The control unit 180 obtains a map of the position corresponding to the user voice from the map information unit and displays the user voice on the touch screen 400 as shown in (7-3) And displays the map 430 of the corresponding position.

Then, as shown in (7-3) of Fig. 7, the "destin." Displayed on the touch screen 400 is displayed. The icon 433 is selected.

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

In the above description, the desired position for the navigation function is input through speech recognition. However, the present invention is not limited to this, and the desired position may also be input through the operation of the user input unit 130. [ It will be appreciated by those skilled in the art that without further explanation, a detailed description thereof will be omitted for the sake of simplicity of the present specification.

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

8A, a touch screen 400 (hereinafter also referred to as a "user touch screen") of the portable terminal 100 (hereinafter also referred to as "user portable terminal") of the terminal user is displayed have. 8B, a touch screen 500 (hereinafter referred to as "counterpart touch screen") of the portable terminal of the other party of the video call (hereinafter also referred to as "counterpart portable terminal") is displayed .

If the navigation function of the user's portable terminal 100 is activated during the image communication (S51), the map image corresponding to the navigation function is transmitted to the partner portable terminal during the image communication. Therefore, as shown in (8-1B) of FIG. 8, the transmitted map image 530 is displayed on the counterpart touch screen 500 (S52).

Then, the counterpart mobile terminal transmits its own position (for example, a position according to a position information system such as GPS) to the user portable terminal 100. Accordingly, the user portable terminal 100 can determine the location of the other portable terminal.

Then, the user portable terminal 100 inputs a desired position through speech recognition, for example, as described above.

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

Then, the user portable terminal 100 transmits the detected map image and the distance information to the counterpart mobile terminal.

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

Therefore, the terminal user and the other party can easily determine, for example, the appointment place while viewing the grasped map image together.

The user and the other party are connected to the user touch screen and the " destin. " 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 other party, respectively.

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

A predetermined mark, letter and / or symbol is written on the map image 430 of the user touch screen 400 by the user, for example, as a stylus pen, as shown in (9-1A) of FIG.

Then, the user portable terminal 100 transmits the handwritten indication, the text and / or the symbol to the counterpart mobile terminal in real time.

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

Accordingly, the terminal user and the other party can mutually more smoothly determine, for example, the appointed place.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

For example, the above-described method can be implemented as a 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 the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . In addition, the computer may include a control unit 180 of the terminal.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
