Here, the intensity of light may represent the luminance of light emitted from the light source or the luminance of light emitted from the light source reflecting the distance to the user. The irradiation time of light may indicate the duration of light irradiated to the user for light therapy.

The electronic device 101 uses information about the user's wake-up time received from the sensor of the electronic device 101 or the external electronic device 101 so that the user's wake-up time can be moved to the target wake-up time by a preset target date. A light treatment schedule may be created using the light treatment schedule. Hereinafter, the use of the user's wake-up time for moving the user's sleeping time will be mainly described, but the present invention is not limited thereto, and the user's rising time and the central time of the user's wake-up time may be used in addition to the user's wake-up time. For example, when the central time between the elevation time and the center time is advanced by 30 minutes, it may be determined that the user's sleep time is moved by 30 minutes.

The external electronic device 110 may include various sensors that sense the user's biometric information used to determine the user's wake-up time. The external electronic device 110 is a wearable electronic device configured in a form wearable by a user (eg, a watch, an eye patch, a ring, a bracelet, an anklet, a necklace, clothing, a bio implantable device, a hair band, etc.), a location where the user sleeps It may be an electronic device configured to be fixed to (a bed, a pillow, etc.).

According to the generated light source control command, the electronic device 101 or the light irradiation device 120 may control the light source to emit light corresponding to the light intensity or light irradiation time included in the phototherapy schedule to the user. there is. For example, the electronic device 101 or the light irradiation device 120 may control the intensity of light emitted from the light source, the wavelength of light, and the irradiation time of light to correspond to the intensity of light or the irradiation time of light. A detailed method of controlling the light source by the electronic device 101 or the light irradiation device 120 will be described later.

As described above, the user can perform light therapy according to the light therapy schedule generated by the electronic device 101 without the need to directly create a light therapy schedule for moving the sleep time, and to perform the light therapy, the electronic Since not only the light source of the device 101 but also all electronic devices including the light source can be used, light therapy can be performed more conveniently and efficiently.

2 is a flowchart of a method of controlling a light source to move a user's sleeping time according to various embodiments of the present disclosure.

In step 211, the electronic device 101 may create a light therapy schedule so that the user's wake-up time can be adjusted to the target wake-up time by a preset target date. The light therapy schedule may be generated using information about a target date, a target wake-up time, and a wake-up time, and may include information about at least one of the intensity of light emitted to the user and the irradiation time of light emitted to the user. In addition, the light therapy schedule may further include information about a time at which light therapy is performed, eg, a time at which light is irradiated to the user for light therapy. The user's wake-up time may be obtained through a sensor included in the electronic device 101 or, although not shown, may be obtained according to information about the user's wake-up time received from the external electronic device 110 .

The electronic device 101 may generate a light treatment schedule based on the history of generating a light treatment schedule in the past for the user. Meanwhile, when there is no previous history of creating a light treatment schedule for the user, the electronic device 101 schedules the light treatment schedule based on information about the relationship between the amount of light stored in the memory of the electronic device 101 and the movement amount at wake-up time. can create The information on the relationship between the amount of light and the adjustment amount of the wake-up time is information on the movement amount of the wake-up time adjusted when light is irradiated with a specific amount of light, and may include information about the movement amount of the wake-up time adjusted according to various amounts of light. .

Information on the relationship between the initial amount of light and the amount of movement at the time of waking up may be generated based on statistics or experiments on the relationship between the amount of general light and the amount of movement at the time of waking up of the user and stored in the memory. Here, the amount of light may represent the total amount of light emitted from the light source. In this way, since the amount of light can be expressed based on the intensity of light and the irradiation time of light, the intensity of light and the irradiation time of light can be determined so that a specific amount of light is irradiated. Information on the relationship between the amount of light and the movement amount at wake-up time may be updated by the electronic device 101 to match the characteristics of the user.

In step 212 , the electronic device 101 may generate a control signal including a command for controlling the light source according to the generated light treatment schedule and transmit the generated control signal to the light irradiation device 120 . Also, although not shown, the electronic device 101 may control a light source included in the electronic device 101 according to a command for controlling the light source. The control signal may include information on at least one of an intensity of light irradiated to the user and an irradiation time of light.

The electronic device 101 may transmit the control signal to the light irradiation device 120 when the time for performing the light treatment arrives according to the light treatment schedule. For example, when the user's wake-up time is advanced, a control signal for blocking the light is transmitted to the light irradiation device 120 before the user rises up based on the user's wake-up time, and the light is emitted after the user wakes up. A control signal for irradiating may be transmitted to the light irradiation device 120 . In the case of delaying the user's wake-up time, a control signal for irradiating light is transmitted to the light irradiation device 120 before the user rises up, and a control signal for blocking light after the user wakes up is transmitted to the light irradiation device ( 120) can be transmitted. Accordingly, the time at which the electronic device 101 transmits a control signal for controlling the light source to the light irradiation device 120 may be different each time light therapy is performed.

In step 213, the light irradiation device 120 may control a light source included in the light irradiation device 120 according to a command included in the received control signal. For example, the light irradiation device 120 may control at least one of an intensity of light emitted through a light source or an irradiation time of light.

In step 214, the external electronic device 110 may detect information for determining the user's wake-up time, such as the user's biometric information or the user's movement information, through various sensors. In step 215, the external electronic device 110 determines whether the user wakes up from the sleep state according to the sensed information, and when the user wakes up from the sleep state, determines the wake-up time of the user. In step 216, the external electronic device 110 may transmit information about the determined user's wake-up time to the electronic device 101.

In step 217 , the electronic device 101 may correct the light treatment schedule according to information about the user's wake-up time received from the external electronic device 110 . The electronic device 101 may correct the light treatment schedule to suit the characteristics of the user according to the received information about the user's wake-up time. Also, although not shown, the electronic device 101 may directly obtain information about the user's wake-up time through a sensor of the electronic device 101 and correct the phototherapy schedule using the obtained information. In addition, the electronic device 101 may also update information about the relationship between the amount of light and the movement amount of the wake-up time to match the characteristics of the user in the step of correcting the light therapy schedule.

In operation 218 , the electronic device 101 may generate a control signal including a command for controlling the light source according to the corrected light treatment schedule and transmit the generated control signal to the light irradiation device 120 . In step 219 , the light irradiation device 120 may control a light source included in the light irradiation device 120 according to a command included in the received control signal.

3 is a flowchart of a method of generating a light treatment schedule for moving a sleep time by an electronic device according to various embodiments of the present disclosure.

In step 310, the electronic device 101 may acquire the user's wake-up time. The wake-up time of the user is a time point when the user wakes up from a sleep state, and may be obtained according to a sensor included in the electronic device 101, a sensor included in the external electronic device 110, or a user's input.

For example, a user may input his or her wake-up time into the electronic device 101 through an input/output interface. Also, the user's wake-up time may be obtained according to the user's biometric information or the user's motion information sensed through a sensor included in the electronic device 101 . In addition, the external electronic device 110 determines the user's wake-up time according to the user's biometric information or the user's movement information sensed through the sensor of the external electronic device 110, and transmits information about the determined wake-up time to the electronic device. It can be sent to (101). The electronic device 101 may obtain the user's wake-up time through the received information on the wake-up time. The wake-up time of the user may be used to create a light treatment schedule or determine whether to move the user's sleeping time.

The user's movement information used to determine the user's wake-up time may be obtained through an acceleration sensor, a gyro sensor, or the like included in the external electronic device 110 . In addition, the user's biometric information and a sensor for sensing the biometric information used to determine whether the user wakes up from a sleep state are shown in Table 1.

However, this is only for the purpose of explanation, and is not limited thereto, and information about the user, such as various biometric information that can be sensed and the degree of movement, can be used to determine whether the user wakes up from sleep.

biometric information sensor Biometric information content heart rate Electrocardiogram (ECG) sensor Heart rate, variance of heart rate variability Breath pressure sensor respiratory rate, respiratory rate EEG Electroencephalogram (EEG) sensor α wave, θ wave content sweating, body temperature temperature and humidity sensor Changes in sweating and core body temperature eye movement Safety level (EOG) sensor Content of low-frequency components blink camera Camera opening degree, number of eye blinks, closing eye time

In addition, the external electronic device 110 includes a piezoelectric sensor and may be placed in a position where a user sleeps, such as a bed or a pillow. The external electronic device 110 may determine whether the user lies down to sleep or wakes up from the sleep state through a piezoelectric sensor.

In addition, the external electronic device 110 may determine whether the user wakes up from sleep according to an input such as a user who has woken up from sleep touching the external electronic device 110 .

In this way, the external electronic device 110 may determine whether the user wakes up from the sleep state, and may transmit information about the user's wake-up time according to the determination result to the electronic device 101 .

In step 320, the electronic device 101 determines the movement amount of the wake-up time per number of light irradiations to move the user's wake-up time to the target wake-up time based on the date the user's wake-up time was obtained, a preset target date, and the target wake-up time. can determine The electronic device 101 may determine the number of times light is irradiated according to the date of obtaining the wake-up time and the target date. The electronic device 101 may determine a wake-up time movement amount per number of light irradiation times in order to move the user's wake-up time to a target wake-up time according to the determined number of light irradiation times. The wake-up time movement amount per number of light irradiation times may be determined identically or differently for each number of light irradiation times.

In an embodiment, the electronic device 101 uses a user input received through an input/output interface of the electronic device 101, user schedule information stored in a memory of the electronic device 101, or a communication interface of the electronic device 101. A target date and a target wake-up time may be set based on at least one of the user's schedule information received from the external electronic device through the external electronic device. Here, the target wake-up time may indicate the final wake-up time to which the user's wake-up time will be moved through light therapy, and the target date may indicate a date to which the user's wake-up time will be moved to the target wake-up time.

The target date and target wake-up time may be manually set according to a user's input, or may be automatically set according to schedule information stored in the electronic device 101 or received from an external electronic device. Here, the schedule information may include all schedule information related to the user's schedule, such as schedule information managed through a schedule management application and schedule information managed through a travel application.

For example, the electronic device 101 compares the user's flight date and the time zone of the place where the user travels with the time zone of the current location by referring to the user's plane ticket purchase details or the travel itinerary input by the user to obtain the time difference can do. Accordingly, the electronic device 101 may automatically set a target date and a target wake-up time based on the acquired time difference and travel departure date. In addition, the electronic device 101 obtains information representing the shift work schedule input by the user, determines the shift date of the shift and the amount of movement of the user's sleep time according to the shift change through the information, and determines the target date and time according to the determination result. You can also automatically set a target wake-up time. As such, the information used to set the target date and the target wake-up time may be directly input by the user, obtained through information stored in the electronic device 101, or obtained through an external electronic device.

In step 330, the electronic device 101 may determine at least one of the intensity of the light irradiated to the user and the irradiation time of the light in order to move the user's wake-up time by the movement amount of the wake-up time per the determined number of light irradiation times.

Each person has a difference in circadian rhythm, which is a constant cycle in which sleep and wakefulness are repeated, and sensitivity to light may be different. Therefore, even when light is irradiated with light of the same intensity and with the same light cycle time, the movement amount of the wake-up time may vary from person to person. Accordingly, when the user has a history of performing phototherapy using the electronic device 101, the electronic device 101 determines the intensity of light irradiated to the user according to the history of performing phototherapy to suit the characteristics of the user. Alternatively, at least one of light irradiation time may be determined.

Meanwhile, when the user has no history of performing light therapy using the electronic device 101, the electronic device 101 uses the electronic device 101 according to information about the relationship between the amount of light stored in the memory of the electronic device 101 and the movement amount at the time of waking up. At least one of light intensity and light irradiation time may be determined. The information on the relationship between the amount of light and the movement amount at the time of waking up may be generated based on statistics or experiments on the relationship between the general amount of light and the amount of movement at the time of waking up of the user and stored in the memory of the electronic device 101 . In the step of determining at least one of light intensity and light irradiation time for the first time, the electronic device 101 uses information about the relationship between the amount of light stored in the memory and the moving amount at wake-up time. Information on the relationship between the amount of light and the movement amount at wake-up time can be updated according to . The electronic device 101 may correct the phototherapy schedule to suit the characteristics of the user by correcting at least one of light intensity or light irradiation time determined according to the information on the relationship between the updated amount of light and the amount of movement at wake-up time.

4 is a flowchart of a method of determining a wake-up time adjustment amount per number of irradiation times of light by an electronic device according to various embodiments of the present disclosure.

In step 410, the electronic device 101 may determine the number of irradiation times of light to be irradiated to the user in order to move the user's wake-up time to the target wake-up time by the target date. For example, when light is set to be irradiated once a day in order to move the user's wake-up time, the number of times the light is irradiated may be determined as a difference between a date when the user's wake-up time is acquired and a target date.

For example, when the target date is November 27th and the date on which the first wake-up time is obtained is November 23rd, the number of irradiation times of light may be determined to be four. Also, when the light is set to be irradiated twice a day to adjust the user's wake-up time, the number of times the light is irradiated may be determined by multiplying the difference between the first wake-up time and the target date by 2. For example, when the target date is November 27 and the date on which the first wake-up time is obtained is November 23, the number of times light is irradiated may be determined as 8 times.

In this way, the electronic device 101 may determine the number of times of irradiation of light to be irradiated to the user according to the difference between the date of obtaining the user's wake-up time and the target date and the number of times of light to be irradiated per day. The number of times of light to be irradiated per day may be set according to a user's characteristics according to a history of performing light therapy, or may be set according to a user's input.

In step 420, the electronic device 101 may calculate a difference between the user's wake-up time and the target wake-up time. The electronic device 101 may calculate a difference between the user's wake-up time and the target wake-up time in order to determine the amount of wake-up time to be moved from the date the user's wake-up time was acquired to the target date.

In step 430, the electronic device 101 may determine the amount of wake-up movement per number of times of light irradiation according to the difference between the user's wake-up time calculated in step 420 and the target wake-up time and the number of times of light irradiation determined in step 410. For example, when the number of light irradiation times is 4 and the difference between the user's wake-up time and the target wake-up time is 2 hours, the electronic device 101 may determine the movement amount of the wake-up time per number of light irradiations as 30 minutes. The wake-up time movement amount per number of times of light irradiation may be set equally for each number of times of light irradiation, or may be set differently for each number of times of light irradiation. For example, the shift amount of the wake-up time through the first irradiated light is determined to be 40 minutes, the shift amount of the wake-up time through the second irradiated light is determined to be 20 minutes, and the shift amount of the wake-up time through the third irradiated light is 50 minutes. It is determined as minutes, and the movement amount of wake-up time through the fourth irradiated light may be determined as 10 minutes.

5 is a flowchart of a method of determining at least one of an intensity of light or an irradiation time of light irradiated to a user by an electronic device according to various embodiments of the present disclosure.

The electronic device 101 may correct at least one of the intensity of light or the irradiation time of light determined according to the user's wake-up time obtained in the course of light therapy. Hereinafter, a method of correcting at least one of light intensity and light irradiation time determined according to the user's wake-up time obtained in the course of light therapy will be described.

In step 510, the electronic device 101 determines the user's wake-up time (hereinafter referred to as the first wake-up time) and the user's wake-up time stored in the memory of the electronic device 101. It is referred to as the second wake-up time.) can be calculated. The electronic device 101 may check the movement amount of the user's wake-up time moved according to the light irradiated to the user by calculating the difference between the first wake-up time and the second wake-up time.

In step 520, the electronic device 101 may update information about the relationship between the amount of light stored in the memory of the electronic device 101 and the shift amount of the time to wake up according to the calculated difference between the calculated first time to wake up and the second time to wake up. . As described above, the information on the relationship between the amount of light initially stored in the memory and the amount of movement at the time of waking up may be generated based on statistics or experiments on the relationship between the amount of general light and the amount of movement at the time of waking up of the user. Accordingly, the electronic device 101 may update information about the relationship between the amount of light and the movement amount at wake-up time to match the characteristics of the user. In addition, even if the information on the relationship between the amount of light and the movement amount at wake-up time has already been updated to match the user's characteristics, the electronic device 101 determines the relationship between the amount of light and the movement amount at wake-up time so as to more accurately reflect the user's characteristics. information can be updated.

In step 530, the electronic device 101 may determine at least one of the intensity of light irradiated to the user or the irradiation time of light according to the information about the relationship between the amount of light updated in step 520 and the movement amount at wake-up time. As such, the electronic device 101 can perform light therapy suitable for the user's characteristics.

6A and 6B are conceptual views illustrating a light treatment schedule generated by an electronic device according to various embodiments of the present disclosure.

According to various embodiments of the present disclosure, the electronic device 101 may generate a light therapy schedule such that the user's current wake-up time is adjusted to the target wake-up time by a preset target date. The light treatment schedule generated by the electronic device 101 can be conceptually represented as shown in FIGS. 6A and 6B.

Hereinafter, light therapy is performed three times from the first day of light therapy (DAY 1) to the target date (DAY 4), the target wake-up time is set to 11 o'clock according to the target sleep time 604, and the user's first day It is assumed that the expected sleep time 601 of (DAY 1) is from 9:00 to 17:00, and the expected sleep time 601 of the first day (DAY 1) may be set based on the obtained wake-up time of the user. In addition, light therapy is performed once a day, and the information about the relationship between the amount of light stored in advance and the amount of movement at wake-up time is when the light is irradiated with the first light amount, which is the amount of light when the light is irradiated for 1 hour with the intensity of the first light. It is assumed that the wake-up time is set to move 2 hours. In addition, it is assumed that the moving amount of the wake-up time per number of times of light irradiation is the same. Accordingly, the number of light irradiation times may be determined to be three, and the wake-up time movement amount per light irradiation number may be determined to be two hours.

In one embodiment, in order to advance the sleep time, it is effective to irradiate the user with light within a preset time after the user wakes up and block the light within a preset time before the user goes to bed. Hereinafter, for convenience of explanation, a time period in which light is irradiated according to at least one of light intensity or light irradiation time included in a light treatment schedule generated to advance or delay a user's sleep time is referred to as a light irradiation period, and a light irradiation period. The time interval blocking the light is referred to as a light blocking interval. However, in the light blocking section, the light irradiated to the user may be completely blocked, or in an environment where it is difficult to completely block the light irradiated to the user, the light may be irradiated with a light amount less than a preset threshold value. The threshold in the light blocking section may be set based on experiments or statistics as an amount of light capable of giving the same effect as when the light is blocked for the user's sleep time movement.

The lengths of the light irradiation period and the light blocking period may be determined according to the movement amount of the user's wake-up time or may be determined according to the user's input. In addition, the light irradiation period and the light blocking period may be set during other times than before and after the elevation time according to the user's input or the user's life pattern learned in the electronic device 101 . For example, the electronic device 101 may derive a spare time according to the learned life pattern of the user, and set at least one of a light irradiation period or a light blocking period for light therapy in the derived spare time.

Accordingly, the first light irradiation period 611 is set after the expected sleep time 601 on the first day, and the second light irradiation period 612 and the third light irradiation period 613 are the expected sleep time on the second and third days. It may be set after sleep time (602, 603). In addition, the first light blocking period 621 is set before the expected sleep time 601 on the first day, and the second light blocking period 622 and the third light blocking period 623 are the expected sleep time on the second and third days. It may be set before sleep time (602, 603). However, since it is impossible to accurately predict the actual user's sleeping time, the first light blocking period 621 may be set based on the average sleeping time of the user.

In addition, although not shown, in order to delay the sleeping time, it may be effective to irradiate light to the user within a preset time before going to bed and block the light to the user within a preset time after the user wakes up. Hereinafter, an embodiment for advancing the sleep time will be described, but it is not limited thereto, and even when the sleep time is delayed, only the positions of the light irradiation section and the light blocking section are the opposite of the embodiment for advancing the sleep time. Only the rest of the steps can be performed in the same way.

In one embodiment, when the electronic device 101 enters a preset light blocking section or light irradiation section, the light source of the electronic device 101 or the light source of the light irradiation device 120 is automatically blocked or irradiated with light. It may be controlled or notified to the user that the light blocking section or the light irradiation section has been entered through vibration, sound, voice, or message.

The predicted sleep time on day 2 602 and the expected sleep time on day 3 603 may be set based on the expected sleep time on day 1 601 according to the movement amount of wake-up time per determined number of light irradiations. For example, the expected sleep time on day 2 602 is set from 7:00 to 14:00, which is 2 hours ahead of the expected sleep time on day 1 601, and the expected sleep time on day 3 603 is the expected sleep time on day 1 ( 601) can be set from 5:00 to 12:00, which is 4 hours ahead.

In one embodiment, the intensity of the light emitted in the light irradiation sections 611, 612, and 613 and the irradiation time of the light are determined as the intensity of the first light according to previously stored information about the relationship between the amount of light and the moving amount at wake-up time, and the irradiation of light The time may be determined as 1 hour.

As described above, the electronic device 101 may create a light therapy schedule to move the user's wake-up time to the target wake-up time by the target date.

According to various embodiments of the present disclosure, the electronic device 101 may correct the generated light therapy schedule according to the characteristics of the user. Referring to FIG. 6B , the electronic device 101 provides the user with a first light irradiation section 611 after the user wakes up after sleeping on the first day according to the light treatment schedule generated as shown in FIG. 6A. The light source of the electronic device 101 or the light source of the light irradiation device 120 may be controlled so that light is irradiated for 1 hour with 1 light intensity. If the above-described information on the relationship between the light amount and the movement amount at wake-up time is not updated to suit the user's characteristics, the light is emitted to the user for the first time with the first light intensity determined according to the information on the relationship between the light amount and the movement amount at wake-up time. Even if it is irradiated to , the user's wake-up time may not move by an expected amount. Since each user may have different physical characteristics such as sensitivity to light and circadian rhythm, information on the relationship between the amount of light set according to general standards and the amount of movement at the time of waking up does not allow light therapy to be performed to suit the user's characteristics. may not be

Accordingly, the light treatment schedule needs to be corrected to match the characteristics of the user. To this end, the electronic device 101 may correct the light treatment schedule by using the first wake-up time obtained according to the actual sleeping time of the user on the second day. The electronic device 101 may obtain the first wake-up time and correct the light treatment schedule according to the obtained first wake-up time before irradiating light to the user in the second light irradiation section 612 . In this way, before irradiating light to the user, the electronic device 101 checks whether the light treatment schedule is suitable for the user, and according to the check result, the light treatment schedule may be maintained or the light treatment schedule may be corrected. . Hereinafter, a case in which the electronic device 101 corrects the light treatment schedule will be described.

According to an embodiment, the electronic device 101 may re-determine a movement amount of the wake-up time per number of times of irradiation of light irradiated to the user, based on the first wake-up time acquisition date, the target date, and the target wake-up time. As shown in FIG. 6B, in the light therapy schedule, light was irradiated with the first light intensity for 1 hour in the first light irradiation period 611 of the first day (DAY 1) in order to advance the user's wake-up time by 2 hours. On the second day (DAY 2), the user's wake-up time advances by only 1 hour, so the first wake-up time may be 16:00.

Accordingly, the electronic device 101 may correct the light treatment schedule based on the first wake-up time. For example, the electronic device 101 may re-determine the adjustment amount of the wake-up time per number of light irradiation times in order to move the first wake-up time to the target wake-up time of 11:00. Since light is irradiated once in the first light irradiation period 611, the remaining number of light irradiations until the target date may be two times. Accordingly, the amount of control of the wake-up time per number of times of light irradiation may be equally determined to be 2 hours and 30 minutes for each number of times of light irradiation, and as shown in FIG. 6B, 3 hours on the second day and 2 hours on the third day, respectively. may be determined. Hereinafter, it is assumed that the movement amount of the wake-up time per number of times of light irradiation is determined as 3 hours on the 2nd day and 2 hours on the 3rd day.

The electronic device 101 determines the intensity and intensity of light irradiated to the user based on the shift amount of the determined light irradiation number and the difference between the first wake-up time and the second wake-up time, which is the wake-up time on the first day (DAY 1). At least one of the irradiation times may be determined again. The electronic device 101 may update information about the relationship between the amount of light and the amount of movement of the time of waking up to suit the user, based on the result that the user's waking up time is advanced by 1 hour as a result of irradiating light at the first light intensity for 1 hour. can

The electronic device 101 sets the light intensity higher than the first light intensity in order to advance the user's wake-up time by 3 hours in the second light irradiation section 612 according to the information on the relationship between the updated amount of light and the movement amount of the time to wake up. The intensity of the light irradiated to the user may be determined again so that the light is irradiated for 1 hour with the third light intensity tripled. Also, the electronic device 101 may re-determine the light irradiation time so that the light is irradiated for 3 hours with the first light intensity. In addition, the electronic device 101 may re-determine both the light intensity and the light irradiation time so that the light is irradiated for 1.5 hours with a second light intensity twice the light intensity of the first light intensity. In this way, the electronic device 101 applies information about the relationship between the amount of light and the amount of movement at the time of waking up to the user based on the result that the user's waking up time is advanced by 1 hour as a result of irradiating light with the first light intensity for 1 hour. and at least one of the amount of light irradiated to the user or the irradiation time may be determined again according to the updated information.

In the above, for convenience of explanation, it has been described that the relationship between the intensity of light and the irradiation time of light is inversely proportional to irradiation with a specific amount of light, but is not limited thereto. The relationship between the intensity of light for irradiating light with a specific amount of light and the irradiation time of light may be determined based on actual experimental results or statistical data.

Also, the electronic device 101 may adjust the number of light irradiation to move the user's wake-up time to the target wake-up time. For example, as described above, the electronic device 101 may re-determine at least one of light intensity or light irradiation time, and perform light therapy on the target date DAY4, so that the next day of the target date DAY4 is The phototherapy schedule may be corrected so that the wake-up time of the user is moved to the target wake-up time by the fifth day (DAY5).

As described above, the electronic device 101 may correct the light treatment schedule to move the user's wake-up time according to the user's characteristics. Through this, the electronic device 101 can perform light therapy suitable for the user's characteristics.

7 is a flowchart of a method of determining at least one of an intensity of light or an irradiation time of light irradiated to a user by an electronic device according to various embodiments of the present disclosure.

7 describes a method in which the electronic device 101 determines whether to correct the phototherapy schedule according to the user's wake-up time obtained while the electronic device 101 performs phototherapy according to the generated phototherapy schedule. . Since it is determined that the electronic device 101 corrects the light treatment schedule, a specific method of correcting the light treatment schedule is the same as the above description, and thus a detailed description thereof will be omitted.

In step 710, the electronic device 101 may compare the obtained wake-up time of the user with the predicted wake-up time. The expected wake-up time may be the wake-up time of a user expected to move when light is irradiated for a specific time with an intensity of light determined according to information about a relationship between the amount of light stored in the electronic device 101 and the amount of movement at the wake-up time.

In step 720, the electronic device 101 may determine whether a difference between the user's wake-up time and the expected wake-up time is equal to or greater than a preset threshold. The threshold may be set in consideration of an error occurring in obtaining the user's wake-up time.

In step 730, when the difference between the user's wake-up time and the predicted wake-up time is equal to or greater than a threshold value, the electronic device 101 may update and store information about the relationship between the amount of light and the movement amount at the wake-up time.

In step 740, the electronic device 101 may re-determine at least one of the intensity of the light irradiated to the user or the irradiation time of the light according to the information about the relationship between the updated amount of light and the movement amount at the wake-up time.

In step 750, the electronic device 101 may maintain the current light intensity and light irradiation time when the difference between the user's wake-up time and the predicted wake-up time is less than a threshold value.

8A and 8B are flowcharts of a method of correcting a light treatment schedule according to biometric information of a user related to sleep by an electronic device according to various embodiments of the present disclosure.

According to various embodiments of the present disclosure, the electronic device 101 may correct the light treatment schedule according to the user's biometric information related to sleep as well as the user's characteristics. In FIGS. 8A and 8B , a method of correcting a phototherapy schedule according to the user's biological information related to sleep by the electronic device 101 will be described.

In operation 810, the electronic device 101 may calculate a movement amount of the user's wake-up time actually moved by the light irradiated according to the light treatment schedule according to the obtained user's wake-up time. As shown in FIG. 8B , the electronic device 101 compares the user's wake-up time 870 obtained on the current day with the most recently obtained user's wake-up time 860, so that the user actually moved by the irradiated light. It is possible to calculate the time-to-wake movement amount of . Hereinafter, for convenience of explanation, it is assumed that the actually moved user's wake-up time is 2 hours.

In step 820, the electronic device 101 may obtain biometric information related to the user's sleep. Biometric information related to the user's sleep may be as shown in Table 1. The electronic device 101 may obtain sleep-related biometric information through a sensor of the electronic device 101 or may receive sleep-related biometric information from the external electronic device 110 .

In step 830, the electronic device 101 may determine whether or not the user's physical symptoms appear due to insufficient sleep by using the acquired biometric information related to the user's sleep. The electronic device 101 may determine whether a physical symptom caused by insufficient sleep, such as drowsiness or fatigue, occurs even when the user wakes up from sleep, using the biometric information related to sleep.

In step 840, the electronic device 101 corrects the movement amount of the actually moved user's wake-up time calculated in step 810 when occurrence of the user's physical symptoms caused by not getting enough sleep continues over a certain frequency or over a certain period of time. can do. The electronic device 101 may determine that the user's wake-up time has not completely shifted when the user's physical symptoms caused by not getting enough sleep do not occur temporarily, but persist more than a certain frequency or a certain amount of time. Accordingly, the electronic device 101 may correct the movement amount calculated in step 810 at the wake-up time of the actually moved user.

For example, as shown in FIG. 8B , the electronic device 101 may determine whether or not the user's physical symptoms appear due to insufficient sleep according to the acquired biometric information related to the user's sleep. The electronic device 101 may correct the movement amount of the user's actual wake-up time to 1 hour instead of 2 hours, when the identified user's physical symptom persists at a predetermined frequency or more or for a predetermined period of time or longer. Accordingly, the electronic device 101 may correct the user's obtained wake-up time 870 as the user's wake-up time 871 by one hour.

In addition, in one embodiment, the electronic device 101 may determine a correction amount of the user's wake-up time according to the degree of the physical symptom. The electronic device 101 may classify the degree of the physical symptom according to the occurrence frequency or duration of the physical symptom. The electronic device 101 may check the occurrence frequency or duration of the physical symptoms according to the acquired biometric information of the user related to sleep, and determine the degree of the physical symptoms according to the check result. The electronic device 101 may determine a corrected amount of the user's wake-up time according to the degree of the determined physical symptom. For example, as shown in FIG. 8B, the electronic device 101 does not uniformly determine the correction amount of the wake-up time as 1 hour, but when the electronic device 101 determines that the degree of the physical symptom is low, 30 minutes may be determined, and if it is determined that the degree of physical symptoms is high, the wake-up time correction amount may be determined to be 1 hour and 30 minutes.

In step 850, the electronic device 101 may correct the light treatment schedule according to the shift amount of the corrected wake-up time in step 840. The electronic device 101 may recalculate a time-of-wake-up movement amount to be adjusted to the target time of wake-up according to the corrected time-of-wake-up movement amount, and correct the light treatment schedule according to the recalculated time-of-wake movement amount. Since a specific method of correcting the phototherapy schedule is the same as the method of generating and correcting the phototherapy schedule described above, a separate description thereof will be omitted.

9 is a flowchart of a method of correcting a phototherapy schedule based on biometric information of a user by an electronic device according to various embodiments of the present disclosure.

According to various embodiments of the present disclosure, the electronic device 101 may correct a phototherapy schedule by canceling or changing a predetermined phototherapy schedule according to the user's characteristics as well as the obtained biometric information of the user. In FIG. 9 , a method of correcting a phototherapy schedule by canceling or changing a predetermined phototherapy schedule according to the user's biometric information in the electronic device 101 will be described.

In step 910, the electronic device 101 may obtain biometric information (eg, body temperature, medicine prescription record, etc.) related to the user's physical condition. The electronic device 101 may obtain biometric information related to the user's physical condition through a sensor of the electronic device 101 or may receive biometric information related to the user's physical condition from the external electronic device 110 .

In step 920, the electronic device 101 may determine whether a change has occurred in the user's physical condition by using the acquired biometric information related to the user's physical condition. The electronic device 101 compares biometric information related to the user's physical condition with information related to the user's physical condition stored in the memory of the electronic device 101 to determine whether a change has occurred in the user's physical condition. .

In step 930, the electronic device 101 sets a phototherapy schedule scheduled for the current day according to the phototherapy schedule when the frequency of occurrence of changes in the user's physical condition is higher than or equal to a predetermined frequency or the change in the user's physical condition lasts for a predetermined period of time or longer. can be canceled Also, the electronic device 101 may cancel the light treatment schedule scheduled for the current day according to the light treatment schedule according to the user's request. Through this, it is possible to prevent a user from forcibly performing light therapy.

In step 940, the electronic device 101 may correct the light treatment schedule to adjust the user's wake-up time to the target wake-up time by the target date as the light treatment schedule scheduled for the current day is canceled in step 930. Since a specific method of correcting the phototherapy schedule is the same as the method of generating and correcting the phototherapy schedule described above, a separate description thereof will be omitted.

10 illustrates an electronic device displaying a light therapy notification according to a monitoring result of a user's wake-up time according to various embodiments of the present disclosure.

According to various embodiments of the present disclosure, the electronic device 101 may monitor the user's wake-up time by sensing information for determining the user's wake-up time, such as the user's biometric information or the user's movement information obtained through a sensor. can In addition, the electronic device 101 may monitor the user's wake-up time according to information about the user's wake-up time through the external electronic device 110 .

The electronic device 101 may determine whether the monitored user's wake-up time differs from the usual user's wake-up time or the average user's wake-up time by a preset threshold or more. The electronic device 101 may determine the monitored user's wake-up time as an abnormal wake-up time when the difference between the monitored user's wake-up time and the user's average wake-up time is greater than a preset threshold. The electronic device 101 may provide the user with a light therapy notification indicating that light therapy is required if the abnormal wake-up time lasts for a predetermined number of days or more. In addition, when the electronic device 101 receives an input for generating a light treatment schedule from the user as it provides a light treatment notification to the user, the electronic device 101 may generate a light treatment schedule for moving the abnormal wake-up time to the user's average wake-up time. there is. In addition, the electronic device 101 may generate a phototherapy schedule without receiving a separate input while providing a phototherapy notification to the user. Since a specific method of generating the light treatment schedule is the same as the method of generating the light treatment schedule described above, a separate description thereof will be omitted.

For example, as shown in FIG. 10 , when the abnormal wake-up time lasts for 3 days or more, the electronic device 101 may provide a light therapy notification 1020 to the user 3 days after the occurrence of the abnormal wake-up time. The light therapy notification 1020 may be displayed in the form of a message as shown in FIG. 10 or output through voice. In addition, the electronic device 101 may display a wake-up time change pattern in a graph 1010 so that the user can recognize the wake-up time change while providing a light therapy notification 1020 . When the electronic device 101 receives a user input of touching the “settings” menu included in the light therapy notification 1020, the electronic device 101 may create a light therapy schedule to move the abnormal wake-up time to the user's average wake-up time. .

In addition, although a case in which the wake-up time is delayed is illustrated in FIG. 10 , the present invention is not limited thereto, and the electronic device 101 displays through a graph that the wake-up time is advancing even when the wake-up time advances, and notifies the light treatment. can provide.

11 is a diagram for explaining a method of controlling a light source of an electronic device according to various embodiments of the present disclosure.

According to various embodiments of the present disclosure, the electronic device 101 may control a light source of the electronic device 101 according to the generated light treatment schedule to emit light to the user.

In one embodiment, as shown in (a) of FIG. 11 , the light source may emit light at a first light irradiation angle (θ ₁ ) 1110 so that the light is irradiated throughout the space where the user is located. However, in this case, since it may affect other people located in the same space as the user, the electronic device 101 may control the light source so that the light is focused on the user by adjusting the light irradiation angle.

For example, as shown in (b) of FIG. 11 , the electronic device 101 may track the user's gaze through a photographing module (eg, a camera, etc.) included in the electronic device 101 . Accordingly, as shown in (c) of FIG. 11 , the electronic device 101 sets the light irradiation angle from the first light irradiation angle θ ₁ 1110 to the second light irradiation angle so that light can be concentrated on both eyes 1120 of the user. It can be adjusted by the light irradiation angle (θ ₂ ) (1111). In addition, as shown in (d) of FIG. 11 , when the electronic device 101 includes a refractive lens, the electronic device 101 maintains the first light irradiation angle (θ ₁ ) 1110 as the light irradiation angle. , the refractive lens may be adjusted so that the light can be concentrated on both eyes 1120 of the user.

Through this, as shown in (e) of FIG. 11 , the electronic device 101 may control the light source so that the light is concentrated on the user's both eyes 1120 instead of emitting light to the entire space where the user is located. Accordingly, the user can perform light therapy through the electronic device 101 without worrying about the effect on others. In addition, the electronic device 101 may control the light irradiation angle of the light source as described above to increase the intensity of the light by concentrating the light on the user in the light irradiation section.

12 is a diagram for explaining a method of controlling light irradiation devices according to a user's location by an electronic device according to various embodiments of the present disclosure.

According to various embodiments of the present disclosure, the electronic device 101 may determine a user's location in a building and determine a light irradiation device for radiating light to the user according to the identified user's location.

As shown in FIG. 12 , the electronic device 101 confirms that the user is located in the first space 1210 in the building, and uses the first light irradiation device located in the first space 1210 to emit light to the user. It can be determined by the irradiation device. The electronic device 101 includes a command for controlling a light source of the first light irradiation device based on information on at least one of light intensity or light irradiation time included in a light treatment schedule generated by the first light irradiation device. control signals can be transmitted. The electronic device 101 may control the light source of the first light irradiation device by transmitting the control signal to the first light irradiation device.

In addition, when the user moves from the first space 1210 to the second space 1211 within the building, the electronic device 101 checks the user's movement, and the second light irradiation device located in the second space 1211 may be determined as a light irradiation device for irradiating light to a user. The electronic device 101 includes a command for controlling a light source of the second light irradiation device based on information on at least one of light intensity or light irradiation time included in a light treatment schedule generated by the second light irradiation device. control signals can be transmitted. The electronic device 101 may control the light source of the second light irradiation device by transmitting the control signal to the second light irradiation device.

In addition, the electronic device 101 learns the user's movement pattern within the building according to the identified user's location within the building, and the light irradiation device within the building even if the user's location is not separately identified according to the learned user's movement pattern within the building. can also control them. For example, the electronic device 101 learns a user's main travel path before going to sleep or after waking up, and even if the user's location is not separately checked according to the learned user's travel path, the electronic device 101 determines the learned travel path.
