It can be made of a combination of.

Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a sensing signal corresponding thereto. The controller 180 may control driving or operation of the mobile terminal 100 or perform data processing, function or operation related to an application program installed in the mobile terminal 100 based on the sensing signal. 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 or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmissive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a high frequency oscillating proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object by the change of the electric field according to the proximity of the conductive object. 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, an action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching an object on a screen is called a "contact touch." The position at which the object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have. Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected 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. Further, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on 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) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. do.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different control or perform the same control according to the type of touch object that touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

The touch sensor may be configured to detect a touch input using different methods in the activated and deactivated state of the display unit 151. In this case, the different methods may be related to the activation period of the touch sensor. More specifically, the touch sensor may be activated at different periods depending on whether the display unit 151 is activated. That is, the touch sensor may sense a touch input applied to the touch sensor while having different activation cycles according to whether the display unit 151 is activated.

For example, when the display unit 151 is deactivated, the touch sensor may be activated at a predetermined specific period. In this case, the specific period may be a period corresponding to a time greater than zero. In addition, when the display unit 151 is activated, the touch sensor may be operated in an activated state at all times. That is, in this case, the activation period of the touch sensor may be zero or a period having a time very close to zero.

Whether or not the touch sensor is activated may be distinguished using power consumption of the touch sensor. For example, when the power consumption of the touch sensor is less than or equal to a preset reference value based on 0, the touch sensor corresponds to a deactivated state and when the power consumption of the touch sensor is greater than the preset reference value based on 0. , It can be said to be activated.

When the display unit 151 is in an active state (hereinafter referred to as an active mode), the touch sensor may continue to be activated and may wait for application of a touch input to the display unit 151. have. On the contrary, when the display unit 151 is in an inactive state (hereinafter referred to as a dose mode), the touch sensor may be activated every predetermined period.

On the other hand, the shorter the specific period of activation of the touch sensor, the faster the speed of detecting the touch input hitting the display unit 151, but accordingly the power consumed by the touch sensor may be increased. On the contrary, the longer the period in which the touch sensor is activated, the smaller the power consumed by the touch sensor, but the speed of detecting the touch input hitting the display unit 151 may be slower.

Accordingly, the specific period may be set to increase the efficiency of power consumption while being fast enough that the detection speed is not recognized by the user in detecting the touch input hitting the display unit 151. For example, the specific period may be set so that the touch sensor is deactivated and activated 20 times (1 Hz) per second.

Meanwhile, while the display unit 151 is activated, the touch sensor may also be activated, and in the activated state, the activation period T of the touch sensor may be zero or very close to zero. Alternatively, in the state in which the touch sensor is activated, the period of the touch sensor may be several times shorter than a specific period in which the touch sensor is activated in the state in which the display unit 151 is inactivated. That is, the touch sensor may be activated at different periods depending on whether the display unit 151 is activated.

Meanwhile, in the doze mode in which the display unit 151 is deactivated and the touch sensor is periodically activated, a predetermined touch input (for example, tapping a predetermined area continuously within a reference time) by the touch sensor is performed. When the first and second touch inputs are sensed, the controller 180 may switch the doze mode to an active mode in which the display unit and the touch sensor are activated.

In addition, the touch sensor may be driven at different periods based on the state of the display unit 151. For example, when the display unit 151 is in the closed state, the dose mode may be executed, and when the display unit 151 is switched from the closed state to the open state, the active mode may be executed.

Meanwhile, the touch sensor and the proximity sensor described above may be independently or combined, and may be a short (or tap) touch, a long touch, a multi touch, a drag touch on a touch screen. ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. A touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

2, the mobile terminal 100 according to the present invention may include a display unit 151, a sensing unit 140, and a controller 180.

The display unit 151 may be implemented as a touch screen capable of sensing a touch input.

The detector 140 may detect at least one sensor value for determining whether water is present on the display unit 151.

For example, the sensor value may include an electrical signal applied to the touch panel of the display unit 151, a touch pattern applied to a continuous touch input, a signal strength of a USB pin, a signal strength of an earphone port, and a camera lens. The value of the refraction of the light, atmospheric pressure change, and the like may be included.

The controller 180 may calculate the presence, location, and area of the 'moisture region' in which moisture exists on the display unit 151 based on the sensor value.

In addition, the controller 180 may ignore a signal corresponding to the touch input applied to the moisture region.

As another example, the controller 180 may detect a change in the size of the moisture region and process a signal corresponding to the touch input differently based on the changed size.

The moisture region may be defined as a region in which moisture exists on the display unit 151 or more. For example, an area of water droplets having a predetermined amount or more or a predetermined size (diameter) or more may be defined as a moisture area.

In an embodiment, when a plurality of water droplets are formed on the display unit 151, a region on the display unit 151 where each water droplet is formed may be defined as a moisture region.

In this case, the position of the moisture region may be defined as a coordinate value of each of the water droplets formed on the display unit 151. The area (size) of the moisture region may be defined as the size of the region occupied by each water drop or the sum thereof.

As another embodiment, the controller 180 may calculate (detect) the moisture region based on an electrical signal applied to the touch panel of the display unit 151.

Specifically, when moisture is present in the touch panel, a high electrical signal appears due to the conductivity of water. Based on this principle, the controller 180 may calculate a region where the electrical signal is greater than or equal to a predetermined value (for example, a region higher when the electrical signal is free of a medium) as a moisture region. And based on the coordinate value and area of the area | region whose electric signal is more than predetermined value, the position and area of a water | moisture area can be calculated.

As another embodiment, the controller 180 may calculate the moisture region based on a touch pattern in which a continuous touch input is applied to the display unit 151.

For example, when a touch signal is generated by multi-touch for a short time, it may be recognized that several droplets fall on the screen 151.

As another example, when the falling cycle is very short and repetitive, it may be recognized that the droplet falls on the screen 151.

As another example, when a multi-touch is generated and the touch area moves downward, which is recognized as a gyro sensor, it may be recognized that water droplets flow down the screen 151.

That is, according to the above-described embodiments, the presence, location, and area of the moisture region may be calculated, and the corresponding touch input may not be executed by recognizing that the touch input is by water.

As another embodiment, the controller 180 may prevent the touch input applied to the display unit 151 from being executed if the area of the moisture region exceeds a predetermined reference value (first reference value). 151 can be controlled.

In addition, the controller 180 may control the display unit 151 to execute a touch input applied to the display unit 151 when the area of the moisture region is changed to the predetermined reference value or less.

In an embodiment, when the area of the moisture region is equal to the area of the entire screen 151, the touch input may not be executed since the terminal 100 is in the underwater state.

In another embodiment, when the water is detected in the water but the area of the water region is reduced below the first reference value (eg, when the terminal in the water is taken out of the water), the touch panel is deactivated again. You can switch.

On the other hand, whether the terminal 100 is in or out of the water, whether it is in or out of the water, whether the water drops or flows, it can also be determined by the sensor value.

For example, when the value of the pressure sensor changes rapidly or the signal strength of the entire screen 151 area increases, when the light refraction of the camera lens changes, when a specific sound is input to the microphone, the terminal 100 It can be judged to be underwater (underwater).

As another example, when water enters the earphone port, the impedance is changed. According to this principle, it is possible to determine whether the terminal 100 is in the water by changing the impedance value.

As another example, based on a trend (graph) in which the pressure sensor value changes or a touch pattern (touch pattern generated by moving water) and signal strength detected on the screen 151, the terminal 100 is detected to be out of water. can do.

Referring to FIG. 3, step S310 of detecting at least one sensor value is performed.

As described above, the sensor value includes an electric signal applied to the touch panel of the display unit 151, a touch pattern applied to a continuous touch input, a signal strength of a USB pin, a signal strength of an earphone port, a camera, and the like. It may include a refractive value of the light sensed by the lens, a barometric pressure change value and the like.

Subsequently, a step (S320) of detecting a moisture region in which moisture exists on the display unit 151 is performed based on the sensor value.

Specifically, whether the 'moisture region' exists in the display unit 151 where moisture exists for a predetermined degree or more, and the position and area of the moisture region may be calculated.

In an embodiment, the moisture region may be detected based on the magnitude of the signal strength detected by the USB pin or the magnitude of the detected voltage. In case of C-Type Port among USB ports, it is easy to detect the magnitude of the signal strength or the magnitude of voltage through the Short of VBUS, CC, and SBU Lines to detect the overall moisture region. For example, the CC pin can detect 5.65V (Typ) and the SBU pin can sense 4.4V (Typ) signal strength or voltage level. And, in the case of CC Pin, by detecting the signal strength or voltage level of 3.5V, it can detect whether it is in the water region and whether it is currently in the water.

As another embodiment, the moisture region may be calculated (detected) based on an electrical signal applied to the touch panel of the display unit 151.

Specifically, when moisture is present in the touch panel, a high electrical signal appears due to the conductivity of water. Based on this principle, the controller 180 may calculate a region where the electrical signal is greater than or equal to a predetermined value (for example, a region higher than when the electrical signal is free of a medium, a difference of about 800 degrees) as a moisture region. And based on the coordinate value and area of the area | region whose electric signal is more than predetermined value, the position and area of a water | moisture area can be calculated.

As another embodiment, when a sudden change in water pressure is detected by the water pressure sensor, the moisture region may be detected.

That is, each time the depth of the water deepens by 0.1 meters, the water pressure increases by about 10 hpa. Based on this principle, when the size of the pressure sensor changes rapidly, it can be detected that the underwater state.

Thereafter, a step (S330) of disregarding a signal corresponding to the touch input applied to the moisture region is performed.

In detail, the touch input detected in the moisture region may not be executed. In this case, various functions may be executed according to the size of the moisture region. Specific embodiments related to this will be described later.

Subsequently, when a change in the size of the moisture region is detected, a step (S340) of processing a signal corresponding to the touch input differently is performed based on the changed size.

Hereinafter, a specific embodiment of step S340 will be described with reference to FIG. 4.

Referring to FIG. 4, step S410 is performed in which the calculated area of the moisture region (the size of the changed moisture region) is compared with the preset first reference value.

Accordingly, when the area (size) of the moisture region exceeds the first reference value, the step S420 of setting the touch panel to an inactive state is performed.

Thereafter, a step (S410) of comparing the area of the moisture region with the first reference value is performed.

On the contrary, when the area of the moisture region is equal to or less than the first reference value, setting of the touch panel to the activated state (S430) is performed.

In this case, the procedure is illustrated as being terminated, but is not limited thereto. That is, even after the touch panel is set to the activated or deactivated state, when the area of the moisture region is changed or according to a predetermined period, the step S410 of comparing the area of the moisture region with the first reference value may be performed.

Referring to FIG. 5, when a high signal strength value of a predetermined degree is detected in the entire area of the screen 151, it may be determined that the state is in the water. As another example, the light refraction of the camera lens, the specific sound transmitted to the microphone, it can be determined that the state of the water. In addition, by using the average value transmitted to the pressure sensor according to the depth in the water (a rapid increase in the pressure sensor value), it can be determined that the state in the water.

As another example, when the pressure sensor value which is rapidly increased decreases again, it may be determined that the water is out of the water. Alternatively, when wiping the screen or shaking motion of shaking the terminal 100 is detected, when the signal strength value of the screen 151 is reduced to a predetermined value or less or is changed to a predetermined pattern, it is determined that it is out of water. can do. To this end, a signal value of a touch panel, a grip sensor, and a sensor value of a gyro sensor may be used.

That is, the sensor values may detect whether the terminal 100 is in or outside the water, whether it is in or out of the water.

In addition, as described above, the presence or absence of a moisture region, a position, an area, etc. may be calculated based on the sensor values. Accordingly, when the moisture region is changed to a predetermined pattern, it may be sensed that the touch input is caused by moisture.

In an embodiment, when the terminal 100 comes out of the water, the moisture area that is the same as the entire area of the terminal 100 gradually decreases. In this case, as water flows down the screen 151, the moisture region may be changed to a specific pattern. Based on this, malfunctions can be prevented by detecting the touch input applied as the water flows down and not executing it (by not executing the touch input by moisture).

As described above, a ghost touch due to water droplets is recognized as a touch input, and a malfunction may occur. To prevent this, activate the screen 151 fixing function (keep screen information being output on the screen) or determine whether the moisture region is changed to a predetermined pattern after a predetermined gesture is applied and then change the touch panel to an active state. Can be.

In an embodiment, the controller 180 controls the display unit 151 to execute a touch input applied to the display unit 151 based on a change of the moisture region into a predetermined pattern after a predetermined gesture is applied. Can be controlled.

Referring to FIG. 6, when the area of the moisture region exceeds the first reference value, the touch panel may be set to an inactive state.

In an embodiment, when the touch panel is in a deactivated state, when a wiping or shaking of the terminal 100 is applied, the surface area of the droplet is reduced. That is, the area of the moisture region may be reduced to less than or equal to the first reference value.

At this time, the moisture region may be changed to a specific pattern by the above gesture. For example, by wiping the screen, a pattern in which water droplets move in one direction may be detected, and the area of the moisture region may be reduced. Accordingly, the touch panel in the inactive state can be switched to the active state.

According to the embodiment of FIG. 6, the predetermined gesture and the change pattern of the moisture region may be determined together with (or in addition to) decreasing the area of the moisture region. As a result, it is possible to more accurately detect whether the touch input by the water droplets.

Meanwhile, when the first screen information is changed to the second screen information by the touch input applied to the moisture region, the controller 180 may control the display unit 151 to output the first screen information again. have.

In an embodiment, the controller 180 may control the display unit to output another screen information related to the first screen information together with the first screen information.

Referring to FIG. 7, when the terminal 100 is in the underwater state, the touch panel may be in an inactive state while the camera photographing screen 710 (first screen information) is output.

Thereafter, when the terminal 100 is taken out of the water, the touch panel may be switched to an activated state. In this case, the first screen information 710 may be changed in the order of the second screen information 720 and the third screen information 730 by a touch input by the flowing water.

In this case, a gesture of holding the terminal 100 and a gesture of shaking or wiping the screen 151 may be recognized. In addition, it is possible to detect that the moisture region is changed (moved to one side) to a specific pattern by the gesture, and the moisture region is reduced to a predetermined degree.

Accordingly, it may be determined that the touch input input before the gesture is applied is a touch input by moisture. In addition, the first screen information 710 may be output before the screen is changed by a touch input by moisture.

As another example, along with the first screen information 710, other screen information related to the first screen information 710 may be output.

As a specific example, when the first screen information 710 is a camera photographing screen, the screen area may be divided to simultaneously output a gallery screen, a photo sharing screen, a video shooting screen, and the like to each area.

As another embodiment, when the terminal 100 immediately detects a situation out of the water, the operation of the touch panel may be set to be held for a predetermined time. For example, if the area of the moisture region is reduced to a certain degree, but the terminal 100 is detected as being out of the water, the operation of the touch panel is held for a predetermined time without immediately switching the touch panel to an active state. Can be set.

7 is not limited to the situation in which the terminal 100 is taken out of water.

As an embodiment, if a gesture of shaking or wiping the screen is detected after the state of holding the terminal 100 is detected, the area of the moisture region may be checked again by the signal strength of the touch panel. Accordingly, when the area of the moisture region is reduced (when the moisture region is reduced by a predetermined pattern), the touch panel can be switched to an active state and the screen information prior to the error can be output again.

On the other hand, the controller 180 may control the display unit 151 so that a graphic object for executing a predetermined function is output in an area except the moisture area when the area of the moisture area exceeds a predetermined reference value. have.

In an embodiment, the graphic object for executing the predetermined function may include a graphic object displaying a fingerprint recognition area.

Referring to FIG. 8, a fingerprint recognition area 810 may be output to one area of the screen 151.

In an embodiment, the fingerprint recognition region may be output to the region 820 except for the moisture region. Accordingly, a fingerprint icon, a guide message, etc. indicating the changed fingerprint recognition area 820 may be output. When a fingerprint is input to the changed fingerprint recognition area 820, the locked state may be released through authentication. .

Hereinafter, various embodiments in which a graphic object for executing a predetermined function is output in an area except the moisture area when the area of the moisture area exceeds a predetermined reference value will be described.

As an embodiment, when a button is input only when fingerprint recognition is performed, when moisture is detected in the button area, the button area may be displayed in another area.

Accordingly, the position of the photographing icon may be changed to an area without moisture.

As another example, when the fingerprint can be received only when the fingerprint is recognized in the security lock state, the call reception icon may be output in an area without moisture.

As another example, when moisture is detected during fingerprint authentication in the state of receiving NFC and sound wave signals for payment, the position of the fingerprint recognition region may be changed so that the fingerprint recognition region is output in the region without moisture.

Similarly, when NFC and sound wave signals are received for payment, when drag input is required (such as for selecting a payment means), the drag input area moves to an area where moisture is not detected and is output. Can be.

As another example, when moisture is detected in the fingerprint recognition area, the fingerprint recognition area may be output from a second display in which moisture is not detected among the plurality of first and second displays. In this case, the first display may be a main display of a wide area, and the second display may be a second display of a narrow area.

As a specific example, when moisture is detected in the music control bar area and fingerprint authentication is not performed (in case the fingerprint control bar area can be input after fingerprint authentication), the music control bar area on the second display (second screen) without moisture is present. (Fingerprint authentication area) can be output.

In addition, when moisture is detected in the navigation bar area (home key, etc.) operable after fingerprint authentication, the navigation bar area (fingerprint authentication area) may be output to the second display (second screen) without moisture.

As another example, when the keyboard input is possible only after the fingerprint is recognized, the position requiring the fingerprint recognition may be moved and displayed on the keyboard area when moisture is detected. Specifically, when the fingerprint is authenticated to the notification icon area, the detailed notification content may be output. Subsequently, when moisture is detected in the keyboard region in which the fingerprint is output, the keyboard may be output in the region without moisture. In this case, the keyboard may be separated and output according to the position of the moisture region.

As another example, when notification can be confirmed by fingerprint recognition, the notification message may be output in an area without moisture.

Meanwhile, the controller 180 may activate the voice recognition mode when the area of the moisture region exceeds a predetermined reference value and a preset additional condition is satisfied.

Referring to FIG. 9, when a touch operation is difficult as water droplets continuously form on the screen 151, the voice recognition mode may be activated. Accordingly, the object 900 indicating that the voice is input may be output.

As another example, when a motion of tilting the terminal 100 toward the face is detected, the voice recognition mode may be activated.

As a specific example, when a sensor value recognized as a grip is sensed by the grip sensor, motion data indicating an inclination state of the terminal 100 in the gyro sensor and an acceleration value moving in the direction of the microphone are detected, by a microphone or more. When the voice decibel increases, when the signal strength indicating the out of water is detected on the touch panel, when the user's face recognized by the front camera is not recognized (when all the above conditions are satisfied), The recognition mode can be activated.

Meanwhile, the controller 180 may control the display unit 151 to change the output state of the graphic object output to the display unit 151 when the area of the moisture region exceeds a predetermined reference value. .

Referring to FIG. 10, when the area of the moisture area exceeds a predetermined reference value, the size and thickness of the text being output may be changed.

For example, when the area of the moisture region exceeds a predetermined reference value, the size and thickness of the text may increase. As another example, the size of an image or an icon may be enlarged and displayed.

The controller 180 may control the display unit 151 to output a graphic object for replacing a predetermined touch input when the area of the moisture region exceeds a predetermined reference value.

In an embodiment, when a touch input is applied to the graphic object, the controller 180 may control the display unit 151 to execute the predetermined touch input.

When moisture is present on the screen 151, a sliding phenomenon occurs when a swipe or drag input is generated, and the corresponding gesture may not be executed. Accordingly, a graphic object (Floating Navigator) that may complement the gesture may be output.

Referring to FIG. 11, the gallery application may apply left and right swipe inputs to change an output image.

In this case, when the area of the moisture area exceeds a predetermined reference value, an icon 1100 for replacing the left and right swipe input may be output. When a touch input is applied to the icon 1100, an image before or after the current state may be output.

Hereinafter, a further embodiment related to FIG. 11 will be described.

As an embodiment, when a screen capable of turning a page to a previous or subsequent step such as a home screen is being output, when an area of the moisture area exceeds a predetermined reference value, an icon for replacing a left and right swipe input may be output. Can be. Accordingly, when a touch input is applied to the icon, a page before or after the current state may be output.

As another embodiment, when there is moisture on the screen, it is difficult to zoom in or zoom out through a swipe. Accordingly, when there is moisture on the screen, the touch-in or zoom-out may be set by double touch input.

Meanwhile, the controller 180 may control the display unit 151 to differently output screen information for unlocking according to a result of comparing the area of the moisture region with a predetermined reference value in the locked state. .

Referring to FIG. 12, it may be detected that the area of the moisture region is less than or equal to a predetermined reference value and the moisture region is added at a predetermined period.

As an embodiment, when the area recognized as a water drop on the screen 151 is less than a predetermined reference value, and the period of falling water drops is long, the existing pattern lock screen may be automatically switched to a lock release screen suitable for a moisture environment.

As a specific example, as moisture is sensed while the general pattern lock screen 1210 is output, an image screen 1220 indicating a moisture detection state may be output. The image screen 1220 may display a graphic object in which the water droplets move (fall) according to the amount of water droplets detected. Alternatively, the amount of water droplets detected may be expressed as a frequency of falling water drops, or a frequency of waves.

In addition, a plurality of touch box regions 1230 indicating a pattern touch point (a vertex included in the pattern input) corresponding to the pattern input may be output. The plurality of touch box regions 1230 may be variably displayed according to the position and area of the moisture region.

Accordingly, when the touch input is applied to the touch box region 1230 in the drag order for the pattern input instead of the pattern input for unlocking, the touch input may be unlocked.

For example, instead of a drag input in the first direction 1240, which is a pattern input, the first touch box region 1230-1 may be touched and then the second touch box region 1230-2 may be touched.

Hereinafter, an embodiment in which different lock screens are output according to the position, area, and period in which moisture is detected on the screen 151 will be further described.

As an embodiment, if water is on the hand or a certain amount of moisture is present on the screen, and fingerprints are difficult to be learned, screen information for releasing the lock screen may be output by a PIN input.
