According to an embodiment of the present invention, the controller may adjust the emission time of the light of the second intensity and the second intensity based on information of the skin color set in a specific manner. Accordingly, a more accurate pressure value can be calculated according to the amount of light suitable for each user having various skin colors.

In one embodiment of the present invention, when the watch-type terminal is determined to be in an unsealed state, the control unit may form the control command based on a touch input of a specific type applied on the display unit. Accordingly, the user can perform a desired function even when the watch-type terminal is not worn.

According to the present invention, substantially the same sensor is used to detect whether the watch-type terminal is worn and to form a control command by pressure change, so that additional electronic parts for performing different functions are unnecessary. Therefore, the components of the watch-type terminal can be minimized, and the thickness of the terminal can be minimized.

Further, since the intensity of the light and the output time of the light are determined according to the skin color of the user's body, accurate measurement can be performed according to the amount of light received even when the skin color of the wearer changes.

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.

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 can be determined according to the operating state of the current watch type 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 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 arranged to scan the motion of the object to be sensed 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 window 151a of the display unit 151 may be mounted on the first case 101a to form a front surface of the terminal body together with the first case 101a.

The main body 101 may include an audio output unit 152, a camera 121, a microphone 122, a user input unit 123, and the like. When the display unit 151 is implemented as a touch screen, the display unit 151 may function as a user input unit 123, so that the main unit 101 may not have a separate key.

The band 300 is worn on the wrist so as to surround the wrist, and may be formed of a flexible material for easy wearing. As an example, the band 300 may be formed of leather, rubber, silicone, synthetic resin, or the like. In addition, the band 300 may be detachably attached to the main body 101, and may be configured to be replaceable by various types of bands according to the user's preference.

On the other hand, the band 300 can be used to expand 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 300 may be provided with a fastener 330. The fastener 300 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 330 is implemented as a buckle is shown.

3 is a conceptual diagram illustrating a control method of a watch-type terminal according to an embodiment of the present invention. 4A to 4E are conceptual diagrams for explaining the control principle of the watch-type terminal of FIG.

Referring to FIG. 4A, the sensor unit 400 is disposed adjacent to one surface of the terminal body. The display unit 151 is disposed on a surface opposite to the one surface, and the window 151a is disposed on the display unit 151 to provide an appearance. The display unit 151 and the sensor unit 400 are formed on different surfaces of the watch-type terminal 100.

A plurality of electronic components such as a power supply unit 190 and a circuit board 181 'may be mounted between the display unit 151 and the sensor unit 400. When the watch-type terminal 100 is worn on the user's wrist, the window 151a is exposed to the outside and the sensor unit 400 is disposed to face the wrist of the user. The sensor unit 400 may be mounted movably within the body 101. Accordingly, when pressure is applied to the display unit 151, the sensor unit 400 or the terminal body 101 can be moved in close contact with the skin.

The sensor unit 400 includes a light emitting unit 410 that emits light to the outside and a light receiving unit 420 that senses when the emitted light is reflected by a part of the user's body . The number of the light emitting unit 410 and the light receiving unit 420 is not limited.

Referring to FIG. 4C, the light emitting unit 410 may include at least one of an LED that emits light of a specific color and an IR LED that emits infrared light. Visible light can penetrate deep into the skin as the wavelength gets longer. Green light with a relatively short wavelength penetrates only into the epithelium of the skin, while red light with a long wavelength penetrates into the dermis of the skin. Infrared light with longer wavelengths than visible light penetrates enough to reach the skin's hips.

The light emitting unit 410 emits light of a first intensity (S210). The intensity of the light emitted by the light emitting unit 410 may be substantially proportional to the output current value. Here, the light may correspond to a green light and / or an infrared light. The light emitting unit 410 emits light of a first intensity at specific time intervals. The control unit 180 determines whether the watch-type terminal 100 is worn on the wrist (or part of the user's body) based on the first-intensity light sensed by the light-receiving unit 420 S220).

When the watch-type terminal 100 is worn on the wrist, at least a part of the light of the first intensity is reflected by the user's body (skin). When the reflected light is incident on the light receiving unit 420, the controller 180 determines that the watch-type terminal 100 is worn on the user's body. On the other hand, if no light is incident on the light-receiving unit 420, it is determined that the watch-type terminal 100 is not worn.

Referring to FIG. 4D, the light emitting unit 410 emits light of a first intensity q1 in a first period T1. The light of the first intensity q1 may be emitted for a first time t1. The light of the first intensity q1 may correspond to green light and / or infrared light. The controller 180 may execute a specific function based on whether or not the watch-type terminal 100 is worn.

The controller 180 controls the light emitting unit 410 to output light of a first intensity q1 (S230). When the control unit 180 determines that the wristwatch is in the worn state after the output of the first intensity light, the control unit 180 controls to output the light of the second intensity, 1 and second intensity light can be output regularly.

Referring again to FIG. 4D, the light of the second intensity q2 is output at a time while the output of the light of the first intensity q1 is blocked. The second intensity q2 is set to a different magnitude from the first magnitude q1 and the light of the second magnitude q2 is output for a second time t2 in a second predetermined period T2 .

The second time t2 may be set to be shorter than the first time t1 and the second intensity q2 may be set to be smaller than the first intensity q1. When the time for outputting the light of the second intensity q2 and the second intensity q2 is equal to or greater than a specific reference, a change (increase) in the amount of light sensed may not occur as the pressure increases. That is, even if the pressure applied when the second intensity q2 and the second time t2 are equal to or higher than the specific reference is changed, substantially the same amount of light is detected by the light receiving unit, Can not. Accordingly, in general, it is preferable that the second intensity q2 is smaller than the first intensity q1 and the second time t2 is set shorter than the first time t1. However, the second intensity q2 and the second time t2 can be changed according to the skin color of the wearer wearing the watch-type terminal 100 according to an embodiment of the present invention, Will be described in detail.

The light of the second intensity q2 and the light of the first intensity q1 are preferably alternately output and the output period is preferably set substantially the same. The light of the second intensity (q1) may correspond to green light or infrared light.

On the other hand, the infrared light is not detected by the naked eye while being output, and penetrates into the dermis or epithelium of the skin. In contrast, when the green light is output (blinking) at a specific time interval, the light is sensed by the naked eye. Therefore, when a clearance is generated between the light emitting part 410 and the skin or when the watch- There is a disadvantage that light flicker is detected. Also, the green light may be affected by the pulse wave of the skin epithelium or the noise due to the heartbeat when the light reaches only the skin epithelium and is reflected and sensed by the light receiving unit. Therefore, when the light of the second intensity is realized by the green light, an error may occur in calculating the pressure value according to the amount of received light.

Accordingly, it is preferable that the light of the second intensity q2 outputted at a specific time interval to calculate the pressure value is realized by infrared light.

The first intensity q1 may be about 50 mA, the second intensity q2 may be about 30 mA, the first time t1 may be about 7.5 μs, and the second time t2 may be about 4 μs, The numerical values are not limited thereto and can be changed based on the setting of the user.

The control unit 180 calculates a pressure value based on the amount of the reflected light detected by the light receiving unit 420 in step S240 and performs a specific function according to the pressure value in step S250. The pressure may be applied on the display unit 151. [ The touch sensor included in the display unit 151 can sense the touch while the pressure is applied and the control unit can perform a specific function using the touch position and the pressure value applied on the display unit 151 have.

Referring to FIG. 4B, the light output toward the skin is reflected from the skin and is incident on the light-receiving unit. When the pressure F is externally applied, the watch-type terminal 100 or the sensor unit 400 moves and the light emitting unit 410 and the light receiving unit 420 are brought into close contact with the user's skin. As the light emitting part 410 and the light receiving part 420 approach the skin, the amount of light received increases.

When only the light of the first intensity q1 is output, substantially the same amount of light is received regardless of the degree that the light emitting unit 410 and the light receiving unit 420 are brought into close contact with the skin. Therefore, when only the light of the first intensity q1 is emitted, the pressure applied to the display unit 151 is not sensed. However, if the distance between the sensor unit 400 and the skin changes due to an external force while the light of the second intensity q2 is output, the amount of light received varies and the change of the pressure value can be measured.

Referring to FIG. 4E, the control unit 180 determines the magnitude of the pressure according to the amount of light incident by the light receiving unit 420 (S420). The controller 180 distinguishes the pressure touch from the general touch based on a specific reference light amount. Here, the pressure touch corresponds to a case where a pressure equal to or higher than a specific reference value is applied on the display unit 151 while being touched on the display unit 151, and the general touch corresponds to a touch on the display unit 151 When a pressure lower than a specific reference is applied on the display unit 151. [

FIG. 4E is a graph showing changes in the amount of infrared light received while pressure is applied to the display unit 151. FIG. While the pressure touch is applied and released, the amount of light incident on the light receiving portion increases and then decreases again.

If the amount of received light measured while the first light receiving amount and the pressure are applied / canceled is equal to or greater than the first reference value (for example, about 30000 mA), the controller 180 determines that the light receiving amount is a pressure touch, If it is less than or equal to the reference value (for example, about 2500 mA), it can be determined by a general touch. The first and second reference values may be set differently, and may be changed by the user.

According to the present embodiment, substantially the same sensor is utilized for detecting whether or not the watch-type terminal is worn and forming a control command by the pressure change. That is, since the pressure applied by the user is measured by using a sensor for detecting whether or not the sensor is worn, an additional sensor unit for performing different functions and a control device for calculating the pressure value are unnecessary. Therefore, since the internal space for mounting the additional sensor unit and the control unit is unnecessary, the thickness can be minimized and the unit cost of the mobile terminal can be reduced.

The light emitted from the light emitting unit 410 may be reflected or absorbed based on the state of the skin on which the light is incident. In particular, the amount of light incident on the light receiving unit 420 may vary depending on the color of the skin. Hereinafter, a control method of adjusting the intensity (current value) of light output according to the skin color in order to increase the accuracy of the pressure value measurement will be described.

FIG. 5A is a conceptual view for explaining a control method of controlling the amount of light emission based on the skin color according to an embodiment of the present invention, FIG. 5B is a view illustrating a control method of controlling the emission amount of light based on the amount of received light. And Fig.

5A illustrates the emission of light in a state where the watch-type terminal 100 is worn on the wrist of the first skin A. FIG. 5A illustrates a state in which the watch- 5A illustrates the emission of light in a state where the watch-type terminal 100 is worn on the wrist of the third skin C and FIG. do.

The first to third skin A, B, and C have different colors so that the reflectance and the absorption rate of light are different from each other. The colors of the first and second skin A and B of the third skin C And the second skin B is higher in absorption amount than the first skin A. For example, The darker the skin color, the greater the absorption.

Referring to FIG. 5A, the light emitting unit 410 may emit light of a first intensity q1 at a first interval T1 and light of a second intensity q2 at a second interval T2. Output light. The second intensity q2 may be set to be smaller than the first intensity q1. The light of the first intensity q1 and the light of the second intensity q2 are alternately outputted. The light of the first intensity q1 is outputted during the first time t1 and the light of the second intensity q2 is outputted during the second time t2.

Referring to FIG. 5A, the light emitting unit 410 outputs light of a first intensity q1 for a first time t1 at a first interval T1 and a light of a second intensity q2 for a first time t1, And outputs light for a third time (t3) at a second interval (T2). That is, when the absorption amount of the skin decreases, the controller 180 increases the time for outputting the light of the second intensity q2 to secure the reflected light. For example, the second time t2 may correspond to about 4 μs, and the third time t3 may correspond to about 7 μs.

Referring to (c) of FIG. 5, the light emitting unit 420 may output light of a third intensity q3 during a third time t3. The third time t3 is set to be larger than the second time t2. For example, when the second intensity q2 is about 4 mA, the third intensity q3 may correspond to about 7 mA.

 The controller 180 may increase the intensity of the light and the output time based on the degree of reflection of the light due to skin color. The intensity and output time of the light can be independently increased or decreased or changed together.

The control unit 180 controls the light emitting unit 420 to increase the intensity of the output light as the skin color of the light is increased. The light of the first intensity q1 is output during the first time t1 and the light of the second intensity q2 is output during the second time t2. That is, the controller 180 outputs infrared light with a larger current as the skin color of the light is reflected and the amount of reflection is smaller.

Accordingly, the applied minimum pressure and the maximum pressure can be calculated based on the amount of light reflected on the light receiving unit. The watch-type terminal 100 may output light based on the intensity and the time set by the user's selection among a predetermined plurality of reference light quantities.

Referring to FIG. 5B, a control step of adjusting the intensity and output time of light for calculating the pressure value will be described. The controller 180 outputs the reference light amount for a reference time (S310). The controller 180 compares the amount of light incident on the light receiving unit 420 with a reference light amount range (S320). Herein, the reference light amount range includes a minimum light amount and a maximum light amount that vary in the amount of light incident on the light-receiving unit depending on the external force so as to be able to sense the pressure applied by the user.

If the amount of light incident on the light receiving unit 420 is between the minimum light amount and the maximum light amount in step S350, the controller 180 outputs light having a predetermined intensity in step S360.

On the other hand, when the amount of incident light is smaller than the minimum amount of light (S331), the light reflected by the skin is too small to detect a change in light amount due to the pressure change. The controller 180 increases the output time of the light of the reference intensity (S332).

The control unit 180 compares the reference light amount with the incident light amount after increasing the output time and if the incident light amount is still smaller than the minimum light amount at step S333, (S334). The control unit 180 compares the incident light amount and the minimum light amount while increasing the intensity of the light. If the incident light amount is equal to or greater than the minimum light amount and the incident light amount is less than the maximum light amount, the control unit 180 outputs the light of the changed intensity at a specific time interval at step S360.

If the amount of incident light is greater than the maximum amount of light (S341), the controller 180 may not detect a change in the amount of light even if the applied pressure changes due to too much light reflected by the skin. In this case, the controller 180 decreases the output time for outputting the light of the reference intensity (S342).

The control unit 180 compares the reference light amount with the incident light amount after reducing the output time and if the incident light amount is still larger than the maximum light amount at step S343, ). The controller 180 compares the incident light amount and the maximum light amount while reducing the intensity of the light. If the incident light amount is less than or equal to the maximum light amount and the incident light amount is greater than the minimum light amount, the control unit 180 outputs the light of the changed intensity at a specific time interval at step S360.

According to the present embodiment, since the mobile terminal determines the intensity of light and the output time of light by using data obtained by directly reflecting light on the wearable body of the watch-type terminal 100, It is possible to determine the intensity of light and the output time at which a step is unnecessary and the pressure can be measured more accurately.

FIG. 6A is a flowchart for explaining a control method of controlling intensity of light output based on applied pressure, and FIG. 6B is a conceptual diagram illustrating a control method of FIG. 6A.

The control unit 180 detects the wearing of the watch-type terminal 100 by the light incident on the light-receiving unit 420 (S311). When it is determined that the watch-type terminal 100 is worn on the user's body (wrist), the pressure applied to the terminal body 101 is received (S371). In this case, the display unit 151 may output guide information for guiding pressure to be greeted.

Referring to FIG. 6B, the display unit 151 outputs a first guide image 501a for guiding application of a touch, which is a minimum pressure. The controller 180 measures the amount of light sensed through the light receiving unit 420 while the touch is applied. The display unit 151 outputs a second guide image 501b for applying a maximum pressure.

The control unit 180 measures the amount of light sensed by the light receiving unit 420 while the maximum pressure is applied and the control unit 180 compares the light receiving amount when the minimum pressure and the maximum pressure are applied (S372 ). Also, when the applied pressure is discriminated by a plurality of discontinuous values, it is possible to grasp a change in the amount of received light while applying the maximum pressure from the lowest pressure.

The controller 180 adjusts the output times of the second intensity and the second intensity light based on the difference of the received light amounts (S373).

According to the present embodiment, it is possible to determine the intensity of light and the output time that are optimized to distinguish the intensity of the pressure applied by the user, so that the sensor unit can be controlled to suit the power or habit of the individual using the watch- can do.

Referring to FIG. 6C, a control method of adjusting the intensity of light suitable for a user's skin color will be described. According to the present embodiment, the memory 170 stores a plurality of reference information corresponding to reflectances of different skin colors. Here, the reference information includes information on the intensity of light, the output time, and the output interval for sensing the pressure. The memory 170 stores an image representing skin color together with the reference information.

The display unit 151 outputs a first image 502a of a plurality of images when it is detected that the watch-type terminal 100 is worn on the user's wrist. The first image 502a may correspond to an image corresponding to the selected reference information when the Waggon-type terminal 100 is worn by the user, or may correspond to a reference image.

The first image 502a indicates a skin color and may not include specific information. The first image 502a may represent the brightest or darkest skin color, or may correspond to an image corresponding to a previously applied skin color. The memory 170 may store user information distinguished from the reference information and the reference image. Although not shown in the figure, the control unit may control the light emitting unit 410 so that light is output as reference information corresponding to the input user information.

The control unit 180 may sequentially output the second image 502b and the third image 502c based on the touch applied to the first image 502a. The first through third images 502a, 502b, and 502c correspond to different reference information. Here, the touch may correspond to a dragging-type touch input applied in a specific direction.

The control unit 180 controls the light emitting unit 410 based on reference information corresponding to the third image 502c selected based on the touch applied to the icon on the display unit 151. [ When the image is selected, the control unit 180 controls the light emitting unit 410 to emit light based on the reference information, and measures the pressure value by the light sensed through the light receiving unit 420.

The display unit 151 outputs the initial screen 500 when the third image 502c is selected and the light emitting unit 410 is controlled accordingly. The initial screen 500 may correspond to a homsscreen page that represents time, includes information about an event, or includes information (icons) of a specific application. However, It can be changed accordingly.

According to the present embodiment, the user selects an image most similar to the skin color in a state wearing the watch-type terminal 100, and determines a sensing condition optimized for the skin color (intensity of light for detecting a pressure change, Output interval) can be set, so that a suitable control method based on the applied pressure change can be implemented.

7A and 7B are conceptual diagrams illustrating a pressure control method according to one embodiment of the present invention.

Referring to FIG. 7A, the controller 180 distinguishes the pressure of a touch applied to the same graphic image displayed on the display unit 151 and performs different functions. For example, the display unit 151 outputs an event notification image 610 indicating the occurrence of an event on an initial screen including numeric information for indicating the time, and the event notification image 610 includes one It can be displayed on a number.

The control unit 180 controls the display unit 151 to output icons 611 of different applications including notification information of an event when a pressure touch is applied to the event notification image 610. [ The icons 611 may be displayed on different numbers. The controller 180 may output the icons 611 in an expanded state from the event notification image 610 when the pressure value of the pressure touch is detected to be equal to or greater than a specific reference range.

Although the pressure value on the drawing is shown as the pressure of the first stage of the four stages, the pressure value for outputting the icons 611 is not limited thereto.

Although not specifically shown in the figure, it is possible to output more icons in the order of the latest received event based on the change amount of the pressure value. That is, as the sensed pressure increases, the number of output icons may increase.

In addition, the controller 180 may control the display unit 151 so that the icons 611 disappear when a pressure touch of substantially the same pressure is applied on the event notification image 610. [

When the general touch is applied to the event notification image 610, the controller 180 outputs a first notification screen 621 corresponding to the first or most recently received event . In this case, the controller 180 controls the display unit 151 to output a second notification screen 622 corresponding to another event when a dragging-type touch input is applied on the first notification screen 621 do.

According to the present embodiment, it is possible to provide different types of time information including information related to an event based on a touch, which is applied at different pressures to icons corresponding to received (generated) events. Accordingly, the user can receive information on the event in a desired manner by applying different touches.

Referring to FIG. 7B, the display unit 151 outputs a home screen page 612 including a plurality of icons. The control unit 180 outputs an execution screen 623 corresponding to the icon selected based on the touches applied to the plurality of icons. The plurality of icons may be displayed on a number indicating the time.

On the other hand, the control unit 180 may output at least one graphic image which is applied to one of the plurality of icons and can directly execute the function of the selected application based on the pressure touch having a pressure value equal to or higher than the reference pressure . For example, if the selected icon is related to the call function, it may output at least one contact information for executing the call function based on the pressure touch. Although not shown in the figure, the controller 180 may control the display unit 151 to output other information related to the call function based on the pressure touch having another pressure value. The controller 180 may send a call to the contact based on the touch information.

According to the present embodiment, the user can sequentially grasp the detailed information included in the specific image by using the pressure touch, and the user can perform different functions according to the touch method.

8A to 8D are conceptual diagrams for explaining a control method of outputting different information according to a pressure value.

Referring to FIG. 8A, the controller 180 outputs an icon 613 corresponding to a specific application. The icon 613 may be output to one area of the display unit 151 to notify the reception of an event when an event related to the application is received.

Referring to FIG. 8A, when the pressure value of the pressure touch corresponds to the first pressure, the controller 180 outputs detailed information 625a related to the event. For example, the pressure value may correspond to a maximum pressure. The detailed information 625a may include, but is not limited to, the contents of an event, the time at which the event was received, the source of the event, information about the external device to which the event was sent, and the like.

Referring to (c) of FIG. 8, the controller 180 controls the display unit to output the minimum information 625c of the application when a pressure touch due to the lowest pressure is not received. The minimum information 625c may include, but is not limited to, the number of received events and information associated with the application. However, most of the information included in the minimum information 625c may be included in the detailed information 625a.

Referring to FIG. 8 (b), the controller 180 controls the display unit 151 to output the basic information 625b of the event when a pressure touch corresponding to the intermediate pressure is applied. The basic information 625b may include information of an external device that transmitted an event, the number of received events, application information, and the like.

The control unit 180 may control the display unit 151 to output the basic information 625b and the detailed information 625a by applying an additional pressure touch in a state in which the minimum information 625c is output.

According to the present embodiment, since information of the same event is provided in sequential amounts based on the pressure touch applied to the watch-type terminal, the user can receive as much information as desired by applying pressure. In addition, the user can be provided with desired information about the event without executing the application.

Referring to FIG. 8B, the controller 180 may omit a plurality of control steps for performing a predetermined function based on the pressure touch, and may immediately execute the function. The display unit 151 outputs a purchase screen 630 when an application for purchasing a product is running. The purchase screen 630 may include a graphic image 631 for proceeding with the purchase.

When the pressure touch having a specific pressure value is applied to the graphic image 631, the control unit 180 outputs the approval screen 630 directly.

On the other hand, the controller 180 controls the display unit 632 to output a purchase idle screen 632 when a general touch is applied to the graphic image 631. The purchase waiting screen 632 may include an indicator that waits for a control command according to a purchase intention of the user for a specific time and changes with the passage of time.

The controller 180 may again output a purchase screen 630 including a graphic image for confirming the purchase when the specific time has elapsed. If a pressure touch including a pressure value is applied, the process is controlled so as to perform the step of waiting for purchase for a specific time when the normal touch is applied, if the process goes to the approval step without waiting for the purchase.

According to the present embodiment, in order to clarify whether or not a touch applied on the display unit corresponds to a control command by a purchasing intention when performing a purchasing function in which a decision on user's consumption should be made, When the pressure is sensed, the purchasing function is executed. On the other hand, if the general touch (that is, when a touch having a pressure value equal to or higher than the reference is applied) is applied, a step of confirming the purchase intention again is performed. Accordingly, it is possible to prevent the concern of applying the control command of purchasing in private or inadvertent.

Referring to FIG. 8C, the controller 180 provides different related information based on the pressure touch having different pressure values. The display unit 151 outputs a purchase screen 630 for a specific item.

When the pressure touch having the first pressure value is applied, the controller 180 outputs the purchase screen 633. When the pressure touch having the second pressure value smaller than the first pressure value is applied, And controls the display unit 151 to output detailed information of the display unit 151. [ For example, the detail information 634 may include graphical images that allow the user to select details for purchase prior to the purchase screen 633.

The control unit 180 controls the display unit to sequentially output the detailed information 634 and the purchase screen 633 according to the pressure value of the pressure touch.

According to the embodiments, the user can omit a plurality of steps for executing one function based on the pressure value of the pressure touch, so that the user can execute the desired function more quickly.

Referring to Fig. 8D, a control method of changing the classification standard of information based on the pressure value will be described. The display unit 151 outputs screen information 670 including a plurality of pieces of information. The controller 180 arranges and provides the plurality of pieces of information based on criteria set by the user. The plurality of pieces of information may correspond to information about goods of the online shopping mall.

The control unit 180 controls the display unit 151 to output a first alignment screen 671 in which the information is aligned with a first reference when the pressure touch having the first pressure value is applied, And controls the display unit 151 to output a second alignment screen 672 in which the information is aligned with a second reference when a touch having a pressure value is applied.

Here, the first and second different criteria may correspond to a title, price (lowest price, closing price), creditworthiness of the seller, sales volume, and the like. According to the present embodiment, it is possible to efficiently provide information aligned with a user's desired reference in a watch-type mobile terminal having a small display area. The pressure touch having different pressure values can be applied continuously or discontinuously even with the alignment screen being output.

9A and 9B are conceptual diagrams for explaining a control method according to a pressure value according to another embodiment.

Referring to FIG. 9A, the display unit 151 outputs an icon 614 of an application executing a specific function. The control unit 180 ignores the touch and blocks the execution of the specific function when a general touch equal to or lower than a specific pressure value or a pressure touch having a pressure value equal to or lower than the reference pressure value is applied. For example, the specific function may correspond to important functions that the user intends to control, such as making a call to an external device, changing a notification mode, and the like.

The controller 180 immediately executes a corresponding function when a pressure touch having a predetermined pressure value or more is applied.

According to the present embodiment, when an unintended touch is applied to the display unit, it is possible to prevent the function from being executed against the will of the user.

An authentication method using the pressure touch will be described with reference to FIG. 9B. When the watch-type terminal is in the lock mode, the controller 180 performs authentication and cancels the lock mode based on a touch applied to a predetermined area on the display unit.

The authentication information for canceling the lock mode may correspond to at least one specific area on the display unit and a pressure value corresponding to the specific area. When the touch having the pressure value is applied on the lock screen 650, the controller 180 may output an image having a different shape corresponding to the pressure value.

According to the present embodiment, the user can set the authentication information including the pressure touch F and the general touch N, thereby improving the security.

10A to 10D are conceptual diagrams for explaining a method of controlling a function related to the pressure touch when the watch-type terminal is not worn.

4B, when the light emitting unit and the light receiving unit are not adjacent to one area of the body, the light can not be reflected by the watch-type terminal according to the present embodiment. A control method of the watch-type terminal 100 in a non-worn state, which is a function of being controlled by a pressure touch applied when the watch-type terminal 100 is worn on the body, will be described.

Referring to (a) of FIG. 10, the display unit 151 outputs an execution screen 660 of a message application. The execution screen 660 includes received and transmitted dialog information 661. [ The controller 180 controls the display unit 151 to output a function screen 662 for performing a function related to the dialog information 661 when a pressure touch having a specific pressure value is applied to the dialog information 661 ).

Here, the function screen 662 includes graphic images corresponding to at least one function using the dialog information 661. For example, it is possible to output the detailed information of the external device that has sent the conversation information 661, the reply function corresponding to the conversation information 661, the transmission of the location information to the other party of the conversation information 661, have.

Referring to FIG. 10A, when the watch-type terminal 100 is not worn, there is no light incident on the light receiving unit 420, and thus the pressure value can not be measured. Therefore, even if the user applies pressure on the display unit 151, the specific function is not executed.

The control unit 180 controls the display unit to output the function screen 662 when a long touch is applied to the dialog information 661 for a specific time (t, several seconds) or longer. That is, when the sensor unit 400 senses that the watch-type terminal 100 is not worn by the sensor unit 400, the controller 180 determines that the touch input having the specific pressure value corresponds to the long- , And executes a predetermined function.

Accordingly, the user can execute the feature function that has been executed in the worn state by using another method, even when the watch-type terminal 100 is not worn.

10B, when the watch-type terminal 100 is sensed to be worn on the wrist, the controller 180 applies the approval icon on the approval screen 635, Performs the payment function based on the pressure touch, and controls the display unit to output the payment completion screen 635a.

The controller 180 may implement the specific pressure value as the user authentication information, and perform a payment function without a separate authentication procedure when the pressure touch is applied.

10B, when the controller unit 180 determines that the watch-type terminal 100 is not worn by the sensor unit 400, the control unit 180 determines that the watch- The above-mentioned payment function is not performed. The control unit 180 outputs an authentication screen 651 when a general touch is applied to the approval icon. The authentication screen 651 may correspond to touch information applied to a specific area, or may include fingerprint information of a user, text information, and the like.

When the authentication process is completed according to the authentication information, the control unit 180 executes a payment function and outputs a payment completion screen 635a.

According to the present embodiment, when the user's intention is controlled by the pressure touch with respect to important functions, the accuracy of performing the functions can be improved through additional steps in the state where the watch-type terminal is not worn.

Referring to FIG. 10C, when there is a control image for receiving a pressure touch such that a specific function is performed by a pressure touch having a specific pressure value, the control unit 180 controls the touch- Explain.

The control unit 180 outputs an indicator 701 when the watch type terminal 100 is switched to an unused state when the execution screen 660 for a specific application is output.

The indicator 701 is displayed in a region corresponding to the position of the sensor unit 400 including the light emitting unit 410 and the light receiving unit 420. [ The indicator 701 indicates a region where a user must touch a back of the terminal body with a finger or a part of the body. The control unit 180 may output the indicator 701 when the watch-type terminal 100 is not worn, and the function is performed based on the pressure touch. When the watch-type terminal 100 is switched from the wear state to the wear-out state, the indicator can be output and disappear only for a specific time period.

The controller 180 can perform a specific function based on the pressure touch sensed after the finger or the like is contacted to the sensor unit 400 in a state in which the indicator 701 is output. In Fig. 10C, a function screen 622 is output based on the pressure touch applied to the dialog information 661.

The control unit 180 may be configured to detect a pressure value when a finger or the like comes into contact with the sensor unit 400 and the light reflected by the skin reaches the light receiving unit 420 It is possible to modify the shape of the indicator 701 or to control the display unit 701 so that the indicator 701 disappears.

According to the present embodiment, it is possible to control using the pressure touch even when the watch-type terminal is not worn, and the user can recognize the function control based on the pressure touch through the indicator and perform the body contact for the pressure touch.

Referring to FIG. 10D, when the watch unit 100 is sensed to be worn, the control unit 180 controls the display unit 151 to display the notification screen 621 ' And receives a pressure touch. The control unit 180 controls the display unit 151 to output the first notification screen 621 based on the pressure touch having a specific pressure value.

Referring to FIG. 10D, when the watch-type terminal 100 is detected as not wearing, the controller 180 displays the alarm screen 621 'output on the display 151, The user can not receive the pressure touch applied to the touch panel. In this case, the control unit 180 controls the display unit 151 to output an authentication screen 702 when a general touch is applied to the alarm screen 621 '.

That is, the control unit 180 can control the function controlled by the pressure touch when worn, based on the authentication information 702 when not worn.

11 is a conceptual diagram for explaining a control method using a pressure touch according to another embodiment.

Referring to FIG. 11, the display unit 151 outputs an execution screen 626 including a first graphic image 626a and a second graphic image 626b. For example, the execution screen 626 may correspond to the detailed information of one contact information Tom stored in the memory 170. The first graphic image 626a is an icon for transmitting a call to the contact information and the second graphic image 626b may correspond to an icon for outputting additional information.

Referring to FIG. 11A, when the touch sensed as less than a predetermined reference pressure, that is, general touch, is applied to the first graphic image 626a, the controller 180 displays the first graphic image 626a on the first graphic image 626a The execution of the corresponding function is blocked. The controller 180 ignores general touches applied on the first graphic image 626a.

Meanwhile, the control unit 180 controls the display unit to output additional information 627 to the second graphic image 626b when a touch sensed below the pressure, that is, a general touch, is applied to the specific graphic unit 626b.

11B, when a pressure touch having a pressure value equal to or higher than a specific reference pressure is applied to the first graphic image 626a, the controller 180 controls the first graphic image 626a, As shown in Fig. For example, the control unit 180 can originate a call using the contact information. Accordingly, the display unit 151 can control the display unit 151 to output a call origination screen 628. [

Although not shown in the drawing, the controller 180 may perform a function corresponding to the second graphic image 626b even when a pressure touch is applied to the second graphic image 626b .

According to the present embodiment, it is possible to set the function to be executed only when a pressure to be applied by the user is applied, in the case of a function that the user intends to execute. This makes it possible to prevent the execution of the function against the user's intention by the touch.

12A to 12C are conceptual diagrams for explaining a control method using a pressure touch applied to an initial screen. The initial screen includes a number indicating time, an hour hand 503a, a minute hand 503b, and a center point 503c. The control unit 180 controls the display unit 151 to modify the time information based on the touch applied to the initial screen or change the design of the initial screen.

Referring to FIG. 12A, the controller 180 may display a notification icon 612a indicating the received event on the number of the initial screen based on the pressure touch applied to the hour hand 503a.

Referring to FIG. 12B, the controller 180 may display a schedule stored in the memory 170 on the initial screen based on the pressure touch applied to the minute hand 503b.

12C, the controller 180 controls the display unit 624 to output a setting screen 624 for changing the driving setting of the watch-type terminal 100, based on the pressure touch applied to the center point 503c, (151). The setting screen 624 includes an image for controlling a communication state, a driving mode, an output mode, and the like.

According to the present embodiment, the preset screen information can be provided using the pressure touch applied to the hour hand and the minute hand image, which represent the current time in the state where the function is not executed, or a specific function can be executed without going through a plurality of steps.

13 is a conceptual diagram for explaining a control method for performing different functions according to different touch methods.

The display unit 151 displays at least one icon 629 corresponding to a specific application. The controller 180 controls the display unit to execute the application and output an execution screen 629a when a general touch having a pressure value lower than a specific pressure is applied to the icon 629. [

Meanwhile, when the pressure touch having a specific pressure value is applied to the icon 629, the controller 180 activates the secret mode. In the secret mode, the display unit outputs a graphic image representing at least one function corresponding to the icon 629. [ In this case, execution of the application is limited.

According to the present embodiment, different functions can be executed when a general touch and a pressure touch are applied to one icon. The user can set the function of only the user to the specific icon.

14 is a conceptual diagram for explaining an embodiment in which the same function is controlled by different control methods based on different information. Here, the function may be executed using the time information output on the display unit 151. [

Referring to FIGS. 14A and 14B, the control unit 180 outputs a confirmation screen 635. However, the settlement screen 635 includes different amount information.

If the money amount information corresponds to a small amount based on a specific criterion, the control unit 180 executes the settlement function based on the general touch applied to the settlement screen 635. [ However, if the amount information corresponds to a large amount based on the specific criteria, the control unit 180 does not perform the settlement function even if the general touch is applied to the settlement screen 635. [

When the pressure touch is applied to the settlement screen 635, the controller 180 performs the settlement function. The display unit 151 may output an indicator 703 indicating the intensity of the pressure or the time when the pressure touch is applied when the pressure touch is applied. The control unit 180 completes the payment function when the pressure touch satisfies a predetermined criterion.

According to the present embodiment, when the information including the same function is different, the execution of the function can be controlled based on the touch input of another method. For example, if the information affects the profit or loss of the user by the information, it can be restricted to be executed only by the pressure touch.
