Examples of events occurring in the mobile terminal include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than a video signal or an audio signal, for example, vibration. Since the video signal or the audio signal may be output through the display unit 151 or the audio output module 152, in this case, the display unit 151 and the audio output module 152 are a kind of alarm unit 153. It may be classified as.

Meanwhile, when the image 300 is displayed on the display unit 151, the controller 180 represents at least one object for location search based on the current region in the image 300 using augmented reality technique. Objects 311 to 314 to be displayed are displayed [S112].

In this case, the object may be a place that is located inside / outside the current area, such as public toilets, restaurants, hospitals, police stations, public telephones, the object (311 ~ 314) is an icon type representing each object It may be represented as.

As shown in FIG. 4, the controller 180 may arrange and display the objects 311 ˜ 314 preset by the user in one region 310 of the image 300.

In this case, the objects 311 ˜ 314 may be moved and fixed to a specific position within the image 300, and may be dragged and dropped.

In this case, the objects 311 ˜ 314 are objects registered and displayed in advance by the user, and the user may add a new object in the current area 310 by selecting the additional object 315 in the area 310. .

In addition, the controller 180 may display the reference point 320 in the image 300 and display information 300N, 300W, 300S, and 300E indicating a plurality of different orientations based on the reference point 320. have. The orientation may be information indicating east, west, north and north directions or information indicating up, down, left, and right directions based on the reference point 320.

In addition, although the reference point 320 is shown as being located at the center position of the image 300 in FIG. 4, the position may be changed according to a user's setting. For example, the reference point 320 may be positioned to the left side from the center of the image 300.

On the other hand, the controller 180 when the specific object is selected through the user input unit 130 or the touch screen 151 in the state that the objects 311 to 314 are displayed in the image 300, the memory 160 The locations of the objects corresponding to the selected object are searched based on the current region in the provided map data [S114]. At this time, the search radius can be set by the user.

That is, when the object is selected, the controller 180 searches for the positions of objects corresponding to the object located within a preset search radius based on the current region in the map data.

If there is no map including a preset search radius based on the current region in the map data, the controller 180 transmits the location information of the current region to an external server through the wireless communication unit 110. The map including the search radius may be received from an external server and updated in the map data.

In addition, the controller 180 may receive and display an image indicating the location of objects corresponding to the object located within a preset search radius based on the current region from the external server through the wireless communication unit 110.

Meanwhile, when the location of the objects located within the preset search radius based on the current region is found as described above, the controller 180 displays information indicating the location of the objects in the image 300 using augmented reality. [S115].

In this case, the information indicating the position of the object includes information indicating the distance between the current region and the object and the orientation of the object based on the current region, and is displayed at the corresponding position of the objects in the image 300. .

In addition, when a plurality of objects corresponding to the object are searched for in the map data, the controller 180 may preferentially display the position of the object located at the nearest distance based on the current region.

On the other hand, as shown in (a) of FIG. 5, for example, if the second object 312 representing the restaurant is selected from the objects 311 to 314, the controller 180, within the map data The location of the restaurants 410 and 420 corresponding to the second object 312 located within the preset search radius based on the current region is searched for, and as shown in FIG. The location of the searched restaurants 410 and 420 is displayed in the image 300.

That is, the user can see the locations of the restaurants 410 and 420 represented by the augmented reality technique in the image 300, and more realistically know the locations of the restaurants 410 and 420 based on the current region. will be.

Meanwhile, as shown in FIG. 6A, the controller 180 simultaneously or later selects a second object 312 representing a restaurant in the image 300 or in the image 300. When the east orientation 300E is selected, the locations of the restaurants 410 and 420 corresponding to the second object 312 located within the preset search radius based on the current region in the map data are retrieved. As shown in (b) of FIG. 1, only the location of the restaurant 410 located within the selected east bearing 300E may be displayed among the locations of the found restaurants 410 and 420.

In addition, as shown in FIG. 7A, when the second object 312 representing the restaurant is selected in the image 300, the controller 180 corresponds to the second object 312. When the search radius setting window 330 of the restaurants is displayed and the search radius 50M of the restaurants is set through the setting window 330, as shown in FIG. 7B, the set search radius 50M The location of the restaurant 410 located in the display may be displayed.

In this case, the setting window 330 may be displayed in a concentric shape that can be enlarged or reduced in the image 300.

In addition, as shown in FIG. 8A, the controller 180 indicates that the second object 312 representing the restaurant in the image 300 corresponds to the east orientation 300E in the image 300. When dragging and dropping to the region, the location of the restaurants 410 and 420 corresponding to the second object 312 located within the preset search radius based on the current region in the map data is searched, As shown in (b), only the locations of the restaurants 410 located in the east bearing 300E to which the second object 312 is dragged and dropped among the locations of the retrieved restaurants 410 and 420 may be displayed. Can be.

Meanwhile, as shown in (a) of FIG. 9, in the state where the restaurant 410 is displayed in the image 300 by the process of FIGS. 5 to 8, the controller 180 controls the restaurant 410. If is selected, the detailed information 411 corresponding to the restaurant 410 is searched for in the map data, and a part thereof is displayed. When the detailed information 411 is selected again, it is shown in FIG. 9B. As described above, the entire contents of the detail information 411 may be displayed.

If the detailed information of the restaurant 410 does not exist in the map data, the controller 180 accesses a web or external server through the wireless communication unit 110 to obtain detailed information of the restaurant 410. The detailed information of the obtained restaurant 410 may be updated and displayed on the map data.
