The controller 180 obtains a map of a location corresponding to the user's voice from the map information unit, and displays the user's voice on the touch screen 400 as illustrated in (7-3) of FIG. 7. The map 430 of the corresponding location is displayed.

And, as shown in (7-3) of Figure 7 "destin." Displayed on the touch screen 400. Icon 433 is selected.

Then, the location corresponding to the user's voice becomes the destination, and navigation guidance from the current location of the terminal to the destination begins to be performed as shown in (7-4) of FIG. 7.

In the above, it is illustrated that a desired position for a navigation function is input through voice recognition. However, the present invention is not limited thereto, and the desired position may also be input through manipulation of the user input unit 130. This will be understood by those skilled in the art, even if there is no separate description, a detailed description thereof will be omitted for simplicity of the present specification.

The navigation function activated during the video communication will be described in more detail with reference to FIG. 8.

In FIG. 8 (8-1A), the touch screen 400 (hereinafter also referred to as "user touch screen") of the above-described portable terminal 100 (hereinafter referred to as "user portable terminal") of the terminal user is displayed. have. In FIG. 8 (8-1B), the touch screen 500 (hereinafter referred to as "relative touch screen") of the mobile terminal (hereinafter referred to as "relative portable terminal") of the counterpart of the video call is displayed. .

If the user's portable terminal 100 activates the navigation function during the video communication [S51], the user's portable terminal 100 transmits a map image according to the navigation function to the counterpart's mobile terminal during the video communication. Accordingly, the transmitted map image 530 is displayed on the counterpart touch screen 500 as shown in (8-1B) of FIG. 8 [S52].

The counterpart portable terminal transmits its location (for example, a location according to a location information system such as GPS) to the user portable terminal 100. Accordingly, the user portable terminal 100 may determine the location of the counterpart portable terminal.

Then, as described above in the user portable terminal 100, a desired position is input through voice recognition, for example.

Then, the user portable terminal 100 grasps and displays the map image 430 according to the desired position, as shown in (8-2A) of FIG. 8. In addition, the controller 180 may control to display information on the distance between the position of the user portable terminal and the desired position. In addition, the controller 180 may control to display information on the distance between the location of the counterpart mobile terminal and the desired location on the user touch screen 400.

The user portable terminal 100 transmits the determined map image and the information about the distance to the counterpart portable terminal.

Then, as shown in (8-2B) of FIG. 8, the counterpart mobile terminal may receive the transmitted map image and information on the distance and display the information on the counterpart touch screen 500.

Accordingly, the terminal user and the counterpart can easily determine an appointment place, for example, while viewing the identified map image together.

In addition, the user and the counterpart are displayed in the user touch screen and the counterpart touch screen. When the icon is selected, the user portable terminal 100 and the counterpart portable terminal provide navigation guidance to the desired location for the user and the counterpart respectively.

The navigation function activated during the video communication will be described in more detail with reference to FIG. 9.

As shown in (9-1A) of FIG. 9, predetermined marks, letters and / or symbols are written by the user on a map image 430 of the user touch screen 400, for example, by a stylus pen.

Then, the user portable terminal 100 transmits the written indications, letters and / or symbols to the counterpart mobile terminal in real time.

Then, the counterpart mobile terminal displays the received display, text, and / or symbols in real time on the map image 530 of the touch screen 500.

Accordingly, the terminal user and the counterpart may smoothly discuss and set an appointment location, for example.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

For example, the above-described method can be embodied as computer readable code on a medium on which a program is recorded. The computer-readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, which are also implemented in the form of carrier waves (eg, transmission over the Internet). It also includes. In addition, the computer may include the controller 180 of the terminal.

Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
