  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the content providing system according to the embodiment of the present invention includes a user terminal 1 and a server device 4 that provides the user terminal 1 with content corresponding to the position of the user terminal 1. The user terminal 1 is a mobile terminal owned by a user such as a smartphone or a tablet terminal, and measures the position (longitude, latitude, and altitude) of the terminal itself.

  The user terminal 1 receives a navigation signal from the GPS satellite 2 and performs positioning. The user terminal 1 also shows error correction information (time and orbit of each GPS satellite 2 and ionospheric delay in the positioning area) from the quasi-zenith satellite 3 (satellite “Michibiki” etc. in the QZSS (quasi-zenith satellite system)). Correction information including error information etc.) is received and positioning is performed with high accuracy.

  The user terminal 1 is equipped with an atmospheric pressure sensor, and the altitude is calculated with high accuracy in consideration of the atmospheric pressure value measured by the atmospheric pressure sensor.

  The user terminal 1 periodically measures the position and notifies the server device 4 of the position of the own terminal.

  The server device 4 provides content according to the position of the user terminal 1. Here, the server device 4 provides the user terminal 1 with different contents according to the horizontal position (latitude / longitude) and the vertical position (altitude) of the user terminal 1. The content to be provided is, for example, a coupon, a limited (commemorative) image or video, an advertisement, or the like.

  For example, as shown in FIG. 2, when there is a user on the first floor of a high-rise building (hereinafter referred to as “tower T”), the server device 1 waits for the user terminal 1 for a short day ticket for the heavenly tour. Providing advertisements notifying you that you can purchase in time and that you can take a commemorative photo at a discount price on the Tembo Deck.

  When there is a user on a restaurant floor 20 meters above the tower T, the server device 1 provides the user terminal 1 with a discount coupon that can be used at a restaurant on the restaurant floor.

  When there is a user on the observatory deck 350 meters above the tower T, the server device 1 provides the user terminal 1 with a discount coupon for commemorative photography at the commemorative photography booth. Users can use a commemorative photo service at a discounted price.

  When there is a user in the observatory corridor 450 meters above the tower T, the server device 1 provides the user terminal 1 with a free coupon for commemorative photography at the commemorative photography booth. Users can use the commemorative photo service for free.

  Thus, according to this embodiment, even when the horizontal position (latitude / longitude) is the same, different contents can be provided to the user terminal 1 according to the vertical position (altitude).

  The user terminal 1 can measure the position (latitude / longitude) in the horizontal direction with high accuracy by signals from the GPS satellite 2 and the quasi-zenith satellite 3. For example, each of the user terminals 1 in a restaurant floor where a plurality of restaurants are adjacent and densely arranged. It may be difficult to identify individual restaurants. When different contents are prepared for each store, it is necessary to accurately identify which store the user carrying the user terminal 1 is (in front of which store) and provide the corresponding content.

  Therefore, in this embodiment, when it is not possible to specify which store is in front by only signals from the GPS satellite 2 or the quasi-zenith satellite 3, and the content to be provided cannot be selected, the store is identified by another method.

  For example, as shown in FIG. 3A, a screen for instructing the user terminal 1 to photograph the appearance of a store signboard or the like is displayed. The user photographs a store signboard or the like with the built-in camera of the user terminal 1. The user terminal 1 transmits the taken store image to the server device 4. The server device 4 detects the store name and the feature quantity of the appearance from the store image, determines which store the user is in, and transmits the content corresponding to the store to the user terminal 1.

  Or the screen which instruct | indicates to approach the ultrasonic transmitter installed in the store on the user terminal 1 is displayed. As illustrated in FIG. 3B, the user terminal 1 collects ultrasonic waves transmitted from the ultrasonic transmitter U with a microphone, performs analysis (for example, frequency analysis), and acquires information. The ultrasonic transmitter U transmits an ultrasonic signal including information that can identify the store. The user terminal 1 transmits the acquired information to the server device 4. The server device 4 determines which store the user is in from the received information, and transmits content corresponding to the store to the user terminal 1.

  Thus, when a detailed position cannot be specified only by a signal from a satellite, a store image obtained by photographing a signboard or an ultrasonic signal from an ultrasonic transmitter installed in the store is used in combination. Select and provide content according to location.

  FIG. 4 is a schematic configuration diagram of the user terminal 1. The user terminal 1 is a smartphone or a tablet terminal including a control unit 10, an antenna 11, a touch panel 12, a camera 13, a storage unit 14, a communication unit 15, an atmospheric pressure sensor 16, a microphone 17, and the like.

  The control unit 10 is a central processing unit (CPU) that controls the entire user terminal 1. The control unit 10 implements various functions by reading and executing the application program stored in the storage unit 14.

  The storage unit 14 is a storage area for storing programs and data necessary for the control unit 10 to execute various processes, and a semiconductor memory or the like is used.

  The antenna 11 receives signals from the satellites 2 and 3. The touch panel 12 accepts input from the user or displays content acquired from the server device 4.

  As the camera 13, a CCD camera or a CMOS camera is used. The communication unit 15 communicates with the server device 4. The atmospheric pressure sensor 16 outputs an atmospheric pressure value corresponding to the altitude as an electric power value. The microphone 17 collects ambient sounds.

  The control unit 10 has functions of a positioning unit 102, a content acquisition unit 104, a shooting control unit 106, an analysis unit 108, and an output processing unit 110.

  The positioning unit 102 receives signals from the plurality of GPS satellites 2 via the antenna 11 and receives error information of the GPS positioning signals and information necessary for precise positioning from the plurality of quasi-zenith satellites 3. Measure the position (latitude, longitude and altitude). The positioning unit 102 may calculate and correct the altitude of the terminal itself based on the atmospheric pressure value measured by the atmospheric pressure sensor 16. The positioning process by the positioning unit 102 may be performed autonomously every predetermined time or may be performed in response to a request from an application.

  The content acquisition unit 104 notifies the server device 4 of the location information of the user terminal 1 and acquires content corresponding to the location. If the content cannot be selected only by position information based on the signal from the satellite (cannot be narrowed down), the server apparatus 1 instructs another position acquisition method (store identification method).

  Store identification methods include photographing a store such as a signboard and acquiring an ultrasonic signal from an ultrasonic transmitter installed in the store.

  When the store image is instructed from the server device 1, the shooting control unit 106 activates the camera 13 and displays a store shooting screen as shown in FIG. 3A on the touch panel 12. When a user photographs a store signboard or the like, a store image is transmitted to the server device 1 via the communication unit 15.

  When acquisition of an ultrasonic signal is instructed from the server device 1, the microphone 17 is turned on. As shown in FIG. 3B, when the user approaches the ultrasonic transmitter U, ultrasonic waves are collected via the microphone 17. The analysis unit 108 analyzes the ultrasonic signal and acquires information included in the ultrasonic signal.

  The content acquisition unit 104 acquires the content selected from the location information of the user terminal 1 and the information included in the store image or the ultrasonic signal from the server device 4.

  The output processing unit 110 outputs the content acquired by the content acquisition unit 104. For example, an image (still image or moving image) is displayed on the touch panel 12, or a sound is output from a speaker (not shown).

  FIG. 5 is a schematic configuration diagram of the server device 4 which is a content providing device. The server device 4 may be composed of a single computer or a plurality of computers. As illustrated in FIG. 5, the server device 4 includes a control unit 40, a storage unit 42, and a communication unit 44. The control unit 40 is a central processing unit (CPU) that controls the entire server device 4. The control unit 40 implements various functions by reading and executing an operating system (OS) and application programs stored in the storage unit 42.

  The storage unit 42 is a storage area for storing programs and data necessary for the control unit 40 to execute various processes, and a hard disk, a semiconductor memory, or the like is used. The storage unit 42 has a content DB (database) in which position information and content data are stored in association with each other. The position information associated with the content data indicates a certain range of positions in consideration of measurement errors.

  When a plurality of small stores are adjacent and individual contents are prepared for each store, additional information for identifying each store is further associated. The additional information is, for example, information extracted from the feature extracted from the store name or store image, or the ultrasound transmitted from the ultrasound transmitter installed in the store.

  The communication unit 44 communicates with the user terminal 1 via a network such as the Internet or a LAN.

  The control unit 40 has functions of a position information reception unit 401, a content selection unit 402, an identification method instruction unit 403, an image reception unit 404, an ultrasonic information reception unit 405, and a content transmission unit 406.

  The position information receiving unit 401 receives position information from the user terminal 1.

  The content selection unit 402 selects content corresponding to the position information received from the user terminal 1 from the content DB.

  When a plurality of small stores are adjacent to each other and individual contents are prepared for each store, the position information received from the user terminal 1 may not be able to narrow down the contents (stores) to one. In this case, the additional information described above is required. The identification method instruction unit 403 instructs the user terminal 1 for an identification method for acquiring additional information. The identification method is store image shooting or ultrasonic sound collection.

  The image receiving unit 404 receives a store image from the user terminal 1 and detects characters and feature quantities from the store image by image recognition processing. The feature amount is not particularly limited, such as an EOH feature amount, an HOG feature amount, an Edgelet feature amount, or a Joint Haar-like feature amount.

  The ultrasonic information receiving unit 405 receives information obtained by analyzing the ultrasonic signal from the user terminal 1.

  The content selection unit 402 selects content data corresponding to the position of the user terminal 1 using characters and features detected from the store image or information acquired from the ultrasonic signal.

  The content transmission unit 406 transmits the content data selected by the content selection unit 402 to the user terminal 1.

  Next, a content providing method according to the present embodiment will be described using the flowchart shown in FIG.

  The user terminal 1 periodically measures the position of its own terminal (step S1). The user terminal 1 notifies the server device 4 of the measured position information. The location information includes latitude, longitude, and altitude.

  When there is only one content corresponding to the position of the user terminal 1 (steps S2_Yes, S3_Yes), the server device 4 transmits content data to the user terminal 1 (step S4). The user terminal 1 displays and outputs the content acquired from the server device 4 (step S5).

  When there are a plurality of contents corresponding to the position of the user terminal 1 (steps S2_Yes, S3_No), the server device 4 instructs the user terminal 1 on an identification method for narrowing down the contents (step S6).

  When the identification method uses an image, the camera 13 of the user terminal 1 is activated, and the user takes a picture of a store signboard (step S7). The user terminal 1 transmits the taken store image to the server device 4. The server device 1 detects characters and feature quantities from the store image by image recognition (step S8), and selects content data (step S9).

  If the identification method uses ultrasonic waves, the microphone 17 of the user terminal 1 is activated and collects ultrasonic waves from the ultrasonic transmitter installed in the store (step S10). The user terminal 1 analyzes the collected ultrasonic signal to acquire information, and transmits the acquired information to the server device 4 (step S11). The server device 1 selects content data based on the received information (step S9).

  The server device 4 transmits the content data selected in step S9 to the user terminal 1 (step S4). The user terminal 1 displays and outputs the content acquired from the server device 4 (step S5).

  As described above, according to the present embodiment, it is possible to provide the user with content corresponding to the three-dimensional position of the user. Even if the longitude and latitude are the same, different contents can be provided to users at different heights.

  In the above-described embodiment, an example of providing a coupon according to height has been described. However, an electronic stamp of a stamp rally, a complete certificate, or the like may be given.

  In the above embodiment, the method for identifying the store is not limited to the shooting of the store or the analysis of the ultrasonic wave, but may use a beacon signal or the like. For example, the user terminal 1 is instructed from the server device 4 to receive a beacon signal as an identification method for narrowing down contents. When the user terminal 1 receives a beacon signal from a transmitter installed in the store, the user terminal 1 transmits identification information included in the signal to the server device 4. The server device 4 selects content data based on the received identification information.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
