The present invention relates to a method and system for setting a specific point using navigation.

In general, a vehicle information terminal or telematics terminal provides a navigation function. The navigation function is a representative function of an information terminal. The navigation function is an application that searches for a driving route from a starting point or a current position of a vehicle to a desired point, matches the map data, displays the matching route, and guides the driving route to the driver.

The telematics terminal stores digital map data for multi-levels having different map periods (main objects) for each accumulation.

The existing navigation system moves a map on the screen of the terminal by a touch screen or a jog stick, and then selects a desired specific point based on the "cycle name" displayed on the screen of the terminal. At this time, the algorithm searches for the period closest to the point displayed on the screen from the detailed level to the wide level based on the latitude and longitude coordinates, and selects the period closest to the specific point selected by the user as the final point.

However, when the user selects a specific point based on the cycle name displayed on the screen of the terminal, the cycle on the screen selected by the user may be a cycle at a position different from the cycle determined internally of the actual telematics terminal.

For example, suppose a user selects 'Gangnam Station' from the wide-area map image by a touch screen or the like. The navigation system may recognize Gangnam Station as a destination by searching the maps for each accumulation level, but other cycles such as 'New York Confectionery', 'Yeoksam Tax Office', and 'Korea Industry' near Gangnam Station may be recognized as destinations. Can be confusing to users.

According to the present invention, when a specific point is input on a map screen of a specific accumulation in an information terminal having a navigation function, the map is stored differently for each accumulation period close to the input point, and the user directly displays the map on the screen of the terminal. It is an object of the present invention to provide a method and system for setting a destination using navigation, which enables the user to select a destination accurately.

According to an embodiment of the present invention, a method of setting a specific point using navigation comprises: receiving a specific point according to a navigation function; Displaying the path periods by searching for path periods adjacent to the received position information of the specific point; And setting the path period selected by the user among the displayed path periods as the final point.

In addition, the information terminal according to the present invention, the GPS receiver for receiving position information from a Global Positioning System (GPS) satellite; An input unit for receiving a specific point according to a navigation function; A display unit for displaying the specific point; And a controller configured to search for path periods close to the input specific point, display the path periods on the display unit, and set a path period selected by a user among the displayed path periods as a detailed point.

The above objects, features and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals denote like elements throughout the specification.
