Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The memory 170 may be a flash memory type, a hard disk type, a solid state disk type, an SDD type (Silicon Disk Drive type), a multimedia card micro type ), Card type memory (e.g., SD or XD memory), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read memory, a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and / or an optical disk. The mobile terminal 100 may operate in association with a web storage that performs the storage function of the memory 170 on the Internet.

Meanwhile, as described above, the control unit 180 controls the operations related to the application program and the general operation of the mobile terminal 100. [ For example, when the state of the mobile terminal meets a set condition, the control unit 180 can execute or release a lock state for restricting input of a user's control command to applications.

In addition, the control unit 180 performs control and processing related to voice communication, data communication, video call, or the like, or performs pattern recognition processing to recognize handwriting input or drawing input performed on the touch screen as characters and images, respectively . Further, the controller 180 may control any one or a plurality of the above-described components in order to implement various embodiments described below on the mobile terminal 100 according to the present invention.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components. The power supply unit 190 includes a battery, the battery may be an internal battery configured to be chargeable, and may be detachably coupled to the terminal body for charging or the like.

In addition, the power supply unit 190 may include a connection port, and the connection port may be configured as an example of an interface 160 through which an external charger for supplying power for charging the battery is electrically connected.

As another example, the power supply unit 190 may be configured to charge the battery in a wireless manner without using the connection port. In this case, the power supply unit 190 may use at least one of an inductive coupling method based on a magnetic induction phenomenon from an external wireless power transmission apparatus and a magnetic resonance coupling method based on an electromagnetic resonance phenomenon Power can be delivered.

In the following, various embodiments may be embodied in a recording medium readable by a computer or similar device using, for example, software, hardware, or a combination thereof.

Meanwhile, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user mainly grasps and uses. These wearable devices include smart watch, smart glass, and head mounted display (HMD). Hereinafter, examples of a mobile terminal extended to a wearable device will be described.

The wearable device can be made to be able to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. If the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least a part of the data processed by the mobile terminal 100 to the wearable device 100 via the short- Lt; / RTI > Accordingly, the user can use the data processed by the mobile terminal 100 through the wearable device. For example, when a telephone is received in the mobile terminal 100, it is possible to perform a telephone conversation via the wearable device or to confirm the received message via the wearable device when a message is received in the mobile terminal 100 .

2 is a perspective view showing an example of a watch-type mobile terminal 300 according to another embodiment of the present invention.

2, a watch-type mobile terminal 300 includes a main body 301 having a display unit 351 and a band 302 connected to the main body 301 and configured to be worn on the wrist. In general, mobile terminal 300 may include features of mobile terminal 100 of Figure 1 or similar features.

The main body 301 includes a case that forms an appearance. As shown, the case may include a first case 301a and a second case 301b that provide an internal space for accommodating various electronic components. However, the present invention is not limited to this, and one case may be configured to provide the internal space, so that a mobile terminal 300 of a unibody may be realized.

The watch-type mobile terminal 300 is configured to allow wireless communication, and the main body 301 may be provided with an antenna for the wireless communication. On the other hand, the antenna can expand its performance by using a case. For example, a case comprising a conductive material may be configured to electrically connect with the antenna to extend the ground or radiating area.

A display unit 351 is disposed on a front surface of the main body 301 to output information, and a touch sensor is provided on the display unit 351 to implement a touch screen. The window 351a of the display unit 351 may be mounted on the first case 301a to form a front surface of the terminal body together with the first case 301a.

The main body 301 may include an acoustic output unit 352, a camera 321, a microphone 322, a user input unit 323, and the like. When the display unit 351 is implemented as a touch screen, the display unit 351 may function as a user input unit 323, so that the main body 301 may not have a separate key.

The band 302 is worn on the wrist so as to surround the wrist and can be formed of a flexible material for easy wearing. As an example, the band 302 may be formed of leather, rubber, silicone, synthetic resin, or the like. In addition, the band 302 is detachably attached to the main body 301, and can be configured to be replaceable with various types of bands according to the user's preference.

On the other hand, the band 302 can be used to extend the performance of the antenna. For example, the band may include a ground extension (not shown) that is electrically connected to the antenna and extends the ground region.

The band 302 may be provided with a fastener 302a. The fastener 302a may be embodied by a buckle, a snap-fit hook structure, or a velcro (trademark), and may include a stretchable section or material . In this drawing, an example in which the fastener 302a is embodied as a buckle is shown.

3 is a perspective view showing an example of a glass-type mobile terminal 400 according to another embodiment of the present invention.

The glass-type mobile terminal 400 is configured to be worn on the head of a human body, and a frame unit (case, housing, etc.) for the mobile terminal 400 may be provided. The frame portion may be formed of a flexible material to facilitate wearing. This figure illustrates that the frame portion includes a first frame 401 and a second frame 402 of different materials. In general, the mobile terminal 400 may include features of the mobile terminal 100 of FIG. 1 or similar features.

The frame portion is supported on the head portion, and a space for mounting various components is provided. As shown in the figure, electronic parts such as the control module 480, the sound output module 452, and the like may be mounted on the frame part. Further, a lens 403 covering at least one of the left eye and the right eye may be detachably mounted on the frame portion.

The control module 480 controls various electronic components included in the mobile terminal 400. The control module 480 can be understood as a configuration corresponding to the control unit 180 described above. This figure illustrates that the control module 480 is provided in the frame portion on one side of the head. However, the position of the control module 480 is not limited thereto.

The display unit 451 may be implemented as a head mounted display (HMD). The HMD type refers to a display method that is mounted on a head and displays an image directly in front of the user's eyes. When the user wears the glass-type mobile terminal 400, the display unit 451 may be arranged to correspond to at least one of the left and right eyes so that the user can directly provide an image in front of the user's eyes. In this figure, the display unit 451 is located at a portion corresponding to the right eye so that an image can be output toward the user's right eye.

The display unit 451 can project an image to the user's eyes using a prism. Further, the prism may be formed to be transmissive so that the user can view the projected image and the general view of the front (the range that the user views through the eyes) together.

As described above, the image output through the display unit 451 may be overlapped with the general view. The mobile terminal 400 can provide an Augmented Reality (AR) in which a virtual image is superimposed on a real image or a background and displayed as a single image using the characteristics of the display.

The camera 421 is disposed adjacent to at least one of the left eye and the right eye, and is configured to photograph a forward image. Since the camera 421 is positioned adjacent to the eyes, the camera 421 can acquire a scene viewed by the user as an image.

Although the camera 421 is provided in the control module 480 in this figure, it is not limited thereto. The camera 421 may be installed in the frame portion, or may be provided in a plurality of ways to obtain a stereoscopic image.

The glass-type mobile terminal 400 may include user input units 423a and 423b operated to receive control commands. The user input units 423a and 423b can be employed in any manner as long as the user operates in a tactile manner such as a touch or a push. This figure illustrates that the frame unit and the control module 480 are provided with user input units 423a and 423b of a push and touch input method, respectively.

In addition, the glass-type mobile terminal 400 may be provided with a microphone (not shown) for receiving sound and processing it as electrical voice data and an acoustic output module 452 for outputting sound. The sound output module 452 may be configured to transmit sound in a general sound output mode or a bone conduction mode. When the sound output module 452 is implemented in a bone conduction manner, when the user wears the mobile terminal 400, the sound output module 452 is brought into close contact with the head and vibrates the skull to transmit sound.

Hereinafter, embodiments related to a control method that can be implemented in a mobile terminal configured as above will be described with reference to the accompanying drawings. 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.

4 is a flowchart of a method of controlling a mobile terminal according to a first embodiment of the present invention. 5 and 7 are views for explaining a must alarm setting according to an embodiment of the present invention.

The control method of the mobile terminal according to the first embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, the control method of the mobile terminal according to the first embodiment of the present invention and the operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the necessary drawings.

In the first embodiment of the present invention, when the remaining battery level falls below a predetermined reference value, it means that the alarm is immediately output regardless of the originally set alarm time. Hereinafter, this will be described on the premise.

Referring to FIG. 4, the controller 180 may store at least one alarm information including a time at which the alarm is output in the memory 170 (S100).

Referring to FIG. 5, a front view of the mobile terminal 100 is shown. In the sound output unit 152, an alarm is output in a sound of a predetermined format at a time set as the alarm time. The battery indicator (1) indicates the current remaining battery level of the mobile terminal (100). The time indication (2) indicates the current time.

When the controller 180 receives an input for setting an alarm from the user, the control unit 180 can display an alarm setting screen 10 on the touch screen 151 in which an alarm can be set, as shown in FIG. According to one example, the alarm setting screen may be an execution screen of the alarm setting application. However, the present invention is not limited to a specific format, and can be applied to any format as long as it is an application program capable of setting an alarm.

The control unit 180 can display the alarm time setting area 20, the repeat setting area 30 and the must alarm setting area 40 on the displayed alarm setting screen 10. However, the present invention is not limited to this, and the alarm setting screen 10 may further display a separate setting area for setting other functions related to the alarm.

The user can set the alarm time through the alarm time setting area 20. [ For example, when the user touches the alarm time setting area 20, the controller 180 may display a separate setting window for setting the alarm time. When the alarm time is inputted through the setting window, the controller 180 can store the inputted alarm time in the memory 170 as alarm information.

The user can select the day of the week for which the set alarm time is repeatedly applied through the repeat setting area 30. [ If the day of the week in which the alarm is to be repeated is selected in the repeat setting area 30, the controller 180 may store the day of the week selected for outputting the alarm as alarm information in the memory 170. [

The user can set the must alarm operation for the set alarm time through the must alarm setting area 40. [ When there is a selection input in the setting box 41 of the must-alarm setting area 40, the controller 180 may store in the memory 170 as alarm information that the must-alarm has been set for the set alarm time.

Referring again to FIG. 4, the battery gauge 143 senses the remaining battery level of the mobile terminal 100 and outputs information on the detected remaining battery level to the controller 180 (S110).

The battery gauge 143 may output information on the battery remaining amount at predetermined time intervals under the control of the control unit 180. [ However, the present invention is not limited to this, and information on the remaining battery level may be continuously output to the control unit 180.

The control unit 180 may monitor whether the detected remaining battery level falls below a first reference value (S120).

The first reference value for the battery remaining amount may be preset to a very low value (e.g., 2% of the battery remaining amount) before the power of the mobile terminal 100 is turned off. However, the present invention is not limited thereto, and may be preset to a specific value as required.

The must alarm can be set for each of a plurality of alarms as required. According to an example, the first reference value may be set differently for each must-alarm.

The control unit 180 may continuously monitor the remaining battery level before the detected remaining battery level falls below the first reference value.

The control unit 180 may output a preset alarm when the remaining battery level falls below the first reference value [S130].

Referring to FIG. 6, a screen in which a must alarm is output when the remaining battery level falls below the first reference value is shown. The exclamation mark of the battery indicator 1 indicates that the remaining battery power of the mobile terminal 100 is almost zero.

Referring again to FIG. 5, it can be seen that an alarm has been set at 7:10 am in the alarm time setting area 20. FIG. The time display (2) indicates that the current time is 6:50 am. That is, when the battery remaining amount falls below the first reference value, the controller 180 can output the alarm set as the must alarm even before 7:10 am, which is the original alarm time.

According to one example, when the alarm is set to sound, the control unit 180 can output the alarm through the sound output unit 152. [ However, the present invention is not limited to this, and the alarm may be output as vibration, screen lighting, etc. as necessary.

The control unit 180 may display an alarm window and a notification window 50 on the touch screen 151 indicating that the alarm is due to the must alarm operation. Through this, the user can immediately know the reason why the alarm was not made at the set time.

In FIG. 6, it is assumed that one must alarm is set. However, the present invention is not limited to this. When a plurality of must alarms having the same first reference value are set, the controller 180 can display information about the plurality of must alarms.

Accordingly, the user can recognize the set alarm before the battery of the mobile terminal 100 is discharged and the power is turned off, thereby preventing an important alarm from being missed.

FIG. 7 shows a menu 21 for setting a time interval for setting a time interval in which a must alarm is to be operated.

The control unit 180 may output an alarm according to the must-alarm in a preset time interval. Referring to FIG. 7, the user can set a time interval for the must-alarm through the menu for setting the must-alarm time interval 21 on the alarm setting screen 10.

When the user touches the section start point setting area 22 and the section end point setting area 23, the controller 180 may display a separate setting window for setting the time. When the time is inputted through the setting window, the control unit 180 may store the alarm time interval according to the input start time and end time of the interval as alarm information in the memory 170.

Thus, if the duration of the must-be alarm is set, the controller 180 can output the set alarm regardless of the alarm time if the battery remaining amount falls below the first reference value only within the set time period. That is, the controller 180 may not output an alarm even if the battery remaining amount falls below the first reference value at a time other than the must-alarm time interval.

For example, the user can set his / her sleeping time as a must-alarm time interval. In this case, the controller 180 may perform the must alarm operation before the battery is discharged during the user's sleeping. Accordingly, the user can be prevented from failing to recognize the alarm set as the battery discharge during the sleeping.

In addition, the user can operate the must alarm only in a desired time period, thereby preventing an alarm from being output in advance in an undesired time period.

The repeat setting area 30 and the must alarm setting area 40 shown in FIG. 7 are substantially the same as those described in FIG. 5, and therefore detailed description thereof will be omitted.

8 is a flowchart of a method of controlling a mobile terminal according to a second embodiment of the present invention. 9 and 10 illustrate transmission of alarm information to an external device according to an embodiment of the present invention.

The control method of the mobile terminal according to the second embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, the control method of the mobile terminal according to the second embodiment of the present invention and the operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the necessary drawings.

In the second embodiment of the present invention, when the remaining battery level falls below a predetermined reference value, it means that the originally set alarm information is transmitted to the external device. Hereinafter, this will be described on the premise.

Referring to FIG. 8, the controller 180 may store at least one alarm information including a time at which the alarm is output in the memory 170 (S200).

In this case, as described above, the user can set a must alarm in setting the alarm information.

The battery gauge 143 senses the remaining battery power of the mobile terminal 100 and outputs information on the detected remaining battery power to the controller 180 (S210).

Steps S200 and S210 are substantially the same as steps S100 and S110 of FIG. 4 described above, so that detailed description thereof will be omitted here.

The controller 180 may monitor whether the detected remaining battery level falls below a second reference value [S220].

The second reference value for the battery remaining amount may be set to a very low value before the power of the mobile terminal 100 is turned off. According to an example, the second reference value may be set to a value lower than the first reference value (for example, 1% of the battery remaining amount). However, the present invention is not limited thereto, and may be preset to a specific value as required.

The must alarm can be set for a plurality of alarms as required. According to an example, the second reference value may be set differently for each must-alarm.

The control unit 180 may continuously monitor the remaining battery level before the detected remaining battery level falls below the second reference value.

If the detected battery remaining amount falls below the second reference value, the controller 180 may detect whether there is an external device capable of transmitting a first signal to output an alarm at a predetermined alarm time (S230) .

Referring to FIG. 9, the mobile terminal 100 may be connected to the external devices 200, 300, and 400 through the communication network 500. The communication network 500 can be applied to any case where it can be connected to an external device through the wireless communication unit 110 regardless of the term.

9, a mobile terminal 200, a watch-type mobile terminal 300, and a glass-type mobile terminal 400 are shown as external devices, but the present invention is not limited thereto. The external device may be any device capable of receiving an alarm signal to output an alarm from the mobile terminal 100 and outputting an alarm.

If there is no external device to transmit the first signal through the communication network 500, the controller 180 may output information indicating that the first signal is not transmitted (S240).

If there is no external device to transmit the first signal as a result of searching for the external device, the controller 180 can display the information through the notification window 51 as shown in FIG. However, the present invention is not limited thereto, and the controller 180 may display the information in a format other than the notification window.

When the user selects the external device search 52, the control unit 180 can search through the wireless communication unit 110 to determine whether there is an external device connectable. According to an example, when a connectable external device is found, the controller 180 may transmit the first signal to the searched external device. If the user later selects (53), the control unit 180 can terminate the display of the notification window 51. [

Accordingly, the user can easily know whether there is an external device capable of transmitting the first signal according to the must alarm operation, and can take measures accordingly.

Referring back to FIG. 8, when the external device exists, the controller 180 may transmit the first signal to the external device (S250).

The external device that receives the first signal from the control unit 180 can output an alarm according to the originally set alarm time. According to an example, the format of the output alarm may be set to the format of the originally set alarm (for example, when the vibration is set, the external device also outputs an alarm by vibration).

However, the present invention is not limited to this, and the first signal may be set so that the external device outputs an alarm in a format different from the format of the originally set alarm.

Accordingly, even when the battery of the mobile terminal is discharged before the set alarm time, the user can recognize the alarm output from the external device. For example, in the case of using the watch-type mobile terminal 300 or the glass-type mobile terminal 400 described in FIG. 2 or FIG. 3 together, can do.

Referring to FIG. 8, after the controller 180 transmits the first signal to the external device, the battery gauge 143 may sense the remaining battery level of the mobile terminal 100 (S260). In this case, the control unit 180 may monitor whether the remaining battery level of the mobile terminal rises again to a level higher than the third reference value (S270).

The user may charge the battery after the battery remaining amount of the mobile terminal 100 falls below the second reference value. In this case, the mobile terminal 100 is not discharged until the set alarm time, so that the mobile terminal 100 can output an alarm in a redundant manner with the external device.

Accordingly, the controller 180 may transmit a second signal to cancel the output of the alarm according to the first signal to the external device (S280).

In this case, the third reference value for the battery remaining amount may be set to a value higher than the second reference value (for example, the battery remaining amount 10%). However, the present invention is not limited to this, and the third reference value may be preset to a specific value. In this case, it may be desirable that the battery is set to discharge on the premise that the battery is not discharged until the alarm time.

According to an example, the controller 180 may calculate the battery consumption rate for a predetermined time period from the present time. Thereafter, the controller 180 may calculate the remaining battery level at which the battery is discharged or does not fall below the second reference value for the remaining time until the set alarm time, and may set the remaining battery level as the third reference value.

When the battery remaining amount of the mobile terminal 100 is equal to or more than the third reference value, the controller 180 transmits a second signal for canceling the alarm output according to the first signal transmitted to the external device to the external device . Thus, the setting of the alarm output by the first signal can be canceled by the external device.

Accordingly, the user can prevent the alarm from being output in a redundant manner from the external terminal 100 and the external device that receives the first signal.

The first and second embodiments of the present invention described above can be implemented together or independently as needed.

According to an example, when the first embodiment and the second embodiment of the present invention are performed together, the second reference value may be set lower than the first reference value. The control unit 180 outputs the set alarm when the remaining battery level falls below the first reference value for the alarm for which the must alarm has been set and returns the first signal to the external device Lt; / RTI >

In this case, in the mobile terminal 100, the alarm by the must alarm can be output before the alarm time. Also, in an actual alarm time, an alarm may be output from an external device that has received the first signal.

Accordingly, even if the user does not recognize the alarm output from the mobile terminal 100, the user can recognize the alarm output from the external device again.

In the above description, the second reference value is lower than the first reference value, but the present invention is not limited thereto. The second reference value may be equal to or higher than the first reference value. In this case, an operation similar to that described above is performed, and thus a detailed description thereof will be omitted.

11 is a flowchart of a method of controlling a mobile terminal according to a third embodiment of the present invention.

The control method of the mobile terminal according to the third embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, the control method of the mobile terminal according to the third embodiment of the present invention and the operation of the mobile terminal 100 for implementing the same will be described in detail with reference to the necessary drawings.

In the third embodiment of the present invention, when the power of the mobile terminal 100 is turned off, it may mean that originally set alarm information is transmitted to an external device. Hereinafter, this will be described on the premise.

Referring to FIG. 11, the controller 180 may store in the memory 170 at least one alarm information including a time at which the alarm is output (S300).

In this case, as described above, the user can set a must alarm in setting the alarm information.

In the case of step S300, since it is substantially the same as the step S100 of FIG. 4 described above, further detailed description will be omitted here.

The controller 180 may monitor a signal for turning off the power of the mobile terminal 100 (S310).

For example, the signal to turn off the power may be when the user presses the power button for a long time, selects a power-off menu, or discharges the battery. However, the present invention is not limited thereto and can be applied to any case where the power of the mobile terminal 100 is turned off.

Even in this case, the must alarm can be set for a plurality of alarms as required.

If there is a signal to turn off the power, the controller 180 may detect whether there is an external device capable of transmitting a third signal for outputting an alarm at the set alarm time (S320).

This is substantially the same as the description of FIG. 8 and FIG. 9 described above, so that a detailed description will be omitted here.

When there is no external device to transmit the third signal through the communication network 500, when the mobile terminal 100 is turned on again, the controller 180 outputs information informing that the third signal is not transmitted (S330).

When the power of the mobile terminal 100 is turned on again, the controller 180 may display information indicating that there is no external device to transmit the third signal through the notification window 51, as shown in FIG. However, the present invention is not limited thereto, and the controller 180 may display the information in a format other than the notification window.

When the user selects the external device search 52, the control unit 180 can search through the wireless communication unit 110 to determine whether there is an external device connectable. According to an example, when a connectable external device is found, the controller 180 may transmit the third signal to the searched external device when the mobile terminal 100 is turned off. If the user later selects (53), the control unit 180 can terminate the display of the notification window 51. [

Through this, the user can easily know whether there is an external device capable of transmitting the third signal according to the must alarm operation, and can take measures accordingly.

Referring again to FIG. 11, when the external device exists, the controller 180 may transmit the third signal to the external device (S340).

The external device that receives the third signal from the control unit 180 can output an alarm according to the originally set alarm time. According to one example, the format of the output alarm may be set to the format of the originally set alarm (for example, when the vibration is set, the external device also outputs an alarm by vibration).

However, the present invention is not limited to this, and the third signal may be set so that the external device outputs an alarm in a format different from the format of the originally set alarm.

Accordingly, even when the mobile terminal 100 is turned off before the set alarm time, the user can recognize the alarm through the external device.

Referring to FIG. 11, the controller 180 may transmit a fourth signal for canceling the output of the alarm according to the third signal to the external device (S350).

When the power of the mobile terminal 100 is turned on before the set alarm time, the controller 180 may transmit a fourth signal to the external device to cancel the alarm output according to the third signal transmitted to the external device. Thus, the external device can cancel the setting of the alarm output by the third signal.

Accordingly, the user can prevent the alarm from being output redundantly from the external terminal 100 and the external device that receives the third signal.

The first embodiment, the second embodiment and the third embodiment of the present invention described above can be implemented together or independently as needed.

12 is a view for explaining the setting of the sleep time interval according to the illuminance information and the setting of the must alarm in the sleep time interval according to the embodiment of the present invention.

The control unit 180 may obtain the sleep time interval according to the illumination information detected by the illumination sensor 142. [ According to one example, the illumination information table may be stored in the memory 170. [ The control unit 180 may store the illuminance information detected by the illuminance sensor 142 in the illuminance information table according to a predetermined time interval.

According to the stored illumination information, the controller 180 can calculate the sleep time interval of the user by day of the week. According to an example, when the illuminance is remarkably low during a specific time interval, the controller 180 may calculate the specific time interval as a sleep time interval.

However, the present invention is not limited thereto, and acoustic information using the microphone 122 may be used in addition to the illuminance information. For example, when the controller 180 detects only a sound of a predetermined value or less, the control unit 180 can determine the sleep time.

In addition, the controller 180 may determine that the mobile terminal 100 is not moving for a predetermined period of time as the sleep time. As described above, any information that can be detected by the mobile terminal 100 as information that can be determined as the sleeping time can be applied.

When the sleep time interval is obtained, the controller 180 may display a notification window 70 for setting the sleep time interval as a must alarm, as shown in FIG. 12 (a).

If the user has made a selection of accepting it, the control unit 180 can display the sleep time interval must-alarm setting screen 80 as shown in FIG. 12 (b). In Fig. 12 (b), a sleep time interval 81 on Sunday and a sleep time interval 82 on Monday are displayed.

According to an example, when the user selects the sleeping time interval for each day of the week, the controller 180 may display a setting window for resetting the sleeping time interval. Through this, the user can easily change the desired time.

As shown in FIG. 12 (b), the user can input a flicking. The flicking input means an operation of touching the touch screen 151 and moving the contact in a specific direction (up, down, left, right or diagonal) and then releasing the contact. When the touch input by the flicking is received, the control unit 180 can sequentially display the sleep time interval for each set day of the week.

Referring to FIG. 12C, the controller 180 displays a sleep time interval 87 for Saturday, and displays a selection area 90 for whether to set a must alarm for the displayed sleep time interval .

When the user selects the must alarm for the sleep time interval, the controller 180 may store the alarm in the memory 170 as alarm information.

Thereafter, the controller 180 may perform the must alarm operation according to the first, second, or third embodiment of the present invention with respect to the sleep time interval.

In this way, the user can receive and use the so-called must alarm set automatically according to his / her sleeping time.

13 is a view for explaining the setting of a must-alarm by a specific touch input according to an embodiment of the present invention.

13 (a) shows that a schedule setting screen 60 is displayed on the touch screen 151 of the mobile terminal 100. FIG. The user can set a specific time through the date setting area 61 and the time setting area 62. [ However, the present invention is not limited to this, and any screen that can set a specific time can be applied.

If a predetermined touch input is received, the control unit 180 sets a must alarm for the set specific time and stores it in the memory 170 as alarm information. Referring to FIG. 13 (b), it can be seen that a must-alarm has been set (41) for the time in the alarm setting screen 10.

Although shown in FIG. 13 (a) as three consecutive touch inputs. The predetermined touch input is not limited thereto. The predetermined touch input may be set by a predetermined tapping, dragging, flicking, press, multi-touch, or a combination thereof.

Thus, the user can quickly and easily set the must alarm without executing the alarm setting screen.
