[0051] [Entertainment Features] The self-checkout system 100 is equipped with entertainment functions. For example, the buyer communication terminal 10 can output images and sounds of any character to provide a fun shopping experience for families. The entertainment functions are described below. Requests and other communications transmitted from the buyer communication terminal 10 include the terminal identification information of the buyer communication terminal 10. The information processing server 20 identifies the communication partner's terminal from the terminal identification information included in the requests and other communications transmitted from the buyer communication terminal 10.

[0052] • Character output function (top screen) Figure 10 is a sequence diagram showing an example of the character output function (top screen). Figure 11 is an example of a screen (top screen) containing an image of a predetermined character.

[0053] For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the output settings for the image and sound of a predetermined character, according to the output settings for the image and sound of the predetermined character received by the input / output device 552 (ACT 11). The processor 21 of the information processing server 20 stores the output settings for the image and sound of the predetermined character in the main memory 22, etc. (ACT 12). The predetermined character may be a popular character, a character for children, a character of the company that has implemented the system, or a character of the region where the system has been implemented.

[0054] The buyer communication terminal 10 communicates with the information processing server 20 via the communication interface 14, and the processor 11 of the buyer communication terminal 10 performs authentication processing (ACT 15). For example, the buyer communication terminal 10 sends an authentication request containing the buyer communication terminal 10's terminal identification information to the information processing server 20 via the communication interface 14 (ACT 16). The information processing server 20 receives the authentication request via the communication interface 25. The processor 21 of the information processing server 20 determines that authentication is successful if the terminal identification information included in the received authentication request matches the terminal identification information registered in advance. The information processing server 20 sends an authentication completion notification to the buyer communication terminal 10 via the communication interface 25 indicating that authentication was successful (ACT 17). The buyer communication terminal 10 receives the authentication completion notification via the communication interface 14 and terminates the authentication process.

[0055] Next, the information processing server 20 transmits display information for screen 1001 (top screen) including an image of a predetermined character via the communication interface 25 (ACT 18). The buyer communication terminal 10 receives the display information for screen 1001 via the communication interface 14. The buyer communication terminal 10 displays screen 1001 including an image of a predetermined character via the input / output device 1523 (ACT 19). The image of the predetermined character may be a still image or a moving image. In addition to the image of the predetermined character, screen 1001 includes various operation buttons.

[0056] In addition, the buyer communication terminal 10 may store multiple still image files and video files of a predetermined character in its external memory 53, and the processor 51 may select and output one or more files from the multiple still image files and video files in response to an operation input detected by the input / output device 152.

[0057] When the buyer communication terminal 10 detects touch input to the screen 1001 via the input / output device 1523, the processor 11 executes a function corresponding to the touch input. For example, when the buyer communication terminal 10 detects an operation input to select a character image (ACT20), it sends a request corresponding to the touch input to the information processing server 20 (ACT21). Based on the request corresponding to the operation input, the information processing server 20 sends the character's voice to the buyer communication terminal 10 (ACT22). The buyer communication terminal 10 outputs the character's voice via the input / output device 1523 (ACT23). The character's voice is guidance to assist with shopping. For example, the character's voice is guidance to assist with product registration.

[0058] In addition, the buyer communication terminal 10 may store multiple voice files of a predetermined character in its external memory 53, and the processor 51 may select and output one or more files from the multiple voice files in response to an operation input detected by the input / output device 152.

[0059] The Self-Checkout System 100's character voice output function will make shopping more enjoyable for customers with children, leading to increased store usage and customer satisfaction.

[0060] • Function to switch guidance information according to the scanner. Figure 12 is a functional block diagram of the buyer communication terminal 10 for realizing a function to switch guidance information according to the scanner. As shown in Figure 12, the processor 11 includes a detection unit 111, a first output unit 112, an acquisition unit 113, and a second output unit 114.

[0061] Figure 13 is a functional block diagram of the information processing server 20 for realizing the guidance switching function according to the scanner. As shown in Figure 13, the processor 21 includes an acquisition unit 211, a determination unit 212, and an output unit 213.

[0062] First, let's explain the operation of the buyer communication terminal 10. When the first scanner 1521 reads product identification information such as a product code, the first device interface 1511 outputs first read information including first interface information and product identification information. Also, when the second scanner 1522 reads product identification information such as a product code, the second device interface 1512 outputs second read information including second interface information and product identification information.

[0063] The first interface information is information that identifies the first device interface 1511, or information such as the output format from the first device interface 1511, and indicates that the product identification information contained in the first read information was read by the first scanner 1521. Similarly, the second interface information is information that identifies the second device interface 1512, or information such as the output format from the second device interface 1512, and indicates that the product identification information contained in the second read information was read by the second scanner 1522.

[0064] Alternatively, the first scanner 1521 may output first reading information that includes the read product identification information and unique information of the first scanner 1521, and the first device interface 1511 may output first reading information that includes the read product identification information and unique information of the first scanner 1521. The unique information of the first scanner 1521 included in the first reading information indicates that the product identification information included in the same first reading information is information read by the first scanner 1521. Similarly, the second scanner 1522 may output second reading information that includes the read product identification information and unique information of the second scanner 1522, and the second device interface 1512 may output second reading information that includes the read product identification information and unique information of the second scanner 1522.

[0065] The detection unit 111 of the processor 11 detects the product identification information read by the first scanner 1521 included in the first reading information and the product identification information read by the second scanner 1522 included in the second reading information at different timings.

[0066] The detection unit 111 determines, based on the first interface information output from the first device interface 1511 to which the first scanner 1521 is connected, that the product identification information output from the first device interface 1511 corresponds to the information read by the first scanner 1521. In other words, the detection unit 111 determines, based on the first interface information included in the first read information, that the product identification information included in the same first read information is information read by the first scanner 1521.

[0067] Furthermore, the detection unit 111 determines, based on the second interface information output from the second device interface 1512 to which the second scanner 1522 is connected, that the product identification information output from the second device interface 1512 corresponds to the information read by the second scanner 1522. In other words, the detection unit 111 determines, based on the second interface information included in the second reading information, that the product identification information included in the same second reading information is information read by the second scanner 1522.

[0068] The first output unit 112 outputs a first product registration request containing product identification information read by the first scanner 1521 to the information processing server 20. For example, the first product registration request includes first interface information. The communication interface 14 transmits the first product registration request to the information processing server 20.

[0069] Furthermore, the first output unit 112 outputs a second product registration request to the information processing server 20, which includes product identification information read by the second scanner 1522. For example, the second product registration request includes second interface information. The communication interface 14 transmits the second product registration request to the information processing server 20.

[0070] Next, the operation of the information processing server 20 will be explained. The communication interface 25 receives the first product registration request and the second product registration request at different times. The acquisition unit 211 of the processor 21 acquires the first product registration request, which includes product identification information read by the first scanner 1521 of the buyer communication terminal 10, and the second product registration request, which includes product identification information read by the second scanner 1522 of the buyer communication terminal 10, at different times.

[0071] The determination unit 212 determines that the first product registration request corresponds to a request read by the first scanner 1521, and that the second product registration request corresponds to a request read by the second scanner 1522. For example, based on the first interface information included in the first product registration request, the determination unit 212 determines that the first product registration request corresponds to a request read by the first scanner 1521 connected to the first device interface 1511. Also, based on the second interface information included in the second product registration request, the determination unit 212 determines that the second product registration request corresponds to a request read by the second scanner 1522 connected to the second device interface 1512.

[0072] The output unit 213 outputs first guidance information to the buyer communication terminal 10 in response to the acquisition and determination result of the first product registration request. The communication interface 25 transmits the first guidance information to the buyer communication terminal 10. The output unit 213 also outputs second guidance information to the buyer communication terminal 10 in response to the acquisition and determination result of the second product registration request. The communication interface 25 transmits the second guidance information to the buyer communication terminal 10. The first guidance information includes at least image information, and the second guidance information includes at least audio information.

[0073] Let's explain the operation of the buyer communication terminal 10 again. The communication interface 14 receives the first guidance information transmitted from the information processing server 20 that received the first product registration request, and the second guidance information transmitted from the information processing server 20 that received the second product registration request, at different times. The acquisition unit 113 acquires the first guidance information and the second guidance information at different times. For example, the acquisition unit 113 acquires the first guidance information including image information, and the second guidance information including audio information.

[0074] The second output unit 114 outputs the first guidance information and the second guidance information at different timings. For example, the second output unit 114 outputs the image information included in the first guidance information to the touch panel display 15231 and outputs the audio information included in the second guidance information to the speaker 15232. The touch panel display 15231 displays the image information included in the first guidance information, and the speaker 15232 outputs the audio information included in the second guidance information.

[0075] For example, the first guidance information includes image information showing the product registration result or image information to support various operations. In addition, the first guidance information may also include audio information corresponding to the image information. Furthermore, the second guidance information includes audio information of a popular character to make shopping more enjoyable. In addition, the second guidance information may also include image information showing the product registration result or image information to support various operations.

[0076] Figure 14 is a sequence diagram showing an example of a function that switches guidance information according to the scanner. For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the output settings for the image and sound of a predetermined character, according to the output settings for the image and sound of a predetermined character received by the input / output device 552 (ACT31). The processor 21 of the information processing server 20 stores the output settings for the image and sound of the predetermined character in the main memory 22, etc. (ACT32).

[0077] When the buyer communication terminal 10 completes the authentication process, it displays screen 1001 and executes product registration mode according to the user's input. This enables the reading of product identification information by the first scanner 1521 and the second scanner 1522.

[0078] For example, when the first scanner 1521 reads product identification information (ACT33), the first device interface 1511 outputs first read information including first interface information and product identification information in response to the read. The detection unit 111 of the processor 11 detects the first read information. The first output unit 112 outputs a first product registration request including the first interface information and product identification information to the information processing server 20, and the communication interface 14 transmits the first product registration request to the information processing server 20 (ACT34).

[0079] The communication interface 25 of the information processing server 20 receives the first product registration request, and the acquisition unit 211 of the processor 21 acquires the first product registration request (ACT35). The determination unit 212 determines, based on the first interface information included in the first product registration request, that the first product registration request corresponds to a request read by the first scanner 1521 connected to the first device interface 1511 (ACT36). The output unit 213 outputs the first guidance information to the buyer communication terminal 10 in accordance with the acquisition and determination results of the first product registration request (ACT37). The communication interface 25 transmits the first guidance information to the buyer communication terminal 10 (ACT38).

[0080] The communication interface 14 of the buyer communication terminal 10 receives first guidance information transmitted from the information processing server 20 that received the first product registration request. The acquisition unit 113 of the processor 111 acquires the first guidance information. The second output unit 114 outputs the image information contained in the first guidance information to the touch panel display 15231. The touch panel display 15231 displays the image information contained in the first guidance information (ACT39).

[0081] If the first scanner 1521 continues to read product identification information, the operations of ACT33 to ACT39 are repeated.

[0082] When the second scanner 1522 reads product identification information (ACT40), the second device interface 1512 outputs second read information, including second interface information and product identification information, in response to the reading. The detection unit 111 of the processor 11 detects the second read information. The first output unit 112 outputs a second product registration request, including second interface information and product identification information, to the information processing server 20, and the communication interface 14 transmits the second product registration request to the information processing server 20 (ACT41).

[0083] The communication interface 25 of the information processing server 20 receives the second product registration request, and the acquisition unit 211 of the processor 21 acquires the second product registration request (ACT 42). The determination unit 212 determines, based on the second interface information included in the second product registration request, that the second product registration request corresponds to a request for reading by the second scanner 1522 connected to the second device interface 1512 (ACT 43). The output unit 213 outputs the second guidance information to the buyer communication terminal 10 in accordance with the acquisition and determination results of the second product registration request (ACT 44). The communication interface 25 transmits the second guidance information to the buyer communication terminal 10 (ACT 45).

[0084] The communication interface 14 of the buyer communication terminal 10 receives the second guidance information transmitted from the information processing server 20 that received the second product registration request. The acquisition unit 113 of the processor 111 acquires the second guidance information. The second output unit 114 outputs the audio information contained in the second guidance information to the speaker 15232. The speaker 15232 outputs the audio information contained in the second guidance information (ACT46).

[0085] For example, when a parent and child are shopping together, the parent and child can use different scanners to make shopping more enjoyable. For instance, when a parent uses the first scanner 1521 to read product identification information, the touch panel display 15231 displays the image information included in the first guidance information. When a child uses the second scanner 1522 to read product identification information, the speaker 15232 outputs the audio information included in the second guidance information.

[0086] The first type of guidance information includes image information showing the product registration results or image information to support various operations, allowing parents to shop smoothly. The second type of guidance information includes voice information from popular characters to make shopping more enjoyable, allowing children to stay engaged while shopping. In this way, parent-child shopping becomes more comfortable, and an increase in the number of items purchased can be expected.

[0087] • Output function for character voices, etc. (product registration screen) Figure 15 is a sequence diagram showing an example of the output function for character voices, etc. (product registration screen). Figures 16 to 18 are examples of product registration screens displayed on the touch panel display of the buyer communication terminal. Here, regardless of whether the product identification information is read by the first scanner 1521 or the second scanner 1522, an output function such as character voice is provided.

[0088] For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the output settings for the image and sound of a predetermined character, according to the output settings for the image and sound of a predetermined character received by the input / output device 552 (ACT 51). The processor 21 of the information processing server 20 stores the output settings for the image and sound of the predetermined character in the main memory 22, etc. (ACT 52).

[0089] When the processor 11 of the buyer communication terminal 10 completes the authentication process, the input / output device 1523 displays the screen 1001 shown in Figure 16. When the input / output device 1523 receives an input operation (selection to start shopping or character selection) via the screen 1001 (ACT 53), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT 54).

[0090] The communication interface 25 of the information processing server 20 receives a request corresponding to the input operation. The processor 21 selects guidance information corresponding to the input operation. For example, it selects image information and voice information of a character corresponding to the input operation. The communication interface 25 transmits the image information and voice information of the character corresponding to the input operation to the buyer communication terminal 10 (ACT 55).

[0091] The communication interface 14 of the buyer communication terminal 10 receives character image information and audio information corresponding to the input operation, and the input / output device 1523 transitions screen 1001 to screen 1002 and outputs character image information and audio information corresponding to the screen transition (ACT 56). The input / output device 1523 provides various information by outputting character image information and audio information corresponding to the input operation or screen transition, thereby providing an enjoyable shopping experience. After this, the input / output device 1523 continues to provide various information by outputting character image information and audio information corresponding to the input operation or screen transition as appropriate.

[0092] Furthermore, when the input / output device 1523 is displaying screen 1002 and the first scanner 1521 or the second scanner 1522 reads product identification information (ACT 57), the communication interface 14 sends a product registration request including the read product identification information to the information processing server 20 (ACT 58).

[0093] The communication interface 25 of the information processing server 20 receives a product registration request. The processor 21 registers the product identification information included in the product registration request and selects guidance information according to the registration result. For example, it selects character image information and voice information according to the registration result. The communication interface 25 transmits the character image information and voice information according to the registration result to the buyer communication terminal 10 (ACT59).

[0094] The communication interface 14 of the buyer communication terminal 10 receives image and sound information of a character corresponding to the registration result, and the input / output device 1523 transitions screen 1002 to screen 1003 as shown in Figure 17 and outputs image and sound information of a character corresponding to the registration result (ACT60). The input / output device 1523 provides various information by outputting image and sound information of a character corresponding to the registration result or screen transition, thereby providing an enjoyable shopping experience. For example, screen 1003 displays product registration information using standard-sized (first size) characters and symbols.

[0095] Similarly, the buyer communication terminal 10 reads the product identification information (ACT61)(ACT65) and sends a product registration request containing the read product identification information to the information processing server 20 (ACT62)(ACT66). The information processing server 20 registers the product identification information included in the product registration request and sends character image information and voice information corresponding to the registration result to the buyer communication terminal 10 (ACT63)(ACT67). The buyer communication terminal 10 transitions from screen 1002 to screen 1003 and outputs character image information and voice information corresponding to the registration result (ACT64)(ACT68).

[0096] Furthermore, when the input / output device 1523 receives an input operation (selection of a preset, coupon, or flyer item) while displaying screen 1002 (ACT69), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT70).

[0097] The communication interface 25 of the information processing server 20 receives requests corresponding to input operations. The processor 21 selects guidance information corresponding to the input operation. For example, it selects image information and voice information of a character corresponding to the input operation. The communication interface 25 transmits the image information and voice information of the character corresponding to the input operation to the buyer communication terminal 10 (ACT71).

[0098] The communication interface 14 of the buyer communication terminal 10 receives character image information and voice information corresponding to the input operation, and the input / output device 1523 transitions screen 1001 to screen 1004, as shown in Figure 18, and outputs character image information and voice information corresponding to the input operation (ACT72). By outputting character image information and voice information corresponding to the input operation or screen transition and providing various information, the input / output device 1523 can provide an enjoyable shopping experience.

[0099] • Character enlargement or reduction function (product registration screen) Figures 19 to 23 are examples of screens corresponding to the character enlargement or reduction function (product registration screen). The operation is as shown in the sequence diagram in Figure 15 and is omitted here. As shown in Figure 19, the input / output device 1523 displays a screen 1005 containing an image of a character of a first size. The input / output device 1523 moves the character image in response to the selection and movement operations of the character image of the first size (see Figure 19). The input / output device 1523 may also output the character's voice in response to the selection and movement operations of the character image of the first size.

[0100] Furthermore, the input / output device 1523 responds to selection operations such as erase marks displayed in response to the image of the first-size character (see screen 1006 in Figure 20) and erases the image of the first-size character (see screen 1007 in Figure 21). In response to erasing the image of the first-size character, the input / output device 1523 may display an image of a second-size character, smaller than the first size, in a predetermined position (outer frame). In addition, the input / output device 1523 may output the character's voice in response to erasing the image of the first-size character.

[0101] Furthermore, the input / output device 1523 may display a character image of the first size in response to a selection operation of a character image of the second size at a predetermined position (see screen 1008 in Figure 22) (see screen 1009 in Figure 23). In addition, the input / output device 1523 may output the character's voice in response to a selection operation of a character image of the second size at a predetermined position.

[0102] • Adult mode function Figure 24 is a sequence diagram showing an example of the adult mode function. Figure 25 shows an example of the screen before adult mode is activated. Figure 26 shows an example of the screen after adult mode is activated.

[0103] For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the output settings for the image and sound of a predetermined character, according to the output settings for the image and sound of a predetermined character received by the input / output device 552 (ACT81). The processor 21 of the information processing server 20 stores the output settings for the image and sound of a predetermined character in the main memory 22, etc. (ACT82).

[0104] When the processor 11 of the buyer communication terminal 10 completes the authentication process, the input / output device 1523 displays the screen 1001 shown in Figure 16. When the input / output device 1523 receives an input operation (selection to start shopping or character selection) via the screen 1001 (ACT83), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT84).

[0105] The communication interface 25 of the information processing server 20 receives requests corresponding to input operations. The processor 21 selects guidance information corresponding to the input operation. For example, it selects image information and voice information of a character corresponding to the input operation. The communication interface 25 transmits the image information and voice information of the character corresponding to the input operation to the buyer communication terminal 10 (ACT85).

[0106] The communication interface 14 of the buyer communication terminal 10 receives image and audio information of a character in response to an input operation, and the input / output device 1523 outputs image and audio information of a character in response to an input operation (ACT86).

[0107] For example, the input / output device 1523 displays screen 1010 as shown in Figure 25. Screen 1010 includes an item for specifying adult mode. When the input / output device 1523 receives an input operation in which the item for specifying adult mode is selected (ACT87), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT88).

[0108] The communication interface 25 of the information processing server 20 receives a request corresponding to the input operation. The processor 21 instructs the system to stop outputting the character's image information and audio information based on the request corresponding to the input operation. The communication interface 25 transmits the message to stop outputting the character's image information and audio information to the buyer communication terminal 10 (ACT89).

[0109] The communication interface 14 of the buyer communication terminal 10 receives a notification to stop outputting character image and sound information, and the input / output device 1523 transitions screen 1010 to screen 1011. Screen 1011 does not output character image and sound information (ACT90). Adults can concentrate on shopping without the output of character image and sound information.

[0110] Alternatively, an option to specify adult mode may be displayed on the screen, and while this option remains selected, the character's image and sound information may not be output. Or, an option to switch between adult mode and child mode may be displayed on the screen, and depending on the selection of this option, the system may switch between adult mode, which does not output character image information, and child mode, which does output character image information.

[0111] The self-checkout system 100's adult mode function temporarily disables the output of character images and sounds intended for children accompanied by their parents, thereby improving usability for parents.

[0112] • Item selection function using character image movement Figure 27 is a sequence diagram showing an example of an item selection function using character image movement. Figure 28 is a diagram showing an example of screen transitions using character image movement. Figure 29 is a diagram showing the relationship between each divided area and each item.

[0113] For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the output settings for the image and sound of a predetermined character, according to the output settings for the image and sound of a predetermined character received by the input / output device 552 (ACT101). The processor 21 of the information processing server 20 stores the output settings for the image and sound of the predetermined character in the main memory 22, etc. (ACT102).

[0114] When the processor 11 of the buyer communication terminal 10 completes the authentication process, the input / output device 1523 displays the screen 1001 shown in Figure 16. When the input / output device 1523 receives an input operation (selection to start shopping or character selection) via the screen 1001 (ACT 103), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT 104).

[0115] The communication interface 25 of the information processing server 20 receives a request corresponding to the input operation. The processor 21 selects guidance information corresponding to the input operation. For example, it selects character image information and voice information corresponding to the input operation. The communication interface 25 transmits the character image information and voice information corresponding to the input operation to the buyer communication terminal 10 (ACT105).

[0116] The communication interface 14 of the buyer communication terminal 10 receives image information and audio information of a character corresponding to the input operation, and the input / output device 1523 outputs image information and audio information of a character corresponding to the input operation (ACT106).

[0117] For example, the input / output device 1523 displays screen 1012 as shown in Figure 28. Screen 1012 includes an image of a character, and further includes multiple item images of the character. When the input / output device 1523 receives an input operation to move the character image to a predetermined area (the area of ​​a predetermined item) (ACT 107) (see screen 1013 in Figure 28), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT 108).

[0118] The communication interface 25 of the information processing server 20 receives requests corresponding to input operations. The processor 21 executes items assigned to predetermined areas. As shown in Figure 29, each item is assigned to each partitioned area. The communication interface 25 transmits predetermined item execution information corresponding to the execution of predetermined items assigned to predetermined areas to the buyer communication terminal 10 (ACT109).

[0119] The communication interface 14 of the buyer communication terminal 10 receives predetermined item execution information, and the input / output device 1523 transitions screen 1013 to screen 1014. Screen 1014 is an example of predetermined item execution information (ACT110). If there is no input operation for a certain period of time (e.g., 30 seconds), the input / output device 1523 transitions screen 1014 back to screen 1012. For example, even if a child accompanied by a parent moves the character image and transitions screen 1013 to screen 1014, screen 1014 will return to screen 1012 after a certain period of time, allowing the parent's shopping operation to proceed smoothly.

[0120] Screen 1012 contains item buttons corresponding to each item (presets, coupons, flyers, etc.). By selecting a designated item button, the designated function corresponding to that item button can be executed. This designated function can be executed by moving the character's image. In other words, by moving the character's image to a designated area, the designated function assigned to that area can be executed, making shopping more enjoyable.

[0121] • Output function for character voices, etc. (on the accounting screen) Figure 30 is a sequence diagram showing an example of the output function for character voices, etc. (accounting screen). Figures 31 and 32 are diagrams showing examples of the accounting screen. For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the output settings for the image and sound of a predetermined character, according to the output settings for the image and sound of a predetermined character received by the input / output device 552 (ACT111). The processor 21 of the information processing server 20 stores the output settings for the image and sound of the predetermined character in the main memory 22, etc. (ACT112).

[0122] When the processor 11 of the buyer communication terminal 10 completes the authentication process, the input / output device 1523 displays screen 1001 as shown in Figure 16 and transitions the screen according to the input operation. For example, in response to the input of the payment button, the input / output device 1523 transitions screen 1016 as shown in Figure 31 to screen 1017.

[0123] When the input / output device 1523 receives an input from the accounting button (ACT113), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT114).

[0124] The communication interface 25 of the information processing server 20 receives a request corresponding to an input operation. The processor 21 selects guidance information corresponding to the input operation. For example, it selects accounting guidance corresponding to the input operation. The communication interface 25 sends the accounting guidance corresponding to the input operation to the buyer communication terminal 10 (ACT115).

[0125] The communication interface 14 of the buyer communication terminal 10 receives accounting guidance in response to input operations, and the input / output device 1523 outputs accounting guidance in response to input operations (ACT 116). The accounting guidance includes character image information and voice information. The input / output device 1523 displays a screen 1017 containing character image information and outputs character voice information. For example, the input / output device 1523 uses the character's voice information to provide various information to confirm whether or not a shopping bag is needed.

[0126] Furthermore, when the input / output device 1523 receives an input from the accounting button (ACT113), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT114).

[0127] The communication interface 25 of the information processing server 20 receives a request corresponding to an input operation. The processor 21 selects guidance information corresponding to the input operation. For example, it selects accounting guidance corresponding to the input operation. The communication interface 25 sends the accounting guidance corresponding to the input operation to the buyer communication terminal 10 (ACT115).

[0128] The communication interface 14 of the buyer communication terminal 10 receives accounting guidance in response to input operations, and the input / output device 1523 outputs accounting guidance in response to input operations (ACT 116). The accounting guidance includes character image information and voice information. The input / output device 1523 displays a screen 1017 containing character image information and outputs character voice information. For example, the input / output device 1523 uses the character's voice information to provide various information to confirm whether or not a shopping bag is needed.

[0129] For example, the input / output device 1523 displays screen 1018 shown in Figure 32 in response to the input of whether or not a shopping bag needs to be purchased. The input / output device 1523 also transitions screen 1018 shown in Figure 32 to screen 1019 in response to the input of an operation for accounting processing (reading of the accounting barcode).

[0130] When the input / output device 1523 receives an input for accounting operations (ACT121), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT122).

[0131] The communication interface 25 of the information processing server 20 receives a request corresponding to the input operation. The processor 21 selects guidance information corresponding to the input operation. For example, it selects a payment completion notification corresponding to the input operation. The communication interface 25 sends the payment completion notification corresponding to the input operation to the buyer communication terminal 10 (ACT123).

[0132] The communication interface 14 of the buyer communication terminal 10 receives an accounting completion notification corresponding to the input operation, and the input / output device 1523 outputs an accounting completion notification corresponding to the input operation (ACT124).

[0133] Furthermore, the information processing server 20 may generate accounting guidance based on the product identification information read by the first scanner 1521 and the product identification information read by the second scanner 1522.

[0134] For example, the buyer communication terminal 10 transmits the product identification information read by the first scanner 1521 to the information processing server 20. The processor 21 of the information processing server 20 functions as a first generation unit, which generates first guidance information including the product registration result based on the product identification information read by the first scanner. The information processing server 20 transmits the first guidance information to the buyer communication terminal 10. The buyer communication terminal 10 outputs the first guidance information.

[0135] Furthermore, the buyer communication terminal 10 transmits the product identification information read by the second scanner 1522 to the information processing server 20. The processor 21 of the information processing server 20 functions as a first generation unit, and the first generation unit generates second guidance information, including the product registration result, based on the product identification information read by the second scanner 1522. The information processing server 20 transmits the second guidance information to the buyer communication terminal 10. The buyer communication terminal 10 outputs the second guidance information.

[0136] Furthermore, the processor 21 of the information processing server 20 functions as a second generation unit, which generates accounting guidance based on the product identification information read by the first scanner 1521 and the product identification information read by the second scanner 1522. The information processing server 20 transmits the accounting guidance to the buyer communication terminal 10. The buyer communication terminal 10 outputs the accounting guidance.

[0137] With the above configuration, the information processing server 20 displays product registration screens corresponding to the first scanner 1521 and the second scanner 1522 on the buyer communication terminal 10, and can settle the accounting for products corresponding to the product identification information read from the first scanner 1521 and the second scanner 1522 (both scanners) in one go. For example, when a parent and child are shopping together, the parent can use the first scanner 1521 to proceed with shopping while the child uses the second scanner 1522 to help with shopping. Note that there may be two or more scanners.

[0138] [Support Functions] The self-checkout system 100 is equipped with support functions. For example, the buyer communication terminal 10 can provide a comfortable shopping experience by outputting support information in a timely manner according to the selected mode or the mode pre-set by the staff communication terminal 50. The support functions are described below. Requests and other information transmitted from the buyer communication terminal 10 include the terminal identification information of the buyer communication terminal 10. The information processing server 20 identifies the communication partner's terminal from the terminal identification information included in the requests and other information transmitted from the buyer communication terminal 10 and provides product registration screens according to multiple modes.

[0139] • Mode selection Figure 33 is a sequence diagram showing an example of mode selection. Figure 34 is an example of a screen (top screen) that includes multiple mode selection buttons. Figure 35 is an example of a screen (product registration screen) that is displayed in response to the selection of a predetermined mode. When the processor 11 of the buyer communication terminal 10 completes the authentication process, the input / output device 1523 displays the screen 1020 shown in Figure 34 and transitions the screen according to the input operation. The screen 1020 includes first, second, and third mode selection buttons. The first mode selection button selects a first mode that provides support for customers with children. The second mode selection button selects a second mode that provides support for standard customers. The third mode selection button selects a third mode that provides support for customers who are not proficient in operation input.

[0140] When the input / output device 1523 receives input from any one of the first, second, or third mode selection buttons (ACT131), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT132).

[0141] The communication interface 25 of the information processing server 20 receives a request corresponding to an input operation. The processor 21 holds the request corresponding to the input operation (ACT 133) and selects a mode corresponding to the input operation. The processor 21 executes the first mode in response to the input operation of the first mode selection button, the second mode in response to the input operation of the second mode selection button, and the third mode in response to the input operation of the third mode selection button. The processor 21 selects a guidance corresponding to the execution mode. The communication interface 25 sends the guidance corresponding to the execution mode to the buyer communication terminal 10 (ACT 134).

[0142] The communication interface 14 of the buyer communication terminal 10 receives guidance corresponding to the execution mode, and the input / output device 1523 outputs guidance corresponding to the execution mode on the screen 1020 (ACT135).

[0143] When the input / output device 1523 receives an input operation (selection to start shopping) via the screen 1020 (ACT 136), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT 137).

[0144] The communication interface 25 of the information processing server 20 receives requests corresponding to input operations. The processor 21 selects the execution mode and the product registration screen corresponding to the input operation. The communication interface 25 transmits the execution mode and the product registration screen corresponding to the input operation to the buyer communication terminal 10 (ACT138).

[0145] The communication interface 14 of the buyer communication terminal 10 receives a product registration screen corresponding to the execution mode and input operation, and the input / output device 1523 outputs a product registration screen corresponding to the execution mode and input operation (ACT 139). For example, the input / output device 1523 displays the screen 1021 shown in Figure 35 in response to the execution of the first mode or the third mode and the input operation. The screen 1021 displayed in response to the execution of the first mode or the third mode shows product registration information using enlarged size (second size) characters and symbols, etc. Note that the screen 1003 shown in Figure 17, displayed in response to the execution of the second mode, shows product registration information using standard size (first size) characters and symbols, etc.

[0146] • Support functions for customers who have difficulty with operation input. Referring to Figures 12 and 13, the functions of the buyer communication terminal 10 and the information processing server 20 for providing support functions for customers who are not proficient in operation input will be explained.

[0147] First, let's explain the operation of the buyer communication terminal 10. When the first scanner 1521 reads product identification information such as a product code, the first device interface 1511 outputs read information including the first interface information and the product identification information. Also, when the second scanner 1522 reads product identification information such as a product code, the second device interface 1512 outputs read information including the second interface information and the product identification information.

[0148] The detection unit 111 of the processor 11 detects product identification information in response to the reading of product identification information by the first scanner 1521 or the second scanner 1522. The first output unit 112 outputs a product registration request including the product identification information to the information processing server 20. The communication interface 14 transmits the product registration request to the information processing server 20.

[0149] Next, the operation of the information processing server 20 will be explained. The communication interface 25 receives a product registration request. The acquisition unit 211 of the processor 21 acquires the reception interval of the product identification information read by the first scanner 1521 or the second scanner 1522 of the buyer communication terminal 10.

[0150] The determination unit 212 determines whether assistance is needed based on the acquired reception interval. The determination unit 212 determines that assistance is needed if the reception interval exceeds a standard time based on the assistance request mode specified in the buyer communication terminal 10. For example, the auxiliary storage device 23 stores the standard time. The standard time is a time that can be set arbitrarily, for example, between 30 seconds and 600 seconds. The assistance request mode is either a first mode that provides assistance for customers with children, or a third mode that provides assistance for customers who have difficulty with operation input. In other words, the determination unit 212 determines that assistance is needed if either the first mode or the third mode is specified and the reception interval exceeds the standard time.

[0151] The output unit 213 outputs first support information to the buyer communication terminal 10 based on the determination result that support is needed. The communication interface 25 transmits the first support information to the buyer communication terminal 10.

[0152] Let's explain the operation of the buyer communication terminal 10 again. The communication interface 14 receives first support information transmitted from the information processing server 20. The acquisition unit 113 of the processor 11 acquires the first support information. For example, the acquisition unit 113 acquires first support information that includes guidance to be notified via a pop-up.

[0153] The second output unit 114 of the processor 11 outputs first support information, including guidance to be notified via pop-up, to the touch panel display 15231. The touch panel display 15231 displays the first support information, including guidance to be notified via pop-up.

[0154] Figure 36 is a sequence diagram showing an example of a support function for customers who have difficulty with operation input. Figure 37 is an example of a screen that includes support information for customers who have difficulty with operation input.

[0155] For example, the processor 51 of the staff communication terminal 50 instructs the information processing server 20 to set the reference time according to the reference time setting received by the input / output device 552 (ACT141). The processor 21 of the information processing server 20 stores the reference time in the main memory 22, etc. (ACT142).

[0156] When the processor 11 of the buyer communication terminal 10 completes the authentication process, the input / output device 1523 displays the screen 1020 shown in Figure 34. When the input / output device 1523 receives input from any one of the first, second, or third mode selection buttons via the screen 1020, the processor 11 executes the mode corresponding to the received input. Here, we will describe the case in which the first mode, which provides support for customers with children, or the third mode, which provides support for customers who have difficulty with inputting commands, is executed.

[0157] When the input / output device 1523 receives an input operation (selection to start shopping) via the screen 1020 (ACT143), the communication interface 14 sends a request corresponding to the input operation to the information processing server 20 (ACT144).

[0158] The communication interface 25 of the information processing server 20 receives requests corresponding to input operations. The processor 21 selects the execution mode and the product registration screen corresponding to the input operation. The communication interface 25 transmits the execution mode and the product registration screen corresponding to the input operation to the buyer communication terminal 10 (ACT145).

[0159] The communication interface 14 of the buyer communication terminal 10 receives a product registration screen corresponding to the execution mode and input operation, and the input / output device 1523 outputs a product registration screen corresponding to the execution mode and input operation (ACT146). For example, the input / output device 1523 displays the screen 1021 shown in Figure 35 according to the execution of the first mode or the third mode and the input operation.

[0160] Furthermore, when the input / output device 1523 is displaying screen 1021 and the first scanner 1521 or the second scanner 1522 reads product identification information (ACT 147), the communication interface 14 sends a product registration request including the read product identification information to the information processing server 20 (ACT 148).

[0161] The communication interface 25 of the information processing server 20 receives a product registration request. The processor 21 registers the product identification information included in the product registration request and selects guidance information according to the registration result. The communication interface 25 transmits the guidance information according to the registration result to the buyer communication terminal 10 (ACT 149). The acquisition unit 211 of the processor 21 acquires the reception time (time information indicating the reception timing) of the product identification information included in the product registration request and stores the first reception time (ACT 150).

[0162] When the first scanner 1521 or the second scanner 1522 reads the product identification information again (ACT 151), the communication interface 14 sends a product registration request containing the read product identification information to the information processing server 20 (ACT 152).

[0163] The communication interface 25 of the information processing server 20 receives a product registration request. The processor 21 registers the product identification information included in the product registration request and selects guidance information according to the registration result. The communication interface 25 transmits the guidance information according to the registration result to the buyer communication terminal 10 (ACT 153). The acquisition unit 211 of the processor 21 acquires the reception time (time information indicating the reception timing) of the product identification information included in the product registration request and stores a second reception time (ACT 154).

[0164] The determination unit 212 detects the reception interval from the difference between the first reception time and the second reception time, and determines whether support is needed based on the reception interval (ACT155). The determination unit 212 determines that support is needed if the difference time exceeds the reference time.

[0165] The output unit 213 outputs first support information to the buyer communication terminal 10 based on the determination result that support is needed. The communication interface 25 transmits the first support information to the buyer communication terminal 10 (ACT 156).

[0166] The communication interface 14 of the buyer communication terminal 10 receives first support information transmitted from the information processing server 20. The acquisition unit 113 of the processor 11 acquires the first support information. For example, the acquisition unit 113 acquires first support information that includes guidance to be notified via a pop-up.

[0167] The second output unit 114 of the processor 11 outputs first support information, including guidance to be notified via a pop-up, to the touch panel display 15231 (ACT 157). As shown in Figure 37, the touch panel display 15231 displays the first support information 1022, including guidance to be notified via a pop-up.

[0168] When the first or third mode is running, the touch panel display 15231 outputs first support information to assist the user if the interval between the scanner's product identification information reading operations exceeds a standard time. This allows for timely support for customers who are not proficient in manual operation, enabling them to shop comfortably and potentially increasing the number of items purchased.

[0169] • Support functions for customers who are not proficient in using the system and for staff members assisting them. The support functions for customers who have difficulty with operation input were explained with reference to Figures 36 and 37. Here, we will explain the support functions for customers who have difficulty with operation input and the staff who are assisting them. As the support functions for customers who have difficulty with operation input have already been explained, a detailed explanation will be omitted.

[0170] Figure 38 is a sequence diagram showing an example of support functions for customers who have difficulty with operation input and for staff assisting them. Figure 39 is an example of a screen containing support information for staff assisting them.

[0171] Acts 141 through 157 are as described above.

[0172] The output unit 213 outputs second support information to the staff communication terminal 50 based on the determination result indicating that support is needed. The communication interface 25 transmits the second support information to the staff communication terminal 50 (ACT158). For example, the second support information includes terminal identification information that identifies the buyer communication terminal 10 that sent the product registration request in ACT148 and ACT152.

[0173] The communication interface 54 of the staff communication terminal 50 receives second support information transmitted from the information processing server 20. The processor 51 acquires the second support information. For example, the processor 51 acquires second support information that includes instructions to be notified via a pop-up.

[0174] The processor 51 outputs second support information, including instructions to be notified via a pop-up, to the touch panel display 5521 (ACT159). As shown in Figure 39, the touch panel display 5521 displays the second support information 5001, including instructions to be notified via a pop-up.

[0175] The touch panel display 5521 outputs second support information to assist operation when the interval between the scanner's reading of product identification information exceeds a standard time, while the first or third mode is being executed on the buyer communication terminal 10. The second support information also includes terminal identification information that identifies the buyer communication terminal 10 that sent the product registration request in ACT148 and ACT152. This allows for timely support for customers who are not proficient in operation input, enabling them to shop comfortably and potentially increasing the number of items purchased.

[0176] The above description shows an example where the buyer communication terminal 10 selects a mode, but the mode may be pre-set. Specifically, the staff communication terminal 50 can also set the mode for each buyer communication terminal 10. For example, the processor 51 and input / output device 552 of the staff communication terminal 50 function as a setting unit that sets the mode in response to staff operations, and a display unit that displays the product registration status registered by the staff communication terminal 50. The staff communication terminal 50 sets the mode for each buyer communication terminal 10 in response to staff operations and sends the setting to the transaction processing server 20. The transaction processing server 20 receives and stores the mode for each buyer communication terminal 10. When the buyer communication terminal 10 accepts an input operation (selection to start shopping) in response to a request sent from the buyer communication terminal 10, the transaction processing server 20 sends a request corresponding to the input operation to the information processing server 20. The information processing server 20 sends a product registration screen corresponding to the mode setting of the buyer communication terminal 10 to the buyer communication terminal 10.

[0177] As described above, the information processing server 20 provides product registration screens corresponding to multiple modes, and the buyer communication terminal 10 displays the provided product registration screens. Specifically, the buyer communication terminal 10 can set the mode. For example, the processor 11 and input / output device 1523 of the buyer communication terminal 10 function as a setting unit that sets the mode in response to buyer operations, and a display unit that displays the product registration status registered by the buyer communication terminal 10.
