In addition, the navigation according to the present invention includes a receiving unit for receiving location information from the GPS; A key input unit for inputting a landmark for POI search; A control unit for setting a search range around the landmark and searching for a POI according to the type of the POI; It includes a display unit for displaying a landmark and at least one POI under the control of the controller.

The above-mentioned objects, features and advantages will become more apparent from the following detailed description in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a navigation according to the present invention.

Referring to FIG. 1, the receiver 100 receives location information from a GPS.

The key input unit 110 includes a plurality of function keys as a user interface, and outputs key signals for the keys to the controller 150.

Preferably, a landmark is input from the user for POI search.

The storage unit 120 stores a predetermined program for controlling the overall operation of the navigation and various data input and output when the control operation of the navigation is performed.

Preferably, the memory 120 stores life names, abbreviations, and abbreviations of the landmarks.

The sound output unit 130 includes a speaker provided in the navigation, and outputs the sound signal stored in the storage unit 120 in an audible state under the control of the controller 150.

The display unit 140 expresses a landmark and at least one POI under the control of the controller 150.

The controller 150 sets a search range around the landmark and searches for a POI according to the type of the POI.

In addition, the controller 150 searches the search range by distance or block unit.

In addition, the controller 150 sets the landmark as the search center, and when the user designates a specific direction of the landmark, sets the search range to be eccentric in the designated direction.

In addition, the control unit 150 navigation, characterized in that the partial search by any one or more of the name, abbreviation or abbreviation of the landmark stored in the storage (120).

In addition, when searching for the POI around the landmark, the controller 150 controls the number of expressions if the number of POIs is large or small, and expands or reduces the search range.

2 is a flowchart of a POI search method using a landmark according to the present invention.

Referring to FIG. 2, a user inputs a landmark for POI search (S200). Preferably, the landmark is a suitable object as a target for identifying a certain area, and it should be one that is prominently noticeable among the surrounding landscape, such as Namsan Tower or Seoul Namdaemun, which has historical characteristics.

When the landmark is input, the type of POI is selected (S210). The category may be registered in advance in the navigation, such as restaurants, fast food, gas stations, banks, maintenance shops, or can directly register the category as a user. Subsequently, a search range is set based on the landmark (S220). For example, if the user selects a restaurant by POI, at least one restaurant around the landmark is searched (S230).

Preferably, the search range can be searched by distance or block unit. For example, a radius of 50m, 100m, 1km, or a block containing a landmark may be searched around the landmark in units of blocks.

In addition, the search range may be set eccentrically in a direction designated by the user based on the landmark. That is, when searching based on a landmark, most searches are performed by a radius, but when the user knows that the POI to be found is located approximately downward of the landmark, the search range is eccentrically set downward of the landmark.

A detailed description will be made with reference to FIG. 3B.

Also, for example, if there are about 50 restaurants around the landmark, the user may be confused to see, no matter how well arranged on the screen. Therefore, the number of POIs to be displayed is controlled.

Preferably, the search range is expanded or reduced according to the number of expressions of the POI.

That is, if there are too many POIs around the landmark, the search range is narrowed. If the POI is too small, the search range is expanded.

In addition, when the name of a landmark is input, the name known to each user is somewhat different. For example, Gangnam Finance Center located in Yeoksam Station is called Life Tower or Star Tower and its abbreviation or abbreviation is called GFC. Therefore, the navigation unit stores life-saving names, abbreviations, or abbreviations of major landmarks, and the user can partially search by a known name.

3A to 3C are diagrams illustrating exemplary embodiments of a POI search method using landmarks according to the present invention.

Referring to FIG. 3A, when the user does not remember the name of the POI to be searched for, but only remembers that it is near 63 building, the landmark is 63 building, the search range is 50m, and the POI type is entered as a restaurant. Four restaurants were searched around the 63 building. When the user selects one place from the searched restaurant, the user guides the shortest path from the current location to the selected restaurant.

Preferably, in FIG. 3A, there are two search range circles around the 63 building. When the search range is set small, the POI cannot be searched and enlarged.

When searching for POI, the search range is automatically expanded or reduced according to the number of expressions of POI.

Referring to FIG. 3B, the difference with FIG. 3A is that the search range is designated by the user. In other words, if you know that the convenience store you are looking for is around COEX, but you know that it is approximately to the left or west of COEX, searching within a few meters of the radius of COEX will find more convenience stores. Falls. Therefore, when the user sets the search criteria to the left or west of COEX, the user searches for and displays a convenience store located on the left side as shown in FIG. 3B.

Referring to FIG. 3C, the user designates a landmark as a Gangnam Finance Center and searches for restaurants within about 1 km of the surroundings. In order to increase the visibility of the searched restaurant, it is represented by an icon like an alphabet. Preferably, the icon may be represented by changing the display setting to at least one of numbers, colors, Mooney, images, and sounds.

In addition, the searched restaurants may be arranged in a list on a portion of the screen, and the detailed information of the restaurants may be checked by selecting the list or selecting an icon displayed on a map.

In summary, the present invention can search by using neighboring landmarks even if the user does not know the name of the POI to be searched for, so that the user can receive route guidance to the POI to have a wide range of search options and to go comfortably and easily.
