The control unit 180 receives the point of interest information requested from the server 300 (S105). The server 300 analyzes the position and attitude information of the terminal (position and attitude of the camera) transmitted from the mobile terminal 100 and determines what the object (object) input through the camera 121 of the terminal is have.

The control unit 180 superimposes the received point information on the real image input through the camera 121 (S106). At this time, the control unit 180 superimposes and displays the point of interest information corresponding to each of the objects included in the real image on the corresponding object.

The method of displaying the point of interest information may be implemented in various forms. For example, as shown in FIG. 5 (a), the controller 180 of the mobile terminal 100 may display an outline of the object on the real image with respect to the object on which the point of interest information exists. Alternatively, the control unit 180 displays summary information on the point of interest information existing in the real image displayed on the display screen in one area of the display screen as shown in FIG. 5B. The summary information may be displayed in a pop-up form. In addition, the summary information may be a list of points of interest information provided from the server 300. If any one of the items is selected from the list, the control unit 180 can display an indicator icon (e.g., ☞) on the object corresponding to the selected item in the real image.

The controller 180 changes the position or the posture of the camera 121 and changes the image input through the camera 121 so that the object in which the point of interest information exists also changes. Accordingly, the control unit 180 can request the server 300 to inquire interest point information about the object included in the changed real image according to the change of the position or attitude of the camera 121, and receive the information.

6 is a view illustrating a process of storing information of a point of interest of a mobile terminal according to an embodiment of the present invention.

As shown in FIG. 6, when a specific object having interest point information is selected on the screen displaying the point of interest information, the control unit 180 displays interest point information on the specific object according to the selection command. For example, when a user touches a specific object having interest point information in a real image displayed on a display screen, the controller 180 senses the touch through the sensing unit 140. [ Then, the control unit 180 displays the point-of-interest information about the sensed object on the pop-up window. Here, the control unit 180 displays information related to the selected object such as a building name, a telephone number, an address, and the like.

When the user desires to store the displayed point of interest information, the user touches the storage icon of the pop-up window, and the controller 180 detects the touch of the user and stores the point of interest information of the selected specific object in the memory 160.

7 is a flowchart illustrating an information display method using an augmented reality of a mobile terminal according to an embodiment of the present invention.

4, the mobile terminal 100 requests the augmented reality service server 300 to receive point of interest information about an object included in a real image to be acquired in real time via the camera 121, and is provided to the augmented reality service server 300 . Then, the controller 180 displays the information provided from the server 300 on the real image. For example, the control unit 180 superimposes a building name provided from the server 300 on a specific building existing in the real image.

When the user inputs a search command during the augmented reality function execution, the controller 180 displays the search range setting screen on the display screen (S201). In other words, upon receiving a search request for data matching or related to the point of interest information from the user input unit 130 while superimposing the point of interest information on the real image, the control unit 180 displays the search range setting screen.

On the search range setting screen displayed on the display screen, the control unit 180 sets the search range according to the user input inputted from the user input unit 130 (S202). For example, the control unit 180 may select at least one of data types such as a telephone directory, a memo, a message, a schedule, and an e-mail according to user input.

When the search range setting is completed, the controller 180 searches the data matching the point of interest within the set search range. For example, when the search range is set as a memo, the controller 180 compares the point of interest information with the memo stored in the memory 160 to check whether there is a memo that matches the point of interest information.

The control unit 180 superimposes the searched result on the real image acquired through the camera 121 (S204). At this time, the control unit 180 can display the search result using the explanatory line. In addition, the control unit 180 may display a predetermined icon on the object of the real image corresponding to the retrieved result. The predetermined icon may be implemented as a graphic, a symbol, an image, or the like, and indicates that there is a search result in the object.

8 is an example of displaying information retrieved using an augmented reality of a mobile terminal according to an embodiment of the present invention.

First, the control unit 180 of the mobile terminal 100 operates the camera 121 and requests the server 300 for point of interest information about the object included in the real image input through the camera 121. [ The mobile terminal 100 receives the requested point of interest information transmitted from the server 300 through the wireless communication unit 110. The control unit 180 of the mobile terminal 100 superimposes the received point of interest information on the real image and displays the real image on the display screen.

When the user requests a search while displaying the point of interest information, the controller 180 outputs a setting screen to the display 151 for setting the search range (a). For example, if the search menu is selected by the user's menu operation while using the augmented reality function, the control unit 180 displays a setting screen for setting the search range.

On the search range setting screen, the control unit 180 sets the search range according to the user's selection. For example, when receiving the search request by the user while displaying the point of interest information, the control unit 180 displays a list of data types (e.g., telephone directory, message, scheduler, memo) As shown in FIG. When the 'phone number' is selected from the displayed list, the controller 180 displays a field list (eg, phone number, name, address, e-mail, etc.) of data stored in the phone book. In other words, the search range setting is a process of selecting an object to be compared with the point of interest information.

If the search range is set, the controller 180 determines whether there is data matching the received point of interest information within the set search range. For example, if the search range is set to the phone number of the phone book in the search range setting screen, the controller 180 compares the point of interest information and the phone number stored in the terminal. If there is a phone number that matches the point of interest information, the controller 180 displays the phone number in a virtual phone line displayed on the display screen (bubble) (c).

9 is an example of a menu related to an embodiment of the present invention in which a mobile terminal displays a menu that can be executed using information retrieved using an augmented reality.

If the user inputs a long touch to an object on which the point of interest information exists, while displaying the point of interest information about the object included in the real image, the controller 180 displays the point of interest information Search for matching data (a). Here, the search range can be set by the user in advance.

When the data search is completed, the controller 180 displays a list of actions that can be performed using the searched data (b). For example, when the search range is the telephone number portion, the control unit 180 compares the point of interest information with the information of the contact party stored in the telephone directory. As a result of the comparison, if there is information that partially coincides with the interest point information, the control unit 180 displays an operation (function) menu that can be performed using the contact information corresponding to the information. For example, when the contact information includes the telephone number and the home page address, the control unit 180 displays operations such as telephone connection, URL connection, and detailed information storage as a menu.

10 is an example in which the mobile terminal related to an embodiment of the present invention displays information retrieved using an augmented reality together with a function execution icon.

The mobile terminal 100 searches for data matching the point of interest information on the object included in the real image within a preset search range. When the search is completed, the control unit 180 superimposes the searched result on the real image. At this time, if the user selects a specific object having the search result among the objects in the real image, the control unit 180 of the mobile terminal 100 searches the search data matching the point of interest information of the selected object, As shown in FIG.

In addition, the control unit 180 displays the retrieved data and displays an action execution icon that can be performed using the data. For example, as shown in FIG. 10, a call and a message icon are arranged and displayed along with the searched telephone number. In addition, if there is SNS subscription information (ID, password) among the contact information of the searched contact, the controller 180 displays and displays icons for allowing the SNS site connection to be executed.

In addition to this, an operation that can be performed using the received point of interest information can be displayed as a menu item. It is possible to set the selected object as a start point or a destination as shown in the drawing. It also allows you to search for available transportation at that location.

In addition to the above-described method, if a user shakes the terminal for a predetermined time after selecting a specific object having search data matching the interest point information on the object among the objects included in the real image, the controller 180 adds the phone number It is possible to implement such that the call is attempted to the telephone number.

Here, a different indicator may be displayed to identify whether the point of interest information about the object included in the real image is present or whether there is data in the terminal matching the point of interest information.

In addition, although the present invention describes the display of information using the augmented reality on the preview screen of the camera, it is also applicable to the execution of other functions (video call, navigation, etc.) using the camera.
