As shown in FIG. 5, the local advertisement content is an advertisement of businesses having a business place in a specific area, and includes a location of the business place. For example, these workplaces are convenience stores, restaurants, beauty salons, hospitals, health clubs, bank branches, and academies. A business place is not limited to a place where a product is sold or a service is provided, and includes any place related to a location to be communicated to a customer.

Local advertising content is data made of multimedia data such as image, video, and voice.

Location information of the local advertising content is information indicating the location of the business place. The location information is displayed on a map or a map, a moving distance, and a moving direction, and included in the local advertisement content.

Meanwhile, the advertisement content storage unit 31 stores information about a desired advertisement time, an advertisement time, a business location, and an advertisement target region together with the local advertisement content. The desired advertisement time and advertisement time mean the exposure time or exposure time of the advertisement desired by the advertiser.

In addition, the advertisement target area is data regarding in which region the advertisement is to be advertised. The target area for advertisement is data about a region classified by administrative districts or a specific region where advertisements are desired to be displayed among themselves.

The advertisement target area may be directly expressed as a specific area, or may be expressed as a specific location including a business location within a predetermined radius or a business location.

Display 32 displays the local advertising content.

The display 32 is a general display device such as an LCD or LED display, and is a device capable of displaying advertisement content on a screen. It is desirable that the display is sized enough to be able to see the contents displayed on the screen and to be carried by people even within a distance of 1m or more and less than 10m. That is, the screen of the display is preferably 10 inches to 100 inches. However, it is not necessarily limited to this size.

The positioning unit 33 grasps the moving position and the screen direction of the display. The positioning unit 33 is equipped with a GPS device, etc. to receive a GPS signal and to grasp the current moving position therefrom. In addition, the current position may be determined using the signal strength of the base station.

In addition, the positioning unit 33 is equipped with a device that can measure the orientation, such as an electronic compass to grasp the orientation of the screen direction of the display.

The controller 35 displays the corresponding local advertisement content on the display according to the moving position, and displays the location information of the local advertisement content to change according to the screen direction. In particular, the controller 35 displays the location information of the local advertisement content at a time opposite to the screen direction.

As shown in FIG. 6A, when the publisher 11 holds the display device 30, the screen direction of the display 32 is direction A. FIG. At this time, since the viewer 13 looks at the display 32 from the opposite side, the viewing direction of the viewer 13 is the direction B opposite to the screen direction.

That is, the controller 35 displays the location information on the display at the opposite point in the screen direction, that is, from the viewpoint of the advertisement viewer 13.

As the method of displaying the location information by the controller 35, there may be a method of displaying a map or a map, or a method of displaying only the moving distance and the moving direction.

First, when the location information of the local advertisement content is displayed as a map or a map, the controller 35 determines the direction of the up direction of the map or the map as the direction opposite to the screen direction. In addition, the controller 35 displays the movement position on the map or the map.

As another exemplary embodiment, when the location information of the local advertisement content indicates a moving distance and a moving direction of an advertisement target business site, the controller 35 sets the moving position and the reference position of the moving direction as the moving position and the moving direction. The reference direction of is set as the direction opposite to the screen direction and displayed. In addition, the controller 35 displays the movement distance and the movement direction in a direction display graphic or language.

For example, in the region as shown in FIG. 7A, the publisher 11 is located at the S point, and the business place of the displayed advertisement content is located at the D point. In the drawing of Fig. 7A, the upper side is in the north direction. In this case, as shown in FIG. 7B, an example in which the display screen direction of the display device 30 held by the publisher 11 is south (first direction) and east (second direction) will be described. do.

8 is a method of displaying the location information included in the advertising content on a map or a map. FIG. 8A illustrates contents displayed on the screen of the display in the first direction, and FIG. 8B illustrates position information displayed in the second direction. That is, since the opposite direction of the screen direction is west, FIG. 8B shows a map so that the west of FIG. 7A faces upward.

 9 illustrates a method of displaying location information of advertisement content in a moving distance and a moving direction of an advertisement target business site. FIG. 9A illustrates contents displayed on the screen of the display in the first direction, and FIG. 9B illustrates position information displayed in the second direction. That is, FIG. 9B shows "right" because the destination is on the right side when viewed in the opposite direction of the screen direction. At this time, the distance is displayed by calculating the distance from the S point to the D point.

On the other hand, the controller 35 selects the local advertisement content by reflecting any one or more of the reference radius, the block, the presence or absence of the lane and the width of the moving position.

As described above, the local advertisement content is stored in the storage unit 31 together with information about the business location and the advertisement target region. The controller 35 determines the movement position of the display device 30 and displays local advertisement content corresponding to the movement position. At this time, the local advertisement content including the moving location is selected and displayed.

Accordingly, as shown in FIG. 10, when the location of the business place is located within a certain radius (reference radius) of the moving position or in a certain block including the moving position, the advertisement content of the corresponding place is selected. In this case, the block may be determined differently according to the presence or width of the lane. For example, if a wide lane is next to you, it is desirable to avoid displaying local advertising content wherever there is a business across the lane.

Alternatively, the controller 35 displays local advertisement content corresponding to the moving position and the screen direction. For example, the controller 35 displays local advertisement content related to a position opposite to the screen direction in the moving position. That is, the advertisement content of the target business place behind the screen direction (advertiser viewing position) is not selected.

In addition, the controller 35 may expand the range if there is no advertising target business place within the range, such as the reference radius. Meanwhile, the controller 35 adjusts the time and time of the advertisement in consideration of the exposure time or exposure time of the advertisement content. For example, in the case of a business that is open only in the evening, if the advertising content is displayed only in the evening and the advertisement is to be advertised within 30 minutes, the advertisement exposure time is limited to 30 minutes or less.

When there are a plurality of advertisement contents to be exposed in a moving position, the priority is determined using factors such as exposure time and advertisement cost as a variable to select one advertisement contents.

The advertisement receiver 36 receives and stores local advertisement contents from the advertisement server 40 through a wireless network, and receives the local advertisement contents according to the moving position in real time.

When the publisher 11 moves to a specific position, the advertisement content corresponding to the moving position is received, stored, and displayed in real time. Through this, the advertisement display device 30 can be moved to any location in the country, there is an effect that does not need to store all the local advertising content of all the business sites in the country.

In addition, when the advertisement content is received and displayed in real time, the advertiser 12 may change the advertisement content content in real time. For example, if you do not plan to have a 50% shiny sale for an hour from the current time, there is an advantage that the sale advertisement can be displayed immediately. In particular, if the item is to be sold only on the day, if there is a lot of inventory will be able to advertise the sale at a high discount.

The advertisement exposure recorder 37 records the exposure information of the local advertisement content and transmits it to the advertisement server 40. In particular, the advertisement exposure recording unit 37 photographs the screen direction of the display with a camera installed on the front of the display, and measures and records the number of advertisement exposures from the photographed image.

The exposure information of the advertisement content includes basic information such as the display (output) time of the advertisement content, the display position, and the like, and analysis information on how many people are actually exposed to the advertisement content. If the camera is installed on the front of the display 32 and the screen orientation is taken, people in front of the screen can be photographed when the advertisement is exposed. Therefore, there is a method of analyzing how many people were by analyzing the photographed image, or a method of tracking the eyes of a person and counting the number of people who gaze at the display.

The advertisement display apparatus 30 described above mainly targets advertisements of the advertiser 11 having a business place in the region, but is not limited thereto. The advertisement display apparatus 30 may be used for displaying his or her opinion or for information guidance.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the said Example, this invention is not limited to the said Example and can be variously changed in the range which does not deviate from the summary.

The present invention is applicable to the development of a mobile advertisement display device that can be worn or carried by an individual and selects and displays a local advertisement content on a display according to a position where the individual moves. In particular, the present invention is useful for developing a mobile advertisement display device that displays the location of the target business place together with the local advertisement content on the advertisement display, and displays the location information of the business place from the perspective of the advertisement viewer.
