(Processing 1 of Item Providing System 1)

FIG. 5 is a sequence view illustrating a flow of item providing processing in the item providing system 1 according to Embodiment 1 of the invention. With the use of FIG. 5, description will be given for item providing processing that is processing up to display of an image indicating an acquired item by the mobile terminal 300 in the item providing system 1.

(Step S1)

The item management unit 122 of the server 100 requests the image output unit 124 to output an item presentation image. Upon reception of the request, the image output unit 124 outputs the item presentation image to the display device 200 via the server communication unit 110.

(Step S2)

Upon acquisition of the item presentation image via the display device communication unit 210, the image acquisition unit 224 of the display device 200 outputs the item presentation image to the display control unit 225.

(Step S3)

The display control unit 225 acquires the item presentation image and outputs an image signal indicating the item presentation image to the display device display unit 240. Upon acquisition of the image signal output from the display control unit 225, the display device display unit 240 displays the item presentation image indicated by the image signal.

An example of the image displayed by the display device display unit 240 at step S3 is illustrated in FIG. 6. FIG. 6 illustrates an example of the item presentation image displayed by the display device 200 in Embodiment 1 of the invention.

As illustrated in FIG. 6, the display device display unit 240 displays an item presentation image indicating each of a coupon C1 to a coupon C6. As illustrated in FIG. 6, NFC antennas 250 are arranged in the display region of each of the coupons of the coupon C1 to the coupon C6. For example, the NFC antenna 250(0,0), the NFC antenna 250(1,0), the NFC antenna 250(0,1), and the NFC antenna 250(1,1) are arranged in the display region of the coupon C1.

(Step S4)

Subsequently, the NFC control unit 221 receives an acquisition operation that is an operation of acquiring a target item of one or more items indicated by the item presentation image displayed on the display device display unit 240. An example of a method of receiving the acquisition operation by the NFC control unit 221 will be described with the use of FIG. 7. FIG. 7 illustrates an example of an acquisition operation in the item providing system 1 according to Embodiment 1 of the invention, in which (a) illustrates a state where the mobile terminal 300 is in proximity to the coupon C5 (target item) and (b) illustrates a state where the mobile terminal 300 is displaced from the target item.

When the mobile terminal 300 is in proximity to the coupon C5 as illustrated in FIG. 7(a), any of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) that are arranged in the region where the coupon 5 is displayed performs NFC communication with the NFC-I/F unit 350 of the mobile terminal 300. When detecting that any (for example, the NFC antenna 250(2,2)) of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) performs NFC communication, the NFC control unit 221 determines that the mobile terminal 300 is in proximity to the coupon C5 displayed in the region in which the NFC antenna 250(2,2) is arranged.

Each of the NFC antennas 250 outputs, to the NFC control unit 221, a detection signal indicating that the NFC-I/F unit 350 is in proximity and a distance by which the NFC-I/F unit 350 is made proximate. For example, when the mobile terminal 300 is in proximity to the coupon C5 as illustrated in FIG. 7(a), the NFC control unit 221 acquires the detection signal from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3). In such a state, the NFC antenna 250(2,2) and the NFC antenna 250(3,2) respectively output a detection signal A and a detection signal B, and when a value of the detection signal A is greater than a value of the detection signal B, the NFC control unit 221 determines that the NFC-I/F unit 350 is in proximity to the NFC antenna 250(2,2) and the NFC antenna 250(3,2) and is in proximity to the NFC antenna 250(2,2) more than the NFC antenna 250(3,2).

When the mobile terminal 300 is displaced from the coupon C5 as illustrated in FIG. 7(b), communication intensity of the NFC communication between the NFC antenna 250(2,2) and the mobile terminal 300 is reduced. The NFC control unit 221 determines whether or not the communication intensity of the NFC communication of the NFC antenna 250(2,2) that has performed the NFC communication is smaller than a predetermined value and a value of the detection signal output from other NFC antennas 250 is reduced. In other words, whether or not the mobile terminal 300 is displaced from the display surface of the display device 200 is determined. When determining that the communication intensity of the NFC communication of the NFC antenna 250(2,2) is smaller than the predetermined value and the value of the detection signal output from other NFC antennas 250 is reduced, the NFC control unit 221 determines that the mobile terminal 300 is displaced. The NFC control unit 221 then receives an acquisition operation that is an operation of acquiring the coupon C5. Note that, the NFC control unit 221 may be configured to determine whether no detection signal is acquired from the NFC antenna 250 that has output the detection signal and no detection signal is acquired from other NFC antennas 250, instead of determining whether or not the value of the detection signal is reduced.

As another method, when the mobile terminal 300 is displaced from the coupon C5 as illustrated in FIG. 7(b) while the NFC control unit 221 acquires the detection signal from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) as illustrated in FIG. 7(a), the detection signal output from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) becomes weak. The NFC control unit 221 then determines whether or not the detection signal output from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) has a value smaller than a predetermined value. When the NFC control unit 221 determines that the detection signal output from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) has a value smaller than the predetermined value and no detection signal is acquired from other NFC antennas 250, the NFC control unit 221 determines that the mobile terminal 300 is displaced. Further, the NFC control unit 221 receives the acquisition operation that is an operation of acquiring the coupon C5. Note that, the NFC control unit 221 may not be configured to determine whether or not each of the detection signals output from the NFC antennas 250 has a value smaller than the predetermined value and may be configured to determine whether or not an average value of the detection signals output from the NFC antennas 250 is smaller than a predetermined value.

(Step S5)

The NFC control unit 221 notifies the information output unit 222 that the acquisition operation has been received. Upon reception of the notification, the information output unit 222 outputs, to the server 100 via the display device communication unit 210, acquisition operation receiving information indicating that the acquisition operation has been received.

(Step S6)

The information acquisition unit 121 of the server 100 acquires the acquisition operation receiving information via the server communication unit 110. The information acquisition unit 121 then outputs the acquisition operation receiving information to the item management unit 122.

(Step S7)

Upon acquisition of the acquisition operation receiving information, the item management unit 122 refers to the acquisition operation receiving information and requests the image output unit 124 to output an item acquisition complete image indicating that a target item has been acquired. For example, when the acquisition operation receiving information that has been acquired indicates that the acquisition operation of acquiring the coupon C5 has been received, the item management unit 122 requests the image output unit 124 to output an item acquisition complete image indicating that the coupon C5 has been acquired. Upon reception of the request, the image output unit 124 outputs, to the display device 200 via the server communication unit 110, the item acquisition complete image indicating that the coupon C5 has been acquired.

(Step S8)

The image acquisition unit 224 of the display device 200 acquires the item acquisition complete image via the display device communication unit 210. The image acquisition unit 224 outputs the item acquisition complete image to the display control unit 225 and the display control unit 225 outputs an image signal indicating the item acquisition complete image to the display device display unit 240.

(Step S9)

The display device display unit 240 displays the item acquisition complete image indicated by the image signal. For example, when the item acquisition complete image is an item presentation image that does not include the coupon C5, the display device display unit 240 displays, as the item acquisition complete image, an item presentation image that does not include the coupon C5 as illustrated in FIG. 7(b).

(Step S10)

When the processing at step S7 ends, the item management unit 122 of the server 100 refers to the acquisition operation receiving information that has been acquired and acquires a target item from the item storage unit 130. The item management unit 122 requests the item output unit 123 to output the acquired target item. Upon reception of the request, the item output unit 123 outputs the target item to the display device 200 via the server communication unit 110.

(Step S11)

The item acquisition unit 223 of the display device 200 acquires the target item via the display device communication unit 210. The item acquisition unit 223 then outputs the target item to the NFC control unit 221.

(Step S12)

The NFC control unit 221 outputs the target item to the mobile terminal 300 via the NFC antenna 250 that performs NFC communication with the mobile terminal 300.

(Step S13)

The item acquisition unit 324 of the mobile terminal 300 acquires the target item via the NFC-I/F unit 350.

(Step S14)

The item acquisition unit 324 outputs the target item to the display control unit 321 and the display control unit 321 outputs an image signal indicating the target item to the mobile terminal display unit 340. The mobile terminal display unit 340 displays an image indicated by the image signal. For example, when the mobile terminal 300 acquires the coupon C5, the mobile terminal display unit 340 displays an image indicating the coupon C5 as illustrated in FIG. 7(b).

Note that, the server 100 may execute step S7 and step S10 described above by switching processing order thereof, and the similar also applies to other embodiments.

The target item may be set to the NFC antenna 250. In this case, the processing at step S10 and step S11 described above is not executed, and the NFC control unit 221 outputs the target item indicated by the acquisition operation received at step S4 to the mobile terminal 300 via the NFC antenna 250 at step S12.

As described above, in the item providing system 1 according to the present embodiment, the server 100 outputs an item presentation image to the display device 200 and acquires acquisition operation information from the display device 200. Then, the server 100 outputs an item acquisition complete image and the display device 200 displays the item acquisition complete image. For example, the server 100 outputs, as the item acquisition complete image, an item presentation image that does not include an acquired item. Thus, in the item providing system 1, an image displayed by the display device 200 is changed from an image that has been presented to the user to an image in which the item acquired by the user is not included, so that it is possible in the item providing system 1 to intuitively notify the user that the item has been acquired.

(Processing 2 of Item Providing System 1)

FIG. 8 is a sequence view illustrating a flow of item selection processing in the item providing system 1 according to Embodiment 1 of the invention. The item selection processing that is processing in which the mobile terminal 300 selects a target item in the item providing system 1 will be described with the use of FIG. 8.

Processing at step S1 to step S3 in which the server 100 outputs an item presentation image to the display device 200 and the display device 200 displays the item presentation image is the same as the processing described above, so that the description thereof will be omitted.

(Step S21)

The NFC control unit 221 determines whether or not there is an NFC antenna 250 performing NFC communication with the mobile terminal 300. In other words, the NFC control unit 221 determines whether or not the mobile terminal 300 is detected.

When determining that “the mobile terminal 300 is not detected” at step S21 (step S21: NO), the NFC control unit 221 returns to the processing at step S21 to determine again whether or not the mobile terminal 300 is detected.

(Step S22)

On the other hand, when determining that “the mobile terminal 300 is detected” at step S21 (step S21: YES), the NFC control unit 221 determines whether or not a predetermined time (for example, one second) has lapsed without change of the NFC antenna 250 performing NFC communication with the mobile terminal 300. For example, when the mobile terminal 300 and the NFC antenna 250(2,2) perform NFC communication, the NFC control unit 221 determines whether or not a predetermined time has lapsed without interruption of the communication between the mobile terminal 300 and the NFC antenna 250(2,2).

As another method, the NFC control unit 221 determines whether or not a predetermined time (for example, one second) has lapsed without change of the NFC antenna 250 outputting a detection signal. For example, when each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) outputs a detection signal, the NFC control unit 221 determines whether or not a detection signal has not been acquired for the predetermined time from NFC antennas 250 other than the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3).

When determining that “the predetermined time has not lapsed” at step S22 (step S22: NO), the NFC control unit 221 returns to the processing at step S21 to determine again whether or not the mobile terminal 300 is detected.

(Step S23)

On the other hand, when determining that “the predetermined time has lapsed” at step S22 (step S22: YES), the NFC control unit 221 receives a selection operation that is an operation of selecting an item displayed in the region in which the NFC antenna 250 performing NFC communication with the mobile terminal 300 is arranged. Alternatively, the NFC control unit 221 receives a selection operation of selecting an item displayed in the region in which the NFC antenna 250 outputting a detection signal is arranged. Then, the NFC control unit 221 notifies the information output unit 222 that the selection operation has been received. Upon reception of the notification, the information output unit 222 outputs, to the server 100 via the display device communication unit 210, selected item information indicating that the selection operation has been received. An example of a method of receiving the selection operation by the NFC control unit 221 will be described with the use of FIG. 9. FIG. 9 illustrates an example of a selection operation in the item providing system 1 according to Embodiment 1 of the invention, in which (a) illustrates a state where the mobile terminal 300 is in proximity to the coupon C5, (b) illustrates a state where the coupon C5 is selected, and (c) illustrates a state where the coupon C1 is selected.

When the mobile terminal 300 is in proximity to the coupon C5 as illustrated in FIG. 9(a), the NFC control unit 221 detects that the NFC antenna 250(2,2) performs NFC communication with the mobile terminal 300. When the mobile terminal 300 and the NFC antenna 250(2,2) have performed communication for a predetermined time without interruption, the NFC control unit 221 receives the selection operation of selecting the coupon C5.

When the mobile terminal 300 is in proximity to the coupon C5 as illustrated in FIG. 9(a), the NFC control unit 221 acquires the detection signal output from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3). When the NFC control unit 221 has continuously acquired the detection signal from each of the NFC antenna 250(2,2), the NFC antenna 250(3,2), the NFC antenna 250(2,3), and the NFC antenna 250(3,3) for a predetermined time and has not acquired a detection signal from other NFC antennas 250, the NFC control unit 221 receives the selection operation of selecting the coupon C5.

(Step S24)

The information acquisition unit 121 of the server 100 acquires, via the server communication unit 110, the selected item information output from the display device 200. The information acquisition unit 121 outputs the selected item information that has been acquired to the item management unit 122.

(Step S25)

The item management unit 122 refers to the selected item information output from the information acquisition unit 121 and requests the image output unit 124 to output an item selection complete image indicating that an item indicated by the selected item information is selected. For example, when the selected item information that has been acquired indicates the selection operation of selecting the coupon C5, the item management unit 122 requests the image output unit 124 to output the items selection complete image indicating that the coupon C5 is selected. Upon reception of the request, the image output unit 124 outputs, to the display device 200 via the server communication unit 110, the item selection complete image indicating that the coupon C5 is selected.

(Step S26)

The image acquisition unit 224 of the display device 200 acquires the item selection complete image via the display device communication unit 210. The image acquisition unit 224 outputs the item selection complete image to the display control unit 225 and the display control unit 225 outputs an image signal indicating the item selection complete image to the display device display unit 240.

(Step S27)

The display device display unit 240 displays the item selection complete image indicated by the image signal. For example, when the item selection complete image is an item presentation image in which the coupon C5 is highlighted, an item presentation image in which the coupon C5 is highlighted by a highlight 400 as illustrated in FIG. 9(b) is displayed as the item selection complete image. For example, when a position of the mobile terminal 300 is changed and the item selection complete image is an item presentation image in which the coupon C1 is highlighted, an item presentation image in which the coupon C1 is highlighted as illustrated in FIG. 9(c) is displayed as the item selection complete image.

(Step S28)

When the processing at step S25 ends, the item management unit 122 of the server 100 refers to the selected item information that has been acquired and acquires, from the item storage unit 130, the selected item that is selected. The item management unit 122 outputs the selected item that has been acquired to the item output unit 123. The item output unit 123 outputs the selected item that has been acquired to the display device 200 via the server communication unit 110.

(Step S29)

The item acquisition unit 223 of the display device 200 acquires the selected item via the display device communication unit 210. The item acquisition unit 223 outputs the selected item to the NFC control unit 221.

(Step S30)

The NFC control unit 221 outputs the selected item to the mobile terminal 300 via the NFC antenna 250 performing NFC communication with the mobile terminal 300.

(Step S31)

The item acquisition unit 324 of the mobile terminal 300 acquires the selected item via the NFC-I/F unit 350.

(Step S32)

The item acquisition unit 324 outputs the selected item to the display control unit 321 and the display control unit 321 outputs an image signal indicating the selected item to the mobile terminal display unit 340. The mobile terminal display unit 340 displays an image indicated by the image signal. For example, when the mobile terminal 300 selects the coupon C5, the mobile terminal display unit 340 displays an image indicating that the coupon C5 is selected as illustrated in FIG. 9(b). For example, when the mobile terminal 300 selects the coupon C1, the mobile terminal display unit 340 displays an image indicating that the coupon C1 is selected as illustrated in FIG. 9(c).

Note that, the server 100 may execute step S25 and step S28 described above by switching processing order thereof, and the similar also applies to other embodiments.

As described above, in the item providing system 1 according to the present embodiment, the server 100 acquires selected item information and outputs an item selection complete image to the display device 200. The display device 200 then displays the item selection complete image. For example, an item presentation image in which a selected item is highlighted is displayed as the item selection complete image in the item providing system 1. Thus, it is possible in the item providing system 1 to intuitively notify the user which item is selected.

Note that, although an item presentation image in which a selected item is highlighted is used as an example of an item selection complete image, the item selection complete image is not limited thereto, and, for example, an item presentation image in which brightness of items other than the selected item is reduced or an item presentation image in which a size of the selected item is increased may be used as the item selection complete image. The item selection complete image is desired to be an image by which the user is able to be notified of a change in display of the selected item even in a state where the selected item is not seen by the user because the mobile terminal 300 is in proximity to the display device 200 and the mobile terminal 300 is positioned on the selected item.

(Processing 3 of Item Providing System 1)

FIG. 10 is a sequence view illustrating a flow of item acquisition cancellation processing in the item providing system 1 according to Embodiment 1 of the invention. The item acquisition cancellation processing that is processing in which the mobile terminal 300 cancels acquisition of an item in the item providing system 1 will be described with the use of FIG. 10.

First, processing at step S1 to step S14 in which the server 100 outputs an item presentation image and the mobile terminal 300 displays an image indicating an acquired item in the item providing processing is the same as the processing described above, so that the description thereof will be omitted.

(Step S41)

When the processing at step S14 ends, the item acquisition unit 324 of the mobile terminal 300 determines whether or not a predetermined time (for example, ten seconds or the like) has lapsed.

(Step S42)

When determining that “the predetermined time has lapsed” at step S41 (step S41: YES), the item acquisition unit 324 acquires the target item acquired at step S13. Then, the processing indicated in FIG. 10 ends.

(Step S43)

On the other hand, when determining that “the predetermined time has not lapsed” at step S41 (step S41: NO), the item acquisition unit 324 determines whether or not a cancellation operation is received from the user via the operation reception unit 360. The cancellation operation will be described with the use of FIG. 11. FIG. 11 illustrates an example of a cancellation operation in the item providing system 1 according to Embodiment 1 of the invention, in which (a) illustrates a state where an image indicating an item acquired by the mobile terminal 300 is displayed, (b) illustrates an operation of moving the mobile terminal 300 into proximity to the display device 200, and (c) illustrates the mobile terminal 300 and the display device 200 after the cancellation operation.

As illustrated in FIG. 11(a), a text 410 indicating that a coupon has been acquired and a cancel button 411 that receives an operation of canceling acquisition of the coupon are included in an image displayed on the mobile terminal display unit 340 by the mobile terminal 300 at step S14 described above. For example, when the operation signal acquisition unit 323 acquires an operation signal indicating that the cancel button 411 is pressed, the operation signal acquisition unit 323 outputs the acquired operation signal to the item acquisition unit 324. Upon acquisition of the operation signal, the item acquisition unit 324 determines that the cancellation operation is received.

As illustrated in FIG. 11(b), in a state where the coupon is displayed on the mobile terminal 300 and an item acquisition complete image is displayed on the display device display unit 240 of the display device 200, the mobile terminal 300 is made proximate to the region in which the acquired coupon has been displayed. Thereby, the item acquisition unit 324 is able to detect, via the NFC-I/F unit 350, that the mobile terminal 300 is in proximity to the display device 200. When detecting that the mobile terminal 300 is in proximity to the display device 200, the item acquisition unit 324 determines that the cancellation operation is received.

Note that, the display device 200 is desired to be configured not to receive, as the acquisition operation, an operation in which the mobile terminal 300 is displaced from the display device 200 next time after the cancellation operation is received. Such a configuration makes it possible to prevent the mobile terminal 300 from acquiring the canceled item again after the cancellation operation.

(Step S44)

When determining that “the cancellation operation is received” at step S43 (step S44: YES), the item acquisition unit 324 outputs, via the NFC-I/F unit 350, cancel information indicating that the acquisition of the item is canceled.

(Step S45)

The NFC control unit 221 of the display device 200 acquires the cancel information via the NFC antenna 250. The NFC control unit 221 outputs the cancel information to the information output unit 222.

Note that, when determining whether the cancel information is cancel information caused by pressing the cancel button 411 or cancel information caused by the mobile terminal 300 moving into proximity to the region in which the acquired coupon has been displayed, the NFC control unit 221 may perform the determination on the basis of a distance between the mobile terminal 300 and the display device 200. For example, the NFC control unit 221 may determine that cancel information acquired when communication intensity of NFC communication of the NFC antenna 250 is greater than a predetermined value (in other words, when the mobile terminal 300 and the display device 200 are closer to each other than a predetermined distance) is the cancel information caused by the mobile terminal 300 moving into proximity to the region in which the acquired coupon has been displayed. As another example, the NFC control unit 221 may determine that cancel information acquired when an average value of detection signals output from the respective NFC antennas 250 is greater than a predetermined value (in other words, when the mobile terminal 300 and the display device 200 are closer to each other than a predetermined distance) is the cancel information caused by the mobile terminal 300 moving into proximity to the region in which the acquired coupon has been displayed.

(Step S46)

The information output unit 222 outputs the cancel information to the server 100 via the display device communication unit 210.

(Step S47)

The information acquisition unit 121 of the server 100 acquires the cancel information via the server communication unit 110. The information acquisition unit 121 outputs the cancel information to the item management unit 122.

(Step S48)

Upon acquisition of the cancel information, the item management unit 122 requests the image output unit 124 to output an item presentation image. Upon reception of the request, the image output unit 124 outputs the item presentation image to the display device 200 via the server communication unit 110.

(Step S49)

(Step S50)

(Step S51)

After the processing at step S44 described above ends, the item acquisition unit 324 of the mobile terminal 300 requests the display control unit 321 to display an image indicating that the acquisition of the item is canceled. Upon reception of the request, the display control unit 321 outputs, to the mobile terminal display unit 340, an image signal that indicates the image indicating that the acquisition of the item is canceled. The mobile terminal display unit 340 displays the image indicated by the image signal. For example, an image that includes a text “canceled” 412 indicating that cancel is performed is displayed as illustrated in FIG. 11(c). Then, the processing indicated in FIG. 10 ends.

When determining that “the cancellation operation is not received” at step S43 described above (step S43: NO), the item acquisition unit 324 returns to the processing at step S41 to determine whether or not the predetermined time has lapsed.

As described above, in the item providing system 1 according to the present embodiment, the server 100 acquires cancel information and outputs an item presentation image to the display device 200. The display device 200 then displays the item presentation image. Thus, since an image to be presented to the user is changed from an item acquisition complete image to the item presentation image in the item providing system 1, it is possible to intuitively notify the user that the acquisition of the item is canceled.

Note that, when the mobile terminal 300 is configured to be able to output data via the mobile terminal communication unit 310 to at least one of the server 100 and the display device 200 as in configurations in Embodiment 2 and Embodiment 5 described later, the mobile terminal 300 may be configured to output cancel information to at least one of the server 100 and the display device 200.

When the mobile terminal 300 is configured to be able to output data to the server 100 via the mobile terminal communication unit 310 and, for example, the operation signal acquisition unit 323 of the mobile terminal 300 acquires an operation signal indicating that the cancel button 411 illustrated in FIG. 11(a) is pressed, the item acquisition unit 324 outputs cancel information to the server 100 via the mobile terminal communication unit 310 at step S44 described above. Then, the information acquisition unit 121 of the server 100 acquires the cancel information via the server communication unit 110 at step S47.

When the mobile terminal 300 is configured to be able to output data to the display device 200 via the mobile terminal communication unit 310 and, for example, the operation signal acquisition unit 323 of the mobile terminal 300 acquires an operation signal indicating that the cancel button 411 illustrated in FIG. 11(a) is pressed, the item acquisition unit 324 outputs cancel information to the display device 200 via the mobile terminal communication unit 310 at step S44 described above. Then, the information acquisition unit of the display device 200 acquires the cancel information via the display device communication unit 210 at step S45.

As described above, when the mobile terminal 300 is configured to be able to output data via the mobile terminal communication unit 310 to at least one of the server 100 and the display device 200, the mobile terminal 300 is able to execute item acquisition cancellation processing by outputting cancel information not via the NFC-I/F unit 350 but via the mobile terminal communication unit 310.

Embodiment 2

Another embodiment of the invention will be described as follows with reference to FIGS. 12 and 13. Note that, for convenience of description, the same reference signs are assigned to members having the same functions as those of members described in the aforementioned embodiment, and the description thereof will be omitted.

(Item Providing System 1a)

FIG. 12 schematically illustrates an item providing system 1a according to Embodiment 2 of the invention. The item providing system 1a includes a server 100a, a display device 200a, and a mobile terminal 300a as illustrated in FIG. 12. In the item providing system 1a, the mobile terminal 300a acquires, as a right to acquire a target item, item storage location information indicating a storage location at which the target item is stored. In the present embodiment, item storage location information indicating a storage location of an item displayed in a region in which each of the NFC antennas 250 is arranged is set to each of the NFC antennas 250 of the display device 200. Moreover, in the present embodiment, since an item is stored in the item storage unit 130, the storage location indicated by the item storage location information is an address of the item storage unit 130.

Note that, configurations of the server 100a, the display device 200a, and the mobile terminal 300a are respectively the same as the aforementioned configurations of the server 100, the display device 200, and the mobile terminal 300, so that the description thereof will be omitted.

(Processing of Item Providing System 1a)

FIG. 13 is a sequence view illustrating a flow of item acquisition right providing processing in the item providing system 1a according to Embodiment 2 of the invention. With the use of FIG. 13, the item acquisition right providing processing that is processing up to display of an image indicating a right to acquire an item acquired by the mobile terminal 300 in the item providing system 1a will be described.

First, processing at step S1 to step S4 in which the server 100a outputs an item presentation image and the display device 200a receives an acquisition operation is the same as the processing at step S1 to step S4 described above, so that the description thereof will be omitted.

(Step S61)

The NFC control unit 221 outputs, to the mobile terminal 300d via the NFC antenna 250 that has received the acquisition operation at step S4, item storage location information that is set to the NFC antenna 250. For example, when the NFC antenna 250(0,0) performs NFC communication with the mobile terminal 300a while the display device 200a displays the item presentation image illustrated in FIG. 6, the NFC control unit 221 outputs, to the mobile terminal 300a via the NFC antenna 250(0,0), item storage location information (item storage location information indicating a storage location of the coupon C1) that is set to the NFC antenna 250(0,0).

(Step S62)

The item acquisition unit 324 of the mobile terminal 300a acquires the item storage location information via the NFC-I/F unit 350.

Subsequently, processing at step S5 to step S9 in which the display device 200a outputs acquisition operation receiving information and displays an item acquisition complete image is the same as the processing at step S5 to step S9 described above, so that the description thereof will be omitted.

(Step S63)

When the processing at step S62 ends, the item acquisition unit 324 of the mobile terminal 300a requests a target item via the mobile terminal communication unit 310 to the server 100a that is a storage location indicated by the acquired item storage location information.

(Step S64)

The information acquisition unit 121 of the server 100a receives the request of the mobile terminal 300a via the server communication unit 110 and, in accordance with the request, requests the item management unit 122 to acquire the target item stored in the storage location.

(Step S65)

Upon reception of the request, the item management unit 122 acquires the target item stored in the storage location from the item storage unit 130. The item management unit 122 then outputs the acquired target item to the item output unit 123. The item output unit 123 outputs the acquired target item to the mobile terminal 300a via the server communication unit 110.

(Step S66)

The item acquisition unit 324 of the mobile terminal 300a acquires, via the mobile terminal communication unit 310, the target item output from the server 100a. Processing in which the mobile terminal display unit 340 displays an image indicating the target item is the same as that of step S14 described above, so that the description thereof will be omitted.

Note that, configurations of the server 100b, the display device 200b, and the mobile terminal 300b are respectively the same as the aforementioned configurations of the server 100, the display device 200, and the mobile terminal 300 described above, so that the description thereof will be omitted. Note that, it is configured so that the mobile terminal information includes at least a notification destination of the mobile terminal 300b in the present embodiment.

(Processing of Item Providing System 1b)

FIG. 15 is a sequence view illustrating a flow of item providing processing in the item providing system 1b according to Embodiment 3 of the invention. The item providing processing in the item providing system 1b will be described with the use of FIG. 15.

First, processing at step S1 to step S3 in which the server 100a outputs an item presentation image and the display device 200b displays the item presentation image is the same as the processing at step S1 to step S3 described above, so that the description thereof will be omitted.

(Step S71)

When the mobile terminal 300b is in proximity to the display device 200b and thereby performs NFC communication with the display device 200b, the NFC control unit 325 of the mobile terminal 300b requests the terminal information management unit 326 to output mobile terminal information. Upon reception of the request, the terminal information management unit 326 outputs the mobile terminal information via the NFC-I/F unit 350.

(Step S72)

The NFC control unit 221 of the display device 200 acquires the mobile terminal information via the NFC antenna 250. The NFC control unit 221 then outputs the mobile terminal information to the information output unit 222.

(Step S73)

Upon acquisition of the mobile terminal information, the information output unit 222 outputs the mobile terminal information to the server 100b via the display device communication unit 210.

(Step S74)

The information acquisition unit 121 of the server 100 acquires the mobile terminal information via the server communication unit 110. The information acquisition unit 121 then outputs the mobile terminal information to the item management unit 122.

(Step S75)

Upon acquisition of the mobile terminal information, the item management unit 122 requests the image output unit 124 to output an item presentation image associated with the mobile terminal information. Upon reception of the request, the image output unit 124 outputs the item presentation image associated with the mobile terminal information to the display device 200b via the server communication unit 110. For example, when an age of the user is included in the mobile terminal information, an item presentation image associated with the age of the user is output to the display device 200b.

(Step S76)

Upon acquisition of the item presentation image via the display device communication unit 210, the image acquisition unit 224 of the display device 200b outputs the item presentation image to the display control unit 225.

(Step S77)

Subsequently, processing at step S4 to step S9 in which the display device 200b receives an acquisition operation and the display device 200b displays an item acquisition complete image is the same as the processing described above, so that the description thereof will be omitted.

(Step S78)

When the processing of step S7 ends, the item management unit 122 of the server 100b refers to acquisition operation receiving information that has been acquired and acquires a target item from the item storage unit 130. Then, the item management unit 122 requests the item output unit 123 to output the acquired target item to a notification destination indicated by the acquired mobile terminal information. Upon reception of the request, the item output unit 123 outputs the acquired target item to the notification destination indicated by the mobile terminal information.

(Step S79)

The item acquisition unit 324 of the mobile terminal 300b acquires, via the mobile terminal communication unit 310, the target item output from the server 100b. Processing in which the mobile terminal display unit 340 displays an image indicating the target item is the same as that of step S14 described above, so that the description thereof will be omitted.

As described above, in the item providing system 1b according to the present embodiment, the server 100b acquires mobile terminal information of the mobile terminal that acquires an item and outputs an item presentation image associated with the mobile terminal information to the display device 200b. For example, when an age of the user is included in the mobile terminal information, an item presentation image according to the age of the user is able to be output, so that it is possible to present an item presentation image according to the user in the item providing system 1b. In a case where a notification destination is included in the mobile terminal information, the server 100b is able to output a target item to the mobile terminal 300b, and hence, even when the mobile terminal 300b and the display device 200b are away from each other, the target item is able to be output to the mobile terminal 300b in the item providing system 1b. Note that, in a case where the notification destination is not included in the mobile terminal information, the processing at step S10 to step S13 described above may be executed.

Embodiment 4

Another embodiment of the invention will be described as follows with reference to FIGS. 16 and 17. Note that, for convenience of description, the same reference signs are assigned to members having the same functions as those of members described in the aforementioned embodiments, and the description thereof will be omitted.

(Item Providing System 1c)

FIG. 16 schematically illustrates an item providing system 1c according to Embodiment 4 of the invention. The item providing system 1c includes a server 100c, a display device 200c, and a mobile terminal 300c as illustrated in FIG. 16. In the item providing system 1c, the mobile terminal 300c detects an acquisition operation and requests a target item.

(Processing of Item Providing System 1c)

FIG. 17 is a sequence view illustrating a flow of item providing processing in the item providing system 1c according to Embodiment 4 of the invention. The item providing processing in the item providing system 1c will be described with the use of FIG. 17.

(Step S81)

The NFC control unit 325 of the mobile terminal 300 detects an acquisition operation. The NFC control unit 325 then notifies the item acquisition unit 324 that the acquisition operation has been detected. A method of detecting the acquisition operation by the NFC control unit 325 will be described here. The NFC control unit 325 detects that NFC communication is performed and determines whether or not communication intensity of the NFC communication becomes smaller than a predetermined value. When determining that the communication intensity of the NFC communication becomes smaller than the predetermined value, the NFC control unit 325 detects the acquisition operation.

As another method, the NFC control unit 325 acquires a detection signal indicating that a plurality of NFC antennas 250 are in proximity and a distance from each of the plurality of NFC antennas 250. The NFC control unit 325 then determines whether or not a value of the detection signal becomes smaller than a predetermined value, and when determining that the value of the detection signal becomes smaller than the predetermined value, the NFC control unit 325 detects the operation as the acquisition operation.

For example, when the mobile terminal 300c is at the position of the mobile terminal 300 illustrated in FIG. 9(b), the NFC control unit 325 acquires a detection signal indicating that the NFC antenna 250(2,2), the NFC antenna 250(2,3), the NFC antenna 250(3,2), and the NFC antenna 250(3,3) are in proximity and a distance from each of the NFC antenna 250(2,2), the NFC antenna 250(2,3), the NFC antenna 250(3,2), and the NFC antenna 250(3,3). When the mobile terminal 300c is moved to the position of the mobile terminal 300 illustrated in FIG. 9(c), the NFC control unit 325 acquires a detection signal indicating a distance from each of the NFC antenna 250(0,0), the NFC antenna 250(0,1), the NFC antenna 250(1,0), and the NFC antenna 250(1,1). Thus, even when the mobile terminal 300c is moved from the position of the mobile terminal 300 illustrated in FIG. 9(b) to the position of the mobile terminal 300 illustrated in FIG. 9(c), the value of the detection signal acquired by the NFC control unit 325 is not reduced, so that the NFC control unit 325 does not detect the operation as the acquisition operation.

On the other hand, when the mobile terminal 300c is moved from the position of the mobile terminal 300 illustrated in FIG. 9(b) to the position of the mobile terminal 300 illustrated in FIG. 7(b), the value of the detection signal acquired by the NFC control unit 325 is reduced, so that the NFC control unit 325 detects the operation as the acquisition operation.

(Step S82)

Upon reception of the notification from the NFC control unit 325, the item acquisition unit 324 requests a target item to the display device 200c via the NFC-I/F unit 350.

(Step S83)

The NFC control unit 221 of the display device 200c receives, via the NFC antenna 250, the request from the mobile terminal 300c. Processing subsequent to step S5 in which the NFC control unit 221 receives the request and outputs acquisition operation receiving information is the same as the processing in the aforementioned embodiment, so that the description thereof will be omitted.

As described above, in the item providing system 1c according to the present embodiment, the mobile terminal 300c detects an acquisition operation and requests a target item to the display device 200c. Thus, since the display device 200c does not detect an acquisition operation in the item providing system 1c, it is possible to reduce processing of the display device 200c.

Embodiment 5

Another embodiment of the invention will be described as follows with reference to FIGS. 18 and 19. Note that, for convenience of description, the same reference signs are assigned to members having the same functions as those of members described in the aforementioned embodiments, and the description thereof will be omitted.

(Item Providing System 1d)

FIG. 18 schematically illustrates an item providing system 1d according to Embodiment 5 of the invention. The item providing system 1d includes a server 100d, a display device 200d, and a mobile terminal 300d as illustrated in FIG. 18. In the item providing system 1d, the mobile terminal 300d detects an acquisition operation and acquires storage location information.

(Processing of Item Providing System 1d)

FIG. 19 is a sequence view illustrating a flow of item providing processing in the item providing system 1d according to Embodiment 5 of the invention. The item providing processing in the item providing system 1d will be described with the use of FIG. 19.

First, processing at step S1 to step S3 in which the server 100d outputs an item presentation image and the display device 200d displays the item presentation image and processing at step S81 in which the mobile terminal 300d detects an acquisition operation are respectively the same as the processing at step S1 to step S3 and the processing at step S81 described above, so that the description thereof will be omitted.

(Step S91)

Upon reception of, from the NFC control unit 325, notification indicating that an acquisition operation has been detected, the item acquisition unit 324 of the mobile terminal 300d requests a target item to the display device 200c via the NFC-I/F unit 350.

(Step S92)

The NFC control unit 221 of the display device 200d receives the request via the NFC antenna 250.

(Step S93)

Subsequently, upon reception of the request, the NFC control unit 221 outputs, to the mobile terminal 300d, item storage location information that is set to the NFC antenna 250.

(Step S94)

The item acquisition unit 324 of the mobile terminal 300d acquires the item storage location information via the NFC-I/F unit 350. Processing subsequent to step S5 in which acquisition operation receiving information is output is the same as the processing in the aforementioned embodiment, so that the description thereof will be omitted.

As described above, in the item providing system 1d according to the present embodiment, the mobile terminal 300d detects an acquisition operation and requests item storage location information to the display device 200d. Thus, since the display device 200d does not detect an acquisition operation or does not acquire or output a target item in the item providing system 1d, it is possible to reduce processing of the display device 200d.

Note that, the item acquisition unit 324 of the mobile terminal 300d requests the item storage location information to the display device 200d at step S91, but the item acquisition unit 324 is not limited to such a configuration and may be configured to request at least one of a target item and a right to acquire the target item. When acquiring the target item, the item acquisition unit 324 may execute processing subsequent to step S13 described above. On the other hand, when acquiring the right to acquire the target item, the item acquisition unit 324 may execute processing subsequent to step S94.

Embodiment 8

Although an example in which one of the servers 100 to 100d is used has been described in each of the aforementioned embodiments, the respective functions of the servers 100 to 100d may be realized by individual servers. When a plurality of servers are applied, each of the servers may be managed by the same operator or may be managed by different operators.

CONCLUSION

A server (100 to 100d) according to an aspect 1 of the invention includes: an image output unit (124) that outputs, to a display device, an item presentation image indicating one or more items; and an acquisition unit (information acquisition unit 121) that acquires acquisition operation receiving information indicating that the display device has received an acquisition operation that is an operation of acquiring at least one of a target item of the one or more items and a right to acquire the target item, in which when the acquisition unit acquires the acquisition operation receiving information, the image output unit outputs an item acquisition complete image indicating that at least one of the target item and the right to acquire the target item has been acquired.

According to the aforementioned configuration, the server outputs, to the display device, the item presentation image indicating one or more items and acquires the acquisition operation information indicating that the acquisition operation that is an operation of acquiring at least one of the target item of the one or more items and the right to acquire the target item has been received. Upon acquisition of the acquisition operation information, the server 100 outputs an item acquisition complete image. For example, the server outputs, as the item acquisition complete image, an item presentation image that does not include the acquired item. Thus, the server changes an image that has been presented to a user to an image that does not include the item acquired by the user, so that it is possible to intuitively notify the user that the item has been acquired.

In a server according to an aspect 2 of the invention, in the aspect 1, the acquisition unit may further acquire selected item information indicating which item is selected from the one or more items indicated by the item presentation image, and when the acquisition unit acquires the selected item information, the image output unit may output an item selection complete image indicating that the item indicated by the selected item information is selected.

According to the aforementioned configuration, the server acquires the selected item information indicating the selected item and outputs the item selection complete image to the display device. For example, the server displays, as the item selection complete image, an item presentation image in which the selected item is highlighted. Thus, the server is able to intuitively notify the user that which item is selected.

In a server according to an aspect 3 of the invention, in the aspect 1 or 2, the acquisition unit may further acquire cancel information indicating that acquisition of at least one of the target item and the right to acquire the target item is to be canceled, and when the acquisition unit acquires the cancel information, the image output unit may output the item presentation image.

According to the aforementioned configuration, the server acquires the cancel information indicating that acquisition of the item is to be canceled and outputs the item presentation image. Thus, the server changes an image to be presented to the user from the item acquisition complete image to the item presentation image, so that it is possible to intuitively notify the user that the acquisition of the item is canceled.

In a server according to an aspect 4 of the invention, in any of the aspects 1 to 3, the acquisition operation receiving information acquired by the acquisition unit may be acquisition operation receiving information indicating that the display device (200 to 200d) including an antenna (NFC antenna 250) that performs near field radio communication with a mobile terminal (300 to 300d) has received the acquisition operation through the near field radio communication.

According to the aforementioned configuration, the server acquires the acquisition operation receiving information indicating that the acquisition operation has been received by performing the near field radio communication. Thus, the server enables the user to acquire a target item without requiring an unintuitive operation, such as pressing of a button, to acquire the target item.

In a server according to an aspect 5 of the invention, in the aspect 4, the acquisition operation may be an operation in which the mobile terminal is displaced from the antenna after the mobile terminal has been in proximity to the antenna.

According to the aforementioned configuration, the server enables the user to acquire a target item without requiring a troublesome operation.
