Description

  The present invention relates to a stress notification system and a program.

  The purpose of health management is to increase profitability by preventing or eliminating sick employment (presentism). Sick employment is a state in which productivity has declined due to health problems, although it has not resulted in absence from work. Of the total cost related to health, the direct cost of medical costs and drug costs is about 40% to 70%, and the rest is the loss of labor productivity (indirect costs). Among the indirect costs, there are many studies where the highest cost is sick employment.

Let's consider the causes to prevent and eliminate sick employment. Causes of sick employment include the following.
・ Motor organs, sensory organ disorders, mental health problems, psychosomatic disorders

  Let's consider mental health problems. The stress check has been mandatory from December 2015 by the Ministry of Health, Labor and Welfare once a year. The purpose of this stress check is to prevent mental health problems from occurring. Generally, stress check questionnaires are not frequently performed because the burden of time on the subject is large. Therefore, if there is sick employment during the questionnaire implementation period, no sick employment is detected, so no countermeasure is taken.

  A technique for measuring stress is also known. For example, just by inserting your index finger into the left and right holes of a handheld device, the heart rate variability, sympathetic / parasympathetic balance from the electrocardiogram and pulse wave are displayed as numerical values and graphs. ”And a fatigue / stress measurement system that is notified to a management department is known (see Patent Document 1).

  Also, an image forming apparatus is known in which a user wears a measuring device connected to a main body in response to an operation from the user during printing waiting time, and the user's health data is measured by the measuring device (patent) Reference 2). In this image forming apparatus, the measurement frequency is improved by displaying the measurement promotion information on the display unit.

  In addition, when biological information such as heart rate and sweating status is acquired at a given timing during driving route guidance, if the vehicle deviates from the driving route being guided, is the driver's intention or wrong? There is known a navigation device that determines a change from a change in biological information (see Patent Document 3). If it is erroneously determined that the driver has deviated from the driving route, the driver may be mentally upset. Re-search in favor of routes with experience.

  In addition, the wearable biological information sensor unit that is worn on the body and acquires the biological information of the user, the behavior information sensor unit that acquires the behavior information, the behavior information acquired by the behavior information sensor unit, and the biological information sensor unit are acquired. Information for recognizing the user's situation based on the biometric information, information retrieval means for retrieving information on the stress situation corresponding to the recognized situation as a key, and information for presenting the retrieved advertisement information to the user There has been known a life support device including a presentation means (see Patent Document 4).

  However, in the conventional fatigue / stress measurement system described above, the threshold set for each age is set in the system, and “normal”, “caution”, and “caution” are judged. Since it differs depending on the measurer himself or the environment in which the measurer is placed, there is a risk that accurate fatigue / stress results may not be obtained.

  Further, in the conventional image forming apparatus, since the biological information varies depending on the measurer himself or the environment where the measurer is placed, there is a possibility that an accurate health condition result cannot be obtained.

  Further, in the conventional navigation device, since it is determined whether the off-route is the driver's intention or error based only on the biological information, there is a possibility that an accurate determination result cannot be obtained.

  Further, in the conventional life support system, since the stress state is determined only from the biological information and the behavior information acquired from the device attached to the body, there is a possibility that an accurate stress state cannot be obtained.

(SN) may be used, or a network connection using a uniquely defined protocol may be used, and information such as file sharing on the FTP server may be exchanged using FTP (File Transfer Protocol). It may be a network connection.

  The server 30A is a location management server that manages location information of devices such as the PC 10A. For this reason, the server 30A is installed in a place other than the place (room) where the PC 10A is placed, but may be installed in the same place as the PC 10A. The server 30A and the PC 10A are connected to each other via a wired LAN, but the present invention is not limited to this. The communication connection between the server 30A and the PC 10A can have the same configuration as the communication connection between the PC 10A and the sphygmomanometer 20A.

  Further, it is assumed that a wireless LAN access point is installed in and around a room for measuring a user's blood pressure, and the PC 10A placed in the room can receive radio waves from each access point.

Will be described.

  The control unit 31 controls each unit of the server 30A. The storage unit 33 stores a measurement location conversion table T30. The measurement location conversion table T30 is a table in which the identification information of each access point at which the PC 10A receives radio waves by the wireless communication unit 16, the information on the strength of the radio waves, and the location information on the reception position of the radio waves are associated with each other. .

  Next, information stored in the storage unit 13 of the PC 10A will be described with reference to FIGS. 4 (a) and 4 (b). FIG. 4A shows the stress level conversion table T10. FIG. 4B shows a blood pressure value history table T20.

  The stress level conversion table T10 stored in the storage unit 13 is a table for converting blood pressure values into stress levels. As shown in FIG. 4A, the stress level conversion table T10 has items of blood pressure values T11 and T12 and a stress level T13. The blood pressure value T11 is a blood pressure value when the location information on the blood pressure measurement location of the user is a health care room. The blood pressure value T12 is a blood pressure value when the location information on the blood pressure measurement location of the user is a room. The stress level T13 is a stress level corresponding to the blood pressure values T11 and T12, and the higher the value, the greater the degree of stress.

  Regarding blood pressure, white coat hypertension is known. For example, blood pressure may increase in hospitals. For this reason, since the blood pressure value also changes at each measurement location, two items of blood pressure values T11 and T12 are prepared.

  The blood pressure value history table T20 stored in the storage unit 13 is a history table that stores blood pressure values measured in the past of the user. As shown in FIG. 4B, the blood pressure value history table T20 has items of a measurement date T21, location information T22, and a blood pressure value T23. The measurement date T21 is date / time (year / month / day) information on the blood pressure value of the user. The location information T22 is information on the measurement location corresponding to the measurement date T21. The blood pressure value T23 is a measured blood pressure value [mmHg] corresponding to the measurement date T21.

  Next, the operation of the stress display system 1 will be described with reference to FIGS. FIG. 5 is a flowchart showing the first stress display process. FIG. 6 is a diagram illustrating an example of a stress level graph.

  With reference to FIG. 5, the first stress display process executed by the PC 10A will be described. It is assumed that the PC 10A and the sphygmomanometer 20A are placed in a measurement place where the blood pressure is measured in advance, and the user goes to the measurement place and measures the blood pressure value with the sphygmomanometer 20A. In the PC 10A, for example, when the execution instruction of the first stress display process is input from the user via the operation unit 12, the control unit 11 executes the first stress display process according to the first stress display program PR1. To do.

  As shown in FIG. 5, first, the control unit 11 receives and acquires the measured blood pressure value of the user from the sphygmomanometer 20A (step S11). And the control part 11 receives the electromagnetic wave from each access point of wireless LAN (Wi-Fi) via the wireless communication part 16, acquires the identification information and electromagnetic wave intensity | strength of each access point from the received electromagnetic wave, wired The acquired identification information and radio wave intensity of each access point are transmitted to the server 30A via the communication unit 15 (step S12). Corresponding to step S12, the control unit 31 of the server 30A receives the identification information and radio wave intensity of each access point via the communication unit 35, and uses the measurement location conversion table T30 stored in the storage unit 33. The location information of the room where the transmission source PC 10A is placed is acquired from the identification information and the radio wave intensity of each access point, and is transmitted to the PC 10A.

  And the control part 11 receives the location information of the room (PC10A) in which the blood pressure was measured from the server 30A via the wired communication part 15 (step S13). And the control part 11 uses the stress level conversion table T10 memorize | stored in the memory | storage part 13, and respond | corresponds to the location information received by step S13, and the present stress level from the blood pressure value T11 or T12 received by step S11. T13 is acquired (step S14).

  And the control part 11 reads the blood pressure value history table T20 memorize | stored in the memory | storage part 13, and respond | corresponds to the location information T22 and blood pressure value T23 which were measured in the past using the blood pressure value history table T20 and the stress level conversion table T10. The past stress level T13 is acquired from the blood pressure values T11 and T12 to be performed (step S15). Then, the control unit 11 acquires current date information from a timekeeping unit (not shown) inside the PC 10A, and uses the current date information, the location information acquired in step S13, and the blood pressure value acquired in step S11 as the blood pressure value. The measurement date T21, location information T22, and blood pressure value T23 in the history table T20 are stored as new records (step S16).

  And the control part 11 produces | generates stress display information from the present stress level and measurement date acquired by step S14, and the past stress level and measurement date acquired by step S15, and displays them on the display part 14 (step) (step S14). S17), the first stress display process is terminated.

  In step S17, for example, a stress level graph for a predetermined period (one week) shown in FIG. 6 is displayed as the stress display information. In the stress level graph, the horizontal axis represents time (the number of days elapsed with the date one week before as 1), and the vertical axis represents the stress level.

  As described above, according to the present embodiment, the stress display system 1 includes the sphygmomanometer 20A that measures the blood pressure value as the biological information of the user and the location information of the measurement location as auxiliary information for generating the stress level. Is obtained from the server 30A outside the stress display system 1, and based on the acquired blood pressure value and auxiliary information, a stress level is generated, and the generated stress level is displayed on the display unit 14 PC 10A (control Part 11). For this reason, by using the location information of the measurement in addition to the blood pressure value, an accurate stress level can be acquired and appropriate measures against stress can be taken.

  In addition, the control unit 11 stores the blood pressure value as the measured biological information in the storage unit 13, and based on the stored plurality of blood pressure values and the location information of the measurement location, the history information of the plurality of stress levels is stored. The generated stress level history information is displayed on the display unit 14. For this reason, the history information of the stress level can be easily recognized, and the stress level over time can be obtained.

  In addition, the control unit 11 receives and acquires measurement location information from an external server 30A connected via a communication network. For this reason, measurement location information as auxiliary information can be easily obtained by reception.

  In the above configuration, the location information of the PC 10A is acquired from the server 30A by using the radio wave intensity of the wireless LAN. However, the configuration is not limited to this. For example, the PC 10A includes a satellite positioning unit such as GPS (Global Positioning System), transmits the obtained latitude / longitude information to the server 30A, acquires the location information corresponding to the latitude / longitude information received by the server 30A, and sends it to the PC 10A. It is good also as a structure which transmits. Alternatively, the PC 10A may receive the input of the user ID and transmit it to the server 30A, and the server 30A may acquire the location information of the current location of the user of the user ID received and transmit it to the PC 10A. In this configuration, for example, the server 30A collects the entry / exit information of each room by the IC tag possessed by the user of the user ID and acquires the current location information. Further, the PC 10A may be fixedly installed in the room, the unique ID of the PC 10A may be transmitted to the server 30A, and the location information of the installation location corresponding to the unique ID received by the server 30A may be acquired and transmitted to the PC 10A. .

  In the above configuration, the PC 10A stores the blood pressure value history table T20 and acquires the past stress level each time. However, the configuration is not limited thereto. For example, the control unit 11 of the PC 10A may be configured to store the stress level acquired in step S14 in the stress level history table in association with the measurement date and store it in the storage unit 13. The past stress level can be acquired simply by reading from the stress level history table. According to this configuration, the processing load for generating the stress level can be reduced, the history information of the stress level can be easily recognized, and the stress level over time can be obtained.

After the primary transfer of each color, the toner of each color is removed from the photosensitive drum by the cleaning unit for each color. The color toner images on the intermediate transfer belt are collectively transferred onto the paper conveyed by the paper feeding unit 47 by the secondary transfer roller (secondary transfer).

  The fixing unit heats and presses the paper on which the toner image is formed in accordance with an instruction from the control unit 41 to fix the toner image on the paper. The fixing unit includes, for example, a heating roller that is heated by induction heating or a halogen heater, and a pressure roller that forms a nip portion between the heating roller. Note that the image forming unit 48 may be configured to form a monochrome image on paper, or may be of another image forming method such as an ink jet method.

  The authentication input unit 49 is an input unit for card information stored in a unique ID card possessed by each user, and outputs the read card information to the control unit 41. The control unit 41 can perform user login authentication using the input card information and the authentication table T40 stored in the storage unit 43.

  Here, the authentication input unit 49 reads the card information of the ID card and the control unit 41 performs card authentication. However, the present invention is not limited to this. The authentication input unit 49 may be configured to accept biometric information such as a fingerprint, a face, and an iris and perform biometric authentication. The authentication input unit 49 is included in the operation unit 42, and the operation unit 42 receives a password from the user. A configuration may be adopted in which input of secret information is accepted and authentication is performed using the secret information. Further, a table of user IDs stored in the storage unit 43 and identification information (card information, biometric information, passwords, etc.) is stored in the server 30B, and the control unit 41 passes the communication unit 45 through the table. May be appropriately received from the server 30B and used.

  The server 30B has the same configuration as that of the server 30A in FIG. 3, and only the parts different from the server 30A will be described. The control unit 31 of the server 30B controls each unit of the server 30B. The storage unit 33 stores a stress display program, a stress level conversion table T50, and a stress addition value table T60, which will be described later. The communication unit 35 communicates with the image forming apparatus 40.

  Next, information stored in the server 30B will be described with reference to FIGS. 9 (a) and 9 (b). FIG. 9A shows the stress level conversion table T50. FIG. 9B shows the stress addition value table T60.

  The stress level conversion table T50 is a table for converting blood pressure values and heart rate values into stress levels. As shown in FIG. 9A, the stress level conversion table T50 has items of a blood pressure value T51, a heart rate value T52, and a stress level T53. The blood pressure value T51 is in the range of the blood pressure value [mmHg]. The heart rate value T52 is a range of the heart rate value [bpm]. The stress level T53 is a stress level corresponding to the blood pressure value T51 and the heart rate value T52.

  The stress addition value table T60 is a table for setting an addition value of a stress level for taking into account working hours. As shown in FIG. 9B, the stress addition value table T60 has items of working hours T61 and addition values T62. The working time T61 is a user's working time [hour (/ day)]. The added value T62 is an added value of the stress level corresponding to the working time T61.

  Here, the predetermined working time per day as a standard is 8 hours. If the blood pressure or heart rate rises despite not working for the specified working hours, it is assumed that work is difficult due to strong stress, so an additional value is added to the stress level. Is. Since it is assumed that the stress increases as the working hours increase, the added value increases as the working hours increase.

  Next, the operation of the stress display system 2 will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart showing the second stress display process. FIG. 11 is a flowchart showing the stress transmission process.

  First, the second stress display process executed by the image forming apparatus 40 will be described with reference to FIG. The measurement device 20B is carried in advance to a room where the image forming apparatus 40 is installed, and is connected to the image forming apparatus 40 for communication. In the image forming apparatus 40, for example, triggered by the input of the execution instruction of the second stress display process from the user through the operation unit 42, the control unit 41 performs the second stress display according to the second stress display program PR2. Execute the process.

  As shown in FIG. 10, first, the control unit 41 reads an ID card set by the user via the authentication input unit 49 to acquire card information, and uses the acquired card information and the authentication table T40. The user is authenticated by login, and the user ID of the authenticated user is acquired (step S31). Then, the control unit 41 receives, for example, a document set on the document reading unit 46 and a copy instruction input to the operation unit 42 from the user, and the document reading unit 46, the paper feeding unit 47, the image according to the copy instruction. The forming unit 48 is controlled to start the copy process (step S33). The user measures the blood pressure value and the heart rate value with the measuring device 20B during the copy waiting time. Therefore, in step S33, it is preferable that the control unit 41 displays display information for prompting measurement of the blood pressure value and the heart rate value on the display unit 44 during the copy waiting time.

  And the control part 41 acquires the present date information from the time measuring part (not shown) of the image forming apparatus 40, receives the blood pressure value and the heart rate value measured by the user from the measuring device 20B, and acquires the communication part. The acquired current date and time information, blood pressure value, and heart rate value are transmitted to the server 30B via 45 (step S34). And the control part 41 starts a browser using the browser program memorize | stored in the memory | storage part, and accesses the server 30B via the communication part 45 (step S35).

  Then, the control unit 41 receives the stress level for the browser corresponding to the logged-in user (including the current date and time information and the user ID) from the server 30B via the communication unit 45, and the stress level is displayed on the display unit 44. The information is displayed on the browser (step S36), and the second stress display process is terminated. The user visually checks the browser stress level.

  Next, the stress transmission process executed by the server 30B will be described with reference to FIG. The stress transmission process is a process for providing the image forming apparatus 40 with the stress level of the logged-in user. In the server 30B, in response to step S35 of the second stress display process, the start of reception of the current date / time information, the user ID, the blood pressure value, and the heart rate value from the image forming apparatus 40 via the communication unit 35 is set as a trigger. The control unit 31 executes a stress transmission process according to the stress transmission program stored in the storage unit 33.

  First, the control unit 31 completes reception of the current date and time information, user ID, blood pressure value, and heart rate value from the image forming apparatus 40 via the communication unit 35 (step S41). And the control part 31 discriminate | determines whether the blood pressure value received by step S41 is 135 [mmHg] or more, or the received heart rate value is 100 [bpm] or more (step S42).

  When the blood pressure value is 135 [mmHg] or more or the heart rate value is 100 [bpm] or more (step S42; YES), the control unit 31 obtains the user ID and current date / time information of the logged-in user via the communication unit 35. The information is transmitted to a working time management server (not shown), and for example, the working time nearest to the current date and time information corresponding to the user ID is received from the working time management server (step S43). The working time management server is a server that manages the working time of the user corresponding to each user ID, and provides working time in response to a request from the PC 10B or the like. In step S43, the control unit 41 further corresponds to the received blood pressure value T51 and heart rate value T52 from the blood pressure value and heart rate value received in step S41 and the stress level conversion table T50 stored in the storage unit 43. The acquired stress level T53 is acquired, and from the received working time and the stress added value table T60 stored in the storage unit 43, the added value T62 corresponding to the received working time T61 is acquired, and the acquired stress level is set. The added value is added to determine the final stress level corresponding to the user ID and the current date and time information. For example, when the blood pressure value is 140 [mmHg], the heart rate value is 80 [bpm], and the working time is 12 [hours], the stress level is 2 + added value 1 = 3.

  When the blood pressure value is 135 [mmHg] or more or the heart rate value is not 100 [bpm] or more (step S42; NO), the control unit 41 is stored in the blood pressure value, heart rate and storage unit 43 received in step S41. A stress level T53 corresponding to the received blood pressure value T51 and heart rate value T52 is acquired from the stress level conversion table T50, and determined as a final stress level corresponding to the user ID and current date and time information (step S44).

  And the control part 41 respond | corresponds to step S36 of a 2nd stress display process, the stress level for browsers containing the present date information received by step S41, user ID, and the stress level determined by step S43 or S44. Is created, and the browser stress level is transmitted to the image forming apparatus 40 via the communication unit 45 (step S45), and the stress transmission process is terminated.

  As described above, according to the present embodiment, the stress display system 2 includes the image forming apparatus 40 that forms an image on a sheet. The measurement device 20 </ b> B measures the blood pressure value and the heart rate value as the biological information of the user during the image formation waiting time of the image forming apparatus 40. For this reason, the waiting time for image formation can be used effectively for measuring blood pressure values and heart rate values.

  In addition, the control unit 31 of the server 30B performs labor as auxiliary information when the blood pressure value is equal to or higher than a predetermined threshold (135 [mmHg]) or the heart rate is equal to or higher than a predetermined threshold (100 [bpm]). Obtain time from an external working time management server. For this reason, when the blood pressure value or heart rate value is high and it is assumed that there is a stress load, the stress level can be obtained more accurately by using working time in addition to the blood pressure value and heart rate value, and the detailed stress level Can be analyzed.

  The configuration is not limited to the above. The stress display system 2 includes a PC that is communicatively connected to the image forming apparatus 40 and the server 30B. The PC receives a user ID, current date and time information, a measured blood pressure value, and a heart rate value from the image forming apparatus 40. The stress level may be transmitted to the server 30B and received from the server 30B and displayed.

  In addition, the timing for measuring the blood pressure value and the heart rate value may be during the discharge of the paper on which the printout operation has been performed. In the stress display system 2, the image forming apparatus 40 and the server 30B may be configured as edge servers stored in the same casing. Further, the working time for determining the added value may be a difference between the working time of the past week (average value thereof) based on the history, for example, the current date and time information, and the working time of the previous day.

The belonging group T73 is an in-company group to which the user with the user ID T71 belongs. The affiliation length flag T74 is flag information indicating whether the user of the user ID T71 is the affiliation length of the affiliation group T73 (ON or OFF). The mail address T75 is set only when the affiliation length flag T74 is on (affiliation length), and is the mail address of the user with the user ID T71.

  Next, the operation of the stress display system 3 will be described with reference to FIGS. FIG. 15 is a flowchart showing the stress determination process. FIG. 16 is a flowchart showing the stress providing process. FIG. 17 is a flowchart showing the third stress display process. FIG. 18A shows a group stress display screen. FIG. 18B is a diagram showing a stress distribution display screen.

  First, with reference to FIG. 15, the stress determination process executed by the server 30C will be described. In advance, the control unit 21 of the wearable device 20C is attached to a user in a room of a predetermined company, and in response to a measurement instruction input from the user via the operation unit 22, the biological information measurement unit 26 uses the heartbeat as the user's biological information. The current date and time information obtained from the timekeeping unit (not shown) of the wearable device 20C and the user ID stored in the storage unit 23. At the same time, it is transmitted to the server 30C.

  In the server 30C, for example, the control unit 31 executes a stress determination process according to the stress determination program, triggered by the start of reception of the user ID, current date / time information, and biological information from the wearable device 20C via the communication unit 35. .

  As shown in FIG. 15, first, the control unit 31 completes reception of the user ID, current date information, and biological information from the wearable device 20C via the communication unit 35 (step S51). And the control part 31 sets the unacquired acquisition information of the next order | rank according to the predetermined order of acquisition (step S52). It is assumed that a plurality of external information servers (not shown) for managing acquired information used for acquiring a stress level are provided on a wired LAN connected to the server 30C. The contents of the acquired information are as follows, for example.

(1) Working hours for each individual <Working hours>.
(2) Working hours for each group.
(3) Log of information processing apparatus used for desk work. Specifically, it includes the following: <Information processing log>.
(3-A) Number of key strokes on PC10C,
(3-i) PC10C foreground application type and time,
(3-c) PC10C text input error input number,
(3-d) Number of pages created by the document creation application in the PC 10C,

(5-F) Number of toilets.
(6) Individual attributes. Specifically, <individual attributes> including the following.
(6-A) Age,
(6-I) Sex,
(6-c) Department of affiliation.

  (N (n: natural number)) in the acquisition information indicates the acquisition order. (1) Working hours for each individual and (2) Working hours for each group as the acquired information are acquired from the attendance information management server as an external information server that manages the entrance / exit of the office of a predetermined company using an ID card. . (3) Information processing log as acquired information is an external information server that manages the usage history of PCs, smartphones rented to employees (users) of predetermined companies, and image forming devices installed in the user's room Obtained from the information processing management server.

  (4) Environmental information as acquired information is acquired from an environmental information management server such as a living room as an external information server. (5) Personal information as acquired information includes information (5-a-5-u) collected by a portable information processing device (microphone, acceleration sensor) such as a smartphone possessed by the user, entrance / exit of a dining room and toilet It is acquired from a personal information management server as an external information server that manages history information (5-d to 5-o) and the like. (6) Individual attribute information as acquisition information is acquired from a personnel information management server as an external information server.

For example, the acquisition information is acquired in the following order.
1. Working hours 2. Information processing log Environmental information4. Personal information Personal attributes This ranking is determined from reports of feeling stressed by "a lot of work" and "long working hours" (Hiroki Yasuda, "Changes in Work Environment and Stress-Hope at Work"). This is because the amount of work and working hours are closely related to working hours and closely related to information processing logs. The next most frequently reported cause of stress is the poor work environment, so environmental information is acquired next. This order has an influence when it is determined that information of the next order is not acquired. When only adding to the stress level with auxiliary information, or when the stress level is the maximum at the stage of obtaining working hours, it is not necessary to acquire the acquired information below the information processing log.

  In addition, as acquisition of acquisition information, you may acquire environmental information at the time of the measurement of biometric information first. This is because there is a high possibility that the biological information is changed not by stress but by the environment at the time of measurement.

  And the control part 31 receives the acquisition information of the next order | rank set by step S52 from the external information server via the communication part 35 (step S53). And the control part 31 determines the stress level of the user of user ID from step S53 (step S54). The determination of the stress level may be made with reference to past biological information and stress level history information. For example, when the average of the heart rate values in the past year is 80 [bpm] and this time is 100 [bpm], the stress level may be determined high.

  And the control part 31 discriminate | determines whether the stress level was able to be determined by step S54 (step S55). In step S55, for example, whether or not the stress level can be determined is determined based on whether or not the stress level is finally changed even if further acquired information is used. If the stress level has not been determined (step S55; NO), the process proceeds to step S52. When the stress level is determined (step S55; YES), the control unit 31 stores the stress level determined in step S54 in the storage unit 33 in association with the user ID and current date / time information received in step S51. (Step S56), and the stress determination process is terminated.

  Next, with reference to FIG. 16, a stress providing process executed by the server 30C will be described. In the server 30C, for example, using the power-on as a trigger, the control unit 31 executes a stress providing process according to the stress providing program.

  As shown in FIG. 16, first, the control unit 31 determines whether or not there is an access from the PC 10C via the communication unit 35, for example (step S71). The access from the PC 10C is to receive login information for displaying a stress level from a user as a member other than the head of each group, or to display summary information indicating the stress level of the group from the head of each group. Any one of the received summary link click information for. The summary link is included in a mail addressed to the head of the group, and is link information for displaying the stress level summary information by a click operation. The click information of the summary link includes the user ID of the affiliation manager.

  When there is an access from the PC 10C (step S71; YES), the control unit 31 determines whether or not the access from the PC 10C is click information of the summary link (step S72). When it is not the click information of the summary link (step S72; NO), the access from the PC 10C is the login information reception, and the control unit 31 uses the user ID and password of the login request source user as the login information received in step S71. Using the user information table T70 stored in the storage unit 33, login authentication of the requesting user is performed (step S73).

  And the control part 31 reads the stress level of the latest predetermined period corresponding to user ID from the memory | storage part 33, produces | generates stress level display information from the stress level of a predetermined period, and produces | generates via the communication part 35. The transmitted stress level display information is transmitted to the PC 10C (step S74), and the process proceeds to step S71.

  When it is the summary link click information (step S72; YES), the control unit 31 refers to the user information table T70 stored in the storage unit 33 and is included in the summary link click information received in step S71. Acquires the user ID T71 of the member of the belonging group T73 corresponding to the user ID of the belonging head of the destination of the mail including the summary link, and stores, for example, the stress level of the latest predetermined period corresponding to the belonging head and the user ID of the member The average value of the stress level of all members of the affiliated group and the distribution of the number of members for each stress level of the affiliated group are calculated from the read stress level, and summary information including the calculated information is generated. , Sent to the PC 10C from which the summary link was clicked via the communication unit 35. (Step S75), and transmits to step S71.

  When there is no access from the PC 10C (step S71; NO), the control unit 31 acquires the current date and time information from the time measuring unit (not shown) of the server 30C and determines whether or not the current date and time information is a predetermined time in the morning. (Step S76). The predetermined time in the morning is a time for mail delivery including a summary link for displaying summary information of the group to which the user belongs. When the current date and time information is not a predetermined time in the morning (step S76; NO), the process proceeds to step S71.

  When the current date and time information is a predetermined time in the morning (step S76; YES), the control unit 31 refers to the user information table T70 and generates a summary link including the user ID T71 of the affiliation head of each affiliation group T73 (step S76). S77). And the control part 31 transmits the mail containing the summary link produced | generated by step S77 to the mail address T75 of the affiliation head of each affiliation group T73 via the communication part 35 (step S78), and goes to step S71 Transition.

  Next, the third stress display process executed by the PC 10C will be described with reference to FIGS. In the PC 10C, for example, the control unit 11 executes the third stress display process according to the third stress display program, triggered by the input of the execution instruction of the third stress display process from the user via the operation unit 12, for example. .

  As shown in FIG. 17, first, the control unit 11 determines whether or not there is a click input of the summary link after opening the mail when the user is the head of the affiliation via the operation unit 12 (step) S81). When there is no click input of the summary link (step S81; NO), the control unit 11 accepts input of a user ID and password as login information from the user via the operation unit 12, and corresponds to step S71 of the stress providing process. Then, the input user ID and password are transmitted to the server 30C via the wired communication unit 15 (step S82). In response to step S74 of the stress providing process, the control unit 11 receives the display stress level from the server 30C via the wired communication unit 15 and displays it on the display unit 14 (step S83). 3 The stress display process is terminated. In step S83, for example, as shown in FIG. 6, a graph of the stress level for a predetermined period (for one week) corresponding to the login user is displayed.

  When there is a click input of the summary link (step S81; YES), the control unit 11 receives summary information from the server 30C via the wired communication unit 15 and displays the display unit corresponding to step S75 of the stress providing process. 14 (step S84), and the third stress display process is terminated. In step S84, for example, a group stress display screen showing the average stress level of all members of the group belonging to the affiliation head shown in FIG. And a stress distribution display screen showing the distribution of the number of members.

  As described above, according to the present embodiment, the control unit 31 of the server 30C stores the generated stress level in the storage unit 33 in association with the user ID. The control unit 11 of the PC 10 </ b> C causes the display unit 14 to display the stress level history information for each user stored in the storage unit 33. For this reason, the history information of the stress level for each user can be easily recognized, and the stress level over time can be obtained.

  In addition, the control unit 31 stores the generated stress level in the storage unit 33 in association with the user ID and the identification information of the belonging group. The control unit 11 causes the display unit 14 to display the history information of the stress level for each belonging group stored in the storage unit 33. Therefore, it is possible to easily recognize the stress level history information for each user and the group to which the user belongs and to obtain the stress level over time.

  The biometric information includes at least one of a blood pressure value, a heart rate value, the number of blinks, a shallowness of breathing, a body temperature, a voice pitch, a speaking method, an electroencephalogram, and a sweating amount. For this reason, a more accurate stress level can be obtained from various biological information closely related to stress.

  The auxiliary information includes user action history information. The action history information includes at least one of the user's working hours and the user's usage history information (information processing log). For this reason, it is possible to obtain a more accurate stress level by using working hours and information processing logs that are closely related to stress as user behavior history information.

  Further, the action history information includes at least one of the number of times the user speaks himself, the number of times the word is not suitable for the office, the number of steps per day, the number of times of running, and the number of times of toilets. For this reason, a more accurate stress level can be obtained from various action history information closely related to stress.

  Further, the auxiliary information includes environmental information on the measurement location of the biological information. For this reason, a more accurate stress level can be obtained from the environmental information of the measurement place that is closely related to stress.

  The auxiliary information includes the user's personal attributes. For this reason, a more accurate stress level can be obtained from the personal attributes of the user who are closely related to stress.

  Moreover, the control part 11 acquires as a supplementary information in order of a user's action history information, environmental information, and a personal attribute. For this reason, an accurate stress level can be obtained by using auxiliary information in descending order of contribution to the stress level.

  Further, the control unit 11 uses the acquired auxiliary information (acquired information) to further determine the stress level when the stress level can be finally determined (the stress level does not change even if auxiliary information is used further). Information (acquisition information) is not acquired. For this reason, it is possible to obtain an accurate stress level by using auxiliary information in descending order of contribution to the stress level, and it is possible to shorten a time until the stress level is obtained.
