4 is a flowchart illustrating a flow of a method for displaying object information in accordance with the present invention.

Referring to FIG. 4, the object information display method will be described below.

The user input unit 130 receives search criterion information from the user (S410). The camera 121 receives an image from the outside (S420). The location information module 115 obtains terminal location information (S430). The controller 180 obtains a plurality of object information (S440). The controller 180 searches for object information satisfying the search criterion information (S450). The display unit 151 displays the retrieved object information or object (S460).

Hereinafter, the display method of the present invention will be described in detail with the flow of the flowchart of FIG. 4.

First, the user input unit 130 of the terminal 100 receives search reference information from the user (S410).

As used herein, 'search criterion information' is criterion information for classifying various pieces of information about a plurality of objects input from the outside.

When too much object information is displayed on the display unit 151 using Augmented Reality (AR), the user cannot find the desired object and object information among the many information. In addition, displaying the object information for all objects viewed through the camera 121 results in slowing down the performance speed of the terminal 100.

Accordingly, the present invention can be set so that the user inputs the search criteria information so that the user can search and display only the desired object and object information about the object.

FIG. 5 is a diagram illustrating a setting and a search method for search criterion information according to the present invention.

5A is a diagram for displaying a search criterion information setting screen.

The object desired by the user may be in various forms and various kinds. For example, the object that the user wants to acquire through the terminal 100 may be a person, a specific building, another terminal, or a specific animal. Since the object desired by the user is not limited to a specific form, the setting of the search criteria information may take various forms.

5A illustrates setting criteria in the search criteria information setting window 510 as an example of setting the search criteria information. A free search that allows the user to freely search for an object that the user wants, and a category-specific search that subdivides the object that the user wants by category are displayed as an example of setting the search criterion information in the search criteria information sublingual window 510.

FIG. 5B is a diagram showing a search for search of the search criteria information by free search. The user may directly input desired information through the user input unit 520. In the drawing, search reference information is input to a touch screen in which the display unit 151 and the user input unit 520 are coupled through a user's touch operation. When the user knows exactly the desired object and information about the object, the user can accurately obtain the information through free search.

FIG. 5C is a diagram illustrating a search for search criterion information by telephone number search. Various object information retrieved through the AR function may be about a person or a building. In many cases, since the object information includes a phone number associated with the object, using the phone number as the search criterion information may be one method of obtaining desired object information more easily.

FIG. 5D is a diagram showing searching for search criteria information by type. If the type of object desired by the user is specified but the exact name is not known, the search function by type can be used. The display unit 151 may display various types through the type search window 540. Various object information searched through it may be classified by type to obtain desired object information.

Searching by type is effective when the user does not know exactly which object they want to find. For example, if the user wants to find a nearby restaurant, the exact name or telephone number of the nearby restaurant where the terminal 100 is located may not be known. In this case, when the corresponding restaurant is selected as the search reference information by using the search function by type, the object information on the restaurant among the objects in the image can be easily obtained.

In a next step, the camera 121 of the mobile terminal 100 receives an image from the outside (S420).

When the mobile terminal 100 enters a camera photographing mode or enters an augmented reality operation mode, the mobile terminal 100 receives an external image by activating the camera 121. 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.

As used herein, the term augmented reality is a field of virtual reality, and 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.

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

The mobile terminal 100 obtains location information of the mobile terminal 100 using the location information module 115 (S430).

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 sensor (not shown), and may sense a direction in which the camera 121 faces by using the motion sensor.

In a next step, the mobile terminal 100 obtains object information of each of a plurality of objects located within a predetermined distance from the mobile terminal 100 based on the obtained position information under the control of the controller 180 (S440). ).

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. In addition, the object information may include all information related to the object as identification information on the object. The object information may include a name of the object {eg, a point of interest (POI)} or a representative icon of the object, a distance between the object and the terminal 100, and the like. In addition, object information may exist only for some of all objects located within a certain distance from the mobile terminal 100.

More specifically, the controller 180 may recognize a location at which the mobile terminal 100 is currently located by using coordinate information among the obtained location information, and the direction in which the camera 121 is facing among the obtained location information. The front of the mobile terminal 100 can be recognized using the current location. Therefore, the controller 180 may obtain object information of each of the plurality of objects located within a predetermined distance from the mobile terminal 100.

The obtaining step (S440) of the object information will be described in more detail below.

First, the mobile terminal 100 pre-stores object information for each object in the memory 160, and under the control of the controller 180, the object of each of the plurality of objects from the object information for each object previously stored in the memory 160. You can search for information. In this case, the memory 160 may store location information of the object having the object information together with the object information.

More specifically, the controller 180 may search the memory 160 for a plurality of objects having location information within a predetermined distance from the mobile terminal 100 and object information designated for each of the plurality of objects. Accordingly, the controller 180 may obtain object information of each of the plurality of objects within a predetermined distance from the mobile terminal 100 by searching for object information for each object stored in the memory 160.

Furthermore, object information and location information for each object previously stored in the memory 160 may be received from an external server or stored by default by a manufacturer when producing a terminal. In addition, object information and location information for each object previously stored in the memory 160 may be updated periodically or at any time.

Next, the mobile terminal 100 may receive object information of each of a plurality of objects located within a predetermined distance from the mobile terminal 100 from an external server through the wireless communication unit 110.

More specifically, the mobile terminal 100 transmits a signal for requesting object information of each of a plurality of objects located within a predetermined distance from the mobile terminal 100 to the external server, and thus, the front predetermined distance from the mobile terminal 100. The object information of each of a plurality of objects located within can be received.

In this case, the request signal may include location information of each of the plurality of objects, or may include a predetermined distance for displaying the location information and the object information of the mobile terminal 100.

In the former case, the mobile terminal 100 may receive object information corresponding to the location information included in the request signal from an external server. In the latter case, the mobile terminal 100 may receive object information of each of a plurality of objects located within a predetermined distance from the current position of the mobile terminal 100 from an external server.

The object information may be displayed in association with an object image corresponding to the corresponding object in the input image.

Even when the object image corresponding to the object information does not exist in the input image, the object information may be displayed at a position where the corresponding object image is predicted to exist in the input image.

The object information acquisition step S440 will be described with reference to FIG. 6.

6 is a diagram for displaying object information using an AR function according to the present invention.

FIG. 6A is a diagram of displaying an external image input through the camera 121. As shown in the display unit 151 in which the AR function is not executed, a plurality of objects in the image are displayed, but object information on the object is not displayed.

FIG. 6B is a diagram of displaying a plurality of objects and object information obtained through an AR function. FIG. 1 is a diagram illustrating object information of a plurality of objects in an input image using location information of the terminal 100. As described above, the object information may include various information about the object. In the figure, the objects in the image are shown buildings, buses, taxis, etc., and object information is displayed with the distance to the terminal 100, the bus number, and the like.

In FIG. 6B, various object information is displayed as the search criterion information input in step S410 is not applied. That is, it shows that all the objects and object information obtained by the controller 180 is displayed.

In a next step, the controller 180 searches for object information meeting the search criteria information (S450).

In operation S450, the controller 180 obtains various object information. Among the object information, the object information satisfying the search criterion information is searched using the search criterion information input in step S410.

The controller 180 compares the object information about the object or the object with the search criterion information, determines whether the object is satisfied, and searches for the object information. The controller 180 first analyzes all object information about objects in the image. When the search criterion information input by the user is compared based on the analyzed result and the degree of satisfaction of the predetermined level or more is displayed, the controller 180 determines that the object is an object that satisfies the search criterion information. The controller 180 repeats this process and searches whether the plurality of objects satisfy the search criterion information.

The degree of satisfying the search criterion information may vary. For example, when the search criterion information is set in proximity to the terminal 100, various objects located near the terminal 100 will be searched. However, there is a difference in proximity to the terminal 100 among various objects, and accordingly, there will be various degrees of satisfying the proximity, which is search criterion information.

In a next step, the display unit 151 displays the retrieved object information or object (S460).

There are various ways of displaying an object that satisfies the search criteria information. The object display method is to display an object that satisfies the search criterion information normally and to process an area except the object in a different color, to display only an object that satisfies the search criterion information, and not to display an area except the object. A method of prominently displaying only objects satisfying the reference information, a method of displaying objects satisfying the search criterion information in 3D format, and the like. This method is exemplary, and a method of distinguishing and displaying an object satisfying the search criterion information from another object and another area is not limited to the format and is included in the scope of the present invention.

The object displayed on the display unit 151 may be an object that satisfies the search criteria information, or may be object information about the object. In addition, both the object and the object information may be displayed on the display unit 151.

The display unit 151 of the terminal 100 distinguishes and displays an object satisfying the search criterion information from other objects in the image. Since the object that satisfies the search criteria information is clearly displayed to the user, the manner of displaying the object is not limited to a specific manner.

FIG. 7A is a diagram for displaying an object or object information that satisfies search criterion information according to the present invention. FIG.

(A) of FIG. 7A is a diagram for displaying only objects that satisfy the search criterion information.

In the figure, an object 710 that is a building that satisfies the search criteria information is normally displayed to distinguish the object 710 from other areas. However, areas other than the object 710 are shaded and displayed. Accordingly, the user can clearly see that the object that satisfies the search criteria information is the building 710.

FIG. 7A (b) is a diagram displaying both an object and object information that satisfy the search criterion information.

In the drawing, the object 710 and the object information 720 meeting the search criteria information are displayed on the display unit 151. Areas other than object 710 and object information 720 are displayed to be shaded. When displayed in this manner, the user can clearly grasp the object 710 meeting the search criteria information and the object information 720 for the corresponding object.

7B is a diagram illustrating another example of displaying an object or object information that satisfies search criteria information.

FIG. 7B (a) is a diagram illustrating only an object or object information satisfying search criteria information. The display unit 151 may display only an object that satisfies the search criterion information so that the user can display the desired object more clearly. Images other than objects satisfying the search criterion information may not be displayed so that objects satisfying the search criterion information may be clearly identified.

FIG. 7B (b) is a diagram illustrating a method of displaying an object that satisfies the search criterion information with an arrow. Since the object information may include various information about the object, when displaying all the object information in the limited display area, all of the images input from the camera 121 may be covered. Accordingly, an object satisfying the search criterion information may be displayed by an arrow, and object information on the corresponding object may be displayed through a separate object information window 730.

FIG. 7B (c) is a diagram illustrating an object that satisfies the search criterion information in a numbered manner. Similar to the case of (b) of FIG. 7B, in order to prevent the external image from being blocked due to the object information, the object may be displayed using a number indicating the object. In relation to the number, object information corresponding to the object may be displayed in the lower area of the display unit 151.

There may be a plurality of objects that satisfy the search criterion information input by the user. In this case, all objects satisfying the search criterion information may be displayed or only objects having the highest degree of satisfaction of the search criterion information may be displayed according to the setting of the search criterion information.

The degree of satisfaction with the search criterion information may be determined in various ways. For example, when searching by setting the search criteria information as 'toilet', all objects corresponding to the toilet in the image may be searched. However, in the case of searching by setting the search criterion information as 'closest restroom', it is determined that the toilet that exists closest to the terminal 100 satisfies the search criterion information even if a plurality of restrooms exist in the image. Can be.

8A and 8B show two or more object information or objects obtained in connection with the present invention.

FIG. 8A (a) is a diagram illustrating a case where a search is performed by setting the search criteria information to 'restaurant'. In the case of searching by setting the search criterion information as 'restaurant', the controller 180 determines the surrounding objects by using the location information of the terminal 100 and obtains the corresponding object information. The controller 180 searches for object information corresponding to 'restaurant' using the object information of the corresponding object. As a result of the search, when there are objects belonging to the restaurant, the display unit 151 displays the corresponding objects and object information. In the drawing, a Chinese restaurant, a spaghetti shop, and a bakery corresponding to a restaurant are displayed by satisfying a 'restaurant' which is search criteria information.

FIG. 8A (b) is a diagram illustrating a case where a search is performed by setting the search criterion information as 'Chinese House' rather than a restaurant. Since the Chinese restaurant is a more detailed search criterion information than a restaurant, it is displayed that the number of objects satisfying the search criterion information is reduced as compared with FIG. 8A (a). Therefore, only the objects 812 and 818 that satisfy the search criterion information are displayed on the display unit 151.

FIG. 8A (c) is a diagram illustrating a case in which the search criteria information is further subdivided and set as the 'cheapest Chinese house' to search. This is a case where the search criteria information in the case of FIG. 8A (b) is further subdivided and set as the cheapest Chinese house instead of the Chinese house. Accordingly, in (b) of FIG. 8A, the controller 180 indicates that among the objects 812 and 818, which are determined to be Chinese restaurants, the most inexpensive object 812 satisfies the search criterion information. Judges and displays it on the display unit 151.

FIG. 8B is a diagram illustrating another manner of displaying an object that satisfies the search criteria information.

FIG. 8B (a) illustrates a case where the search is performed by setting the search criterion information to 'bus'. In the case of searching by setting the search criterion information to 'bus', the controller 180 determines a bus among neighboring objects by using the location information of the terminal 100. As a result of the search, when there are objects searched by the bus, the display unit 151 displays the corresponding objects and object information. In the drawing, bus 401, bus 822, bus 1000, 824, and bus 501 826 corresponding to the bus are displayed on the display unit 151.

FIG. 8B (b) is a diagram illustrating a case where the search is performed by setting the search criterion information to 'right traveling bus'. This is the case where the search criteria information is set only by the bus for the right-hand movement instead of setting the search criteria information by the bus. Since the right-bound bus is more refined search criterion information than the bus, it is displayed that the number of objects satisfying the search criterion information is reduced as compared with FIG. 8B (a). Therefore, only buses 822 and 826 which are objects that satisfy the search criterion information are displayed on the display unit 151.

In addition, the object information may provide more clear information to the user. As shown in the figure, even when the bus to the right to travel to display the expected time to move to the right as a user information, the user can more easily check the desired bus through the display unit 151.

FIG. 8B (c) is a diagram illustrating a case where the search criterion information is further subdivided and set as a 'fastest moving bus'. In the case of (b) of FIG. 8B, the search criteria information is further subdivided to set the fastest right-movement bus instead of the right-movement bus. Accordingly, in (b) of FIG. 8B, the controller 180 determines that the object 822 which is the fastest bus among the objects 822 and 826 determined as the bus has the highest degree of satisfaction for the search criterion information. It is determined and displayed on the display unit 151.

Although not illustrated in the drawing, in the case where a plurality of objects satisfying the search criteria information exist, the object information may include more detailed information. For example, when the search criteria information is set as a Chinese house, the displayed object information may include representative foods of each Chinese house, prices, and visit records of celebrities. In addition, when the search criteria information is set to the bus for the right-side bus, the displayed object information may include the time required in consideration of traffic conditions until the right-side bus, the number of passengers in the bus, and the like.

Although not shown in the drawing, the degree of satisfying the search criterion information may be displayed by numbers or figures for a plurality of objects satisfying the search criterion information. Accordingly, the user can select the user from among a plurality of objects satisfying the search criteria information.

9 is a diagram for displaying a selection for object information in connection with the present invention.

In the case of various objects or object information displayed through the present invention, when there is a selection operation for the corresponding object or object information, the corresponding information may be displayed in more detail. If both the object and the object information is displayed in the external image input through the camera 121, the corresponding object information is inevitably limited. Therefore, when selecting the corresponding object and the object information, the controller 180 controls the display unit 151 to display the object and the object information in more detail.

FIG. 9A is a diagram illustrating objects 912 to 918 displayed on the display unit 151 and selecting a specific object 912 among them.

FIG. 9B is a diagram illustrating displaying object information on a specific object in response to a user's action of selecting the specific object.

In the figure, the selected specific object 912 is a Chinese house. The object information about the Chinese restaurant may include a telephone number of a Chinese restaurant, a representative food, a trade name of a Chinese restaurant, and a price of food.

As an example, the present invention may be usefully used in a situation of searching for and selecting clothes desired by a user in a department store. For example, when a user inputs a 'jacket' at a department store store as search criterion information, the corresponding clothes can be easily identified. The controller 180 may acquire various object information in a department store and determine a 'jacket', which is search criteria information, among various pieces of information obtained, and display only the corresponding object separately from other objects. When the Jacket is Displayed When a corresponding jacket is selected through a touch operation, various object information about the jacket may be displayed. For example, other appearances, prices, manufacturers, etc. of the jacket may be displayed. In addition, it may be set to directly connect to the Internet shopping mall to purchase the jacket.

FIG. 10 is a diagram illustrating a case in which an object satisfying search criteria information is not visible in an image.

When the coffee shop is set as the search criterion information, this means that an object satisfying the search criterion information does not exist in the image viewed through the camera 121. When a satisfying object is displayed in the image, the object may be distinguished as described above. However, if an object does not exist as shown in the drawing, it may not be displayed. Accordingly, since the object cannot be directly displayed, the object information of the object can be displayed in the form of an arrow or the like. In the drawing, the object information 1010 for 'StarVox', which is an object that satisfies the search criterion information, may be displayed using an arrow.

In addition, according to an embodiment of the present invention, the above-described method for displaying object information may be embodied as processor readable codes on a medium in which a program is recorded. Examples of processor-readable media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and may be implemented in the form of a carrier wave (for example, transmission over the Internet). Include.

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
