Description

  The present invention relates to a body wearing device with a sleep sensor that can be worn on a body equipped with a sleep sensor.

Conventionally, when a desired sleep desired time such as nap or sleep is designated, a time alarm technique is known in which an alarm sound or the like is notified that the wake-up time has arrived after the desired sleep time has elapsed.
It also detects changes in the sleep state of the body by detecting the pulse rate from a finger or the like using a pulse sensor, and alarms at the time obtained by integrating 90 minutes, which is a general sleep cycle, with a predetermined natural number after falling asleep. There has been proposed a technique in which a technique for awakening a sound is applied to a wristwatch (see, for example, Patent Document 1).
JP 2003-79588 A

However, since the time alarm technology does not consider the time from the start of going to bed until falling asleep, the actual sleep time is shorter than the desired sleep time. For this reason, there is a case where the time notified by an alarm sound or the like is not the optimal wake-up time, and there is a problem that it is impossible to wake up with a clean wake-up.
Moreover, even if the sleep cycle is 90 minutes and the wake-up time is notified with an alarm sound as in Patent Document 1, there are people who cannot wake up with a clean awakening because there are individual differences in the sleep cycle. End up. In addition, if you eat or exercise before going to bed, the sleep cycle and sleep state may vary compared to normal times, so even if you perform the same processing as normal times, you may wake up with a clean awakening There is a problem that you can not.

As shown in FIGS. 1 to 5 and the like, the wristwatch 100 with a sleep sensor includes a watch main body 1 and a body mounting portion 2 for mounting the watch main body 1 on an arm A. .

Among these, the body mounting portion 2 is extended from one end portion (for example, the right end portion in FIG. 2) of the watch body portion 1 and wound around the arm A as shown in FIGS. It is curved along the surface of the arm A.
In addition, at a predetermined position inside the body wearing part 2, for example, the wearing part side arm contact made of a shape memory low resilience material (for example, low resilience urethane) and deformed according to the shape of the surface of the arm A is used. Portions 21 and 21 are provided. Thereby, the adhesiveness with respect to the arm A of the wristwatch 100 with a sleep sensor can be improved (refer FIG. 2).

  The watch body 1 digitally displays, for example, the current time, the expected wake-up time, the expected wake-up time (see FIG. 3), and the like. Specifically, as shown in FIGS. 3 to 5 and the like, the timepiece main body 1 is provided with a timepiece case 11, a key switch portion 12 provided on a side surface of the timepiece main body 1 and having a plurality of switches, a timepiece A watch glass 13 attached to the upper end of the case 11, a display unit 14 provided on the arm A side (lower side in FIG. 4) from the watch glass 13 and having a digital display function, and an arm A than the display unit 14.

Further, the display unit 14 may display, for example, “1.30 minutes”, “2.45 minutes”, “3.60 minutes (1 hour)”, “4.75 minutes”, “5.90 minutes (1 hour and a half). ) ”,...,“ 10. N minutes (M hours) ”or the like, a desired sleep time selection screen g3 (see FIG. 15B) related to a selection instruction of the desired sleep time that the user wants to take a nap or sleep is displayed. To do.

  Further, the display unit 14 displays a first expected wake-up screen g41 (see FIG. 15C) that includes the predicted wake-up time and the predicted wake-up time calculated in the expected wake-up time calculation process, and an expected wake-up time specifying process. A predicted wake-up screen g4 such as a second predicted wake-up screen g42 (see FIG. 18 (b)) including the predicted wake-up time specified in step (b) and a predicted wake-up state comment is displayed. Therefore, the display unit 14 constitutes a notification control unit that notifies the expected wake-up time and the expected wake-up time before going to bed.

  The display unit 14 is provided with light emitting means such as a light emitting diode (not shown), for example, so that the display unit 14 is irradiated with light and darkened. Even in places, the user can visually recognize information such as the current time.

  The clock module 15 includes, for example, a clock unit 151 that counts signals input from an oscillation unit (not shown) that constantly outputs a signal with a constant frequency and acquires current time data and the like. The current time data and the like acquired by the time measuring unit 151 are output to the CPU 161.

  As shown in FIG. 5, for example, the key switch unit 12 includes a mode setting switch 121, a sleep switch 122, a wake-up switch 123, a selection switch 124, a determination switch 125, and the like. These switch operation signals are output to the CPU 161.

The bedtime switch 122 is a switch that is operated when the user prepares for bedtime, for example, in connection with activation of each mode in the mode setting process.
The wake-up switch 123 is, for example, a switch that is operated when the user wakes up in the preset process.

The selection switch 124 selects, for example, a situation designation means for a situation performed by the user before going to bed (for example, 30 minutes to 1 hour before going to bed) in the before-sleep situation menu g1 (see FIG. 12A). This is a switch for (designation).
The selection switch 124 is a switch for instructing the user to select a situation at the time of wakeup in the wakeup situation menu g2 (see FIG. 12B).

  The determination switch 125 is, for example, a switch for determining a selection instruction for each item selected by the selection switch 124.

The sleep sensor 17 of the present embodiment detects a pulse rate (biological information) in the capillary artery B for detection of the user's sleep state.
It is known that the pulse rate of the body and the sleep state (shallow and deep) correlate, and the pulse rate decreases when the sleep state of the body is deep, and the pulse rate increases when the sleep state is shallow. Therefore, the sleep sensor 17 of the present embodiment is configured to detect the pulse rate (biological information) in the capillary artery B in order to detect the user's sleep state using this principle.
Specifically, for example, as shown in FIGS. 4 and 5, the sleep sensor 17 is provided on a back cover 18 (contact portion) that contacts the user's arm A, and includes a light emitting element 171 and a light receiving element 172. And a pulse rate detector 173 and the like.

Among these, the back cover 18 includes, for example, a transparent glass 181 that transmits light of a predetermined wavelength related to detection of a pulse at the center thereof.
Further, on the surface on the arm A side of the back cover 18, annular external light intrusion prevention portions 182 are provided at both end portions in the direction along the arm periphery direction (for example, both left and right end portions in FIG. 4). The external light intrusion prevention unit 182 is formed in a shape that protrudes toward the arm A side, and is outside that interferes with detection of light (details will be described later) emitted from the light emitting element 171 and reflected by the capillary artery B of the arm A. It works to prevent light from entering.
Further, at both ends of the back cover 18 on the arm A side and in the direction orthogonal to the direction around the arm, the shape memory property is low, for example, in the same manner as the mounting portion side arm contact portion 21. A main body side arm contact portion 183 that is made of a repulsive material (for example, low-resilience urethane) and deforms according to the shape of the surface of the arm A is provided. Thereby, the adhesiveness with respect to the arm A of the wristwatch 100 with a sleep sensor can be improved (refer FIG. 2).

For example, the light emitting element 171 emits light having a predetermined wavelength toward the arm A through the transparent glass 181 of the back cover 18.
For example, the light receiving element 172 is not absorbed by hemoglobin in blood flowing through the capillary artery B passing through the inside of the arm A out of the light emitted from the light emitting element 171 to a predetermined portion of the arm A. Light reflected and scattered is received through the transparent glass 181.
The pulse rate detection unit 173 detects the pulse rate based on a change in the amount of light received by the light receiving element 172, for example. That is, since the amount of hemoglobin flowing through the capillary artery B changes in a wave manner due to blood pulsation, the light absorbed in the hemoglobin also changes in a wave manner. Therefore, based on such a principle, the pulse rate detection unit 173 of the embodiment acquires pulse wave information based on a change in the amount of received light that is reflected by the capillary artery B and detected by the light receiving element 172, and the pulse wave information is obtained. The pulse interval is detected from the wave to detect the pulse rate. The pulse rate detection unit 173 outputs a signal related to the detected pulse rate to the CPU 161.

The notification unit 19 notifies, for example, that the user is getting up with an alarm sound under the control of the CPU 161, and constitutes a notification control unit as in the case of the display unit 14.
For example, the notification unit 19 may notify that it is a wake-up time by generating a vibration or a scent instead of the alarm sound.

  For example, a CPU (Central Processing Unit) 161, a ROM (Read Only Memory) 162, a RAM (Random Access Memory) 163, and the like are mounted on the printed circuit board 16.

  The CPU 161 reads various programs stored in the ROM 162 based on, for example, a predetermined timing or an operation signal input from the key switch unit 12 and expands the programs in the work area of the RAM 163, and performs various processes according to the programs. Is to execute. Specifically, for example, the CPU 161 performs various controls such as outputting a predetermined display signal to the display unit 14 to display the current time based on the current time data timed by the time measuring unit 151. ing.

  The ROM 162 is a read-only memory. For example, the sleep time acquisition program 162a, the predicted wakeup calculation program 162b, the sleep state detection program 162c, the first sleep state determination program 162d, the wakeup prediction time specifying program 162e, the second A sleep state determination program 162f, a first notification control program 162g, a second notification control program 162h, and the like are stored.

Among these, the sleep time acquisition program 162a causes the CPU 161 to function as a sleep time acquisition means. That is, the sleep time acquisition program 162a causes the CPU 161 to realize a function related to the sleep time acquisition process for acquiring the sleep time from the start of going to sleep until falling asleep based on the pulse rate detected by the sleep sensor 17. It is a program. Specifically, the sleep time acquisition program 162a uses the CPU 161 to identify the time of sleep after sleep from the change in the pulse rate detected by the sleep sensor 17, and calculates the sleep time from the sleep time and the sleep time. Is to do.
Here, the determination of falling asleep is, for example, when the average value of 3 minutes of the pulse rate after going to bed is reduced by 5% or more than the basic value of the awake state for 4 minutes or when the pulse rate after going to bed is 3 This is performed by setting the sleep time when the average value of the minute is decreased by 7% or more from the basic value, or when the increment is less than 3 and the variation is less than 7. Of course, it is not limited to this.

The predicted wakeup calculation program 162b causes the CPU 161 to function as a predicted wakeup calculation unit. That is, when the sleep expectation time calculation program 162b stores sleep time information in the RAM 163 in advance and designates the desired sleep time based on a predetermined operation of the key switch unit 12 by the user, the sleep desired time and the RAM 163 are specified. Is a program for causing the CPU 161 to realize a function related to a predicted wake-up time calculation process for calculating a predicted wake-up time and a predicted wake-up time based on the sleep time stored in the computer. Specifically, the expected wake-up time calculation program 162b calculates, in the first measurement mode (described later), an average value of a plurality of sleep times corresponding to the situation before going to bed by the CPU 161, and designates the average value as the average value. To calculate the expected wake-up time after a predetermined time has elapsed from the current time by adding the desired sleep time, or to calculate the expected wake-up time by adding the current time to the expected wake-up time .
For the calculation of the expected wake-up time and the expected wake-up time, for example, the sleep time set in the latest preset process or the sleep time arbitrarily selected by the user is used instead of the average value of the sleep time. May be.

The sleep state detection program 162c is based on the pulse rate detected by the sleep sensor 17 after the designation of the state before going to bed by a predetermined operation of the key switch unit 12 by the user, until the body wakes up from the sleep state to the awake state. It is a program for making CPU161 implement | achieve the function which concerns on the sleep state detection process which detects this sleep state. Specifically, whether the sleep state detection program 162c is a sleep state of the user's body, that is, a deep sleep state (non-REM sleep) from a change in pulse rate detected by the sleep sensor 17 during sleep by the CPU 161. This is for detecting whether the sleep state is shallow (REM sleep) or whether the sleep state is changed to the awake state. And the time when it became a deep sleep state, a shallow sleep state, and the time when it became an awake state (wake-up time) are acquired from the time measuring part 151 under control of CPU161, and are memorize | stored in RAM163 as sleep state information 163b. It is like that.
Therefore, the CPU 161 constitutes a wake-up time detecting means for detecting the wake-up time when the body has changed from the sleep state to the awake state in cooperation with the sleep sensor 17 and the clock unit 151 by executing the sleep state detection program 162c. is doing.

  The first sleep state determination program 162d is for causing the CPU 161 to function as a sleep state determination unit. That is, the first sleep state determination program 162d is based on the estimated wake-up time and the estimated wake-up time calculated in the wake-up predicted time calculation process based on the pulse rate detected by the sleep sensor 17 after going to bed. It is a program for making CPU161 implement | achieve the function which concerns on the 1st sleep state determination process which determines whether the body is in a shallow sleep state at the time of. Specifically, the first sleep state determination program 162d wakes up the time measured by the timer unit 151 from the change in the pulse rate detected by the sleep sensor 17 by the CPU 161 in the first measurement mode. Continuous at a certain time (for example, 3 minutes) after the pulse rate increases and reaches a peak at the time when the expected time arrives or when the estimated time of wake-up has passed, for example, until the expected wake-up time or the expected wake-up time Thus, it is for determining whether or not the body is in a shallow sleep state according to whether or not the number of the sleeps has decreased (for example, this corresponds to the case where the desired sleep time 1 in FIG. 16 is designated).

Here, the determination of whether the body is in a shallow sleep state at the time when the expected wake-up time arrives and when the expected wake-up time elapses may be given priority, for example, at a time when the awakening is clear. It is also possible to prioritize the wake-up time (time).
That is, for example, if the time when the sleep state is shallow is about 10 minutes even after the expected wake-up time arrives or after the expected wake-up time has elapsed, priority is given to clear awakening and the expected wake-up time It may be determined that the body has entered a shallow sleep state after arrival or after the expected wake-up time. Thus, in the subsequent second notification control process (described later), the alarm can be notified at the time when the body is in a shallow sleep state (for example, the desired sleep time 2 in FIG. 16 is designated). Corresponding to the case).
On the other hand, if priority is given to the wake-up time, if the user wakes up significantly beyond the time desired by the user, the alarm will become unusable, and more than 10 minutes have passed since the expected wake-up time or the expected wake-up time has elapsed. If it is later determined that the body is in a shallow sleep state, it may be determined that the body has entered a shallow sleep state at the time when the shallow sleep state is one prior to the shallow sleep state (for example, This corresponds to the case where the desired sleep time 3 in FIG. 16 is designated).
In addition, based on half (for example, 45 minutes) of a sleep cycle (for example, about 90 minutes) from non-REM sleep to non-REM sleep, for example, 45 minutes, the time when the body enters a shallow sleep state is the previous shallow sleep. You may make it determine whether it is set as a state.

  The predicted wakeup specifying program 162e is for causing the CPU 161 to function as a predicted wakeup specifying means in the second measurement mode (described later). That is, the anticipated wake-up time specifying program 162e stores the sleep state information 163b in the RAM 163 by associating the state before going to sleep with the body wake-up time, and then sleeping based on a predetermined operation of the key switch unit 12 by the user. When the previous situation is designated, a program for causing the CPU 161 to realize a function related to the anticipated wake-up time specifying process for specifying the wake-up time of the body stored in the RAM 163 in association with the pre-sleeping situation as the expected wake-up time It is.

The second sleep state determination program 162f is for causing the CPU 161 to function as a sleep state determination unit. In other words, the second sleep state determination program 162f is shallow at a time point near the time when the expected wake-up time specified by the wake-up predicted time specifying process is based on the pulse rate detected by the sleep sensor 17 after going to bed. It is a program for causing the CPU 161 to realize a function related to the second sleep state determination process for determining whether or not the patient is in a sleep state. Specifically, in the second measurement mode, the second sleep state determination program 162f is obtained from the change in the pulse rate detected by the sleep sensor 17 by the CPU 161 in substantially the same manner as the first sleep state determination process. The time measured by the time measuring unit 151 is close to the time when the expected wake-up time arrives, for example, it is determined whether the body is in a shallow sleep state within an allowable range as an alarm of about 10 minutes before and after the expected wake-up time. Is for.
Here, the allowable range near the expected wake-up time is set to be within 10 minutes before and after the predicted wake-up time, but is not limited thereto.

  The first notification control program 162g is for causing the CPU 161 to function as notification control means. In other words, the first notification control program 162g notifies the notification unit 19 of the predicted wake-up time and the predicted wake-up time calculated by the expected wake-up time calculation process and the predicted wake-up time specified by the wake-up expected time specification process. This is a program for causing the CPU 161 to realize the function related to the notification control process. Specifically, the first notification control program 162g causes the display unit 14 to display the expected wake-up time and the expected wake-up time before going to bed by the CPU 161 in the first measurement mode and the second measurement mode. Is.

  The second notification control program 162h is for causing the CPU 161 to function as notification control means. That is, when the second notification control program 162h determines that the body is in a shallow sleep state by the first sleep state determination process or the second sleep state determination process, the notification unit 19 indicates that it is a wake-up time. It is a program for making CPU161 implement | achieve the function which concerns on the 2nd alerting | reporting control process notified from. Specifically, the second notification control program 162h is sleeping in the first measurement mode or the second measurement mode by the CPU 161 at the time when the expected wake-up time arrives or when the expected wake-up time has elapsed. When the body is in a shallow sleep state, the alarm unit 19 notifies the user that the user is getting up by an alarm.

  In addition, the ROM 162 stores screen information such as a pre-sleep situation menu g1, a wake-up situation menu g2, a desired sleep time selection screen g3, and a predicted wake-up screen g4.

The screen information of the bedtime status menu g1 includes, for example, a predetermined column number (“1” to “10”), “food”, “exercise (fitness)”, “exercise (yoga)”, “drinking”, “ The contents such as “study” and “taste incense” are associated (see FIG. 6).
The screen information of the wake-up state menu g2 includes, for example, a predetermined column number (“1” to “10”) and “very clean”, “easy”, “hangover”, “very awake”, etc. Are associated with each other (see FIG. 7).
The screen information of the desired sleep time selection screen g3 includes, for example, a predetermined column number (“1” to “10”), “30 minutes”, “45 minutes”, “60 minutes (1 hour)”, “75 minutes”. "," 90 minutes (one and a half hours) "," N minutes (M hours) ", and the like are associated (see FIG. 15B).
The screen information on the predicted wake-up screen g4 relates to, for example, predicted wake-up time, predicted wake-up time, wake-up state prediction comment, and the like (see FIGS. 15C and 18B).

  The RAM 163 is, for example, a volatile semiconductor memory, and constitutes a storage area, a work area, and the like for programs and data read from the ROM 162 under the control of the CPU 161.

The RAM 163 functions as a sleep time storage unit. This RAM 163 is acquired by a sleep time acquisition process before (in advance) the alarm process by the CPU 161 in the first measurement mode and the second measurement mode, for example. The time information 163a (see FIG. 8) is stored.
Here, the “sleeping time information 163a” is, for example, information in which a sleeping time, a sleeping time, and a sleeping time are associated with each other for each sleeping date, as illustrated in FIG.

Further, the RAM 163 is detected by the user's sleep state specified based on a predetermined operation of the key switch unit 12 and the sleep state detection process before the alarm processing by the CPU 161, and the sleep state of the body or The sleep state information 163b (see FIG. 9) associated with information such as the wake-up time when the sleep state is changed to the awake state is stored.
Here, “sleep state information 163b” means, for example, as shown in FIG. 9, for each date of going to bed, the state before bedtime, bedtime, sleep time, sleep state (deep sleep state or shallow sleep state), It is information in which the wake-up time and the situation (evaluation) at the time of wake-up are associated with each other.
Accordingly, the RAM 163 constitutes a wake-up time storage unit that stores in advance the state before going to bed and the wake-up time when the body changes from the sleep state to the awake state.

Next, a method for using the wristwatch with sleep sensor 100 of the present embodiment and an operation process during use will be described with reference to FIGS.
Here, FIG. 10 is a flowchart showing an example of an operation related to the mode setting process.

When using the sleep sensor-equipped wristwatch 100 of the present embodiment as an alarm (alarm clock), first, a sleep state corresponding to a user's sleep time within a predetermined period (for example, one month) or a situation before going to bed, etc. Is measured and stored in advance in sleep time information 163a and sleep state information 163b of RAM 163 (preliminary setting), and alarm processing is performed using these information.
Specifically, in the wristwatch 100 with a sleep sensor, as shown in FIG. 10, in the mode setting process, the CPU 161 executes the pre-setting process based on a predetermined operation of the key switch unit 12 by the user. It is determined whether execution of any one of the preset mode, the first measurement mode related to the execution of the first alarm process, or the second measurement mode related to the execution of the second alarm process is instructed ( Step S1).
In step S1, if the CPU 161 determines that execution of the preset mode is instructed, the process proceeds to step S2 to control execution of the preset process, and execution of the first measurement mode is instructed. If it is determined that the execution of the first alarm process is controlled, the process proceeds to step S3. If it is determined that the execution of the second measurement mode is instructed, the process proceeds to step S4 and the second alarm process is performed. Control the execution of
Hereinafter, (1) pre-setting processing in the pre-setting mode, (2) execution of the first alarm processing in the first measurement mode, and (3) execution of the second alarm processing in the second measurement mode will be described in this order. To do.

First, the pre-setting process in the pre-setting mode will be described with reference to FIGS.
FIG. 11 is a flowchart illustrating an example of an operation related to the pre-setting process. FIG. 12 is a diagram showing a display screen displayed on the sleep sensor-equipped wristwatch 100 in the pre-setting process. Of these, FIG. 12A shows the pre-sleep situation menu g1, and FIG. 12B shows the display screen. Each of the wake-up situation menus g2 is shown. FIG. 13 is a diagram schematically showing the temporal transition of the pulse rate in the presetting process.

In the presetting process, first, the CPU 161 determines whether or not the user has pressed the sleep switch 122 before going to bed (step S201).
If it is determined that the sleep switch 122 is pressed (step S201; YES), the CPU 161 reads out the image information of the pre-sleep condition menu g1 (see FIG. 12A) from the ROM 162, and displays it. 14 (step S202). Then, in the state where the pre-sleep situation menu g1 is displayed, the CPU 161 selects and determines the type of action (eg, “drinking”) performed before going to bed when the selection switch 124 is pressed by the user. If it is determined that the determination switch 125 for pressing has been pressed (step S203; YES), the sleep sensor 17 is controlled to start detection of the pulse rate, and the column number corresponding to the selected state before going to bed (for example, , “4” corresponding to “drinking” is stored as sleep state information 163b in the RAM 163 as a bedtime state and the time when the decision switch 125 is operated as a bedtime (step S204).

Thereafter, based on the execution of the sleep time acquisition program 162a, the CPU 161 determines whether the body has transitioned from the awake state to the sleep state and has fallen asleep based on the change in the pulse rate detected by the sleep sensor 17. (Step S205; see FIG. 13).
When it is determined that the user has fallen asleep (step S205; YES), the CPU 161 sets the time counted by the time measuring unit 151 as the sleep time, and stores the sleep time in the RAM 163 as the sleep state information 163b. The sleep time is calculated from the sleep time and the sleep time, and the sleep time is stored in the RAM 163 as the sleep time information 163a. The sleep state detection program 162c is executed to detect the sleep state in real time, and the sleep state is stored in the RAM 163. The information is stored as information 163b (step S206).

Thereafter, based on the change in the pulse rate detected by the sleep sensor 17, the CPU 161 determines whether the body has transitioned from the sleep state to the awake state and has woken up, or whether the user has pressed the wake-up switch 123. It is determined whether or not (step S207; see FIG. 13).
If it is determined that the user has woken up or the wake-up switch 123 has been operated (step S207; YES), the CPU 161 sets the time counted by the time measuring unit 151 as the wake-up time and stores the wake-up time in the RAM 163. While being stored as the sleep state information 163b, the image information of the wake-up state menu g2 (see FIG. 12B) is read from the ROM 162 and displayed on the display unit 14 (step S208). Then, in the state where the wake-up state menu is displayed, the CPU 161 presses the selection switch 124 by the user to select the type of the state at the time of wake-up, and the determination switch 125 for determining it is pressed. If it is determined that the user is present (step S209; YES), the wake-up state is stored in the RAM 163 as sleep state information 163b (step S210).
Thereby, the pre-setting process ends.

Next, alarm processing in the first measurement mode (hereinafter referred to as “first alarm processing”) will be described with reference to FIGS.
FIG. 14 is a flowchart illustrating an example of an operation related to the first alarm process. FIG. 15 is a view showing a display screen displayed on the sleep sensor-equipped wristwatch 100 in the first alarm process. FIG. 15A shows a pre-sleep situation menu g1 and FIG. ) Shows the desired sleep time selection screen g3, and FIG. 15C shows the first expected wake-up time screen g41. FIG. 16 is a diagram schematically showing the temporal transition of the pulse rate in the first alarm process.

In the first alarm process, first, the CPU 161 determines whether or not the user has pressed the sleep switch 122 before going to bed (step S301).
Here, if it is determined that the sleep switch 122 is pressed (step S301; YES), the CPU 161 determines the pre-sleep situation menu g1 (see FIG. 15A) and sleep based on the image information read from the ROM 162. A desired time selection screen g3 (see FIG. 15B) is displayed on the display unit 14 (step S302). Then, in a state where the pre-sleep state menu g1 and the desired sleep time selection screen g3 are displayed, the CPU 161 selects the type of action performed before going to bed (for example, “study”) by pressing the selection switch 124 by the user. When the desired sleep time (for example, “60 minutes (1 hour)”) is selected and it is determined that the determination switch 125 for determining them is pressed (step S303; YES), the sleep sensor 17 is controlled. While detecting the pulse rate, the column number corresponding to the selected pre-sleep situation (for example, “5” corresponding to “study”) and the column number corresponding to the selected desired sleep time (for example, “ "3" corresponding to "60 minutes (1 hour)" and the time when the decision switch 125 is operated are acquired as the bedtime and stored in the RAM 163 ( Step S304).

  After that, the CPU 161 reads a plurality of sleep times corresponding to the state before going to bed from the sleep state information 163b of the RAM 163 based on the execution of the predicted rising time calculation program 162b, and then averages these values (for example, “ 30 minutes "), and an expected wake-up time (e.g.," 90 minutes ") and expected wake-up time (e.g.," 23:00 ") are calculated from the average value and the designated desired sleep time (step S305). ). Then, the CPU 161 executes the first notification control program 162g to display the expected wake-up time and the expected wake-up time (see FIG. 15C) on the display unit 14 before going to bed, and the sleep state detection program 162c. The sleep state is detected in real time and stored in the RAM 163 (step S306).

Thereafter, based on the execution of the first sleep state determination program 162d, the CPU 161 shifts from the awake state to the sleep state based on the change in the pulse rate detected by the sleep sensor 17, and the expected arrival time of arrival is reached. It is determined whether or not the body is in a shallow sleep state at a time near the time when the predicted wake-up time or the estimated wake-up time has elapsed and when the predicted wake-up time has arrived or the estimated wake-up time has elapsed (step S307; FIG. 16).
Here, if it is determined that the body is in a shallow sleep state (step S307; YES), the CPU 161 executes the second notification control program 162h, and an alarm is given from the notification unit 19 that it is the time of waking up. (Step S308).
Thus, the first alarm process is finished.

Next, alarm processing in the second measurement mode (hereinafter referred to as “second alarm processing”) will be described with reference to FIGS.
FIG. 17 is a flowchart illustrating an example of an operation related to the second alarm process. FIG. 18 is a diagram showing a display screen displayed on the wristwatch 100 with a sleep sensor in the second alarm processing. Of these, FIG. 18A shows the pre-sleep situation menu g1 and FIG. ) Represents the second expected wakeup screen g42. FIG. 19 is a diagram schematically showing the temporal transition of the pulse rate in the second alarm processing.

In the second alarm process, first, the CPU 161 determines whether or not the user has pressed the sleep switch 122 before going to bed (step S401).
Here, if it is determined that the sleep switch 122 is pressed (step S401; YES), the CPU 161 reads out the image information of the pre-sleep condition menu g1 (see FIG. 18A) from the ROM 162 and displays it. 14 (step S402). In the state where the pre-sleep situation menu g1 is displayed, the CPU 161 selects the action type (eg, “study”) performed before going to bed by pressing the selection switch 124 by the user and determines it. When it is determined that the determination switch 125 for pressing is pressed (step S403; YES), the time when the determination switch 125 is operated is acquired as the bedtime and stored in the RAM 163 (step S404).

Subsequently, the CPU 161 stores the sleeping time (hereinafter referred to as “equivalent sleeping time”) corresponding to the acquired sleeping time (hereinafter referred to as “acquired sleeping time”) in the sleep state information 163b of the RAM 163. That is, it is determined whether or not the equivalent bedtime stored in the preset process is stored in the sleep state information 163b near the acquired bedtime (for example, within about 10 minutes before and after) (step S405). .
Here, if it is determined that the corresponding bedtime is stored in the sleep state information 163b (step S405; YES), the CPU 161 controls the sleep sensor 17 to start detecting the pulse rate and at the time of expected wake-up. The identification program 162e is executed, and the wake-up time and the wake-up state corresponding to the selection-instructed state before going to bed are acquired and specified from the sleep state information 163b of the RAM 163, and the wake-up time is determined as the expected wake-up time (for example, “7 0:00 ”), and the wake-up state is displayed on the display unit 14 as a wake-up state predicted comment (for example, wakes up in a“ easy ”state) (step S406).

Thereafter, based on the execution of the sleep time acquisition program 162a, the CPU 161 determines whether the body has transitioned from the awake state to the sleep state and has fallen asleep based on the change in the pulse rate detected by the sleep sensor 17 ( Step S407; see FIG.
If it is determined that the user has fallen asleep (step S407; YES), the CPU 161 executes the sleep state detection program 162c to detect the sleep state in real time and store it in the RAM 163 (step S408).

Thereafter, based on the execution of the second sleep state determination program 162f, the CPU 161 shifts from the awake state to the sleep state based on the change in the pulse rate detected by the sleep sensor 17, and is close to the expected wake-up time. It is determined whether or not the body is in a light sleep state by the predicted wake-up time (step S409; see FIG. 19).
Here, if it is determined that the body is in a shallow sleep state (step S409; YES), the CPU 161 determines from the notification unit 19 that it is a wake-up time based on the execution of the second notification control program 162h. An alarm is notified (step S410).

  If it is determined in step S405 that the bedtime is not stored as sleep state information 163b in the RAM 163 (step S405; NO), the second alarm process is terminated.

As described above, according to the wristwatch 100 with the sleep sensor of the present embodiment, in the first alarm process, the sleep time information 163a related to the sleep time from the start of going to bed until falling asleep is stored in advance. When the desired sleep time is specified based on a predetermined operation of the key switch unit 12 by the user, the expected wake-up time and the expected wake-up time are calculated based on the desired sleep time and the sleep time stored in advance. be able to. That is, the expected wake-up time and the expected wake-up time can be calculated based on the sleep time in consideration of individual differences among users.
And when the body is in a shallow sleep state at the time when the expected wake-up time arrives or when the expected wake-up time elapses, it can be notified from the notification unit 19 by an alarm that the user is in the sleep state. It is possible to notify the optimal wake-up time for the user, and thereby to wake up the user with a clear awakening.
Further, in the second alarm processing, after the wake-up time when the body has changed from the sleeping state to the awake state is stored in advance as the sleeping state information 163b in association with the state before the body goes to sleep, the key switch by the user When the state before going to bed is specified based on the predetermined operation of the unit 12, the wake-up time stored in association with the state before going to bed can be specified as the expected wake-up time. That is, it is possible to specify the expected wake-up time in consideration of the situation before the user goes to bed.
And when the body is in a shallow sleep state near the time when the expected wake-up time arrives, it is possible to notify the wake-up time from the notification unit 19 by an alarm, so the optimal wake-up time for the user can be determined. The user can be notified, and thereby the user can be woken up with a clean awakening.

  In addition, by notifying the display unit 14 of the expected wake-up time and the expected wake-up time before going to bed, the user can recognize the expected wake-up time and the expected wake-up time before going to bed, and thus a more convenient sleep sensor. The wristwatch 100 can be provided.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, in the above embodiment, as a method for specifying the desired sleep time, a desired sleep time is selected based on a predetermined operation of the selection switch 124 from a plurality of times displayed on the desired sleep time selection screen g3 (see FIG. 15B). Although the configuration is such that the desired sleep time is selected, the present invention is not limited to this, and the desired sleep desired time may be directly specified by a numerical value on the sleep desired time selection screen g3.

Further, in the above-described embodiment, both the expected wake-up time and the expected wake-up time are calculated in the expected wake-up time calculation process, but the present invention is not limited to this. What is necessary is just to calculate at least one.
Furthermore, in the above embodiment, only the predicted wake-up time is specified in the expected wake-up time specifying process, but this is not a limitation, and at least one of the expected wake-up time and the expected wake-up time can be calculated. It ’s fine. That is, the CPU 161 may calculate and specify the expected wake-up time based on the wake-up time and the current time of the sleep state information 163b.

Furthermore, the sleep sensor 17 is not restricted to what was illustrated to the said embodiment. That is, since the blood flow is also affected by body movements, the pulse rate detected by the pulse rate detection unit 173 of the sleep sensor 17 according to the above embodiment is synchronized with not only the pulse component synchronized with the pulse but also the body movement. May also be included. Further, not all of the irradiated light reaches the capillary artery B, and reflected light (surface reflected light) reflected by the surface of the arm A (body) is also received by the light receiving element 172, and the body is also reflected in the surface reflected light. It contains a lot of dynamic components.
Therefore, instead of the sleep sensor 17 in the above embodiment, a sleep sensor that considers a body motion component may be provided. That is, the sleep sensor is equipped with, for example, light emitting elements that irradiate infrared light and green light having different light absorption characteristics, and pulse wave information consisting of a pulse component and a body motion component is detected by causing the green light emitting element to emit light. By detecting the pulse rate based on the pulse wave information and the body motion information, the infrared light emitting element emits light to detect the body motion information mainly including the body motion component compared to the pulse component. Also good.
In addition, the body movement information may be used for the determination of falling asleep. Specifically, for example, the body movement is not continuous for a predetermined time (for example, 5 minutes) and the pulse rate is the basic value of the awake state. Alternatively, the time point when the number of beats has decreased by a predetermined number of beats (for example, 5 beats) or more may be determined as the sleep time.

  Moreover, the determination method of a sleep state is not restricted to what was illustrated to the said embodiment, For example, based on the magnitude | size of the frequency component acquired by frequency-analyzing a pulse interval, REM sleep and non-REM sleep are carried out. You may make it detect.

  Furthermore, when the user wakes up in the middle of the sleep in the pre-setting process in the above embodiment, the progress of the time and behavior may be stored as the sleep state information 163b. It is possible to provide a wristwatch with an easy-to-use sleep sensor that takes rhythm into consideration.

Moreover, in the said embodiment, the condition before sleep is designated, the sleep time corresponding to the condition before the sleep is acquired from the sleep time information 163a, and the expected wake-up time and the like are calculated based on the acquired sleep time. Although it did it (refer FIG.14 and FIG.15), it can change suitably whether the condition before going to bed is designated. In other words, in the preset mode, after sleeping without specifying the condition before going to bed, the calculated sleeping time is stored in the sleeping time information 163a, and the sleeping time not considering the situation before going to bed is used. An estimated wake-up time or the like may be calculated.
Even in such a configuration, it is possible to calculate the expected wake-up time and the expected wake-up time based on the sleep time in consideration of individual differences among users, and the predicted wake-up time and the expected wake-up time are optimal for the user. It can be notified as the wake-up time, and thus the user can be woken up with a clear awakening.

  Further, in the above embodiment, the first sleep state determination process or the second sleep state determination process is a sleep state in which the body is in a shallow sleep state when reaching the expected wake-up time or when the expected wake-up time has elapsed. However, the present invention is not limited to this, for example, without performing the first sleep state determination process or the second sleep state determination process, When the estimated wake-up time calculated in the first alarm process and the estimated wake-up time have elapsed, or when the estimated wake-up time specified in the second alarm process has arrived, an alarm will inform you that it is time to wake up. May be. Accordingly, the user can recognize that the user is getting up, and can provide the sleep sensor-equipped wristwatch 100 that is more convenient to use.

  In addition, in the said embodiment, although the wristwatch 100 with a sleep sensor was illustrated as a body mounting apparatus with a sleep sensor, it is not restricted to this, Each part (for example, a limb, an ankle, etc.) is provided with the sleep sensor 17. Any device can be used as long as it can be attached to the electronic device), for example, an electronic compass or a chest belt type pulse meter.

  Moreover, in the said embodiment, although a user's pulse rate was used for the detection of a sleep state etc., it is not restricted to a pulse rate, You may use a pulse volume fluctuation | variation state, a pulse peak value fluctuation | variation state, etc. Further, the biological information is not limited to the pulse, and other biological information such as weak electricity generated in the muscle, so-called myoelectricity or heartbeat may be used, for example.

  Furthermore, in the above embodiment, the CPU 161 functions as a predetermined program or the like as a sleep time acquisition unit, a predicted rising time calculation unit, a notification control unit, a sleep state determination unit, a sleep state detection unit, and a predicted rising time specification unit. However, the present invention is not limited to this. For example, a logic circuit for realizing various functions may be used.

  The body wearing device with a sleep sensor according to the present invention may incorporate a function of notifying the sleeping state. In this case, the user can easily and properly detect the sleeping state of the body while wearing the body. Thus, by notifying the user or the like that the sleep state has been reached, it is possible to prevent a doze while driving a car and contribute to the realization of safe driving.
