Description

The present invention relates to an awakening device that adjusts an indoor environment for awakening.

Patent Literature 1 discloses a sleep support device that predicts the sleep depth of a user at a scheduled time to get up and adjusts the indoor environment. For example, the sleep state of the user is determined based on the blood pressure change and the body temperature change of the user. The depth of sleep has a cycle, and light sleep and deep sleep are normally repeated alternately. Awakening comfort of the user is affected by the depth of sleep before waking up. If the sleep before awakening is light, the user wakes up well. If the sleep before the awakening is deep, the user feels lack of sleep. The sleep support device predicts the sleep state of the user at the wake-up time. If the predicted sleep state is a light sleep, the sleep support device maintains the lighting device in a lighting stop state, for example. If the predicted sleep state is deep sleep, the sleep support device lights the lighting device, for example, 15 minutes before the wake-up time.

JP, 2017-113454, A

In the sleep support device described in Patent Document 1, the indoor environment is adjusted during a preset wake-up preparation period so that sleep at the scheduled wake-up time becomes light. Therefore, depending on the depth of sleep of the user, the user awakens by being rapidly induced from deep sleep to light sleep in a shorter time than the sleep cycle of the user. As a result, the user is in a state where he/she wakes up rapidly from deep sleep, and may feel a lack of sleep.

The present invention has been made in view of the above-mentioned circumstances, and a period in which the indoor environment for awakening is adjusted according to the depth of sleep before awakening so that the user can wake up clearly. To provide a device.

(1) An awakening device according to the present invention includes a sensor that detects a user's sleeping motion, an indoor environment adjustment device that adjusts the indoor environment in which the user sleeps, and a control unit. The control unit is a reception process that receives a scheduled wake-up time, a cycle determination process that determines a cycle of the sleep depth of the user based on the output of the sensor, and a predetermined sleep depth in the determined cycle. Estimated time, the scheduled wake-up time, a time difference determination process for determining the time difference between, and according to the determined time difference, the environment adjustment process for adjusting the output of the indoor environment adjustment device before the scheduled wake-up time, Execute.

By determining the time difference between the estimated time that is the predetermined sleep depth and the scheduled wakeup time, the setting of the indoor environment adjustment device can be changed based on the time difference, and is suitable for the cycle of the sleep depth of the user. It is possible to provide an indoor environment for awakening.

(2) Preferably, the estimated time is a time at which the time difference is the shortest among the times at which sleep becomes the lightest in the determined cycle. The control unit determines whether the estimated time belongs to a first range, a second range, or a third range; and the estimated time is one of the first range to the third range. In response to the determination that the crab belongs, the selection process for selecting the corresponding wake-up preparation period, and the environment adjustment process after the selection process are performed. The first range, the second range, and the third range are time ranges that do not overlap with each other. The first range is a range before the scheduled wake-up time, the second range is a range after the first range and includes the scheduled wake-up time, and the third range is the wake-up time. The range is after the scheduled time and after the second range.

(3) Preferably, in the selection process, the wake-up preparation period is set to the first time and the estimated time belongs to the second range in response to the determination that the estimated time belongs to the first range. According to the determination, the wake-up preparation period is set to a second time shorter than the first time, and the wake-up preparation period is set to the first time according to the determination that the estimated time belongs to the third range. It will be the longer third time.

(4) For example, the estimated time is the time at which the time difference is the shortest among the times at which sleep becomes deepest in the determined cycle. The control unit performs a range determination process of determining whether the estimated time belongs to the first range, the second range, the third range, or the fourth range, and the estimated time from the first range to the third range. In response to the determination that it belongs to one of the ranges, a selection process for selecting a corresponding wake-up preparation period, and the environment adjustment process after the selection process are performed. The first range, the second range, the third range, and the fourth range are divided time ranges without overlapping each other. The first range is a range before the scheduled wake-up time, the second range is a range after the first range and up to the scheduled wake-up time, and the third range is the third range. It is a range after the second range and before the fourth range, and the fourth range is a range after the third range.

(5) For example, in the selection process, the wake-up preparation period is set to the first time and the estimated time is set to the first range or the fourth range in response to the determination that the estimated time belongs to the third range. The wake-up preparation period is set to a second time shorter than the first time in response to the determination that the wake-up preparation period belongs to the range, and the wake-up preparation period is set to the second wake-up preparation period determined to be determined to belong to the second range. The third time is longer than the first time.

(6) For example, the first range, the second range, and the third range are obtained by dividing a range of time that is before and after the scheduled wake-up time by 1/2 cycle of the determined cycle.

Depending on the estimated time, it is possible to provide an indoor environment for awakening that is suitable for the sleep cycle of the user.

(7) Preferably, the sensor detects the operation in a non-contact manner.

Since the sensor detects the movement of the user in a non-contact manner, the sleep of the user is not disturbed.

(8) For example, the indoor environment adjusting device includes at least one of a lighting fixture, an air conditioner, an audio device, and an aroma diffuser.

(9) The program according to the present invention can be executed by a computer of an awakening device, which includes a sensor that detects a user's sleeping motion and an indoor environment adjusting device that adjusts an indoor environment in which the user sleeps. A reception process that receives a scheduled wake-up time, a cycle determination process that determines a cycle of the sleep depth of the user based on the output of the sensor, an estimated time that is a predetermined sleep depth in the determined cycle, and A time difference determination process of determining a time difference between the scheduled wake-up time and an environment adjustment process of adjusting the output of the indoor environment adjustment device before the scheduled wake-up time according to the determined time difference, and causing the computer to execute the process. ..

(10) Preferably, the estimated time is a time at which the time difference is the shortest among the times at which sleep becomes the lightest in the determined cycle. Range determination processing for determining whether the estimated time belongs to the first range, the second range, or the third range, and determining that the estimated time belongs to any of the first range to the third range In response to this, the computer is caused to execute the selection processing for selecting the corresponding wake-up preparation period and the environment adjustment processing after the selection processing is executed. The first range, the second range, and the third range are time ranges that do not overlap with each other. The first range is a range before the scheduled wake-up time, the second range is a range after the first range and includes the scheduled wake-up time, and the third range is the wake-up time. The range is after the scheduled time and after the second range.

Hereinafter, embodiments of the present invention will be described. It is needless to say that the embodiment described below is merely an example of the present invention, and the embodiment of the present invention can be appropriately changed without changing the gist of the present invention.

[First Embodiment]
FIG. 1 is a schematic diagram of an awakening device 10 according to the first embodiment. As shown in FIG. 1, the awakening device 10 is mainly provided in a bedroom 11 in which a user sleeps. The awakening device 10 also includes a sensor 12, a clock 13, a mobile terminal device 14 such as a mobile phone or a smart phone, a controller 15, and an indoor environment adjusting device 16. The awakening device 10 adjusts the environment of the bedroom 11 when the user awakens from sleep.

The bedroom 11 is provided in, for example, a building where the user lives, but may be a living room or a reception room as long as the user sleeps. Further, it is not limited to the user's residence, and may be one room such as a hotel. The user sleeps on the bed 25 provided in the bedroom 11.

The bedroom 11 has, for example, a floor 21, a wall 22, a ceiling 23, a door (not shown), and a window 24 provided in the wall 22. In addition, a bed 25, a sensor 12, a clock 13, a mobile terminal device 14, and an indoor environment adjusting device 16 are installed in the bedroom 11. The clock 13 and the mobile terminal device 14 may be carried by the user and taken out of the bedroom 11.

The sensor 12 is a Doppler sensor that detects biological information. Further, the sensor 12 may be, for example, a pressure sensor installed under the mattress as long as it can detect biological information. Further, the sensor 12 may be a wearable sensor that is wrapped around the user's arm or the like or attached to the body or the like. The sensor 12 irradiates a living body with a microwave, receives a reflected wave of the irradiated microwave, and detects a movement of a body surface based on a frequency difference between the irradiated microwave and the received microwave. The sensor 12 outputs a signal according to the movement of the body surface.

The mobile terminal device 14 may have an input unit through which the user can input the scheduled wakeup time 35. The input unit is, for example, a key or a touch screen. Further, instead of the mobile terminal device 14, the clock 13 may be provided with an input unit. When the mobile terminal device 14 receives an input of the scheduled wakeup time from the user, the mobile terminal device 14 transmits a signal indicating the input scheduled wakeup time to the controller 15.

The clock 13 is a so-called clock. The clock 13 may be a table clock, a wall clock, or a wristwatch. The clock 13 may be integrated with the mobile terminal device 14 or the controller 15, or may be another device capable of receiving time information from the outside. The clock 13 sends time information indicating the current time to the controller 15.

The controller 15 functions as a so-called server, and may be installed in a building having the bedroom 11 or may be installed in a place different from the building having the bedroom 11. As shown in FIG. 2, the controller 15 has a CPU 31 and a memory 32. Although not shown in FIG. 2, the controller 15 has an interface for communicating information with the sensor 12, the mobile terminal device 14, and the clock 13. The memory 32 stores the program 33. The CPU 31 reads the program 33 and information stored in the memory 32 and performs each process. The controller 15 outputs a signal for adjusting the output to the indoor environment adjusting device 16. The controller 15 is an example of a computer.

The program 33 is for executing, for example, a process of determining the sleep depth of the user, a process of selecting a wake-up preparation period, and a process of adjusting the output of the indoor environment adjusting device 16. For example, respiration, heartbeat and body movement are obtained by analyzing signals received from the sensor 12. Although a known method is used for this analysis, respiration and heartbeat are obtained by, for example, frequency-analyzing the signal. The body movement is obtained, for example, from the number of times the amplitude of the signal becomes equal to or larger than the threshold value.

The indoor environment adjusting device 16 receives the signal output from the controller 15 and adjusts the indoor environment based on the information of the signal. The indoor environment adjusting device 16 includes a lighting device 41, an air conditioning device 42, an audio device 43, and an aroma diffuser 44. The indoor environment adjusting device 16 may include any one of the lighting equipment 41, the air conditioning equipment 42, the audio equipment 43, and the aroma diffuser 44. Further, the speaker included in the mobile terminal device 14 may function as an audio device of the indoor environment adjusting device 16.

Hereinafter, the operation of the controller 15 according to the present embodiment will be described with reference to FIGS. 3 to 7.

The controller 15 performs information collection processing to acquire the scheduled wake-up time 35 stored in the memory 32, time information, and the user's breathing, heartbeat, and body movement (S11). The scheduled wake-up time 35 is input to the mobile terminal device 14 by the user and transmitted to the controller 15. The controller 15 stores the received scheduled wake-up time 35 in the memory 32. Further, the controller 15 periodically acquires time information, which is the current time, from the clock 13. The controller 15 determines whether the user is in the bed 25 based on the signal output by the sensor 12. For example, the controller 15 determines that the user is in the bed 25 when the signal output from the sensor 12 is equal to or higher than the output capable of detecting respiration, heartbeat, and body movement.

The controller 15 periodically acquires the signal output by the sensor 12 in response to determining that a person is in the bed 25, and determines the user's respiration, heartbeat, and body motion based on the acquired signal, The sleep depth of the user is determined for each unit time according to the acquisition of the signal (S12). Known methods are used for the method of determining respiration, heartbeat, and body movement from the signal output by the sensor 12, and the method of determining the depth of sleep. Further, the cycle in which the controller 15 acquires the signal output by the sensor 12 is, for example, about 1 to 5 minutes.

The depth of sleep is divided into non-REM sleep and REM sleep. Non-REM sleep is divided into stages 1 to 4 according to the depth of sleep, for example. There are cycles in the depth of sleep. In the sleep depth cycle, normally, non-REM sleep and REM sleep are alternately repeated. In the case of an adult, the depth of sleep during non-REM sleep generally becomes deeper in the order of step 1 to step 4 after falling asleep and reaches step 4 within about 1 hour after falling asleep. The sleep depth becomes shallower after stage 4, and becomes REM sleep after stage 1. The sleep depth of the stage 1 is shallower than that of the other stages 2 to 4, for example. The depth of sleep of REM sleep is shallower than that of non-REM sleep. The REM sleep is repeated 3 to 5 times when, for example, the sleep time from falling asleep to waking up is 6 to 8 hours and the length of one cycle of the sleep depth cycle is 90 minutes.

Stage 1 may be extracted by the number of body movements per unit time. The number of body movements tends to increase in stage 1 before and after REM sleep, particularly in stage 1 immediately after REM sleep. The lightest sleep may be extracted by stage 1 detection with increasing number of body movements. When REM sleep can be extracted by breathing or heartbeat other than body movement, or a combination thereof, REM sleep may be determined as the lightest sleep. That is, the lightest sleep may be grasped as the stage 1 or the REM sleep in the non-REM sleep. The controller 15 records the time when the signal is obtained from the sensor 12 and the signal of the sensor 12 or respiration, heartbeat, body movement, etc. based on the signal of the sensor 12 in the memory 32 (S13).

The controller 15 determines whether the current time has reached a preset time X before the scheduled wake-up time 35 (S14). The scheduled time X may be preset as a default in the program, or may be the time changed by the user. It is preferable that the scheduled time X corresponds to, for example, half of the general time for one cycle of the sleep depth cycle. In the present embodiment, the scheduled time X is set to 45 minutes before the scheduled wake-up time, for example.

The controller 15 performs the cycle determination process in response to the determination that the current time has reached the scheduled time X (S14: Yes) (S15). As shown in FIG. 4, in the cycle determining process, the controller 15 determines the reference time T (S21). As shown in FIG. 6, the reference time T is the time when the sleep becomes the lightest, that is, the time when the sleep is the stage 1 or the REM sleep, and the time which is the closest to the scheduled time X.

Further, as shown in FIG. 4, the controller 15 obtains the average time ta for one cycle of the sleep depth cycle (S22). As shown in FIG. 6, since the depth of sleep changes periodically, the time to be in stage 1 or REM sleep from the fall asleep to the scheduled time X is a plurality of periodic times. Then, the interval from a certain reference time T to the time when the last sleep becomes the lightest, that is, the time when the sleep is the stage 1 or the REM sleep is calculated as the time tk of one cycle. From the reference time T to the sleep onset time of the user, the intervals (time of one cycle) of the time when the sleep becomes the lightest (step 1 or the time when it becomes REM sleep) are t1 and t2 in the order from the reference time T to the sleep onset time, respectively. .., tn, the average time ta in one cycle is (t1+t2+...+tn)/n.

As shown in FIG. 3, the controller 15 determines the estimated time T1 (S16). The estimated time T1 is a time at which the time difference from the scheduled wake-up time 35 is the shortest except before the scheduled time X, and the sleep is estimated to be the lightest (stage 1 or REM sleep). Even from the scheduled time X to the scheduled wake-up time, the sleep depth of the user changes periodically. Since the scheduled time X is half the time of one cycle of general sleep, the time at which the cycle becomes Stage 1 or REM sleep after one cycle has passed from the estimated time T1 is the time at which it becomes Stage 1 or REM sleep. It can be estimated that the time difference with the scheduled wake-up time 35 is the shortest. Therefore, the controller 15 determines the time obtained by adding the average time ta to the reference time T as the estimated time T1.

The controller 15 that has determined the estimated time T1 determines the time difference ΔT (S17). The time difference ΔT is a difference between the scheduled wake-up time 35 and the estimated time T1, and is a positive time when the estimated time T1 is after the scheduled wake-up time 35, and the estimated time T1 is before the scheduled wake-up time 35. It is a negative time at one time. That is, the time difference ΔT is the time obtained by subtracting the estimated time T1 from the scheduled wakeup time 35. The time difference ΔT is −45 minutes or more. When the average time ta is 90 minutes, the time difference ΔT is in the range of −45 minutes to 45 minutes.

The controller 15 that has determined the time difference ΔT performs range determination processing (S18). As shown in FIG. 5, in the range determination process, the controller 15 uses the time difference ΔT to determine which time range before and after the estimated wake-up time 35 belongs to the estimated time T1. As shown in FIG. 7, as the time range before and after the scheduled wake-up time 35, three ranges from the first range 51 to the third range 53 are set in advance and stored in the memory 32. The first range 51 is, for example, a range of time from -45 minutes to -23 minutes before the scheduled wake-up time 35. That is, the range is from 45 minutes before the scheduled wake-up time 35 to 23 minutes before. The second range 52 is, for example, a range of time after the elapse of the first range 51 and before +23 minutes. That is, the range is from 23 minutes before the scheduled wake-up time 35 to 23 minutes after the scheduled wake-up time 35. The third range 53 is, for example, a range of time after the second range 52 has elapsed. That is, it is 23 minutes after the scheduled wake-up time 35. The first range 51 may be longer or shorter, but the boundary time with the second range 52 is preferably 45 minutes before the scheduled wake-up time 35 and the scheduled wake-up time 35. The second range 52 may be longer or shorter, but preferably includes the scheduled wake-up time 35. The third range 53 may be longer or shorter, but it is preferable that the boundary time with the second range 52 is between the scheduled wake-up time 35 and half a half hour later.

As illustrated in FIG. 5, the controller 15 determines that the estimated time T1 belongs to the first range 51 (S31: first range), and accordingly, the first selection that sets the wake-up preparation period to the first time 55. The process is executed (S32). As shown in FIG. 7, the wake-up preparation period is a period in which the user adjusts the indoor environment for waking up from sleep. The first time 55 is, for example, the time from 23 minutes before the scheduled wake-up time 35 to the scheduled wake-up time 35.

As shown in FIG. 5, the controller 15 determines that the estimated time T1 belongs to the second range 52 (S31: second range), and then selects the second time 56 as the wakeup preparation period. The process is executed (S33). As shown in FIG. 7, the second time 56 is, for example, the time from 15 minutes before the scheduled wake-up time 35 to the scheduled wake-up time 35.

As shown in FIG. 5, the controller 15 determines that the estimated time T1 belongs to the third range 53 (S31: third range), and accordingly the third selection in which the wake-up preparation period is the third time 57. The process is executed (S34). As shown in FIG. 7, the third time 57 is, for example, a time from 45 minutes before the scheduled wake-up time 35 to the scheduled wake-up time 35.

The controller 15 that has executed the range determination process performs an environment adjustment process for adjusting the output of the indoor environment adjustment device 16 in response to determining that the current time has reached the wake-up preparation period (S19: Yes) (S20). .. In the environment adjustment process, the controller 15 adjusts the output of the indoor environment adjustment device 16. For example, the controller 15 turns on the lighting fixture 41 and adjusts the brightness thereof so as to gradually increase toward the preset 1000 lux in the wake-up preparation period. In general, sleep tends to become shallow as the brightness (lux) increases.

Similarly, the controller 15 is driven when the air conditioning equipment 42 is stopped. For example, the controller 15 selects cooling during the summer period and heating during the winter period. Then, the set temperature of the air conditioner 42 is gradually raised from the set temperature for both cooling and heating during the wake-up preparation period.

Similarly, the controller 15 operates the audio equipment 43 to adjust the volume so that the volume gradually increases toward the preset volume during the wake-up preparation period. Further, the controller 15 operates the aroma diffuser 44 and adjusts the odor that prompts awakening to be gradually released during the wake-up preparation period.

As described above, the controller 15 can adjust the output of each device of the indoor environment adjusting device 16 and give the user a stimulus to lighten the sleep of the user. Then, the controller 15 ends the process when the current time reaches the scheduled wake-up time 35. Further, the controller 15 may cause the clock 13, the mobile terminal device 14, or the audio device 43 to generate a sound set as an alarm sound when the current time reaches the scheduled wake-up time 35.

[Operation and effect of the first embodiment]
According to the awakening device 10, the setting of the indoor environment adjustment device 16 can be changed based on the time difference ΔT by determining the time difference ΔT between the estimated time when the sleep becomes the lightest and the scheduled wakeup time 35. As a result, it is possible to provide an indoor environment for awakening that is suitable for the sleep depth cycle of the user.

Further, according to the awakening device 10, it is possible to provide an indoor environment for awakening suitable for the sleep cycle of the user according to the estimated time.

Further, the sensor 12 does not interfere with the sleep of the user because the sensor 12 detects the user's motion without contacting the user. Further, since the sensor 12 is a Doppler sensor that uses microwaves, erroneous detection is less than that of a pressure sensor.

[Second Embodiment]
In the first embodiment 1, the first range 51 to the third range 53 are predetermined and stored in the memory 32 of the controller 15, but the first range 51 to the third range 53 are based on the average time ta. May be determined. In that case, the processing of the controller 15 is different in the same device configuration as the first embodiment. Therefore, in the second embodiment, description of the same device configuration as in the first embodiment will be omitted, and processing of the controller 15 different from that of the first embodiment will be described.

As shown in FIG. 8, the controller 15 starts the cycle determining process in response to the determination that the user has fallen asleep (S41: Yes) (S42). As shown in FIG. 9, the controller 15 determines the average time ta (S52: Yes) in response to determining that the time when the sleep becomes the lightest (the time of stage 1 or the REM sleep) is detected (S51: Yes) (S52). ). For example, when the time when the sleep becomes the lightest is first detected, the average time ta is the time from the falling asleep to the detected time.

The controller 15 determines whether the current time has reached the time Y in response to determining that the time when the sleep becomes the lightest (the time of the stage 1 or the REM sleep) is not detected (S51: No) ( S53). The time Y is calculated as a time that is half the average time ta before the scheduled wake-up time 35.

When the controller 15 determines that the current time has not reached the time Y (S53: No), the controller 15 performs the process of step S51. Therefore, the controller 15 continues to detect the time when sleep becomes the lightest until the current time reaches the time Y. Then, the controller 15 obtains the average time ta each time the time when sleep becomes the lightest is detected (S52).

Therefore, after falling asleep, the average time ta when the first time when the sleep becomes the lightest is detected is the time from the sleep time to the first time when the sleep becomes the lightest. Further, after falling asleep, the average time ta when the second time when the sleep becomes the lowest is detected is the time from the sleep time to the first time when the sleep becomes the lowest and the time from the time to the second time. And the average. In this way, the average time ta is updated every time the time when sleep becomes the lightest is detected. The time Y is also updated each time the average time ta is updated.

As shown in FIG. 9, the controller 15 determines the estimated time Y1 as shown in FIG. 8 in response to determining that the current time has reached the time Y (S53: Yes) (S43). .. The estimated time Y1 is the time obtained by adding the average time ta to the reference time T. The reference time T is a time immediately before time Y when sleep becomes the lightest. When the time when the sleep becomes the lightest is detected, the controller 15 repeatedly adds the updated average time ta until the time Y is reached from the detected time to obtain the reference time T. Then, the controller 15 calculates the estimated time Y1 by adding the average time ta to the calculated reference time T. The obtained estimated time Y1 is the time estimated to be the time when the sleep having the shortest time difference from the scheduled wakeup time 35 becomes the shallowest.

As shown in FIG. 8, the controller 15 determines the time difference ΔY by subtracting the estimated time Y1 from the scheduled wake-up time 35 (S44). The time difference ΔY has a value in the range of −ta/2 to ta/2.

The controller 15 that has determined the time difference ΔY performs range determination processing (S45). The range determination process is a process of determining to which time range around the estimated wake-up time 35 the estimated time Y1 belongs by using the time difference ΔY. The time before and after the scheduled wake-up time 35 is divided from the first range 51 to the third range 53. The first range 51 is, for example, a range of time from -ta/2 minutes to -ta/4 minutes before the scheduled wake-up time 35. The second range 52 is, for example, a range of time after the passage of the first range 51 and before +ta/4 minutes. The third range 53 is, for example, a range of time after the second range 52 has elapsed.

The first time 55 is, for example, the time from ta/4 before the scheduled wake-up time 35 to the scheduled wake-up time 35. The second time 56 is, for example, a time from ta/8 before the scheduled wake-up time 35 to the scheduled wake-up time 35. The third time 57 is, for example, a time from ta/2 before the scheduled wake-up time 35 to the scheduled wake-up time 35.

As illustrated in FIG. 10, the controller 15 determines that the estimated time T1 belongs to the first range 51 (S61: first range), and accordingly selects the first time 55 as the wakeup preparation period. The process is executed (S62). In addition, the controller 15 executes the second selection process in which the wake-up preparation period is the second time 56 in response to the determination that the estimated time T1 belongs to the second range 52 (S61: second range) (S63). ). In addition, the controller 15 executes the third selection process in which the wake-up preparation period is the third time 57 in response to determining that the estimated time T1 belongs to the third range 53 (S61: third range) (S64). ).

As illustrated in FIG. 8, the controller 15 that has executed the range determination process adjusts the output of the indoor environment adjustment device 16 in response to determining that the current time has reached the wake-up preparation period (S46: Yes). Environmental adjustment processing is performed (S47). Since the environment adjustment processing is the same as that of the first embodiment, detailed description is omitted here.

The second embodiment as described above also achieves the same effects as the first embodiment. In addition, since the wake-up preparation period has a length corresponding to the average time ta, the wake-up preparation period can have a length more suitable for the sleep cycle of the user. For example, the wake-up preparation period can be set to a length suitable for the user even if the time of one cycle is not a general length.

[Modification]
In each of the above-described embodiments, an example has been described in which each process is executed based on the time when sleep becomes the lightest. In this modification, each process may be executed based on the time when sleep becomes deepest, and an example of a range of time around the estimated wakeup time 35 to which the estimated time T1 or the estimated time Y1 belongs in this case will be described.

As shown in FIG. 12, the time before and after the scheduled wake-up time 35 is divided into the first range 51 to the fourth range 54. When the average time ta is 90 minutes, the first range 51 is, for example, a range from −45 minutes to −23 minutes before the scheduled wake-up time 35. The second range 52 is, for example, a range of time after the lapse of the first range 51 and before the scheduled wake-up time 35. The third range 53 is, for example, a range of time from the scheduled wake-up time 35 to 23 minutes after the scheduled wake-up time 35. The fourth range 54 is, for example, a range of time after the third range 53 has elapsed.

As illustrated in FIG. 11, the controller 15 determines that the estimated time T1 belongs to the first range 61 or the fourth range 64 (S71: first range or fourth range) and sets the wake-up preparation period. The second time is set to 56 (S73). In response to determining that the estimated time T1 belongs to the second range 62 (S71: second range), the controller 15 sets the wake-up preparation period to the third time 57 (S74). In response to determining that the estimated time T1 belongs to the third range 63 (S71: third range), the controller 15 sets the wake-up preparation period to the first time 55 (S72).

[Operation and effect of modification]
Even with such a modified example, the same operational effects as those of the above-described respective embodiments are exhibited. Further, the average time ta is obtained without using the sleep onset time. Therefore, even if the sleep onset time is erroneously detected, the wake-up preparation period can be suitable for the sleep cycle of the user.

(4) For example, the estimated time is the time at which the time difference is the shortest among the times at which sleep becomes deepest in the determined cycle. The control unit performs a range determination process of determining whether the estimated time belongs to the first range, the second range, the third range, or the fourth range, and the estimated time from the first range to the fourth range. In response to the determination that it belongs to one of the ranges, a selection process for selecting a corresponding wake-up preparation period, and the environment adjustment process after the selection process are performed. The first range, the second range, the third range, and the fourth range are divided time ranges without overlapping each other. The first range is a range before the scheduled wake-up time, the second range is a range after the first range and up to the scheduled wake-up time, and the third range is the third range. It is a range after the second range and before the fourth range, and the fourth range is a range after the third range.
