Several examples of second events are provided below, but the second events are not limited to these.

[0035] The second event may include a weight error. Here, a weight error refers to an error that occurs even when the operator performs the correct operation. For example, this error occurs when the total weight of multiple identical products falls outside the weight range set based on the number of products. For example, assume that five identical fruits are registered. If the total weight of the five registered identical fruits falls outside the weight range set for the number of fruits (five), a weight error occurs. For example, the attendant's response to the weight error is to input a command to clear the error via a terminal such as attendant terminal 30.

[0036] The second event may include the registration of an age-restricted product. An age-restricted product is, for example, a product that is prohibited from being sold to people under the age of 20, known as a "20-year-old prohibited product." For example, an age-restricted product is alcohol or tobacco. For example, the attendant's response to the registration of the age-restricted product is to input permission for the registration of the age-restricted product via a terminal such as attendant terminal 30 based on the attendant's confirmation of the customer.

[0037] The second event may include registration of a product related to the Pharmaceutical Affairs Law. For example, the product related to the Pharmaceutical Affairs Law is a pharmaceutical product. The attendant's response to the registration of the product related to the Pharmaceutical Affairs Law may be to contact an appropriate person according to the classification of the pharmaceutical product who can determine whether or not to approve the registration of the product related to the Pharmaceutical Affairs Law.

[0038] The communication unit 1012 communicates with the attendant terminal 30 via the communication interface 104.

When displaying two or more POS terminal objects on the display device 305, the display control unit 3012 displays the two or more POS terminal objects on the display device 305 in a manner that makes it possible to identify the priority order of the two or more self-service POS terminals 10 based on events of the two or more self-service POS terminals 10.

[0056] The priority order is the order in which events require an attendant's attention. The priority order includes a hierarchy established according to the events of the self-service POS terminal 10. For example, the hierarchy is the importance. The importance may be set appropriately based on various factors, such as the importance or urgency of the event requiring an attendant's attention and the attendant's response efficiency. As the importance decreases, the impact on the customer's operation of the self-service POS terminal 10 decreases even if the attendant's response is postponed. The importance is explained using three levels of importance, "high," "medium," and "low," in descending order, but the number of levels is not limited to these. For example, a call request is considered to have a "high" importance level. A call request is an active request by a customer, and the attendant cannot understand the customer's inquiry unless the call is initiated. Therefore, a call request has the highest importance level. A weight error is considered to have a "medium" importance level. An age-restricted product is considered to have a "low" importance level. A registration of a product related to the Pharmaceutical Affairs Act is considered to have a "low" importance level. A request for return of goods due to cancellation of registration is set to a "low" level of importance. A request for return of goods after payment is set to a "low" level of importance. The auxiliary storage device 303 may store data indicating the relationship between events of the self-service POS terminal 10 and the level of importance. The data indicating the relationship between events of the self-service POS terminal 10 and the level of importance may be updated as appropriate. The priority order of multiple POS terminal objects with the same level of importance may include the order of oldest reception time of the event signal by the communication unit 3011.

[0057] The manner in which the priority order of two or more self-service POS terminals 10 can be identified includes a manner in which the priority order can be identified by the arrangement of two or more POS terminal objects. The arrangement of two or more POS terminal objects includes an arrangement of two or more POS terminal objects. In this example, the display control unit 3012 displays two or more POS terminal objects on the display device 305 in an arrangement based on events of the two or more self-service POS terminals 10. Note that the manner in which the priority order of two or more self-service POS terminals 10 can be identified is not limited to the arrangement of two or more POS terminal objects. The manner in which the priority order of two or more self-service POS terminals 10 can be identified may include a manner in which the priority order can be identified by the appearance, such as the color or size, of the two or more POS terminal objects.

[0058] The POS terminal object includes various information. The POS terminal object may include identification information, such as the name of the self-service POS terminal 10 that transmitted the event signal to the attendant terminal 30. The POS terminal object may include the time the event signal was received by the communication unit 3011. The POS terminal object may include the importance of the event identified in the event signal. The POS terminal object may include the event identified in the event signal. The POS terminal object may include an input key for inputting a response instruction. The POS terminal object may include an input key for inputting a call start instruction as a response instruction. The POS terminal object may include an input key for inputting a call start hold instruction as a response instruction. The POS terminal object may or may not include an input key for inputting a response instruction depending on the event identified in the event signal. This is because the need for the attendant to speak with the customer changes depending on the event at the self-service POS terminal 10. If the event at the self-service POS terminal 10 is a call request, the attendant needs to speak with the customer. In this example, the POS terminal object includes an input key for inputting a response instruction. If the event at the self-service POS terminal 10 is a weight error, there is little need for the attendant to speak with the customer. In this example, the POS terminal object may not include an input key for inputting a response instruction. The attendant terminal 30 may receive multiple event signals from one self-service POS terminal 10 at the same or different times. In this example, the POS terminal object may include information for each event signal. The display control unit 3012 may set a priority order for the POS terminal objects based on the highest importance level among multiple importance levels for each event.

[0059] The display control unit 3012 displays a captured image related to the target self-service POS terminal. For example, the captured image related to the target self-service POS terminal is a captured image acquired by the camera 20 associated with the target self-service POS terminal. The display control unit 3012 displays the captured image on a display device that is the same as or different from the display device 305 that displays the POS terminal object. The display control unit 3012 can display the captured image together with the POS terminal object on the display device 305. The display control unit 3012 can display the captured image on a display device that is different from the display device 305 and that is usable by the attendant. Here, an example in which the display control unit 3012 displays the captured image on the display device 305 will be described.

[0060] The target self-service POS terminal is a self-service POS terminal 10 that is the target of the attendant's action. The target self-service POS terminal is a self-service POS terminal 10 selected from two or more self-service POS terminals 10 that display POS terminal objects. The target self-service POS terminal is selected based on an instruction to select the target self-service POS terminal input by the attendant via the input device 306. The instruction to select the target self-service POS terminal may include the above-mentioned instruction to start a call. The cameras 20 associated with the target self-service POS terminal are one or more cameras 20 that capture images of an area associated with the target self-service POS terminal. The cameras 20 associated with the target self-service POS terminal include a camera 20 that captures images of a customer using the target self-service POS terminal. The cameras 20 associated with the target self-service POS terminal include a camera 20 that captures images of an area associated with the target self-service POS terminal for returns following registration cancellation. The cameras 20 associated with the target self-service POS terminal include a camera 20 that captures images of an area associated with the target self-service POS terminal for returns after payment.

[0061] The display control unit 3012 erases the display of the POS terminal object based on the input of an erase instruction by the attendant via the input device 306. The erase instruction is an instruction to erase the display of the POS terminal object. The erasure includes transitioning from a display state to a non-display state. The erase instruction may include a call end instruction input by the attendant via the input device 306 after the call start instruction. The call end instruction is an instruction to end the started call. The erase instruction may be an instruction to erase the captured image in addition to erasing the POS terminal object. In this example, the display control unit 3012 erases the display of the captured image based on the input of the erase instruction via the input device 306. The attendant can input an instruction to erase the POS terminal object indicating the self-service POS terminal 10 that has been dealt with via the input device 306.

[0062] (Display example) An example of an image displayed on the self-service POS terminal 10 will be described. The first image will be described. The first image includes a plurality of display areas. The display areas are areas that display common content. The display areas may be areas that are explicitly framed, or may be virtual areas that are not explicitly framed.

[0063] 4 is a diagram showing an example of a display of the first image 51 on the self-checkout POS terminal 10. The display device 105 displays the first image 51. The first image 51 includes a plurality of display areas 601-606.

[0064] Display area 601 is an area for displaying a message to the customer. Display area 602 is an area for displaying details of each of one or more registered products. The details may include the product name, number of items, and price. Display area 603 is an area for displaying the total number of items and total price of one or more registered products. Display area 604 is an area for displaying input keys for inputting an instruction to request a call. Display area 605 is an area for displaying input keys for inputting an instruction to transition the image displayed on display device 105 from the image at the registration stage to the image at the checkout stage. Display area 606 is an area for displaying one or more input keys for registering products that do not have a code symbol attached.

[0065] The second image will now be described. In one example, the second image includes a plurality of display areas different from the call display area. The plurality of display areas included in the second image are a part or all of the plurality of display areas. The position and shape of each of the plurality of display areas included in the second image are the same as the position and shape of the corresponding display area included in the first image. The second image is an image in which the call display area is superimposed on at least one display area of ​​the plurality of display areas included in the first image. The call display area may overlap the entirety of at least one display area, or may overlap a part of at least one display area.

[0066] 5 is a diagram showing an example of the display of the second image 52 on the self-checkout POS terminal 10. The display device 105 displays the second image 52. The second image 52 includes a plurality of display areas 611 to 615 and a call display area 61.

[0067] The plurality of display areas 611 to 615 are areas corresponding to the plurality of display areas 601 to 605, which are part of the plurality of display areas 601 to 606. The plurality of display areas 611 to 615 are areas that display the same content as the plurality of display areas 601 to 605. The position and shape of each of the plurality of display areas 611 to 615 are the same as the position and shape of each of the plurality of display areas 601 to 605.

[0068] The second image 52 is an image in which a call display area 61 is superimposed on a display area 606 out of the plurality of display areas 601 to 606 included in the first image 51. The call display area 61 overlaps the entire display area 606 in the first image 51. In the second image 52, the call display area 61 is visible instead of the display area 606. Note that the call display area 61 may be set to overlap with a portion of the display area 606 in the first image 51. In this example, the second image 52 includes a portion of the display area 606 that is not overlapped with the call display area 61 and is visible.

[0069] The at least one display area on which the call display area 61 is superimposed is not limited. It is preferable that the call display area 61 be superimposed on a display area that displays information that is less necessary during a call with an attendant. The display area 606 that displays one or more input keys is an example of a display area that displays information that is less necessary during a call with an attendant. The display area 612 that displays details displays information that the customer may refer to during a call with an attendant. The display area 612 that displays details is an example of a display area that displays information that is highly necessary.

[0070] In another example, the second image includes multiple display areas different from the call display area. The multiple display areas included in the second image are part or all of the multiple display areas. The appearance of at least one display area among the multiple display areas included in the second image is different from the appearance of a corresponding display area included in the first image. The appearance of the display area may be a display appearance including at least one of a position and a shape. The second image is an image in which the appearance of at least one display area among the multiple display areas included in the first image is changed. Changing the appearance of the at least one display area includes changing the appearance of the at least one display area to set the call display area. For example, the call display area is an area set so as not to overlap with the multiple display areas included in the second image. The call display area may be superimposed on part of the multiple display areas included in the second image. Changing the appearance of the at least one display area includes shrinking the at least one display area. Changing the appearance of the at least one display area includes moving the position of the at least one display area.

[0071] FIG. 6 is a diagram showing another example of the display of the second image 53 on the self-checkout POS terminal 10. In FIG. The display device 105 displays the second image 53 . The second image 53 includes a plurality of display areas 621 to 626 and a call display area 62.

[0072] The plurality of display areas 621 to 626 correspond to all of the plurality of display areas 601 to 606. The plurality of display areas 621 to 626 display the same content as the plurality of display areas 601 to 606. The position and shape of each of the plurality of display areas 621, 623 to 626 are the same as the position and shape of each of the plurality of display areas 601, 603 to 605. The shape of display area 622 is a shape obtained by reducing the shape of display area 602 in the horizontal direction, and therefore the appearance of display area 622 is different from the appearance of display area 602. Second image 53 is an image obtained by changing the appearance of display area 602, one of the plurality of display areas 601 to 606. Call display area 62 is an area set in an area not included in any of the plurality of display areas 621 to 626, which is generated by reducing display area 602 to display area 622. In the second image 53, the call display area 62 is visible together with the plurality of display areas 621 to 626.

[0073] Note that the first image 51, the second image 52, and the second image 53 shown in FIGS. 4 to 6 are examples of images at the product registration stage, but the display device 105 can similarly display the first image or the second image at the checkout stage. For example, the display device 105 displays the first image at the checkout stage based on the selection of the checkout button in the image at the product registration stage. The first image at the checkout stage includes a display of the total price and the payment amount, as well as a display of a "call a clerk" input key (icon) for inputting an instruction to request a call. The display device 105 displays the second image at the checkout stage based on the selection of the "call a clerk" input key in the first image at the checkout stage. The second image at the checkout stage includes a display of the total price and the payment amount, as well as a call display area. The second image at the checkout stage is an image displayed when a return is requested after payment.

[0074] An example of an image displayed on the attendant terminal 30 will be described. FIG. 7 is a diagram showing a display example on the attendant terminal 30. As shown in FIG. The display control unit 3012 displays three POS terminal objects 71 to 73 on the display device 305. The POS terminal object 71 includes identification information "self POS terminal K." The POS terminal object 71 includes a reception time of "16:40." The POS terminal object 71 includes an importance level of "high." The POS terminal object 71 includes an event of "store clerk call." The event of "store clerk call" corresponds to a call request. The POS terminal object 71 includes multiple input keys for inputting response instructions. The POS terminal object 71 includes an input key 81 for inputting a call start instruction as a response instruction. The POS terminal object 71 includes an input key 82 for inputting a call start hold instruction as a response instruction. The POS terminal objects 72 and 73 include various information, similar to the POS terminal object 71.

[0075] The importance indicated by the POS terminal object 71 is higher than the importance indicated by the POS terminal object 72 and the POS terminal object 73. The importance indicated by the POS terminal object 72 and the POS terminal object 73 are the same. The reception time indicated by the POS terminal object 72 is older than the reception time indicated by the POS terminal object 73. The order of priority is "self POS terminal K" indicated by the POS terminal object 71, "self POS terminal B" indicated by the POS terminal object 72, and "self POS terminal R" indicated by the POS terminal object 73. The display control unit 3012 displays the POS terminal object 71, POS terminal object 72, and POS terminal object 73 in this order horizontally from the left on the display device 305.

[0076] FIG. 8 is a diagram showing another example of a display on the attendant terminal 30. In FIG. FIG. 8 shows an example in which a POS terminal object 74 is displayed on the display device 305 in addition to the three POS terminal objects 71 to 73 shown in FIG. It is assumed that the communication unit 3011 receives the event signal from the self POS terminal 10 identified as "self POS terminal D." It is assumed that the displays of the three POS terminal objects 71 to 73 have not been erased.

[0077] The display control unit 3012 updates the priority order of the four self POS terminals 10 based on the acquisition of an event signal from "self POS terminal D" by the communication unit 3011. The importance indicated in the POS terminal object 74 is lower than the importance indicated in the POS terminal object 71. The importance indicated in the POS terminal object 74 is higher than the importance indicated in the POS terminal objects 72 and 73. The priority order is "self POS terminal K" indicated in the POS terminal object 71, "self POS terminal D" indicated in the POS terminal object 74, "self POS terminal B" indicated in the POS terminal object 72, and "self POS terminal R" indicated in the POS terminal object 73. The display control unit 3012 displays the POS terminal object 71, POS terminal object 74, POS terminal object 72, and POS terminal object 73 in this order horizontally from the left on the display device 305.

[0078] FIG. 9 is a diagram showing yet another example of a display on the attendant terminal 30. In FIG. It is assumed that the attendant has input a call start instruction via the input device 306 by selecting the input key 81 shown on the POS terminal object 71. The target self-service POS terminal is "self-service POS terminal K."

[0079] The communication unit 3011 receives captured image data acquired by the camera 20 associated with the "self-service POS terminal K." For example, the captured image data is data including the face of a customer using the "self-service POS terminal K." The display control unit 3012 displays a captured image 91 based on the captured image data acquired by the camera 20 associated with the "self-service POS terminal K" on the display device 305. The captured image 91 is a real-time image taken during a call, including the face of a customer using the "self-service POS terminal K."

[0080] (Example of operation) Next, an example of the operation of the checkout system 100 configured as described above will be described. Note that the processing procedure described below is merely an example, and each process may be modified as much as possible. Furthermore, steps in the processing procedure described below may be omitted, replaced, or added as appropriate depending on the embodiment.

[0081] The operation of the self-checkout POS terminal 10 will be described. 10 is a flowchart illustrating the processing in the self-service POS terminal 10. It is assumed that the display device 105 displays a first image.

[0082] The detection unit 1011 detects an event of the self-checkout POS terminal 10 (ACT1). The communication unit 1012 transmits an event signal to the attendant terminal 30 based on the detection of an event in the self-service POS terminal 10 by the detection unit 1011 (ACT2). The communication unit 1012 receives the response signal from the attendant terminal 30 (ACT3).

[0083] The display control unit 1013 displays the second image on the display device 105 based on the response signal (ACT4). In ACT4, for example, the display control unit 1013 transitions the image displayed on the display device 105 from the first image to the second image based on the reception of the response signal by the communication unit 1012.

[0084] If the response signal is a signal regarding the call initiation being put on hold, the display control unit 1013 displays an image indicating that the call is being put on hold in the call display area. If the response signal is a signal regarding the call initiation, the display control unit 1013 displays an image indicating that the call is being held in the call display area. During the call, the communication unit 1012 transmits audio data based on audio input via the microphone 112 of the self-service POS terminal 10 to the attendant terminal 30. During the call, the communication unit 1012 receives audio data based on audio input via the microphone 309 of the attendant terminal 30 from the attendant terminal 30. The speaker 111 outputs audio based on the audio data received by the communication unit 1012. During the call, the communication unit 1012 may also receive captured image data acquired by the camera 307 of the attendant terminal 30 from the attendant terminal 30. The display control unit 1013 displays a captured image based on the captured image data received by the communication unit 1012 in the call display area.

[0085] Note that the communication unit 1012 may receive a signal regarding the start of a call after receiving a signal regarding the call start being put on hold. In this example, the display control unit 1013 transitions the image displayed in the call display area from an image during the call start being put on hold to an image during the call, based on the reception of the signal regarding the call start by the communication unit 1012.

[0086] The display control unit 1013 determines whether to end the call (ACT6). In ACT6, for example, the display control unit 1013 may determine to end the call based on the customer inputting an instruction to end the call via the input device 106. The display control unit 1013 may determine to end the call based on the communication unit 1012 receiving a signal regarding the end of the call from the attendant terminal 30. The signal regarding the end of the call is a signal based on the instruction to end the call input by the attendant via the input device 306. If the display control unit 1013 does not determine to end the call (ACT5, NO), it repeats the processing of ACT5. If the display control unit 1013 determines to end the call (ACT5, YES), the processing transitions from ACT5 to ACT6.

[0087] When the call is ended, the display control unit 1013 displays the first image on the display device 105 (ACT7). In ACT7, for example, the display control unit 1013 transitions the image displayed on the display device 105 from the second image to the first image.

[0088] Note that the event identified by the event signal transmitted to the attendant terminal 30 by the communication unit 1012 in ACT2 may not require a call. In this example, the processes of ACT3 to ACT6 may be omitted. Note that the detection unit 1011 may detect multiple events at the same or different times. In this example, the processes of ACT1 to ACT2 are repeated multiple times.

[0089] The operation of the attendant terminal 30 will now be described. FIG. 11 is a flowchart showing an example of a display process in the attendant terminal 30. Each time the attendant terminal 30 receives an event signal, it executes the process exemplified below.

[0090] The communication unit 3011 receives an event signal from the self POS terminal 10 (ACT11). The display control unit 3012 displays a POS terminal object on the display device 305 based on the event signal (ACT12). A case will be described where the display device 305 is not displaying a POS terminal object. In this example, the only POS terminal object to be displayed is a new POS terminal object based on the event signal received by the communication unit 3011. The display control unit 3012 displays the new POS terminal object based on the event signal on the display device 305 based on the reception of the event signal by the communication unit 3011.

[0091] A case will be described in which the display device 305 displays one or more POS terminal objects. In this example, the POS terminal objects to be displayed are two or more POS terminal objects, including one or more POS terminal objects currently displayed on the display device 305 and a new POS terminal object based on an event signal received by the communication unit 3011. Based on the reception of the event signal by the communication unit 3011, the display control unit 3012 updates the priority order of two or more self-service POS terminals 10, including the self-service POS terminal 10 that is the sender of the event signal. Based on the updated priority order, the display control unit 3012 displays two or more POS terminal objects, including the new POS terminal object, on the display device 305. The display control unit 3012 displays two or more POS terminal objects on the display device 305 in a manner that makes it possible to identify the priority order of the two or more self-service POS terminals 10. For example, the display control unit 3012 rearranges the order of the two or more POS terminal objects according to the order of priority. The display control unit 3012 displays two or more POS terminal objects on the display device 305 in an order based on the events of the two or more self-service POS terminals 10.

[0092] FIG. 12 is a flowchart showing another example of the display process in the attendant terminal 30.

[0093] The display control unit 3012 detects the selection of the target self-service POS terminal (ACT21). In ACT21, for example, the display control unit 3012 detects the selection of the target self-service POS terminal based on an instruction to select the target self-service POS terminal input via the input device 306.

[0094] The display control unit 3012 displays on the display device 305 a captured image based on the captured image data acquired by the camera 20 associated with the target self-service POS terminal (ACT22). In ACT22, for example, the communication unit 3011 receives the captured image data acquired by the camera 20 associated with the target self-service POS terminal. The display control unit 3012 displays on the display device 305 a captured image based on the captured image data received by the communication unit 3011.

[0095] The display control unit 3012 may display on the display device 305 an image captured under shooting conditions according to an event at the target self-service POS terminal. The shooting conditions are conditions related to shooting by the camera 20 that acquires the captured image data. The shooting conditions may include a shooting range. The shooting range is the range that is captured by the camera 20. The range that is captured includes the subject that is being captured. The shooting conditions may include a shooting time. The shooting time is the timing at which the image is captured by the camera 20. The timing at which the image is captured may be any length of time including real time or a point in the past. The shooting conditions may be a combination of a shooting range and a shooting time.

[0096] A case where the event of the self-service POS terminal 10 is a "call to a store clerk," that is, a request for a "call" will be described. The photographing range may be a range that includes the face of the customer using the target self-service POS terminal. The photographing time may be real time. This allows the attendant to appropriately talk to the customer while seeing the customer's face in real time.

[0097] A case where the event at the self-service POS terminal 10 is a weight error will be described. The photographing range may be a range that includes the hands of the customer using the target self-service POS terminal. The photographing time may be any length of time that includes the time when the event signal corresponding to the time when the event occurred is received by the attendant terminal 30. This allows the attendant to appropriately determine whether or not the error needs to be resolved by checking the hands of the customer at the time when the weight error occurred.

[0098] A case where the event at the self-service POS terminal 10 is the registration of an age-restricted product will be described. The photographed range may be an area that includes the face of the customer using the self-service POS terminal. The photographed time may be real time. This allows the attendant to check the face of the customer who has registered the age-restricted product and appropriately determine whether or not to allow the registration of the age-restricted product.

[0099] A case will be described where the event at the self-service POS terminal 10 is a request for return of goods due to registration cancellation. The photographing range may be an area that includes the product storage area for returns due to registration cancellation associated with the target self-service POS terminal. The photographing time may be real time. This allows the attendant to check the status of the product storage area in real time and determine whether the customer is properly returning goods due to registration cancellation.

[0100] A case where the event at the self-service POS terminal 10 is a request for a return of a product after payment will be described. The photographing range may be an area that includes the product storage area for returns after payment associated with the target self-service POS terminal. The photographing time may be real time. This allows the attendant to check the status of the product storage area in real time and determine whether the customer is properly returning the product after payment.

[0101] When the shooting time is real time, the display control unit 3012 displays on the display device 305 a captured image based on real time captured image data received by the communication unit 3011. When the shooting time is past time, the display control unit 3012 displays on the display device 305 a captured image based on past captured image data received by the communication unit 3011. In this example, the auxiliary storage device 303 may store past captured image data received by the communication unit 3011.

[0102] During a call, the communication unit 3011 receives, from the self-service POS terminal 10, voice data based on the voice input via the microphone 112 of the self-service POS terminal 10. The speaker 308 outputs voice based on the voice data received by the communication unit 3011. During a call, the communication unit 3011 transmits voice data based on the voice input via the microphone 309 of the attendant terminal 30 to the self-service POS terminal 10. During a call, the communication unit 3011 may also transmit photographed image data acquired by the camera 307 of the attendant terminal 30 to the self-service POS terminal 10.

[0103] The display control unit 3012 determines whether to delete the POS terminal object related to the target self POS terminal (ACT23). In ACT23, for example, the display control unit 3012 may determine to delete the POS terminal object related to the target self POS terminal based on a deletion instruction input via the input device 306. If the display control unit 1013 does not determine to delete the POS terminal object (ACT23, NO), it repeats the processing of ACT23. If the display control unit 1013 determines to delete the POS terminal object (ACT23, YES), the processing transitions from ACT23 to ACT24.

[0104] The display control unit 3012 erases the display of the captured image based on the input of an erase instruction via the input device 306 (ACT24). The display control unit 3012 erases the display of the POS terminal object related to the target self-service POS terminal based on the input of the erase instruction via the input device 306 (ACT25). The display control unit 3012 displays one or more POS terminal objects that continue to be displayed on the display device 305 in a manner that fills the space occupied by the erased POS terminal object.

[0106] (effect) A display processing device according to an embodiment receives a signal related to an event of a transaction support device. The display processing device displays an object representing the transaction support device on a display based on the signal related to the event of the transaction support device. When displaying multiple objects representing multiple transaction support devices on a display, the display processing device displays the multiple objects on a display in a manner that allows the priority of the multiple transaction support devices to be identified based on the events of the multiple transaction support devices. In this manner, the display processing device displays the multiple objects in a manner that allows the priority of the multiple transaction support devices to be identified, thereby enabling a clear display of the order of handling. Because the priority of the multiple transaction support devices is based on the events of the multiple transaction support devices, the display processing device can display the multiple objects in the order in which handling is required. Since attendants can grasp the order in which handling is required for the multiple transaction support devices, they can efficiently handle the multiple transaction support devices. This enables a small number of attendants to monitor a large number of transaction support devices. As a result, the display processing device can help improve the efficiency of attendants in handling the transaction support devices.

[0107] The display processing device displays the plurality of objects on a display in an order based on events of the plurality of transaction supporting devices. In this way, the display processing device displays a plurality of objects in order of priority of a plurality of transaction support devices, so that the display can be made in a manner that makes it easy to understand the order of handling.

[0108] The display processing device displays the captured image of a transaction support device selected from the plurality of transaction support devices on the same display or a different display. In this way, the display processing device can support the selected transaction support device in dealing with the issue by displaying the captured image. The attendant can appropriately deal with the event at the transaction support device by viewing the captured image. In this way, the display processing device can support the attendant in improving the efficiency with which the attendant deals with the transaction support device.

[0109] The display processing device displays the captured image under the capture conditions corresponding to the event of the selected transaction support device. In this way, the display processing device can display the captured image according to the event that the attendant needs to check, and the attendant can efficiently deal with the event of the transaction assistance device because the attendant can see the captured image that needs to be checked in response to the event of the transaction assistance device.

[0110] A trading assistance device according to an embodiment transmits a signal related to a call request between a user of the trading assistance device and a user of an electronic device different from the trading assistance device. The trading assistance device receives a response to the signal related to the call request. The trading assistance device displays a first image on a display that does not include a display area related to the call. Based on the response, the trading assistance device displays a second image on a display that includes a display area related to the call. In this way, the display processing device allows the attendant to talk to the customer while displaying the call-related display area. The attendant can handle customer inquiries by phone without visiting the customer. This allows the display processing device to help the attendant improve the efficiency with which the transaction support device is handled. Furthermore, the display processing device switches between displaying and hiding the call-related display area, so it does not impair the usability of the transaction support device for customers. By displaying the call-related display area, the display processing device can show the customer an image of the attendant, giving the customer a sense of security.

[0111] The first image includes a plurality of display areas, and the second image is an image in which a display area related to a call is superimposed on at least one of the plurality of display areas. In this way, the transaction assistance device displays the call-related display area in an overlapping manner without changing the appearance of multiple display areas, thereby enabling the display area related to the call to be displayed without imposing a processing load. For example, the transaction assistance device overlaps the call-related display area with a display area that displays information less necessary during a call with an attendant, thereby preventing the hiding of information that the customer may see during the call. Therefore, the transaction assistance device does not impair the customer's usability of the transaction assistance device.

[0112] The first image includes a plurality of display areas, and the second image is an image in which the aspect of at least one of the plurality of display areas is changed. In this way, the transaction assistance device can display the call-related display area without hiding any of the multiple display areas that were displayed before the call-related display area was displayed. Since the amount of information displayed on the transaction assistance device is hardly reduced even when the call-related display area is displayed, the customer can talk to the attendant while viewing the necessary information.

[0113] [Other embodiments] Although an example has been described in which the self-service POS terminal 10 displays a display area related to a call on the display device 105, the present invention is not limited to this. The display control unit 1013 may display the display area related to a call on a display device different from the display device 105 that displays the first image. The display device different from the display device 105 is a display device that can be used by a customer. The display device different from the display device 105 may be included in the self-service POS terminal 10 or may be separate from the self-service POS terminal 10. In this example, the display control unit 1013 displays the display area related to a call on a display device different from the display device 105 based on reception of a response signal by the communication unit 1012. The display control unit 1013 does not need to transition the image displayed on the display device 105 from the first image to the second image based on reception of a response signal by the communication unit 1012.

[0114] The transaction support device may be realized by a single device such as the self-service POS terminal 10, or may be realized by multiple devices with distributed functions. The display processing device may be realized by a single device such as the attendant terminal 30, or may be realized by multiple devices with distributed functions.

[0115] The program may be transferred in a state where it is stored in an electronic device, or in a state where it is not stored in an electronic device. In the latter case, the program may be transferred via a network, or in a state where it is recorded on a recording medium. The recording medium is a non-transitory tangible medium. The recording medium is a computer-readable medium. The form of the recording medium is not important as long as it is a medium that can store the program and is computer-readable, such as a CD-ROM or a memory card.
