(Embodiment 1)
(1) Overview A store support system 10 (see FIG. 1) according to this embodiment is a system that supports work at a store 9 (see FIG. 1) by scheduling work at the store 9. In this embodiment, a case will be described as an example in which the store support system 10 is installed at a store 9 that is a retail store such as a convenience store, supermarket, department store, drug store, home appliance retailer, or home improvement center.

In this disclosure, the work in the store 9 is also referred to as a task. In this disclosure, a "task" is work that occurs in the store 9, in other words, work that is assigned to workers 91A, 91B, and 91C (see FIG. 1) in the store 9 as work and is performed by the workers 91A, 91B, and 91C. In other words, the workers 91A, 91B, and 91C who perform the work (tasks) managed by the store support system 10 are clerks working in the store 9. In this disclosure, when there is no particular distinction between the multiple workers 91A, 91B, and 91C, each of the multiple workers 91A, 91B, and 91C may be referred to as a "worker 91."

Here, not only work performed inside the store 9, but also work performed outside the store 9, such as cleaning the roads around the store 9, are included in the tasks. In addition, as will be described in detail later, the tasks include two types of tasks: "periodic tasks" that occur periodically, and "irregular tasks" that occur irregularly. For example, if the store 9 is a convenience store, examples of periodic tasks include displaying products, taking inventory, and cleaning toilets. Examples of irregular tasks include cashiering, serving fast food (FF), refilling hot water in an electric kettle, refilling fast food (prepared food), changing garbage bags, stocking products, and stocking consumables. "Fast food" here refers to light meals cooked in the store 9, and is also called hot snacks or hot food. However, among the irregular tasks, tasks that may occur periodically, such as refilling hot water in an electric kettle, refilling fast food (prepared food), changing garbage bags, stocking products, and stocking consumables, are also called "semi-periodic tasks".

The store support system 10 according to this embodiment generates work schedule information and outputs the generated work schedule information. In this disclosure, "work schedule information" refers to information that represents the correspondence between tasks and the timing of instructions for the tasks, and specifies the schedule for executing the tasks in the store 9. In this disclosure, "instruction timing" refers to the timing of instructions to execute a task, i.e., the timing when the worker 91 should execute the task.

That is, among tasks, tasks with fixed instruction timings, such as regular tasks and semi-regular tasks, are included in the work schedule information, and the correspondence with the instruction timings is specified in the work schedule information. In this way, a task with the instruction timings specified in the work schedule information is also called a "first task". On the other hand, tasks without fixed instruction timings, such as non-regular tasks other than semi-regular tasks, are not included in the work schedule information. In this way, a task that is not included in the work schedule information, that is, a task with no instruction timings specified in the work schedule information, is also called a "second task". In other words, the work schedule information represents the correspondence between the first task among tasks and the instruction timings of the first task, and the second task is a task different from the first task. Examples of the first task include displaying products, taking inventory, cleaning the toilet, refilling hot water in an electric kettle, refilling fast food (prepared food), changing garbage bags, putting out products, refilling consumables, etc., which are regular or semi-regular tasks. Examples of the second task include working at the cash register and working at fast food, which are non-regular tasks other than semi-regular tasks.

Examples of the manner in which work schedule information may be output include transmission to an information terminal, display, audio output, recording (writing) to a non-temporary recording medium, and printing (printing out). As will be described in more detail below, in this embodiment, as shown in FIG. 1, the store support system 10 comprises a server device 1, a management device 2 installed in a store 9, and worker terminals 3A, 3B, and 3C carried by workers 91. In this disclosure, when no particular distinction is made between the multiple worker terminals 3A, 3B, and 3C, each of the multiple worker terminals 3A, 3B, and 3C may be referred to as a "worker terminal 3."

The work schedule information is generated by the server device 1 and transmitted from the server device 1 to the management device 2. At this time, the work schedule information is transmitted from the server device 1 to the management device 2, and the work schedule information is output in the server device 1. The management device 2 transmits work instructions to the worker terminal 3 in accordance with the work schedule information, thereby notifying the worker 91 of the task (first task) and instructing the worker to execute the task.

Here, the store support system 10 may instruct the worker 91 to execute the task at the instruction timing, or may instruct the worker 91 to execute the task by notifying the worker 91 of the task together with the instruction timing at a time point prior to the instruction timing. In the former case, the store support system 10 instructs the worker 91 to execute the task in real time, so that the worker 91 executes the task immediately upon receiving the task notification. In the latter case, the store support system 10 instructs the worker 91 to execute the task by reservation, so that the worker 91 does not execute the task immediately upon receiving the task notification, but executes the task at the instruction timing notified together with the task. Furthermore, as a specific example of the latter case, the instruction timing notified together with the task may be the time at which the task should be executed, or may be the waiting time until the time at which the task should be executed. In other words, the "instruction timing" in the present disclosure may be any timing that is recognized by the worker 91 as the timing at which the task should be executed, and is not limited to the timing at which the store support system 10 notifies the worker 91 of the task.

The store support system 10 according to the present embodiment generates work schedule information based on task information related to the task (first task) and store information related to the status of the store 9. The "store status" in the present disclosure includes both the current status of the store 9 and the future status of the store 9 estimated from past performance, etc. For example, if the store 9 is a convenience store, examples of the status of the store 9 include the number of customers, sales, product inventory status, and the work schedule (work shift) of the worker 91 (clerk) at the store 9. The current status of the number of customers and sales can be identified, for example, from the detection results of various sensors (including cameras) installed in the store 9, and information from the store computer 6 described below or a separate POS (Point Of Sales) system. In addition, the future status of the number of customers and sales can be estimated, for example, from the reservation status, the weather (including forecasts) around the store 9, and the presence or absence and time of events (sports matches, concerts, etc.) held around the store 9.

That is, the store support system 10 according to this embodiment uses at least task information and store information when generating work schedule information that indicates the correspondence between a task (first task) and the timing of instruction for the task. As a result, if the situation at the store 9 changes, the work schedule information will also change in accordance with the situation at the store 9, making it possible to issue appropriate work instructions that match the situation at the store 9. Therefore, even if there is a sudden change in the situation at the store 9, such as the arrival of a group of customers or the absence of a worker 91, the store support system 10 can issue appropriate work instructions that match the situation at the store 9.

In this way, the store support system 10 according to this embodiment generates and outputs work schedule information that indicates the correspondence between tasks (first tasks) and the timing of instructions for the tasks, thereby scheduling work in the store 9 and supporting work in the store 9. Moreover, in this store support system 10, at least task information and store information are used when generating work schedule information. As a result, the store support system 10 is able to issue more appropriate work instructions compared to a configuration in which work schedule information is generated without considering the situation in the store 9. Furthermore, the store support system 10 is able to issue stable and reliable instructions for work, since it is not affected by the variation in the experience level of the manager, compared to when a manager such as a store manager issues work instructions.

The screen display method according to this embodiment is used, as an example, in the above-mentioned store support system 10, and is a method for displaying a work instruction screen D1 (see FIG. 4) on the worker terminal 3. The work instruction screen D1 is a screen for instructing the worker 91 to perform work. In this disclosure, the "screen" of the work instruction screen D1 or the like is an image (including text, graphs, icons, etc.) displayed on the display unit 32 (see FIG. 4) of the worker terminal 3 or the like. In other words, according to the screen display method according to this embodiment, the work instruction screen D1 for instructing the worker 91 to perform work is displayed on the worker terminal 3. Therefore, the worker 91 can check the work instructions by looking at the work instruction screen D1 displayed on the worker terminal 3.

Here, the screen display method according to this embodiment is used on a graphical user interface (GUI) of a computer system. In other words, the screen display method is a method of displaying a work instruction screen D1 on a worker terminal 3 that is mainly configured as a computer system.

This screen display method includes an acquisition process and a display process. The acquisition process is a process of acquiring acquired information. The acquired information is information about the work schedule information that represents the correspondence between the first task, which is the work of the worker 91, and the instruction timing of the first task. The display process is a process of displaying the work instruction screen D1 on the worker terminal 3 based on the acquired information acquired in the acquisition process. The work instruction screen D1 is a screen for instructing the worker 91 to perform work. Here, the work instruction screen D1 includes a first region R1 (see FIG. 4) and a second region R2 (see FIG. 4). The first region R1 is an area that displays a first object I1 (see FIG. 4) corresponding to the first task included in the work schedule information. The second region R2 is an area that displays a second object I2 (see FIG. 4) corresponding to the second task. The second task is the work of the worker 91 and is a task different from the first task.

According to this screen display method, the first task included in the work schedule information and the second task, which is the work of the worker 91 and is different from the first task, can be displayed in a listable form on the work instruction screen D1. Therefore, for example, a task such as cash register operation that is not included in the work schedule information, i.e., not associated with the instruction timing, can be instructed to the worker 91 on the work instruction screen D1 together with the first task by making it the second task. Therefore, the worker 91 can easily recognize the second task that is not included in the work schedule information as a task that he or she should perform in parallel with the first task that is included in the work schedule information. As a result, the screen display method makes it easier for the worker 91 to perform both the tasks included in the work schedule information and the tasks not included in the work schedule information, and it is possible to give more appropriate work instructions.

The store support system 10 according to the present embodiment also includes an instruction unit 24 (see FIG. 2), a detection unit 27 (see FIG. 2), and a performance output unit 18 (see FIG. 2). The instruction unit 24 instructs each of the multiple workers 91 to perform at least one of a regular task and an irregular task for a number of tasks that are work performed by the multiple workers 91 in the store 9. The regular task is generated based on work schedule information. The work schedule information is information that represents the correspondence between each of the multiple tasks and the instruction timing. The irregular task occurs irregularly. The detection unit 27 detects the execution of at least one of the multiple tasks by a worker 91 instructed by the instruction unit 24 among the multiple workers 91. The performance output unit 18 generates performance information that represents the execution status of the task by each worker 91, and outputs the performance information. Here, the performance output unit 18 generates the performance information based on the detection result of the detection unit 27.

Here, the worker 91 who is the target of detection of execution of a certain task by the detection unit 27 is the worker 91 instructed by the instruction unit 24 among the multiple workers 91, that is, the worker 91 to whom this task is instructed by the instruction unit 24. Also, the manner in which the performance information is output by the performance output unit 18 includes, for example, transmission to an information terminal, display, audio output, recording (writing) to a non-temporary recording medium, and printing (printing out), etc. In this embodiment, as an example, the performance output unit 18 outputs the performance information to the log recording unit 15 (see FIG. 2 ) to record the performance information in the log recording unit 15.

With this configuration, the store support system 10 can detect the execution of a task by a worker 91 who has been instructed to perform the task using the detection unit 27, and automatically generate and output performance information indicating the execution status of the task by each worker 91 based on the detection result. This makes it possible for the worker 91 to leave a record of work results when starting or completing a task without recording the performance information. As a result, there is an advantage in that a decrease in work efficiency due to leaving a record of work results is unlikely to occur.

(2) Details The store support system 10 according to this embodiment will be described in detail below. In this embodiment, a convenience store will be described as an example of the store 9 in which the store support system 10 is introduced. In other words, the workers 91 who execute the work (tasks) managed by the store support system 10 are convenience store clerks (including part-time workers and part-timers). The server device 1 can be connected to management devices 2 and the like installed in multiple stores 9 via a network 4, which allows the store support system 10 to target multiple stores 9 for support. However, in this embodiment, a case will be described in which the target of support by the store support system 10 is one store 9.

(2.1) Overall Configuration Here, the overall configuration of the store support system 10 according to the present embodiment will be described. As shown in FIG. 1 and FIG. 2, the store support system 10 includes a server device 1, a management device 2 installed in the store 9, and an operator terminal 3 carried by an operator 91, as described above. As shown in FIG. 1 and FIG. 2, the store support system 10 according to the present embodiment further includes a store computer 6, a plurality of sensors 7A, 7B, 7C, an administrator terminal 8, a detection unit 27, and an occurrence detection unit 28. However, at least a part of the store computer 6, the plurality of sensors 7A, 7B, 7C, and the administrator terminal 8 may not be included as components of the store support system 10. In the present disclosure, when the plurality of sensors 7A, 7B, 7C are not particularly distinguished from each other, each of the plurality of sensors 7A, 7B, 7C may be referred to as a "sensor 7".

The server device 1 mainly comprises a computer system having one or more processors and memory. The server device 1 is connected to a network 4 such as the Internet. The server device 1 is installed, for example, in a service company that provides the store support system 10, or in an operating company of the store 9. It is preferable that the server device 1 uses a Paas (Platform as a Service) environment, which is a public cloud environment without management of the OS, runtime, and middleware.

2, the server device 1 has a first communication unit 11, an acquisition unit 12, a schedule generation unit 13, an output unit 14, a log recording unit 15, a task generation unit 16, an allocation unit 17, and a performance output unit 18. In the server device 1, one or more processors execute a program recorded in memory, thereby functioning as at least the acquisition unit 12, the schedule generation unit 13, the output unit 14, the task generation unit 16, the allocation unit 17, and the performance output unit 18. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-temporary recording medium such as a memory card and provided.

The first communication unit 11 is, for example, a communication module that communicates bidirectionally between the management device 2 and the worker terminal 3, etc. The first communication unit 11 is connected to the network 4 and communicates with the management device 2 and the worker terminal 3, etc. via the network 4.

The acquisition unit 12 is connected to the first communication unit 11, and acquires various information (data) from, for example, the management device 2, etc., via the first communication unit 11. In this embodiment, the acquisition unit 12 acquires, from the management device 2, etc., information relating to the status of the store 9, such as task information and store information used to generate work schedule information.

The schedule generation unit 13 generates work schedule information. In this embodiment, the schedule generation unit 13 generates work schedule information based on at least the task information and store information acquired by the acquisition unit 12. The work schedule information is information that represents, for at least a plurality of tasks, the correspondence between each of the plurality of tasks and the instruction timing.

The output unit 14 outputs the work schedule information generated by the schedule generation unit 13. In this embodiment, the output unit 14 outputs the work schedule information by causing the first communication unit 11 to transmit the work schedule information to the management device 2.

The log recording unit 15 is a non-transitory recording medium that stores performance information. In this disclosure, "performance information" is information that represents the execution status of tasks by each worker 91. Specifically, performance information is a log related to completed tasks, and includes, for example, the task name, the time the task was completed, and information about the worker 91 who performed the task.

The performance output unit 18 generates performance information that indicates the execution status of tasks by each worker 91, and outputs the performance information. Here, the performance output unit 18 generates the performance information based on the detection result of the detection unit 27. As described above, in this embodiment, the performance output unit 18 records the performance information in the log recording unit 15 by outputting the performance information to the log recording unit 15. In other words, the performance output unit 18 outputs the performance information by recording (writing) the performance information in the log recording unit 15.

There are roughly two ways in which the performance output unit 18 generates performance information. In the first way, the performance output unit 18 generates performance information based on a completion notification received by the first communication unit 11 from the worker terminal 3, and outputs the performance information (records it in the log recording unit 15). In this embodiment, it is assumed that the completion notification is indirectly transmitted from the worker terminal 3 to the server device 1 via the management device 2, but the completion notification may also be transmitted directly from the worker terminal 3 to the server device 1.

In a second aspect, the performance output unit 18 generates performance information based on the detection result of the detection unit 27 described below, and outputs the performance information. The detection unit 27 detects the execution of at least one of the multiple tasks by one of the multiple workers 91 who has been assigned by the assignment unit 17. Therefore, in this aspect, when the detection unit 27 detects the execution of a task by the worker 91, the performance output unit 18 can automatically generate performance information based on the detection result of the detection unit 27, and output the performance information.

In addition, in the second aspect, that is, when the performance output unit 18 generates performance information based on the detection result of the detection unit 27, it is sufficient that the performance information is generated based on at least the detection result of the detection unit 27, and information other than the detection result of the detection unit 27 may be taken into account as described below.

That is, the performance output unit 18 generates performance information based on the work schedule information in addition to the detection results of the detection unit 27. That is, when the performance output unit 18 generates performance information, not only the detection results of the detection unit 27 but also the work schedule information (the correspondence between tasks and instruction timing) is used.

Furthermore, the performance output unit 18 generates performance information based on the worker information in addition to the detection results of the detection unit 27. "Worker information" in this disclosure is information about multiple workers 91. The worker information includes, for example, the names and skills of the workers 91. In other words, when generating performance information in the performance output unit 18, not only the detection results of the detection unit 27 but also the worker information (skills of the workers 91, etc.) are used.

Furthermore, the performance output unit 18 generates performance information based on the work status of each of the multiple workers 91, in addition to the detection results of the detection unit 27. The "work status" in this disclosure is information related to the current task execution status of each worker 91. The work status includes, for example, whether or not each worker 91 is currently performing a task. In other words, when generating performance information in the performance output unit 18, not only the detection results of the detection unit 27 but also the work status of each worker 91 (whether or not a task is being performed, etc.) is used.

In this way, in the second mode, that is, when generating performance information based on the detection results of the detection unit 27, the performance output unit 18 generates performance information using not only the detection results of the detection unit 27, but also work schedule information, worker information, and the work status of each worker 91.

The task generation unit 16 generates task information related to irregular tasks (hereinafter also referred to as "irregular task information"). In this embodiment, the task generation unit 16 generates the irregular task information based on at least the store information acquired by the acquisition unit 12. As described above, irregular tasks include semi-regular tasks that may occur periodically, such as refilling hot water in an electric kettle, changing garbage bags, putting out products, and replenishing consumables, as well as second tasks other than semi-regular tasks, such as working the cash register and serving fast food.

The allocation unit 17 allocates the multiple tasks in the work schedule information to the multiple workers 91 based on the worker information. As will be explained in detail in the section "(2.2.3) Allocation unit," the allocation unit 17 notifies each of the multiple workers 91 of the multiple tasks, and allocates the tasks to a worker 91 among the multiple workers 91 who accepts the notification.

The operations of the acquisition unit 12, schedule generation unit 13, output unit 14, log recording unit 15, task generation unit 16, allocation unit 17 and performance output unit 18 will be explained in further detail in section "(2.2) Operation".

The management device 2 is installed in the store 9. The management device 2 is mainly composed of a computer system having one or more processors and memories. The management device 2 is connected to the network 4 via a router 5 installed in the store 9.

As shown in Fig. 2, the management device 2 has a second communication unit 21, a processing unit 22, an interface 23, an instruction unit 24, and a memory unit 25. In the management device 2, one or more processors execute a program recorded in memory, thereby functioning as at least the processing unit 22 and the instruction unit 24. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-temporary recording medium such as a memory card and provided.

The second communication unit 21 is, for example, a communication module that communicates bidirectionally between the server device 1 and the worker terminal 3, etc. The second communication unit 21 is connected to the network 4 and communicates with the server device 1 via the network 4. The second communication unit 21 also communicates with the worker terminal 3 by wireless communication using radio waves as a medium, such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

The processing unit 22 is connected to the second communication unit 21, and transmits and receives various information (data) between, for example, the server device 1 and the like, via the second communication unit 21. The processing unit 22 is also connected to the monitor 26, and controls the monitor 26 so that various information is displayed on the monitor 26.

The interface 23 is connected to a plurality of sensors 7A, 7B, 7C, a detection unit 27, and an occurrence detection unit 28, and acquires the detection results of each sensor 7, detection unit 27, and occurrence detection unit 28. The connection (communication) method between the interface 23 and the sensor 7, detection unit 27, and occurrence detection unit 28 may be a wired method or a wireless method. In this embodiment, as shown in FIG. 1, three sensors 7A, 7B, and 7C are connected to the interface 23. However, the number of sensors 7 connected to the interface 23 is not limited to three, and may be one, two, or four or more. Similarly, one each of the detection unit 27 and the occurrence detection unit 28 is connected to the interface 23, but the number of each of the detection unit 27 and the occurrence detection unit 28 connected to the interface 23 is not limited to one, and may be two or more.

The instruction unit 24 instructs each worker 91 on at least one of the multiple tasks, a periodic task, and an irregular task that occurs irregularly. The periodic task is generated based on work schedule information. The work schedule information is information that represents the correspondence between each of the multiple tasks and the instruction timing.

Here, the instruction unit 24 generates and outputs a work instruction, and instructs each worker 91 to perform a task by the work instruction. In this embodiment, the instruction unit 24 generates a work instruction according to the work schedule information received from the server device 1. The work instruction generated according to the work schedule information is a work instruction for a first task that is a periodic task or a semi-periodic task. Furthermore, in this embodiment, the instruction unit 24 generates a work instruction according to a work order received from the server device 1. The work instruction generated according to the work order is a work instruction for a second task that is a task other than a semi-periodic task among non-periodic tasks. Therefore, the instruction unit 24 generates a work instruction that instructs the execution of both the first task and the second task. The instruction unit 24 outputs the work instruction by transmitting the generated work instruction from the second communication unit 21 to the worker terminal 3. The "work instruction" in this disclosure is data for instructing the worker 91 to perform a task, and includes at least information for identifying the task.

The memory unit 25 is a non-transitory recording medium. The memory unit 25 stores the work schedule information received from the server device 1, and the detection results obtained by the interface 23 from the sensor 7, the detection unit 27, and the occurrence detection unit 28.

The worker terminal 3 is carried by a worker 91 (a store clerk) at the store 9. The worker terminal 3 is mainly composed of a computer system having one or more processors and memories. The worker terminal 3 is connected to the network 4 via a router 5.

In this embodiment, as shown in Figure 1, the store support system 10 is equipped with three worker terminals 3A, 3B, and 3C carried by three workers 91A, 91B, and 91C, respectively. However, the number of worker terminals 3 equipped in the store support system 10 is not limited to three, and may be one, two, or four or more. Since the multiple worker terminals 3A, 3B, and 3C have the same configuration, Figure 2 illustrates the configuration of only worker terminal 3A, and omits illustrating the configuration of worker terminals 3B and 3C.

The worker terminal 3 is attached to the arm of the worker 91. In this embodiment, as an example, a usage mode is assumed in which the worker terminal 3 is attached to the left arm of the worker 91 so that the worker terminal 3 is visible when the worker 91 is viewed from the right side. More specifically, the worker terminal 3 is attached to the upper arm part between the shoulder and elbow of the left arm of the worker 91, as shown in FIG. 1. Here, the worker terminal 3 is attached so that the long side of the display unit 32 described later is along a straight line connecting the shoulder and elbow. In other words, the long side of the display unit 32 is along the longitudinal direction of the upper arm part. By attaching the worker terminal 3 in such a position, the worker 91 can operate the worker terminal 3 with his/her right hand while looking at the work instruction screen D1 (see FIG. 4) displayed on the worker terminal 3.

Furthermore, an acoustic device, such as an earphone or hearable device, that converts an electrical signal into an acoustic signal and outputs it is connected to the worker terminal 3. The acoustic device is worn, for example, on at least one ear of the worker 91. The worker terminal 3 communicates with the acoustic device, for example, by wireless communication using radio waves as a medium, such as Bluetooth (registered trademark). This allows the worker terminal 3 to notify the worker of work instructions, time signals, etc., by sound (including voice).

As shown in FIG. 2, the worker terminal 3 has a third communication unit 31, a display unit 32, an operation unit 33, and a control unit 34. In the worker terminal 3, one or more processors execute a program recorded in memory, thereby functioning as at least the control unit 34. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-temporary recording medium such as a memory card and provided. In this embodiment, as an example, the worker terminal 3 is a general-purpose smartphone. This worker terminal 3 functions as the worker terminal 3 by installing a dedicated application software (program) and activating this application software.

The third communication unit 31 is, for example, a communication module that communicates bidirectionally between the server device 1 and the management device 2. The third communication unit 31 is connected to the network 4 and communicates with the server device 1 via the network 4. The third communication unit 31 also communicates with the management device 2 by wireless communication using radio waves as a medium, such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). In this embodiment, since the worker terminal 3 is a general-purpose smartphone, when there is an incoming call, such as a work instruction from the management device 2, an incoming call notification is issued to notify the worker 91 of the incoming call, for example, by a ringtone, a light emission function, or a vibration function. An incoming call notification by a ringtone can also be achieved by an acoustic device.

The display unit 32 includes, for example, an LCD (Liquid Crystal Display). The display unit 32 functions as a browser that displays, as an image, at least the data distributed (transmitted) as content from the management device 2.

The operation unit 33 accepts an operation by the worker 91 and outputs a signal corresponding to the operation by the worker 91. In this embodiment, since the worker terminal 3 is a general-purpose smartphone, the operation unit 33 is integrated with the display unit 32 to form a touch panel display. In the touch panel display, the worker terminal 3 determines that an object such as a button has been operated when the operation unit 33 detects an operation (tap, swipe, drag, etc.) of an object such as a button on each screen displayed on the display unit 32. In other words, the display unit 32 and the operation unit 33 function as a user interface that accepts operation input from the worker 91 in addition to various displays.

However, the user interface of the worker terminal 3 is not limited to the display unit 32 and the operation unit 33, and may be realized, for example, by a voice input function and a voice output function of the worker terminal 3. In this case, the worker 91 can operate the worker terminal 3 by voice input, and can receive information presented from the worker terminal 3 by voice output. Voice input and output in the voice input function and voice output function may be realized by an acoustic device.

The control unit 34 controls the third communication unit 31, the display unit 32, and the operation unit 33. The control unit 34 controls the display unit 32 so that a work instruction screen D1 (see FIG. 4), which will be described later, is displayed at least when a work instruction is received from the management device 2. This allows the worker 91 carrying the worker terminal 3 to check the work instruction by looking at the work instruction screen D1 displayed on the display unit 32 of the worker terminal 3. Here, the control unit 34 may display the work instruction screen D1 immediately when the work instruction is received, or may only issue a push notification and display the work instruction screen D1 only after a specific operation (operation of a specific object) is performed by the worker 91.

The screen display method according to this embodiment is used on the graphical user interface (GUI) of a computer system (here, the worker terminal 3). That is, in the worker terminal 3, which is mainly composed of a computer system, one or more processors (control unit 34) execute the screen display method according to this embodiment on the graphical user interface, and display the work instruction screen D1 on the display unit 32. Furthermore, in the worker terminal 3, one or more processors (control unit) on the graphical user interface accept operations by the worker 91 on the work instruction screen D1. Details of the screen display method will be explained in the "(3) Screen display method" section.

In this embodiment, as shown in FIG. 2, the control unit 34 of the worker terminal 3 includes an information acquisition unit 341 and a display processing unit 342 that perform the function of executing the above-mentioned screen display method. That is, the worker terminal 3 includes the information acquisition unit 341 and the display processing unit 342 in the control unit 34. The control unit 34 including the information acquisition unit 341 and the display processing unit 342 performs the function of executing the screen display method, and constructs the screen display system 100. In other words, the screen display system 100 according to this embodiment includes an information acquisition unit 341 and a display processing unit 342. The information acquisition unit 341 acquires acquired information regarding work schedule information that represents the correspondence between the first task, which is the work of the worker 91, and the instruction timing of the first task. The display processing unit 342 displays a work instruction screen D1 for instructing the worker 91 to perform the work on the worker terminal 3 based on the acquired information. The work instruction screen D1 includes a first region R1 (see FIG. 4) and a second region R2 (see FIG. 4). The first area R1 is an area for displaying a first object I1 (see FIG. 4) corresponding to a first task included in the work schedule information, and the second area R2 is an area for displaying a second object I2 (see FIG. 4) corresponding to a second task, which is work of the worker 91 and is different from the first task.

Store computer 6 is installed in store 9. Store computer 6 is a POS system that holds sales information indicating sales at store 9, inventory information indicating the number of items in stock by item at store 9, and the like. "Sales information" in this disclosure includes information such as the time (date and time) of sale of the item, the number sold and the unit price, as well as sales information for various periods such as the sales on that day, the sales on that day, and the sales for the same month of the previous year.

Sensor 7 is installed in store 9. In the present disclosure, "sensor 7" includes a camera equipped with an image sensor. In the present embodiment, as an example, as shown in FIG. 1, sensor 7A is a camera, sensor 7B is a hot water volume sensor incorporated in electric kettle 71, and sensor 7C is an optical sensor incorporated in trash can 72. Sensor 7A captures an image of a specified area in store 9 and outputs image data as a detection result to interface 23. Sensor 7B detects the amount of hot water in electric kettle 71, and sensor 7C detects the amount of trash in trash can 72.

The detection unit 27 is installed in the store 9. The detection unit 27 detects the execution of at least one of the multiple tasks by one of the multiple workers 91 who has been assigned by the assignment unit 17. Basically, the detection unit 27 detects the execution of a task by a worker 91 without relying on the operation of a person (worker 91 or manager, etc.). In other words, the detection unit 27 can detect the execution of a task by a worker even if the worker 91 does not operate the worker terminal 3, etc. to notify that the task has been executed.

In this embodiment, as an example, the detection unit 27 is realized by a receiver that receives a wireless signal. The receiver receives a wireless signal from a transmitter 911 (see FIG. 8A) that outputs (transmits) a wireless signal, such as a beacon or electronic tag carried by each worker 91. Here, the transmitter 911 outputs a wireless signal periodically, irregularly, or in response to a request from the receiver. The wireless signal output by the transmitter 911 includes information (e.g., worker information) for identifying each worker 91 carrying the transmitter 911. When a worker 91 enters a specified reception area, this type of receiver receives the wireless signal from the transmitter 911 carried by the worker 91 and acquires information for identifying the worker 91.

The detection unit 27, which is made up of such a receiver, sets a receivable area in a location in the store 9 where the worker 91 performs a specific task (hereinafter also referred to as a "work area"). As a result, when the worker 91 enters the work area to perform a specific task, the worker 91 enters the receivable area, and the detection unit 27 receives a wireless signal from the transmitter 911 carried by this worker 91. As a result, the detection unit 27 can detect the performance of a specific task by the worker 91.

The occurrence detection unit 28 detects the occurrence of a second task. In other words, the occurrence detection unit 28 detects the occurrence of a second task, which is a task different from a first task, which is a task whose instruction timing is specified in the work schedule information.

In this embodiment, the work related to the second task includes at least one of accounting-related work, cooking-related work, and customer service-related work. Examples of accounting-related work include operating a cash register and selling fast food. Examples of cooking-related work include serving (cooking) fast food. Examples of customer service-related work include age verification.

In this embodiment, as an example, the occurrence detection unit 28 is realized by a human presence sensor. The occurrence detection unit 28, which is made up of a human presence sensor, sets a human detection area in the store 9, for example, in a place where the customer 92 is served by the worker 91 (hereinafter also referred to as the "serving area"). As a result, when the customer 92 enters the serving area to be served by the worker 91, the customer 92 enters the human detection area, and the occurrence detection unit 28 detects this customer 92. As a result, the occurrence detection unit 28 can detect the occurrence of work (second task) caused by the customer 92, such as, for example, working at the cash register.

When the occurrence of the second task is detected by the occurrence detection unit 28, the second task is assigned to one of the multiple workers 91 by the allocation unit 17, and the second task is instructed to one of the multiple workers 91 by the instruction unit 24. In other words, the instruction unit 24 instructs one of the multiple workers 91 to perform the second task based on the detection result of the occurrence detection unit 28. This makes it possible for the instruction unit 24 to instruct the workers 91 not only about the first task, the instruction timing of which is specified in the work schedule information, but also about the second task, the instruction timing of which is not specified in the work schedule information.

The administrator terminal 8 is carried by, for example, the administrator of the store 9 (the owner or manager, etc.). In this embodiment, as an example, the administrator terminal 8 is a general-purpose smartphone. In the administrator terminal 8, one or more processors execute a program recorded in memory, thereby at least functioning as the administrator terminal 8. The program may be pre-recorded in memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-temporary recording medium such as a memory card and provided.

In addition, in this embodiment, as shown in FIG. 2, a data server 40 is connected to the network 4. The data server 40 distributes information such as the weather (including forecasts) around the store 9 and whether or not there are any events (sports matches, concerts, etc.) being held around the store 9 as peripheral information. The peripheral information distributed from the data server 40 is supplied to the server device 1 (acquisition unit 12) as store information relating to the status of the store 9.

(2.2) Operation Hereinafter, the operation of the store support system 10 configured as described above will be described.

(2.2.1) Work Instructions First, the operation of the store support system 10 for issuing work instructions to the worker 91 will be described with reference to Figures 3 and 4. Here, the operation of the performance output unit 18 will be described using as an example the first mode described above, that is, a case where performance information is generated based on a completion notification received from the worker terminal 3. The operation of the performance output unit 18 relating to the second mode described above, that is, the operation where the performance output unit 18 generates performance information based on the detection result of the detection unit 27, will be described in the section "(2.2.5) Generation of performance information".

When the store support system 10 starts operating, as shown in Figure 3, first work schedule information is generated by the schedule generation unit 13 of the server device 1 (S1). The process related to the generation of work schedule information is explained in detail in the section "(2.2.2) Generation of work schedule information". The generated work schedule information is output by the output unit 14 of the server device 1, and transmitted from the server device 1 (first communication unit 11) to the management device 2. The management device 2 stores the received work schedule information in the memory unit 25.

Here, the schedule generation unit 13 generates work schedule information for multiple tasks that are work of multiple workers 91 in the store 9. In other words, the schedule generation unit 13 generates one work schedule that collectively manages the tasks of multiple workers 91A, 91B, and 91C.

Next, the store support system 10 generates and transmits a work instruction in accordance with the work schedule information by the instruction unit 24 of the management device 2 (S2). In this embodiment, when the current time reaches the instruction timing specified in the work schedule information, the instruction unit 24 transmits a work instruction to perform a task corresponding to this instruction timing. The work instruction is transmitted by wireless communication from the second communication unit 21 of the management device 2 to the multiple worker terminals 3A, 3B, 3C registered in the management device 2. Specifically, the management device 2 transmits work instructions to the multiple worker terminals 3A, 3B, 3C all at once (simultaneously) by multicast. The instruction unit 24 is not limited to a configuration in which a work instruction is transmitted at the instruction timing specified in the work schedule information, but may transmit a work instruction including information indicating the instruction timing at a time point prior to the instruction timing, and instruct the worker 91 to perform the task by reservation.

As a result, each worker terminal 3 receives the work instruction (S3). The worker terminal 3 that receives the work instruction notifies the user of the incoming call, for example, by ringing, lighting, or vibrating, and displays the work instruction screen D1 (see FIG. 4) on the display unit 32. At this time, the store support system 10 determines whether the work instruction has been accepted by any of the multiple workers 91A, 91B, 91C using the management device 2 (S4). If the work instruction has not been accepted (S4: No), the store support system 10 returns to process S1 and generates (updates) work schedule information using the schedule generation unit 13 of the server device 1.

On the other hand, when any of the workers 91 accepts the work instruction (S4: Yes), the store support system 10 determines whether the task instructed to be executed in the work instruction has been completed in the management device 2 (S5). If the task has not been completed (S5: No), the store support system 10 returns to process S1 and generates (updates) work schedule information in the schedule generation unit 13 of the server device 1. On the other hand, when the task is completed (S5: Yes), the store support system 10 generates performance information in the performance output unit 18 of the server device 1 and records the performance information in the log recording unit 15 (S6). In other words, the performance information is recorded in the log recording unit 15 of the server device 1 based on the completion notification sent from the worker terminal 3 to the server device 1 via the management device 2 when the task is completed. The performance information recorded in the server device 1 can be viewed as appropriate, for example, on the administrator terminal 8 or the management device 2.

Table 1 below shows an example of work schedule information.

In the example of Table 1, the work schedule information includes work instruction time, priority, task name, status, and person in charge. "Work instruction time" is the time when the work instruction is sent, which corresponds to the instruction timing. "Priority" is a degree indicating the degree to which the task should be prioritized (e.g., three levels: high, medium, and low). "Task name" is a name given to each type of task. "Status" is the progress status of the task (e.g., three levels: completed, pending, and not yet addressed), and "person in charge" is a name used to identify the worker 91 who has performed or is currently performing the task.

An example of performance information is shown in Table 2 below.

In the example of Table 2, the performance information includes the work instruction time, priority, task name, status, standard time, person in charge, acceptance time, completion time, required time, work report and previous work history, and is recorded in the log recording unit 15 for each task. "Standard time" is the standard time required to execute a task, and corresponds to standard time information that indicates the time required from the start to completion of a task. "Acceptance time" is the time when the task was accepted, "completion time" is the time when the task was completed (the time when the completion notification was sent), "required time" is the time required to execute the task, "work report" is the file name of the data indicating the execution of the task, etc., and "previous work history" is information about the previous execution of the task.

The store support system 10 repeatedly executes the processes S1 to S6 described above to issue work instructions to the worker 91 at any time.

When the worker terminal 3 receives a work instruction, the worker terminal 3 displays a work instruction screen D1 as shown in Fig. 4. In this embodiment, as an example, the work instruction screen D1 is a landscape screen in which the horizontal dimension is larger than the vertical dimension as shown in Fig. 4. Fig. 4 shows a specific example of the work instruction screen D1 displayed on the display unit 32, and the dashed lines and reference symbols indicating the areas are shown only for explanatory purposes, and in reality, these dashed lines and reference symbols are not displayed on the display unit 32.

When the worker terminal 3 is worn on the upper arm of the worker 91, the long side of the work instruction screen D1 (the long side of the display unit 32) is aligned with the straight line connecting the shoulder and elbow of the worker 91. In this embodiment, as described above, the worker terminal 3 is worn on the upper arm of the left arm of the worker 91, so that the left side of the work instruction screen D1 is the "shoulder" side, and the right side of the work instruction screen D1 is the "elbow" side, as shown by the arrows in Figure 4. And, since the worker 91 operates the worker terminal 3 with his right hand, the closer he is to the right end (the end on the elbow side), the easier it is to operate the work instruction screen D1.

As shown in FIG. 4, the work instruction screen D1 includes a first area R1 and a second area R2. The first area R1 is an area that displays a first object I1 corresponding to a first task included in the work schedule information. The second area R2 is an area that displays a second object I2 corresponding to a second task, which is work of the worker 91 and is different from the first task. Furthermore, the work instruction screen D1 includes a menu display area R3 and a time display area R4.

The worker 91 performs operations such as accepting the work instruction (S4 in FIG. 3) and reporting the completion of the task (S5 in FIG. 3) on a screen (such as the work instruction screen D1) displayed on the worker terminal 3. The display of the screen displayed on the worker terminal 3 is realized by a screen display method used on the graphical user interface (GUI) of the computer system (here, the worker terminal 3). Therefore, the screen displayed on the worker terminal 3 and the operations performed by the worker 91 on the screen will be explained in detail in the section "(3) Screen display method."

In addition, the above-mentioned operational example shows a case where work schedule information is transmitted from the server device 1 to the management device 2, and work instructions are transmitted from the management device 2 to the worker terminal 3, but this is not limited to this example. For example, the server device 1 may transmit work schedule information or work instructions to the worker terminal 3 without going through the management device 2. Similarly, the above-mentioned operational example shows a case where a completion notification is transmitted from the worker terminal 3 to the server device 1 via the management device 2, but this is not limited to this example. For example, the worker terminal 3 may transmit a completion notification to the server device 1 without going through the management device 2.

Since the store support system 10 of this embodiment is equipped with multiple worker terminals 3A, 3B, and 3C, the following configuration is adopted to prevent duplicate acceptance of work instructions at these multiple worker terminals 3A, 3B, and 3C.

That is, first, the management device 2 simultaneously transmits a work instruction to the multiple worker terminals 3A, 3B, 3C via the instruction unit 24. Here, when the work instruction is accepted at the worker terminal 3, the worker terminal 3 transmits an acceptance notification to the management device 2 or the server device 1. When a first terminal consisting of one worker terminal 3 among the multiple worker terminals 3A, 3B, 3C transmits an acceptance notification to the management device 2 or the server device 1, a notification signal is transmitted to a second terminal consisting of a worker terminal 3 different from the first terminal among the multiple worker terminals 3A, 3B, 3C.

As an example, when one of the multiple worker terminals 3A, 3B, and 3C, the worker terminal 3A, is a first terminal, and each of the worker terminals 3B and 3C is a second terminal. In this case, when the worker terminal 3A, which is the first terminal, sends the acceptance notification, a notification signal is sent to the worker terminals 3B and 3C, which are the second terminals. The notification signal is sent, for example, from the management device 2 or the server device 1 that received the acceptance notification from the first terminal (the worker terminal 3A in the above example) to the second terminal (the worker terminals 3B and 3C in the above example). As a result, the other worker terminals 3B and 3C are notified that one of the multiple worker terminals 3A, 3B, and 3C, the worker terminal 3A, has sent the acceptance notification to the management device 2 or the server device 1. Here, the notification signal may include information for identifying the first terminal, that is, information indicating that the sender (first terminal) of the acceptance notification is the worker terminal 3A in the above example.

When the worker terminal 3 receives the notification signal, it may end the display of the work instruction screen D1 on the display unit 32. In other words, when a work instruction is accepted at one worker terminal 3 (first terminal) among the multiple worker terminals 3A, 3B, 3C, the other worker terminals 3 (second terminals) may receive the notification signal and automatically end the display of the work instruction screen D1.

(2.2.2) Generation of Work Schedule Information Next, the process of generating work schedule information in the store support system 10 according to this embodiment will be described in detail with reference to FIGS. 5 and 6. FIG.

Figure 5 conceptually illustrates the process of generating work schedule information in the schedule generation unit 13 in this embodiment. That is, in this embodiment, the schedule generation unit 13 generates work schedule information based on master data, worker information, non-periodic task information, sales information, visitor forecast data, and sales forecast data.

The "master data" in this disclosure is data used to generate work schedule information, and includes at least reference timing information that is the basis for instruction timing. In other words, the master data is data equivalent to default work schedule information, and the work schedule information is generated by customizing the master data. In this embodiment, the master data further includes standard time information that indicates the time required from the start to the completion of a task. In addition, the "visitor forecast data" in this disclosure is data on the number of future customers estimated (predicted) from the detection results of various sensors 7 installed in the store 9, reservation status, weather around the store 9, whether or not an event will be held around the store 9 and the time period, past visitor performance data, etc. In addition, the "sales forecast data" in this disclosure is data on future sales estimated (predicted) from the detection results of various sensors 7 installed in the store 9, reservation status, weather around the store 9, whether or not an event will be held around the store 9 and the time period, past sales performance data, etc. In addition, the visitor forecast data and sales forecast data may be estimated using, for example, information on campaigns implemented in the store 9, and advertising status including the distribution status of flyers and the distribution status of advertisements.

Here, the worker information, sales information, visitor prediction data, and sales forecast data correspond to store information related to the status of store 9. In other words, the store information includes worker information, sales information, visitor prediction data, and sales forecast data. In addition, in this embodiment, the master data includes information related to tasks in addition to reference timing information, and corresponds to task information. In other words, the task information includes master data and non-periodic task information. In short, the schedule generation unit 13 generates work schedule information based on task information related to tasks and store information related to the status of store 9. The master data can be created or edited as appropriate on the administrator terminal 8 or management device 2, etc.

In this embodiment, the schedule generation unit 13 generates work schedule information based on sales at the store 9. That is, when improving sales at the store 9 is prioritized over reliably executing a task, the schedule generation unit 13 generates work schedule information based on task information and store information so that the task is executed at an effective timing. For example, when the sales at the store 9 would be improved by advancing or delaying the timing of an instruction for a certain task rather than executing the task at the instruction timing specified in the master data, the schedule generation unit 13 changes the instruction timing for the task. In this way, the store support system 10 according to this embodiment generates work schedule information based on task information related to the task and store information related to the status of the store 9, so that it is possible to issue appropriate work instructions according to the status of the store 9.

An example of master data is shown in Table 3 below.

In the example of Table 3, the master data includes the task name, standard time, scheduled start time, advance limit time, postpone limit time, priority, required skill level, advance possible flag, postpone possible flag, postpone possible flag, interrupt possible flag, distance from the cash register, work cycle, and work classification. "Standard time" corresponds to standard time information indicating the time required from the start to completion of a task as described above. "Scheduled start time" is the scheduled time to start a task, and corresponds to reference timing information that is the standard (default value) for the instruction timing. "Advance limit time" is the time that is the limit for advancing a task, and "postponement limit time" is the time that is the limit for postponing a task within a work cycle. "Required skill level" is the skill level of the worker 91 required to execute the task, "advance possible flag" is a flag indicating whether the task can be advanced, and "postponement possible flag" is a flag indicating whether the task can be postponed within a work cycle. The "skill level" in the present disclosure is an index representing the work skill according to the experience level of the worker 91, and is represented in stages, for example, as beginner, regular, or leader. The "postponement flag" is a flag indicating whether the timing of the instruction of the task can be postponed beyond the work cycle, for example to the next day, and the "interruption flag" is a flag indicating whether the task can be interrupted. The "distance from the register" is data indicating the distance from the register (register counter) recommended to the worker 91 who performs the task, and is "inside the register," "near the register," and "far from the register" in order of proximity to the register (register counter). The "work cycle" is the repetition cycle of the periodic task, and the "work classification" is the type of task, and is classified into Q (Quality), S (Service), or C (Cleanliness).

An example of worker information is shown in Table 4 below.

表４の例では、作業者情報は、店員名、勤続年数、スキルレベル、勤務シフト情報及び作業実績評価を含む。「店員名」は作業者９１を識別するための名称、「勤続年数」は作業者９１ごとの店舗９での勤続年数である。「勤務シフト情報」は作業者９１ごとの勤務時間割である。「作業実績評価」は作業者９１が実行したタスクについての評価値（例えば、Ａ，Ｂ，Ｃランクの３段階評価）である。このような作業者情報のうち「勤務シフト情報」については、例えば、管理装置２、作業者端末３又は管理者端末８のいずれかにおいて、作業者９１又は管理者からの操作に応じて適宜入力される。

In the example of Table 4, the worker information includes the clerk name, years of service, skill level, work shift information, and work performance evaluation. "Clerk name" is a name for identifying the worker 91, and "years of service" is the years of service at the store 9 for each worker 91. "Work shift information" is the work schedule for each worker 91. "Work performance evaluation" is an evaluation value for the tasks performed by the worker 91 (e.g., a three-level evaluation of A, B, C ranks). Of such worker information, the "work shift information" is appropriately input in response to an operation by the worker 91 or the administrator, for example, in either the management device 2, the worker terminal 3, or the administrator terminal 8.

FIG. 6 is a flowchart showing the process of generating work schedule information. That is, as shown in FIG. 6, the schedule generating unit 13 sequentially reads the master data, the non-periodic task information, the sales information, the sales forecast data, the visitor forecast data, and the worker information (S11 to S16). Here, for example, the master data, the sales information, the sales forecast data, the visitor forecast data, and the worker information are acquired by the acquiring unit 12 from the management device 2 or the store computer 6. The non-periodic task information is generated by the task generating unit 16. When generating the non-periodic task information, the server device 1 first acquires the detection result (sensing information) of the sensor 7 from the management device 2 by the acquiring unit 12, and further acquires the sales information and the visitor forecast data from the management device 2 or the store computer 6 by the acquiring unit 12. If the task generating unit 16 determines that the situation of the store 9 requires an action by the worker 91, it sets the action as a task, assigns a priority to the task, and generates the non-periodic task information. As a result, the non-periodic task information, which is task information related to the non-periodic task, is automatically generated.

Next, the schedule generation unit 13 predicts the magnitude of the workload for the target period based on the store information (worker information, sales information, customer forecast data, and sales forecast data) and task information (master data and non-periodic task information) read in steps S11 to S16 (S17). In this disclosure, the "workload" refers to the labor of the worker 91 required to execute the task, that is, human resources. In this embodiment, as an example, the workload is measured in man-hours (MH), which are the labor of one worker 91 per hour. For example, if a task requires 30 minutes for one worker 91 to perform, the workload of this task is "0.5". In this disclosure, the "target period" refers to the period that is the target of the generation of work schedule information. In the case where work schedule information is generated for each time period of "8:00-9:00", "9:00-10:00", and "10:00-11:00", each time period is the target period.

Next, the schedule generation unit 13 performs a work timing determination process to determine the timing of the instruction of the task based on the store information and the task information (S18). In other words, the work timing determination process determines the correspondence between the task and the instruction timing. In the work timing determination process, the work load in the target period obtained in process S17 is used to determine the timing of the instruction of the task.

Thereafter, the schedule generation unit 13 generates work schedule information that indicates the correspondence between tasks and instruction timing (S19). In this disclosure, "generating work schedule information" includes the process of updating (changing) an existing work schedule. As a result, the schedule generation unit 13 uses the magnitude of the workload for the target period obtained from the store information to generate the work schedule information.

The schedule generation unit 13 uses the priority of each of the multiple tasks to generate work schedule information. A priority is assigned to each task, and is changed according to store information. In other words, the priority is not a fixed value, but is changed appropriately according to store information (worker information, sales information, customer forecast data, and sales forecast data). The change in priority is performed, for example, as a pre-processing step of the work timing determination process (S18).

Table 5 below shows examples of priority change conditions.

That is, in the example of Table 5, the conditions for changing the priority include four items: "work time constraint," "sales impact," "impact on customer impression," and "relationship between work cycle and elapsed time." "Work time constraint" is a condition for changing the priority depending on whether the timing of the instruction for the task is variable, that is, whether the task can be advanced or delayed as described below. For "work time constraint," the priority is higher the smaller the fluctuation range of the instruction timing (the fluctuation range is minimum when it is fixed). "Sales impact" is a condition for changing the priority depending on the impact on the sales of the store 9. For "sales impact," the priority is higher the greater the impact on sales. "Impact on customer impression" is a condition for changing the priority depending on the impact on the impression given to the customer 92. For "impact on customer impression," the priority is higher the greater the impact on the customer impression. "Relationship between work cycle and elapsed time" is a condition for changing the priority for a periodic task depending on the relationship between the work cycle and the elapsed time since the previous task was completed. Regarding the "relationship between the work cycle and the elapsed time," if the work cycle is shorter than the elapsed time, the priority is high, and if the work cycle is longer than the elapsed time, the priority is low.

To give a specific example, if past sales information indicates that the task of putting out a certain product will have a large impact on sales, the task of putting out this product will be given a high priority. Conversely, if it is estimated that the task of replenishing (preparing) a certain fast food item will have almost no impact on sales, the task of replenishing (preparing) this fast food item will be given a low priority. For example, if customer forecast data indicates that many customers are expected during the lunch hour, the task of cleaning the eat-in space, which has a large impact on customer impressions, will be given a high priority.

In the store support system 10 according to this embodiment, the above-mentioned processes S11 to S19 are repeated, and if the store information changes, the work schedule information is updated (changed) in conjunction with the change in the store information. That is, the schedule generation unit 13 updates the work schedule information in response to the change in the store information. Therefore, the store support system 10 according to this embodiment can issue appropriate work instructions in accordance with the situation of the store 9.

(2.2.3) Allocation Unit In the store support system 10 according to this embodiment, the allocation unit 17 allocates a plurality of tasks in the work schedule information to a plurality of workers 91. In short, in this embodiment, the work schedule information determines which worker 91 is to execute each of the plurality of tasks.

In this embodiment, the instruction unit 24 transmits the generated work instructions only to the worker terminal 3 of the worker 91 to whom the task is assigned, in accordance with the work schedule information received from the server device 1. In other words, the store support system 10 outputs the work instructions in the form of nominating (designating) the worker 91 who will perform the task. In this embodiment, it is assumed that the schedule generation unit 13 generates one piece of work schedule information to be shared by multiple workers 91. In other words, in one piece of work schedule information, each of the multiple tasks is assigned to one of the multiple workers 91.

In the store 9, for example, when a self-checkout register is installed at the checkout counter 94 (see FIG. 8A), a situation may occur in which a worker 91 is not near the customer 92 (i.e., at the checkout counter 94) when the customer 92 purchases an item. In such a situation, it is preferable in terms of efficiency that the work (task) to be performed at the checkout counter 94, such as handling fast food, is performed by a worker 91 who is located close to the checkout counter 94. Therefore, in such a situation, it is preferable that the allocation unit 17 preferentially allocates the work to be performed at the checkout counter 94 to a worker 91 who is closest to the checkout counter 94 among the multiple workers 91.

As an example, the operation of the store support system 10 when a task is assigned to a worker (hereinafter also referred to as the target worker) among multiple workers 91 identified by the "required skill level" and "distance from the cash register" will be described below with reference to Figure 7.

That is, the server device 1 sequentially reads the master data and the worker information (S21, S22). Here, for example, the master data and the worker information are acquired by the acquisition unit 12 from the management device 2 or the store computer 6.

Next, the server device 1 determines whether or not there is a target person based on the master data and the worker information read in steps S21 and S22 in the allocation unit 17 (S23). In step S23, the allocation unit 17 compares the required skill level included in the master data with the skill level included in the worker information, and determines that there is a target person if the skill level is equal to or higher than the required skill level.

If the allocation unit 17 determines that there is no target person (S23: No), the server device 1 returns to process S21. On the other hand, if the allocation unit 17 determines that there is a target person (S23: Yes), the server device 1 acquires store clerk position information (S24). The "store clerk position information" in this disclosure is information that indicates the position of the worker 91 within the store 9, and is monitored by the management device 2 using, for example, the detection result (sensing information) of the sensor 7, and is acquired from the management device 2 by the acquisition unit 12.

Next, the server device 1 uses the allocation unit 17 to determine whether or not there is a target person based on the store clerk position information acquired in process S24 (S25). In process S25, the allocation unit 17 compares the "distance from the register" included in the master data with the store clerk position information, and determines that there is a target person if the position of any worker 91 satisfies the condition specified by "distance from the register". As a specific example, for a task performed inside the register counter 94 such as the above-mentioned fast food counter, the "distance from the register" is set to "inside the register", so that if the worker 91 is near the register, the condition specified by "distance from the register" is met.

If the allocation unit 17 determines that there is no target person (S25: No), the server device 1 returns to process S21. On the other hand, if the allocation unit 17 determines that there is a target person (S25: Yes), the server device 1 transmits a work instruction to the target person (the most suitable person) (S26). At this time, if there are multiple workers 91 who are suitable people, the server device 1 may transmit a work instruction to these multiple workers 91 simultaneously.

However, the present invention is not limited to the above example, and the schedule generating unit 13 may generate work schedule information for each worker 91. In this case, the schedule generating unit 13 generates multiple pieces of work schedule information that correspond one-to-one to the multiple workers 91A, 91B, and 91C.

In addition, the allocation unit 17 may allocate multiple tasks in the work schedule information to multiple workers 91 based only on the skill level of the workers 91. In this case, each task is not necessarily assigned to one worker 91, but is assigned to multiple workers 91 when there are multiple workers 91 with the same skill level, for example.

(2.2.4) Work detection As described above, the detection unit 27 sets a receivable area in the place (work area) where the worker 91 performs a specific task in the store 9, and receives a wireless signal from the transmitter 911 carried by the worker 91 when the worker 91 enters the receivable area. In this way, the detection unit 27 detects the performance of the specific task by the worker 91.

As an example, in the task of cashiering, as shown in Figure 8A, a work area A1 is set inside the cash register counter 94 (the opposite side to the sales floor) and within a certain distance (for example, several tens of centimeters) from the cash register 93. As a result, when a worker 91 moves in front of the cash register 93 to cashier the worker 91 enters work area A1 (receivable area), and the detection unit 27 receives a wireless signal from a transmitter 911 carried by this worker 91. As a result, the detection unit 27 can detect that the worker 91 is performing the task of cashiering.

In the example of Fig. 8A, for the task of handling the cash register, a response area A2 is set outside the cash register counter 94 (the sales floor side) and within a certain distance (for example, several tens of centimeters) from the cash register 93. As a result, when a customer 92 moves in front of the cash register 93 to pay, etc., the customer 92 enters the response area A2 (human detection area), and the occurrence detection unit 28 detects this customer 92. As a result, the occurrence detection unit 28 can detect the occurrence of the task of handling the cash register.

Here, it is preferable that the occurrence detection unit 28 employs the following process so as not to erroneously detect the occurrence of a task when a person (worker 91 or customer 92) passes through the response area A2. For example, the occurrence detection unit 28 may detect the occurrence of a task of handling the cash register when the time that a person (customer 92) has been in the response area A2 reaches a certain time and the person (customer 92) in the response area A2 is facing the cash register 93.

As another example, in the task of replenishing beverages and the like in a large commercial refrigerator 95 (so-called "walk-in replenishment"), as shown in FIG. 8B, a work area A1 is set in the area (walk-in area) behind the refrigerator 95 (the opposite side to the sales floor). As a result, when a worker 91 moves to the walk-in area for walk-in replenishment, the worker 91 enters work area A1 (receivable area), and the detection unit 27 receives a wireless signal from a transmitter 911 carried by this worker 91. As a result, the detection unit 27 can detect that the worker 91 is performing the task of walk-in replenishment.

More specifically, the detection unit 27 detects the start of task execution by the worker 91 by detecting a wireless signal. The wireless signal output by the transmitter 911 includes information (e.g., worker information) for identifying each worker 91 carrying the transmitter 911, so that the detection unit 27 can identify the worker 91 who has started executing the task. In other words, the detection unit 27 can detect at least that the execution of the task has started, as well as which worker 91 among the multiple workers 91 is executing the task. In other words, the detection unit 27 can detect the execution of a task in a form that corresponds to the worker 91 who is executing the task. And, since the task is assigned to one of the workers 91 by the assignment unit 17, the assignment information, that is, information on which worker 91 is assigned to which task, is already known.

Therefore, by using such allocation information, the detection unit 27 can detect the performance of a task by the worker 91 to whom the task is assigned. For example, if the task of "operating the cash register" is assigned to worker 91A among workers 91A, 91B, and 91C, the detection unit 27 detects the performance of "operating the cash register" by worker 91A when worker 91A enters work area A1 around cash register 93. In this case, even if workers 91B and 91C, who are not assigned the task of "operating the cash register", enter work area A1 around cash register 93, the detection unit 27 does not detect the performance of "operating the cash register".

The detection unit 27 that receives the wireless signal from the transmitter 911 may notify the management device 2 or the server device 1 of the detection result, for example, via the worker terminal 3. The management device 2 or the server device 1 may associate the execution of a task with the worker 91 who is the executor of the task.

Furthermore, the detection unit 27 further detects the completion of at least one of the multiple tasks. For example, the detection unit 27 detects the completion of a task by the worker 91 when the detection unit 27 detects a wireless signal from the transmitter 911 and then is unable to detect the wireless signal. In other words, when the worker 91 completes a specific task and leaves the work area A1, the worker 91 leaves the reception area, and the detection unit 27 is unable to receive the wireless signal from the transmitter 911 carried by the worker 91. This allows the detection unit 27 to detect the completion of the specific task.

(2.2.5) Generation of performance information The following describes the operation of the performance output unit 18 according to the second aspect described above, that is, the operation when the performance output unit 18 generates performance information based on the detection result of the detection unit 27.

The performance output unit 18 basically generates performance information representing the execution status of a task by each worker 91 based at least on the detection result of the detection unit 27, and outputs the performance information (records it in the log recording unit 15). In other words, the detection unit 27 can detect the execution of a task by a worker 91 to whom a task is assigned, and therefore the performance output unit 18 can automatically generate performance information based on the detection result.

For example, when the task "operating the cash register" is assigned to the worker 91A among the workers 91A, 91B, and 91C, the detection unit 27 detects the execution of "operating the cash register" by the worker 91A when the worker 91A enters the work area A1 around the cash register 93. In this case, the performance output unit 18 automatically generates performance information indicating that the worker 91A has performed "operating the cash register" based on the detection result of the detection unit 27. On the other hand, even if the workers 91B and 91C, who are not assigned the task "operating the cash register", enter the work area A1 around the cash register 93, the detection unit 27 does not detect the execution of "operating the cash register", so the performance output unit 18 does not generate performance information indicating the execution of "operating the cash register". In this way, when the detection unit 27 detects the execution of the task by the worker 91, the performance output unit 18 automatically generates performance information based on the detection result of the detection unit 27 and outputs the performance information.

In addition, in this embodiment, the detection unit 27 detects both the start and completion of a task. Therefore, the time required to execute a task (required time) can also be included in the performance information.

More specifically, when the detection unit 27 detects that the worker 91 to whom the task is assigned has performed the task, the detection result of the detection unit 27 is transmitted from the management device 2 to the server device 1. The server device 1 generates performance information in the performance output unit 18 based on the detection result of the detection unit 27, and records the performance information in the log recording unit 15. The performance information recorded in the server device 1 can be viewed as appropriate, for example, on the administrator terminal 8 or the management device 2. The performance information generated at this time is, for example, the same as the information exemplified in "Table 2" above. In this case, the "reception time" in the performance information is the time when the start of task execution is detected by the detection unit 27, and the "completion time" is the time when the completion of the task is detected by the detection unit 27.

In addition, a part of the function of the detection unit 27 may be distributed to the server device 1. As an example, the function of the detection unit 27 to compare assignment information (information regarding which worker 91 is assigned to which task) may be provided in the server device 1. In this case, the receiver provided in the store 9 needs to detect at least that execution of a task has started, as well as which of the multiple workers 91 is executing the task, and transmit only the result to the server device 1.

In this way, in the store support system 10 according to this embodiment, the detection unit 27 detects the execution of a task by a worker 91 to whom a task has been assigned, and based on the detection result, performance information indicating the execution status of the task by each worker 91 can be automatically generated and output. Therefore, when starting or completing a task, the worker 91 can leave a record of work performance without recording performance information.

In addition, in this embodiment, as described above, when performance information is generated based on the detection results of the detection unit 27, the performance information is generated using work schedule information, worker information, and the work status of each worker 91 in addition to the detection results of the detection unit 27.

That is, the performance output unit 18 can generate performance information based on the work schedule information, taking into account the correspondence between the task and the instruction timing. As an example, the performance output unit 18 validates the detection result of the detection unit 27 only during a judgment period set before and/or after the instruction timing, and invalidates the detection result of the detection unit 27 outside the judgment period. As a result, when the detection unit 27 detects the execution of a specific task by the worker 91 to whom a specific task is assigned during the judgment period, the performance output unit 18 generates and outputs performance information about the task. On the other hand, when the detection unit 27 detects the execution of a specific task by the worker 91 to whom a specific task is assigned outside the judgment period, the performance output unit 18 does not generate performance information about the task. As a result, it is possible to leave performance information about the task only when the detection unit 27 detects the execution of the task by the worker 91 to whom a task is assigned during a judgment period set before and/or after the instruction timing. In other words, since there is a correlation between the execution of a task and the timing of instructions, such as the high possibility that the worker 91 will not be performing the assigned task outside the judgment period, it is possible to improve the reliability of the performance information generated by the performance output unit 18 by utilizing this correlation.

In addition, the performance output unit 18 can generate performance information based on the worker information, taking into account the skills of each worker 91. As an example, the performance output unit 18 validates the detection result of the detection unit 27 only for the worker 91 whose skill level corresponds to the required skill level of the task, and invalidates the detection result of the detection unit 27 for the worker 91 whose skill level does not correspond to the required skill level of the task. As a result, when a specific task is assigned and the detection unit 27 detects the execution of the specific task by the worker 91 whose skill level corresponds to the required skill level of the task, the performance output unit 18 generates and outputs performance information for this task. On the other hand, when the detection unit 27 detects the execution of the specific task by the worker 91 who is assigned a specific task but whose skill level does not correspond to the required skill level of the task, the performance output unit 18 does not generate performance information for this task (specific task). As a result, for a worker 91 whose skill level reaches the required skill level of a task, it is possible to leave performance information for the task only when the detection unit 27 detects that the task has been performed by the worker 91 to whom the task has been assigned. In other words, by utilizing the fact that a worker 91 whose skill level does not reach the required skill level of a task is highly likely not to have performed the assigned task (specific task), it is possible to improve the reliability of the performance information generated by the performance output unit 18.

In addition, the performance output unit 18 can generate performance information based on the work status of each of the multiple workers 91, taking into account the current status of each worker 91 (whether or not they are performing another task, etc.). As an example, the performance output unit 18 validates the detection result of the detection unit 27 only for workers 91 who are not performing any tasks (i.e., workers 91 who are free), and invalidates the detection result of the detection unit 27 for workers 91 who are performing another task. As a result, when a specific task is assigned and the detection unit 27 detects the execution of the specific task by a worker 91 who is free, the performance output unit 18 generates and outputs performance information for this task. On the other hand, when the detection unit 27 detects the execution of the specific task by a worker 91 who is assigned a specific task but is performing another task, the performance output unit 18 does not generate performance information for this task (specific task). As a result, for a free worker 91, it is possible to leave performance information for the task only when the detection unit 27 detects that the task is being performed by the assigned worker 91. In other words, it is possible to improve the reliability of the performance information generated by the performance output unit 18 by utilizing the fact that the worker 91 is highly likely not performing the assigned task (specific task) while performing another task.

In this way, when the performance output unit 18 generates performance information based on the detection results of the detection unit 27, it is possible to improve the reliability of the performance information by using work schedule information, worker information, and the work status of each worker 91 in addition to the detection results of the detection unit 27.

(2.2.6) Other Functions The store support system 10 according to this embodiment has a function of issuing work instructions to the worker 91, as well as a function of age verification processing to assist the worker 91 in verifying the age of the customer 92 (see FIG. 1 ). In other words, the store support system 10 has a function of managing the work of the worker 91 in the store 9 and a function of age verification processing.

In this disclosure, "age verification" refers to, for example, when selling products such as tobacco and alcoholic beverages, the sale of which to persons under a certain age is restricted by law, etc., a verifier (seller, etc.) verifying whether the target person (purchaser, etc.) is above a certain age.

During the age verification process, the management device 2 transmits a request signal including image data of an image captured by the sensor 7A (camera) of the customer 92 who is the subject of age verification to the worker terminal 3. The worker terminal 3 uses the image data included in the received request signal to display an age verification screen including an image of the customer 92. In this state, the worker 91 confirms the age of the customer 92 by looking at the age verification screen displayed on the worker terminal 3. At this time, when the worker terminal 3 receives an operation from the worker 91 to select success or failure of the age verification, it transmits a response signal including the result of the age verification corresponding to that operation to the management device 2.

In short, in the store support system 10, image data of an image of the customer 92 is sent from the management device 2 to the worker terminal 3, so that the worker 91 can confirm the age of the customer 92 by viewing the image of the customer 92 on the age confirmation screen displayed on the worker terminal 3. Moreover, the result of the age confirmation performed on the worker terminal 3 side is returned from the worker terminal 3 to the management device 2, which is the sender of the request signal, so that the series of processes for age confirmation are started and completed on the management device 2 side.

Therefore, according to the store support system 10, it is possible to sell specific products that require age verification at the time of sale, such as alcoholic beverages and tobacco, while automating (unmanning) at least a part of the sales process by introducing, for example, self-checkouts. Moreover, as long as the worker 91 carries the worker terminal 3, even if the worker 91 is located away from the customer 92, he or she can verify the age of the customer 92 without moving from the location. Furthermore, the customer 92 does not need to wait for the arrival of the worker 91 (store clerk) who is located away from the customer 92 to verify the age. As a result, according to the store support system 10, it is possible to realize age verification while reducing the effort required by people (the worker 91 and the customer 92).

Here, if age verification processing is included in the task, the efficiency of the work can be improved by, for example, sending a work instruction to execute the task and data for the age verification processing together from the management device 2 to the worker terminal 3. Specifically, when selling a specific product that requires age verification to a customer 92, the management device 2 sends a work instruction to the worker terminal 3 instructing the worker 91 to perform the age verification processing task. At this time, the management device 2 sends information necessary for the worker 91 to carry out the age verification processing using the worker terminal 3, i.e., information such as an image of the customer 92, to the worker terminal 3 together with the work instruction.

When the worker terminal 3 receives a work instruction for the age verification process as described above, the worker 91 first performs an operation to accept the work instruction. After that, the worker 91 who performed the acceptance operation performs the operations necessary for the age verification process, such as checking the image displayed on the worker terminal 3 and selecting whether the age verification was successful or unsuccessful. A completion notification including the result of the age verification is sent to the management device 2 from the worker terminal 3 of the worker 91 who accepted the age verification process.

(3) Screen Display Method The screen display method according to this embodiment is realized on a graphical user interface (GUI) of a computer system. The screen display method according to this embodiment will be described below with reference to Figs. 9A to 15C. Figs. 9A to 15C show specific examples of screens displayed on the display unit 32, and the dashed lines and reference symbols indicating areas are merely shown for the purpose of explanation, and in reality, these dashed lines and reference symbols are not displayed on the display unit 32. In Figs. 9A to 15C, the finger F1 of a person (worker 91) who operates (tap, swipe, drag, etc.) an object such as a button on each screen displayed on the display unit 32, and the finger F1 and its movement are shown by imaginary lines (two-dot chain lines).

(3.1) Acceptance and Completion of the First Task First, the transition of the screens displayed on the worker terminal 3 when the worker 91 performs operations on the work instruction screen D1 to accept a work instruction (S4 in FIG. 3) and report completion of the task (S5 in FIG. 3) will be described with reference to FIGS. 9A to 9C.

As described above, the screen display method according to this embodiment includes an acquisition process and a display process. The acquisition process is a process for acquiring acquired information. The acquired information is information about the work schedule information that represents the correspondence between the first task, which is the work of the worker 91, and the instruction timing of the first task. In this embodiment, since the worker terminal 3 receives a work instruction based on the work schedule information, the acquisition process acquires this work instruction as acquired information. In other words, the information about the work schedule information acquired in the acquisition process includes the work instruction. The display process is a process for displaying a work instruction screen D1, as shown in FIG. 9A, on the worker terminal 3 based on the acquired information acquired in the acquisition process. The work instruction screen D1 is a screen for instructing the worker 91 to perform work. Since the work instruction screen D1 is displayed based on the acquired information (here, the work instruction), the display content changes depending on the work schedule information (or the work instruction).

Here, the work instruction screen D1 includes a first area R1 and a second area R2, as shown in Fig. 9A. The first area R1 is an area for displaying a first object I1 corresponding to a first task included in the work schedule information. The second area R2 is an area for displaying a second object I2 corresponding to a second task, which is work of the worker 91 and is different from the first task.

In this embodiment, the first region R1 and the second region R2 are set so that when the work instruction screen D1 is divided vertically (along the short side of the work instruction screen D1), the lower side is the first region R1 and the upper side is the second region R2. Here, as shown in FIG. 9A, the first region R1 has a larger vertical dimension of the work instruction screen D1 than the second region R2. Therefore, in the vertical direction of the work instruction screen D1, the first region R1 occupies more than half of the work instruction screen D1.

Furthermore, as described above, the work instruction screen D1 further includes a menu display area R3 and a time display area R4 in addition to the first area R1 and the second area R2. The menu display area R3 and the time display area R4 are arranged above the second area R2 in the work instruction screen D1. The menu display area R3 and the time display area R4 are arranged in the horizontal direction of the work instruction screen D1 (the direction along the long side of the work instruction screen D1), and the time display area R4 is arranged to the right of the menu display area R3. The menu display area R3 is an area that displays, as an example, a character string that identifies the worker 91, "Staff A," and a menu button. The time display area R4 is an area that displays the current time (including the date), and as an example, the character string "2018/09/14 (Fri) 19:17" is displayed.

To explain the work instruction screen D1 in more detail, a plurality of first objects I1 are displayed in the first area R1. The plurality of first objects I1 are arranged in an order according to at least one of the priority and instruction timing of the corresponding first tasks. In the example of FIG. 9A, five first objects I11 to I15 are displayed in the first area R1. When no particular distinction is made between the five first objects I11 to I15, each of the five first objects I11 to I15 is also simply referred to as a "first object I1."

Each first object I1 has a rectangular shape that is long in the vertical direction of the work instruction screen D1. Each first object I1 is an object for receiving an operation (tap) from the worker 91. Each first object I1 includes specific information for identifying the corresponding first task, and as an example, includes an icon (image) representing the first task as the specific information. Furthermore, each first object I1 includes time information representing the instruction timing of the corresponding first task, and as an example, includes a character string representing the time of the instruction timing as the time information. In FIG. 9A, as an example, the first object I11 corresponds to replenishing (preparing) fast food, the first object I12 corresponds to putting out products, the first object I13 corresponds to displaying, the first object I14 corresponds to checking, and the first object I15 corresponds to inspection. And, for example, the first object I11 includes an icon representing the first task of replenishing (preparing) fast food, and a character string "18:00" representing the time of the instruction timing.

These five first objects I11 to I15 are arranged in the order of first objects I11, I12, I13, I14, and I15 from the right side on the work instruction screen D1, with first object I11 at the right end. The arrangement order of the five first objects I11 to I15 is based on at least one of the priority and instruction timing of the corresponding first tasks.

In this embodiment, the order of the five first objects I11 to I15 is determined according to both the priority and the instruction timing of the first task. Specifically, the multiple first objects I1 are arranged in chronological order so that the instruction timing is arranged from the right side in the order of earliest to latest on the work instruction screen D1. Furthermore, if there are multiple first objects I1 with the same instruction timing, the multiple first objects I1 with the same instruction timing are arranged in order of priority so that the multiple first objects I1 with the same instruction timing are arranged from the right side in the order of highest to lowest priority on the work instruction screen D1. In the example of FIG. 9A, the first object I11 with the instruction timing of "18:00" is located at the right end, and the first objects I12 to I15 with the instruction timing of "19:00" are located to the left of the first object I11. Then, for the first objects I12 to I15 with the same instruction timing, the first objects I12 and I13 with the priority of "medium" are located on the right side, and the first objects I14 and I15 with the priority of "low" are located on the left side.

However, the order of the first objects I11 to I15 may be determined by at least one of the priority and the instruction timing of the corresponding first tasks. Therefore, the order of the first objects I11 to I15 may be determined, for example, only by the corresponding first tasks or only by the instruction timing of the corresponding first tasks.

As described above, assuming that the worker 91 operates the worker terminal 3 with his/her right hand, the closer to the right end (the end on the elbow side) on the work instruction screen D1, the easier it is to operate. Therefore, of the five first objects I11 to I15, the first object I11 is located in a position that is easiest to operate, followed by the first objects I12, I13, I14, and I15 in that order. As a result, the first object I1 will be located in a position that is easier to operate on the work instruction screen D1 the earlier the instruction timing for the corresponding task (first task) is or the higher the priority is.

The display mode of the first object I1 differs depending on the priority of the corresponding first task. In the present disclosure, "display mode" includes, for example, color (display color), text font (including size and thickness), movement (including deformation and blinking, etc.), icon shape and size (size), etc. In this embodiment, the display color of the first object I1 differs depending on the priority of the corresponding first task. As an example, the first object I1 corresponding to a first task with a "high" priority is red, the first object I1 corresponding to a first task with a "medium" priority is yellow, and the first object I1 corresponding to a first task with a "low" priority is blue.

In addition, a plurality of second objects I2 are displayed in the second region R2. In the example of Fig. 9A, two second objects I21 and I22 are displayed side by side in the second region R2. When there is no particular distinction between the two second objects I21 and I22, each of the two second objects I21 and I22 is also simply referred to as a "second object I2."

Each second object I2 has a rectangular shape that is long in the horizontal direction of the work instruction screen D1. Each second object I2 is an object for receiving an operation (tap) from the worker 91. Each second object I2 includes specific information for identifying the corresponding second task, and includes, as an example, an icon (image) and text (character string) representing the second task as the specific information. In FIG. 9A, as an example, the second object I21 corresponds to cash register handling, and the second object I22 corresponds to fast food handling (FF handling). For example, the second object I21 includes an icon and text ("cash register handling") representing the second task of cash register handling.

9A, the first object I1 displayed on the work instruction screen D1 is the first object I1 corresponding to the task (first task) for which a work instruction has currently been issued, among the tasks included in the work schedule information. In other words, the first object I1 corresponding to the task to be performed by the worker 91 is displayed in the first region R1 of the work instruction screen D1. Therefore, the first object I1 displayed in the first region R1 of the work instruction screen D1 is only the first object I1 corresponding to the task (first task) that is in an uncompleted state. Therefore, the first object I1 displayed in the first region R1 is a variable object that changes from time to time as the task is completed.

On the other hand, the second object I2 displayed on the work instruction screen D1 corresponds to a task (second task) for which the timing of instruction is not specified in the work schedule information. In other words, the timing for the worker 91 to perform the task corresponding to the second object I2 is not specified, and the worker 91 can perform it at any time. Therefore, there is no concept of completion/incompletion for the task (second task) corresponding to the second object I2 displayed in the second area R2 of the work instruction screen D1. Therefore, the second object I2 displayed in the second area R2 is a fixed object that does not change over time.

In the following, an example will be described in which, with the above-mentioned work instruction screen D1 displayed, worker 91 executes a task (first task) of "stocking products" corresponding to the instruction timing of "19:00". Furthermore, as an example, it is assumed here that, as shown in FIG. 1, worker 91A accepts a work instruction among worker 91A stocking products, worker 91B cleaning, and worker 91C serving customers.

In this case, the worker 91A looks at the work instruction screen D1 displayed on the worker terminal 3A carried by the worker 91A, and operates (tap) the first object I12 on the work instruction screen D1 shown in FIG. 9A with the finger F1 to accept the work instruction. As a result, an acceptance notice indicating that the work instruction has been accepted is sent from the worker terminal 3A to the management device 2 (S4 in FIG. 3: Yes). At this time, the display of the worker terminal 3A transitions from the work instruction screen D1 shown in FIG. 9A to the work selection screen D2 shown in FIG. 9B. In other words, the screen display method according to this embodiment has a first transition process. The first transition process is a process of changing the display of the worker terminal 3 from the work instruction screen D1 to the work selection screen D2 when an operation to select the first task related to the first object I1 displayed in the first region R1 is accepted. The operation of the worker 91 here is not limited to tapping the first object I1, and may be, for example, an operation using a pointing device, a voice input, a gesture input, or the like.

Here, the work selection screen D2 includes a detailed object I3 instead of the first region R1, as shown in Figure 9B. Therefore, in the vertical direction of the work selection screen D2, the detailed object I3 occupies more than half of the work selection screen D2. The work selection screen D2 is similar in configuration to the work instruction screen D1 except for the first region R1. In other words, the work selection screen D2 includes the second region R2, the menu display region R3, and the time display region R4 in addition to the detailed object I3.

The detailed object I3 is an object related to the task (first task) corresponding to the first object I1 selected on the work instruction screen D1 and has a larger display area than the first object I1. That is, in this embodiment, the work schedule information includes a plurality of first tasks. In the first transition process, when an operation to select the first object I1 corresponding to a selected task consisting of one of the plurality of first tasks is received on the work instruction screen D1, the work selection screen D2 including the detailed object I3 is displayed. The detailed object I3 is an object related to the selected task and has a larger display area than the first object I1. The operation of the worker 91 here is not limited to tapping the first object I1, and may be, for example, an operation using a pointing device, voice input, gesture input, etc.

Furthermore, in this embodiment, the work selection screen D2 includes a complete button I31 and a cancel button I32 within the detail object I3. The complete button I31 displays the character string "Complete," and the cancel button I32 displays the character string "Cancel." The complete button I31 is operated (tapped) by the worker 91 when the worker 91 completes a task (work), and the cancel button I32 is operated (tapped) by the worker 91 when the worker 91 interrupts the task (work).

After completing the task corresponding to the detailed object I3 (here, "putting out the product"), the worker 91A operates (tap) the completion button I31 with the finger F1 on the work selection screen D2 displayed on the worker terminal 3A to report the completion of the work. As a result, the worker terminal 3A sends a completion notification indicating that the task has been completed to the management device 2 (S5 in FIG. 3: Yes), and the display of the work selection screen D2 ends. At this time, the display of the worker terminal 3A transitions from the work selection screen D2 shown in FIG. 9B to the work instruction screen D1 shown in FIG. 9C. In other words, the screen display method according to this embodiment further includes a completion process that sets the state of the selected task to a completed state. Then, in the screen display method according to this embodiment, when the operation of the worker 91 indicating that the selected task has been completed is received on the work selection screen D2, the completion process is executed. The operation of the worker 91 here is not limited to tapping the completion button I31, and may be, for example, an operation using a pointing device, a voice input, a gesture input, or the like.

In the work instruction screen D1 shown in Fig. 9C, the first object I1 corresponding to the completed task (here, "putting out products") has been deleted. In other words, in the work instruction screen D1 shown in Fig. 9C, the first object I1 corresponding to the task "putting out products" has been deleted, and a first object I15 corresponding to the task (first task) with the instruction timing of "20:00" has been added.

The work instruction screen D1 shown in FIG. 9C is also displayed on the worker terminals 3B and 3C carried by the workers 91B and 91C. However, on the worker terminals 3B and 3C, the work instruction screen D1 changes when the work selection screen D2 is displayed on the worker terminal 3A, that is, when the task corresponding to the detailed object I3 (here, "stock the product") becomes accepted. In short, in this embodiment, the first object I1 is erased from the first region R1 when the corresponding first task becomes accepted. However, this is not the only example, and the first object I1 may be erased from the first region R1 when the corresponding first task becomes completed.

In other words, the screen display method according to this embodiment further includes a deletion process. The deletion process is a process of deleting a first object I1, the state of which of the corresponding first task has become an accepted state or a completed state, from the first region R1.

On the other hand, when the worker 91A interrupts the task corresponding to the detailed object I3 (here, "stocking the product"), he operates (tap) the cancel button I32 with his finger F1 on the task selection screen D2 displayed on the worker terminal 3A. This causes an interruption notification indicating that the task has been interrupted to be sent from the worker terminal 3A to the management device 2. The management device 2 determines that the task has not been completed when a predetermined time has passed since the instruction timing while the interruption notification has been received from the worker terminal 3A that accepted the work instruction, or while no completion notification has been received from the worker terminal 3A (S5: No in FIG. 3). In this way, even if the task is not completed, that is, when a predetermined time has passed since the instruction timing while the task is incomplete, the first object I1 corresponding to this task (first task) is deleted from the first area R1 of the work instruction screen D1.

In other words, the screen display method according to this embodiment further includes a timed erasure process. The timed erasure process is a process of erasing the first object I1 from the first region R1 when the erasure timing determined by at least one of the priority and the instruction timing of the corresponding first task has arrived. Here, as an example in this embodiment, the erasure timing is the timing when a timeout time according to the priority has elapsed from the instruction timing. In other words, the timeout time from the instruction timing to the erasure timing differs depending on the priority of the task. As an example, the timeout time of a first task with a "high" priority is 5 hours, the timeout time of a first task with a "medium" priority is 3 hours, and the timeout time of a first task with a "low" priority is 1 hour. Therefore, in this embodiment, the erasure timing is determined by both the priority and the instruction timing of the corresponding first task.

However, the timing of erasure only needs to be determined by at least one of the priority and instruction timing of the corresponding first task, and so may be determined, for example, only by the corresponding first task, or only by the instruction timing of the corresponding first task.

(3.2) Spontaneous Work Next, transition of the screen displayed on the worker terminal 3 when a task (first task) occurs suddenly will be described with reference to FIGS. 10A to 10C.

In the following, an example will be described in which, with the work instruction screen D1 as shown in Fig. 10A displayed, a task (first task) called "change garbage bag" corresponding to the instruction timing of "13:00" occurs suddenly. Furthermore, as an example, it is assumed here that the current time is "12:00".

As a premise, as described above, in this embodiment, the server device 1 generates non-periodic task information based on the detection results (sensing information) of the sensor 7, etc. This automatically generates non-periodic task information, which is task information related to non-periodic tasks. Such non-periodic tasks may occur suddenly. For example, when the sensor 7C detects that the amount of garbage in the garbage bin 72 has reached an upper limit, the "change garbage bag" task corresponding to the instruction timing of "13:00" occurs ahead of schedule as an non-periodic task.

At this time, the display of the worker terminal 3 transitions from the work instruction screen D1 shown in Fig. 10A to the work instruction screen D1 shown in Fig. 10B. In the work instruction screen D1 shown in Fig. 10B, a first object I11 corresponding to a suddenly occurring non-periodic task (here, "changing garbage bags") has been added. Although the instruction timing for this first object I11 is "13:00", it is particularly urgent and is therefore displayed at the right end of the five first objects I11 to I15. As a result, the first object I15 included in the work instruction screen D1 shown in Fig. 10A is pushed off the screen and hidden in the work instruction screen D1 of Fig. 10B.

In this way, the screen display method according to this embodiment further includes a sudden display process. The sudden display process is a process for displaying a first object I1 corresponding to a first task in the first area R1 at a timing earlier than the instruction timing associated with the work schedule information. In other words, according to the sudden display process, a first object I11 corresponding to a suddenly occurring non-periodic task (here, "changing garbage bags") is displayed in the first area R1 of the work instruction screen D1 at a timing earlier than the original instruction timing of "13:00".

The subsequent processing is the same as that described in "(3.1) Acceptance and Completion of the First Task." That is, the worker 91 looks at the work instruction screen D1 displayed on the worker terminal 3 carried by the worker 91, and operates (tap) the first object I11 on the work instruction screen D1 shown in FIG. 10B with the finger F1 to accept the work instruction. As a result, the display on the worker terminal 3 transitions from the work instruction screen D1 shown in FIG. 10B to the work selection screen D2 shown in FIG. 10C.

(3.3) Acceptance and Completion of the Second Task Next, the transition of the screen displayed on the worker terminal 3 when the second task is accepted and completed will be described with reference to FIGS. 11A to 11C.

In the following, an example will be described in which worker 91 executes a task called "handling the cash register" (second task) when the work instruction screen D1 as shown in Fig. 11A is displayed. Furthermore, as an example, it is assumed here that, of worker 91A performing stocking work, worker 91B performing cleaning work, and worker 91C serving customers as shown in Fig. 1, worker 91A accepts a work instruction.

In this case, the worker 91A looks at the work instruction screen D1 displayed on the worker terminal 3A carried by the worker 91A, and operates (tap) the second object I21 on the work instruction screen D1 shown in FIG. 11A with the finger F1 to accept the work instruction. As a result, an acceptance notice indicating that the work instruction has been accepted is sent from the worker terminal 3A to the management device 2 (S4 in FIG. 3: Yes). At this time, the display of the worker terminal 3A transitions from the work instruction screen D1 shown in FIG. 11A to the work acceptance screen D3 shown in FIG. 11B. In other words, the screen display method according to this embodiment has a second transition process. The second transition process is a process of changing the display of the worker terminal 3 from the work instruction screen D1 to the work acceptance screen D3 when an operation to select the second task related to the second object I2 displayed in the second region R2 is accepted. The operation of the worker 91 here is not limited to tapping the second object I2, and may be, for example, an operation using a pointing device, a voice input, a gesture input, or the like.

Here, as shown in FIG. 11B, the work acceptance screen D3 includes a situation object I4 instead of the first region R1. Therefore, in the vertical direction of the work acceptance screen D3, the detailed object I3 occupies more than half of the work acceptance screen D3. The work acceptance screen D3 also includes a request region R5 instead of the second region R2. The request region R5 is an area that displays a request object I5 for a support request. Here, the second object I2 is replaced with the request object I5, and therefore the two request objects I51 and I52 are displayed in the request region R5. When there is no particular distinction between the two request objects I51 and I52, each of the two request objects I51 and I52 is also simply referred to as a "request object I5."

The work acceptance screen D3 has the same configuration as the work instruction screen D1, except for the first area R1 and the second area R2. In other words, the work acceptance screen D3 includes a menu display area R3 and a time display area R4 in addition to the situation object I4 and the request area R5.

The situation object I4 is an object related to the task (second task) corresponding to the second object I2 selected on the work instruction screen D1 and has a larger display area than the second object I2. That is, in the present embodiment, in the second transition process, when an operation to select the second object I2 corresponding to the selected task consisting of the second task is accepted on the work instruction screen D1, a work acceptance screen D3 including the situation object I4 is displayed. The situation object I4 is an object related to the selected task and has a larger display area than the second object I2. The operation of the worker 91 here is not limited to tapping the second object I2, and may be, for example, an operation using a pointing device, voice input, gesture input, or the like.

In addition, in this embodiment, the work acceptance screen D3 includes a completion button I41 in the situation object I4. The completion button I41 displays the character string "Complete." The completion button I41 is operated (tapped) by the worker 91 when the worker 91 completes the task (work).

After completing the task corresponding to the situation object I4 (here, "cash register handling"), the worker 91A operates (tap) the completion button I41 with the finger F1 on the work acceptance screen D3 displayed on the worker terminal 3A to report the completion of the work. As a result, the worker terminal 3A transmits a completion notification indicating that the task has been completed to the management device 2 (S5 in FIG. 3: Yes), and the display of the work acceptance screen D3 ends. At this time, the display of the worker terminal 3A transitions from the work acceptance screen D3 shown in FIG. 11B to the work instruction screen D1 shown in FIG. 11C. In other words, in the screen display method according to this embodiment, when the operation of the worker 91 indicating that the selected task has been completed is accepted on the work acceptance screen D3, the completion process is executed. The operation of the worker 91 here is not limited to tapping the completion button I41, and may be, for example, an operation using a pointing device, a voice input, a gesture input, or the like.

The work instruction screen D1 shown in FIG. 11C is the same as before the work instruction was accepted. In other words, when the second task is completed, the corresponding second object I2 is not deleted. Therefore, the work instruction screen D1 to which the work acceptance screen D3 shown in FIG. 11B transitions is the same as the work instruction screen D1 in FIG. 11A before the transition to the work acceptance screen D3.

(3.4) Acceptance and Completion of a Second Task While Executing a First Task Next, the transition of the screen displayed on the worker terminal 3 when accepting and completing a second task while executing a first task will be described with reference to Figures 12A to 12C. In this case, the basic process is the same as in "(3.3) Acceptance and Completion of a Second Task," so the description will be omitted below as appropriate.

In the following, an example will be described in which worker 91 executes a task called "serving fast food" (second task) when the task selection screen D2 as shown in Fig. 12A is displayed. Furthermore, as an example, it is assumed here that, as shown in Fig. 1, worker 91A accepts a task instruction among worker 91A performing stocking work, worker 91B performing cleaning work, and worker 91C performing customer service.

In this case, the worker 91A looks at the work selection screen D2 displayed on the worker terminal 3A carried by the worker 91A, and operates (tap) the second object I22 on the work selection screen D2 shown in Fig. 12A with the finger F1 to accept the work instruction. As a result, an acceptance notification indicating that the work instruction has been accepted is sent from the worker terminal 3A to the management device 2. At this time, the display of the worker terminal 3A transitions from the work selection screen D2 shown in Fig. 12A to the work acceptance screen D3 shown in Fig. 12B.

After completing the task corresponding to the situation object I4 (here, "Handling the cash register"), the worker 91A operates (tap) the completion button I41 with his/her finger F1 on the work acceptance screen D3 displayed on the worker terminal 3A to report the completion of the work. This causes the worker terminal 3A to send a completion notification indicating that the task has been completed to the management device 2, and the display of the work acceptance screen D3 ends. At this time, the display of the worker terminal 3A transitions from the work acceptance screen D3 shown in FIG. 12B to the work instruction screen D1 shown in FIG. 12C.

In short, if the worker 91 accepts the second task while performing the first task, the first task being performed is interrupted. Therefore, the work instruction screen D1 shown in FIG. 12C is the same as the work instruction screen D1 when the first task being performed (here, "stocking products") is interrupted. However, in this case, it is not necessary to interrupt the first task being performed, and the display on the worker terminal 3 may return to the work selection screen D2 before the first task being performed (here, "stocking products") was interrupted.

(3.5) Request for Help Next, the transition of the screen displayed on the worker terminal 3 when making a request for help regarding the second task will be described with reference to FIGS. 13A to 13C.

In the following, an example will be described in which while worker 91A is performing the second task (operating the cash register), another task (second task) occurs related to operating the cash register, and a request for assistance is made to workers 91B and 91C who are performing the first task.

In this case, the worker 91A operates (tap) the request object I51 with the finger F1 on the work acceptance screen D3 (see FIG. 11B) displayed on the worker terminal 3A carried by the worker 91A. As a result, a support request is transmitted from the worker terminal 3A to the management device 2.

At this time, the display of the worker terminals 3B, 3C carried by the workers 91B, 91C transitions from the task selection screen D2 (see FIG. 9B) to the support request screen D4 shown in FIG. 13A. In other words, the screen display method according to this embodiment has a support request process. The support request process is a process in which, when an operation to select the request object I5 displayed on the task acceptance screen D3 of any of the worker terminals 3 is accepted, the display of the other worker terminal 3 is changed to the support request screen D4. The operation of the worker 91 here is not limited to tapping the request object I51, and may be, for example, an operation using a pointing device, voice input, gesture input, etc.

As shown in FIG. 13A, the support request screen D4 includes a request object I6 instead of the first region R1 and the second region R2. Therefore, the request object I6 occupies more than half of the support request screen D4. The configuration of the support request screen D4 is the same as that of the work instruction screen D1 except for the first region R1 and the second region R2. In other words, the support request screen D4 includes a menu display region R3 and a time display region R4 in addition to the request object I6.

The request object I6 is an object that notifies the content of the support request. In the example of FIG. 13A, the request object I6 notifies a request for support at the cash register. Specifically, the request object I6 contains the character string "19:18 Staff member A has requested help at the cash register."

The support request screen D4 includes a response button I61 and a non-response button I62 within a request object I6. The response button I61 displays the character string "Response", and the non-response button I62 displays the character string "Cannot respond". The response button I61 is operated (tapped) by the worker 91 when the worker 91 accepts the support request (response at the register), and the non-response button I62 is operated (tapped) by the worker 91 when the worker 91 rejects the support request (response at the register).

In this case, the worker 91B looks at the support request screen D4 displayed on the worker terminal 3B carried by the worker 91B, and operates (tap) the corresponding button I61 on the support request screen D4 shown in FIG. 13A with his/her finger F1 to accept the support request. This causes the worker terminal 3B to send an acceptance notification indicating that the support request has been accepted to the management device 2. At this time, the display on the worker terminal 3B transitions from the support request screen D4 shown in FIG. 13A to the work acceptance screen D3 shown in FIG. 13B.

The subsequent process is the same as the process described in "(3.4) Acceptance and Completion of the Second Task During Execution of the First Task". That is, after the completion of the task corresponding to the situation object I4 (here, "response to the cash register"), the worker 91B operates (tap) the completion button I41 with the finger F1 on the work acceptance screen D3 displayed on the worker terminal 3B to report the completion of the work. As a result, the worker terminal 3B transmits a completion notification indicating that the task has been completed to the management device 2, and the display of the work acceptance screen D3 ends. At this time, the display of the worker terminal 3B transitions from the work acceptance screen D3 shown in FIG. 13B to the work selection screen D2 shown in FIG. 13C. In short, when the worker 91 accepts the support request for the second task while executing the first task, the first task being executed is interrupted. Therefore, the work selection screen D2 shown in FIG. 13C is the same as the work selection screen D2 before the interruption of the first task being executed (here, "stocking the goods").

(3.6) Skip Processing Next, the transition of the screen displayed on the worker terminal 3 when skipping after accepting the first task will be described with reference to Figures 14A to 14C. In this case, the basic processing is the same as in "(3.1) Accepting and Completing the First Task", so the description will be omitted below as appropriate.

In the following, a case will be described in which, with the work instruction screen D1 as shown in Fig. 14A displayed, worker 91 accepts but then skips the task "change garbage bag" (first task) corresponding to the instruction timing of "11:00". Furthermore, as an example, it is assumed here that, of worker 91A performing stocking work, worker 91B performing cleaning work, and worker 91C serving customers as shown in Fig. 1, worker 91A accepts the work instruction.

In this case, the worker 91A looks at the work instruction screen D1 displayed on the worker terminal 3A carried by the worker 91A, and operates (tap) the first object I11 on the work instruction screen D1 shown in Fig. 14A with the finger F1 to accept the work instruction. As a result, an acceptance notification indicating that the work instruction has been accepted is sent from the worker terminal 3A to the management device 2. At this time, the display of the worker terminal 3A transitions from the work instruction screen D1 shown in Fig. 14A to the work selection screen D2 shown in Fig. 14B.

In this state, the worker 91 swipes the detailed object I3 horizontally (to the right, for example) on the work selection screen D2 without operating either the complete button I31 or the cancel button I32 in the detailed object I3. This causes the worker terminal 3A to send a skip notification indicating that the task is to be skipped to the management device 2, and the display of the work selection screen D2 ends. At this time, the display of the worker terminal 3A transitions from the work selection screen D2 shown in FIG. 14B to the work instruction screen D1 shown in FIG. 14C.

Here, as a result of the skip notification, the task accepted by worker 91A (here, "change garbage bag") is in a skipped state, not an incomplete, accepted, or completed state. The skipped state is the state of a task that indicates that the worker 91 has determined that there is no need to perform it. Therefore, unlike an incomplete task, for a skipped task, the corresponding first object I1 is deleted from the first area R1 of the work instruction screen D1. Therefore, in the work instruction screen D1 shown in Figure 14C, the first object I11 corresponding to "change garbage bag" that was included in the work instruction screen D1 of Figure 14A has been deleted.

Furthermore, unlike tasks in the accepted or completed states, tasks in the skipped state are not performed by any of the workers 91, and so are not recorded as achievements for the workers 91. In the achievement information, the skipped task is recorded as a history in the "skipped state." In other words, it is possible to avoid having achievements for the skipped task (here, "changing garbage bags") recorded for the worker 91A.

That is, the screen display method according to this embodiment further includes a skip process that sets the state of the selected task to an incomplete state. When an operation of the worker 91 indicating that the selected task is to be skipped is received on the work selection screen D2, the skip process is executed. The operation of the worker 91 here is not limited to a tap on the first object I1, and may be, for example, an operation using a pointing device, a voice input, a gesture input, or the like.

(3.7) Display Task Switching Function Next, transition of the screen displayed on the worker terminal 3 when switching the first object I1 displayed in the first area R1 will be described with reference to FIGS. 15A to 15C.

In the following, it is assumed that when a work instruction screen D1 such as that shown in FIG. 15A is displayed, a first object I1 corresponding to a future task (first task) or a first object I1 corresponding to a past task (first task) is displayed in the first area R1.

First, when checking future tasks, the worker 91 swipes any of the first objects I1 in one horizontal direction (to the right, for example) on the work instruction screen D1 shown in FIG. 15A. This causes the display of the worker terminal 3 to transition from the work instruction screen D1 shown in FIG. 15A to the work instruction screen D1 shown in FIG. 15B. On the work instruction screen D1 in FIG. 15B, the first object I1 corresponding to the future task (first task) is displayed in the first region R1. The first object I1 displayed at this time corresponds to the task (first task) that is in an uncompleted state. This allows the worker 91 to check the next 10 tasks from the present along with the display of the work instruction screen D1 shown in FIG. 15A.

On the other hand, when checking a past task, in the work instruction screen D1 shown in FIG. 15A, the worker 91 swipes any of the first objects I1 to the other side of the horizontal direction of the work instruction screen D1 (for example, to the left). As a result, the display of the worker terminal 3 transitions from the work instruction screen D1 shown in FIG. 15A to the work instruction screen D1 shown in FIG. 15C. In the work instruction screen D1 of FIG. 15C, the first object I1 corresponding to the past task (first task) is displayed in the first area R1. The first object I1 displayed at this time corresponds to the task (first task) in an uncompleted state. In other words, the first object I1 that is erased from the first area R1 at the time of the erasure timing by the time-limited erasure process is displayed in the first area R1 of the work instruction screen D1 of FIG. 15C. Furthermore, the task (first task) that occurs suddenly is not displayed in the first area R1 of the work instruction screen D1 of FIG. 15C. As a result, the worker 91 can check the past task that is in an uncompleted state.

In other words, the screen display method according to the present embodiment further includes a change process for changing the first object I1 displayed in the first region R1 by performing a predetermined operation on the work instruction screen D1. The operation by the worker 91 here is not limited to swiping the first object I1, and may be, for example, an operation using a pointing device, a voice input, a gesture input, or the like.

(4) Modifications The first embodiment is merely one of various embodiments of the present disclosure. Various modifications of the first embodiment are possible depending on the design and the like, as long as the object of the present disclosure can be achieved. The same function as the screen display method according to the first embodiment may be embodied in the screen display system 100, a computer program, or a non-transitory recording medium on which the computer program is recorded. The program according to one aspect is a program for causing one or more processors to execute the screen display method according to the first embodiment. The screen display system 100 according to one aspect includes an information acquisition unit 341 and a display processing unit 342. The information acquisition unit 341 acquires acquired information. The acquired information is information on work schedule information that represents a correspondence relationship between a first task, which is the work of the worker 91, and an instruction timing of the first task. The display processing unit 342 is a process for displaying a work instruction screen D1 on the worker terminal 3 based on the acquired information. The work instruction screen D1 is a screen for instructing the worker 91 to perform work. Here, the work instruction screen D1 includes a first region R1 and a second region R2. The first area R1 is an area for displaying a first object I1 corresponding to a first task included in the work schedule information, and the second area R2 is an area for displaying a second object I2 corresponding to a second task, which is work of the worker 91 and is different from the first task.

In addition, functions similar to those of the store support system 10 may be embodied in a store support method, a computer program, or a non-transitory recording medium on which a computer program is recorded. The store support method according to one embodiment includes an instruction process, a detection process, and a performance output process. The instruction process is a process of instructing each of the multiple workers 91 to perform at least one of a regular task and an irregular task for a plurality of tasks that are work performed by the multiple workers 91 in the store 9. The regular task is generated based on work schedule information. The work schedule information is information that represents the correspondence between each of the multiple tasks and the instruction timing. The irregular task occurs irregularly. The detection process is a process of detecting the execution of at least one task of the multiple tasks by a worker 91 instructed by the instruction process among the multiple workers 91. The performance output process is a process of generating performance information that represents the execution status of the multiple tasks by each of the multiple workers 91 based on the detection result of the detection process, and outputting the performance information. The program according to one embodiment is a program for causing one or more processors to execute the above store support method.

Below, we list some variations of the first embodiment. The variations described below can be combined as appropriate.

(4.1) First Modification A store support system 10A according to a first modification of the first embodiment differs from the store support system 10 according to the first embodiment in that an instruction unit 24 that instructs each worker 91 on a task is provided outside the store 9, as shown in Fig. 16. Hereinafter, components similar to those in the first embodiment will be denoted by the same reference numerals and descriptions thereof will be omitted as appropriate.

That is, in the store support system 10A, a management device 2 including an instruction unit 24 is provided outside the store 9. Like the server device 1, the management device 2 is mainly composed of a computer system having one or more processors and memory, and is connected to a network 4 such as the Internet. Like the server device 1, the management device 2 is installed, for example, in a service company that provides the store support system 10 or in an operating company of the store 9. Like the server device 1, the management device 2 preferably uses a PaaS environment, which is a public cloud environment without management of the OS, runtime, and middleware. The store support system 10A according to this modified example has a second communication unit 21, a processing unit 22, an instruction unit 24, and a memory unit 25.

The store support system 10A according to this modified example also includes a sensor control device 29. The sensor control device 29 is installed in the store 9. The sensor control device 29 is mainly composed of a computer system having one or more processors and memories. The sensor control device 29 is connected to the network 4 via a router 5 installed in the store 9. The sensor control device 29 can, for example, control a plurality of sensors 7A, 7B, 7C, a detection unit 27, and an occurrence detection unit 28 to perform predetermined signal processing or the like on the respective detection results and output them to the server device 1, the management device 2, the worker terminal 3, etc.

As shown in FIG. 16, the sensor control device 29 has a fourth communication unit 291, a processing unit 292, and an interface 293. The fourth communication unit 291 corresponds to the second communication unit 21 (see FIG. 2) of the first embodiment, and is a communication module that communicates bidirectionally with, for example, the server device 1, the management device 2, and the worker terminal 3. The processing unit 292 corresponds to the processing unit 22 (see FIG. 2) of the first embodiment, and transmits and receives various information (data) with, for example, the server device 1 via the fourth communication unit 291. The processing unit 292 is also connected to the monitor 26, and controls the monitor 26 so that various information is displayed on the monitor 26. The interface 293 corresponds to the interface 23 (see FIG. 2) of the first embodiment, and is connected to the multiple sensors 7A, 7B, 7C, the detection unit 27, and the occurrence detection unit 28.

In this configuration, in the store support system 10A according to the first modified example of the first embodiment, the management device 2 provided outside the store 9 generates and outputs work instructions at the instruction unit 24, and instructs each worker 91 to perform a task by the work instruction. The instruction unit 24 generates work instructions according to the work schedule information received from the server device 1. The work instructions generated according to the work schedule information are work instructions for a first task that is a periodic task or a semi-periodic task. Furthermore, in this modified example, the instruction unit 24 generates work instructions according to a work order received from the server device 1. The work instructions generated according to the work order are work instructions for a second task that is a task other than a semi-periodic task among non-periodic tasks. Therefore, the instruction unit 24 generates work instructions to instruct the execution of both the first task and the second task. The instruction unit 24 outputs the work instructions by transmitting the generated work instructions from the second communication unit 21 to the worker terminal 3.

In addition, in this modified example, the detection unit 27 is connected to the network 4 via the sensor control device 29, and therefore the detection result of the detection unit 27 is transmitted to the server device 1 or the management device 2 via the sensor control device 29. Similarly, the occurrence detection unit 28 is connected to the network 4 via the sensor control device 29, and therefore the detection result of the occurrence detection unit 28 is transmitted to the server device 1 or the management device 2 via the sensor control device 29.

However, it is not essential that the detection unit 27 is connected to the sensor control device 29, and the detection unit 27 may transmit the detection result to the server device 1 or the management device 2 without going through the sensor control device 29. As an example of a configuration for transmitting the detection result to the server device 1 or the management device 2 without going through the sensor control device 29, the detection unit 27 capable of communicating with the worker terminal 3 can be considered. In this case, the detection unit 27 functions as a transmitter that outputs (transmits) a wireless signal to the worker terminal 3, and transmits a wireless signal to the worker terminal 3 in the work area A1 (see FIG. 8A). In other words, when a worker 91 enters the work area A1, the worker terminal 3 carried by the worker 91 receives a wireless signal from the detection unit 27. In this case, the execution of a specific task by the worker 91 can be detected on the worker terminal 3 side. In other words, the detection unit 27 functions as a "detection unit" for detecting the execution of at least one task among the multiple workers 91 by the worker 91 assigned by the assignment unit 17, together with the worker terminal 3, for at least one task among the multiple workers 91. In this case, the worker terminal 3 transmits the detection result to the server device 1 or the management device 2 via the network 4 .

(4.2) Other Modifications The store support system 10 in the present disclosure includes a computer system, for example, in the server device 1, the management device 2, and the worker terminal 3. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system, thereby realizing the functions of the store support system 10 in the present disclosure. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be recorded and provided in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuits such as IC or LSI here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of an LSI, or a logic device that allows reconfiguration of the connection relationship within the LSI or reconfiguration of the circuit partition within the LSI, can also be adopted as a processor. The electronic circuits may be integrated into one chip, or may be distributed among multiple chips. The chips may be integrated into one device, or may be distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

In addition, it is not essential for the store support system 10 that multiple functions are concentrated in one housing, and the components of the store support system 10 may be distributed across multiple housings. Furthermore, at least some of the functions of the store support system 10, for example, the functions of the server device 1, may be realized by the cloud (cloud computing) or the like. Similarly, for the screen display system 100, it is not essential for the screen display system 100 that multiple functions are concentrated in one housing, and the components of the screen display system 100 may be distributed across multiple housings.

On the contrary, in the first embodiment, at least some of the functions of the store support system 10 distributed among multiple devices may be consolidated in one housing. For example, some of the functions of the store support system 10 distributed among the server device 1 and the management device 2 may all be consolidated into the management device 2, in which case the server device 1 may be omitted. Some of the functions of the store support system 10 distributed among the server device 1 and the management device 2 may all be consolidated into the server device 1, in which case the management device 2 may be omitted. In other words, it is not essential for the store support system 10 to have the server device 1, the management device 2, and the worker terminal 3, and at least one of the server device 1, the management device 2, and the worker terminal 3 may be omitted as appropriate. For example, when the management device 2 is omitted, the work instruction is generated by the server device 1 and transmitted from the server device 1 to the worker terminal 3.

Furthermore, techniques such as machine learning may be used for some of the processes of the store support system 10, such as the process of changing task priorities and the process of predicting workload. In particular, it is preferable to use techniques such as machine learning in determining what kind of work schedule information should be generated under what circumstances to lead to increased sales at the store 9.

Furthermore, it is not a required configuration of the store support system 10 that the schedule generation unit 13 generates work schedule information based on at least the task information and store information acquired by the acquisition unit 12. In other words, the schedule generation unit 13 only needs to generate work schedule information that indicates the correspondence between each of the multiple tasks and the instruction timing for the multiple tasks, and there is no particular limitation on the information based on which the work schedule information is generated.

Furthermore, the detection unit 27 need only be configured to detect the execution of at least one of the multiple tasks by one of the multiple workers 91 who has been assigned by the assignment unit 17, and is not limited to being a receiver that receives a wireless signal from the transmitter 911. For example, the detection unit 27 may include a sensor such as an image sensor (camera), an optical sensor, or a contact sensor. Furthermore, the detection unit 27 may detect, for example, that the worker 91 has logged into the POS system. In this case, the detection unit 27 may detect that the worker 91, who has been assigned the task of operating the cash register, has logged into the POS system, thereby detecting that the worker 91 has operated the cash register.

In addition, the transmitter 911 that outputs a wireless signal to the detection unit 27 consisting of a receiver is not limited to a dedicated transmitter 911 such as a beacon or electronic tag, but may be, for example, a worker terminal 3.

Furthermore, it is sufficient for the performance output unit 18 to generate performance information using at least the detection results of the detection unit 27, and it is not essential that the performance output unit 18 use the work schedule information, the worker information, and the work status of each worker 91 in generating the performance information. For example, the performance output unit 18 may generate performance information based on one or two pieces of information among the work schedule information, the worker information, and the work status of each worker 91 in addition to the detection results of the detection unit 27, or may generate performance information based only on the detection results of the detection unit 27.

In addition, the use of the store support system 10 is not limited to convenience stores, and the store support system 10 may be installed in a store 9 other than a convenience store. Furthermore, the screen display method according to embodiment 1 may be used in places other than the store 9. For example, the screen display method may be applied to instruct various tasks in a factory, office, school, etc.

In addition, in the first embodiment, tasks involving customer service, such as cash register operations, age verification, and serving fast food, are particularly urgent and are therefore excluded from the tasks in the work schedule information (i.e., the first tasks), but this is not limiting and these tasks may be included in the first tasks. In this case, it is preferable to set the highest priority for these urgent tasks.

In addition, in embodiment 1, an example is shown in which the work instructions generated by the instruction unit 24 of the management device 2 are transmitted directly from the management device 2 to the worker terminal 3, but this example is not limited to this, and for example, the work instructions may be transmitted indirectly from the management device 2 to the worker terminal 3 via the server device 1.

In addition, the age verification processing function is not a required component of the store support system 10, and the age verification processing function may be omitted.

Furthermore, the allocation unit 17 is not a required component of the store support system 10, and the allocation unit 17 may be omitted.

In addition, the management device 2 is not limited to a configuration in which work instructions are transmitted by multicast, and may, for example, transmit work instructions sequentially to multiple worker terminals 3A, 3B, and 3C by unicast, or may transmit work instructions by broadcast.

The management device 2 may be configured to be able to arbitrarily select a worker terminal 3 to be excluded from among the multiple worker terminals 3A, 3B, 3C as a destination of a work instruction. In this case, for example, a worker terminal 3 carried by a worker 91 who is unable to perform a task, such as a worker 91 on a break, may be temporarily excluded from the destination of a work instruction. In addition, the multiple worker terminals 3A, 3B, 3C may be used for communication between the multiple workers 91A, 91B, 91C by directly communicating between the multiple worker terminals 3A, 3B, 3C.

In addition, the worker terminal 3 and the manager terminal 8 are not limited to smartphones, but may be, for example, tablet terminals, personal computers, or wearable terminals such as wristwatches or glasses. Furthermore, the worker terminal 3 and the manager terminal 8 are not limited to general-purpose terminals, but may be terminals dedicated to the store support system 10.

In addition, the worker terminal 3 is not limited to being worn on the upper arm of the left arm of the worker 91, but may be worn on the right arm or on a part other than the upper arm, for example. Furthermore, the worker terminal 3 may be worn directly or indirectly on a part other than the arm of the worker 91, for example, by hanging it from the neck, by wearing it on a belt, or by wearing it on clothing like a badge.

In addition, for example, the communication method between the management device 2 and the worker terminal 3 is not limited to wireless communication using radio waves as a medium, but may be, for example, optical wireless communication using light as a medium, or a communication method that includes wired communication in part, etc. Similarly, the communication method between the server device 1 and the worker terminal 3 is not limited to wireless communication using radio waves as a medium, but may be, for example, optical wireless communication using light as a medium, or a communication method that includes wired communication in part, etc. The communication method between the server device 1 and the management device 2 is not limited to wired communication, but may be, for example, wireless communication using radio waves as a medium, or optical wireless communication using light as a medium, etc.

(Embodiment 2)
The store support system 10 according to this embodiment differs from the store support system 10 according to the first embodiment in that a group object G1 corresponding to a plurality of first objects I1 is applied, as shown in Figures 17A and 17B. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted as appropriate.

17A and 17B show specific examples of screens displayed on the display unit 32, where the dashed dotted lines and reference symbols indicating areas are shown merely for explanatory purposes, and in reality, these dashed dotted lines and reference symbols are not displayed on the display unit 32. Also, in Fig. 17A and 17B, the finger F1 of a person (worker 91) operating (tapping, swiping, dragging, etc.) an object such as a button on each screen displayed on the display unit 32, and its movement are shown by an imaginary line (two-dot dashed line).

In this embodiment, as in embodiment 1, it is assumed that a plurality of first objects I1 are displayed in the first region R1. Here, the plurality of first objects I1 correspond to one group object G1. In other words, the group object G1 and the plurality of first objects I1 are in a hierarchical structure in which they are in a superior-subordinate relationship, and the plurality of first objects I1 are linked to one group object G1 under (below). In addition to displaying the plurality of first objects I1 in the first region R1 in the work instruction screen D1, it is also possible to display a group object G1 that is superior to the plurality of first objects I1.

In this embodiment, as an example, as shown in FIG. 17A, multiple (here, three) group objects G11 to G13 are displayed in the first region R1. When no particular distinction is made between the three group objects G11 to G13, each of the three group objects G11 to G13 is also simply referred to as a "group object G1." As an example in FIG. 17A, group object G11 corresponds to cleaning tasks, group object G12 corresponds to replenishment tasks, and group object G13 corresponds to other tasks. For example, cleaning tasks include tasks (first tasks) such as cleaning around the store, changing garbage bags, and cleaning toilets.

On the work instruction screen D1 shown in Fig. 17A, the worker 91, for example, operates (tap) the group object G11 with the finger F1. As a result, the display of the worker terminal 3 transitions from the work instruction screen D1 shown in Fig. 17A to the work instruction screen D1 shown in Fig. 17B. On the work instruction screen D1 in Fig. 17B, a plurality of first objects I11 to I15 corresponding to the group object G11 are displayed in the first region R1. In other words, when the group object G1 is selected on the work instruction screen D1, the selected group object G1 is expanded into a plurality of first objects I11 to I15 within the first region R1.

That is, in the screen display method according to this embodiment, a plurality of first objects I1 are displayed in the first region R1. The group object G1 corresponds to the plurality of first objects I1. In the screen display method, when an operation to select the group object G1 is received while the group object G1 is displayed in the first region R1, the plurality of first objects I1 corresponding to the selected group object G1 are displayed in the first region R1.

In this embodiment, the operations from acceptance to completion of the first task may be replaced with the operations described in "(3.1) Acceptance and Completion of the First Task" by the operations described below.

That is, when accepting a work instruction, the worker 91 may operate (tap) the group object G1 of the first object I1 on the work instruction screen D1 shown in Fig. 17A, and an acceptance notification may be output from the worker terminal 3. In short, the worker 91 can accept the task (first task) on the work instruction screen D1 in Fig. 17B without operating the first object I1, which is subordinate to the group object G1. This can reduce the number of operations required by the worker 91 when accepting a task.

In this case, it is preferable that the work instruction screen D1 on which the multiple first objects I1 are displayed includes an individual completion button and/or a collective completion button object, as shown in FIG. 17B. A plurality of individual completion buttons are provided in one-to-one correspondence with the multiple first objects I1, and one collective completion button is provided for each of the multiple first objects I1. The individual completion button is operated (tapped) by the worker 91 when a corresponding first task is completed, and the collective completion button is operated (tapped) by the worker 91 when a corresponding multiple first tasks are completed. In other words, when only one first task of the multiple first tasks is completed, the worker 91 operates (tap) the individual completion button, and the worker terminal 3 transmits a completion notification indicating that the first task has been completed. On the other hand, when all of the multiple first tasks are completed, the worker 91 operates (tap) the collective completion button, and the worker terminal 3 transmits a completion notification indicating that all of the multiple first tasks have been completed. This makes it possible to reduce the number of operations required for the worker 91 to report the completion of a task.

The various configurations (including modified examples) described in embodiment 2 can be adopted in appropriate combination with the various configurations (including modified examples) described in embodiment 1.

(summary)
As described above, the screen display method according to the first aspect includes an acquisition process and a display process. The acquisition process is a process of acquiring acquired information. The acquired information is information on work schedule information that represents a correspondence between a first task, which is work of the worker (91), and an instruction timing of the first task. The display process is a process of displaying a work instruction screen (D1) on the worker terminal (3) based on the acquired information acquired in the acquisition process. The work instruction screen (D1) is a screen for instructing the worker (91) to perform work. The work instruction screen (D1) includes a first area (R1) and a second area (R2). The first area (R1) is an area that displays a first object (I1) corresponding to the first task included in the work schedule information. The second area (R2) is an area that displays a second object (I2) corresponding to a second task, which is work of the worker (91) and is different from the first task.

According to this aspect, the first task included in the work schedule information and the second task, which is the work of the worker (91) and is different from the first task, can be displayed in a listable form on the work instruction screen (D1). Therefore, for example, by making a work such as cash register operation, which is not included in the work schedule information, i.e., not associated with the instruction timing, the second task can be instructed to the worker (91) on the work instruction screen (D1) together with the first task. Therefore, the worker (91) can easily recognize the second task, which is not included in the work schedule information, as work to be performed by him/herself in parallel with the first task included in the work schedule information. As a result, the screen display method makes it easier for the worker (91) to perform both the work included in the work schedule information and the work not included in the work schedule information, and it is possible to give more appropriate work instructions.

The screen display method according to the second aspect further includes a first transition process in the first aspect. The first transition process is a process of changing the display of the worker terminal (3) from a work instruction screen (D1) to a work selection screen (D2) when an operation to select a first task related to a first object (I1) displayed in a first area (R1) is accepted.

According to this aspect, an operation to select a first task related to a first object (I1) can be accepted on the work instruction screen (D1).

In the screen display method according to the third aspect, in the second aspect, the work schedule information includes a plurality of first tasks. In the first transition process, when an operation to select a first object (I1) corresponding to a selected task consisting of one of the plurality of first tasks is received on the work instruction screen (D1), a work selection screen (D2) is displayed. The work selection screen (D2) includes a detailed object (I3) related to the selected task and having a display area larger than that of the first object (I1).

According to this aspect, by selecting a first task related to a first object (I1) on the work instruction screen (D1), a detailed object (I3) related to the selected task can be displayed.

The screen display method according to the fourth aspect further includes a completion process for setting the status of the selected task to a completed state in the third aspect. When an operation by a worker (91) indicating that the selected task has been completed is received on the work selection screen (D2), the completion process is executed.

According to this aspect, after selecting the first task, the worker (91) can perform an operation to execute the completion process without changing the screen from the task selection screen (D2).

The screen display method according to the fifth aspect further includes a skip process for setting the status of the selected task to an incomplete state in the third or fourth aspect. When an operation by a worker (91) indicating that the selected task is to be skipped is received on the work selection screen (D2), the skip process is executed.

According to this aspect, after selecting the first task, the worker (91) can perform an operation to execute the skip process without changing the screen from the task selection screen (D2).

The screen display method according to the sixth aspect is any one of the first to fifth aspects, and further includes a second transition process. The second transition process is a process of changing the display of the worker terminal (3) from the work instruction screen (D1) to the work acceptance screen (D3) when an operation to select a second task related to a second object (I2) displayed in the second area (R2) is accepted.

According to this aspect, an operation to select a second task related to a second object (I2) can be accepted on the work instruction screen (D1).

In the screen display method of the seventh aspect, in any of the first to sixth aspects, the work related to the second task includes at least one of work related to accounting, work related to cooking, and work related to customer service.

According to this embodiment, the worker (91) can be instructed on the second task, which has a relatively high level of urgency, together with the first task.

The screen display method according to the eighth aspect is any one of the first to seventh aspects, and further includes a change process. The change process is a process of changing the first object (I1) displayed in the first area (R1) by performing a predetermined operation on the work instruction screen (D1).

According to this aspect, the first object (I1) displayed in the first area (R1) can be changed by a specified operation.

The screen display method according to the ninth aspect is any one of the first to eighth aspects, and further includes a sudden display process. The sudden display process is a process of displaying a first object (I1) corresponding to a first task in a first area (R1) at a timing prior to an instruction timing associated with the first task in the work schedule information.

According to this aspect, even if the first task occurs suddenly, the first task can be instructed to be carried out ahead of schedule to the worker (91).

In a screen display method according to a tenth aspect, in any one of the first to ninth aspects, a plurality of first objects (I1) are displayed in a first area (R1). The plurality of first objects (I1) are arranged in an order according to at least one of the priority and the instruction timing of the corresponding first task.

According to this aspect, for example, a first task having a high priority or an early instruction timing is easily recognized by the worker (91).

In the screen display method relating to the 11th aspect, in any of the first to tenth aspects, the display manner of the first object (I1) differs depending on the priority of the corresponding first task.

According to this aspect, for example, a first task having a high or low priority can be easily recognized by the worker (91).

The screen display method according to the twelfth aspect is any one of the first to eleventh aspects, and further includes an erasure process. The erasure process is a process of erasing a first object (I1) for which the state of the corresponding first task has become an accepted state or a completed state from the first area (R1).

According to this aspect, by erasing the first object (I1) corresponding to the first task for which instructions are no longer required, the first object (I1) corresponding to the first task for which instructions are required becomes easier for the worker (91) to recognize.

The screen display method according to the thirteenth aspect is any one of the first to twelfth aspects, and further includes a time-limited erasure process. The time-limited erasure process is a process for erasing a first object (I1) from a first area (R1) when an erasure timing determined by at least one of the priority of the corresponding first task and the instruction timing has come.

According to this aspect, for example, a first object (I1) whose corresponding first task has a low priority or for which a long time has passed since the instruction timing can be appropriately erased.

In a screen display method according to a fourteenth aspect, in any one of the first to thirteenth aspects, a plurality of first objects (I1) are displayed in a first area (R1). A group object (G1) corresponds to the plurality of first objects (I1). When an operation to select a group object (G1) is received while the group object (G1) is displayed in the first area (R1), a plurality of first objects (I1) corresponding to the selected group object (G1) are displayed in the first area (R1).

According to this aspect, multiple first objects (I1) are bundled together into a group object (G1), making it easier to reach the desired first object (I1).

The program relating to the fifteenth aspect is a program for causing one or more processors to execute a screen display method relating to any one of the first to fourteenth aspects.

According to this aspect, it becomes easier for the worker (91) to perform both tasks that are included in the work schedule information and tasks that are not included in the work schedule information, and it is possible to issue more appropriate work instructions.

The screen display system (100) according to the sixteenth aspect includes an information acquisition unit (341) and a display processing unit (342). The information acquisition unit (341) acquires acquired information. The acquired information is information about work schedule information that represents a correspondence between a first task, which is the work of a worker (91), and the instruction timing of the first task. The display processing unit (342) displays a work instruction screen (D1) on the worker terminal (3) based on the acquired information. The work instruction screen (D1) is a screen for instructing the worker (91) to perform work. The work instruction screen (D1) includes a first area (R1) and a second area (R2). The first area (R1) is an area that displays a first object (I1) corresponding to the first task included in the work schedule information. The second area (R2) is an area that displays a second object (I2) corresponding to a second task, which is the work of the worker (91) and is different from the first task.

According to this aspect, it becomes easier for the worker (91) to perform both tasks that are included in the work schedule information and tasks that are not included in the work schedule information, and it is possible to issue more appropriate work instructions.

Not limited to the above aspects, various aspects (including modified examples) of the screen display method according to embodiment 1 and embodiment 2 can be embodied in a screen display system (100), a program, and a non-transitory recording medium having the program recorded thereon.

The configurations relating to aspects 2 to 14 are not essential to the screen display method and may be omitted as appropriate.
