Terminal device and recording medium
First Claim
1. A terminal device comprising:
- a positional information acquisition unit which acquires positional information indicating a position of the terminal device;
a destination information acquisition unit which acquires destination information specifying a destination;
a navigation unit which acquires from a server, upon activation, data indicating a route from a position specified by the positional information acquired by said positional information acquisition unit to a destination specified by the destination information, and which navigates the routes;
a distance acquisition unit which acquires a distance between the position specified by the positional information acquired by said positional information acquisition unit and the destination specified by said destination information;
a determining unit which repetitively determines whether or not the distance acquired by said distance acquisition unit is larger than a specified value; and
an activation control unit which waits without activating said navigation unit until the determining unit determines that the distance is larger than the specified value, and activates said navigation unit to start navigation of the route from the position of the terminal device to the destination when the determining unit has determined that the distance is larger than the specified value,wherein the destination information acquisition unit includes;
a counterpart information memory unit which stores counterpart information for each counterpart, anda reception unit which receives, from the server, information specifying a position of a terminal device of a counterpart as the destination information, the counterpart being selected from among counterparts whose counterparts whose counterpart information is stored in the counterpart information memory unit,wherein the activation control unit displays, on a monitor of the terminal device a route from the position of the terminal device to the position of the terminal device of the selected counterpart;
wherein data is sent from the server to the terminal device of the selected counterpart, the sent data being the same as the data indicating the route acquired by the navigation unit, andwherein the terminal device of the selected counterpart displays, on a monitor of the terminal device of the selected counterpart, the route indicated by the data received from the server, the route displaced by the terminal device of the selected counterpart being the same as the route displayed by the activation control unit.

Abstract
A mobile phone terminal has a positional information acquisition unit acquiring present positional information indicating a present position, a destination information acquisition unit acquiring destination information specifying a destination (where to return, and where to go), a navigation unit navigating a route from a position specified by the present positional information acquired by the positional information acquisition unit to a destination specified by the destination information, upon activation, a distance acquisition unit acquiring a distance between a position specified by the present positional information acquired by the positional information acquisition unit and a destination specified by the destination information, and an activation control unit activating the navigation unit depending on a distance acquired by the distance acquisition unit.

11. A nontransitory recording medium in which a program is recorded, the program allowing a computer to perform:
-
a positional information acquisition step of acquiring positional information indicating a position of the terminal device; a destination information acquisition step of acquiring destination information specifying a destination; a distance acquisition step of acquiring a distance between the position indicated by the positional information and the destination indicated by the destination information; a determination step of repetitively determining whether or not the distance is larger than a specified value; and an activation control step of waiting without activating a navigation unit which acquires from a server data indicating a route from the position indicated by the positional information to the destination specified by the destination information and which navigates the route until it is determined that the distance is larger than the specified value, and activating the navigation unit to start navigation of the route from the position of the terminal device to the destination when it has been determined that the distance is larger than the specified value, wherein in the destination information acquisition step; information specifying a position of a terminal device of a counterpart is received from the server as the destination information, the counterpart being selected from among counterparts whose counterpart information is stored in a memory unit which stores counterpart information for each counterpart; wherein the activation control unit displays, on a monitor of the terminal device a route from the position of the terminal device of the selected counterpart is displayed on a monitor of the terminal device; wherein data is sent from the server to the terminal device of the selected counterpart, the sent data being the same as the data indicating the route acquired by the navigation unit; and wherein the terminal device of the selected counterpart displays the route indicated by the data received from the server, the route displayed by the terminal device of the selected counterpart being the same as the route displayed in the activation control step.
