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 watch-type mobile terminal or the proximity sensor 141 near 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. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Further, the control unit 180 controls the watch-type mobile terminal 100 so that different operations or data (or information) are processed depending on whether the touch on the same point on the touch screen is a proximity touch or a contact touch can do.
The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

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 mobile terminal 100 of the current watch type or the running application program.
On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. 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 photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected 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.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 100. The satellite aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. 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 may optionally or additionally be responsible for satellite DMB transmissions.
The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.
The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.
The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.
The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.
The mobile terminal 100 connected to the wireless AP can transmit the location information request message to the Wi-Fi location server.
The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi position location server through the mobile terminal 100, or may be transmitted from the wireless AP to the Wi-Fi location server.
The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.
As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.
Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.
As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.
The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.
The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information.

Specifically, the upper piezoelectric element group 450 and the lower piezoelectric element group 470 are deformed in length according to the applied current, so that the screen curvature of the flexible display 251 can be adjusted. The upper piezoelectric element group 450 may be named as the first shape deforming portion, and the lower piezoelectric element group 470 may be named as the second shape deforming portion, respectively.

The control unit 180 of the flexible watch type mobile terminal 200 can control the printed circuit board 420 to apply a current to the upper piezoelectric element group 450 when the body unit 400 is bent inside the display . Accordingly, each of the plurality of piezoelectric elements constituting the upper piezoelectric element group 450 may have a longer length. In this case, current may not be applied to the lower piezoelectric element group 470. The shape of the piezoelectric element constituting the lower piezoelectric element group 470 may not be deformed. Each of the plurality of piezoelectric elements constituting the upper piezoelectric element group 450 may have a longer length so as to have different curvatures.

The control unit 180 modifies the shapes of the body parts 210 and 400 in a shape corresponding to the identified application (S507). In one embodiment, the memory 170 included in the flexible watch type mobile terminal 200 may store the application and the deformation mode in association with each other. For example, the first application may correspond to the first deformation mode, and the second application may correspond to the second deformation mode. The deformation mode may be a mode in which the shape of the body part 210, 400 is deformed to a predetermined deformation state corresponding to the application. Specifically, the deformation mode may be a mode in which when the body part 210, 400 is detached from the frame part 230, the deformation mode is transformed into a predetermined shape according to the application being executed.
The control unit 180 may control the shape deforming units 300 and 440 to deform the body parts 210 and 400 in a shape corresponding to the application being executed.

The control unit 180 may detect this and transform the flexible display 251 so that the feeling of immersion is increased at the time of watching a moving picture as shown in FIG. 10B. Specifically, before the flexible display 251 is separated from the frame portion 230, the flexible display 251 has a constant curvature. That is, the flexible display 251 has a constant curvature and is in a bent state. When the flexible display 251 is separated from the frame unit 230, the control unit 180 can flex the flexible display 251 inward. The flexible display 251 may have a constant curvature so as to be bent in a direction opposite to that of FIG. 10A. This can be applied to the example in which the flexible display 251 is modified in Fig. 4C.
11A and 11B are views for explaining an example in which the flexible display is deformed as the flexible display is separated from the frame portion during the execution of the coupon service application.
Referring to FIG. 11A, the flexible display 251 and the frame unit 230 of the flexible watch type mobile terminal 200 are in a state of being stuck together. That is, the flexible watch type mobile terminal 200 may be worn on the user's wrist.
The flexible watch type mobile terminal 200 plays the flexible display 251 on the execution screen 1100 of the coupon service application. The coupon service application may be an application that provides coupons for product discount. In Fig. 11A, the flexible display 251 can display only coupons.
Referring to FIG. 11B, the flexible display 251 can be separated from the frame unit 230. The control unit 180 can detect this and modify the flexible display 251 to edit the coupon or have a suitable screen for detailed setting, as shown in FIG. 11B. Specifically, before the flexible display 251 is separated from the frame portion 230, the flexible display 251 has a constant curvature. When the flexible display 251 is separated from the frame unit 230, the control unit 180 can spread the flexible display 251 flat to have infinite curvature. That is, the shape of the flexible display 251 corresponding to the coupon service application may be a shape having an infinite curvature.
According to another embodiment of the present invention, an item corresponding to an application may be displayed while the shape of the flexible display 251 is modified based on a direction in which the flexible display 251 is separated from the frame portion 230. [
12 and 13 show an item corresponding to an application being executed while changing the shape of the flexible display 251 based on the direction in which the flexible display 251 is separated from the frame unit 230 according to the embodiment of the present invention Fig.
In particular, FIG. 12 shows a case where a message service application is running, and FIG. 13 shows a case where a camera application is running.
12, the user is wearing the flexible watch type mobile terminal 200 and the flexible display 251 is in a state before being separated from the frame part 230. [ The flexible display 251 is displayed on the execution screen 1200 of the message service application and is in a state of being fastened to the frame part 230 through the first fastening part 1210 and the second fastening part 1220. [ The execution screen 1200 of the message service application may include a message received from the counterpart terminal. Each fastening portion may be composed of a magnetic element, but this is merely an example. When the flexible display 251 is separated from the frame unit 230, the controller 180 can confirm whether the flexible display 251 is divided horizontally or vertically. For example, the control unit 180 can confirm the direction in which the flexible display 251 is separated through a sensing means such as a gyro sensor.
When the flexible display 251 is divided in the horizontal direction, the controller 180 can display the first type of keyboard input window 1230 while modifying the flexible display 251 to have an infinite curvature. The first type of keyboard input window 1230 may be a quarty keyboard.
When the flexible display 251 is separated in the vertical direction, the controller 180 can display the second type keyboard input window 1250 while modifying the flexible display 251 to have an infinite curvature. The second type of keyboard input window 1250 may be a hollow keyboard.
13, the user is wearing the flexible watch type mobile terminal 200 and the flexible display 251 is in a state before being separated from the frame part 230. [ The flexible display 251 is displaying the execution screen 1300 of the camera application and is in a state of being fastened to the frame part 230 through the first fastening part 1210 and the second fastening part 1220. [ The execution image 1200 of the camera application includes the image 1300 obtained through the camera 121. [ When the flexible display 251 is separated in the horizontal direction, the control unit 180 can change the shooting mode to the panoramic shooting mode while deforming the flexible display 251 to have an infinite curvature.
When the flexible display 251 is separated in the vertical direction, the control unit 180 can change the photographing mode to the landscape photographing mode while modifying the flexible display 251 to have an infinite curvature.
As such, by providing an item or mode corresponding to the direction in which the flexible display 251 is separated, an optimized service can be provided without additional operation of the user.
Although the present invention describes that the flexible display 251 is modified in a shape corresponding to the application being executed, the shape of the flexible display 251 may be modified according to the type of the media content being reproduced (or displayed). For example, when the flexible display 251 is disconnected while the moving picture is displayed before the flexible display 251 is separated, the control unit 180 transforms the flexible display 251 into a shape as shown in FIG. 10B . As another example, if the flexible display 251 is disconnected while the flexible display 251 is displaying a call request, a notification such as a message, a memo, or the like, the controller 180 controls the controller 180 May deform the flexible display 251 to have an infinite curvature.
