11,

wherein a distance between said present location to said location of another portable terminal is denoted with a length of said line.

18. A portable terminal with walking navigation according to claim 10, further comprising:

a device for retrieving a route from said present place to said destination, wherein

said display displays said route and displays a direction of movement by the arrow.

19. A potable terminal with walking navigation according to claim 18, wherein said display further displays said grid information of said route.
