[0009] Hereinafter, the embodiments will be described with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. Furthermore, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0010] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0011] (Embodiment) [composition] First, a configuration of an advertisement display system according to an embodiment will be described. Fig. 1 is a block diagram showing a functional configuration of an advertisement display system 10 according to an embodiment. Fig. 2 is a diagram showing a space to which the advertisement display system 10 according to an embodiment is applied.

[0012] The advertisement display system 10 is a system that can measure the position of a user in a space 81 (more specifically, an indoor space) within a commercial facility 80 and display advertising content targeted to the user. As shown in FIG. 1 , the advertisement display system 10 includes a plurality of lighting fixtures 20, an information terminal 40, a positioning server 50, an advertisement display server 60, and an advertisement display device 70. The advertisement display system 10 may include a plurality of advertisement display devices 70. The advertisement display system 10 may also be applied to facilities other than the commercial facility 80.

[0013] First, lighting fixture 20 will be described. Lighting fixture 20 is a lighting fixture that illuminates space 81 in commercial facility 80. Lighting fixture 20 is, for example, a ceiling light, a downlight, or a spotlight. Lighting fixture 20 also has a function of periodically transmitting a beacon signal including an ID of lighting fixture 20. Lighting fixture 20 is an example of a second communication device.

[0014] Note that a dedicated beacon transmitter (another example of the second communication device) that transmits a beacon signal may be installed in space 81, and it is not essential that lighting fixture 20 transmits a beacon signal. Alternatively, a communication device (another example of the second communication device) that communicates via WiFi may be installed in space 81. The communication device that communicates via WiFi is, for example, a WiFi router, and is mounted on lighting fixture 20. Alternatively, the communication device that communicates via WiFi may be installed near lighting fixture 20 and communicate with information terminal 40.

[0015] Next, the information terminal 40 will be described. The information terminal 40 is a mobile terminal carried by a user located in the space 81. Specifically, the information terminal 40 is a mobile terminal such as a smartphone, a tablet terminal, or a PDA (Personal Digital Assistant). The information terminal 40 is an example of a first communication device.

[0016] Next, the positioning server 50 will be described. The positioning server 50 receives information (signal strength information) indicating the communication state of wireless communication between the information terminal 40 and each of the plurality of lighting fixtures 20 from the information terminal 40, and measures the position of the information terminal 40 in the space 81 based on the received signal strength information. The positioning server 50 is, for example, a cloud computer provided outside a building (facility) that constitutes the space 81, but may also be an edge computer provided within the building.

[0017] Next, a description will be given of the advertisement display server 60. The advertisement display server 60 processes information related to the display of advertisement content. The advertisement display server 60 includes a communication unit 61, an information processing unit 62, and a storage unit 63.

[0018] The communication unit 61 is a communication circuit for the advertisement display server 60 to communicate with each of the information terminal 40, the positioning server 50, and the advertisement display device 70. The communication unit 61 may perform wireless communication or wired communication.

[0019] The information processing unit 62 performs information processing related to the display of advertisement content. The information processing unit 62 is realized, for example, by a microcomputer, but may also be realized by a processor or a dedicated circuit. The information processing unit 62 includes, as functional components, an acquisition unit 64, a control unit 65, and an identification unit 66. The functions of the information processing unit 62 are realized by hardware such as a microcomputer or a processor constituting the information processing unit 62 executing a computer program (software) stored in the storage unit 63.

[0020] The storage unit 63 is a storage device that stores information necessary for the above information processing. The information stored in the storage unit 63 includes a computer program executed by the information processing unit 62. The storage unit 63 is realized by, for example, a semiconductor memory.

[0021] In this embodiment, the advertisement display server 60 and the positioning server 50 are described as separate servers, but they may be the same server.

[0022] Next, the advertisement display device 70 will be described. The advertisement display device 70 displays advertisement content based on an advertisement display command from an advertisement display server. The advertisement display device 70 is, for example, a projection device that projects advertisement content onto the floor or wall of the space 81, but may also be a digital signage device that displays advertisement content on a display panel.

[0023] Here, a plurality of advertisement contents (substantial advertisement contents) are stored in advance in the advertisement display device 70 together with IDs. According to such a configuration, the advertisement display server 60 can cause the advertisement display device 70 to display the advertisement contents by transmitting an advertisement display command including the IDs of the advertisement contents to the advertisement display device 70. Note that the advertisement display command may include substantial advertisement contents, and in this case, substantial advertisement contents do not need to be stored in the advertisement display device 70.

[0024] [Initial Settings] In order to receive advertisements displayed in a space 81 within a commercial facility 80, the user installs a predetermined application program in the information terminal 40. At this time, the user performs a predetermined operation to register the user's attribute information in the information terminal 40. Here, the attribute information includes the user's name, address, sex, age, occupation, and the like. FIG. 3 is a table showing an example of the attribute information.

[0025] The attribute information is transmitted from the information terminal 40 to the advertisement display server 60, and is stored (registered) as user information in association with the ID of the application program. Fig. 3 is a diagram showing an example of user information.

[0026] The above application program may be a dedicated application program for allowing a user to receive advertisements displayed in space 81 within commercial facility 80, but in this embodiment, it is realized as an application program used for shopping in commercial facility 80. In other words, this application program includes not only functions related to the use of commercial facility 80, but also functions related to measuring the position of information terminal 40.

[0027] The function related to the use of the commercial facility 80 is, for example, a shopping function at the commercial facility 80. The shopping function includes a function such as payment for products or management of points awarded when purchasing products.

[0028] In this way, if the application program has a shopping function, it is possible to link product purchase history information to user information, which makes it possible to use the purchase history information in addition to or instead of the attribute information when determining the ID of advertising content, which will be described later.

[0029] [Display behavior of advertising content] As described above, the advertisement display system 10 can display advertisement content to the user. The display operation of such advertisement content will be described below. Fig. 4 is a sequence diagram of the display operation of advertisement content performed by the advertisement display system 10.

[0030] The user performs a predetermined input for executing the application program on the information terminal 40, and the information terminal 40 accepts the predetermined input (S11). The information terminal 40 receives a beacon signal from each of the plurality of lighting devices 20 (S12), and measures the received signal strength indicator (RSSI) of the received beacon signal (S13).

[0031] Each of the lighting devices 20 periodically transmits a beacon signal, and the beacon signal includes an ID of the lighting device 20. The ID is, for example, a Media Access Control (MAC) address, but may be another ID.

[0032] Next, the information terminal 40 transmits signal strength information, in which the measured received signal strength is associated with the ID of the lighting device 20 that transmitted the beacon signal, contained in the beacon signal, to the positioning server 50 (S14). The signal strength information is information that indicates the received signal strength of each of the multiple beacon signals together with the ID of the lighting device 20 that transmitted the beacon signal. The signal strength information includes the ID of the application program.

[0033] Positioning server 50 receives the signal strength information. Positioning server 50 stores arrangement information indicating the installation positions (coordinates) of multiple lighting fixtures 20 in space 81. FIG. 5 is a diagram showing an example of the arrangement information, in which the IDs of lighting fixtures 20 are associated with the installation positions (coordinates). The arrangement information may also include attribute information of the area to which the installation positions belong, in addition to the IDs and installation positions (coordinates) of lighting fixtures 20. Note that, although the coordinates are two-dimensional in the example of FIG. 5, they may be three-dimensional.

[0034] The positioning server 50 measures the position of the information terminal 40 based on the received signal strength information and the arrangement information shown in FIG. 4 (S15). Specifically, the positioning server 50 identifies the position of the lighting device 20 that is the source of the beacon signal in the space 81 based on the ID of the lighting device 20 that is the source of the beacon signal included in the signal strength information and the arrangement information. That is, the positioning server 50 may perform three-point positioning using the beacon signal. The received signal strength of the beacon signal can be regarded as the distance from the lighting device 20 that is the source of the beacon signal to the information terminal 40. Therefore, the positioning server 50 can measure (estimate) the position of the information terminal 40 based on the position of the lighting device 20 that is the source of the beacon signal and the distance from the lighting device 20 to the information terminal 40. For example, the positioning server 50 measures the position of the information terminal 40 with an accuracy of about 3 m to 5 m by three-point positioning.

[0035] Specifically, the position of the information terminal 40 is the coordinates of the information terminal 40 in the space 81. Note that any existing algorithm may be used as a method for measuring the position based on the signal strength information and the arrangement information.

[0036] The positioning server 50 may also measure the position of the information terminal 40 by a PDR (Pedestrian Dead Reckoning) method using detection data of an acceleration sensor included in the information terminal 40. For example, the positioning server 50 measures the position of the information terminal 40 with an accuracy of about 1.5 m.

[0037] Next, the positioning server 50 transmits an advertisement display request to the advertisement display server 60 (S16). The advertisement display request includes the ID of the application program included in the signal strength information and the location information indicating the location of the information terminal 40 measured in step S15.

[0038] The communication unit 61 of the advertisement display server 60 receives the advertisement display request. For example, the identification unit 66 identifies attribute information of the user of the information terminal 40 by collating the ID of the application program included in the advertisement display request with the user information stored in the storage unit 63, and determines the ID of the advertisement content to be displayed to the user based on the identified attribute information (S17). The ID of the advertisement content is determined by a predetermined algorithm based on the attribute information. For example, candidates for the ID of the advertisement content are determined based on the attribute information, and the ID is randomly determined from among these candidates. Note that the owner of the commercial facility 80 or the like can freely set what advertisement content is to be displayed to a user with what attribute information. The user information stored in the storage unit 63 includes user information such as the user's preferences inferred from purchasing behavior by the control unit 65, in addition to information registered when the application program is installed. For example, the control unit 65 determines that the user has "stayed" when the user has been in a specific area for a certain period of time by shopping or window shopping at a certain store. Furthermore, the control unit 65 may categorize the attributes of the areas where the user has "stayed," and reflect the attributes of the highest category in the user information in the storage unit 63 as user attribute information.

[0039] The upper category extracted by the control unit 65 can be freely set, for example, to the top 10%. The certain time used by the identification unit 66 to determine the presence or absence of a "stay" can be freely set so as to distinguish between passing through a specific area and stopping by. For example, the certain time may be defined as the shortest distance through a specific area divided by walking speed, and the walking speed is, for example, the walking speed of an average person.

[0040] The updating of the user information performed by the control unit 65 and the storage unit 63 may be manual or automatic, and may be automated by, for example, AI. In addition, the extraction of this additional user information may be performed by the positioning server 50.

[0041] FIG. 6 is a flowchart showing the operation of the positioning server 50.

[0042] Specifically, positioning server 50 receives the ID of information terminal 40 and the ID of the lighting fixture 20 that has communicated with information terminal 40 (step S20). Here, the ID of the lighting fixture 20 that has communicated with information terminal 40 may be the ID of the lighting fixture 20 associated with second communication device 44 that has communicated with information terminal 40.

[0043] Next, the positioning server 50 converts the received IDs of the lighting devices 20 into area information (step S21). For example, the positioning server 50 converts the received IDs of the lighting devices 20 into area information that indicates spatial attributes within the space 81, such as “in front of the EV” or “resting space.”

[0044] Next, the positioning server 50 transmits the time when the user stayed in the area, the ID of the information terminal 40 (that is, the user ID), and the area information to the advertisement display server 60 (step S22).

[0045] The advertisement display server 60 may calculate the user's stay time in the area from the information indicating the user's stay time in the area. For example, the advertisement display server 60 may determine the user's stay time in the area as the difference between the latest stay time and the earliest stay time among a plurality of stay times in the area.

[0046] Furthermore, the acquisition unit 64 acquires the location information included in the advertisement display request, and when the control unit 65 determines based on the acquired location information that the information terminal 40 has reached a predetermined place in the space 81, it transmits an advertisement display command to the advertisement display device 70 installed in the vicinity of the predetermined place (S18). The advertisement display command is specifically transmitted to the advertisement display device 70 by the communication unit 61. The advertisement display command includes the ID of the advertisement content determined in step S17.

[0047] When the advertisement display device 70 receives the advertisement display command, it displays the advertisement content (S19). Specifically, the advertisement display device 70 identifies advertisement content associated with the ID included in the advertisement display command from among a plurality of advertisement contents stored in the advertisement display device 70, and projects the identified advertisement content onto the floor, wall, or the like of the space 81. At this time, the advertisement display device 70 may automatically correct the advertisement content and project the identified advertisement content onto the floor, wall, or the like of the space 81. Here, the automatic correction is tilt correction or the like. For example, the advertisement projection device 70 may hold a list of advertisements, and store the advertisement content ID, the advertisement content attribute (for example, indicating the content of the content), and the advertisement content image processing method, such as the projection angle of the image of the projected advertisement content, in association with each other.

[0048] The timing from receiving the advertisement display command to displaying the advertisement content is not particularly limited. For example, if the above-mentioned predetermined location and the projection position of the advertisement content of the advertisement display device 70 (the installation position of the advertisement display device 70) are close (for example, within 1 m), the advertisement display device 70 displays the advertisement content immediately after receiving the advertisement display command. Also, if the above-mentioned predetermined location and the projection position of the advertisement content of the advertisement display device 70 (the installation position of the advertisement display device 70) are far away and it takes time for the user to reach the projection position of the advertisement content, the advertisement display device 70 displays the advertisement content after a certain period of time has elapsed since receiving the advertisement display command. For example, this is the case when the predetermined location is the entrance to an up escalator and the projection position is near the middle of the up escalator.

[0049] The time from when the advertisement display command is received until the advertisement content is displayed is, for example, determined in advance as a rule, but the advertisement display command may include timing instruction information for instructing the timing of displaying the advertisement content.

[0050] As described above, the advertisement display system 10 includes an acquisition unit 64 that acquires location information indicating the location of an information terminal 40 carried by a user located in a space 81 in a commercial facility 80, measured based on the state of wireless communication between the information terminal 40 and a lighting fixture 20 installed in the space 81, a control unit 65 that causes an advertisement display device 70 installed in the space 81 to display advertisement content based on the acquired location information, and an identification unit 66 that identifies attribute information of the user. The advertisement content is selected based on the identified attribute information. The advertisement display device 70 is a projection device that projects the advertisement content.

[0051] For example, when advertising content is displayed on the display unit of the information terminal 40, the user may not notice the advertising content. In response to this, the advertising display system 10 displays the advertising content on the advertising display device 70 installed in the space 81, thereby enhancing the advertising effect of the advertising content.

[0052] Furthermore, the advertisement display device 70 stores a plurality of advertisement contents including the advertisement content in advance, and the control unit 65 transmits the ID of the advertisement content to the advertisement display device 70, thereby causing the advertisement display device 70 to display the advertisement content.

[0053] As a result, the advertisement display system 10 can issue a command to display advertisement content by transmitting the ID of the advertisement content having a small amount of information, thereby making it possible to reduce the amount of communication and suppress occurrence of delays due to communication.

[0054] [Behavior when multiple people are detected] FIG. 7 is a flowchart showing the operation of the advertisement display system 10 when a plurality of people are detected.

[0055] The acquisition unit 64 receives the ID of the information terminal 40, the duration of stay in a specific area, and attribute information of the area from the positioning server 50 (step S30).

[0056] The identification unit 66 detects whether or not a user has entered a specific area at five-second intervals (step S31). That is, the control unit 65 determines whether or not a user has stayed in a specific area for a certain period of time at five-second intervals. Note that this determination is not limited to five-second intervals, and may be made at regular intervals such as several seconds, or may be made randomly within a predetermined period of time.

[0057] Next, the identification unit 66 determines whether or not the IDs of multiple users have been detected (step S32). That is, the identification unit 66 determines whether or not the IDs of multiple information terminals 40 have been detected. Detecting the IDs of multiple information terminals 40 may mean detecting the IDs of two or more information terminals during a predetermined time period.

[0058] When the identification unit 66 determines that the IDs of multiple users have been detected (Yes in step S32), the identification unit 66 outputs the ID of the first user detected (step S33). The identification unit 66 identifies the ID of the first information terminal 40 detected among the IDs of the multiple information terminals 40 acquired by the acquisition unit 64. The identification unit 66 may output the ID of the identified information terminal 40.

[0059] Alternatively, the identification unit 66 may identify the ID of the information terminal 40 determined to have the highest priority according to a predetermined algorithm. For example, the identification unit 66 may determine that the ID of the information terminal 40 having the longest cumulative stay time is the highest priority among the IDs of the information terminals 40 detected simultaneously.

[0060] The identification unit 66 may refer to a list of user IDs (or IDs of the information terminal 40) stored in the storage unit 63 and select one user ID (or ID of the information terminal 40). The list of user IDs (or IDs of the information terminal 40) may store the user ID (or ID of the information terminal 40) in association with membership information such as the user's gender, and user attribute information estimated from the location information of the user (or the information terminal 40). The user attribute information estimated from the location information of the user (or the information terminal 40) may be information indicating what type of store the user visited.

[0061] Next, the identification unit 66 identifies attribute information of the user corresponding to the identified user ID (step S34). For example, the identification unit 66 identifies attribute information such as the age or gender of the user linked to the ID of the information terminal 40. The identification unit 66 may also identify attribute information of the user identified from the position information of the information terminal 40 and attribute information of the area (for example, attribute information of "having children" identified because the user stayed in the "children's goods" area).

[0062] Next, the specification unit 66 determines an ID (advertising ID) of the advertising content according to the specified attribute information (step S35). The specification unit 66 selects and determines the ID of the advertising content linked to the attribute information of the user specified in step S34.

[0063] The identification unit 66 may determine the ID of the advertisement content by referring to a list of the IDs of the advertisement content stored in the storage unit 63. The ID of the advertisement content may be stored in the list of the IDs of the advertisement content in association with the type of advertisement (such as the content of the advertisement content). Furthermore, the list of the advertisement IDs may store tag information in association with the ID of the advertisement content. For example, the tag information may be information such as the gender of the user or the type of store visited.

[0064] If the identification unit 66 determines that the IDs of multiple users have not been detected (No in step S32), the identification unit 66 selects and determines the advertisement display device 70 that will display the advertisement content from the list of IDs of the advertisement display devices 70 (step S36).

[0065] For example, the identification unit 66 may select the advertisement display device 70 closest to the user's position identified from the position information of the information terminal 40, and determine it as the advertisement display device 70 that will display the advertisement content. Alternatively, the identification unit 66 may select the advertisement display device 70 that is a predetermined distance away in a predetermined direction from the user's position identified from the position information of the information terminal 40, which is derived by a predetermined algorithm, and determine it as the advertisement display device 70 that will display the advertisement content.

[0066] The identification unit 66 may select the advertisement display device 70 by referring to the list of advertisement display devices 70 stored in the storage unit 63. For example, the list of advertisement display devices 70 may store attribute information of the area in which the advertisement projection equipment 70 is installed and the ID of the advertisement projection equipment 70 in association with each other.

[0067] Next, the identification unit 66 indicates the ID of the determined advertisement content to the selected advertisement display device 70 (step S37). After step S35 or step S36, the identification unit 66 transmits the ID of the advertisement content determined by the identification unit 66 to the advertisement display device 70 as the ID of the advertisement content to be displayed by the advertisement display device 70.

[0068] [Modification of positioning server] Note that the specific embodiment of the positioning server 50 is not particularly limited. For example, the positioning server 50 may have a plurality of beacon receivers distributed in the space 81, and the positioning server 50 may measure the position of the information terminal 40 based on the received signal strength of each of the plurality of beacon receivers of the beacon signal transmitted by the information terminal 40. In other words, the positioning server 50 may measure the position of the information terminal 40 based on a configuration in which the relationship between the transmission and reception of the beacon signal is reversed from that described above.

[0069] Furthermore, the positioning server 50 may measure the current position of the information terminal 40 using the receiving angle (AoA: Angle of Arrival) of the beacon signal in addition to the received signal strength. The positioning server 50 may measure the position of the information terminal 40 by combining the above-mentioned positioning method using the beacon signal with a positioning method called PDR (Pedestrian Dead Reckoning) using an acceleration sensor or the like provided in the information terminal 40. The positioning server 50 may measure the position of the information terminal 40 based on UWB (Ultra Wide Band) communication.

[0070] [Variation when advertising content is not displayed for a certain period of time] In the above embodiment, the control unit 65 acquires a location ID and an application ID from the information terminal 40, and determines the advertisement content and the advertisement display device 70 based on the location ID and the application ID, but the control unit 65 of the advertisement display system 10 may display the advertisement content even when there is no input from the information terminal 40 to the advertisement display system 10. For example, the control unit 65 of the advertisement display system 10 may cause the advertisement display device 70 that has not displayed content for a certain period of time to display advertisement content with an ID randomly determined by the identification unit 66.

[0071] [Modification of the method for determining advertising content] Furthermore, the identification unit 66 may determine the ID of the advertisement content according to the current time, or may determine the ID of the advertisement content according to the location where the advertisement display device 70 is installed. For example, the identification unit 66 determines the ID of the advertisement content to be projected by the advertisement display device 70 according to the floor of the commercial facility where the advertisement display device 70 is installed.

[0072] In the above embodiment, only the ID of the advertisement content determined by the specification unit 66 is transmitted from the communication unit 61 of the advertisement display server 60 to the communication unit (not shown) of the advertisement display device 70, but the advertisement content itself may be transmitted instead of the advertisement content ID. In this case, the advertisement content corresponding to the advertisement content ID is stored in the storage unit 63.

[0073] In the above embodiment, the advertisement display system 10 has been described as displaying advertisements in real time, but may be used for other purposes. As described above, the advertisement display system 10 may be used to appropriately display news, disaster prevention information, and the like, tailored to the user.

[0074] [Effects, etc.] As described above, the advertising display system 10 includes an acquisition unit 64 that acquires location information indicating the location of a first communication device carried by a person located in a space 81 within a facility and a second communication device installed in the space 81, and a control unit 65 that causes an advertising display device 70 installed in the space to display advertising content based on the acquired location information.

[0075] Such an advertisement display system 10 can present advertisements and the like to users in real time based on the position of the communication device in the space 81.

[0076] Moreover, for example, the advertisement display device 70 is a projection device that projects advertisement content.

[0077] Such an advertisement display system 10 can project advertisements or the like onto the floor, wall, or the like in the space 81 in real time.

[0078] Also, for example, a plurality of advertisement contents including the advertisement content are stored in advance in the advertisement display device 70, and the control unit 65 causes the advertisement display device 70 to display the advertisement content by transmitting the ID of the advertisement content to the advertisement display device 70.

[0079] Such an advertisement display system 10 can project appropriate advertisements and the like from the advertisement display device 70 in real time while suppressing delays due to communication.

[0080] For example, the system further includes a specification unit 66 that specifies attribute information of a person, and the advertisement content is selected based on the specified attribute information.

[0081] Such an advertisement display system 10 can present to a user appropriate advertisement content that matches the characteristics of the user.

[0082] Also, for example, the advertisement content is randomly selected from among a plurality of advertisement contents determined based on the specified attribute information.

[0083] Such an advertisement display system 10 can present a wide variety of more appropriate advertisement contents to the user in the space 81.

[0084] Also, for example, advertising content is selected based on the current time.

[0085] Such an advertisement display system 10 can present more timely advertisement content, etc. to users in the space 81.

[0086] Also, for example, the advertisement content is selected based on the floor on which the advertisement display device 70 is installed.
