FIG. 6 is a flowchart illustrating a method of controlling the mobile device shown in FIG. 5. Hereinafter, an operation sequence of a mobile device for providing a location-based audio service according to an embodiment of the present invention will be described with reference to FIG. 6 as follows. However, the flowchart shown in FIG. 6 is an embodiment for better understanding of the present invention, and in some cases, changing some order or deleting or adding some steps is included in the scope of the present invention.

First, although not shown in FIG. 6, it is assumed that an application for providing a location-based audio service is downloaded to a memory of a mobile device. When the associated application (App.) Is executed, a list for identifying audio data is displayed (S610). At this time, various solutions for identifying audio data are possible, and channel numbers assigned to each digital signage may be used, or location information, distance information, and altitude information may be used.

Furthermore, the mobile device is designed to calculate its location using a GPS sensor (S620) and change the list according to the location (S630). This will be described later in more detail with reference to FIG. 13.

When an ID (eg, channel number or location information) corresponding to specific audio data is selected on the list of step S610 or S630 (S640), the mobile device requests a request signal for requesting specific audio data. ) Is transmitted to an external server (S650).

The mobile device receives audio data mapped to the user's preferred digital signage (S660), processes the data in a processable format (S670), and outputs the corresponding audio data through the speaker or earphone of the mobile device. (S680).

According to an embodiment of the present invention, a solution for providing location-based services can be summarized in two ways. First, as shown in FIG. 8, in collecting a digital signage audio data from an external server and constructing a database, the audio data is reclassified based on location information of each digital signage mapped to the audio data. That is, as shown in FIG. 8, the first DB 810 is constructed by collecting audio data of the digital signage located in “Gwangjin-gu”, and the audio data of the digital signage located in “Gangnam-gu” is collected and made. Build a 2DB (820). Therefore, upon receiving the request signal for the audio data ID list from the mobile device, the mobile device receives current location information of the mobile device together, accesses only the local area DB, and then configures and transmits only the user's preferred list.

On the other hand, although not shown in FIG. 8, as another embodiment, all the audio data lists held in the database of the server are transmitted to the mobile device. It is assumed that the list also includes the location information of the digital signage. The mobile device automatically generates only the audio data ID list of the digital signage included within a predetermined distance (eg, within 1 km) from the location of the current mobile device using the GPS sensor. In this design, there is no need to separately build a DB for each region and group on the server.

Both embodiments described above are within the scope of the present invention, the communication environment. A person skilled in the art may select only one solution or combine two solutions according to a database.

9A is a diagram illustrating a case where a mobile device is located in a plurality of digital signage environments according to an embodiment of the present invention. Hereinafter, referring to FIG. 9A, a case in which a mobile device according to an embodiment of the present invention is located in a plurality of digital signage environments will be described.

First, as illustrated in FIG. 9A, a user having a mobile device 900 according to an embodiment of the present invention is placed in an arbitrary environment in which four digital signs 931, 932, 933, and 934 are located. Consider the case. Of course, the above-described digital signs may be located at the visible distance of the user or at an invisible distance, or the present invention may be applied even when some digital sign screens are hidden. On the other hand, according to the prior art, the user can only check the video screen output from the digital signage, a solution that can select only the audio or the audio data of their preference in a plurality of digital signage environment easily developed It wasn't.

On the other hand, according to an embodiment of the present invention, the number of the digital signage desired by the mobile device 900 (for example, Ch210, Ch533, Ch112, Ch888, shown in Figure 9a) It is possible to listen to the audio data of the desired digital signage in a manner. Although not shown in FIG. 9A, a method of displaying a QR code or the like instead of the channel number may be used.

In addition, as described in the foregoing drawings, the present invention may provide a location-based audio service in order to improve user convenience and accuracy, which will be described below in more detail with reference to FIG. 10.

9B is a diagram illustrating a display screen of a digital signage according to an embodiment of the present invention. FIG. 9B is an enlarged view of the digital sign 931 shown in FIG. 9A.

In the digital signage 931 according to an embodiment of the present invention, two graphic options are additionally designed without outputting only a general video screen as illustrated in FIG. 9B. First, a unique channel number 940 assigned to each digital sign is output, and a guide message 950 indicating that audio service is available is displayed together. Accordingly, the user who has downloaded the application based on the location-based audio service according to an embodiment of the present invention simply inputs the channel number 940 to the mobile device, thereby providing audio data together with the video of the corresponding digital signage 931. It can be easily confirmed.

FIG. 10 is a diagram illustrating a first graphic screen in which a mobile device provides a location based audio service according to an embodiment of the present invention. Hereinafter, referring to FIG. 10, a first graphic screen for providing a location-based audio service by a mobile device according to an embodiment of the present invention will be described. On the other hand, it will be assumed that the environment shown in Figure 9a is applied.

Through communication with an external server, the mobile device receives and displays a list of available audio services, as shown in FIG. 10. At this time, not only the channel information but also the user's selection guide, a guide message (xx daily report outdoor advertisement, rr community center, gg subway station, hhh city hall) for outputting the digital signage of each channel (audio data) is also output.

Therefore, the user using the mobile device of FIG. 10 can effect the primary confirmation by the channel number and the secondary confirmation by the identification information of the digital signage. Meanwhile, it is assumed that the list shown in FIG. 10 is sorted in no particular order.

FIG. 11 illustrates a second graphic screen in which a mobile device provides a location-based audio service according to an embodiment of the present invention. Unlike FIG. 10, FIG. 11 illustrates a case in which IDs on the list are changed in a certain order.

First, as shown in Figure 9a, the user with a mobile device xx ilbo is 100m apart, rr community center is 150m apart, hhh city hall is 50m apart, gg subway station is 420m apart I will assume.

At this time, it is likely that the closest hhh viewing is most likely from the user's point of view, which is most likely to be close to the current digital signage.

Therefore, as shown in FIG. 11, unlike FIG. 10, the audio data ID 1100 of the viewing hhh is positioned at the top of the list. The rest of the digital signs also adjusted their positions in order of distance from the nearest to the farthest based on the distance value (e.g. 1st ID (hhh watch, 50m), 2nd ID (xx daily report, 100m) 3rd ID (rr Community Center, 150m), 4th ID (gg Metro Station, 420m).

Meanwhile, in FIG. 10 and FIG. 11, there is no graphic suggesting position and direction on the list, which may cause some difficulty to the user. The solution to this will be described later in detail with reference to FIG.

FIG. 12 illustrates a third graphic screen in which a mobile device provides a location based audio service according to an embodiment of the present invention. Hereinafter, the situation of FIG. 9A is assumed and will be described with reference to FIG. 12.

The mobile device that executes the location-based audio service displays a list of digital signs that provide audio data in a separate channel, as shown in FIG. 12.

At this time, unlike the previous drawings it is designed to display the positional relationship between the mobile device and each digital signage in more detail. First, as shown in FIG. 12, first information 1200 indicating the direction of the digital signage and second information 1210 indicating the distance are displayed together on the basis of the mobile device.

Therefore, unlike the prior art, the user can easily select not only the digital signage directly in front of the audio data of the remotely located digital signage. Furthermore, there is a technical effect of inducing a user to move toward the corresponding digital signage by displaying a specific direction together.

FIG. 13 illustrates a fourth graphic screen in which a mobile device provides a location-based audio service according to an embodiment of the present invention.

First, the list shown in (a) of FIG. 13 is the same as in FIG. However, a user possessing a mobile device according to an embodiment of the present invention may move in a specific direction. For example, in FIG. 9A, a linear movement of the digital signage 931 of the channel 210 is located in the direction of xx ilbo.

At this time, as shown in (b) of FIG. 13, detailed items such as the order and direction / distance of the list are automatically changed.

That is, in FIG. 13A, the digital signage of channel 888 and the mobile device were closest to each other (50m). However, due to the movement of a user (mobile device), as shown in FIG. Since digital signage is closest to the mobile device, channel 210 is at the top of the list.

14 is a diagram illustrating a case where a mobile device is located in a plurality of digital signage environments having different altitude values according to an embodiment of the present invention. In the previous drawings, it is assumed that a location service is provided based on latitude / longitude among location information. On the other hand, in FIG. 14, a solution in which the altitude values of the plurality of digital signs are different will be proposed.

As shown in FIG. 14, building A is spaced 5 m on each floor, and consists of three floors in total.

In addition, one digital signage 1400, 1410, 1420 is located in each floor. In this case, there are limitations in that a plurality of digital signs cannot be distinguished only by latitude and longitude values. For example, although the user stays in front of the digital signage on the second floor, according to the above-described embodiments, the digital signage 1400 on the second floor and the digital signs 1410 and 1420 on the other floor are identified to provide a service. I can't.

As a solution to this problem, it will be described with reference to FIG. 15.

FIG. 15 illustrates a fifth graphic screen in which a mobile device provides a location-based audio service according to an embodiment of the present invention. Assuming FIG. 14, FIG. 15 will be described.

First, as shown in FIG. 15, a mobile device according to an embodiment of the present invention provides a list of location based audio services. According to the exemplary embodiments of the previous drawings, there is a digital sign of channel 321 at about 3m in the left direction, the same as the digital signage of channel 400 at about 3m in the left direction, and the channel at about 3m in the left direction. Guides you through 75 digital signs.

However, in the embodiment shown in Fig. 15, an indicator displaying the altitude value is additionally designed. That is, by indicating that the digital signage of channel 400 is an altitude value 1421 of + 5m, the user can predict that a separate digital signage exists in a higher layer than the current floor in which the user stays.

In addition, by indicating that the digital signage of channel 75 is an altitude value 1411 of -5m, the user can predict that a separate digital signage exists in a lower layer than the current floor in which the user is staying.

Finally, the digital signage of channel 321 indicates that the 0m altitude difference 1401 indicates that the user can simultaneously use the video and audio of the digital signage on the current floor without moving additional floors.

As described above, according to an embodiment of the present invention, there is a technical effect of providing only the audio data ID list optimized according to the movement of the mobile device by inserting location information into the audio data.

Furthermore, according to another embodiment of the present invention, the above-described audio data is mapped for each digital signage, and there is a feature in defining separate channel information for identifying the same.

Furthermore, although the drawings are shown for convenience of explanation, it is also possible to design a new embodiment to be implemented by merging the embodiments described in each drawing. It is also within the scope of the present invention to design a computer-readable recording medium in which a program for executing the previously described embodiments is recorded according to the needs of those skilled in the art.
