In addition, the terminal device 100 is a terminal for performing voice or data communication using the communication network 10, and stores a browser, a program, and a protocol for communicating with the service device 200 via the communication network 10. It refers to a terminal having a microprocessor for operating and controlling various programs. That is, the terminal device 100 may be any terminal as long as the service device 200 and the server-client communication are possible, and are a broad concept including all communication computing devices such as a notebook computer, a mobile communication terminal, and a PDA. On the other hand, the terminal device 10 is preferably manufactured in the form having a touch screen, but is not necessarily limited thereto.

The terminal device 100 may receive a location service from the service device 200, register a member for the location service, or download a related application to receive the location service through the application.

In detail, the terminal device 100 transmits identification information (for example, a unique identification number such as a mobile phone number) of the counterpart terminal device to the service device 200 in order to confirm the exact location of the counterpart. Request information. Accordingly, the terminal device 100 can receive the location information obtained by analyzing the image photographed by the other party from the service device 200 and receive the photographed image together to determine the current location of the other party.

In addition, when the user wants to receive the information of the interest field of the user at the location of the current counterpart identified through the location information, the terminal device 100 receives information on the field of interest from the user, and the service device according to the input information. By requesting the interest information to the 200, the searched interest information related to the location information received from the service device 200 may be provided. Here, the interest information may be, for example, the result information obtained by searching for a restaurant near the current location of the counterpart when the user inputs a restaurant as the field of interest. The interest information may be received in a general data form and a data form applicable to a map or navigation application.

Accordingly, the terminal device 100 may display the interest information on a map by reflecting the received interest information on a map application or a navigation application. In addition, the terminal device 100 may display the interest information on the screen in the form of a message. Accordingly, the user may check the interest information displayed on the screen and, for example, use it to determine an appointment place with the counterpart.
