Description

Sleep improvement support device, organization improvement support device, and program

The present invention relates to a sleep improvement support device, an organization improvement support device, and a program.

Sleep is essential for our activities. It is said that when lack of sleep occurs, immunity and natural healing power decrease, and secretion of growth hormone is also adversely affected. Insufficiency of sleep can also lead to poor quality of life, reduced work performance, and, in more serious cases, mental disorders such as depression. For this reason, the sleep management technique for improving the quality of a user's sleep is proposed (for example, refer patent document 1).

When falling into sleeplessness or lack of sleep, the user's daytime activities are adversely affected. Here, the evaluation of daytime activities and the evaluation of whether or not you can sleep well are also related to how users perceive (recognize). Therefore, there exists a treatment method called “Cognitive 認知 Behavioral Therapy-Insomnia (CBT-i)” for improving insomnia. It is considered that the above-described technology is premised on CBT-i.

JP 2011-36649 A

CBT-i is a therapy for improving insomnia. For example, improvement of sleep quality for a user who is healthy but lacks sleep is not considered. Further, CBT-i derives a countermeasure (behavior) related to improvement of sleep quality based on a sleep tendency for at least about one week. For this reason, for example, information on the latest sleep such as all night on the previous day is difficult to be reflected in the countermeasure. Thus, it is considered that there is room for further improvement in the technology that supports the improvement of sleep quality.

Therefore, the present invention has been made in view of these points, and an object thereof is to provide a technique for supporting improvement of sleep quality.

The first aspect of the present invention is a program.

[First Embodiment]
<Outline of First Embodiment>
The sleep improvement support apparatus according to the first embodiment collects and analyzes time information related to the user's sleep and evaluation related to the user's daytime activity. The sleep improvement support apparatus according to the first embodiment presents information for improving the user's sleep based on the analysis result.

FIG. 1 is a diagram for explaining the outline of the first embodiment, and is a diagram schematically showing the daily activities of the user U on weekdays. In the following, with reference to FIG. 1, the outline of the first embodiment and the preconditions thereof will be described in (1) to (4). The description will be made from (1) to (4) in FIG. And corresponding.

(1) User U goes to bed and eventually falls asleep. Here, “bed” means that the user U falls on the floor, and “sleeping” means that the user U falls asleep. Accordingly, there may be a difference between the bedtime when the user U goes to bed and the sleep time when the user U sleeps.

(2) The user U is awakened and eventually starts to work. Here, “awakening” means that the user U wakes up, and “wakes up (start of activity)” means that the user U gets up from the bed. Therefore, there may be a difference between the awakening time that is the time when the user U has awakened and the wake-up time that is the time when the user U starts the activity (activity start time).

The user U puts the sleep improvement support apparatus 1 on the bedside at bedtime. The sleep improvement support apparatus 1 is, for example, a mobile terminal such as a smartphone or a tablet PC (Personal Computer), and includes at least a sensor such as an acceleration sensor and a microphone, and calculation resources such as a CPU (Central Processing Unit) and a memory. Device. Thereby, the sleep improvement assistance apparatus 1 can measure and analyze the voice generated due to the user U such as sleep and snoring, and the movement of the user U from getting up to getting up.

(3) The user U performs activities such as work during the day.
(4) After completing the activity, the user U who has returned to his / her home has finished eating and bathing, and then goes to bed.

The sleep improvement support apparatus 1 analyzes the information acquired using the acceleration sensor and the microphone using a known algorithm, thereby obtaining time information including the user U's bedtime, sleep time, wake-up time, and wake-up time. Estimate and get. The sleep improvement support device 1 executes software that has executed an algorithm for estimating time information in the background. For this reason, even if the user U does not explicitly operate the sleep improvement support apparatus 1, the sleep improvement support apparatus 1 can automatically estimate and acquire time information every day.

User U inputs an evaluation regarding daytime activity before falling asleep. Although details will be described later, the activity-related evaluation is a subjective evaluation of the user U regarding whether or not he / she was in good condition during the day, and the sleep improvement support apparatus 1 derives information for improving the sleep of the user U. This information is used for this purpose.

The sleep improvement support device 1 has an alarm function used for awakening, and the condition of the alarm set is that the user U inputs an evaluation regarding daytime activities. If it is customary for the user U to use the alarm function for awakening, an evaluation regarding the daytime activity is input to the sleep improvement support device 1 every day in order to set the alarm. Thereby, the sleep improvement assistance apparatus 1 can improve the certainty that the user U inputs the evaluation regarding the activity during the daytime. As a result, the sleep improvement support device 1 can also increase the accuracy of information for improving the sleep of the user U.

The sleep improvement support device 1 calculates the sleep efficiency of the user U based on the estimated time information. Here, sleep efficiency is a percentage of the sum of the difference between “sleeping time and awakening time” for one week with respect to the sum of “difference between bedtime and waking time” for one week. In other words, it is the ratio of the time that the user U was actually sleeping to the time that the user U was in bed for one week.

In the CBT-i framework, sleep efficiency is calculated in units of one week. In the framework of CBT-i, it is considered appropriate that the sleep efficiency is 85% or more. When the sleep efficiency is less than 85%, it means that the user U does not sleep on the floor or wakes up on the way, and insomnia is suspected. On the other hand, if the subjective evaluation for the physical condition during the day is low even if the sleep efficiency exceeds 95%, it is suspected that the user U is short of sleep.

The sleep improvement support apparatus 1 according to the first embodiment also acquires the amount of fluctuation of time information related to the sleep of the user U at an interval shorter than the period used for calculating the sleep efficiency in the CBT-i framework. Specifically, since the period used for calculating the sleep efficiency is one week, the sleep improvement support apparatus 1 calculates the amount of time information fluctuation in an interval shorter than seven days, preferably in units of two or three days. calculate.

Thereby, the sleep improvement support device 1 can detect a change in the sleep of the user U in a period shorter than the period used for calculating the sleep efficiency. As a result, the sleep improvement support device 1 can detect in a short time that the user U has changed sleep rhythm due to circumstances such as staying up all night or traveling overseas.

The sleep improvement support device 1 improves the sleep quality of the user U based on the calculated sleep efficiency, the fluctuation amount of time information in a period shorter than the period used for calculating the sleep efficiency, and the activity evaluation input by the user U. Information to do is selected and presented on the display unit. Here, “sleep quality” is based on at least whether sleep efficiency is appropriate and whether the time from bedtime to wakeup is stable. Specifically, when the sleep efficiency of the user U is 85% or more, the fluctuation amount of the bedtime or the wake-up time is small, and the subjective evaluation for the physical condition during the day is high, the sleep quality of the user U is high. I can say that.

The evaluation of the activity of the user U (for example, the performance of the work of the user U) is considered to be related to the sleep quality of the user U. Although details will be described later, for example, when the evaluation of the activity of the user U is low, the sleep efficiency exceeds 95%, but when the subjective evaluation for the physical condition during the day is low, the user U is short of sleep. This is thought to be one of the reasons for lowering the evaluation of activities. For this reason, the sleep improvement support apparatus 1 presents information for securing the user U's sleep time.

As another example, when the evaluation of the activity of the user U is low, even when the sleep efficiency is in an appropriate range, when the change in bedtime is large in a period shorter than the period used for calculating the sleep efficiency, It can be considered that the disturbance of the rhythm of the life of the user U is one of the factors that lower the evaluation of the activity. In this case, the sleep improvement support apparatus 1 presents information for adjusting the rhythm of life.

As described above, the sleep improvement support apparatus 1 according to the first embodiment is not limited to the sleep efficiency in the conventional CBT-i framework, but also the amount of time information variation in a period shorter than the period used for calculating the sleep efficiency. The quality of sleep of the user U is determined based on the above. Thereby, the sleep improvement assistance apparatus 1 can present the user U with more accurate information for supporting the improvement of sleep.

<Functional configuration of sleep improvement support apparatus 1>
FIG. 2 is a diagram schematically illustrating a functional configuration of the sleep improvement support apparatus 1 according to the first embodiment. The sleep improvement support apparatus 1 according to the first embodiment includes a storage unit 10 and a control unit 20.

The storage unit 10 includes a ROM (Read Only Memory) that stores a BIOS (Basic Input Input Output System) of a computer that implements the sleep improvement support device 1, a RAM (Random Access Memory) that is a work area of the sleep improvement support device 1, A mass storage device such as an SSD (Solid State Drive) or HDD (Hard Disk Drive) that stores an OS (Operating System), an application program, and various types of information referred to when the application program is executed.

The control unit 20 is a processor such as a CPU or a GPU (Graphics Processing Unit) of the sleep improvement support device 1, and executes a program stored in the storage unit 10 to execute a time information acquisition unit 21, an activity evaluation acquisition unit 22, It functions as an alarm management unit 23, a calculation unit 24, a presentation unit 25, and a productivity evaluation acquisition unit 26.

The time information acquisition unit 21 acquires time information related to the sleep of the user U, including the user U's bedtime, sleep time, wake-up time, and wake-up time. The time information acquisition unit 21 estimates and acquires time information by analyzing information acquired by using an acceleration sensor and a microphone (not shown) of the sleep improvement support device 1 using a known algorithm.

The activity evaluation acquisition unit 22 acquires an activity evaluation that is the user U's own evaluation regarding the condition of the user U during the activity.
FIGS. 3A and 3B are diagrams schematically illustrating an example of an activity evaluation input screen displayed on the display unit of the sleep improvement support apparatus 1 by the activity evaluation acquisition unit 22. Specifically, FIG. 3A shows an example of a screen before the user U inputs an activity evaluation, and FIG. 3B shows an example of a screen after the user U inputs an activity evaluation.

The activity evaluation acquisition unit 22 acquires activity evaluations in five stages from 1 to 5. As an example, activity evaluation shows that it is so bad that a numerical value is small. In the example shown in FIGS. 3A to 3B, the activity evaluation is represented by the number of stars. FIG.3 (b) has shown that activity evaluation is 3 (three stars) in five steps.

As shown in FIGS. 3A to 3B, the activity evaluation input screen also serves as an alarm setting screen used by the user U for awakening. The alarm management unit 23 manages alarms in the sleep improvement support apparatus 1. The user U cannot set an alarm when no activity evaluation is input. That is, the alarm management unit 23 permits the setting of an alarm used by the user U for awakening on condition that the activity evaluation acquisition unit 22 acquires the user U's own evaluation regarding the condition of the user U's activity. Thereby, the sleep improvement assistance apparatus 1 can raise the probability which acquires the activity evaluation of the user U used as the information useful for selection of the information for improving the user's U sleep.

Returning to the explanation of FIG. The calculation unit 24 calculates the sleep efficiency of the user U and the amount of change in the time information based on the time information acquired by the time information acquisition unit 21. The presentation unit 25 presents information for improving the sleep of the user U to the user U based on the sleep efficiency and fluctuation amount calculated by the calculation unit 24 and the activity evaluation acquired by the activity evaluation acquisition unit 22. Specifically, the presentation unit 25 displays information for improving the sleep of the user U on the display unit of the sleep improvement support device 1 or outputs the information from a speaker (not shown) included in the sleep improvement support device 1 by voice. By presenting it to the user U. Thereby, the user U can get an opportunity to touch information for improving his / her sleep.

There are various types of information that the presentation unit 25 presents to the user U, but the information for improving the sleep of the user U includes a bedtime that the user U should go to bed as representative. Although not shown, the sleep improvement support apparatus 1 according to the first embodiment causes the user U to input an ideal wake-up time desired by the user U as an initial setting. The presentation unit 25 acquires the bedtime that the user U should go to bed based at least on the ideal wake-up time desired by the user U.

FIG. 4 is a table showing rules for calculating an appropriate bedtime in a table format. As shown in FIG. 4, the appropriate bedtime of the user U is determined by an activity evaluation related to the ideal wake-up time of the user U, the sleep efficiency of the user U, and the condition during the activity of the user U. In FIG. 4, “good” activity evaluation indicates that the evaluation is 3 or more out of 5 levels. Also, “bad” activity evaluation means that the evaluation is 2 or less out of 5 levels.

If the activity evaluation of the user U is “good”, it is considered that at least the user U does not feel subjective sleepiness. Therefore, it is not necessary to change the user U's bedtime. For this reason, when the activity evaluation of the user U is “good”, the time obtained by subtracting the average bedtime of the previous week from the ideal bedtime is calculated as the appropriate bedtime of the user U.

Here, the “bedtime” is the total amount of time that the user U has been on the floor, and is specifically the difference between the bedtime and the wake-up time. Therefore, the bedtime is longer than the sleep time. Therefore, the time obtained by subtracting the average bedtime of the previous week from the ideal wake-up time is earlier than the time obtained by subtracting the average sleep time of the previous week from the ideal wake-up time. If the sleep efficiency of the user U is in an appropriate range, it is considered that the sleep efficiency is maintained by the user U going to bed at an appropriate bedtime.

On the other hand, when the user U is short of sleep, the sleep time of the user U will occupy most of the bedtime (95% or more), and as a result, it will be longer than the average sleep time of the previous week. If the sleep shortage of the user U is resolved, the sleep time of the user U is naturally shortened, and as a result, it can be expected that the sleep efficiency of the user U falls within an appropriate range.

When the activity evaluation of the user U is “bad” and the sleep efficiency of the user U is equal to or higher than a predetermined value, the time when the user U should go to bed is the ideal bedtime from the ideal awakening time to the average bedtime of the previous week. The time is calculated by subtracting 30 minutes. That is, the time at which the user U should go to bed is a time that is 30 minutes earlier than the average bedtime of the previous week. If the user U goes to bed at the presented bedtime, the sleep time of the user U will be longer. As a result, if the sleep shortage of the user U is resolved, it can be expected that the sleep efficiency of the user U is also within an appropriate range.

Here, the “predetermined value” is a “undersleep judgment criterion threshold” that the presentation unit 25 refers to in order to determine whether or not the probability that the user U is undersleep is high. A specific value of the sleep deprivation determination reference threshold may be determined in consideration of the lifestyle of the user U targeted by the sleep improvement support device 1. An example of the sleep shortage determination criterion threshold is a case where sleep efficiency is 95% or more, but the evaluation for subjective daytime condition is bad.

Thus, when the sleep efficiency of the user U is higher than a predetermined value, the presentation unit 25 sets the sleep time to be equal to or higher than the average sleep time of the previous week regardless of whether the activity evaluation of the user U is good or bad. Information including the action to be taken by the user U is presented.

On the other hand, when the sleep efficiency of the user U is in an appropriate range (that is, when the sleep efficiency is in the range of 85% or more and less than 95%), the reason why the activity evaluation of the user U is “bad” is a factor other than the bedtime. There is a high probability. In this case, the presentation unit 25 recommends that information other than the bedtime information, for example, recommend appropriate exercise or refrain from caffeine, recommended bathing time, recommended napping time zone, and smartphone before bedtime. And information such as avoiding blue light emitted by the PC is presented to the user U.

In addition, when the sleep efficiency of the user U is less than 85%, a general CBT-i program is considered effective. Since CBT-i is known and detailed description is omitted, when the sleep efficiency of the user U is less than 85%, the time when the user U should go to bed is the ideal wake-up time and the average sleep time of the previous week. It is determined based on. In any case, the presentation unit 25 causes the difference between the bedtime to be presented and the ideal wake-up time to be 5 hours or more.

As described above, information for improving sleep is also provided for the user U who is not targeted by the conventional CBT-i, such as the user U who is suspected of lack of sleep and the user U whose sleep efficiency is in an appropriate range. Thereby, the sleep improvement support apparatus 1 can provide information for improving sleep for more users U than the conventional CBT-i.

Returning to the explanation of FIG. The productivity evaluation acquisition unit 26 acquires the productivity evaluation that is the user U's own evaluation regarding the productivity of the user U. Here, “productivity evaluation” means self-evaluation indicating the performance related to the work of the user U, among the activities of the user U. The productivity evaluation acquisition unit 26 may acquire the productivity evaluation in five stages from 1 to 5 in the same manner as the activity evaluation, or the known WHO-HPQ (WHO Health and Work Performance Questionnaire; World Health Organization Health and Health A questionnaire on labor performance) may be used.

The presentation unit 25 changes information to be presented to the user U in order to improve the productivity of the user U based on the sleep efficiency of the user U. For example, when the sleep efficiency of the user U is out of the proper range, the presentation unit 25 presents information including actions that the user U should take in order to make the sleep efficiency of the user U fall within the proper range. The specific information presented by the presentation unit 25 is the same as the information described above regarding activity evaluation.

In addition, when the presentation unit 25 is in a range where the sleep efficiency of the user U is appropriate and the productivity evaluation of the user U is low, the presentation unit 25 may provide information other than bedtime information, for example, an appropriate break Information such as exercise recommendations is presented to the user U.

Next, an example of information indicating the amount of change in time information calculated by the calculation unit 24 will be described.
The calculation unit 24 according to the first embodiment calculates a “sleep score” based on the amount of change in time information. The sleep score is designed so that 100 is the highest score, and the score is reduced as the fluctuation amount of the time information increases.

FIG. 5 is a diagram showing a rule for calculating a sleep score in a table format. As shown in FIG. 1 to R.I. Includes 5 rules up to 5. In FIG. 1 and R.A. As shown in FIG. 2, the calculation unit 24 calculates the amount of change in time information in an interval (three days in the example shown in FIG. 5) that is shorter than the period used for calculating sleep efficiency in the CBT-i framework.

Specifically, R.D. 1, the calculation unit 24 calculates a difference D1 between the latest bedtime and the average bedtime in a period three days after the latest bedtime. The calculation unit 24 divides the calculated D1 by 6 and rounds off the decimal part, or 15, whichever is smaller, A deduction based on 1. In FIG. 5, symbol [] indicates a Gaussian symbol. That is, [x] represents the largest integer not exceeding x. The calculation unit 24 is an R.I. For point 2, the deduction is obtained by the same calculation.

Calculating unit 24 is R.D. 3, the difference D3 of the latest sleep time with respect to the average sleep time during one week is calculated. The calculation unit 24 divides the calculated D3 by 6 and rounds off the fractional part or 20 to the smaller of the R.R. A deduction based on 3.

Where R. 3 is R.I. 1 and R.A. An average sleep time of 1 week, which is longer than 2, is used. This one week is as long as the period used for sleep efficiency in the CBT-i framework. Since the latest sleep time is also referred to in 3, the value reflects the latest situation rather than sleep efficiency.

Calculating unit 24 is R.D. According to 4, the deduction point is referred to based on the percentage R of the latest bedtime with respect to the latest sleep time. R. No. 4 is designed so that the deduction point becomes larger as R becomes smaller. Similar to the calculation of sleep efficiency in the CBT-i framework in terms of the percentage of bedtime with respect to sleep time. No. 4 is a value reflecting the latest situation rather than sleep efficiency because the sleep time and bedtime use the latest values. In addition to this, the calculation unit 24 may perform R.D. According to 5, a deduction is calculated based on activity evaluation A.

As described above, the calculation unit 24 increases (1) the difference D1 between the latest bedtime and the average bedtime in the period that is a first number of days (for example, three days) back from the latest bedtime. (2) The larger the difference D2 between the latest wake-up time and the average wake-up time in the period retroactive to the first number of days from the latest wake-up time, the greater (3) the second number of days longer than the first number of days (for example, one week) As the difference D3 of the latest sleep time with respect to the average sleep time during () increases, or (4) the ratio R of the latest bedtime to the latest sleep time decreases, the sleep score that becomes a smaller value becomes time information. It is calculated as the amount of fluctuation. Thereby, the calculation unit 24 can calculate an index reflecting the latest situation rather than sleep efficiency in the framework of CBT-i.

FIG. 6 is a diagram schematically illustrating an example of a sleep score notification screen generated by the presentation unit 25, and a diagram illustrating an example of a report screen that the presentation unit 25 presents to the user U every week. By looking at the report screen at a glance, the user U can grasp a sleep score that directly represents the quality of sleep of the user U. Further, the user U can visually grasp the change in the bedtime and the change in the wake-up time. Although not shown in FIG. 6, the presentation unit 25 may further display “wake-up time” and “wake-up time” on the notification screen.

When the user U performs an operation such as sliding the report screen displayed on the display unit of the sleep improvement support apparatus 1, the report screen transitions to an advice notification screen (not shown). On the advice notification screen, information selected by the presentation unit 25 based on the sleep efficiency, the fluctuation amount, and the activity evaluation is displayed.

For example, when the user U goes to bed at a time later than the normal bedtime, the presenting unit 25 displays the advice notification screen on the next day. I'm busy. First, let's go to bed within an hour of ideal bedtime. " As another example, when the user U starts an activity at a time later than the wake-up time on weekdays on a holiday, the presentation unit 25 may indicate that “sleeping is comfortable, but actually it is also a cause of an upset holiday. The message “Let's get up on a weekday (within 2 hours at most) and get back a stable life” is displayed.

Thus, the presentation unit 25 specifically presents advice for improving the sleep of the user U based on the fluctuation of the daily time information of the user U. The presentation unit 25 refers to a database in which a plurality of patterns related to sleep efficiency, fluctuation amount, and activity evaluation are associated with messages to be presented, and acquires messages to be displayed on the advice notification screen. This database may be prepared in advance by a developer or the like of an application program for realizing sleep improvement support.

<Effects of sleep improvement support apparatus 1 according to the first embodiment>
As explained above, according to the sleep improvement support apparatus 1 which concerns on 1st Embodiment, improvement of the quality of sleep of the user U individual can be supported. In particular, the sleep improvement support device 1 uses the sleep quality of the user U based on the fluctuation amount of time information in a period shorter than the period used for calculating the sleep efficiency in addition to the sleep efficiency in the conventional CBT-i framework. Determine. Thereby, the sleep improvement assistance apparatus 1 can present the user U with more accurate information for supporting the improvement of sleep.

<Second Embodiment>
The sleep improvement support apparatus 1 according to the first embodiment is mainly intended to improve the sleep of the individual user U. On the other hand, the organization improvement support apparatus 3 according to the second embodiment is different in that the organization as a whole composed of a plurality of users U aims to improve the sleep of the members. Therefore, the user U of the organization improvement support apparatus 3 according to the second embodiment is assumed to be an organization manager, a labor manager, or the like.

<Outline of Second Embodiment>
FIG. 7 is a diagram for explaining the outline of the organization improvement support system S according to the second embodiment. In the organization improvement support system S according to the second embodiment, it is assumed that a plurality of members E constituting the organization possess the sleep improvement support device 1 according to the first embodiment, respectively. Yes. The organization improvement support system S is connected in such a manner that the sleep improvement support device 1 and the organization improvement support device 3 possessed by each member E can communicate via the network N. The network N is realized by the Internet, for example.
