[Modes for carrying out the invention]
[0008] Several embodiments will be described below with reference to the drawings. Note that the scale of the parts in the drawings used in the following description of embodiments may have been changed as appropriate. Also, for illustrative purposes, some components may be omitted from the drawings used in the following description of embodiments.
[0009] <Embodiment> (Example configuration) (Hygiene Management System) Figure 1 is a block diagram showing an example configuration of the hygiene management system S. The hygiene management system S is a system applied in facilities where proper hand hygiene needs to be maintained. For example, the facility is a food manufacturing plant or store where people handle food directly with their hands, but is not limited to this. The hygiene management system S manages the history of each person's hand hygiene. The people whose hand hygiene history is managed by the hygiene management system S are the employees of the facility and other people who use the hygiene management system S. Hereafter, people who use the hygiene management system S will also be referred to as users.
[0010] For example, hand hygiene includes, but is not limited to, the condition of the hands before handwashing, the results of the handwashing action, and whether gloves are being worn. Handwashing shall consist of several designated actions. Designated actions are categorized by the area to be washed and are the hand actions specified in handwashing. Here, the multiple designated actions will be explained as six designated actions. The six designated actions are: lathering well, rubbing the backs of the hands, rubbing between the fingers, rubbing the thumbs, rubbing the fingertips, and rubbing the wrists. The number and content of designated actions are not limited to these.
[0011] For example, a user washes their hands before entering a specific area within the facility. They also wash their hands again if they leave the area for a restroom break or to perform another task and then re-enter the area. Therefore, a user may wash their hands multiple times a day.
[0012] The hygiene management system S includes a hygiene management device 1, a hand imaging device 2, an action determination device 3, and a glove imaging device 4. The hand imaging device 2, the action determination device 3, and the glove imaging device 4 are devices installed in the facility.

The hygiene management system S is an example of a system including one or more devices among the hygiene management device 1, the hand imaging device 2, the action determination device 3, and the glove imaging device 4.
[0013] Each device included in the hygiene management system S is communicably connected to each other via a network NW. For example, the network NW is a LAN (Local Area Network). The LAN may be a wireless LAN or a wired LAN. When the hygiene management device 1 is a device outside the facility, the network NW may be composed of at least one network such as the Internet and a LAN.
[0014] The hygiene management device 1 is a device that manages the history of the hygiene state of each person's hands.

The hand image can include images of the fingers of the left and right hands. The image of the user's hand before handwashing is an example of an image related to the hygiene state of the user's hand.
[0015] The operation determination device 3 is a device that determines the handwashing operation of a user based on a captured image. The captured image is an image of the user during handwashing captured by a camera. The handwashing operation is the movement of the hands during handwashing. Determining the handwashing operation can include specifying the content of the handwashing operation. Determining the handwashing operation can include determining whether the handwashing operation passes. That the handwashing operation passes means that the handwashing operation has been appropriately performed. That the handwashing operation fails means that the handwashing operation has not been appropriately performed.
[0016] The glove imaging device 4 is a device that acquires an image of the user wearing gloves after handwashing based on a captured image. The captured image is an image of the user after handwashing captured by a camera. The glove-wearing image is an image of the glove-wearing state.

[0072] The processor 10 of the hygiene management device 1 performs user authentication processing (ACT100). ACT100 may also be processed by the authentication processing unit 101. In ACT100, for example, the processor 10 authenticates the user by comparing the input user identification information with the identification information of each person registered in the NVM 13. The processor 10 identifies the authenticated user as the person whose hand hygiene status history will be updated.
[0073] The processor 20 of the manual imaging device 2 receives user injury information (ACT201) based on user input operations. ACT201 may also be processed by the reception unit 202. The processor 20 of the manual imaging device 2 transmits the user's injury information, entered based on the user's input operation, to the hygiene management device 1 (ACT202).

[0078] The processor 10 of the hygiene management device 1 receives images of the user's hands before handwashing from the hand imaging device 2, based on images captured by the camera 251 (ACT103). ACT103 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 receives an image of the user's hands before handwashing and saves the image of the user's hands before handwashing as the user's history in the NVM 13 (ACT 104). ACT 104 may also be processed by the first storage processing unit 105.
[0079] In this way, the hygiene management device 1 or hygiene management system S can manage the user's hand image before handwashing as a history of hygiene status that does not depend on human input.
[0080] The processor 20 of the hand imaging device 2 transmits first time information to the hygiene management device 1 (ACT205). ACT205 may also be processed by the communication processing unit 204. The first time information is information indicating a first time related to the user's hand image before hand washing. For example, the first time is the time when the user's hand image before hand washing is acquired by the hand imaging device 2, but is not limited to this. The first time may also be the time when the user starts using the hand imaging device 2. The first time may also be the time when the user finishes using the hand imaging device 2. The processor 20 may transmit first time information for one first time, or it may transmit first time information for each of multiple first time points.
[0081] The processor 10 of the hygiene management device 1 receives first time information from the manual camera device 2 (ACT105). ACT105 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 saves the first time information as user history in the NVM 13 based on the reception of the first time information (ACT 106). ACT 106 may also be processed by the first storage processing unit 105.
[0082] The processor 30 of the operation determination device 3 transmits second time information to the hygiene management device 1 (ACT300). ACT300 may also be processed by the communication processing unit 302. The second time information is information indicating a second time related to the user's handwashing action. For example, the second time is the start time of the user's handwashing action, but is not limited to this. The second time may also be the start time of the user's use of the operation determination device 3. The processor 20 may transmit second time information for one second time, or it may transmit second time information for each of multiple second times.
[0083] The processor 10 of the hygiene management device 1 receives second time information from the operation determination device 3 (ACT107). ACT107 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 saves the second time information as user history in the NVM 13 based on the reception of the second time information (ACT 108). ACT 108 may also be processed by the first storage processing unit 105.
[0084] The processor 30 of the motion determination device 3 determines the user's hand-washing action (ACT301) based on the image captured by the camera 351. ACT301 may also be processed by the determination processing unit 301.
[0085] The processor 30 of the motion determination device 3 transmits the result of the user's handwashing action, based on the image captured by the camera 351, to the hygiene management device 1 (ACT302). ACT302 may also be processed by the communication processing unit 302. The result of the user's handwashing action determination is based on the judgment of the user's handwashing action by the motion determination device 3. For example, the result of the user's handwashing action determination indicates whether the user's handwashing action is acceptable or unacceptable.
[0086] The processor 10 of the hygiene management device 1 receives the result of the user's handwashing action, based on the image captured by the camera 351, from the action determination device 3 (ACT109). ACT109 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 receives the result of the user's handwashing action and saves the result of the user's handwashing action as the user's history in the NVM 13 (ACT 110). ACT 110 may also be processed by the first storage processing unit 105.
[0087] In this way, the hygiene management device 1 or hygiene management system S can manage the results of the user's handwashing actions as a history of hygiene status that does not depend on human input.
[0088] The processor 10 may also save images of the user's hands taken by the camera 351 during handwashing to the NVM 13 as the user's history.
[0089] The processor 30 of the operation determination device 3 transmits a third time information to the hygiene management device 1 (ACT303). ACT303 may also be processed by the communication processing unit 302. The third time information is information indicating a third time related to the user's handwashing action. For example, the third time is the end time of the user's handwashing action, but is not limited to this. The third time may also be the time the operation determination device 3 determines the user's handwashing action. The third time may also be the time the user finishes using the operation determination device 3. The processor 30 may transmit the third time information for one third time, or it may transmit the third time information for each of multiple third times.
[0090] The processor 10 of the hygiene management device 1 receives third time information from the operation determination device 3 (ACT111). ACT111 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 saves the third time information as user history in the NVM 13 based on the reception of the third time information (ACT 112). ACT 112 may also be processed by the first storage processing unit 105.
[0091] The processor 40 of the glove imaging device 4 acquires an image of the user wearing gloves after handwashing, based on the image captured by the camera 451 (ACT400). ACT400 may also be processed by the acquisition unit 401. The processor 40 of the glove imaging device 4 transmits an image of the user wearing gloves after handwashing, based on the image captured by the camera 451, to the hygiene management device 1 (ACT401). ACT401 may also be processed by the communication processing unit 402.
[0092] The processor 10 of the hygiene management device 1 receives an image of the user wearing gloves after handwashing from the glove imaging device 4, based on an image captured by the camera 451 (ACT113). ACT113 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 receives an image of the user wearing gloves after handwashing and saves the image of the user wearing gloves after handwashing as a user history in the NVM 13 (ACT 114). ACT 114 may also be processed by the first storage processing unit 105.
[0093] In this way, the hygiene management device 1 or hygiene management system S can manage images of the user wearing gloves after handwashing as a history of hygiene status that does not depend on human input.
[0094] The processor 40 of the glove imaging device 4 transmits a fourth time information to the hygiene management device 1 (ACT402). ACT402 may also be processed by the communication processing unit 402. The fourth time information is information indicating a fourth time related to the image of the user wearing gloves after hand washing. For example, the fourth time is the time when the image of the user wearing gloves after hand washing is acquired by the glove imaging device 4, but is not limited to this. The fourth time may also be the time when the user starts using the glove imaging device 4. The fourth time may also be the time when the user finishes using the glove imaging device 4. The processor 40 may transmit the fourth time information for one fourth time, or it may transmit the fourth time information for each of multiple fourth times.
[0095] The processor 10 of the hygiene management device 1 receives the fourth time information from the glove imaging device 4 (ACT115). ACT115 may also be processed by the first communication processing unit 102. The processor 10 of the hygiene management device 1 saves the fourth time information as user history in the NVM 13 based on the reception of the fourth time information (ACT 116). ACT 116 may also be processed by the first storage processing unit 105.
[0096] Figure 11 is a sequence diagram showing an example of the output processing of the first alert information in the hygiene management system S.
[0097] The processor 10 of the hygiene management device 1 compares the user's wound information with an alert condition (ACT120). ACT120 may also be processed by the comparison unit 108. The alert condition is a condition for causing the output unit of the input / output device 261 connected to the hand imaging device 2 to output the first alert information. The alert condition is a condition for distinguishing whether the user's hand hygiene is appropriate in terms of wounds. If the wound information satisfies the alert condition, it can be said that the user's hand hygiene is not appropriate in terms of wounds. If the wound information does not satisfy the alert condition, it can be said that the user's hand hygiene is appropriate in terms of wounds. The alert condition may also be that there is a wound on the hand. The alert condition may also be that there is bleeding from the wound. The alert condition may also be that the size of the wound is larger than the standard. The alert condition may also be that the number of wounds is greater than the standard. The first alert information is a notification based on the wound information satisfying the alert condition. The first alert information may also be information indicating that the wound information satisfies the alert condition. The first alert information may also be information prompting the user to carefully wash the wound area. The first alert information is an example of the first notification based on the damage information meeting the alert conditions.
[0098] If the user's injury information meets the alert conditions, the processor 10 of the hygiene management device 1 transmits a first instruction (ACT121) to the manual imaging device 2. ACT121 may also be processed by the first communication processing unit 102. The first instruction is an instruction to output the first alert information at the output unit of the input / output device 261.
[0099] The processor 20 of the manual imaging device 2 receives a first instruction (ACT220) from the hygiene management device 1. ACT220 may also be processed by the communication processing unit 204. The processor 20 of the manual imaging device 2 causes the output unit of the input / output device 261 to output first alert information based on the first instruction (ACT221). ACT221 may also be processed by the output processing unit 205. In ACT221, for example, the processor 20 may display the first alert information on the display unit. The processor 20 may also output the first alert information as sound on the audio output unit. In this way, if the user's injury information satisfies the alert conditions, the processor 20 can output the first alert information on the output unit of the input / output device 261.
[0100] In this way, the hygiene management device 1 or hygiene management system S can prompt the user to carefully wash the wound area based on the first alert information.
[0101] Figure 12 is a sequence diagram showing an example of the output processing of the second alert information in the hygiene management system S.
[0102] The processor 10 of the hygiene management device 1 calculates a first interval from a first time to a second time (ACT130). ACT130 may also be processed by the comparison unit 108. In ACT130, for example, the processor 10 calculates a first interval from a first time to a second time based on the first time information and the second time information.
[0103] The processor 10 of the hygiene management device 1 compares the first interval with a first predetermined time (ACT131). ACT131 may also be processed by the comparison unit 108. The first predetermined time is a time specified to manage the risk of touching unnecessary places with bare hands. The first predetermined time is used to distinguish whether the first interval is appropriate. For example, as the first interval lengthens, the likelihood of the user touching unnecessary places with bare hands between the acquisition of a hand image by the hand imaging device 2 and the start of the handwashing action increases. If the first interval is not within the first predetermined time, there is a high probability that the user has touched unnecessary places with bare hands. In this case, the first interval can be said to be inappropriate. If the first interval is within the first predetermined time, there is a low probability that the user has touched unnecessary places with bare hands. In this case, the first interval can be said to be appropriate. The length of the first predetermined time can be set as appropriate.
[0104] If the first interval is not within the first predetermined time, the processor 10 of the hygiene management device 1 transmits a second instruction to the operation determination device 3 (ACT132). ACT132 may also be processed by the first communication processing unit 102. The second instruction may include an instruction to stop the operation determination device 3 from determining whether the user has washed their hands. The second instruction may include an instruction to output second alert information at the output unit of the input / output device 361. The second alert information is a notification based on the fact that the first interval is not within the first predetermined time. The second alert information may also be information indicating that the first interval is not within the first predetermined time. The second alert information may also be information prompting the user to restart from acquiring an image of their hands before washing their hands. The second alert information is an example of a second notification based on the fact that the first interval is not within the first predetermined time.
[0105] The processor 30 of the operation determination device 3 receives a second instruction from the hygiene management device 1 (ACT330). ACT330 may also be processed by the communication processing unit 302. The processor 30 of the operation determination device 3 stops the process of determining whether the user has washed their hands based on the second instruction (ACT331). ACT331 may also be processed by the determination processing unit 301. In this way, if the first interval is not within the first predetermined time, the processor 30 can stop the process of determining whether the user has washed their hands. Since the processor 30 stops the process of determining whether the user has washed their hands, it does not derive a result of determining whether the user has washed their hands.
[0106] If the first interval is not within the first predetermined time, the user is likely to repeat the handwashing process. Therefore, the result of the user's handwashing action before repeating the handwashing process is of little need as a history of hygiene status. The hygiene management device 1 or hygiene management system S can reduce its processing load by stopping the process of determining the user's handwashing action.
[0107] The processor 30 of the operation determination device 3 causes the output unit of the input / output device 361 to output the second alert information based on the second instruction (ACT332). ACT332 may also be processed by the output processing unit 303. In ACT332, for example, the processor 30 may display the second alert information on the display unit. The processor 30 may also output the second alert information as sound on the audio output unit. In this way, if the first interval is not within the first predetermined time, the processor 30 can cause the output unit of the input / output device 361 to output the second alert information.
[0108] In this way, the hygiene management device 1 or hygiene management system S can prompt the user to restart the process from acquiring an image of the user's hands before handwashing, based on the second alert information.
[0109] The processor 10 of the hygiene management device 1 may save the first comparison result between the first interval and the first predetermined time as the user history in the NVM 13. This process may also be performed by the second storage processing unit 106. The first comparison result is a result derived based on the comparison between the first interval and the first predetermined time. For example, the first comparison result indicates that the first interval is within the first predetermined time, or that the first interval is not within the first predetermined time.
[0110] This allows the hygiene management device 1 or hygiene management system S to manage the first comparison result as a history of hygiene status that does not depend on human input. By checking the first comparison result, the administrator can confirm the high probability that the user did not touch unnecessary areas with their bare hands during handwashing.
[0111] The processor 30 of the operation determination device 3 may process only one of ACT331 and ACT332.
[0112] Figure 13 is a sequence diagram showing an example of the output processing of the third alert information in the hygiene management system S.
[0113] The processor 10 of the hygiene management device 1 calculates a second interval from the third time to the fourth time (ACT140). ACT140 may also be processed by the comparison unit 108. In ACT140, for example, the processor 10 calculates a second interval from the third time to the fourth time based on the third time information and the fourth time information.
[0114] The processor 10 of the hygiene management device 1 compares the second interval with a second predetermined time (ACT141). ACT141 may also be processed by the comparison unit 108. The second predetermined time is a time specified to manage the risk of touching unnecessary places with bare hands. The second predetermined time is used to distinguish whether the second interval is appropriate. For example, as the second interval lengthens, the likelihood of a user touching unnecessary places with bare hands between the end of handwashing and before putting on gloves increases. If the second interval is not within the second predetermined time, there is a high probability that the user has touched unnecessary places with bare hands. In this case, the second interval can be said to be inappropriate. If the second interval is within the second predetermined time, there is a low probability that the user has touched unnecessary places with bare hands. In this case, the second interval can be said to be appropriate. The length of the second predetermined time can be set as appropriate.
[0115] If the second interval is not within the second predetermined time, the processor 10 of the hygiene management device 1 transmits a third instruction to the glove imaging device 4 (ACT142). ACT142 may also be processed by the first communication processing unit 102. The third instruction may include an instruction to cause the output unit of the input / output device 461 to output a third alert information. The third alert information is a notification based on the fact that the second interval is not within the second predetermined time. The third alert information may also be information indicating that the second interval is not within the second predetermined time. The third alert information may also be information prompting the user to restart from acquiring an image of their hands before handwashing. The third alert information is an example of a third notification based on the fact that the second interval is not within the second predetermined time.
[0116] The processor 40 of the glove imaging device 4 receives a third alert instruction from the hygiene management device 1 (ACT440). ACT440 may also be processed by the communication processing unit 402.
[0117] The processor 40 of the glove imaging device 4 causes the output unit of the input / output device 461 to output third alert information based on the third instruction (ACT441). ACT441 may also be processed by the output processing unit 403. In ACT441, for example, the processor 40 may display the third alert information on the display unit. The processor 40 may also output the third alert information as sound from the audio output unit. In this way, if the second interval is not within the second predetermined time, the processor 40 can cause the output unit of the input / output device 461 to output the third alert information.
[0118] In this way, the hygiene management device 1 or hygiene management system S can prompt the user to restart the process from acquiring an image of the user's hands before handwashing, based on the third alert information.
[0119] The processor 10 of the hygiene management device 1 may save the second comparison result between the second interval and the second predetermined time as the user history in the NVM 13. This process may also be performed by the second storage processing unit 106. The second comparison result is a result derived based on the comparison between the second interval and the second predetermined time. For example, the second comparison result indicates that the second interval is within the second predetermined time, or that the second interval is not within the second predetermined time.
[0120] This allows the hygiene management device 1 or hygiene management system S to manage the second comparison result as a history of hygiene status that does not depend on human input. By checking the second comparison result, the administrator can confirm the high probability that the user did not touch unnecessary areas with their bare hands during handwashing.
[0121] As described above, the hygiene management device 1 or the hygiene management system S can save images related to the hygiene status of the user's hands to the NVM23 as the user's history. As a result, the hygiene management device 1 or the hygiene management system S can manage a history of hygiene conditions that does not depend on human input. The administrator can use this history of hygiene conditions, which does not depend on human input, as subjective evidence that good hygiene conditions are being maintained.
