[0023] Hereinafter, examples of embodiments for carrying out the technology of the present disclosure will be described in detail with reference to the drawings.

[0024] An example of the configuration of an information processing system 10 according to this exemplary embodiment will be described with reference to Fig. 1. As shown in Fig. 1, the information processing system 10 includes a log acquisition device 12 and an information processing device 20. The information processing system 10 also includes at least one of a display device 14, an alarm device 16, and a cleaning device 18. The information processing device 20 is capable of communicating with each of the log acquisition device 12, the display device 14, the alarm device 16, and the cleaning device 18 via a network. In this exemplary embodiment, an example will be described in which the log acquisition device 12, the information processing device 20, the display device 14, the alarm device 16, and the cleaning device 18 are installed in a hospital.

[0025] The log acquisition device 12 acquires logs recording the entry and exit of people from each of a plurality of areas into which the hospital has been divided in advance, and transmits the acquired logs to the information processing device 20. The logs include identification information indicating the person, identification information indicating the area the person entered and exited, the entry time, and the exit time. The people include, for example, patients who visit the hospital, their companions, and medical staff working at the hospital.

[0026] Known devices and systems capable of acquiring a log of people entering and exiting each area can be applied as the log acquisition device 12. For example, an IC (Integrated Circuit) tag reader may be installed in each area, and when a person enters or leaves each area, the IC tag reader may read the IC tag carried by the person, thereby acquiring a log of the person's entry and exit from each area together with the person's identification information. Each person's identification information is attached to the IC tag carried by the person.

[0027] Furthermore, for example, a log of people entering and leaving each area may be acquired by capturing images of the area with a camera and performing image analysis processing on the captured video. Furthermore, a log of people entering and leaving each area may be acquired based on location information obtained using a mobile device, wearable device, tag, or the like carried by a person. Note that known methods using Bluetooth (registered trademark), wireless LAN (Local Area Network), GPS (Global Positioning System), ultrasound, or the like can be applied as a method for measuring location information.

[0028] The display device 14 is a device capable of displaying information on a screen, such as a liquid crystal display or an organic electroluminescence (EL) display. The display device 14 may be installed in a location where it can be viewed by a worker (hereinafter referred to as a "cleaning worker") who cleans each area. The display device 14 may also be a mobile terminal carried by the cleaning worker. The notification device 16 is a device capable of notifying information by, for example, lighting an LED (Light Emitting Diode) lamp or sounding a buzzer. The notification device 16 may be installed for each object to be cleaned in each area (e.g., ceiling, wall, floor, desk, etc.). The cleaning device 18 is a device capable of cleaning or sterilizing floors, walls, ceilings, desks, air, etc. in a hospital. Examples of the cleaning device 18 include a mobile device having a cleaning means (e.g., a traveling robot or drone), an ultraviolet ray irradiation device, a disinfectant spray device, and an air purifier equipped with a dust collection filter such as a HEPA (High Efficiency Particulate Air) filter.

[0029] The information processing device 20 according to this exemplary embodiment has a function of issuing cleaning instructions to cleaning workers and instructions to the cleaning device 18 to perform cleaning via the display device 14 and the alarm device 16, depending on the presence of people in each area. It is generally known that the more people gather in an area and the longer they stay there, the higher the possibility of infectious diseases spreading. In order to prevent the spread of infectious diseases, it is considered preferable to focus cleaning on areas where people gather in a crowded state and stay for a long time. An example of the configuration of the information processing device 20 according to this exemplary embodiment will be described below.

[0030] First, the hardware configuration of the information processing device 20 according to this exemplary embodiment will be described with reference to Fig. 2. As shown in Fig. 2, the information processing device 20 includes a CPU (Central Processing Unit) 81, a non-volatile storage unit 82, and a memory 83 as a temporary storage area. The information processing device 20 also includes a display 84 such as a liquid crystal display, an input unit 85 such as a keyboard and a mouse, and a network I / F (Interface) 86 connected to a network. The CPU 81, the storage unit 82, the memory 83, the display 84, the input unit 85, and the network I / F 86 are connected via a bus 88 such as a system bus and a control bus so as to be able to exchange various types of information with each other.

[0031] The storage unit 82 is realized by a storage medium such as a hard disk drive (HDD), a solid state drive (SSD), or a flash memory. An information processing program 87 is stored in the storage unit 82. The CPU 81 reads the information processing program 87 from the storage unit 82, loads it into the memory 83, and executes the loaded information processing program 87. The CPU 81 is an example of a processor of the present disclosure.

[0032] Next, a functional configuration of the information processing device 20 according to this exemplary embodiment will be described with reference to Fig. 3. As shown in Fig. 3, the information processing device 20 includes a first generation unit 22, a second generation unit 24, and a control unit 26. A CPU 81 executes an information processing program 87, thereby functioning as the first generation unit 22, the second generation unit 24, and the control unit 26.

[0033] The first generation unit 22 acquires the log transmitted from the log acquisition device 12 via the network I / F 86, and generates presence information for each area based on the log, which is information indicating the presence status of people in each of the multiple areas.

[0034] The second generator 24 acquires the presence information for each area generated by the first generator 22, and generates cleaning information for each of the multiple areas based on the presence information to instruct cleaning of the area. The method for generating the cleaning information is not particularly limited, but may use a correspondence table in which the presence information and the cleaning information are previously associated, or may calculate the cleaning information using a formula that uses the presence information as a variable.

[0035] In this exemplary embodiment, a form will be described in which the second generation unit 24 generates cleaning information using a method using a correspondence table T shown in FIG. 4. As shown in FIG. 4, the correspondence table T pre-records cleaning information corresponding to presence information. The second generation unit 24 compares the presence information acquired from the first generation unit 22 with the correspondence table T for each area to identify the cleaning information corresponding to the presence information. The correspondence table T is stored in the storage unit 82, for example.

[0036] 4, the presence information according to this exemplary embodiment includes information indicating the number of people who have been present in an area within a predetermined period of time (hereinafter referred to as the "number of people present") and the total time that people have been present in the area within the predetermined period of time. The predetermined period of time is, for example, the period from the time the previous cleaning was performed to the time the processing by the first generation unit 22 starts. The total time is the cumulative total of the time from when one person enters an area until when they leave (hereinafter referred to as the "presence time") for all people who have entered the area.

[0037] 4, the cleaning information according to this exemplary embodiment includes, as instructions for cleaning an area, information on at least one of whether cleaning is necessary, cleaning time, cleaning means, and cleaning target. Examples of cleaning means include a cleaning worker and cleaning device 18. Examples of cleaning targets include a ceiling, wall, floor, desk, and air.

[0038] The control unit 26 controls at least one of the display device 14, the notification device 16, and the cleaning device 18 based on the cleaning information generated by the second generation unit 24. Specifically, the control unit 26 controls the display device 14 to display a command to clean the area based on the cleaning information. The control unit 26 also controls the notification device 16 to issue a command to clean the area based on the cleaning information. The control unit 26 also controls the cleaning device 18 to clean the area based on the cleaning information.

[0039] Furthermore, the control unit 26 may terminate control of the display device 14, the notification device 16, and the cleaning device 18 when cleaning of the area instructed to be cleaned is completed. Completion of cleaning by the cleaning worker can be detected, for example, by image processing of moving images captured by a camera. Completion of cleaning by the cleaning device 18 can be detected by receiving a signal from the cleaning device 18 indicating completion of cleaning. Furthermore, the control unit 26 may control the display device 14 and the notification device 16 to notify the user that cleaning has not been completed within a predetermined period of time since the cleaning instruction was issued.

[0040] [Specific example] Specific examples of the processing by the first generation unit 22, the second generation unit 24, and the control unit 26 will be described with reference to FIGS. 5 to 7. FIG. 5 is a top view showing a specific example of a room R in a hospital. As shown in FIG. 5, the multiple areas in this specific example are obtained by subdividing the room R into nine areas A1 to A9. In FIG. 5, people a to n are shown as circles. FIG. 6 is a diagram that visualizes the log of the entry and exit of people a to n in each of the areas A1 to A9. In FIG. 6, the presence time of people a to n from their entry to their exit in the areas A1 to A9 is shown as black. FIG. 7 is a diagram showing the presence information and cleaning information for each of the areas A1 to A9, generated by the first generation unit 22 and the second generation unit 24.

[0041] As an example, the generation process of presence information and cleaning information for area A1 will be described. Based on the log (see FIG. 6), the first generation unit 22 calculates the number of people present in area A1 during a predetermined period (9:00 to 11:15) to be 6 people (people a to f). Based on the log (see FIG. 6), the first generation unit 22 also calculates the total time spent in area A1 during the predetermined period (9:00 to 11:15) to be 90 minutes. As shown in FIG. 7, the first generation unit 22 generates information including these values ​​as presence information for area A1.

[0042] The second generation unit 24 acquires the presence information generated by the first generation unit 22 and compares it with correspondence table T (see FIG. 4). Since the number of people present in area A1 is 6 and the total time is 90 minutes, the second generation unit 24 generates the cleaning information in the third row from the top of correspondence table T (see FIG. 4) (cleaning necessity is "necessary", cleaning time is "4 minutes", cleaning method is "worker, cleaning device", and object to be cleaned is "desk, floor") as the cleaning information for area A1.

[0043] Based on the cleaning information, the control unit 26 controls the display device 14 to display a message such as "Please clean the desk in area A1 for four minutes," thereby instructing the cleaning worker to clean the desk. The control unit 26 also instructs the cleaning worker to clean by causing the alarm device 16 to issue an alarm indicating that area A1 should be cleaned. The control unit 26 also controls the cleaning device 18 to clean the floor in area A1 for four minutes.

[0044] The first generation unit 22, the second generation unit 24, and the control unit 26 perform the same process for the other areas A2 to A9.

[0045] Next, the operation of the information processing device 20 according to this exemplary embodiment will be described with reference to Fig. 8. The information processing shown in Fig. 8 is performed by the CPU 81 executing the information processing program 87. The information processing shown in Fig. 8 is performed at a predetermined timing when cleaning is possible, such as during a break.

[0046] 8, the first generation unit 22 acquires the log transmitted from the log acquisition device 12 via the network I / F 86. In step S12, the first generation unit 22 generates presence information for each of the multiple areas based on the log acquired in step S10.

[0047] In step S14, the second generator 24 acquires the presence information generated in step S12 and generates cleaning information for each of the multiple areas based on the presence information. In step S16, the controller 26 controls at least one of the display device 14, the alarm device 16, and the cleaning device 18 based on the cleaning information generated in step S14.

[0048] As described above, the information processing device according to this exemplary embodiment includes at least one processor. The processor acquires presence information for each of a plurality of areas, which indicates the presence status of people in each of the areas. Based on the presence information, the processor generates cleaning information for each of the plurality of areas, instructing cleaning of the area. Therefore, cleaning can be performed according to the status of each area, which makes it possible to focus cleaning on areas where the spread of infectious diseases is likely, which is advantageous for preventing the spread of infectious diseases. Furthermore, cleaning can be omitted for areas where the spread of infectious diseases is unlikely, which is advantageous for improving the efficiency of cleaning work.

[0049] In the above exemplary embodiment, the method of dividing the multiple areas is not particularly limited. For example, one room in a hospital may be subdivided into multiple areas (see FIG. 5), one room may be considered as one area, or multiple rooms may be collectively considered as one area. Furthermore, for example, the division of the multiple areas may be set in advance according to the tolerance level of contamination of the areas by applying concepts such as zoning and cohorting in hospitals.

[0050] Other examples of how to divide the image into a plurality of regions will be described below by taking modified examples of the above specific examples. [First Modification] In the above specific example, cleaning information is generated indicating that cleaning of area A4 is not necessary, as shown in Figure 7. However, since area A4 contains person i in a position close to people k and j who are in area A5 that requires cleaning, it is considered more preferable to clean the area of ​​area A4 near area A5 where person i is located.

[0051] In order to perform cleaning that includes such areas, the multiple areas in this exemplary embodiment may include areas that overlap with other areas (hereinafter referred to as "overlapping areas"). In addition to areas A1 to A9 in room R similar to that in FIG. 5, Fig. 9 also illustrates overlapping areas S12, S23, S45, S56, S78, and S89, which each span two of areas A1 to A9 that are adjacent to each other in the left-right direction, with dashed dotted lines. Hereinafter, when areas A1 to A9 are not distinguished, they will be referred to as "area A," and when overlapping areas S12, S23, S45, S56, S78, and S89 are not distinguished, they will be referred to as "overlapping areas S."

[0052] In this case, the first generation unit 22 and the second generation unit 24 generate presence information and cleaning information for the overlapping area S in addition to the area A. Fig. 10 shows the presence information and cleaning information generated for each of the area A and the overlapping area S shown in Fig. 9 based on the correspondence table T in Fig. 4 and the log in Fig. 6. For the area where the area A and the overlapping area S overlap, the control unit 26 performs various controls by adopting the cleaning information generated for the area A and the overlapping area S, whichever has the longer cleaning time and includes the larger number of cleaning means and cleaning locations.

[0053] For example, the control unit 26 performs various controls for the overlapping area between area A4 and overlapping area S45 based on the cleaning information for overlapping area S45, which has a longer cleaning time and more cleaning means and cleaning locations. This configuration allows appropriate cleaning information to be generated for not only areas where the spread of infectious diseases is likely, but also for surrounding areas. This further reduces the spread of infectious diseases.

[0054] In this modified example, for the sake of simplicity, we have described a form that includes overlapping areas that span two of the regions A1 to A9 that are adjacent in the left-right direction, but it is more preferable to include overlapping areas that span two of the regions A1 to A9 that are adjacent in the depth direction.

[0055] [Second Modification] In the above specific example, an example was described in which room R was equally divided into nine parts, as shown in Figure 5. However, for example, when cleaning is performed between regular hospital operations, if the area to be cleaned is large, it may be difficult to secure the time for cleaning. Therefore, it is considered preferable to further divide the area for areas that are known to be prioritized for cleaning based on past performance, such as areas with a high number of people coming and going or areas where people stay for long periods of time.

[0056] Therefore, the division of the multiple areas in this exemplary embodiment may be set in advance according to past records regarding the presence status of people. Fig. 11 shows an example in which a room R similar to that in Fig. 5 is divided into areas B1 to B9 according to past records regarding the presence status of people. Fig. 12 shows the presence information and cleaning information generated for the example in Fig. 11 based on the correspondence table T in Fig. 4 and the log in Fig. 6.

[0057] For example, areas B5 and B6 correspond to areas obtained by further dividing area A5 in Fig. 5, and different cleaning information is generated depending on the presence information for each area, as shown in Fig. 12. Therefore, when cleaning area B5, cleaning appropriate for area B5 can be performed without interfering with other work being done in area B6, which is advantageous for improving the efficiency of cleaning work.

[0058] In the exemplary embodiment, the presence information may be determined based on the protection status of people present in the area. This is because protected people are considered less likely to spread infectious diseases than unprotected people. The protection status is determined, for example, by whether masks and protective clothing are worn, and whether hand washing, gargling, and alcohol disinfection are performed. Determining the presence information based on the protection status of people present in the area is advantageous in improving the efficiency of cleaning work while appropriately suppressing the spread of infectious diseases.

[0059] In this case, for example, the first generation unit 22 may weight the number of people present and the time they are present depending on whether or not they are wearing a mask, such as counting a person wearing a mask as 0.5 people in the number of people present. Furthermore, the first generation unit 22 may weight the number of people present and the time they are present depending on the type of mask, such as a nonwoven mask, a gauze mask, a surgical mask, or a particulate mask. Note that whether or not a person is wearing a mask and the type of mask can be determined based on, for example, an image obtained by photographing the person with a camera.

[0060] In this case, the first generating unit 22 may weight the number of people present and the time they are present depending on the state of hand washing, for example, by counting a person who does not wash their hands sufficiently as 1.5 people. Whether hand washing is sufficient or not can be determined, for example, by a function of a wearable device such as a smartwatch, based on whether the time determined to be spent washing hands is equal to or longer than a predetermined threshold.

[0061] In the above exemplary embodiment, the presence information includes information indicating the number of people present and the total time, but this is not limiting. For example, the presence information may include information indicating only one of the number of people present and the total time.

[0062] Furthermore, in the above exemplary embodiment, the first generation unit 22 may track people's movement between areas, and if a person who leaves an area returns to the same area, the presence information may be generated without counting the number of people present in that area twice. This is because it is considered unlikely that the same person returning to the same area will further spread the infection. By generating presence information that does not include the same person twice, cleaning can be more tailored to the condition of each area. Furthermore, tracking people's movement between areas is also advantageous for identifying infection routes. Known methods can be applied to track people's movement between areas, such as methods using identification information from IC tags and methods using facial recognition by cameras.

[0063] Furthermore, in the above exemplary embodiment, the second generator 24 may generate cleaning information by taking into account various information in addition to the presence information. For example, the second generator 24 may generate cleaning information based on the tolerance for contamination of an area in addition to the presence information. This is because, in areas requiring high cleanliness, such as operating rooms, cleaning should be performed with fewer people and in a shorter total time than in areas requiring less cleanliness, such as garbage disposal rooms. The second generator 24 may generate cleaning information using multiple correspondence tables T, each different for each tolerance for contamination of an area. The multiple correspondence tables T, each different for each tolerance for contamination of an area, are stored in advance in the storage unit 82. The tolerance for contamination of an area is determined, for example, based on concepts such as zoning and cohorting in hospitals. This configuration allows cleaning to be performed based on the tolerance for contamination of an area in addition to the condition of each area.

[0064] Furthermore, for example, the second generator 24 may generate cleaning information based on the air flow in the area in addition to the presence information. This is because infectious disease-causing viruses are considered more likely to remain downstream than upstream in air flows created by air conditioning, windows, ventilation openings, etc. In other words, downstream areas are considered more likely to spread infectious diseases than upstream areas, so cleaning should be performed with fewer people present and in a shorter total time. Therefore, when air flows are formed across multiple areas, the second generator 24 may generate cleaning information using multiple correspondence tables T, each different for each air flow, such as upstream and downstream. The multiple correspondence tables T, each different for each air flow, are stored in the storage unit 82 in advance. Known methods, such as methods using an infrared camera and a particle image velocimetry, can be used to detect air flows. This configuration allows cleaning to be performed based on not only the condition of each area but also the air flow in the area.

[0065] Furthermore, for example, the second generator 24 may generate cleaning information based on the area of ​​the area in addition to the presence information. This is because the smaller the area, the more preferable it is to perform cleaning with fewer people present and in a shorter total time. Specifically, when the areas differ from one another as described in the second modified example above, the second generator 24 may generate cleaning information using multiple correspondence tables T that differ for each area. The multiple correspondence tables T that differ for each area are stored in advance in the storage unit 82. This configuration allows cleaning that is more suited to the condition of each area.

[0066] In the exemplary embodiment, the second generator 24 may generate disinfection information for instructing disinfection for each of a plurality of people present in one of a plurality of areas based on the presence information. Examples of "disinfection" include hand washing, gargling, alcohol disinfection, and irradiating with ultraviolet light at a wavelength of 222 nm, which is safe for the human body and can inactivate viruses. Specifically, the second generator 24 generates disinfection information instructing disinfection for people who have been present in an area (hereinafter referred to as a "disinfection target area") where the number of people present and the total time spent there are equal to or greater than predetermined thresholds. In this case, the controller 26 controls the display device 14 and the alarm device 16 to instruct disinfection of the people based on the disinfection information generated by the second generator 24. This configuration can further prevent the spread of infectious diseases.

[0067] In this case, if a person who was in the disinfection target area moves to another area that is not the disinfection target area, the second generation unit 24 may generate disinfection information that instructs other people who were in the area after the move to disinfect it. Furthermore, if a person who was in the disinfection target area moves to another area that is not the disinfection target area, the second generation unit 24 may generate cleaning information that instructs cleaning of the area after the move. According to these embodiments, even if an area is not subject to disinfection alone, if there is a possibility that a virus has been brought in from the disinfection target area, it is possible to disinfect people who are in the area and clean the area, thereby further suppressing the spread of infectious diseases.

[0068] In this case, the second generator 24 may generate disinfection information by taking into account the amount and duration of speech a person makes within the area, the orientation of the person's face relative to the airflow, and the degree of proximity to other people. This information can be obtained, for example, based on an image of the person captured by a camera. This configuration can further prevent the spread of infectious diseases.

[0069] Furthermore, in the above exemplary embodiment, the control unit 26 may perform control to instruct cleaning of the area designated by the cleaning information, taking into account a margin. For example, in addition to the area designated for cleaning, the control unit 26 may also instruct cleaning of other areas adjacent to the designated area. Furthermore, for example, the control unit 26 may instruct cleaning of an area that is an area expanded by a predetermined area from the area designated for cleaning. This configuration can further suppress the spread of infectious diseases.

[0070] Furthermore, in the exemplary embodiment described above, when the control unit 26 detects based on the cleaning information that cleaning may be necessary, it may control the display device 14 and the alarm device 16 to notify the user of this fact. For example, the control unit 26 may notify a message such as, "This area is becoming congested, so cleaning will be required soon." Whether cleaning is likely to be necessary can be detected, for example, by whether the total time is within a predetermined range from the lower limit of the total time for which cleaning is required in the correspondence table T shown in FIG. 4. This configuration can assist in determining the timing for people to take measures to prevent the spread of infectious diseases, such as leaving the area, restricting entry to the area, isolating people, ventilating, and cleaning, which is advantageous in preventing the spread of infectious diseases.

Also, multiple processing units may be configured with a single processor.

[0075] Examples of configuring multiple processing units with a single processor include, first, a form in which one processor is configured with a combination of one or more CPUs and software, and this processor functions as multiple processing units, as typified by computers such as client and server. Second, a form in which a processor is used to realize the functions of the entire system including multiple processing units with a single IC (Integrated Circuit) chip, as typified by systems on chips (SoCs). In this way, various processing units are configured using one or more of the above-mentioned various processors as a hardware structure.

[0076] Furthermore, more specifically, the hardware structure of these various processors can be an electric circuit that combines circuit elements such as semiconductor elements.

[0077] In the above exemplary embodiment, the information processing program 87 is pre-stored (installed) in the storage unit 82, but this is not limiting. The information processing program 87 may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), or a USB (Universal Serial Bus) memory. The information processing program 87 may also be downloaded from an external device via a network. Furthermore, the technology of the present disclosure extends to not only information processing programs but also storage media that non-temporarily store information processing programs.
