TECHNICAL FIELD [0001] The present invention relates to a terminal and a server having an advertisement content providing function using a QR code,

The present invention relates to a terminal and a server having a function of providing advertisement contents using a QR code and a method of controlling the operation thereof.

The QR code (QR code) is a two-dimensional bar code in the form of a matrix representing information in a monochrome lattice pattern. It is possible to overcome the capacity limitation of a bar code which has been widely used in the past and to store the character data in addition to the numerical value with the two-dimensional bar code having the format and contents extended. A general bar code can store numerical or character information in one direction, that is, one-dimensional, whereas QR code has a two-dimensional shape in a vertical and horizontal direction, and can have more information. In addition to numerals, alphanumeric characters and character data can be stored.

With the spread of smartphones and the advantage that QR codes can contain more information than barcodes, ad technologies using QR codes have emerged. That is, when the user shoots the QR code containing the URL of the advertisement content through the smartphone, the smartphone recognizes the captured QR code, extracts the URL, and redirects the URL to the URL through the browser. Accordingly, since the smartphone receives and plays the corresponding advertisement content from the server, the advertiser can easily expose the advertisement content to the user.

However, there are some limitations in using QR codes in the conventional advertisement technology. From a technical point of view, QR codes can not display variable information, and the amount of information that can be contained in QR codes is limited. As a result, in the conventional advertisement technology, the QR code shows additional information in a manner of redirecting to a specific web page, and thus performs only the role of a gateway.

In addition, the communication unit 230 according to an embodiment of the present invention can transmit the confirmed advertisement contents to the terminal 100. [

Figure 4 - Overall conceptual diagram

4 is a conceptual diagram illustrating a content providing process according to an embodiment disclosed herein.

First, the server 200 sets a plurality of advertisement areas in the QR code based on the range of the context. For example, the server 200 sets a plurality of advertisement areas on a three-dimensional space composed of a first context (x axis), a second context (y axis), and a third context (z axis). The server 200 associates each of the plurality of set advertisement areas with at least one advertisement content and stores the association in the database 300. [ The advertisement content corresponding to the specific context (x1, y1, z1) is determined by the association.

A plurality of advertisement areas may be formed on the n-dimensional space according to the number of contexts. Thereafter, the server 200 confirms the advertisement area corresponding to the received context on the basis of the context received from the terminal 100, and transmits the advertisement content corresponding to the confirmed advertisement area to the terminal 100.

The terminal 100 may execute a QR code recognition application according to a user input. The QR code recognition application may be a dedicated application for receiving content according to the embodiment disclosed herein or a general application including a general QR code recognition function. First, a case where the terminal 100 executes a dedicated application will be described.

When the dedicated application is executed, the terminal 100 activates the camera of the A / V input unit 120. Accordingly, the user can photograph the QR code 500 displayed on the object through the camera. The terminal 100 may provide a preview function of the QR code 500 and a guide function for accurately photographing the QR code 500 while the QR code 500 is being photographed.

When the shooting of the QR code 500 is completed, the terminal 100 recognizes the QR code 500 and extracts a URL (Uniform Resource Location) for requesting the content from the QR code 500. In addition, the terminal 100 collects the context. The context may include at least one of current time, location, sound, illuminance, tilt, shake, temperature, and wireless sensitivity.

When the collection of the context is completed, the terminal 100 transmits a message requesting the advertisement contents to the server 200 via the network. The message requesting the advertisement contents may include the URL extracted from the QR code and the collected context. In this case, the terminal 100 combines the URL and the collected context and transmits it to the server 200 in a GET or POST manner. However, depending on the settings of the terminal 100 (e.g., when context collection is intentionally disabled) or the environment (e.g., if the location can not be measured) It may not be included.

When the server 200 receives the advertisement content request message from the terminal 100, the server 200 transmits the requested content to the terminal 100 in response thereto. At this time, the server 200 analyzes the received message and confirms whether or not the context necessary for providing the advertisement content can be confirmed from the message.

When the context necessary for providing the advertisement content can be confirmed, for example, when the message includes the context, the server 200 refers to the URL and the context included in the message and confirms the corresponding content in the database 300 And transmits it to the terminal 100.

However, if the context required to provide the advertisement content can not be confirmed, for example, if the message does not include the context, the server 200 requests the estimator 400 the context necessary to provide the advertisement content. The server 200 requests the estimator 400 for another context necessary for providing the advertisement contents, based on the first and second contexts received from the terminal 100, for example. The estimator 400 refers to the advertisement content request history of the terminal 100 stored in the database 300 and calculates the time at which the request for the advertisement content is received from the terminal 100 and the IP Protocol based location information and estimates the context not specified in the message. The estimator 400 transmits the acquired context to the server 200. [

The server 200 refers to the URL included in the message and the context acquired from the estimator 400 to check the corresponding advertisement contents in the database 300 and transmits the same to the terminal 100. [

The terminal 100 receives the advertisement contents from the server 200, displays the advertisement contents on the QR code 500 or displays the advertisement contents around the QR code 500. The ad content may include three-dimensional objects and motion data. In addition, the advertisement contents may include multi-view images. For example, when the user moves the terminal 100, the terminal 100 can determine the viewpoint by determining the location and angle of the terminal 100, and display the advertisement content at the determined point in time.

The terminal 100 receiving the advertisement content may store the gyro value at the time of recognizing the QR code 500 and may determine the position on the screen of the advertisement content thereafter based on the stored gyro value. For example, if the QR code 500 is displayed in the angle of view of the camera of the AV input unit 120 due to the movement of the terminal 100 while displaying the advertisement contents received from the server 200 in the terminal 100, The terminal 100 can determine the location of the QR code 500 using the previously stored gyro value.

When the terminal 100 executes the general application, the server 200 transmits the installation URL of the application that can reproduce the advertisement content to the terminal 100 instead of the advertisement content. In addition, the server 200 may provide the terminal 100 with a two-dimensional advertisement content preview image.

The terminal 100 displays a preview image of an advertisement content received from the server 200 and provides a menu for redirection to an installation URL. When the provided menu is selected, the terminal 100 redirects to the installation URL, downloads the application capable of playing the advertisement content, and installs the downloaded application. When the installation is completed, the terminal 100 requests the server 200 for advertisement contents, and the server 200 transmits the requested advertisement contents to the terminal 100. The terminal 100 reproduces the advertisement contents through the installed application.

In one embodiment, the QR code may include path information (including host information) in the form of a URL reflecting identification information of the QR code. In this case, the terminal 100 recognizes the QR code and can add the collected context to the acquired route information in the form of parameters. For example, when the URL included in the QR code includes the path of "http://www.xxx/xxx.QAR ", and the context information of the A time, B position, and C noise is collected, quot; http://www.xxx/xxx.QAR?time=A&position=B&noise=C&quot ;, and transmits the combination of the contexts corresponding to the advertisement area to the server 200 in a query form.

Alternatively, the terminal 100 may change the URL based on the context and transmit it to the server. For example, when the QR code includes URL1, URL2 and URL3, the terminal 100 can select any of URL1, URL2 and URL3 according to the value of the context. For example, URL1 may be selected in the time, position, and noise corresponding to the first range, and URL2 may be selected in the time, position, and noise corresponding to the second range. The criteria for selecting the URL may be included in the QR code or may be stored in either the terminal 100 or the server 200. The terminal 100 can transmit the selected URL to the server 200 and receive and reproduce the advertisement content from the server 200. [

In addition, the QR code may include information about a parameter, for example, a context type, necessary for the terminal 100 to receive the advertisement contents using the QR code. In this case, the terminal 100 may collect the context corresponding to the context type specified in the QR code, and transmit the collected context to the server 200. For example, the QR code may include a URL of "http://www.xxx/xxx.QAR" and parameter values of TIME, POSTION, NOISE.

In addition, the QR code may include a plurality of URLs and information corresponding to the respective conditions, for example, the context range. In this case, the terminal 100 can refer to the context range specified in the QR code, select the URL corresponding to the currently collected context, and transmit it to the server 200. [ For example, the QR code is "if TIME is between 09:00 and 18:00 then redirect to http://www.xxx/xxx1.QAR" and "then then redirect to http://www.xxx/xxx2. Quot; QAR ".

Referring to FIG. 5, the terminal 100 captures a real object (S110). The terminal 100 can photograph the real object while moving at various angles by the user. In this case, the terminal 100 can acquire position information, tilt information, shooting time information, and the like at the time of shooting the real object by using the built-in GPS, accelerometer, gyro sensor,

Referring to FIG. 6, the terminal 100 can photograph a real object 600 at various positions and angles. The position and angle at this time are stored together with the photographed image, so that this information can be used later to create the virtual object.

Referring again to FIG. 5, the terminal 100 streams an image file generated by shooting a real object (S120). The image file includes metadata and a body. The metadata includes positional information, tilt information, photographing time information, and the like obtained through the various sensors described above, and the body includes an actual image.

The terminal 100 monitors whether an input for registering an object is received (S130). When the shooting of the real object is completed, the user can apply the registration command of the object to the terminal 100. [

When an input for registering an object is received, the terminal 100 generates a virtual object (S140). The identification information, the name, the description, and the like of the virtual object are registered.

When the virtual object is created, the terminal 100 registers the virtual object file and the motion data using the streamed image file (S150). In this process, the virtual object file can be matched with the position information, the tilt information, and the shooting time information. Also, the motion data can be created and registered according to user input using the generated virtual object.

The terminal 100 can specify the context range of the generated virtual object (S160). The context range may mean a specific time, a specific location, a specific temperature, etc., at which the virtual object can be exposed. Thereafter, the virtual object can be exposed only at a specified time, position, temperature, and the like.

The terminal 100 generates the URL of the virtual object file and the QR code (S170). The terminal 100 can first generate the URL of the virtual object file and insert the generated URL into the QR code. The QR code can be printed and placed on a realistic object.

7A to 7D, the terminal 100 provides an interface for generating a QR code. Referring to FIG. 7A, the terminal 100 provides an interface for selecting a virtual object file to be used as advertisement contents. The user can select one of the streamed image files by shooting the real object.

Referring to FIG. 7 (b), the terminal 100 displays the virtual object 600 on the screen using the selected image file. Here, the user can further input the motion data of the virtual object 600.

Referring to FIG. 7 (c), the terminal 100 can generate a URL of the virtual object 600. For example, the terminal 100 may generate the URL of the virtual object 600 according to a predetermined rule.

Referring to FIG. 7 (d), the terminal 100 can generate a QR code using the generated URL. The terminal 100 may display an image corresponding to the generated QR code.

As described above, the terminal 100 may perform the operations required for the content registration process described with reference to FIGS. 5 to 7, but in the alternative, a separate content registration apparatus (not shown) The operation may be performed instead. In this case, the separate content registration device connected to the server 200 may be, for example, a console for managing the server 200, and a user interface device connected to the server 200 via a network.

8 to 12 - Contents receiving process

8 to 12 are views for explaining a process of receiving advertisement contents of the terminal 100 according to the embodiment disclosed herein.

FIG. 8 is a flowchart illustrating a process of receiving advertisement contents of the terminal 100 according to an embodiment disclosed herein.

The terminal 100 may execute an application providing a QR code recognition function (S210). As described above, the application providing the QR code recognition function can be a general application providing general QR code recognition function, that is, a function of redirecting to a URL corresponding to the QR code, or a dedicated QR code recognition function, The application may be a dedicated application that provides the function of receiving the advertisement content using the combination information of the URL and the context corresponding to the URL. First, a case of a dedicated application will be described.

When the application is executed, the camera of the A / V input unit 120 is activated, and the terminal 100 captures and recognizes the QR code by positioning the terminal 100 in the QR code displayed on the object according to the guide information (S220).

The terminal 100 determines whether the current mode is set to the context mode (S230). The current mode can be set to the context mode or the normal mode.

If the current mode is the context mode, the terminal 100 extracts the URL from the QR code and collects the context (S242). Then, the terminal 100 combines the extracted URL and the collected context (S244), and transmits a message requesting the advertisement contents to the server 200 using the combined information.

If the current mode is not the context mode, the terminal 100 extracts the URL from the QR code (S252). Then, the terminal 100 transmits a message requesting the advertisement contents to the server 200 using the extracted URL (S254).

The terminal 100 receives the requested advertisement content from the server 200 (S260), and can reproduce the received advertisement content (S270).

When the current mode is the context mode, the terminal 100 can receive different advertisement contents according to time, position, temperature, and the like with respect to one URL inserted in the QR code.

For example, when a user shoots a QR code on a billboard through a terminal in an area A, a 3D laptop advertisement is played back over the billboard, and when a QR code is photographed on the billboard through a terminal in area B, A three-dimensional automobile advertisement can be reproduced on the billboard.

In addition, when the user prints out a QR code on a business card and provides it to the other party, as the other person shoots the QR code through the terminal 100, a goods are reproduced in a three-dimensional form superimposed on the business card in the city center, As the product is reproduced in a three-dimensional form superimposed on the business card, it becomes possible to promote the product related to the residence area, the office area, etc. with the user's single business card.

In addition, when a user intends to promote his / her product in an exhibition, if a QR code is arranged in a specific space provided in an exhibition hall booth, the visitor can move his / her terminal 100 and enjoy the three- .

In addition, when the user shoots a specific QR code through the terminal 100 in a noisy automobile, a three-dimensional model of the sleeping lid and the ear plug is displayed. If the surroundings are quiet, the same QR code is photographed, And can be displayed in a three-dimensional form.

9 is a diagram for explaining an application providing a QR code recognition function according to an embodiment disclosed herein.

As shown in the left side of FIG. 9, an application providing a dedicated QR code recognition function can recognize that the terminal 100 has responded to the QR code 500 by photographing and recognizing the QR code 500 displayed on the object 700 The advertisement contents including the virtual object 600 of the real object 700 or the QR code 500 can be received from the server 200 and displayed in a superimposed manner on the real object 700 or the QR code 500. [ In this case, when the terminal 100 receives an input for storing the advertisement content, it can store the advertisement content, and can then play back the selected advertisement content by calling a list of the stored advertisement contents.

As shown in the right side of Fig. 9, when the terminal 100 captures and recognizes the QR code 500 displayed on the object 700, the application providing the general QR code recognizing function responds to the QR code 500 A URL for downloading a two-dimensional image of a virtual object 600 and an application providing a dedicated QR code recognition function can be received from the server 200 and displayed. In this case, when the terminal 100 receives an input for downloading an application providing a dedicated QR code recognition function, the terminal 100 can download and install the application. When the application providing the dedicated QR code recognition function is executed, the process of receiving the advertisement content in the application providing the dedicated QR code recognition function described above proceeds.

In this case, the server 200 detects the user-agent of the browser and judges whether the application requesting the advertisement content is an application providing the dedicated QR code recognition function or an application providing the general QR code recognition function, The above process can be selectively performed according to the result. Here, the user-agent may contain information about the browser.

FIGS. 10A and 10B are views showing an advertisement content reproduction screen of the terminal 100 according to the embodiment disclosed herein.

10A, when the QR code 500 displayed on the object 700 is photographed using the camera of the AV input unit 120, the terminal 100 uses the QR code 500 and the context information at the shooting time And may receive advertisement content from the server 200. The terminal 100 may synthesize and display the received advertisement contents on the QR code 500. The advertisement contents may include a three-dimensional virtual object 600. In the case of a multi-point video, Can display different images for. When the user moves the terminal 100, the virtual object 600 can be moved and track the position of the QR code 500 on the screen according to the movement of the terminal 100, The position of the ad content can be corrected so that it can be continuously displayed on the code.

10B is a view showing an advertisement content playback screen of the terminal 100 according to the embodiment disclosed herein.

If the QR code 500 recognized by the terminal 100 does not include the identification information of the 3D advertisement content proposed in this specification, that is, even if the QR code 500 is the general QR code, Can be synthesized and displayed in three dimensions. For example, as shown in FIG. 10B, when the advertisement content associated with the general QR code includes a web page, the terminal 100 should display the web page in two dimensions, A web page is displayed on the front side and additional information related to the web page, for example, a web page meta tag, may be displayed on one side of the web page. However, the display method shown in FIG. 10B is merely an example. In the case of a general QR code, that is, a QR code not associated with the three-dimensional advertisement content proposed in the present specification, the terminal 100 displays the advertisement content in its original shape It can be displayed two-dimensionally.

11 is a conceptual diagram illustrating a context estimation process of the estimator 400 according to an embodiment disclosed herein.

The terminal 100 transmits to the server 200 a context collected through various sensors together with the URL extracted from the QR code in the context mode through the application having the dedicated QR code recognition function. However, when the terminal 100 can not collect the context, whether the user intentionally or intentionally, the terminal 100 can not provide the context to the server 200.

In this case, the server 200 requests the estimator 400 for the context of the terminal 100, and the estimator 400 analyzes the advertisement content request history stored in the database 300 to determine the context of the current terminal 100 And provides it to the server 200.

The estimator 400 may obtain the time at which the terminal 100 requests the advertisement content to the server 200 and the IP based location of the terminal 100 and predict the context corresponding to the acquired time and location. For example, if the noise is 5 at the first time and position at which the terminal 100 requested the advertisement contents in the past, 6 at the second time and position, and 7 at the third time and position, The noise corresponding to the current time and position in the middle of the 1 hour and the position, the second time and the position, the third time and the position can be estimated as an average value of 6 thereof. The estimator 400 transmits 6, which is an estimated value of noise, to the server 200, and the server 200 can transmit appropriate advertisement contents to the terminal 100 using this value.

12 is a flowchart illustrating a QR code position tracking process of the terminal 100 according to an embodiment disclosed herein.

The terminal 100 captures the QR code and stores the gyro value when the QR code is recognized using the gyro sensor (S221). The terminal 100 may send a message requesting the advertisement contents to the server 200 and the server 200 may transmit the requested advertisement contents to the terminal 100. [

The terminal 100 reproduces the advertisement content received from the server 200 and displays it on the screen. At this time, the terminal 100 can overlay the advertisement contents in the QR code using the augmented reality technique. While the advertisement content is being reproduced, the terminal 100 tracks the screen coordinates of the QR code corresponding to the location where the advertisement content is to be displayed (S271).

If the screen coordinate tracking of the QR code is successful in step 272, that is, if the QR code continues to exist in the screen in step 272, the terminal 100 detects the position of the QR code (S273) The relative position of the viewpoint is detected based on the ratio (S275), and the 3D virtual object corresponding to the advertisement content can be displayed as the detected position and the viewpoint (S276).

However, if it is determined in step 272 that the screen coordinate tracking of the QR code is failed, that is, if the QR code is out of the screen, the terminal 100 determines the position of the QR code based on the gyro value, (S275), and the 3D virtual object corresponding to the advertisement content can be displayed as the detected position and the viewpoint (S276).

According to the embodiment, when the QR code is out of the screen, the terminal 100 may output guide information indicating the position of the QR code.

13 - Content transmission process

13 is a flowchart showing a process of transmitting advertisement contents of the server 200 according to the embodiment disclosed herein.

The server 200 can set a plurality of advertisement areas in one QR code based on the range of the context (S310). For example, a plurality of advertisement areas may be set according to the time, the place, the noise, or a combination of the same QR codes.

The server 200 may associate each of the plurality of advertisement areas with at least one different advertisement content (S320). For example, from 9:00 am to 6:00 pm, the first ad content is associated with the QR code, and from 6:00 pm to the next morning at 9:00 am the second ad content may be associated.

The server 200 may receive a message requesting advertisement contents from the terminal 100 (S330). The message requesting the advertisement contents may include a URL inserted in the QR code and a context collected in the terminal 100. [

The server 200 determines whether the message received from the terminal 100 includes a context (S340). The server 200 confirms the URL received from the terminal 100 and the advertisement content corresponding to the context in step S360 and transmits the advertisement content to the terminal 100. [ (S370). For example, when a message received from the terminal 100 is included, the server 200 transmits the first advertisement content corresponding to 10:00 am to the terminal 100, , The server 200 transmits the second advertisement content corresponding to 10:00 PM to the terminal 100. [

Alternatively, if the context received from the terminal 100 is not included in the message, the server 200 requests the estimator 400 for the context of the terminal 100. [ The estimator 400 estimates the context of the terminal 100 and provides it to the server 200 in the manner described above. The server 200 determines an advertisement area corresponding to the URL received from the terminal 100 and an advertisement area corresponding to the context received from the estimator 400 in step S360 and confirms the advertisement content corresponding to the determined advertisement area in step S370, The advertisement content is transmitted to the advertisement server 100 (S380). For example, when a message is received from the terminal 100 at 10:00 am, the server 200 transmits the first advertisement content corresponding to 10:00 am to the terminal 100, and a message is received at 10:00 pm The server 200 transmits the second advertisement content corresponding to 10:00 PM to the terminal 100. [
