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 fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation 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 senses 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, do.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. 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.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. 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 camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. 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 display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

Also, the display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image.

The use restriction function may include an application or content that consumes a large amount of current, such as a camera, the Internet, a game, music / video, and the like.

In the present invention, the release option for the use restriction function may be provided automatically upon entering the battery power saving mode or may be provided when the user selects a specific use restriction function. When provided automatically, all use restriction functions can be provided in a list form, and when a specific use restriction function is selected, information for asking whether to release the function can be displayed.

How to disable the use restriction function when the mobile phone is low

10 is a flowchart illustrating a method for controlling a mobile terminal when a remaining battery level is low according to the second embodiment of the present invention.

Referring to FIG. 10, the controller 180 may detect a user's application execution request (S300). The requested application may include currency, text, camera, internet, game, music / video. In response to the request, the controller 180 checks whether the remaining battery level is equal to or less than the first level after checking the remaining battery level (S310, S320).

If it is determined that the remaining battery level is equal to or less than the first level, the controller 180 may check whether the requested application is an application that is restricted to use (S330), and may provide an option to perform the application according to the check result. That is, if it is determined that the requested application is a limited-use application, the control unit 180 provides an option to temporarily release the use restriction of the requested application (S340).

The option is displayed in a pop-up form, and may include, for example, guidance information such as "Do you want to release the use restriction of the xxx application? &Quot;. If the user selects execution of the guide information, the control unit 180 enters the simple mode, and the user immediately executes the application without selecting a separate menu (S350). For example, when the user requests to use the camera, the camera function can be immediately executed to execute the continuous shooting function (continuous shooting function). Thereafter, the controller 180 continuously checks the remaining amount of the battery, and can perform the operation shown in FIG. 2 when the battery is discharged.

On the other hand, if the battery remaining amount is not equal to or lower than the first level in step S32, or if the application is not limited to use in step S330, the requested application is executed (S360).

11 to 13 are detailed embodiments of a method of controlling a mobile terminal when a remaining battery level is low according to the second embodiment of the present invention.

Referring to FIG. 11, when the mobile terminal reaches a predetermined level (eg, 5%), the controller 180 enters a low power mode to limit the use of a function having a relatively large current consumption, do.

When the user selects one of the limited functions that the user uses in the low power mode, for example, the camera function, the control unit 180 displays a pop-up 70 asking to cancel the camera use restriction. When the user selects to cancel the use restriction of the camera in the pop-up 70, the control unit 180 displays a preview screen, and photographs the subject continuously according to the user's shooting input, and then ends the camera function. In another embodiment, the control unit 180 may terminate the camera function after continuously photographing the subject immediately after the user selects to cancel the use restriction of the camera.

Meanwhile, when the mobile terminal reaches a predetermined level (eg, 5%) even if the user does not request execution of a specific application, the present invention displays information for releasing the use restriction through pop-up . The mode in which the information is displayed is referred to as a simple mode. The pop-up may include at least one terminal function and application whose usage is restricted in the low power mode.

If a specific application is selected in the pop-up, the controller 180 displays a simple mode of the application, that is, additional information that can execute or execute the application immediately. For example, as shown in FIG. 12A, if the camera function is selected in the pop-up, the controller 180 may switch to the immediate mode to continuously photograph the subject and then terminate the camera function. 12B, when the message function is selected in the pop-up, the controller 180 switches the mode to the immediate mode so that at least one sentence is recommended to be transmitted to the user without inputting a text message. If the sentence is selected, the corresponding message function is automatically terminated.

In this way, the user can temporarily release the limited use function when the remaining battery power is low, and can continuously photograph a plurality of pictures or transmit a pre-stored sentence to another user. In this case, since the function temporarily allowed to be used is terminated immediately after the corresponding function is performed in order to reduce battery consumption, it is difficult for the user to properly confirm the operation performed by the user.

Accordingly, when the first user recharges the battery or replaces the battery and then turns on the power again, the second user of the preset contact is informed that the mobile phone is turned on, It is possible to provide a method of displaying a result performed through a function temporarily permitted to be used.

FIG. 13 is an embodiment showing a result of performing a function in which the use restriction is temporarily released when the mobile phone is turned on.

As shown in FIG. 13, when the user turns on the power after charging the battery or replacing the battery, the pop-up 80 displays the type and function of the function whose use restriction is temporarily released on the idle screen do. For example, the function for which the use restriction is temporarily released may be a camera function.

When the user requests confirmation of the camera function, the control unit 180 displays four photographs photographed in the low power mode, and displays the transmitted text message when the user selects the text message function.

As described above, according to the present invention, when a cell phone (battery) is discharged, guide information informing that the power of the mobile phone is turned off is transmitted to the preset contact, The reason for disconnecting can be known to the other user.

Further, according to the present invention, when the mobile terminal is turned on again after being charged, the mobile terminal automatically sends the turned-on state of the mobile terminal to the predetermined contact, thereby informing the user of the user's usability.

Furthermore, the present invention provides an option that the user can selectively release the function of the use in the low power mode when the remaining capacity of the battery is exhausted and enters the low power mode, There is an effect that can be performed.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. 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.
