  In step S (hereinafter referred to as “S”) 10 in FIG. 4, the control unit 10 (radio wave receiver 11) of the portable information terminal 1 determines whether or not a beacon radio wave has been received. When the portable information terminal 1 is within the beacon radio wave reception range (the distance from the beacon terminal 8 is within 10 m, for example), the control unit 10 (radio wave reception unit 11) receives the beacon radio wave. Can do. When the beacon radio wave is received (S10: YES), the control unit 10 moves the process to S11. On the other hand, when the beacon radio wave is not received (S10: NO), the control unit 10 stays in this process and waits for the reception of the beacon radio wave.

In S <b> 11, the control unit 10 (detection information transmission unit 12) of the portable information terminal 1 transmits radio wave detection information to the information providing server 4. The radio wave detection information includes the beacon ID included in the beacon radio wave received in S10, the radio wave intensity of the beacon radio wave, and the terminal ID of the portable information terminal 1.
In S <b> 20, the control unit 40 (detection information receiving unit 41) of the information providing server 4 receives the radio wave detection information transmitted from the portable information terminal 1.
In S <b> 21, the control unit 40 (terminal position specifying unit 42) refers to the beacon management table 51 and specifies the beacon terminal 8 that is the transmission source of the beacon radio wave based on the beacon ID included in the radio wave detection information.

Here, the beacon management table 51 will be described with reference to FIG.

And the control part 40 can pinpoint the approximate position of the portable information terminal 1 by the distance between the portable information terminal 1 and one or a plurality of beacon terminals 8.
For example, consider a case where the radio wave detection information received from the portable information terminal 1 of the user in the store S shown in FIG. 2 includes the beacon IDs of the beacon terminals 8A and 8B and the respective radio wave information. When the radio field intensity from the beacon terminal 8A is larger than the radio field intensity from the beacon terminal 8B, the user of the portable information terminal 1 is in the “PC section” of the store S, and its position is close to the “camera section”. , It can be specified that it is within a range away from the “printer section”.

If data of the same terminal ID is accumulated (S24: YES), the control unit 40 moves the process to S25. On the other hand, when the data of the same terminal ID is not accumulated (S24: NO), the control unit 40 moves the process to S27.

In S25, the control unit 40 compares the data with the same terminal ID temporarily stored in the storage unit 50 to determine whether or not the data stored in S23 has changed. When the portable information terminal 1 remains in the range of the same position, there is no change between the latest data. However, when the user carrying the portable information terminal 1 is moving, there is a change between the latest data. If there is a change in the data (S25: YES), the control unit 40 moves the process to S26. On the other hand, when there is no change in the data (S25: NO), the control unit 40 moves the process to S27.
In S <b> 26, the control unit 40 (movement direction determination unit 43) determines the movement direction of the portable information terminal 1 from the temporal change of the accumulated data. And the control part 40 produces the moving direction data showing the determined moving direction.
For example, the user's portable information terminal 1 in the store S shown in FIG. 2 has received radio waves from the beacon terminal 8A and the beacon terminal 8B in the past. Consider the case of receiving radio waves. In this case, the control unit 40 can determine that the portable information terminal 1 is moving in the “printer sales area” direction (Y1 direction) of the store S. In addition, the mobile information terminal 1 moves in any direction (X1 direction or X2 direction) of the store S due to a change in radio field intensity from the beacon terminal 8A and the beacon terminal 8B received by the mobile information terminal 1 in the past. Can be determined.

The product information includes detailed contents and coupon contents.
Returning to FIG. 6, in S <b> 31, the control unit 40 determines the ratio of extracting the product information corresponding to the position in each area based on the specified position of the portable information terminal 1. Thereby, the ratio of the merchandise information of the merchandise displayed near the position of the portable information terminal 1 can be increased, and a lot of merchandise information can be provided near the position of the portable information terminal 1.
In S32, the control unit 40 extracts the detailed content of the product information from the product information table 52 at the determined ratio.

In S33, the control unit 40 determines whether there is movement direction data. The case where there is movement direction data is a case where movement direction data is created in S26 of FIG. If there is moving direction data (S33: YES), the control unit 40 moves the process to S34. On the other hand, when there is no moving direction data (S33: NO), the control unit 40 moves the process to S35.
In S <b> 34, the control unit 40 extracts and creates data related to the moving direction from the beacon management table 51 based on the moving direction data. The data related to the moving direction is, for example, “I am heading to the printer section”, and the control unit 40 extracts the area name in the direction in which the portable information terminal 1 is heading from the beacon management table 51. . Thereafter, the control unit 40 moves the process to S36.

In this case, since the portable information terminal 1 remains at the position (# 1), the control unit 10 of the portable information terminal 1 displays the provision screen 30 shown in FIG.

The providing screen 30 illustrated in FIG. 8A includes current position information 30a, product detailed information 30b, 30c, and 30d, and a coupon display button 30e.
An area name is displayed in the current position information 30a. The area name corresponds to the position range specified in S22 of FIG. 4, and in this example is “PC section”.
The product detailed information 30b, 30c, 30d displays the area name corresponding to the product information extracted in S32 of FIG. 6 and the detailed content of the product information. In the case of this example, since the portable information terminal 1 is located in the PC section, the product detail information 30b is displayed higher than the product detail information 30c and 30d, and the amount of information is large. Further, since the portable information terminal 1 is closer to the printer department, the product detail information 30c is displayed at a higher level than the product detail information 30d.
The coupon display button 30e is a button for displaying the coupon information created in S35 of FIG. When the user of the portable information terminal 1 selects the coupon display button 30e, the coupon screen 31 shown in FIG. 8B is displayed on the touch panel display 26 of the portable information terminal 1. The fact that the user of the portable information terminal 1 is not moving means that he / she is interested in the product displayed at that position and may purchase it. Therefore, the information providing system 100 can promote purchase for the user by providing the user with a coupon corresponding to the product at that position.

Next, the case where the portable information terminal 1 moves from (# 1) to (# 2) in FIG.
The portable information terminal 1 is still closest to the beacon terminal 8A, but is in a position close to the beacon terminals 8B and 8C.

The provision screen 32 illustrated in FIG. 8C includes current position information 32a, product detail information 32b, 32c, and 32d, and movement direction information 32f.
An area name is displayed in the current position information 32a. The area name corresponds to the position specified in S22 of FIG. 4, and in this example is “PC section”.
The product detailed information 32b, 32c, 32d displays the area name corresponding to the product information extracted in S32 of FIG. 6 and the detailed content of the product information. In the case of this example, since the portable information terminal 1 is located in the PC section, the product detail information 32b is still displayed higher than the product detail information 32c and 32d, and the amount of information is large. However, the information amount of the product detail information 32b is lower than that of the provision screen 30 in FIG. Instead, the information amount of the product detail information 32c of the printer department where the portable information terminal 1 is approaching is increasing.
The movement direction information 32f displays the movement direction data created in S26 of FIG.
Thus, when the portable information terminal 1 is moving, the user of the portable information terminal 1 can be guided to various sales floors in the store S by also indicating the information of the movement destination.

As described above, the information providing system 100 according to the first embodiment has the following effects.
(1) By receiving radio waves from the beacon terminals 8A to 8C arranged at a plurality of positions in the store S, the mobile information terminal 1 transmits radio wave detection information, and the information providing server 4 is connected to the mobile information terminal 1. The area is specified, and information related to the specified area is transmitted to the portable information terminal 1. Therefore, the user can obtain information corresponding to the position of the portable information terminal 1.
Further, the information providing server 4 specifies an approximate position based on the area of the portable information terminal 1, extracts the product information at that position, and transmits it to the portable information terminal 1. Therefore, the user can obtain product information corresponding to the position of the portable information terminal 1.
Furthermore, since the user can obtain coupon information corresponding to the position of the portable information terminal 1, the user can be promoted to purchase products.

(2) The information providing server 4 extracts a lot of product information corresponding to the position of the beacon terminal 8 located near the portable information terminal 1 among the plurality of beacon terminals 8. Therefore, the user can obtain a lot of information corresponding to the position of the portable information terminal 1.
(3) The information providing server 4 displays the provision screen data so that the product information corresponding to the position of the beacon terminal 8 located near the portable information terminal 1 among the plurality of beacon terminals 8 is prominently displayed. It is generated and transmitted to the portable information terminal 1. Therefore, the information corresponding to the position of the portable information terminal 1 can be easily shown to the user.

(4) The information providing server 4 can determine the moving direction of the portable information terminal 1 by repeatedly specifying the position of the portable information terminal 1. And the information regarding a moving direction can be provided to a user. Therefore, it is possible to prompt the user to move in the moving direction.
(5) The information providing server 4 can provide the area name in the moving direction to the user in addition to the area name related to the current position of the portable information terminal by extracting the area name corresponding to the position in the moving direction. Therefore, it is a motivation to turn the user in the moving direction.

<Beacon terminal 8>
The beacon terminal 8 (8D, 8E) is a terminal provided in the store 200S as shown in FIG. The beacon terminal 8D and the beacon terminal 8E transmit different radio waves, and the beacon terminal 8D has a wider range in which the beacon radio wave can be received. The radio wave transmitted by the radio wave transmission unit 87 of the beacon terminal 8D corresponds to, for example, Bluetooth Class 1, and the beacon radio wave is, for example, as long as the portable information terminal 1 exists within a radius of 50 m centered on the beacon terminal 8D. It can be received by the portable information terminal 1. On the other hand, the radio wave transmitted by the radio wave transmitter 87 of the beacon terminal 8E corresponds to, for example, Bluetooth Class 2, and the beacon radio wave is present within the radius of 10 m centered on the beacon terminal 8E, for example. Then, it can be received by the portable information terminal 1.

The beacon terminal 8D is provided in a wide area. Specifically, beacon terminal 8D is provided in the central part of area D, which is a home appliance department.
On the other hand, the beacon terminal 8E is used for specifying the sales floor in more detail in the home appliance sales floor. The beacon terminal 8E is arranged such that its radio wave transmission range is inside the radio wave transmission range of the beacon terminal 8D. Then, the radio wave intensity (for example, −30 dBm) of the beacon radio wave of the beacon terminal 8D at the installation position of the beacon terminal 8E is set as the threshold value of the beacon terminal 8D. Further, the beacon radio wave reception range of the beacon terminal 8E is area E, the right side of which is, for example, a cooking home appliance area, and the left side is, for example, a washing machine area.

<Information providing server 204>
The information providing server 204 includes a control unit 40, a storage unit 250, and a communication I / F unit 59.
The storage unit 250 stores a beacon management table 251, a product information table 252, and a radio wave table 253.
The beacon management table 251 is a table for managing the beacon terminals 8 (8D, 8E).
As shown in FIG. 11A, the beacon management table 251 stores a beacon ID, a class, installation area information, and an area name in association with each other. The class corresponds to a radio wave transmitted from the beacon terminal 8 and relates to a Bluetooth class.
The product information table 252 is a table related to product information, as shown in FIG.
The radio wave table 253 is a table related to beacon radio waves. As shown in FIG. 10B, the radio wave table 253 stores the radio wave intensity x, the distance y from the beacon terminal 8, and the level in association with each other. The distance y from the beacon terminal 8 varies depending on the class of the beacon terminal 8.

<Specific example>
Next, a specific example of the above process will be described.
FIG. 12 is a diagram for explaining a specific example of the information providing system 200 according to the second embodiment.
FIG. 13 is a diagram illustrating a display example on the portable information terminal 1 according to the second embodiment.
The processing by the information providing system 200 is the same as that in the first embodiment.
FIG. 12A shows the transition of the position of the portable information terminal 1 in the store 200S, and shows that the portable information terminal 1 is moving from (# 1) to (# 2).
First, when the portable information terminal 1 is at the position (# 1), the portable information terminal 1 receives the radio wave from the beacon terminal 8D, the radio wave from the beacon terminal 8E, as shown in FIG. Is being received. Therefore, the control unit 40 can specify that the portable information terminal 1 is in the area E. And since the electromagnetic wave from beacon terminal 8D is smaller than a threshold value (in this example, -30 dBm), it can specify that the position in an area is R among area E. Further, although the data of the terminal ID of the portable information terminal 1 is temporarily stored in the temporary storage area of the storage unit 250, it is assumed that there is no change from the latest one. In this case, since the portable information terminal 1 remains at the position (# 1), the control unit 10 of the portable information terminal 1 displays the provision screen 230 shown in FIG.
On the providing screen 230 shown in FIG. 13A, the cooking appliance sales floor that is the current position and the product list are displayed. The offer screen 230 also displays a coupon display button for displaying a coupon.

Next, a case where the portable information terminal 1 moves from (# 1) to (# 2) in FIG.
The portable information terminal 1 is still receiving the radio wave from the beacon terminal 8D and the radio wave from the beacon terminal 8E. And since the electromagnetic wave from beacon terminal 8D is smaller than a threshold value (-30dBm), it can specify that the position in an area is R among the areas E. In addition, since the radio wave intensity of the beacon radio wave of the beacon terminal 8D and the radio wave intensity of the beacon radio wave of the beacon terminal 8E are both increased, the control unit 40 is in the center direction of the beacon terminal 8E and in the X2 direction ( It can be determined that the user is heading (see FIG. 10A). Therefore, the control unit 10 of the portable information terminal 1 displays the provision screen 232 illustrated in FIG. 13B on the touch panel display 26.
The provision screen 232 shown in FIG. 13B displays the product list of the cooking appliance sales floor at the current position at the top. Since the portable information terminal 1 is moving toward the washing machine sales floor in the X1 direction, a part of the product list of the washing machine sales floor is displayed on the provision screen 232.

Thus, according to the information providing system 200 of the second embodiment, there are the following effects.
The information providing server 204 can identify the range of the position of the portable information terminal 1 even when the intensity of the beacon radio waves emitted from the beacon terminals 8D and 8E are different. Therefore, the information providing system 200 can provide the user of the portable information terminal 1 with the product information at that position.
