Description

  The present invention relates to an information processing apparatus, a sleep disorder determination system, a program, and a sleep disorder determination method.

  Traditionally, the human body wakes up in the morning and sleeps at night. However, the number of people who are active at night against this rhythm is increasing, and it is now possible to watch TV and mobile phone displays at any time. As a result, an increasing number of people suffer from circadian rhythm sleep disorders such as sleep phase regression syndrome, which causes poor sleep and chronic sleep delay.

  It is said that if you look at the light from a display such as a TV or mobile phone just before going to bed or at midnight, the light that enters the retina will stimulate the brain and contribute to circadian rhythm sleep disorders. Yes. In particular, it is known that short wavelength light has a function of suppressing melatonin related to sleep, and thus has a great influence on sleep disorders (see, for example, Non-Patent Document 1).

  Thus, for example, Patent Document 1 proposes a device that selectively blocks light having a short wavelength in order to maintain the circadian rhythm of the subject.

However, there has been a need for a device that provides a user with a judgment material for the risk of sleep disorders. .

<Operation of sleep disorder determination system>
Next, operation | movement of the sleep disorder determination system 100 in this embodiment is demonstrated.

(Operation of glasses-type device 1)
First, the operation of the eyeglass-type device 1 will be described.
FIG. 7 shows a flowchart of the light measurement process executed by the glasses-type device 1. The light measurement process is executed by the cooperation of the CPU of the control unit 10 and the program stored in the ROM while the eyeglass-type device 1 is turned on (not shown).

  First, the control unit 10 determines whether it is a data acquisition time based on the time from the time measuring unit 12 (step S1). Here, the spectacle-type device 1 is configured such that the data acquisition time arrives at a predetermined time (for example, every 10 minutes). In the present embodiment, the data acquisition time is the same as the data acquisition time of the wrist terminal 2.

  When it is determined that it is the data acquisition time (step S1; YES), the control unit 10 obtains the measurement result data x1, x2, and x3 of the light intensity of each of the short wavelength, medium wavelength, and long wavelength from the optical sensor 11. Obtain (step S2). For each of the short wavelength, medium wavelength, and long wavelength, the intensity of light from the optical sensor 11 is acquired every predetermined time interval for a predetermined period from the data acquisition time, and the average value is used as measurement result data. Also good.

  Next, the control unit 10 stores the measurement result data in the optical information storage unit 130 of the storage unit 13 in association with the data acquisition time (step S3).

Next, the control unit 10 determines whether it is a data transmission time based on the time from the time measuring unit 12 (step S4). Here, the glasses-type device 1 is set so that the data transmission time arrives at a predetermined time (for example, every two hours from 0:00). In the present embodiment, the data transmission time is the same as the data transmission time of the wrist terminal 2.
When it is determined that it is not the data transmission time (step S4; NO), the control unit 10 returns to the process of step S1.

When it is determined that it is the data transmission time (step S4; YES), the control unit 10 transmits the data written in the optical information storage unit 130 to the portable terminal 3 by the communication unit 14 (step S5), and the storage unit 13 optical information storage units 130 are initialized (step S6), and the process proceeds to step S1.
The control unit 10 repeatedly executes the processes of steps S1 to S6 until the power is turned off.

(Operation of wrist terminal 2)
Next, the operation of the wrist terminal 2 will be described.
In FIG. 8, the flowchart of the sleep information generation process performed by the wrist terminal 2 is shown. The sleep information generation process is executed by the cooperation of the CPU of the control unit 20 and the program stored in the ROM while the wrist terminal 2 is turned on.

  First, the control unit 20 determines whether it is a data acquisition time based on the time from the time measuring unit 23 (step S11).

  When it is determined that it is the data acquisition time (step S11; YES), the control unit 20 acquires acceleration measurement result data from the acceleration sensor 21, and causes the heart rate monitor 22 to measure the heart rate per minute. Measurement result data is acquired (step S12). Note that acceleration measurement result data from the acceleration sensor 21 may be acquired at predetermined time intervals for a predetermined period from the data acquisition time, and the average value may be used as the measurement result data. The heart rate may be averaged over a plurality of data.

  Next, the control unit 20 determines whether the user is sleeping based on the measurement result data acquired from the acceleration sensor 21 and the measurement result data acquired from the heart rate monitor 22 (sleep / wakefulness determination) ( Step S13). Acceleration and heart rate are greater when waking (not sleeping) than when sleeping. Therefore, for example, the acquired acceleration and heart rate are respectively compared with a predetermined threshold value, and if any of them is larger than the threshold value, it is determined that the user is awake (not sleeping). If both are smaller than the threshold, it is determined that the user is sleeping.

  Next, the control unit 20 acquires the current time from the time measuring unit 23, associates the information indicating whether or not sleeping with the determined time, and stores the information as sleep information in the sleep information storage unit 240 of the storage unit 24. (Step S14).

  Next, the control unit 20 determines whether it is a data transmission time based on the time from the time measuring unit 23 (step S15). When determining that it is not the data transmission time (step S15; NO), the control unit 20 returns to the process of step S11.

When it is determined that it is the data transmission time (step S15; YES), the control unit 20 transmits the data written in the sleep information storage unit 240 to the portable terminal 3 by the communication unit 25 (step S16), and sleep information. The storage unit 240 is initialized (step S17), and the process returns to step S11.
The control unit 20 repeatedly executes the processes of steps S11 to S17 until the power is turned off.

(Operation of mobile terminal 3)
Next, the operation of the mobile terminal 3 will be described.
FIG. 9 shows a flowchart of the weighting process executed in the mobile terminal 3. The weighting process is executed in cooperation with the CPU of the control unit 30 and the program stored in the ROM when a predetermined time (for example, data transmission time of the glasses-type device 1 and the wrist terminal 2) has arrived. Is done.

  First, the control unit 30 receives information x1, x2, and x3 indicating the intensity of light in each wavelength band from the glasses-type device 1 through the communication unit 35, and also receives sleep information from the wrist terminal 2 ( Step S21).

  Next, the control unit 30 acquires the sleep rhythm weight γ from the server device 4 via the communication unit 35 (step S22).

  Next, the control unit 30 calculates the average value of the received light intensity x1 of the short wavelength, the average value of the intensity x2 of the medium wavelength light, and the average value of the intensity x3 of the long wavelength light, respectively. The values are x1, x2, and x3, respectively (step S23).

  Next, the control unit 30 determines whether the measurement time zone of the information indicating the received light intensity is daytime or midnight (step S24). Here, it is determined that the time from 4:00 am to 22:00 pm is the daytime and the time from 22:00 pm to 4:00 am is the midnight band. When it is determined that the measurement time zone is daytime (step S24; daytime), the control unit 30 sets the weight α to α <1 (for example, α = 0.8) (step S26), and step S27. Move on to processing. When it is determined that the measurement time zone is midnight (step S24; midnight), the control unit 30 sets the weight α to α> 1 (for example, α = 1.2) (step S25), and step S27. Move on to processing.

In step S27, the control unit 30 calculates y1, y2, and y3 obtained by multiplying x1, x2, and x3 by weights α, β, and γ, respectively (step S27).
The weight α is a weight based on the measurement time zone of the light intensity, and differs depending on whether the measurement time zone is daytime or midnight. Since the late-night light has a great influence on sleep disturbance, the weight α is larger than 1. On the other hand, the light α during the daytime activity has a small influence on the sleep disorder, so the weight α is smaller than 1.
The weight β is a weight based on the wavelength and differs depending on the wavelength band. The short wavelength, medium wavelength, and long wavelength have higher light energy in this order. In addition, it is known that short wavelengths have a function of suppressing melatonin, which is a hormone that induces sleep. Therefore, the short wavelength weight β1> the medium wavelength weight β2> the long wavelength weight β3. Here, β1 = 1.2, β2 = 1, and β3 = 0.8.
The weight γ is a weight based on the sleep rhythm. The weight γ is calculated by a learning process described later in the server device 4. The weight when sleep is regularly taken is γ <1, and the weight when sleep is not taken regularly is γ> 1. ing. The greater the disturbance of sleep rhythm, the greater the value of γ.

  In addition, the weighting based on the weight α according to the time zone and the weight γ according to the sleep rhythm is for making a determination according to the user's situation more. As a simple configuration, the weighting according to the wavelength zone is used. It is good also as weighting only (beta). Alternatively, the weights β and α and the combinations of weights β and γ may be weighted.

  Next, the control unit 30 transmits the user ID, the y value obtained by adding y1, y2, and y3 and the sleep information received from the wrist terminal 2 to the server device 4 through the communication unit 35 (step S28).

  In the server apparatus 4, when the information from the portable terminal 3 is received, the determination process mentioned later is performed and the risk of a user's sleep disorder is determined based on the received information. And the advice information according to the determination result and the determination result is transmitted to the portable terminal 3. The advice information is advice information for suppressing sleep disorders. For example, for users who have a high risk of sleep disorders, advice such as “Stop watching TV and PC screens at night and sleep early” Send information. Advice information such as “Let's take sleep regularly” is transmitted to a user who has a moderate risk of sleep disorders. Advice information such as “Let's continue the life rhythm as it is” is transmitted to the user who is not at risk of sleep disorder.

  When the determination result and advice information from the server device 4 are received by the communication unit 35 (step S29), the control unit 30 displays the determination result and advice information on the display unit 32 (step S30), and ends the weighting process.

(Operation of server device 4)
Next, the operation of the server device 4 will be described.
FIG. 10 shows a flowchart of the determination process executed in the server device 4. The determination process is executed by the cooperation of the CPU of the control unit 40 and the program stored in the ROM when data such as the value of y and sleep rhythm information is received from the portable terminal 3.

  First, the control unit 40 acquires the value of y from the data received from the mobile terminal 3 (step S41), and calculates the value of y / T (step S42). The value of T is a threshold value stored in the threshold value T storage unit 443 of the storage unit 44. Alternatively, the y value for one day or several days corresponding to the received user ID may be read from the reception database 441, and y / T may be calculated with the average value of these y values as y.

  Next, the control unit 40 determines the risk of sleep disorder based on the value of y / T (step S43). Specifically, the control unit 40 refers to the determination table 444 from the storage unit 44, and determines the risk of sleep disorder based on the y / T value. That is, the control unit 40 compares the weighted information y indicating the intensity of light with the value of the threshold value T, and determines the risk of sleep disorder based on the comparison result (y / T).

Next, the control unit 40 reads advice information corresponding to the determined risk from the determination table 444, and transmits the advice information together with the determination result to the mobile terminal 3 that is the data transmission source by the communication unit 45 (step S44). The advice information is advice information for suppressing sleep disorders as described above. If there is no danger, no advice information may be provided.
And the control part 40 adds a record to the reception database 441 of the memory | storage part 44, stores the data received from the portable terminal 3 (step S45), and complete | finishes a determination process.

Next, the learning process executed in the server device 4 will be described.
FIG. 11 shows a flowchart of the learning process executed in the server device 4. The learning process is executed in cooperation with the CPU of the control unit 40 and the program stored in the ROM when a predetermined time has arrived.

  First, the control unit 40 determines, for one user, whether the deviation in the average sleep time period is 2 hours or more or less than 2 hours based on the data stored in the reception database 441 (step S40). S50). That is, a record corresponding to one user ID is extracted from the reception database 441, and based on the extracted data, it is determined whether the deviation of the average sleep time period is 2 hours or more or less than 2 hours. The shift in the average sleep time period refers to a shift in the average sleep time period (for example, the average time period of the last two to three days) from a predetermined optimal sleep time. For example, the optimal sleep time may be set from the mobile terminal 3 for each user, or may be the average sleep time of the last n months (n is a positive number) calculated based on the reception database 441.

  When it is determined that the shift in the average sleep time period is less than 2 hours (step S50; less than 2 hours), the control unit 40 reads the weight γ from the weight γ storage unit 442 and sets γ1 = γ × 0.8. Calculate (step S51), and the process proceeds to step S53. When it is determined that the shift in the average time of sleep is 2 hours or more (step S50; 2 hours or more), the control unit 40 reads the weight γ from the weight γ storage unit 442 and sets γ1 = γ × 1.2. The calculation is performed (step S52), and the process proceeds to step S53. Here, the initial value of the weight γ is 1.

  In step S53, the control unit 40 determines, for the same user, whether the deviation of the average time zone for waking up is 2 hours or more or less than 2 hours based on the data accumulated in the reception database 441 ( Step S53). The deviation of the average time zone of waking up refers to the deviation of the average time zone of waking up from a predetermined optimal waking time (for example, the average time zone of the latest two to three days). For example, the optimal wake-up time may be set from the mobile terminal 3 for each user, or may be an average wake-up time for the past n months (n is a positive number) calculated based on the reception database 441.

  When it is determined that the deviation of the average time zone of waking up is less than 2 hours (step S53; less than 2 hours), the control unit 40 calculates γ2 = γ1 × 0.8 (step S54), and proceeds to step S56. To do. When it is determined that the deviation of the average time zone of waking up is 2 hours or more (step S53; 2 hours or more), the control unit 40 calculates γ2 = γ1 × 1.2 (step S55), and the process of step S56 Migrate to

  In step S <b> 56, the control unit 40 determines that the average frequency of sleep disturbances (nap during the nap) is 3 or more times or less than 3 times for the same user based on the data stored in the reception database 441. It is determined whether or not there is (step S56). For example, the number of times of waking up is the average of the number of times that it was determined that the person did not sleep after being determined to be sleeping in the average sleep time zone calculated from the received data of the past n months (for example, the most recent 2 to 3 Day average). The number of times of napping is the average of the number of times that it was determined to sleep continuously for 30 minutes or more in a predetermined time zone (for example, from 15:00 to 21:00) other than the above-mentioned sleep time zone (for example, the latest 2-3 days) Average). Note that the above-described method of counting sleep disturbance is an example, and the present invention is not limited to this.

  When it is determined that the average frequency of sleep disturbance is less than 3 times (step S56; less than 3 times), the control unit 40 calculates γ3 = γ2 × 0.8 (step S57), and proceeds to step S59. . When it is determined that the average frequency of sleep disturbance is 3 times or more (step S56; 3 times or more), the control unit 40 calculates γ3 = γ2 × 1.2 (step S58), and performs the process of step S59. Transition.

  In step S59, the control unit 40 updates the sleep rhythm weight γ stored in the weight γ storage unit 442 to γ3, and updates the threshold T stored in the threshold T storage unit 443 to T ÷ γ3 ( Step S59).

  Next, the control unit 40 determines whether or not the processing of steps S50 to S59 has been executed for all users, and if it is determined that it has not been executed (step S60; NO), the control unit 40 returns to the processing of step S50. Steps S50 to S59 are executed for the user. When it is determined that the processes in steps S50 to S59 have been executed for all users (step S60; YES), the control unit 40 ends the learning process.

As described above, according to the sleep disorder determination system 100, the control unit 30 of the mobile terminal 3 displays information indicating the intensity of light received by the user measured in the eyeglass-type device 1 for each of a plurality of wavelength bands. The information acquired via the communication unit 35 is weighted according to the wavelength band on the acquired information indicating the light intensity for each wavelength band, and is transmitted to the server device 4 by the communication unit 35. The control unit 40 of the server device 4 determines the risk of the user's sleep disorder based on the information indicating the weighted light intensity, and transmits the risk to the mobile terminal 3 that is the transmission source by the communication unit 45. The control unit 30 of the portable terminal 3 outputs the determination result to the display unit 32 when the communication unit 35 receives the determination result from the server device 4.
Therefore, it is possible to provide the user with a material for determining the risk of sleep disorders.

  The control unit 30 compares the weighted light intensity information with a predetermined threshold value, and determines the risk of the user's sleep disorder based on the comparison result. Therefore, it is possible to easily determine the risk of the user's sleep disorder based on the information indicating the weighted light intensity.

  In addition, the control unit 30 assigns a greater weight to the wavelength band on the short wavelength side than the wavelength band on the long wavelength side. Therefore, since the effect of suppressing melatonin related to sleep is large and a large weight is given to the wavelength band on the short wavelength side where the energy is strong, the risk of sleep disorder can be determined more accurately.

  In addition, the control unit 30 further weights the information indicating the light intensity according to the time period when the information indicating the light intensity is measured. Therefore, it becomes possible to determine the sleep disorder more accurately according to the time zone in which the user was exposed to light.

  Specifically, the control unit 30 assigns a greater weight to the midnight time zone than to the daytime time zone. Therefore, since a large weight is applied to light in the midnight where the influence on the sleep disorder is large, the risk of the sleep disorder can be determined with higher accuracy.

In addition, the control unit 30 acquires sleep information in which information indicating whether or not the user is sleeping and time is associated from the wrist terminal 2 via the communication unit 35, and transmits the sleep information to the server device 4. The control unit 40 of the server device 4 accumulates and stores the sleep information transmitted from the mobile terminal 3 in the reception database 441, and based on the sleep information stored in the reception database 441, assigns a weight according to the user's sleep rhythm. calculate. The control unit 30 of the mobile terminal 3 obtains a weight corresponding to the sleep rhythm from the server device 4 by the communication unit 35, and further weights the information indicating the light intensity using the weight corresponding to the user's sleep rhythm. I do.
Therefore, the risk of sleep disorder can be determined more accurately according to the user's sleep rhythm.

  Specifically, the control unit 40 of the server device 4 calculates the number of times of the user's falling asleep time zone, the rising time zone shift, and the sleep disturbance based on the sleep information stored in the reception database 441. When the number of sleep time periods, waking time period shifts, or sleep disturbances is greater than a predetermined reference, the weight corresponding to the sleep rhythm is increased. Therefore, it becomes possible to make a more accurate determination according to the sleep rhythm of the user.

  Moreover, since the display part 32 of the portable terminal 3 displays the advice information for suppressing a sleep disorder according to a determination result, it becomes possible to provide the advice information for suppressing a sleep disorder to a user.

  In addition, the description content in the said embodiment is a suitable example of the sleep disorder determination system which concerns on this invention, and is not limited to this.

  For example, in the embodiment described above, the portable terminal 3 has an optical information acquisition unit, a sleep information acquisition unit, a weighting unit, and an output unit, and the server device 4 includes a determination unit, a storage unit, and a weight calculation unit. However, a configuration may be adopted in which all means are provided in one information processing apparatus. In this case, a program for causing the computer of the information processing apparatus to function as each of the above means is stored in the storage unit of the information processing apparatus.

  Also, various weights, threshold values, sleep disorder risk determination criteria and advice information are examples, and are not limited to the above embodiment. Further, the output means is not limited to the display unit, and may be output from a printing apparatus or the like.

  Also, as a computer-readable medium storing a program for executing each of the above processes, a non-volatile memory such as a flash memory, a portable recording medium such as a CD-ROM, in addition to a ROM, a hard disk, etc. Is also possible. A carrier wave is also used as a medium for providing program data via a predetermined communication line.

  In addition, the detailed configuration and detailed operation of each device constituting the sleep disorder determination system can be changed as appropriate without departing from the spirit of the invention.
