Referring to FIG. 1, an A / V (Audio / Video) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes image frames such as still images or moving images obtained by the image sensor in the video communication mode or the photographing mode. The processed image frame can be displayed on the display unit 151. [

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ Two or more cameras 121 may be provided depending on the use environment.

The microphone 122 receives an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes the voice data as electricity.

The wear detection sensor 143 may include a temperature sensor, a bowing sensor, a color sensor, and a photoplethysmograph (PPG) sensor. The PPG sensor estimates the heart rate activity by measuring the blood flow through the blood vessel using the optical characteristics of the living tissue. The pulse wave is a pulsating waveform that appears when the blood is discharged from the heart. It can be measured through the change of the blood flow due to the relaxation and contraction of the heart and the resulting change in the volume of the blood vessel. The optic pulse wave observes the characteristics such as reflectance, absorptivity, and transmittance of the light of the living tissue when the volume of the blood vessel changes by using the light, and measures the pulse through the change. The PPG sensor includes a light emitting portion and a light receiving portion. The light emitting portion irradiates light. The light receiving unit receives the reflected light reflected by the volume change of the blood vessel according to the change of the blood flow.

The output unit 150 is for generating output related to the visual, auditory or tactile sense and includes a display unit 151, an audio output module 152, an alarm unit 153, and a haptic module 154 .

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the photographed and / or received video or UI and GUI are displayed.

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED) 3D display).

Some of these displays may be transparent or light transmissive so that they can be seen through. This can be referred to as a transparent display, and a typical example of the transparent display is TOLED (Transparent OLED) and the like. The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see an object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another or may be disposed integrally with each other, or may be disposed on different surfaces.

(Hereinafter, referred to as a 'touch screen') in which a display unit 151 and a sensor for sensing a touch operation (hereinafter, referred to as 'touch sensor') form a mutual layer structure, It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display portion 151 or a capacitance generated in a specific portion of the display portion 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If 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.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 is a sensor that detects the presence or absence of an object approaching a predetermined detection surface or in the vicinity thereof without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

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. And to detect the proximity of the pointer by the change of the electric field along the proximity of the pointer when the touch screen is electrostatic. In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch" The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor detects 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, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 152 also outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration. The intensity and pattern of the vibration generated by the hit module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

In addition to the vibration, the haptic module 154 may include a pin arrangement vertically moving with respect to the contact skin surface, a spraying force or suction force of the air through the injection port or the suction port, a touch on the skin surface, contact with an electrode, And various tactile effects such as an effect of reproducing a cold sensation using an endothermic or exothermic element can be generated.

The haptic module 154 can be implemented not only to transmit the tactile effect through the direct contact but also to allow the user to feel the tactile effect through the muscular sensation of the finger or arm. The haptic module 154 may include two or more haptic modules 154 according to the configuration of the portable terminal 100.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM A disk, and / or an optical disk. The mobile terminal 100 may operate in association with a web storage that performs a storage function of the memory 160 on the Internet.

The interface unit 170 serves as a path for communication with all external devices connected to the mobile terminal 100. The interface unit 170 receives data from an external device or supplies power to each component in the mobile terminal 100 or transmits data to the external device. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, A video input / output (I / O) port, an earphone port, and the like may be included in the interface unit 170.

The identification module is a chip for storing various information for authenticating the use right of the mobile terminal 100 and includes a user identification module (UIM), a subscriber identity module (SIM), a general user authentication module A Universal Subscriber Identity Module (USIM), and the like. Devices with identification modules (hereinafter referred to as "identification devices") can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port.

When the mobile terminal 100 is connected to an external cradle, the interface unit may be a path through which power from the cradle is supplied to the mobile terminal 100, or various command signals input by the user to the cradle may be transmitted It can be a passage to be transmitted to the terminal. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

The controller 180 typically controls the overall operation of the mobile terminal. For example, voice communication, data communication, video communication, and the like. The control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [

The controller 180 may perform a pattern recognition process for recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

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.

[

2 is an exemplary view of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 2, the case of the portable terminal 100 to which the embodiment of the present invention is applied includes a front case 193 and a rear case 195. The front case 193 and the rear case 195 may be made of a soft material that is folded or bent depending on the size and condition of the display unit 151, or may be configured with a minimized size. Specifically, the display unit 151 and the camera unit 121 can be disposed in the front case 193. [

The display unit 151 may be configured to be able to input information by a user's touch by operating as a touch screen by overlapping the touch pad with a layer structure. In addition, the camera unit 121 may be adapted to photograph an image or a moving image of a user or the like.

On the side of the rear case 195, the user input unit 130 may be disposed. The user input unit 130 disposed on the side of the rear case 195 may include at least one key for obtaining a user input including a communication key, a menu key, and the like.

The sensing unit 140 may be disposed on the rear case 195. The sensing unit 140 may include a wear detection sensor 143 for detecting whether the user wears the mobile terminal 100. The wear detection sensor 143 may include a color sensor, a PPG sensor, a temperature sensor, a proximity sensor, an electric signal sensor, and the like. A method of detecting whether or not the user wears will be described in detail with reference to FIG. 3 through FIG.

The front case 193 or the rear case 195 may be provided with various interface units and user input units in addition to the user input unit 130, the display unit 151 and the camera unit 121 described above.

The mobile terminal 100 stores personal information of a user. In addition, the user can pay for the goods and services using the mobile terminal 100. Accordingly, the mobile terminal 100 provides a locking function to prevent the unauthorized access of the user. The unlocking user interface of the general mobile terminal 100 provides drawing pattern recognition and degree of password input.

In the case of the drawing pattern recognition currently provided, the terminal displays nine points of 3 * 3, recognizes the drawing pattern connecting the nine points, that is, consecutive touch inputs connecting the nine points, do. However, in order for the user to input such a drawing pattern without inconvenience, a display unit 151 having a predetermined size or more is required. Thus, the wearable mobile terminal 100, which uses a relatively small size display as in the present invention, requires a new unlocking interface.

Drawing pattern recognition can also be easily dealt with when watching from the side. In the case of the password input interface, the password can also be easily exposed. Therefore, a lock pattern other than the user of the mobile terminal 100 can not be easily grasped.

3 to 9, an unlocking user interface of the mobile terminal 100 according to an embodiment of the present invention will be described.

FIG. 3 shows a flowchart of an unlocking operation of a mobile terminal according to an embodiment of the present invention.

The control unit 180 determines whether the user uses the mobile terminal 100 using the sensing unit 140 (S101). In a specific embodiment, the sensing unit 140 may include a temperature sensor. The temperature sensor can sense whether a temperature above the reference temperature is detected. At this time, when the temperature sensor senses a temperature equal to or higher than the reference temperature, the controller 180 may determine that the user wears the mobile terminal 100.

In another specific embodiment, the sensing unit 140 may include a PPG sensor. The PPG sensor can detect the movement of the user's blood flow. When the PPG sensor senses the movement of the blood flow, the controller 180 may determine that the user wears the mobile terminal 100.

In yet another specific embodiment, the sensing unit 140 may include a proximity sensor. The proximity sensor can detect the approach of the object. When the proximity sensor detects the approach of the object, the controller 180 may determine that the user wears the mobile terminal 100. [

In yet another specific embodiment, the sensing unit 140 may include a temperature sensor. The temperature sensor may sense the temperature of the object or the ambient contact with the mobile terminal 100. When the user wears the mobile terminal 100, the temperature sensor may detect a temperature higher than a predetermined reference temperature due to the body temperature of the user. Accordingly, when the temperature sensor senses a temperature equal to or higher than a predetermined reference temperature, the controller 180 can determine that the user wears the mobile terminal 100.

In another specific embodiment, the sensing unit 140 may include an electrical signal sensor and a color sensor. A method of determining whether or not the user wears the mobile terminal 100 using the electric signal sensor and the color sensor will be described with reference to FIGS.

FIG. 4 shows that a mobile terminal according to an embodiment of the present invention determines whether it is worn using a buckle.

The front case 193 of the mobile terminal 100 according to the embodiment of the present invention includes a buckle for wearing the mobile terminal 100 of the user. At this time, the buckle is a conductor capable of transmitting electrical signals. The mobile terminal 100 also includes an electric signal generator (not shown) for generating an electric signal and transmitting the electric signal to either the upper connection part 201 or the lower connection part 203 of the buckle. At this time, an electric signal sensor is connected to a connection portion where the electric signal generated by the electric signal generating portion is not transmitted. Accordingly, when the upper connecting part 201 and the lower connecting part 203 of the buckle are connected, the electric signal sensor can sense the electric signal generated by the electric signal generating part. When the electric signal sensor senses the electric signal, the control unit 180 may determine that the user wears the mobile terminal 100. [

In this case, the electrical signal generator may be a piezoelectric element. In particular, the piezoelectric element can be a film type that can be easily bent. When pressure is applied to the piezoelectric element in a certain direction, electricity is generated on both sides of the plate by positive and negative charges proportional to the external force. If the piezoelectric element is attached to the front case 193 or the rear case 195 and the front case 193 or the rear case 195 is bent so that the user wears the mobile terminal 100, . However, if the user wears the mobile terminal 100 in this way, the controller 180 may erroneously determine that the user wears the mobile terminal 100 even if the user simply buckles the mobile terminal 100 can do.

In another embodiment, the electric signal generating part is a piezoelectric element, and the electric signal sensor can receive an electric signal without using a buckle. Specifically, the electrical signal generating unit including the piezoelectric element can be directly connected to the electrical signal sensor. The electric signal generating unit generates an electric signal according to whether the front case 193 or the rear case 195 is warped. At this time, the electric signal sensor senses the electric signal whether or not the buckle is connected. The control unit 180 may determine whether the user wears the mobile terminal 100 because the electric signal sensor detects the electric signal. However, if the front case 193 or the rear case 195 is bent without the user wearing the mobile terminal 100, the control unit 180 determines that the user wears the mobile terminal 100. In this case, It can be erroneously judged that the wearer 100 is worn.

FIG. 5 shows that a mobile terminal according to another embodiment of the present invention determines whether it is worn using a color sensor.

The mobile terminal 100 according to another embodiment of the present invention includes a colun sensor. At this time, the color sensor is disposed in the rear case 195. The color sensor includes a light emitting portion 211 and a light receiving portion 213. The light emitting portion 211 irradiates light to the object. The light receiving unit 213 receives reflected light that reflects the light irradiated by the object. The light receiving unit 213 analyzes the red, green, and blue components of the reflected light to detect the color of the object.

The light emitting portion 211 can emit light of a specific color. When the user wears the mobile terminal 100, the light irradiated by the light emitting unit 211 is reflected by the user's skin or clothes. At this time, the light receiving unit 213 senses the color of the reflected light. The control unit 180 can determine whether the user wears the mobile terminal 100 whether or not the light receiving unit 213 senses a specific color such as the color of light irradiated by the light emitting unit 211. [ The light of a specific color may be green and blue having a wavelength of about 400 nm to 600 nm. If the length of the wavelength is relatively small, the transmittance is low and is well reflected. Accordingly, the green or blue light can be reflected more accurately than other colors when the user wears the mobile terminal 100. [ Therefore, using the light of green or blue can increase the reliability of judgment of wearing. However, when the user determines whether the mobile terminal 100 is worn by such a method, the light emitting unit 211 must continue to irradiate light, which may waste power of the mobile terminal 100. [ In addition, when the mobile terminal 100 is not worn, the light continuously irradiated may cause inconvenience to the user.

To solve this problem, the light emitting portion 211 can irradiate light only when the front case 191 or the rear case 193 is bent. To this end, the mobile terminal 100 may include a bowing sensor. The deflection sensor can use a piezoelectric element as in the embodiment of Fig. Specifically, when the mobile terminal 100 is bent, the piezoelectric element receives a constant pressure to generate an electric signal, and an electric signal sensor included in the bending sensor can sense the electric signal. When the warp sensor detects warp, the light emitting unit 211 can emit light.

If the user wears the mobile terminal 100, the control unit 180 turns on the display unit 151 (S103). When the display unit 151 is turned on, the controller 180 can receive the touch input to the display unit 151 and display the user interface on the display unit 151. [

The control unit 180 displays the time on the display unit 151 (S105). At this time, the controller 180 may display the time using a plurality of graphical user interface (GUI) elements. The plurality of time display GUI elements may include at least one of a plurality of time reference indications and clock hands. The time reference display may include a number, a figure, a point, etc. as a reference of the position of the hour hand as a reference for displaying the time. Or the time reference indicator may be a number indicating the time without a clock needle. That is, in the specific embodiment, the control unit 180 can display the time using a plurality of numbers and a clock hands. At this time, the hands of the watch include the hour hand and the minute hand. The clock hands may also include a second hand.

The control unit 180 determines whether an input for starting the lock pattern input mode is received (S107). The lock pattern input mode is an operation state of the mobile terminal 100 for inputting a lock pattern. In a specific embodiment, the input that initiates the lock pattern input mode may be a long touch input for a particular location. Accordingly, the controller 180 can determine whether a long touch input for a specific position is received. In another specific embodiment, the input to initiate the lock pattern input mode may be a multi-touch input that touches a certain number of points or more.

When the input for starting the lock pattern input mode is received, the controller 180 starts the lock pattern input mode and receives the user input for the lock pattern using the current time display (S109). In a specific embodiment, the control unit 180 may receive user input for a lock pattern based on at least one of a plurality of visual display GUI elements. Specifically, the control unit 180 may receive a user input for a lock pattern based on at least one of a plurality of time reference indications and a clock hands.

The locking pattern of the mobile terminal 100 may be to move the hands of the clock to a predetermined position. At this time, the controller 180 may stop the movement of the clock hands when the lock pattern input start command is received to input the lock pattern of the user. The controller 180 then receives a user input for the hand. The control unit 180 can receive user input for the hour hand, the minute hand, and the second hand, respectively. The control unit 180 can receive the touch input for a specific position and move the position of the hand. Specifically, the controller 180 may receive the touch input of the user's clock hands and move the position of the clock hands. Also, the control unit 180 may be a touch input for a virtual figure surrounding the numbers for displaying the time. At this time, the virtual figure may be either a circle or a rectangle. At this time, when there is a multi-touch input for touching more than two points, the controller 180 can move the hands faster than the moving speed of a general clock needle. In addition, the controller 180 may receive the user input through the user input unit 130 and move the position of the hands. 6 (a) shows a current time display screen of the mobile terminal 100. As shown in FIG. 6 (b) shows that the control unit 180 moves the hour hand in accordance with the touch input of the user with respect to the hour hand. 6C shows that the control unit 180 moves the minute hand according to the touch input of the user with respect to the minute hand. 6D shows that the controller 180 moves the second hand according to the touch input of the user with respect to the second hand.

The position at which the clock hands are moved may be a point indicating a preset time. For example, the lock pattern may be to move the hands of the clock to 6:30. In another specific embodiment, the position for moving the hour hand may be a predetermined time or a predetermined time after the position of the hour hand at the start of the lock pattern input mode. At this time, the controller 180 can display the time when the clock hands moved from the current time using numbers, +, and - symbols. For example, the lock pattern may be to move the hands of the clock 3 hours and 30 minutes later than the position of the hands at the start of the lock pattern input mode. 7 (a) shows the current time display screen of the mobile terminal 100. 7 (b) shows that the controller 180 receives the multi-touch input of the user and starts the locked pattern input mode. 7C shows that the controller 180 moves the hands of the clock according to the multi-touch input of the user after 3 hours and 30 minutes. At this time, the control unit 180 displays the shifted time of 3:30 from the position of the hand of the clock at the beginning of the lock pattern input mode as +3: 30.

Such a lock pattern has a number of various cases. Therefore, it is more secure than existing lock patterns. In addition, the lock pattern can be used in a small touch area by using a clock hand.

The locking pattern of the mobile terminal 100 according to another embodiment may be a drawing pattern that moves a plurality of graphics having different shapes displayed on the time display screen and then connects the plurality of graphics in a predetermined order. In this case, the movement of the plurality of graphic objects may be to move clockwise or counterclockwise around the fixed point of the hands. This will be described in detail with reference to FIG.

FIG. 8 illustrates an unlocking user interface using a plurality of graphic objects displayed on a time display screen of a mobile terminal according to another embodiment of the present invention. 8 (a) shows the start of the lock pattern input mode. 8B shows that the position of a plurality of graphic objects is rotated clockwise around the fixed point of the hands of the user according to the user's touch input. 8C shows that the control unit 180 displays a drawing pattern connecting a plurality of graphic objects according to a touch input of a user. This locking pattern can produce a number of different cases with fewer points than the existing drawing pattern. Therefore, such a locking pattern is suitable for use in the display unit 151 which is excellent in security but is relatively small in size.

The locking pattern of the mobile terminal 100 according to another embodiment may be a drawing pattern connecting a plurality of numbers for time display. Specifically, it may be a touch input pattern that connects a plurality of preset numbers in a predetermined order. This will be described in detail with reference to FIG. FIG. 9 illustrates an unlocking user interface using numbers as time reference marks in a time display screen of a mobile terminal according to another embodiment of the present invention. 9 (a) shows the current time display screen. 9 (b) shows the start of the lock pattern input mode. At this time, the controller 180 may display a plurality of numbers that are time reference marks. In the embodiment of FIG. 9, twelve numbers are displayed. 9C shows that the controller 180 displays a drawing pattern connecting a plurality of numbers according to a touch input of the user.

The control unit 180 displays the lock pattern based on the user input (S111). Specifically, the control unit 180 can display the lock pattern input by the user.

The control unit 180 determines whether the user input for the preset lock pattern and the lock pattern coincide (S113). And the lock pattern of the mobile terminal 100 moves the clock hands to a predetermined position. In a specific embodiment, the controller 180 may determine whether the position of the pre-set hands is coincident with the position of the hands of the hands. Specifically, the control unit 180 can determine whether the position of the hands is a position corresponding to a preset time. In another specific embodiment, the controller 180 may determine whether the position of the hour hand is a position corresponding to a time shifted by a predetermined time from the start of the lock pattern input mode. In another specific embodiment, when the locking pattern of the mobile terminal 100 is a drawing pattern that moves a plurality of graphics having different shapes displayed on the time display screen and then connects the plurality of graphics in a predetermined order, Can determine whether or not the positions of a plurality of graphic shapes previously set and the positions of a plurality of graphic objects input by the user are coincident with each other and determine whether a drawing pattern that connects a predetermined drawing pattern and a plurality of graphic objects coincide with each other. In another specific embodiment, when the locking pattern of the mobile terminal 100 is a drawing pattern connecting numbers that are time reference marks, the control unit 180 may determine whether the preset drawing pattern and the user- have.

If the user input for the preset lock pattern matches the lock pattern, the controller 180 cancels the lock (S115). If the user input for the preset lock pattern and the lock pattern do not match, the control unit 180 may indicate that the user input for the preset lock pattern and the lock pattern do not match. If the user input to the lock pattern does not coincide more than a predetermined number of times, the control unit 180 may not receive the input of the lock pattern for a predetermined time. At this time, the controller 180 may indicate that the input of the lock pattern is limited for a predetermined time.
