Description

Sleeping state detection system, sleeping state detection device, and sleeping state detection program

The present invention relates to a sleeping state detection system, a sleeping state detection device, and a sleeping state detection program, and more particularly to a system that detects whether a holder of a mobile terminal such as a smartphone is sleeping.

In recent years, smartphones (smartphones) have become widespread among children, and an increasing number of children use smartphones late at night for internet surfing, games, communication apps, and so on. And by staying up late, the body clock shifts, leading to a night shift in life, making it impossible to wake up early in the morning, and as a result, the number of children who become late and fail to attend school is increasing. Also, if you operate your smartphone in the futon before going to bed, it may cause health problems such as sleep problems.

In view of these problems, schools and local governments have formulated unified rules, and movements to limit the use of smartphones at night by children are spreading throughout the country. For example, local governments that have established unified rules such as “parents keep their smartphones after 9pm” are known. This kind of regional unification rule has the merit of making it easier for parents to pay attention to their children.

However, the unified rule is an arbitrary initiative and is not necessarily implemented in each household. For example, although the use of a smartphone at night is prohibited as a domestic rule due to the circumstances of the family, there are cases where the parent cannot leave the smartphone. In that case, even if the child steals the parents' eyes and uses the smartphone until late at night in their own room, because the parents can not grasp such usage situation, there is a problem that it can not be careful there were.

A technique is known in which a sensor is provided on a bed or a human body and a sleep state is determined based on a detected body motion signal (see, for example, Patent Document 1). In Patent Document 1, an illuminance sensor that detects the illuminance in the room is provided in the sleep determination device, and when the detected illuminance of the illuminance sensor falls below the specified illuminance after the time of entering the floor determined based on the body motion signal, It is described that correction is performed with the time when the detected illuminance decreases as the time of entry.

Also known is a technique for determining whether or not a user is going to sleep based on ambient illuminance (see, for example, Patent Document 2). In this Patent Document 2, when the current time information becomes bedtime information and the detection device detects that the illumination device in the vicinity of the bed is turned on, even though the illumination device in the hospital room is turned off. It is described that it is determined that a patient is awake and a notification device is used for notification.

Furthermore, a technique is also known in which the user's wake-up is determined based on the state of the mobile communication device and the ambient illuminance (see, for example, Patent Document 3). In Patent Document 3, the wake-up condition that the acceleration generated in the mobile communication device is equal to or higher than the reference value and the ambient illuminance is higher than the reference value is satisfied, and unreported schedule information or unconfirmed incoming information is stored in the mobile communication device. It is described that an alarm sound is output when

JP 2007-202681 A JP 2009-284998 A Japanese Patent Application Laid-Open No. 2014-053801

In the techniques described in Patent Documents 1 and 2 above, it is possible to determine a person's sleep state, but it is not possible to determine whether or not the user is awake while using a smartphone. On the other hand, in the technique described in Patent Document 3, it is possible to check the state in which the user wakes up in the morning and uses the mobile communication device based on the acceleration of the mobile communication device and the ambient illuminance.

However, even if the technology described in Patent Document 3 is used, the child is turned off late at night and the smartphone is used in the futon, or the smartphone is placed on a desk or bed. It may not be possible to detect that you are using a smartphone. If this continues every day, parents cannot pay attention to their children, which may cause adverse effects such as sleep disturbance due to the night-type of life, regularization of late arrival, and school refusal.

The present invention has been made to solve such a problem, and enables a child to detect a state of using a smartphone until late at night and notify the parent as much as possible. With the goal.

In order to solve the above-described problem, in the present invention, based on the use state of the bedding, the ambient illuminance, and the use state of the mobile terminal, it is determined whether or not the owner of the mobile terminal is sleeping on the bedding, The determination result is notified to a third party other than the owner of the portable terminal.

According to the present invention configured as described above, the owner of the mobile terminal wakes up using the mobile terminal on the bedding from the three elements of the usage state of the bedding, the ambient illuminance, and the usage state of the mobile terminal. Since it is determined comprehensively whether the child who is the owner of the mobile device is using the mobile device on the bedding until late at night, Can be notified.

It is a figure which shows the example of whole structure of the sleeping state detection system by this embodiment. It is a block diagram which shows the function structural example of the sleeping state detection system by this embodiment. It is a flowchart which shows the operation example of the sleeping state detection system by this embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of the overall configuration of a sleeping state detection system according to the present embodiment. As shown in FIG. 1, the sleeping state detection system according to the present embodiment includes a child portable terminal 100 such as a smartphone held by a child who is a sleeping state detection target, and a bedding (e.g., bed) 600 used by the child. The apparatus includes a sensor device 200 to be installed, a wireless LAN access point 300, and a parent portable terminal 400 such as a smartphone held by a parent who is a notification target of a sleeping state.

The sensor device 200 includes various sensors described later, a wireless communication function using Bluetooth (registered trademark, the same applies hereinafter), and a wireless communication function using a wireless LAN. The child portable terminal 100 and the sensor device 200 are wirelessly connected by Bluetooth. Further, the sensor device 200 and the parent portable terminal 400 are wirelessly connected via a wireless LAN via the access point 300.

FIG. 2 is a block diagram illustrating a functional configuration example of the sleeping state detection system according to the present embodiment. As shown in FIG. 2, the child portable terminal 100 includes a portable terminal use state detecting unit 11 as a functional configuration. Moreover, the sensor apparatus 200 is provided with the bedding use state detection part 21, the illumination intensity detection part 22, the bedtime determination part 23, the alerting | reporting part 24, and the notification part 25 as the function structure.

The mobile terminal use state detection unit 11 included in the child mobile terminal 100 is configured by application software installed in the child mobile terminal 100, for example. That is, the child portable terminal 100 is configured to include a microcomputer having a CPU, a RAM, a ROM, and the like, and the function of the portable terminal use state detecting unit 11 is a program stored in a recording medium such as a hard disk or a semiconductor memory. Is realized by processing.

The functional blocks 21 to 25 included in the sensor device 200 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, each of the functional blocks 21 to 25 is actually configured by including a microcomputer having a CPU, a RAM, a ROM, and the like, and is stored in a recording medium such as a RAM, a ROM, a hard disk, or a semiconductor memory. This is realized by the program running.

The mobile terminal usage state detection unit 11 detects the usage state of the child mobile terminal 100. For example, the mobile terminal usage state detection unit 11 sequentially detects the CPU usage rate of the child mobile terminal 100 as mobile terminal usage state information. Then, the detected CPU usage rate information is sequentially supplied to the sleep determination unit 23 of the sensor device 200 via Bluetooth.

When the child uses the child portable terminal 100, the CPU usage rate varies depending on the usage state. On the other hand, when the child does not use the child portable terminal 100, the CPU usage rate is stable at a substantially constant value. Therefore, it can be said that the value of the CPU usage rate is information indicating the usage state of the child portable terminal 100.

Note that although the CPU usage rate is detected here, the present invention is not limited to this. For example, the mobile terminal usage state detection unit 11 may detect the memory usage rate of the child mobile terminal 100. Or you may make it the portable terminal use condition detection part 11 detect the traffic amount of communication. In addition, any information whose value changes depending on whether or not the child mobile terminal 100 is used can be applied as a detection target of the mobile terminal use state detection unit 11.

The bedding usage state detection unit 21 detects the usage state of the bed 600 by a child. The bedding use state detection unit 21 includes, for example, a vibration sensor, and detects vibration of the bed 600 in which the sensor device 200 is installed as bedding use state information. Then, the bedding use state detection unit 21 sequentially supplies the vibration information detected by the vibration sensor to the sleep determination unit 23.

Here, when the child is using the child portable terminal 100 while sleeping on the bed 600, the movement of the body at that time is transmitted to the bed 600, and the bed 600 vibrates, and the vibration is detected by the vibration sensor. On the other hand, when the child is not using the bed 600, the output value of the vibration sensor is zero. Therefore, it can be said that the vibration information detected by the vibration sensor is information indicating the use state of the bed 600.

Note that even when the child is sleeping in the bed 600, the output value of the vibration sensor is zero. When the vibration information indicates a sero value, the sleep determination unit 23 described later does not determine that the child is awake in the bed 600. Therefore, even when the bed 600 is used, there is no particular problem in that the vibration information (bedding use state information) indicates a sero value when sleeping.

Here, the vibration sensor is used to detect the use state of the bed 600, but the present invention is not limited to this. For example, the bedding use state detection unit 21 may include a pressure sensor, and pressure information detected by the pressure sensor may be supplied to the sleep determination unit 23 as bedding use state information representing the use state of the bed 600. In addition, any information whose value changes depending on whether or not the bed 600 is used can be applied as a detection target of the bedding use state detection unit 21.

The illuminance detection unit 22 includes an illuminance sensor, for example, and detects the illuminance around the bed 600 where the sensor device 200 is installed. The illuminance detected by the illuminance sensor varies depending on the lighting state of the child room where the bed 600 is placed. Alternatively, when the child uses the child portable terminal 100 near the sensor device 200, the illuminance detected by the illuminance sensor may vary depending on the display state of the display of the child portable terminal 100. The illuminance detection unit 22 sequentially supplies the detected illuminance information to the sleep determination unit 23.

The sleeping determination unit 23 is detected by the mobile terminal usage state information (for example, CPU usage rate information) indicating the usage state of the child mobile terminal 100 detected by the mobile terminal usage state detection unit 11, and the bedding usage state detection unit 21. Based on bedding use state information (for example, vibration information) indicating the use state of the bed 600 and the illuminance information indicating the illuminance around the bed 600 detected by the illuminance detection unit 22. It is determined whether or not a child is sleeping on the bed 600.

Specifically, the sleep determination unit 23 includes an information acquisition unit 23a and an information analysis unit 23b. The information acquisition unit 23a includes mobile terminal usage state information (CPU usage rate information) that indicates the usage state of the child mobile terminal 100, bedding usage state information (vibration information) that indicates the usage state of the bed 600, and illuminance that represents ambient illuminance. Three pieces of information are taken as one information set, and the information set is repeatedly acquired at a predetermined time interval (for example, every 30 seconds).

The information analysis unit 23b receives the mobile terminal use state information, the bedding use state information, and the illuminance information acquired by the information acquisition unit 23a from each of the mobile terminal use state detection unit 11, the bedding use state detection unit 21, and the illuminance detection unit 22. A three-dimensional principal component analysis with three axes is performed, and it is determined whether or not the child who is the owner of the child portable terminal 100 is sleeping on the bed 600 based on at least the information of the first principal component.

For example, the information analysis unit 23b plots each value acquired every 30 seconds on a three-dimensional coordinate having the mobile terminal use state information as the X axis, the bedding use state information as the Y axis, and the illuminance information as the Z axis. . Then, an axis is taken in the direction in which the variance of values becomes the largest, and this is taken as the first main component. Further, the remaining two axes are taken in two directions orthogonal to the axis, and the second main component and the third main component are set in descending order of dispersion.

Here, the first to third principal components are n × 3 determinants using the mobile terminal usage state information, the bedding usage state information, and the illuminance information as variables and the principal component load amount as a weighting coefficient ( n can be obtained from the number of information sets acquired every 30 seconds. At this time, the weighting coefficient assigned to each element of the matrix is obtained by calculating eigenvalues corresponding to the principal components of the matrix. The eigenvalue corresponds to the variance of the principal component and is a value representing how much the principal component holds the original information. By using the eigenvalue of the matrix as a weighting coefficient, the first principal component is determined because the variance is maximized, and the second principal component and the third principal component are determined in a form orthogonal thereto.

The information analysis unit 23b determines whether or not the child is sleeping by determining the values of the first principal component to the third principal component and then comparing these values with a predetermined threshold value. For example, the information analysis unit 23b determines the sleeping state of the child depending on whether or not the value of the first principal component is greater than the first threshold value. Specifically, when the value of the first principal component is larger than the first threshold, it is determined that the child is waking up. The first threshold value used in this case may be a fixed value obtained empirically or experimentally, or may be a variable value that varies by machine learning.

When the first threshold is variably set by machine learning, for example, the following processing can be performed. That is, the value of the first principal component is accumulated over a plurality of days, and the distribution is set to a value that is bisected by a clustering method such as the k-means method. Alternatively, based on other information that can monitor the sleep / wake state such as an actigraph, the value of the first principal component that can most reflect the state is found by machine learning and set as a threshold value.

In addition, although the example which determines the sleeping state of a child by comparing with a 1st main component and a 1st threshold value was demonstrated here, this invention is not limited to this. For example, in addition to the comparison between the first principal component and the first threshold, at least one of the comparison between the second principal component and the second threshold and the comparison between the third principal component and the third threshold is performed, You may make it determine a sleeping state of a child based on those comparison results. For example, when all the principal component values are larger than the threshold, it is determined that the child is awake.

The alerting | reporting part 24 alert | reports the determination result by the bedtime determination part 23 to the parent portable terminal 400 via the access point 300. FIG. The timing for performing the notification can be arbitrarily designed. For example, when the sleep determination unit 23 determines that the parent is awake on the bed 600 later than the time set in advance for the sensor device 200 by the parent, the notification unit 24 displays the determination result for the parent mobile phone. Notify the terminal 400.

Specifically, the sleep determination unit 23 is always operated, and when it is determined that a child is waking up after a preset time, the notification unit 24 notifies the parent portable terminal 400 of that fact. Whether the time is after a preset time can be determined by a clock provided in the sensor device 200. Alternatively, the bedtime determination unit 23 may be activated when the preset time is reached, and notification may be performed when it is determined that the child is awake.

The parent who has received this notification can take an appropriate action such as cautioning the child to stop using the mobile terminal 100 for children.

When the bedtime determination unit 23 determines that the child has been woken up after a preset time, the notification unit 25 sets the preset time (the first set time) on the next day or a predetermined time thereafter. At an early time (second set time), a notification that prompts the user to refrain from using the child portable terminal 100 is sent to the child portable terminal 100.

For example, when the sleep determination unit 23 first determines that the child is awake until later than the first set time, the sleep determination unit 23 sets a notification flag in the notification unit 25. The notification unit 25 determines whether or not the notification flag is set when the second set time is reached, and when it is set, the notification unit 25 notifies the user to refrain from using the child portable terminal 100. This is performed for the child portable terminal 100.

As a result, after the day after the day when the notification flag is set by the bedtime determination unit 23, a notification prompting the user to refrain from using the child mobile terminal 100 is sent by the notification unit 25 at the second set time. 100 will be sent. Even if children who have received this notification have forgotten their time and are immersed in the use of the mobile device 100 for children, they can use the notification to stop using it and actually stop using it. Can do.

Note that the notification to the child portable terminal 100 by the notification unit 25 is made when the bedtime determination unit 23 determines that the child is waking up at the second set time, that is, the child is in bed at the second set time. It may be performed only when it is detected that the mobile terminal 100 for children is being used while in 600.

The above-described notification unit 24 does not notify the parent portable terminal 400 on the day when the sleeping determination unit 23 first determines that the child is awake until later than the first set time, Even when the notification unit 25 notifies the child mobile terminal 100 at the set time 2, the bedtime determination unit 23 determines that the child is awake until the first set time thereafter. In addition, the notification unit 24 may notify the parent portable terminal 400 to that effect.

In this way, the parent does not intervene in the child from the beginning, but first the child's mobile terminal 100 is advised to stop using the child mobile terminal 100 from the sleeping state detection system to the child, and still until late at night. Parents can intervene in their children if they do not stop using it.

FIG. 3 is a flowchart showing an operation example of the sleeping state detection system according to the present embodiment configured as described above. Note that the flowchart shown in FIG. 3 is repeatedly executed while the power of the sensor device 200 is turned on.

First, the bedtime determination unit 23 determines whether or not the second set time has come by referring to a clock provided in the sensor device 200 (step S1). If it is not the second set time, the determination process in step S1 is repeated. On the other hand, when the second set time is reached, the sleep determination unit 23 determines whether or not a notification flag is set in the notification unit 25 (step S2). If the notification flag is not set in the notification unit 25, the process proceeds to step S7.

On the other hand, when the notification flag is set in the notification unit 25, the information acquisition unit 23 a of the sleep determination unit 23 receives the mobile terminal from each of the mobile terminal use state detection unit 11, the bedding use state detection unit 21, and the illuminance detection unit 22. N sets of usage state information, bedding usage state information, and illuminance information are acquired at 30-second intervals (step S3). Then, the information analysis unit 23b performs a three-dimensional principal component analysis using the acquired information (Step S4), and determines whether or not the child is awake on the bed 600 (Step S5).

Here, when it is determined that the child does not get up on the bed 600, the process of the flowchart shown in FIG. 3 ends. On the other hand, when the sleep determination unit 23 determines that the child is awake on the bed 600, the notification unit 25 notifies the child mobile terminal 100 of a notification to refrain from using the child mobile terminal 100. It performs (step S6). Thereafter, the bedtime determination unit 23 determines whether or not the first set time has come (step S7). If it is not the first set time, the determination process in step S7 is repeated.

On the other hand, when the first set time is reached, the information acquisition unit 23a of the sleeping determination unit 23 receives the mobile terminal usage state information from the mobile terminal usage state detection unit 11, the bedding usage state detection unit 21, and the illuminance detection unit 22, respectively. Then, n sets of bedding usage state information and illuminance information are acquired at 30-second intervals (step S8). Then, the information analysis unit 23b performs a three-dimensional principal component analysis using the acquired information (step S9), and determines whether or not the child is awake on the bed 600 (step S10).

Here, when it is determined that the child does not get up on the bed 600, the process of the flowchart shown in FIG. 3 ends. On the other hand, when it is determined that the child is awake on the bed 600, the sleep determination unit 23 determines whether a notification flag has been set in the notification unit 25 (step S11). When the notification flag has been set, the child mobile terminal 100 is used even at the first set time after the notification to the child mobile terminal 100 at the second set time in step S6. Means not stopping. In this case, the alerting | reporting part 24 alert | reports to the parent portable terminal 400 that the determination result by the sleep determination part 23, ie, the child is waking up using the child portable terminal 100 in the bed 600 (step S12). Thereby, the process of the flowchart shown in FIG. 3 is completed.

On the other hand, when the notification flag has been set, the sleep determination unit 23 sets the notification flag in the notification unit 25 (step S13). Thereby, the process of the flowchart shown in FIG. 3 is completed. In this case, the notification to the parent portable terminal 400 is not performed on this day, but if the child is using the child portable terminal 100 until late at night, the notification to the parent portable terminal 400 is performed in step S12. Is called.

As described above in detail, in the present embodiment, the child who is the owner of the child mobile terminal 100 is based on the use state of the child mobile terminal 100, the use state of the bed 600, and the illuminance around the bed 600. It is determined whether or not the user is sleeping on 600 and the determination result is notified to the parent portable terminal 400.

According to the present embodiment configured as described above, the child uses the child portable terminal 100 on the bed 600 from the three elements of the use state of the child portable terminal 100, the use state of the bed 600, and the ambient illuminance. Since it is determined comprehensively whether or not it is happening in the state, it is possible to detect the state that the child is using the child portable terminal 100 on the bed 600 until late at night as much as possible and notify the parent. it can. The parent who has received this notification can intervene such as paying attention to the child at an appropriate timing.

In addition, although the sensor apparatus 200 demonstrated the structural example provided with a vibration sensor and an illumination intensity sensor in the said embodiment, this invention is not limited to this. For example, a vibration sensor and an illuminance sensor may be provided separately from the sensor device 200, and the bedding usage state detection unit 21 and the illuminance detection unit 22 may input the vibration information and the illuminance information detected by these sensors.

When the illuminance sensor is provided separately from the sensor device 200, an illuminance sensor may be attached to the child portable terminal 100 to detect the illuminance around the child portable terminal 100. By doing this, it is possible to obtain illuminance information by detecting the illuminance by the light emitted from the display of the child portable terminal 100 even if the room is turned off.

Moreover, although the said embodiment demonstrated the structure with which both the alerting | reporting part 24 and the notification part 25 are provided in the sensor apparatus 200, this invention is not limited to this. For example, the notification unit 25 may be omitted and only the notification unit 24 may be provided. In this case, the parent portable terminal 400 may include the functions of the sleep determination unit 23 and the notification unit 24 instead of the sensor device 200.

That is, the mobile terminal usage state detection unit 11, the bedding usage state detection unit 21, and the illuminance detection unit 22 sequentially transmit the mobile terminal usage state information, the bedding usage state information, and the illuminance information from the sensor device 200 to the parent mobile terminal 400. To do. Then, the sleeping determination unit 23 provided in the parent portable terminal 400 acquires these pieces of information and performs principal component analysis so that the parent portable terminal 400 determines whether or not the child is sleeping. Good.

Moreover, in the said embodiment, although the flowchart of FIG. 3 was shown as an operation example of a sleeping state detection system, this invention is not limited to this. That is, in the example of FIG. 3, the operations of the bedtime determination unit 23, the notification unit 24, and the notification unit 25 are executed only after the second set time. On the other hand, the operation of the bedtime determination unit 23 is always performed, and when it is determined that the child is waking up, it is determined whether or not it is the second set time and after the first set time. The operations of the notification unit 25 and the notification unit 24 may be executed according to the determination result.

In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
