Hereinafter, an embodiment of a control method that may be implemented in the mobile terminal 100 configured as described above will be described with reference to FIGS. 4 to 5B.

For convenience of description, it is assumed that the mobile terminal 100 mentioned below includes at least some of the components shown in FIGS. 1 to 3. Specifically, the mobile terminal 100 according to the present invention includes a housing 101, a battery 191, a motion detection unit 142, an alarm unit 153, and a control unit among the components illustrated in FIGS. 1 to 3. 180).

As described above, the housing 101 constitutes an exterior of the mobile terminal 100 and includes various electronic components, various modules, and a battery 191. Electronic components provided in the housing 101 may constitute the motion detector 142, the alarm 153, and the controller 180. The motion detector 142 detects the movement of the housing 101 when activated, and the alarm unit 153 outputs an alarm. The battery 191 supplies power to the motion detector 142 and the alarm unit 153.

The controller 180 may change the alarm output time different from the preset reference alarm time based on the movement of the housing 101 collected by the motion detector 142. The changed alarm output time is preferably when the user can wake up more effectively. According to an embodiment of the present disclosure, the user may be sleeping at the first sleep stage at the changed alarm output time, and the first sleep stage may occur within a predetermined time before and after the preset reference alarm time. For example, when the first sleep step occurs within 30 minutes before and after the reference alarm time, the controller 180 may control the alarm unit 153 to output an alarm when the first sleep step occurs.

The sleep stage in which the user configures sleep may be determined based on the movement of the housing 101 sensed by the motion detector 142. The sleep stage may be divided into first to fourth sleep stages and a REM sleep stage.

The first stage of sleep is an intermediate stage between arousal and sleep, usually with low and fast brain waves and the relaxation of muscle activity. In the second sleep stage, the breathing, pulse and brain waves gradually become slower, and in the third sleep stage, the deep sleep starts, and the brain waves move very slowly. In the fourth stage of sleep, they fall into deep sleep, which no longer responds to external stimuli but only a limited muscle response. During the REM sleep phase, the brain waves, breathing increases, and the eye moves quickly despite deep sleep. Therefore, unlike in the second to fourth sleep stages and the REM sleep stages, which are relatively deep sleep stages, the first sleep stage can effectively wake up a person by an external stimulus.

Preferably, the greater the movement of the housing 101 and the higher the frequency of the movement, the closer to the first sleep stage, and the closer to the fourth sleep stage, the less the movement of the housing 101. A criterion for determining each sleep stage may be preset, and the criterion may include the magnitude of the movement of the housing 101 or the frequency per hour of the movement of the housing 101.

In this embodiment, the motion detector 142 detects the movement of the housing 101 only when it is activated. At this time, the controller 180 controls whether the motion detection unit 142 is activated according to the remaining power of the battery 191, and the motion detection unit 142 according to the remaining power of the battery 191 at different time intervals ( I, see FIG. 5A). That is, the controller 180 controls the motion detector 142 so that the motion detector 142 can detect the movement of the housing 101 at different time intervals according to the remaining power of the battery 191.

Preferably, the time interval I may be shorter as the remaining amount of power of the battery 191 is increased and longer as the remaining amount of power of the battery 191 is short. For example, when the remaining amount of power of the battery 191 is 80%, the controller 180 activates the motion detection unit 142 at an interval of 1 hour, and when the remaining amount of power of the battery 191 is 30%, the motion detecting unit 142. ) Can be activated every hour and a half.

According to one embodiment, the length of time (d, see FIG. 5A) during which the motion detector 142 continues the motion detection of the housing 101 may also be changed according to the remaining power of the battery 191. To this end, the controller 180 may control whether the motion detector 142 is activated so that the motion detector 142 detects the movement of the housing 101 for a different time depending on the remaining power of the battery 191. .

Preferably, the activation duration length d of the motion detector 142 may be longer as the remaining power of the battery 191 increases, and shorter as the remaining power of the battery 191 decreases. For example, when the remaining amount of power of the battery 191 is 80%, the controller 180 may maintain the activation state for 30 minutes when the motion detection unit 142 is activated once, and the remaining amount of power of the battery 191 is 30%. If so, you can keep it for 15 minutes.

Detailed control flow of the mobile terminal 100 related to the above embodiment is as shown in Figs. 4 is a control flowchart of the mobile terminal 100 according to the present embodiment, and FIGS. 5A and 5B are examples of use of an alarm of the mobile terminal 100 according to FIG. 4 when the remaining battery power is 80% and 30%, respectively. Is shown as a graph of sleep time.

 First, as shown in FIG. 4, the controller 180 checks the power remaining amount of the battery 191 (S410). After checking the remaining power of the battery 191, the controller 180 activates the motion detection unit 142 at a time interval corresponding to the confirmed remaining power of the battery 191 (S420). A time interval corresponding to the remaining amount of power of each battery 191 may be preset, and may be continuously changed or stepped with respect to the remaining amount of power of the battery 191. For example, when the remaining power of the battery 191 is 80%, the corresponding time interval may be 1 hour.

The motion detector 142 activated at predetermined time intervals as described above detects the movement of the housing 101 (S430). According to an embodiment, the motion detector 142 may include a gyro sensor. In this case, the motion detection unit 142 may detect the acceleration when the housing 101 moves, and the motion detection unit 142 when the housing 101 of the mobile terminal 100 is placed together on the mattress while the user is sleeping. Can detect the movement of the mattress. The motion detector 142 may indirectly detect the movement of the sleeping user by detecting the movement of the mattress. The mobile terminal 100 of the present invention may be worn on the arm of a sleeping user. In this case, the gyro sensor may directly detect the movement of the sleeping user.

When the motion detector 142 detects the movement of the housing 101, the controller 180 may determine a sleep stage based on the detected movement of the housing 101 (S440). The motion detector 142 may detect the movement of the user who is sleeping while the housing 101 moves, and the sleep stage may be determined based on the detected movement of the user's sleep. As described above, the criteria for determining each sleep stage may be the frequency per hour of housing 101 movement or the magnitude of the housing 101 movement. The magnitude of the movement of the housing 101 may be proportional to the magnitude of the acceleration measured by the gyro sensor when the motion detector 142 includes the gyro sensor.

For example, the change in the sleep stage according to the sleep time may be represented as shown in FIG. 5A. When the remaining amount of the battery 191 is 80%, the activation time interval I of the motion detector 142 may be 1 hour, and the activation duration length d may be 30 minutes. In this case, as shown in FIG. 5A, the motion detector 142 may be activated every 1 hour after the user sleeps to detect movement of the housing 101, that is, movement of the user's sleep for 30 minutes. The movement of the housing 101 may be sensed for a time from when the user sleeps until the alarm is output.

As another example, as shown in FIG. 5B, when the remaining battery 191 is 30%, the activation time interval I of the motion detector 142 may be 1 hour 30 minutes, and the activation duration length d may be It can be 15 minutes.

Referring back to FIG. 4, the controller 180 can determine whether the determined sleep step is a first sleep step (S442). If the sleep step is not the first sleep step, the controller 180 can determine whether the current time has passed more than 30 minutes from the reference alarm time (S338).

If the current time has not passed 30 minutes from the reference alarm time, the controller 180 may return to step S440 to further collect the movement of the housing 101 through the motion detector 142. In this case, the controller 180 determines the sleep stage again based on the detected motion of the housing 101 and then determines whether it corresponds to the first sleep stage. If the current time passes more than 30 minutes from the reference alarm time, the controller 180 immediately outputs an alarm at the current time.

If the determined sleep step is the first sleep step, the controller 180 may determine whether the current time determined as the first sleep step falls within 30 minutes before and after the reference alarm time set by the user (S444). However, the time range of 30 minutes is limited to the present embodiment, and the numerical value of the time range is not limited thereto. The time range is a criterion for determining the boundary of how far the actual alarm output time can be from the reference alarm time set by the user, and may be changed larger or smaller by the user.

If the time of the first sleep step falls within 30 minutes before and after the reference alarm time, the controller 180 may output the alarm at the current time by changing the actual alarm output time to the current time (S446). In this case, as shown in FIGS. 5A and 5B, the actual alarm output time (7:20 AM and 7:30 AM) is equal to the reference alarm time (7:45 AM) within 30 minutes before and after the reference alarm time. It may be changed differently. At the actual alarm output time, the user was in the first sleep stage and can easily hear and wake the alarm sound.

The controller 180 may change the alarm time only to a time within 30 minutes before the reference alarm time, or may change the alarm time only to a time within 30 minutes after the reference alarm time. To this end, the controller 180 determines whether the current time determined as the first sleep step in step S444 belongs only within 30 minutes before the reference alarm time preset by the user, or only within 30 minutes after the reference alarm time. You can judge.

If the time when the first sleep stage is detected does not belong within 30 minutes before and after the reference alarm time, the controller 180 may determine whether the current time is more than 30 minutes after the reference alarm time (S448). If the current time passes more than 30 minutes from the reference alarm time, the controller 180 may immediately output an alarm (S446) to prevent the actual alarm time from moving further from the reference alarm time. If the current time has not passed the reference alarm time, the controller 180 may return to step S440 to further collect the movement of the housing 101 through the motion detector 142.

According to the present embodiment, the mobile terminal 100 may output an alarm when the user is sleeping in the first sleep stage. As a result, the user can hear the alarm and effectively wake up, and the fatigue when the user wakes up can be reduced. In addition, by detecting the movement of the housing 101 at different time intervals according to the power remaining amount of the battery 191 of the mobile terminal 100, the power of the mobile terminal 100 is prevented from being turned off due to excessive battery 191 consumption. can do.

Hereinafter, another specific embodiment of the control method that may be implemented in the mobile terminal 100 configured as described above will be described with reference to FIGS. 6 to 9. 6 to 9 illustrate control flow charts of the mobile terminal 100 according to various embodiments of the present invention, respectively.

According to an embodiment, the controller 180 may control the motion detector 142 to be deactivated when the remaining amount of power of the battery 191 decreases below a preset reference power amount. In this case, when the power remaining amount of the battery 191 is not large, the motion detector 142 may be activated to prevent the battery 191 from being discharged. As a result, the power of the mobile terminal 100 is turned off by the motion detection operation of the housing 101 of the motion detection unit 142, thereby preventing the alarm from sounding.

According to another embodiment, when the battery 191 is being charged, the controller 180 may control the motion detector 142 to be continuously activated until an alarm is output. When the battery 191 is being charged, it is not necessary to activate the motion detector 142 at regular time intervals to reduce battery 191 consumption. Therefore, when the battery 191 is being charged, the controller 180 can continuously activate the motion detector 142 to monitor the sleep stage of the user's sleep.

The detailed control flow of the mobile terminal 100 according to the embodiment is as shown in FIG.

First, as shown in FIG. 6, the controller 180 may determine whether the battery 191 is being charged (S510). When the battery 191 is being charged, the controller 180 continuously activates the motion detector 142 until an alarm is output (S520), and as a result, the motion detector 142 is configured to be connected to the housing 101. The movement may be continuously detected (S430).

In this case, the sleep state graph with respect to the sleep time may be shown as shown in FIG. 7. The motion detector 142 may be continuously activated until the alarm is output after the user sleeps to continuously detect the movement of the user's sleep. As illustrated in FIG. 7, when it is determined that the movement of the user's sleep detected by the motion detector 142 corresponds to the first sleep stage, an alarm may be output at that time. Thus, the actual alarm output time (7:20 am) may be different from the reference alarm time (7:45 am) set by the user.

If the battery 191 is not being charged, the controller 180 checks the power remaining amount of the battery 191 (S410). The controller 180 confirming the remaining power level of the battery 191 may compare the checked remaining power level with the preset reference power level, and determine whether the remaining power level of the battery 191 is greater than or equal to the reference power level (S610). . If the remaining amount of power of the battery 191 is greater than or equal to the reference amount of power, the controller 180 activates the motion detector 142 at a time interval corresponding to the confirmed remaining amount of power of the battery 191 (S420). A time interval corresponding to the remaining amount of power of the battery 191 may be set in advance, and subsequent control steps will be omitted as described above with reference to FIG. 4.

If the remaining amount of power of the battery 191 is less than the reference power amount, the controller 180 deactivates the motion detector 142 (S620), and outputs an alarm at the reference alarm time set by the user. It may be controlled (S630). In this case, the battery 191 does not have enough power remaining to detect the sleep state during sleep, and the mobile terminal 100 may operate to faithfully the conventional alarm function that outputs an alarm at a preset time.

According to another embodiment, the mobile terminal 100 of the present invention may further include an illumination sensor 143 as shown in FIG. The illuminance sensor 143 may measure illuminance around the mobile terminal 100, and may include an illuminance sensor for this purpose. In this case, the controller 180 may control the motion detection unit 142 to be activated only when the measured peripheral illuminance is equal to or greater than a preset reference illuminance. By outputting the alarm only when the illuminance around the user is above a certain value, the mobile terminal 100 may output the alarm only when the day is bright.

Detailed control flow of the mobile terminal 100 according to the present embodiment is as shown in FIG.

In the present embodiment, as shown in FIG. 8, the illuminance sensor 143 may measure the peripheral illuminance prior to the operation of the controller 180 (S710). When the illuminance detecting unit 143 measures the peripheral illuminance, the controller 180 compares the measured peripheral illuminance with a preset reference illuminance to determine whether the peripheral illuminance is greater than or equal to the preset reference illuminance (S720).

If the measured peripheral illuminance is greater than or equal to the reference illuminance, the controller 180 checks the remaining amount of power of the battery 191 (S410) and the motion detection unit 142 at a time interval corresponding to the checked remaining amount of power of the battery 191. Activate (S420). A time interval corresponding to the remaining amount of power of the battery 191 may be set in advance, and subsequent control steps will be omitted as described above with reference to FIG. 4.

If the measured peripheral illuminance is smaller than the reference illuminance, the controller 180 can deactivate the motion detector 142 (S730) and control the alarm unit 153 to output an alarm at a reference alarm time set by the user. There is (S740). In this way, when the ambient illuminance is not sufficient, that is, when the day is not bright, the mobile terminal 100 may operate to faithfully the conventional alarm function that outputs an alarm at a preset time.

According to another embodiment, the memory 160 included in the mobile terminal 100 of the present invention may store one or more alarm modes set according to a person's condition or weather type. In this case, the controller 180 may control the reference alarm time to be automatically changed according to the alarm mode selected by the user among the one or more alarm modes stored in the memory 160.

The alarm mode may be set according to a person's condition or weather type. For example, an alarm mode according to the user's condition may be set, such as "tired day", "next day of drinking", "fresh day". Alternatively, an alarm mode according to the type of weather may be set, such as "cloudy day", "rainy day", or "sunny day".

The alarm mode as described above serves as a criterion for determining whether to change the reference alarm time before or after the time set by the user, and also as a criterion for determining how to change the reference alarm time. For example, in the alarm mode of the “tired day”, the reference alarm time may be set to be one hour after the reference alarm time set by the user. In addition, in the “sunny day” alarm mode, the reference alarm time may be set to be 30 minutes before the time set by the user.

According to the present embodiment, the reference alarm time may be automatically changed according to the alarm mode selected by the user. The mobile terminal 100 may output an alarm during the first stage sleep closest to the changed reference alarm time. As a result, external factors such as the user's condition and weather can be considered in determining the alarm time, and the user does not need to reset the alarm time every time according to his condition or weather, thereby improving usability.

Detailed control flow of the mobile terminal 100 according to the embodiment is as shown in FIG.

As shown in FIG. 9, a reference alarm time may first be set by a user (S810). For example, the user may set the reference alarm time to 7 am. In a state where the reference alarm time is set, the user may select an alarm mode (S820). As in the previous example, the user can select a "tired day" mode.

If the "tired day" mode is selected by the user, the controller 180 automatically changes the reference alarm time according to the selected alarm mode (S830). As described above, the "tired day" mode may be a mode for changing the reference alarm time to one hour later than the time set by the user. In this case, the controller 180 may automatically change the reference alarm time to 8:00 am.

When the reference alarm time is changed by the controller 180, the controller 180 checks the remaining power of the battery 191 (S410), and the controller 180 moves at a time interval corresponding to the confirmed remaining power of the battery 191. Activate the sensing unit 142 (S420). A time interval corresponding to the remaining amount of power of the battery 191 may be set in advance, and subsequent control steps will be omitted as described above with reference to FIG. 4.

According to an embodiment of the present disclosure, the controller 180 of the mobile terminal 100 of the present invention may control the display unit 151 to display a graph indicating a change in movement of the housing 101 over time. In this case, the graph may indicate a change in the size of the movement of the housing 101 over time, or may indicate the frequency per hour of movement of the housing 101 over time. Alternatively, as illustrated in FIGS. 5A and 5B, the sleep stage determined by the controller 180 may be displayed over time. Through the graph, the user can check his or her sleep pattern through the graph and monitor the operation of the mobile terminal 100.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
