As described above, the touch input through the touch pad 135 has an advantage of preventing the virtual keypad 151c 'from being covered by the finger when touched, as compared with the touch input through the display unit 151. When the display unit 151 and the touch pad 135 are transparent, the fingers located at the rear of the terminal body can be visually checked, and thus more accurate touch input is possible.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This may be useful for editing an image displayed on the display unit 151.

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be activation or deactivation of the display unit 151 or the touch pad 135, for example.

For convenience of description, it is assumed that the mobile terminal mentioned below includes at least one of the components shown in FIG. 1.

The present invention allows the user of the mobile terminal 100 to leave a desired message content through the mobile terminal 100 with respect to a specific specific place or a specific object. The present invention may select a specific point on the touch screen 151 and leave a message for a specific place or a specific object corresponding to the specific point. In the following description, the present invention may be applied to a specific place or a specific object even if the description is limited to a specific place or a specific object for convenience of description.

4 is a flowchart illustrating a flow of a message generating method for an external object according to an embodiment of the present invention.

The camera module 121 of the mobile terminal 100 receives an image from the outside (S410). The location information module 115 obtains terminal location information (S420). The touch screen 151 displays the input image (S430). The touch screen 151 receives a touch operation for a specific point (S440). The touch screen 151 receives a message writing for the specific point (S450). The wireless communication unit 110 transmits a message to an external server (S460).

Hereinafter, a flow of a message generating method for an external object according to an embodiment of the present invention shown in FIG. 4 will be described.

The camera module 121 of the mobile terminal 100 receives an image from the outside (S410).

When the mobile terminal 100 enters the camera photographing mode or enters the augmented reality driving mode, the mobile terminal 100 may activate the camera 121 and receive an external image using the same. In this case, the camera photographing mode or the augmented reality driving mode may be entered when a corresponding menu item or a corresponding key (or key area) is selected. Furthermore, the camera may enter the augmented reality driving mode in a state in which the preview image input using the camera 121 is displayed in the camera photographing mode.

Here, augmented reality is a field of virtual reality, which is a computer graphics technique of synthesizing virtual objects in a real environment and making them look like objects existing in the original environment. Therefore, the mobile terminal 100 may display a virtual object or a virtual image on the image representing the real environment input through the camera 121 in the augmented reality driving mode.

The input image may be a preview image or may be a video photographed by the camera 121.

In addition, the input image may be zoomed in or zoomed out according to a user setting.

The mobile terminal 100 obtains the location information of the mobile terminal 100 using the location information module 115 (S420).

The mobile terminal 100 may obtain its current location information from the satellite using a global positioning system (GPS). For example, the location information may include the longitude, latitude, coordinate values, etc. of the point where the mobile terminal 100 is currently located.

Furthermore, the location information of the mobile terminal 100 may further include a direction in which the camera 121 of the mobile terminal 100 faces at a point where the mobile terminal 100 is currently located. The mobile terminal 100 may include a motion detection sensor and detect a direction in which the camera 121 faces by using the motion detection sensor. For example, the direction in which the camera 121 faces may be expressed by at least one of east, west, south, and north.

Next, the touch screen 151 displays the input image (S430).

In operation S410, an image input from the camera module 121 may include various images. The image may be a still image or a video. The input image may or may not include an object in the image. For example, an object such as a building may exist in the input image, while a specific object such as the sky or the sea may not exist. Here, the object may include a thing having address information (or location information) thereof, such as a building, a shopping mall, and a store, located within a certain distance from the mobile terminal 100.

The touch screen 151 may display the input image as it is input, but may be edited and displayed in an appropriate manner. For example, since the mobile terminal 100 of the present invention selects a specific point through the touch screen 151, a grid shape may be superimposed on an image so that the specific point can be easily selected. This allows the user to more easily select the desired point.

Object information about an object in the image may be obtained from the AR server. Accordingly, the object information received from the AR server through the wireless communication unit 110 may be included in the image. Accordingly, the touch screen 151 may not only display an input image but also display object information about an object in the image. Here, the object information is information about the object, and may include information such as the name of the object, the location of the object, the distance from the object, and the like.

Next, the touch screen 151 receives a touch operation for a specific point (S440).

The touch screen 151 not only displays an input image but also receives a touch operation for selecting a specific point of the touch screen 151.

The image of the touch screen 151 of the present invention may be enlarged or reduced. For example, when too many objects are included in an image displayed in the touch screen 151, a desired object may not be selected through the touch screen 151. Accordingly, the controller 151 may enlarge or reduce the input image or enlarge or reduce the image input by a user command through the user input unit 130.

Corresponding to a particular point of touch screen 151 may or may not be a particular object. Therefore, when the user touches a specific point on the touch screen 151, it may be seen that an object corresponding to the specific point is selected, but it may also be viewed as selecting a place corresponding to the specific point. Accordingly, whether to recognize the object as the object for a specific point selected in the image or the exact place for the specific point in the image may be determined according to the user's selection.

For example, when a car is moving in an image in the touch screen 151 and the user selects a specific point of the touch screen 151 corresponding to the car through a touch operation, the object is recognized as an object corresponding to the specific point. If set to, the object is selected even if the car, which is an object, moves. However, when it is set to recognize the correct place corresponding to a specific point, it is recognized as the place where the car at the time of the touch operation is placed, not the car.

5A is a diagram of selecting a specific point by directly touching an image displayed on the touch screen 151.

FIG. 5A (a) is a diagram illustrating touching a building which is an object among images displayed on the touch screen 151.

5A illustrates a case in which an object corresponding to a specific point selected by a touch operation exists. In the figure, there are buildings 512 and 514, cars 516 and people 518 as objects. A specific point of the touch screen 151 is selected through a user's touch operation, and the building 512 is selected as an object corresponding to the specific point.

5B illustrates another case in which an object corresponding to a specific point selected by the touch operation exists. In the figure, there are several objects. Unlike (a) of FIG. 5A, a person 518 is an object selected by a touch operation.

As a comparison of the cases of (a) and (b) of FIG. 5A, FIG. 5A illustrates a case in which a building is selected as a stationary object, and FIG. 5A illustrates a case in which a person is selected as a moving object. As such, the present invention can select both stationary or moving objects and leave several messages about them.

5A illustrates a case in which a specific part of an object is selected by a touch operation. In FIG. 5A (c), an image in the touch screen 151 displays a table as a still object. Compared with (a) of FIG. 5A, which selects a stationary object, if (A) of FIG. 5A has selected the entire object, FIG. 5A (C) has selected a specific portion of the object. In other words, the present invention may select a specific part of an object and leave a message for that part.

For example, if there is a messy trace on a portion of the table, it is more effective to leave a messy trace on that portion rather than leaving a message on the entire object. In the present invention, it is possible to select a part of the object corresponding to such a case and leave a message.

5B illustrates a case in which an object is directly searched and selected by a name.

The present invention may leave a message for the external object or place displayed through the touch screen 151 as well as the external object or place even though the touch screen 151 is not. In this case, instead of directly touching the image displayed on the touch screen 151, the external object or place may be directly input and selected.

5B illustrates the direct entry of an external object or place. The exact name of the object or place may be input through the user input unit 130 or the touch screen 151. The drawing illustrates selecting the object or place to leave a message through the correct name of '63 BUILDING '.

As such, an external object or place to leave a message is selected through a touch operation through the touch screen 151 or a direct input through the user input unit 131.

When it is confirmed that the external object or place is selected, the controller 180 obtains information on the selected external object or place.

The information on the object or place may include a name {for example, a point of interest (POI)) or a representative icon of the object or place, location information, and the like as identification information thereof.

On the other hand, the controller 180 can recognize the current location where the mobile terminal 100 is currently located by using the coordinate information of the obtained terminal location information, and the direction in which the camera 121 is facing among the obtained location information. The front of the mobile terminal 100 may be recognized at the current location. Accordingly, the controller 180 may obtain information on a plurality of objects or places located within a certain distance ahead of the mobile terminal 100.

Next, the touch screen 151 receives a message writing for the external object corresponding to the specific point (S450).

6A and 6B illustrate a method of generating a message for a selected external object in accordance with an embodiment of the present invention.

FIG. 6A illustrates a method of generating a message through various formats for the selected external object of the touch screen 151.

When a specific external object is selected, there are various types of messages left for the external object. For example, it may include a text message, a memo, an MP3, an album photo, and the like. In FIG. 6A, when a external object is selected, a message menu is displayed for a building corresponding to the external object. Accordingly, the user of the mobile terminal 100 can select a format that he wants to leave through the corresponding message menu.

FIG. 6B is a diagram illustrating a method of actually inputting a message for a selected specific point.

FIG. 6B (a) is a diagram illustrating leaving a message to a specific person in a message format. When a text message is selected as the message format for the selected object 512. When the message format is selected, the message window 610 allows the user to record specific message contents. In the figure, message content for a particular person is included in the message window 610.

(B) of FIG. 6B is a diagram illustrating leaving a message in a memo format. The message left for a particular place or object may be left for the user of the mobile terminal 100 to view. For example, leaving a memo through an item such as a post-it and leaving it at a particular place may be for the user himself.

FIG. 6B (b) is for this case, and illustrates creating a message for a specific place in a memo format. However, in the case of the memo format, whether the user of the mobile terminal 100 can read only or can be read by everyone is determined according to the selection.

Fig. 6B (c) is a diagram showing a message in an image format. It is an effective method to leave not only a text format but also an image format in a record left for a specific place. Accordingly, a message may be left using an image previously stored in the terminal 100 in an image format.

As described above, a written message can be set to be read only by a specific person. For example, the recipient may be set as information attached to the message, and the message may be set to be sent only to the recipient. Alternatively, a password may be assigned to the message so that the message can be read only by a specific person.

The above-described message may be a multimedia message service (MMS) message, a short message service (SMS), an instant message service (IMS).

Next, the wireless communication unit 110 transmits a message to the external server (S460).

7 is a diagram illustrating a method of transmitting a message created in accordance with an embodiment of the present invention.

7 (a) is a diagram illustrating registering a created message with an AR server.

Since the written message is a written message for a specific place or a specific object, it may be sent to the AR server and stored in the AR server. Accordingly, the stored message may transmit the message when a specific terminal near the location requests the AR server for location information and the like. Alternatively, when there is a specific terminal near the corresponding location for a message stored or registered in the AR server, the message may be transmitted regardless of the request of the specific terminal.

FIG. 7B is a diagram illustrating registering a created message with a social network service (SNS) server.

The mobile terminal 100 of the present invention may register a message generated for a specific object in the SNS server. The generated message for a specific object includes information about the specific object and the message content. Messages with this information can be registered on SNS servers such as Facebook and Twitter.

7 (c) is a diagram illustrating directly sending a created message to another terminal.

The mobile terminal 100 of the present invention does not necessarily transmit a message generated for a specific point to an external server. Instead, the mobile terminal 100 may store the generated message in the memory 160 of the mobile terminal 100. When the message generated for the specific point is a message designating the receiving terminal, the message may be directly transmitted to the receiving terminal when the receiving terminal is located near the specific point.

8 is a diagram illustrating a method of displaying a message created in accordance with an embodiment of the present invention.

FIG. 8A is a diagram of displaying the format and number of messages created for a specific object on the touch screen 151.

Not only the other terminal but also the mobile terminal 100 that composes the message may check the created message through the touch screen 151 of the mobile terminal 100. The figure displays the created message on the touch screen 151. It is displayed via the touch screen 151 that one text message and two notes have been created and sent for the particular object 712.

FIG. 8B is a diagram for displaying related contents when a written message is confirmed by another person.

According to the present invention, when a user of a mobile terminal 100 transmits a message to a specific object and transmits the message to an external server, the mobile terminal 100 may check the message when the message is viewed or transmitted by another terminal. For example, it is possible to see on the touch screen 151 who, when, and when the message was confirmed. 8 (b) displays the contents of the message viewing on the touch screen 151 through the confirmation message 820.

Hereinafter, a method of obtaining a message for an external object according to another embodiment of the present invention will be described.

The mobile terminal 100 of the present invention may generate a message for a specific external object or a specific place. In addition, the mobile terminal 100 of the present invention may obtain a message generated for a specific external object or a specific place generated by another terminal.

While the above description relates to a method for generating a message for a specific point, which is an embodiment of the present invention, the following description relates to a method for obtaining a message for a specific point.

9 is a flowchart illustrating a method of obtaining a message for an external object according to another embodiment of the present invention.

The camera module 121 of the mobile terminal 100 receives an image from the outside (S910). The location information module 115 of the mobile terminal 100 obtains terminal location information (S920). The controller 180 determines whether a message exists for a specific point (S930). The wireless communication unit 110 receives a message for a specific point (S940). The touch screen 151 displays the received message (S950).

Hereinafter, the present invention will be described according to the flow of the message obtaining method for the external object illustrated in FIG. 9.

The camera module 121 of the mobile terminal 100 receives an image from the outside (S910).

Similar to the message generation method for the external object described above, the camera module 121 receives an image from the outside. When the mobile terminal 100 enters the camera photographing mode or enters the augmented reality driving mode, the mobile terminal 100 may activate the camera 121 and receive an external image using the same.

Next, the location information module 115 of the mobile terminal 100 obtains terminal location information (S920).

The mobile terminal 100 obtains its current location information from the satellite using GPS. For example, the location information may include the longitude, latitude, coordinate values, etc. of the point where the mobile terminal 100 is currently located. The location information of the mobile terminal 100 may further include a direction in which the camera 121 of the mobile terminal 100 faces at a point where the mobile terminal 100 is currently located.

Next, the controller 180 determines whether a message exists for a specific point (S930).

The controller 180 determines whether there is a message for a specific object in the image of the mobile terminal 100 by using the terminal location information obtained in operation S920. In this case, the presence of a message may be visually determined in relation to the points in the image input in step S910. The presence of the message may be confirmed from the AR server, the presence of a message transmitted from another terminal, or may be confirmed through the existence of a message registered in the SNS server.

Meanwhile, the camera module is operated through steps S910 and S920, and the mobile terminal 100 obtains terminal location information. Here, the present invention does not necessarily operate the camera module 121 to receive an image from the outside. Instead, when the mobile terminal 100 of the present invention is located near a specific point where the message exists, the alarm function may confirm the existence of the message. Accordingly, the present invention may confirm the presence of a message even without executing the AR function or operating the camera module.

Next, the wireless communication unit 110 receives a message for a specific object (S940).

FIG. 10 is a diagram illustrating a method of displaying a presence upon receipt of a message according to another embodiment of the present invention.

10 (a) is a diagram for displaying a message confirmation window when the existence of a message is confirmed.

As a result of the controller 180 determining the existence of the message, when the presence of the message is confirmed, the touch screen 151 may display a message confirmation window 1010 indicating the existence of the message. The message confirmation window 1010 may be displayed when the existence of the message is confirmed while displaying the external image by operating the AR function or operating the camera module 121. Alternatively, even when the mobile terminal 100 does not operate a special function, such a message confirmation window may be generated and displayed when the mobile terminal 100 is located at a corresponding position where a message is created. Meanwhile, when the message is generated for the mobile object, when the mobile object is located near the mobile terminal 100, the message confirmation window may be generated and displayed.

FIG. 10B is a diagram for displaying on the touch screen 151 information related to the presence of a message written for a particular point.

When the controller 180 determines that a message written for a specific point exists, the touch screen 151 may display the message for an image input from the outside. In the figure, objects 1032, 1034, 1036 are displayed as being present in the image. A message has been identified for a particular building 1032 of the objects, and information about this message is displayed through the particular window 1020. As the information on the message, the generation time of the message, the creator of the message, and the type of the message may be displayed.

FIG. 10 (c) is a diagram displaying receiving a message written for a specific point.

When the mobile terminal 100 confirms the existence of a message written for a specific object, the mobile terminal 100 may receive the message. The message can be received in various ways. The wireless communication unit 110 may receive a corresponding message from an external server, may directly receive the message from another terminal that composes the message, or may receive a message from an SNS server.

Next, the touch screen 151 displays the received message (S950).

11 is a diagram illustrating a method of confirming a received message according to another embodiment of the present invention.

The message generated for a specific point may be displayed to reflect the situation at the time of creation. For example, in the case of a message written for a stationary object, a message may be displayed for a stationary object, and in the case of a message written for a moving object, a message may be displayed for a moving object.

11 (a) is a diagram illustrating displaying a message for a building that is a stationary object. It is a case where a specific building exists in the touch screen 151 and it is determined that a message is generated for the building. Accordingly, the touch screen 151 displays the message content of the building in the message window 1110.

11 (b) is a diagram illustrating displaying a message for a person who is a moving object. The controller 180 determines that a specific person exists on the touch screen 151 and a message is generated for the specific person. In this case, it is recognized that a message exists for the person, and according to the movement of the person, the message window 1120 may also be displayed as moving together.

11 (c) is a diagram illustrating displaying a message for a specific part of an object. As described above, a message may be written for the entire object, but a message may be written for some of the objects. Accordingly, when confirming the existence of a message written for a part of the object, the touch screen 151 may display the message through the message window 1130 for the part of the object.

The mobile terminal 100 of the present invention may check the message and may create a reply message for the message.

12 is a diagram illustrating a method of generating a reply message for a received message according to another embodiment of the present invention.

12 (a) is a diagram for selecting a reply menu for creating a reply message for the confirmed message.

The mobile terminal 100 may not only check a message for a specific point, but may also create a reply message for the corresponding message. In this case, the message generation method for the external object described above may be used. By selecting the reply menu, you can create a message for a specific point.

Fig. 12B is a diagram for creating a reply menu for the confirmed message.

The touch screen 151 displays a QWERTY key region 1222 and a message composition window 1220, so that a reply message can be written.

The created reply message is a message created for a specific object and may be sent back to an external server or an SNS server as a message for the same object.

12 (c) is a diagram illustrating displaying a generated reply message.

There are a variety of ways to display reply messages. You can also display the existence of the first message or reply message through a specific list window.

In the figure, the association between the reply message and the original message is displayed via an arrow. Initial message 1232 is written for building 1232 and displayed as displayed for that building 1232. The reply message 1234 is also displayed as being displayed for the building 1232 and being displayed for the original message 1232 as a reply format in the original message 1232.

12 (d) is a diagram illustrating displaying a plurality of reply messages.

If there is more than one reply message, there is a need to clearly show which message the reply message is for. This may be indicated through a message list window, but in the figure it is indicated by an arrow.

In the figure, an initial message 1242 created for the first specific point is displayed for the building 1240. Replies messages 1244 and 1248 created for the original message 1242 are displayed for the original message 1242. An additional reply message is generated for the reply message 1244 of the reply messages 1244 and 1248. Accordingly, a reply message 1246 for the reply message 1244 is generated and shown as being displayed thereon. In this way, each reply message can be recognized as being associated with each other.

In this way, a reply message may be generated for a message generated for a specific point, and the relationship between the reply message and the related message may be variously displayed on the touch screen 151.

In addition, according to an embodiment of the present invention, the above-described method for generating and obtaining a message for an external object may be implemented as code that can be read by a processor in a medium in which a program is recorded.
