The light-emitting section main body 3 includes a central light source 5 and an ambient light source 6 for making the brightness around the central light constant. . Furthermore, 7 is a position measuring device for measuring the position of the subject A, and optically measures the distance to both eyes of the subject A. In addition, an orientation / height adjustment device 8 that obtains information from the position measurement device 7 and automatically adjusts the height H and the orientation θ of the light emitting unit main body 3 with respect to both eyes of the subject A is provided. .

  Here, the direction of the subject A is determined by measuring the position of both eyes of the subject A with an optical distance sensor (pupil sensor) through the light shielding tube 4 and detecting the direction θ, and the direction θ is made constant. In this state, the height H of the light emitting unit main body 3 that matches the eyes of the subject A can be obtained, and the light emitting unit main body 3 can be automatically set to the position of the optimal direction and height of the light emitting unit main body 3. That is, the light emitting unit main body 3 has a swing function, and can face the subject A's face and the central light in front of each other. Therefore, when the subject A sits on a chair (for example, a simulated vehicle driver's seat) B, the orientation of the light-emitting unit main body 3 having the light-shielding tube 4 so as to adapt to both eyes of the subject (driver) A Automatic height adjustment can be performed.

  Reference numeral 9 denotes a seating sensor, which detects when the subject A is seated on the chair B and can automatically drive the flicker measuring apparatus.

  In addition, since the ambient light source 6 is provided at four locations, the brightness around the central light is kept uniform.

  Reference numeral 24 denotes an operation button. When the subject A can stand by, the flicker measurement device can be manually driven by operating the operation button 24.

  Furthermore, an information processing device (personal computer) 11 having a display device 21 is connected to the base 1. The information processing apparatus 11 includes an input interface 12, a CPU (central processing unit) 13, a first storage device 14 that stores measurement values for each measurement by the flicker measurement device, and a second storage that accumulates past flicker values. Storage device 15, display device 21 connected via output interface 16, third storage device 17 for storing overwork warning values, warning device 22 connected to output interface 18, subject A remote switch 23 , An operation button 24 connected to the output interface 19, and a fourth storage device 25. In addition, although it mentions later, when the remarkable change is seen in fatigue, the candidate which becomes the cause is displayed on the display part 21A in the display apparatus 21. FIG.

  As described above, the information processing apparatus 11 includes the first storage device 14 that stores the flicker values measured by the flicker measuring device and the second storage device 15 that accumulates and stores past flicker values. The information stored in the storage devices 14 and 15 is displayed on the display device 21 via the output interface 16. That is, the display device 21 displays the flicker value at the time of measurement by the flicker measurement device quickly and accurately, and displays the past measurement value and the current fatigue level of the subject A in comparison. In that case, the change of the fatigue level from the weekly unit to the month or several years is tracked and displayed.

  FIG. 3 is a diagram showing a change in the degree of fatigue based on the flicker value displayed on the display device according to the embodiment of the present invention.

  In this figure, the horizontal axis is the elapsed date and time, and the vertical axis is the flicker value change (%) indicating the change in fatigue level.

  The change of fatigue level here is monitored over a long period of time, 1 week (1W), 2 weeks (2W), 1 month (1M), or 1 year, to monitor whether the fatigue is changed to serious overwork. I am doing so.

  In addition, the information processing apparatus 11 includes a third storage device 16 that stores an overwork warning value. When the measured value exceeds the warning value of the third storage device 16, the warning device 22 is output via the output interface 18. The warning is made by.

  Further, when the flicker value by the flicker measuring device is lowered, the cause is searched. The subject A presses the operation button 24 serving as a cause search button, and checks an item estimated to be the cause. For example, the items that are presumed to be the cause are “(1) Late night work, (2) Trouble at work, (3) Trouble at home, (4) Deep alcohol, (5) Cold, (5) Hay fever, Items such as (6) high blood pressure, (7) palpitation, (8) overtime of ○ to ○ hours, (9) overtime over ○ hours ”are sequentially displayed on the display device 21, so the corresponding items are If there is, it is stored in the storage device 24 as a corresponding item.

  In this way, when the flicker value is significantly decreased, that is, when the fatigue level is significantly increased, the cause is also searched.

  On the contrary, when the flicker value is remarkably recovered, the item presumed to be the cause is checked. For example, items that are presumed to be the cause include “(1) Day off, (2) Deep sleep due to exercise, (3) Solutions for each problem, (4) Unexpected salary increase, (5) Shortened overtime hours”, etc. Can be mentioned.

  In this way, even when the flicker value is significantly recovered, that is, when the fatigue level is significantly reduced, the cause is also searched.

  By doing so, it is possible to prevent overwork by clearly searching for the cause of the flicker value being reduced and removing the cause.

  In addition, it is possible to make a plan for ensuring rest by clearly searching for the cause of the flicker value recovery.
