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 the 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.

Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen, It is an image that makes you feel the same as the space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means a parallax caused by the position of two eyes away from each other. When two eyes see two different images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt .

The stereoscopic display unit 152 may be applied to a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system). The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method.

Examples of the autostereoscopic method include a parallax barrier method, a lenticular method, an integral imaging method, and a switchable lens method. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image).

In addition, the 3D thumbnail image can generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and combine them to generate one 3D thumbnail image. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit receives a 3D image and extracts a left image and a right image from the 3D image, or receives a 2D image and converts it into a left image and a right image.

On the other hand, when a display unit 151 and a sensor (hereinafter, referred to as 'touch sensor') that detects a touch operation form a mutual layer structure (hereinafter referred to as a 'touch screen' It can also be used as an input device in addition to the 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 unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. 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.

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 may be provided as an example of the sensing unit 140. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. 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. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). 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 141 detects 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, 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.

In the case where the three-dimensional display unit 152 and the touch sensor have a mutual layer structure (hereinafter referred to as a 'three-dimensional touch screen') or a three-dimensional sensor that detects the touch operation and the stereoscopic display unit 152 are combined with each other The stereoscopic display unit 152 may also be used as a three-dimensional input device.

The sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144 as an example of the three-dimensional sensor.

The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) to which the touch is applied without mechanical contact using the force of the electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object 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 light change, thereby acquiring position information of the object to be sensed.

The audio output module 153 can 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 153 also outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 153 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 154 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 154 may output a signal for notifying the occurrence of an event by using 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 sound output module 153 so that the display unit 151 and the sound output module 153 may be classified as a part of the alarm unit 154 .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 155 may be vibration. The intensity and pattern of the vibration generated by the hit module 155 can be controlled by the user's selection or setting of the control unit. For example, the haptic module 155 may combine and output different vibrations or sequentially output the vibrations.

In addition to the vibration, the haptic module 155 may be configured to perform various functions such as a pin arrangement vertically moving with respect to the contact skin surface, a spraying force or a 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.

Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites 300 may optionally or additionally be responsible for satellite DMB transmission.

Of the typical operation of a wireless communication system, the BS 270 receives a reverse link signal from the mobile terminal 100. At this time, the mobile terminal 100 is connecting a call, transmitting or receiving a message, or performing another communication operation. Each of the reverse link signals received by the particular base station 270 is processed by the particular base station 270. The data resulting from the processing is transmitted to the connected BSC 275. The BSC 275 provides call resource allocation and mobility management functions, including the organization of soft handoffs between the base stations 270.

In FIG. 2B, the wireless APs connected to the mobile terminal 100 are illustrated as first, second, and third wireless APs 320 as an example. However, the number of wireless APs connected to the mobile terminal 100 can be variously changed according to the wireless communication environment in which the mobile terminal 100 is located. The WiFi location tracking system 300 is capable of tracking the location of the mobile terminal 100 when the mobile terminal 100 is connected to at least one wireless AP.

Next, the database 330 may store various information of arbitrary wireless APs located at different locations, as will be described in more detail with respect to a database 330 in which arbitrary wireless AP information is stored.

The information of any wireless APs stored in the database 300 includes at least one of MAC address, SSID, RSSI, channel information, privacy, network type, radar coordinate of the wireless AP, (Available in GPS coordinates), address of the AP owner, telephone number, and the like.

Since the database 330 stores any wireless AP information and location information corresponding to the wireless AP, the WiFi location server 310 can search the mobile terminal 100 in the database 330, The location information of the mobile terminal 100 can be extracted by searching for wireless AP information corresponding to the information of the wireless AP 320 connected to the wireless AP 320 and extracting location information matched with the retrieved wireless AP information.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location server 310 so that the mobile terminal 100 can acquire the location information.

Meanwhile, in the present invention, information processed in the mobile terminal 100 can be displayed using a flexible display. Hereinafter, the flexible display unit will be described in more detail with reference to the accompanying drawings.

3A and 3B are conceptual diagrams illustrating a flexible display unit 151 included in the mobile terminal 100 according to the present invention.

As shown in Figs. 3A and 3B, the flexible display portion 151 includes a flexible display that can be bent by a physical force externally applied. do. Here, the flexible display unit 151 may include both a general flexible display and an electronic paper.

Here, a typical flexible display refers to a durable display that is lightweight and does not break, made on a thin and flexible substrate that can be bent, bent, folded or rolled like paper while maintaining the display characteristics of conventional flat panel displays.

In addition, the electronic paper may be a display technology to which general ink characteristics are applied, and the point of using reflected light differs from a general flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

The sensing unit 140 may include a sensing unit 140 (see FIG. 1) on the flexible display unit 151, and the sensing unit 140 may sense flexing information of the flexible display unit 151. In this specification, the word 'warp' may include the meaning of 'warp', 'curl', 'folding', and 'bending'.

The sensing unit 140 may be disposed entirely on the flexible display unit 151 or may be partially disposed on the flexible display unit 151 and sense warping information of the flexible display unit 151. Here, the curvature information of the flexible display unit 151 may be the direction in which the flexible display unit 151 is bent, the degree of curvature, the position of curvature, the time of curvature, and the acceleration at which the curved flexible display unit returns to the original state. And may be various information that can be detected due to warping of the flexible display unit.

The control unit 180 may change the information displayed on the flexible display unit 151 or control the function of the mobile terminal 100 based on the warping information of the flexible display unit sensed by the sensing unit 140 Can be generated.

For example, as shown in FIGS. 3A and 3B, when the flexible display unit 151 is bent in response to an external physical force, the control unit 180 moves the flexible display unit 151 in a curved direction The screen image previously displayed on the flexible display unit 151 can be rearranged, separated, synthesized, or changed on the basis of the warped angles and the returning acceleration that returns to the original state.

3A and 3B, when the flexible display unit 151 is bent inward due to an external physical force, the controller 180 controls the flexible display unit 151, It is possible to display the screen images displayed on the display unit 151 so as to be close to each other. In another embodiment, when the flexible display unit 151 is bent outward by external physical force, the controller 180 may display the screen images displayed on the flexible display unit 151 to be spaced apart from each other.

In addition, the control unit 180 controls various methods of displaying information on the flexible display unit 151 so that the user can correctly recognize the information displayed on the flexible display unit 151 in response to the bending of the flexible display unit can do.

Meanwhile, as shown in FIG. 3B, the mobile terminal 100 may include a case surrounding the flexible display unit 151. FIG. In addition, the case may be formed so as to be bent together with the flexible display unit 151 by an external physical force in consideration of the characteristics of the flexible display unit 151.

Meanwhile, as described above, the control unit 180 may generate a control signal related to the function of the mobile terminal 100 according to the present invention, in response to the warping information of the flexible display unit 151.

As described above, the mobile terminal 100 has evolved into various types of designs, and accordingly, flexible displays are attracting attention because of their light and non-breaking characteristics. Flexible displays may be able to create new user interface areas that are limited or impossible to apply to existing glass substrate based displays. As the flexible display is attracting attention, there is a need for a user interface using the characteristics of the flexible display.

Hereinafter, the mobile terminal 100 capable of improving user's convenience in displaying screen information on the display unit 151 of the mobile terminal 100 that wraps the user's wrist, and a control method thereof .

FIG. 4 is a flowchart for explaining a method of displaying information in a watchdog mobile terminal according to the present invention. FIGS. 5A, 5B, 5C and 5D are conceptual diagrams for explaining a control method according to the flowchart shown in FIG. FIG. 6 is a conceptual diagram illustrating a method of allocating a control region in a mobile terminal according to the present invention.

FIG. 4 is a flowchart for explaining an embodiment of a mobile terminal 100 (see FIG. 1, or a watch mobile terminal) according to the present invention. The mobile terminal 100 includes a main body, a display unit 151 (see FIG. 1), a sensing unit 140 (see FIG. 1), and a control unit 180 (see FIG. 1). Here, the display unit 151 may be a flexible display unit or other display unit. Hereinafter, terms of a mobile terminal and a watch type mobile terminal can be used in combination, and even if a watch type mobile terminal is represented as a mobile terminal, it can be understood as a watch type mobile terminal.

Referring to FIG. 4, a step of sensing a position where the watch-shaped mobile terminal is worn on the wrist is detected (S410).

In the step of sensing the position where the mobile terminal is worn, various information related to the movement and position of the mobile terminal, such as the degree of tilting of the mobile terminal and the degree of movement, can be detected.

Here, the information related to the sensed wearing position of the mobile terminal may be the left or right wrist of the mobile terminal, the direction of the wrist worn by the mobile terminal, and the like.

The sensing unit 140 may include a sensor configured to measure at least one of a direction in which the mobile terminal is worn by the wrist, a position of the wrist, and a movement of the wrist in real time or at predetermined time intervals. Hereinafter, the information related to at least one of the direction of the wrist, the position of the wrist, and the movement of the wrist, sensed by the sensing unit 140, is referred to as "position information of the mobile terminal ". That is, the control performed by the control unit 180 of the mobile terminal based on the "position information of the mobile terminal" is based on at least one of the direction of the wrist worn by the mobile terminal, And the control unit 180 controls the mobile terminal.

Meanwhile, the sensing unit 140 may include an operation recognition sensor (not shown) as an embodiment for sensing the position information of the mobile terminal. The motion recognition sensor may include at least one of a terrestrial magnetism sensor, a gyro sensor, and an acceleration sensor.

A geomagnetic sensor is a sensor that detects the direction and magnitude of a geomagnetism and generates an electric signal using the detected direction and magnitude. The gyro sensor is a sensor that detects the rotational speed of the main body and generates an electric signal using the detected rotational speed. The acceleration sensor is a sensor that measures the direction of gravitational acceleration, detects an acceleration change in one direction, and generates an electric signal using the detected acceleration change.

Accordingly, the sensing unit 140 can detect whether or not the wrist is rotated. That is, the sensing unit 140 can detect the displacement of the wrist, that is, the rotation direction and the rotation angle, and generate an electric signal by using the rotation direction and the rotation angle. The sensing unit 140 can sense the direction of the main body that surrounds the wrist, that is, the position of the mobile terminal, by detecting the rotation direction and the rotation angle of the wrist.

 In another embodiment for obtaining the location information of the mobile terminal, the sensing unit 140 may include an eye search unit (not shown). The eye search unit can search the user's eyes using at least one of the camera sensor 121 (see FIG. 1) and the infrared sensor (not shown). A plurality of such camera sensors may be provided.

In particular, the infrared rays emitted from the infrared sensor may be reflected on the retina of the user's eye in a predetermined viewing range with respect to the display unit 151. [ The reflected infrared rays can be input to the eye search section. Thereafter, the eye search unit can search the user's field of vision using the input infrared ray or the user image obtained from the camera sensor 121. Accordingly, the sensing unit 140 can sense which part of the display unit 151 the user is looking at.

In another embodiment for obtaining the location information of the mobile terminal, the sensing unit 140 may include an illuminance sensor (not shown). The illuminance sensor can sense an external light and detect a part facing the ground and a part facing the ground of the display part 151. [

When the location information of the mobile terminal is obtained through the sensing unit 140, a step of allocating a specific area of the display unit 151 to the control area receiving the control command is performed (S420).

That is, the control unit 180 can determine the current state of the mobile terminal based on the user, based on the location information of the mobile terminal obtained through the sensing unit 140. Then, on the basis of the determination result, the area specification area optimized by the user to apply the control command can be assigned to the control area.

That is, the control unit 180 can select one of the display areas of the display unit 151 as a control area.

In operation S430, when the control region is allocated, the touch input of the user to the assigned control region is processed as a control command for controlling the operation of the mobile terminal (S430).

Here, the control region is a region for receiving from the user a control command for controlling the driving, operation, or currently output screen information of the mobile terminal. The control unit 180 controls the touch on the control region as a control command It can be recognized.

For example, at least one icon, a function icon, a function key, a visual key, and the like may be displayed in the control area, and the control unit 180 may perform a touch operation on at least one of the keys displayed in the control area If sensed, the touch performs a function or operation associated with the sensed key.

When the control area is allocated, the control unit 180 arranges control related information with priority on the assigned control area. The control unit 180, when the control area is insufficient, It is possible to display it off.

The control unit 180 may select an area to be allocated to the control area in consideration of the location information of the mobile terminal sensed through the sensing unit 140. In accordance with the location information of the mobile terminal, The position, size, and the like of the region to be changed can be changed.

In addition, when the location information of the mobile terminal is changed while the control area is allocated, the controller 180 can change the pre-allocated control area based on the changed location information of the mobile terminal. That is, in the mobile terminal according to the present invention, it is possible to allocate the control area so that the user can easily apply the control command to the watch-type mobile terminal in consideration of the relative position between the user and the mobile terminal.

5A, when the mobile terminal is worn on the left wrist of the user, it is relatively easy for the user to touch the display portion 151 with the right hand . That is, since it is easy for the user to touch the right side region with respect to the longitudinal direction A of the mobile terminal, the control unit 180, as shown in FIG. 5A, The right area 510 can be allocated as a control area on the basis of the longitudinal direction A of the mobile terminal.

When the upper end of the mobile terminal is allocated as the control area, the user's finger may cover the display part 151 for touching the control area, Can be preferentially allocated to the control area. In addition to this, the user may be easier to touch the lower end of the display unit 151, which is relatively close to the user's torso or finger, so that the lower end of the display unit 151 is preferentially assigned to the control area . Therefore, as shown in (b) of FIG. 5, in the mobile terminal according to the present invention, the right lower end region of the mobile terminal can be allocated to the control region 510. [

Meanwhile, the information displayed in the control area may vary according to the function currently being performed in the mobile terminal, the operation state of the mobile terminal, the user's request, and is not limited to a specific example.

It will be obvious to those skilled in the art that the control area 510 is not allocated to the control area 510, and therefore the control command is not received in the area other than the control area 510. [

In this manner, the control unit 180 can allocate a control region, which is relatively easy for the user to access, according to the position where the mobile terminal is worn, using the detection result detected by the sensing unit 140. [ The control unit 180 controls the position of the control area in the first state in which the mobile terminal is worn on the left wrist of the user, And the control area may be allocated to the other side of the display unit 151 in a second state where the mobile terminal is worn on the right wrist of the user.

In this case, the control area is located at the right lower end of the display unit 151 with respect to the imaginary center axis (the longitudinal direction A) of the mobile terminal body in the first state, and in the second state, And may be located at the lower left side of the display unit 151 with respect to the central axis of the display unit 151. [

Also, the control unit 180 may output the function icon to the allocated control area only when it is necessary to output the function icon for receiving the control command related to the operation of the mobile terminal. That is, in the control area, information related to control of the mobile terminal may be displayed as needed.

On the other hand, the specific area in a state in which the function icon is not output in the assigned control area may have the same attributes as the other areas. That is, if a web page is displayed in another area, the web page displayed in the other area and the subsequent information may be displayed in the assigned control area. When the function icon is to be output in the control area, the control unit 180 may overlap the information output to the display unit 151 and output the function icon.

If a predetermined type of touch is applied to the allocated control area in a state where no function icon is displayed in the allocated control area, the controller 180 controls the current operation of the mobile terminal And at least one of the basic operation function icons of the mobile terminal. That is, when a predetermined touch input (for example, a long touch input, a double touch input, or the like) is applied to the assigned control region or its periphery, the control unit 180 outputs the function keys to the assigned control region .

5B, the control unit 180 controls the display area based on the position information of the mobile terminal to display the control area having the predetermined size Can be assigned. For example, as shown in FIG. 5B, when the mobile terminal body is formed in a circular shape, the control unit 180 can assign a region corresponding to a predetermined angle among the circular bodies to the control region, and further, Of the regions corresponding to the angles, a specific portion (e.g., the circumferential portion 520 of the mobile terminal) can be assigned to the control region.

5C, the control unit 180 may assign such a specific portion 530 to the control region and receive a touch on the assigned control region as a control command.

Meanwhile, in the mobile terminal according to the present invention, clock information may be displayed on the display unit 151 basically. That is, in the present invention, clock information can always be displayed to the user by utilizing the characteristics of the watch-type mobile terminal. Whether or not the clock information is continuously displayed can be determined based on the user's selection. That is, when the display unit 151 is turned on and the screen corresponding to the specific application or the screen information based on the user's request is not displayed on the display unit 151, May be displayed. The clock information may be displayed on the display unit 151 such that the screen information corresponding to a specific application or the screen information based on the user's request is displayed on the display unit 151 and overlapped with the information .

6, when the mobile terminal is worn on the user's right wrist, the controller 180 controls the left lower end of the control region 610 with respect to the longitudinal direction A, . ≪ / RTI >

In addition, when the position information of the mobile terminal is changed due to the movement of the user's wrist or the direction of the user's gaze, the controller 180 may change the position of the allocated gain region based on the changed location information of the mobile terminal have.

For example, when the wrist at the position shown in (a) of Fig. 6 is inclined further downward, the control region is formed at the center of the reference axis corresponding to the longitudinal direction A, as shown in Fig. 6 (b) , It can be assigned to a lower area than the control area shown in Fig. 6 (a).

On the other hand, the control unit 180 may determine whether to reallocate the control area according to the degree of movement of the wrist or the direction of the user's gaze. That is, the control unit sets one of the regions, at least partially different from the pre-allocated control region, to be the control region so that the position of the phase control region is changed only when the detected wrist movement or the change range of the visual- Can be reassigned.

As described above, in the mobile terminal and its control method according to the present invention, a display area for enhancing the convenience of the user is allocated as a control area, so that a user can more easily apply a control command to the mobile terminal have.

Hereinafter, a method for displaying control-related information in an allocated control area will be described in detail with reference to the accompanying drawings. 7A, 7B, 8A, 8B, 9A, and 9B are conceptual diagrams illustrating a method of displaying a control region in a mobile terminal according to the present invention.

In the following description, it is assumed that the watch-type mobile terminal is worn on the user's right wrist. As shown in FIG. 7A, when an event is generated in the mobile terminal, the control information related to the generated event is controlled These control information can be preferentially displayed in the control area in conjunction with the occurrence of the event.

Here, an event may include something occurring in an application installed in the mobile terminal. For example, when information is received from an external server or an external terminal in connection with a specific application, an event is expressed as " . In addition, an event may be generated in the application itself installed in the mobile terminal. For example, in the alarm function application, the alarm time is reached and the alarm information is output.

Referring to FIG. 7A, when a message is received from an external server or an external terminal in a mobile terminal in which a message function application is installed as shown in FIG. 7A, the control area 710 stores a received message And at least one function key for processing an operation related to the operation. On the other hand, the size of the control area 710 can be varied corresponding to the number of function keys to be displayed.

7B, when a predetermined touch (for example, a long touch) is applied to the display unit 151, the control unit 180 controls the control unit 720 to move the control unit 720, In order to inform the information of the application currently running on the mobile terminal, an icon of the running applications may be output. The control unit 180 controls the display unit 151 to display the currently used application in the mobile terminal with respect to the assigned control area 720 when a touch of a predetermined type (for example, a long touch) The icon of the recently used application may be output in order to inform the user of the information.

In this way, various control information can be output to the control area according to the current state of the mobile terminal.

Meanwhile, in the mobile terminal according to the present invention, the size of the control area may be variable according to the amount of information to be displayed in the control area. The control part 180 may preferentially allocate the peripheral area of the mobile terminal as the control area have. 8A, when there is a request to display control information related to the operation of the mobile terminal, for example, when any information is displayed, the control unit 180 transmits the control information to the control area Can be displayed. When the amount of control information to be displayed is large, the control unit 180 can display such control information on the peripheral region 810 of the mobile terminal body, as shown in Fig. 8B.

If any of the information displayed in the peripheral region 810 is selected and there is additional control information to be displayed in association with the selected information, the control unit 180 controls the peripheral region 810 , It is possible to allocate an area which is easy for the user to take a touch in consideration of the position of the mobile terminal to the control area and to display the additional control information on the additional control area 820 as described above.

On the other hand, when any one of the information displayed in the perimeter area 810 is selected, the controller 180 gives the visual effect to the selected item 811 to inform the user that the item 811 has been selected can do. For example, as shown, the control unit 180 may notify the user that the item 811 is selected by displaying a graphic object on one edge of the selected item 811. [

Further, the control unit 180 can give information about whether or not the function corresponding to the item is turned on or off, through the graphic object, around the item corresponding to the function to be turned on or off. For example, when the GPS and WiFi functions are on (or in the activated state), the controller 180 displays graphical objects 812a and 813a around the items 812 and 813, 812, and 813 are in an on state.

On the other hand, when the control unit 180 displays the control information, the control unit 180 sequentially displays the control information in the areas based on the predetermined priority without considering the location information of the mobile terminal, Lt; RTI ID = 0.0 > areas. ≪ / RTI >

For example, when the control unit 180 receives a control command along the peripheral region of the mobile terminal or is set to display the control information, the control unit 180 displays information around the peripheral region, Accordingly, the mobile terminal can be driven. For example, as shown in (a) of FIG. 9A, in a state where information is displayed on the display unit 151, the control unit 180 controls the peripheral area of the mobile terminal The user can perform a function associated with the touch of the preset method, as shown in FIG. 9B.

Here, the function associated with the predetermined type of touch may be, for example, a scrolling function. These functions include an operation currently performed in the mobile terminal, a driving state, a kind of information output, Type, and so on.

As described above, using the peripheral region of the mobile terminal to display the control information or receive the control command also does not impair the information displayed on the display unit 151 as much as possible, In a restrictive watch type mobile terminal, user convenience can be enhanced.

Hereinafter, a method for displaying information on a watch-type mobile terminal in consideration of a relative position of a user and a watch-type mobile terminal will be described in detail with reference to the accompanying drawings in order to enhance user's convenience. FIGS. 10A, 10B, 11A, 11B, 11C, and 11D are conceptual diagrams for explaining a method for changing the display state of screen information according to the position of the mobile terminal in the mobile terminal according to the present invention.

In the mobile terminal according to the present invention, the display direction of the information can be determined in consideration of the relative position of the mobile terminal and the user. That is, the controller 180 can determine the display direction of the screen information displayed on the mobile terminal based on the location information of the mobile terminal sensed through the sensing unit 140. [

For example, as shown in FIG. 10A, when the viewing direction of the user and the wearing position of the mobile terminal correspond to the imaginary first reference axis A, the controller 180 controls the virtual reference axis It is possible to display the screen information in a direction perpendicular to the screen A. When the user's sight line direction corresponds to the imaginary second reference axis B as shown in FIG. 10A, the controller 180 controls the direction perpendicular to the imaginary second reference axis B The screen information can be displayed. That is, the controller 180 can determine the direction of the information displayed on the display unit 151 so that the information displayed on the display unit 151 coincides with the direction of the user's gaze.

The control unit 180 may control the display unit 151 to change the display direction of the screen information displayed on the display unit 151 in accordance with the change of the location information of the mobile terminal. For example, the controller 180 may display the screen information in a portrait format or a landscape format according to the direction of the wrist or the direction of the user's gaze.

In addition, the mobile terminal 100 according to another embodiment of the present invention may be configured to display the display information on the display unit 151 in consideration of the position information of the mobile terminal, for example, The area can be determined. Accordingly, the mobile terminal 100 can display the screen information on the portion of the display unit 151 facing the user's gaze, in consideration of the user's gaze. As a result, the convenience of the user can be improved.

For example, when there is event information, notification information, or the like, the control unit 180 can display such information in preference to a relatively easy-to-recognize area. For example, the information display area 1010, which is relatively easy for the user to recognize, may be the upper part based on the direction of the user's gaze, as shown in Fig. 10 (a).

Furthermore, the control unit 180 can select a display area on which information is to be displayed on the display unit 151. [ Specifically, the control unit 180 can select the position, size, and shape of the information display area. Accordingly, a portion of the display portion 151 that is visually recognizable to the user out of the range of the user's gaze can be designated as the information display region 1010.

On the other hand, when the wrist movement is detected or the user's viewing direction is changed as shown in FIG. 10B, the controller 180 controls the display unit 151 to display the information on the screen, (1020).

For example, as shown in the figure, when the wrist is bent by about 15 degrees according to the movement of the wrist, the control unit rotates the wrist by 15 degrees in a direction opposite to the direction in which the wrist is bent, corresponding to the movement of the wrist, can do. Meanwhile, as shown in the figure, the controller 180 can apply the above-described examples in the same way as long as information is displayed on the display unit 151 as well as the state in which the event information is output.

When the direction of the wrist is changed and the direction of the wrist is changed, the controller 180 controls the display unit 151 based on the direction of the newly sensed wrist through the sensing unit 140 Can change the display direction of the screen information displayed on the screen.

In this way, the sensing unit 140 senses that the mobile terminal body rotates about a virtual plane parallel to the display unit 151, and the controller 180 controls the display unit 151 ) Controls the display unit so that the screen information displayed on the display unit maintains the output form in the direction of the user's eyes. Here, the screen information displayed on the display unit 151 may be moved in a direction opposite to the rotation direction of the main body.

If the amount of information to be displayed on the information display area 1020 can not be displayed at one time in the information display area 1020, the controller 180 may display the information display area 1020, The display unit 151 can be controlled so that the information displayed on the display unit 151 is sequentially changed. In this case, when the user views the information display area 1020, the user can feel the information displayed on the information display area 1020 as flowing. If the amount of information to be displayed on the information display area 1020 can not be displayed all at once in the information display area 1020, Information displayed in the information display area 1020 can be changed corresponding to the touch. That is, here, the touch of the preset method may be a drag, a slide touch, or the like. In this manner, when the predetermined type of touch is applied, the control unit 180 can output information that is not displayed on the display unit 151 among the information to be displayed on the display unit 151.

On the other hand, when the information display area to display the screen information is determined on the display unit 151 in consideration of the direction of the user's wrist or the user's gaze, the method of displaying information in the information display area is more specific . For example, as shown in FIG. 11A, when the information display area is a region having a predetermined size from the virtual start point A, the control unit 180 displays event information, etc. on the basis of the virtual start point A Can be displayed. This information can be displayed on the basis of the perimeter area of the display unit 151. In this case, the display unit 151 can display the event information .

On the other hand, the kinds of information displayed in the perimeter area may vary, and as shown in the figure, when an event is generated, the event information may be temporarily displayed and then disappear. In addition, even if no event has occurred, information related to the widget can be displayed in the perimeter area. For example, the controller 180 may place the widget in the perimeter area. Thus, the user can utilize the widget through this perimeter area. The perimeter area is divided into a plurality of areas, and a plurality of widgets may be displayed, or only one widget may be displayed in one perimeter area. How the widget is placed on the perimeter area may be based on the user's selection. In addition, the type of the widget displayed in the perimeter area may vary depending on the preference of the user.

11B and 11B, when there is event information, notification information, and the like on the preset specific area 1110, the controller 180 gives priority to such information Can be displayed. The specific area 1110 may be a relatively easy area for the user to recognize the information displayed on the display unit, which is determined based on the location information of the mobile terminal. Further, the position of this area can be changed in conjunction with the change of the position of the mobile terminal.

In the case where there are a plurality of events or notification information, as shown in (a), (b) and (c) of FIG. 11C, based on the order in which the events are generated, Or may be sequentially displayed in the information display area 1120 based on the user's selection.

On the other hand, when an event is generated, the controller 180 may display the count information in one area of the display unit 151 so that the number of generated events can be known. For example, as shown in (a) of FIG. 11D, the control unit 180 can display the number of events that occurred in a specific application in one area 1130. In the message function application, when two message reception events occur, a number '2' may be displayed in one area 1130.

As another example, the control unit 180 can display the number of applications in which an event has occurred in one area 1130, as shown in (b) of FIG. 11. That is, when an event occurs in the message function application and the SNS function application, the control unit 180 may display a number '2' in one area 1130 to notify that an event has occurred in the two applications. That is, in this case, the number of applications in which an event has occurred can be displayed in the one area 1130, not the number of events generated in the corresponding application.

As another example, the control unit 180 may display the total number of generated events in one area 1130 of the display unit 151, regardless of the end of the application, as shown in (c) of FIG. 11 . That is, when one, two, and three events are generated in three different applications, the controller 180 displays numerical information corresponding to six events, which is the total number of generated events, Can be displayed in one area (1130) of the display section (151). Here, the position of one area is irrelevant to any area existing on the display unit 151. [

As described above, in the watch-type mobile terminal and its control method according to the present invention, by displaying the event information in a relatively easy area where the user can recognize the information displayed on the display unit 151, have.

Also, in the watch-type mobile terminal according to the present invention, the position where the mobile terminal is worn can be sensed and the display position of the information displayed on the display unit can be determined according to the sensed position. That is, in the watch-type mobile terminal according to the present invention, it is possible to control the screen information so that the user can more conveniently use the information displayed on the display unit, considering the position where the mobile terminal is worn.
