  The autonomic nerve analysis unit 4a analyzes the function of the operator's autonomic nerve from the blood flow data of the capillary blood vessels of the fingertip obtained from the fingertip pulse wave sensor 1, and generates autonomic nerve activity data. The outward degree determination unit 4b acquires the autonomic nerve activity data from the autonomic nerve analysis unit 4a, and sets an outward degree that is an index indicating whether the worker is in an outward state or an inward state at the present time. judge. In the present embodiment, a state where the degree of outward is high is suitable for speech and information transmission such as a meeting, and a state where the degree of outward is low (the degree of outward is high) is suitable for office work or the like at his / her own seat. It is judged that. The stress level determination unit 4c acquires the autonomic nerve activity data from the autonomic nerve analysis unit 4a, and determines the stress level, which is the level of stress felt by the worker. In the present embodiment, a state with a high degree of stress is determined as a concentrated state, and a state with a low degree of stress is determined as a relaxed state.

  The business support information generation unit 4d compares the input work schedule with the current work mode based on the data acquired from the outward degree determination unit 4b and the stress degree determination unit 4c (business support information). Is generated. This work support information includes recommended actions such as stretching to promote health, recommended meal information, and recommended environment for work (eg chair height, lighting, room temperature, etc.) Contains information about. Furthermore, the business support information generation unit 4d controls the display unit 5 and the illumination 6 based on the business support information. The physical fatigue level determination unit 4e determines the physical fatigue level based on the measurement data acquired from the physical activity amount measurement unit 2.

  The display unit 5 is a monitor that displays business support information based on an instruction from the calculation unit 4. The illumination 6 is illumination provided in a work space where an operator works, and changes brightness and color tone based on a lighting signal input from the calculation unit 4.

In addition, the display part 5, the illumination 6, and the speaker 7 are equivalent to the provision means in this invention.

  Next, the operation of the business support system A according to this embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is a flowchart showing the operation of the business support system A according to the present embodiment. FIG. 4 is a schematic diagram illustrating an example of a screen displayed on the display unit 5.

  When the business support system A starts operating, the calculation unit 4 displays a work schedule input screen on the display unit 5 (step S1). In other words, the display unit 5 displays, for example, options such as the type of scheduled business, the time to perform the business, the place (self-seat, outing, conference room, etc.), and the operator operates the operation unit 3. Specify one of the options. At this time, it is also possible to obtain automatically from a schedule registered in an intranet or the like.

  In step S1, the work schedule input screen includes an item “Skip work schedule input”, and the operator can execute the job support system A without inputting the work schedule. Next, the calculation unit 4 determines whether or not the work schedule input has been completed (step S2). Here, when the input of the work schedule is not completed, that is, when the determination in step S2 is “NO”, the calculation unit 4 performs the process of step S1 again to display the work schedule input screen. To display.

  When the input of the work schedule is completed, that is, when the determination in step S2 is “YES”, the calculation unit 4 determines whether there is an input of a finger plethysmogram (step S3). That is, the calculation part 4 acquires a detection signal from the finger plethysmogram sensor 1 as a process regarding the autonomic nerve analysis part 4a, and determines whether the finger plethysmogram is measured based on the detection signal. Here, when there is no input of the finger plethysmogram, that is, when the determination in step S3 is “NO”, the calculation unit 4 continues to perform the process of step S3.

  When there is an input of a finger plethysmogram, that is, when the determination in step S3 is “YES”, the calculation unit 4 determines the stress level (step S4). That is, the calculation unit 4 analyzes the autonomic nerve activity based on the fingertip pulse wave acquired from the fingertip pulse wave sensor 1 as a process related to the autonomic nerve analysis unit 4a, and generates autonomic nerve activity data. Furthermore, the calculation part 4 acquires the said autonomic nerve activity data from the autonomic nerve analysis part 4a as a process regarding the stress degree determination part 4c, and determines a worker's stress degree. Next, the computing unit 4 determines the outward degree (step S5). That is, the calculation part 4 acquires the autonomic nerve activity data from the autonomic nerve analysis part 4a as a process regarding the outward degree determination part 4b, and determines the outward degree.

  Subsequently, the calculation unit 4 acquires the amount of physical activity (step S6) and determines the degree of fatigue of the body (step S7). That is, the calculation unit 4 acquires the amount of physical activity from the physical activity amount measurement unit 2 as processing related to the physical fatigue level determination unit 4e, and determines the body fatigue level of the worker based on the amount of physical activity. Next, the calculating part 4 displays the determination result (step S8). That is, as a process related to the work support information generation unit 4d, the calculation unit 4 causes the display unit 5 to display a graph with the stress level as the horizontal axis and the outward degree as the vertical axis, as shown in FIG. Moreover, the calculation part 4 displays on the graph of FIG. 4 the outward degree and stress degree optimal for the input work schedule as a process regarding the work support information generation part 4d. Furthermore, the calculating part 4 displays the determination result of the physical fatigue degree determination part 4e on the screen of FIG.

  Next, the computing unit 4 generates business support information (step S9) and displays it on the display unit 5. That is, as a process related to the work support information generation unit 4d, the calculation unit 4 compares the current outward degree and the stress degree with the optimum outward degree and the stress degree in the work schedule, and improves or decreases the outward degree and the stress degree. Business support information to generate The business support information includes information on actions such as stretching and meals. In the case where the work schedule is not input, for example, the present outgoing degree and stress degree are generally compared with the optimum outward degree and stress degree, and information necessary for obtaining the optimum state is obtained. Generated as business support information. Further, the calculation unit 4 causes the display unit 5 to display the business support information as processing related to the business support information generation unit 4d.

  Next, the computing unit 4 displays a selection screen as to whether or not to adjust the environment on the display unit 5 (step S11). When the operator operates the operation unit 3 and selects “Adjust the environment”, that is, when the determination in step S11 is “YES”, the calculation unit 4 changes the illumination and BGM of the work space (step S11). S12) All the processes are terminated. That is, the calculation unit 4 operates the illumination 6 and the speaker 7 based on the generated business support information as a process related to the business support information generation unit 4d. When the worker selects “Do not adjust environment”, that is, when the determination in step S11 is “NO”, the calculation unit 4 ends all the processes without performing the process of step 12.
