[0013] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that each of the embodiments described below represents a specific example of the present disclosure. Therefore, the components, the arrangement positions and connection forms of the components, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Furthermore, among the components in the following embodiments, components not recited in independent claims will be described as optional components.

[0014] Furthermore, each drawing is a schematic diagram and is not necessarily an exact illustration. In each drawing, the same reference numerals are used to denote substantially the same components, and redundant explanations may be omitted or simplified.

[0015] FIG. 1 is a functional configuration diagram of a work support device 1 according to the present disclosure. FIG. 2 is a diagram illustrating a hardware configuration of the work support device 1 according to the present disclosure. FIG. 3 is a diagram illustrating an example of a work support system according to the present disclosure. In FIG. 1, a worker acquisition unit 2 acquires information about the worker who will be performing the work. The information about the worker includes information about the worker that should be considered when determining where to place an item, such as an ID that identifies the worker, the worker's dominant hand, the worker's height, and the worker's gender. Here, the items include items related to the work, such as the product to be worked on, materials such as packaging containers and tape, and tools such as scissors.

[0016] The work content acquisition unit 3 acquires information about the content of the work to be performed. The information about the content of the work includes, for example, information about the type of work, such as individual packaging, packing, or inspection, the size of the products to be handled, such as large, medium, or small, the type of products to be handled, such as precision equipment or general equipment, and the work content to be considered when determining the storage location of items, such as tools used in the work.

[0017] The storage location acquisition unit 4 acquires information about the items used in the work and their storage locations based on information about the worker and information about the work content.

[0018] The information about the item includes information about the type of item used in the work, such as tape, scissors, etc. The information about the location includes information about the position on the workbench where the item used in the work was placed, for example.

[0019] Information on items and their storage locations is obtained, for example, from a database, including the most recent information on items and their storage locations used in similar tasks performed in the past. Similar tasks include tasks that are expected to result in roughly the same item storage locations, such as the same type of tasks performed by the same worker or the same type of tasks performed by workers with the same dominant hand. If the existence of similar tasks cannot be confirmed in the database, a pre-constructed machine learning model for determining routine tasks can be used to determine whether the task is similar to a routine task based on video footage taken after the task has started. If the task is determined to be similar to a certain routine task, information on the items used in the routine task and their storage locations may be obtained.

[0020] The display unit displays to the worker information about the items to be used in the work and their locations. For example, the display is performed by projecting an image of the type of item and its location onto the work table from a projector 20 installed above the work table. The image is projected at a fixed position for each item, with the display mode (shape, color, etc.) changed to indicate the type of item. Alternatively, instead of using a projector, a method of displaying the type of item and its location on the worker terminal 21 using a floor plan may be used.

[0021] In addition, if the display of information about the item and its location is temporary, such as immediately before work begins, there is a possibility that the location of the item to be used may change during work if the item is scissors, a cutter, etc. Therefore, the information about the item and its location may be displayed at all times, or the information about the item and its location may be re-displayed when it is detected that the location of the item has shifted by a specified distance (for example, 10 cm) or more from the original location.

[0022] The load calculation unit 6 calculates the workload for each item based on a video of the worker working. The workload may be calculated by, for example, inputting the video into the AI ​​analysis server 23 to obtain the location of each item during work, the location of the worker, and the number of times each item was used, and taking into account the weight of each item, the distance traveled, and the number of times the item was moved (used).

[0023] The workload may be calculated, for example, using the following formula: [Number 1] Rating score S = (distance from worker to item cm x coefficient f1) x (number of times item is used x coefficient f2) x (weight of item g x coefficient f3)

[0024] The coefficients f1, f2, and f3 may be set arbitrarily depending on the degree to which the distance from the worker to the item (cm), the number of times of use (times), and the weight of the item (g) contribute to the workload. Then, by calculating a rating score S for each item using Equation 1, the workload on the worker caused by using each item can be numerically evaluated.

[0025] The item identification unit 7 identifies items whose placement should be improved. For example, the rating score calculated by the above formula 1 can be reduced by placing the item closer to the worker. Therefore, the item identification unit identifies items whose rating scores are higher than other items as items that should be placed closer to the worker. For example, since the rating score increases as the number of times the item is used increases, the target item is identified by determining whether the score exceeds a predetermined threshold. Alternatively, the target item may be identified based on its relatively higher rating score than other items, for example, when one score is higher than the other score by a predetermined value or more, or when one score is more than twice the other score.

[0026] The notification unit 8 notifies the worker that the item identified by the item identification unit 7 should be placed near the worker. The notification may be, for example, a method of displaying a message such as "(Item name) is used frequently. Moving it closer to you is expected to improve work efficiency" on the worker terminal.

[0027] The notification may also be made by, for example, projecting the location of the item to be moved onto the workbench from a projector installed above the workbench. In this case, it is preferable to project an image indicating the direction of movement corresponding to the item on the workbench.

[0028] With the above configuration, workers can easily grasp the items to be used in the work and their locations on the workbench before starting the work, and can perform the work efficiently by placing the items in those locations.

[0029] Furthermore, workers can obtain improvement suggestions that will reduce their workload based on the results of using items in work, and can perform work more efficiently by changing the location of items while working.

[0030] Next, in FIG. 2, a memory 12, a storage 13, a drive 14, a user interface 15, and a communication device 16 are connected to a processor 11 of the work support device 1 via a bus.

[0031] The processor 11 executes the work support program recorded in the storage 13 while temporarily recording data in the memory 12. The storage 13 is a storage device such as an SSD, and stores an operating system, the work support program, video, various data, etc. The work support program performs its functions in cooperation with the operating system.

[0032] The drive 14 is an optical drive, a USB memory, or the like, and is used for loading programs, transferring data, and the like.

[0033] The user interface 15 is a device through which a user (administrator) inputs necessary information and displays the results of calculations, and specifically includes a display, keyboard, mouse, touch panel, and the like.

[0034] The communication device 16 is a device for connecting to a network such as the Internet or a LAN. Although only the work assistance device 1 is described here, as shown in Fig. 3, the work assistance device 1 can be configured as a server device (on-premise or cloud) connected to a network with a projector 20, a worker terminal 21, a camera 22, an AI analysis server 23, a database 24, etc.

[0035] In the work support system of Fig. 3, the projector 20 is for displaying the storage location determined by the work support device 1. The worker terminal 21 is for the worker to input necessary information and for acquiring and displaying the storage location from the work support device 1. The camera 22 is for capturing images of the worker working. The AI ​​analysis server 23 is for performing analysis such as work breakdown based on the images captured by the camera 22.

[0036] In analyzing work breakdown and the like, the AI ​​analysis server 23 performs object recognition to recognize workers and items (parts, work tools, etc.) as objects from the video to be analyzed, as well as task recognition (task estimation) to recognize the type of work. Task recognition recognizes the work content from the worker's movements and the types of items the worker has come into contact with. In addition, the type of item used for each task (tool name, weight), the distance between the item and the worker, the number of times it has been used, etc. can be obtained as recognition result information. In the object recognition and task recognition processes, an object task recognition model (machine learning model) constructed using machine learning such as deep learning can be used.

[0037] The database 24 is for storing various data, and may be configured as an external device connected to the task support device 1, or may be configured as a storage device built into the task support device 1.

[0038] In the above example, the work support device 1, the AI ​​analysis server 23, and the database 24 are configured as separate devices to form a system, but these may also be configured as an integrated unit in the same information processing device.

[0039] 4 is a flowchart showing the operation of the work support device 1 of the present disclosure to display the location of items to be used in work when a worker starts work. First, the processor 11 of the work support device 1 (hereinafter sometimes simply referred to as the "work support device") acquires information about the worker and the work content (step S1).

[0040] 5 shows an example of a screen 30 for inputting and setting information about a worker. The worker inputs a worker ID in a worker ID input area 31. The work support device 1 searches for information about the worker stored in the database 24 based on the input worker ID, and if matching information is found, automatically inputs information about the worker into a dominant hand input area 32, a height input area 33, and a gender input area 34.

[0041] If the database 24 does not contain information about the contractor (for example, if the worker is working for the first time), the worker enters his / her own information in the dominant hand input area 32, height input area 33, and gender input area 34.

[0042] FIG. 6 shows an example of a screen 40 for inputting and setting information about the work content. The worker selects the work content from a list in a work content selection area 41. The worker also selects the size of the product to be handled in a product size input area 42. The worker also selects the type of product to be handled in a product type selection area 43. The worker also selects the tool to be used for the work in a tool selection area 44. The worker may select the tool to be used from a list, or the work support device 1 may retrieve tools used in similar work in the past from the database 24 based on the input work content, product size, and product type, and display them as defaults so that the worker can change them as appropriate.

[0043] Returning to the flowchart in Fig. 4, the work support device 1 then searches the database 24 to see if a similar work has been performed in the past, based on the input information about the worker and the information about the work content (step S2). Similar work refers to work that is expected to involve almost the same item placement, such as work with the same worker ID, work content, product size, and product type, or work with the same work content, product size, and product type and the same worker's dominant hand and gender. If a similar work has been performed in the past (yes in step S2), the work support device 1 acquires information about the items used and their placement locations, and displays this information on the workbench using the projector 20 or on the worker terminal 21 (step S3).

[0044] 7 is an example of a table of the placement locations of each item acquired by the work support device 1. The table records information such as the tool name, the center coordinates (x, y) where the tool was placed, and the orientation (angle) at which the tool was placed. The work support device 1 may directly display an image of the placement location of each item on the worker terminal 21 based on the information in this table, or may project and display an image of the placement location of each item onto the work table from a projector 20 installed above the work table.

[0045] 8 is a diagram showing a state in which an image relating to the placement of each item is displayed on workbench 47 using projector 20. Images showing the optimum placement of each item are projected and displayed on workbench 47 by projector 20. The images are not limited to rectangles, and may be the designs of the respective items or the names of the items.

[0046] Returning to the flowchart of FIG. 4 again, if step S2 is no, the task support device 1 does not display anything.

[0047] If an image relating to the location of the items is displayed, the worker places the items to be used on the workbench 47 based on the displayed image and starts work (step S4). If an image relating to the location of the items is not displayed, the worker appropriately places the items on the workbench 47 at his / her discretion and starts work.

[0048] As a result, before starting work, the worker can easily grasp the items to be used in the work and their locations on the work bench 47, and by placing the items in those locations, the work can be carried out efficiently.

[0049] 9 is a flowchart showing the operation of the work support device 1 according to the present disclosure to display areas for improvement in work based on the workload of a worker. First, the work support device 1 acquires setting information for rating the workload (step S11).

[0050] FIG. 10 shows a screen 50 for inputting and setting information for rating the workload. On this screen, each parameter is weighted when calculating the workload based on the parameters. The worker inputs a weighting coefficient related to the distance between the worker and the item in a coefficient f1 input area 51. The worker also inputs a weighting coefficient related to the number of times the item is used in a coefficient f2 input area 52. The worker also inputs a weighting coefficient related to the weight of the item in a coefficient f3 input area 53. The coefficients are determined taking into account the degree of burden each parameter places on the worker.

[0051] Based on the input coefficients, the task support device 1 calculates a rating score when using an item using the above-mentioned formula 1. The formula for calculating the rating score is not limited to the above-mentioned formula 1 as long as it can quantify the workload.

[0052] FIG. 11 is a settings screen 60 for issuing a work improvement proposal. Specifically, a work improvement proposal is a proposal to improve the placement of items handled in the work. The "report timing" is a condition for when to issue the improvement proposal (whether to notify the worker), and the user can select whether to issue the proposal even while the worker is working, or at the start of the next time the same work is performed, in the report timing selection area 61. In other words, if "during work" is checked, the improvement proposal will be issued even while the worker is working, and if "at the start of the next work" is checked, the improvement proposal will be issued the next time the same work is performed.

[0053] The "alert threshold" is the condition for determining how large the workload must be before an improvement suggestion is issued, and can be set in the alert threshold setting area 62 so that an alert is issued when the rating score S calculated by Equation 1 reaches or exceeds a predetermined threshold. In this example, 50,000 is set in the threshold setting area 62, and an alert is issued when the rating score S reaches or exceeds 50,000.

[0054] "Rating table update frequency" is a condition for how often the rating table is updated, which is the basis for the improvement suggestions to be displayed, and the update interval can be set in the update frequency setting area 63. Here, FIG. 12 is an example of a rating table. The rating table is a table that compiles the rating score S of each item, and based on this table it is determined which item's placement should be improved. In this example, the table records the tool name, distance from the worker (cm), number of times used (times), tool weight (g), and rating score S based on Formula 1. The more frequently the rating table is updated, the more improvement suggestions based on the latest rating score S will be made even while work is in progress.

[0055] Here, the rating table is updated based on the initial value (at the start of work) of the distance (cm) between the worker and the tool, assuming that the distance does not change during work, but the rating table may be updated taking into account movement of the tool during work. For example, a variation tolerance (e.g., ±10 cm) may be set for the initial value of the distance between the worker and the tool, and distance changes within this variation tolerance may be ignored. If a change in distance occurs that exceeds this variation tolerance, the rating score S of the tool in question may be reset, the distance between the worker and the tool may be updated, and a new rating score S may be calculated.

[0056] Returning to Figure 11, the "alert method" is the method of displaying the improvement proposal, and in the example shown, the alert method selection area 64 allows selection between projection mapping onto the workbench 47 using the projector 20 and displaying on a tablet, which is the worker terminal 21.

[0057] Returning to Fig. 9, the work support device 1 acquires video of the work situation from the camera 22 (step S12). Here, Fig. 13 shows video 70 of the work situation taken by the camera 22 installed above the workbench 47, in which a worker 72 places items 73-1, 73-2, 73-3, and 73-4 (hereinafter, collectively referred to as items 73) on the workbench 71 and works while using the items 73 as appropriate.

[0058] Next, the work support device 1 uses the AI ​​analysis server 23 to recognize the worker 72 and each item 73 based on the video 70, and estimates their respective positions, the distance between the worker 72 and each item 73, and the number of times each item 73 has been used (step S13). Fig. 14 shows the video 70 that displays the positions of the worker 72 and the items 73 and the distance between the worker and the items, recognized by the AI ​​analysis server 23 based on the video 70 capturing the state of work.

[0059] The AI ​​analysis server 23 recognizes the worker and the items placed on the workbench based on a trained model (object task recognition model) that recognizes the worker and items shown based on the input video. The video 70 displays a bounding box 82 of the worker 72 and bounding boxes 83-1, 83-2, 83-3, and 83-4 of each item 73 (hereinafter, sometimes collectively referred to as bounding boxes 83) recognized by the AI ​​analysis server 23. The task support device 1 then measures the distance between the worker 72 and the item 73 based on the lengths of line segments 84-1, 84-2, 84-3, and 84-4 (hereinafter, sometimes collectively referred to as line segments 84) connecting the center of the bounding box 82 of the worker 72 and the center of the bounding box 83 of the item 73.

[0060] When this measurement is performed in two dimensions, the vertical position of the item 73 can be considered to be roughly the position of the top surface of the workbench 71. However, since the vertical position of the worker 72 varies depending on the worker 72, the vertical position of the worker 72 can be estimated based on the height information set in the height input area 33 on the screen 30 as information about the worker in Figure 5, and this can be reflected in measuring the distance between the worker 72 and the item 73.

[0061] Furthermore, the work support device 1 uses the AI ​​analysis server 23 to detect the number of times the worker 72 has used the item 73. The AI ​​analysis server 23 recognizes that the worker 72 has touched the item 73 based on the positions of the worker 72's hand and the item 73, and further recognizes that the worker 72 has used the item 73 based on the movement pattern of the worker 72's hand and the item 73. The work support device 1 then counts and stores the number of times each item 73 has been used.

[0062] Note that if the item 73 is scissors, a cutter, or the like, it may be recognized that the worker 72 has grasped the item 73. The recognition that the worker 72 has grasped the item 73 may be based on a trained model that recognizes the positions of the worker 72's hand and the object 73 captured on the basis of input video, and it may be recognized that the worker 72's hand has grasped the item 73 when the positions of the worker 72's hand and the object 73 come within a predetermined distance. Then, if the position of the object 73 is displaced while the worker 72 is grasping the object 73, and the displacement of the object 73 stops, and the position of the worker 72's hand and the position of the object 73 are separated by a predetermined distance or more, it may be determined that the object 73 has been used once.

[0063] Furthermore, the task support device 1 acquires the weight of each recognized item 73 from the database 24 .

[0064] Returning to FIG. 9, the work support device 1 calculates a rating score for each item 73 based on the acquired information on the distance between the worker 72 and the item 73, the number of times the item 73 has been used, and the weight of the item 73, using Equation 1 (step S14), and stores the calculated score together with the position and distance between the worker 72 and the item 73 and the number of times the item 73 has been used in the database 24 as a rating table (FIG. 12) (step S15).

[0065] Since the rating score increases every time an item is used, the task support device 1 determines whether the rating score is equal to or greater than the threshold at a predetermined timing (step S16). The predetermined timing may be when the rating table is updated at the update frequency set in the rating table update frequency setting area 63.

[0066] If step S16 is yes, the work support device 1 displays an improvement suggestion (step S17). The improvement suggestion may be, for example, a method of displaying a message such as "(Item name) is used frequently. Moving it closer to you is expected to improve work efficiency" on the worker terminal 21, or a method of projecting a display 86 of an item to be moved onto the work table 47 from a projector 20 installed above the work table 47 as shown in FIG. 15. Alternatively, the above message 87 may be projected onto the work table 47. If step S16 is no, no display is performed.

[0067] The work support device 1 determines whether the work has been completed (step S18), and if the work has not been completed (no in step S18), the above flow is repeated, and if the worker has completed the work (yes in step S18), the process ends. The determination of whether the work has been completed may be made, for example, by the worker operating the worker terminal 21 to that effect when the work has been completed.

[0068] As described above, the work assistance device disclosed herein acquires and displays the placement locations on the workbench of items used in the work based on the worker and the work content, allowing the worker to easily acquire the placement locations on the workbench of items used in the work and perform the work efficiently. Also, the work assistance device disclosed herein analyzes video footage of the work situation, calculates the workload based on the placement locations on the workbench of items used in the work, and notifies the worker that the placement locations of the items on the workbench should be improved based on the workload, allowing the worker to easily acquire the items whose placement locations on the workbench should be improved and easily improve the work.

[0069] In the above embodiment, it has been described that the positions where items are placed during work are constant, but the positions where items are placed may change each time an item is used. In such cases, the distance traveled each time the item is used may be calculated, and the travel distances may be accumulated to calculate the workload based on the following equation 2. Then, when this workload score 2 is equal to or greater than a predetermined threshold, a message may be displayed urging the user to change the location of the item relative to the initial position where the item was placed at the start of work, etc. [Number 2] Score 2 = (cumulative distance traveled d × coefficient f1) × (weight of item g × coefficient f3) Accumulative travel distance d: The cumulative distance traveled during the work period
