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 100 satisfies a set condition, the controller 180 may 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 sensing unit 140 of the mobile terminal 100 according to an embodiment of the present invention may include a tab sensing unit for sensing a tab or a tab gesture that the user hits the main body or the display unit 151 (Not shown).

Here, the tab sensing unit may sense a gesture of tapping the main body of the mobile terminal 100 or the display unit 151. More specifically, the tab may be a tap object such as a finger or the like that lightly touches the body of the mobile terminal 100, the display unit 151, or an object or a tap object to the body of the mobile terminal 100, the display unit 151, It can be understood as an operation of making contact.

The tap object to which the tab is applied may be a main body of the mobile terminal 100, a display unit 151 or an object capable of applying an external force to an object. For example, a finger, a stylus pen, a pen, a pointer, a fist, and the like. The tap object is not limited to an object to which a touch input can be applied to the mobile terminal 100 according to the present invention. The tap object may be a touch panel that can apply an external force to the mobile terminal 100, the display unit 151, If it is an object, its kind is irrelevant.

Meanwhile, the object to which the tap gesture is applied may include at least one of a body of the mobile terminal 100 and an object on which the mobile terminal 100 is placed.

Meanwhile, in the present invention, the tap or tap gesture may be detected by at least one of the acceleration sensor and the touch sensor included in the tap sensing unit. Here, the acceleration sensor is a sensor capable of measuring dynamic force such as acceleration, vibration, shock, etc. of the main body of the mobile terminal 100.

That is, the acceleration sensor can detect movement (or vibration) of the main body of the mobile terminal 100 generated by the tap gesture and detect whether the tap is applied to the object. Therefore, the acceleration sensor detects a tap of the main body of the mobile terminal 100 or the touch screen, or detects the position of the main body of the mobile terminal 100, It is possible to detect that an object is tapped.

As long as the acceleration sensor can detect movement or vibration of the main body of the mobile terminal 100 as well as the case where the tap is applied to the main body 100 or the display unit 151 of the mobile terminal 100, It is possible to detect the tab even if it is applied to an off-site.

The mobile terminal 100 according to the present invention may use either one of the acceleration sensor and the touch sensor or the acceleration sensor and the touch sensor in order to detect the taps of the mobile terminal 100 or the display unit 151 Or an acceleration sensor and a touch sensor can be used at the same time. On the other hand, in order to sense a tap, a mode using only an acceleration sensor may be named as a first mode, a mode using a touch sensor may be referred to as a second mode, and both the acceleration sensor and the touch sensor may be used Mode) may be referred to as a third mode or a hybrid mode.

On the other hand, when the tab is sensed through the touch sensor, it is possible to more accurately grasp the position where the tab is sensed.

Meanwhile, in the mobile terminal 100 according to the present invention, in order to sense the tab through the acceleration sensor or the touch sensor, when the display unit 151 of the mobile terminal 100 is in a deactivated state, It can operate in a specific mode. This particular mode may be referred to as a 'doze mode'.

For example, in the doze mode, in a touch screen structure in which a touch sensor and a display unit 151 have a mutual layer structure, only a light emitting element for outputting a screen in the display unit 151 is turned off, The sensor may be in the on-state state. Alternatively, the doze mode may be a mode in which the display unit 151 is turned off and the acceleration sensor is kept in an on-state. Alternatively, the dose mode may be a mode in which the display unit 151 is turned off, and both the touch sensor and the acceleration sensor are kept on.

Therefore, when the user is in the doze mode, that is, when the display 151 is turned off, or when the display 151 is turned off (the display 151 is disabled) When the tab is applied to at least one point on the display unit 151 or a specific point of the display unit 151 of the mobile terminal 100 or the at least one of the touch sensors or the acceleration sensor, Can be detected.

Also, the tap detection unit can determine that a "tab" for controlling the mobile terminal 100 is detected only when at least two or more tabs are applied within the reference time. For example, when one tap is applied to the display unit 151 by a touch object capable of applying a touch to the display unit 151, the tab sensing unit can recognize the one tap as a touch input . That is, in this case, the control unit 180 does not control the function corresponding to the one tap, but the function corresponding to the touch input corresponding to the one tap (for example, A function of selecting an icon) can be controlled.

Accordingly, the control unit 180 may be configured to perform a 'tab' for controlling one or more functions only when at least two or more tabs (or a plurality of tabs) continuously detected within the reference time are detected by the tab detecting unit It can be judged that it has been detected.

That is, tap gestures may mean that at least two or more tap gestures are continuously sensed within a reference time. Accordingly, in the following description, the "tab" is detected, which means that it has been sensed that an object such as a user's finger or a touch pen is hit on the main body or the display unit 151 of the mobile terminal 100 a plurality of times .

In addition, the controller 180 may determine whether the tab is sensed by the user's other finger or one finger, as well as that the tab is sensed within the reference time. For example, when the tabs are sensed by the display unit 151, the controller 180 determines whether the tabs are formed through one finger or through different fingers Can be detected. Or the controller 180 recognizes the position of the taps on the display unit 151 or the acceleration generated due to the taps through at least one of the touch sensor and the acceleration sensor provided in the tap sensing unit, Or whether they are made through different fingers, respectively.

Further, the controller 180 may further determine whether the user has input the tabs through one hand or one finger, or whether the user has input through the two hands or at least two fingers It is possible to judge whether or not it is inputted.

The taps may be a plurality of tapes continuously sensed within the reference time. Here, the reference time may be a very short time, for example, 300 ms to 2 s or less.

If it is detected that the main body of the mobile terminal 100 or the display unit 151 is first tapped on the tap sensing unit, the tap sensing unit may perform tapping next to the first tapping within the reference time from the time when the first tapping is detected Can be detected. If the next tap is detected within the reference time, the tap sensing unit or the controller 180 may determine that the tap for controlling the specific function of the mobile terminal 100 has been sensed according to the embodiment of the present invention have. In this way, the controller 180 recognizes the tab as a valid tap only when the second tab is detected within a predetermined time after the first tab is detected, thereby determining whether the user wants to control the mobile terminal 100, It is possible to distinguish whether a tab is added or not.

There are various methods for allowing the 'valid tap' to be recognized. For example, when the first tab is detected by the first reference count or by the first reference count, the controller 180 may detect the second tab by tapping the body by the second reference count or by the second reference count within a predetermined time, May be recognized as the " valid tap ". Here, the number of the first reference times and the number of the second reference times may be equal to or different from each other. For example, the first reference number may be one, and the second reference number may be two. As another example, the first reference number and the second reference number may all be one.

Also, the control unit 180 can determine that the "tabs " are detected only when the tab is within the" predetermined area ". That is, when it is detected that the main body of the mobile terminal 100 is tapped for the first time, the controller 180 may calculate a predetermined area from the point where the first tapping is detected. Then, the control unit 180 determines whether or not the first beat is followed by the first or second reference count or the first or second reference count or more within the reference time from the time when the first beat is detected, It can be determined that the first tab or the second tab is applied.

It is to be understood that the reference time and the predetermined region may be variously modified according to the embodiment.

Meanwhile, the first tap and the second tap may be sensed not only as a reference time and a predetermined area, but also as separate tabs depending on the detected position of each tab. That is, the controller 180 may determine that the first tab and the second tab are applied when the second tab is detected at a position spaced apart by a predetermined distance from the position where the first tab is sensed. When the first tap and the second tap are recognized based on the sensed position, the first tap and the second tap may be simultaneously detected.

Also, when the first tap and the second tap are configured by a plurality of touches, that is, a plurality of tapes, a plurality of touches constituting the first tap and the second tap may be simultaneously detected. For example, when the first touch constituting the first tab is detected and the first touch constituting the second tab is positioned at a position spaced apart from the position where the first touch of the first tab is sensed If it is sensed, the controller 180 can sense the first touch constituting the first tap and the second tap, respectively. The control unit 180 senses additional touch input sensed at each position and determines that the first tap and the second tap are applied when a touch is detected at a first reference frequency or at a second reference frequency at each of the positions can do.

If the tabs of the main body or the display unit 151 of the mobile terminal 100 are detected a plurality of times from the tab detection unit, the control unit 180 determines whether the tabs At least one of the functions can be controlled.

For example, the control unit 180 may control at least one of the functions executable on the mobile terminal 100 when the plurality of tabs meet the predetermined condition. For example, the controller 180 compares a predetermined plurality of touch input patterns with a pattern formed by the plurality of taps, and outputs the touch input patterns to the mobile terminal 100 according to any one of the plurality of predetermined touch input patterns. The lock state can be released. In this case, the controller 180 may perform any one of functions corresponding to any one of the touch input patterns.

Here, the function may mean all kinds of functions that can be executed or operated on the mobile terminal 100. [ For example, one of the functions may be an application installed in the mobile terminal 100. [ For example, " an arbitrary function is executed " may mean that " an arbitrary application is executed or driven in the mobile terminal 100 ".

As another example, the function may be a function necessary for basic operation of the mobile terminal 100. [ For example, the functions necessary for the basic operation may be a function of turning on / off the illumination provided on the display unit 151, switching the mobile terminal 100 from the released state to the locked state, A function of switching to the released state, a function of setting the communication network, a function of changing the setting information of the mobile terminal 100, and the like.
