An antenna for receiving broadcast signals may be additionally disposed on the side surface of the main body 220. An antenna constituting a part of the broadcast receiving module 111 (see FIG. 1) may be installed to be able to be drawn out from the main body 220.

The main body 220 of the smart watch 200 may include a microphone (not shown), an interface, and the like. A user input unit 340 and a connection port may be disposed on the side surfaces of the front case 300 and the rear case 350.

The user input unit 340 is operated to receive a command for controlling the operation of the smart position 200 and may include at least one operation unit (not shown). The operating units may also be referred to as manipulating portions and may be employed in any manner as long as the user is operating in a tactile manner with a tactile impression.

Contents inputted by a plurality of operation units can be set variously. For example, inputting commands such as start, end, scroll, and the like, adjusting the size of the sound output from the sound output module 152, or switching the touch recognition mode of the display unit 151 have.

The connection port receives data from an external device or supplies power to each component in the smart watch 200 or allows data in the smart watch 200 to be transmitted to an external device. The connection port may be configured as an example of the interface 170 (see FIG. 1).

A main body 220 of the smart watch 200 is provided with a power supply unit (not shown) for supplying power to the smart watch 200. The power supply unit may be built in the main body 220.

In the following description, a method of changing a background image according to a wearing position of a wearable device 100, for example, a smart watch will be described in detail with reference to the drawings. The following description will be made on the assumption that only the main body 220 of the smart watch 200 according to the embodiment of the present invention is separated. However, this is for convenience of explanation, but is not limited thereto. That is, the present invention can be applied to a state where the 'body 210' is coupled to the 'body 220'.

4 is a flowchart illustrating a method of displaying a background image according to a wear position in a smart watch according to an exemplary embodiment of the present invention.

Referring to FIG. 4, the controller 180 recognizes the position where the main body is worn (S400). Here, the control unit 180 can recognize the position where the main body 200 is worn (or worn) when the main body 200 is detached (for example, the state of Fig. 5 (a)). The controller 180 may use various methods to recognize the position where the main body 220 is worn.

For example, the control unit 180 can recognize the position where the main body 220 is worn by using a groove for connecting various accessories. And a detection sensor (accessory detection unit) 142 for detecting the accessory is connected to the groove.

In this case, when the accessory is connected to the groove, the control unit 180 can sense the accessory connected through the accessory sensing unit 140. [ Also, information related to the accessory may be collected through various methods. For example, the accessory may be provided with means for transmitting its identification information to the main body 220 such as an NFC (Near Field Communication) tag or an RF (Radio Frequency) chip. In this case, the control unit 180 formed on the main body 220 can receive the identification information from the accessory through the wireless communication unit 110. [

Or the main body 220 may have a plurality of different grooves connected to each of the accessories. For example, the main body 220 may have a groove through which a hairpin support can be connected and a groove through which a pendant chain can be connected. In this case, the control unit 180 can identify which accessory is currently connected depending on which groove the accessory is connected to.

If it is identified which of the accessories is connected in this way, the control unit 180 can recognize which accessory is connected to itself. Then, the control unit 180 can recognize the position where the main body 220 is worn according to the connected accessories. For example, when the pendant chain is connected as an accessory, the control unit 180 can recognize that the body 220 can be used for the pendant use of the necklace in the forward direction so that the wear position of the body 220 is around the user's chest have.

Alternatively, the controller 180 may use the user's biometric signal to detect the wearing position of the main body 220. [ For example, the controller 180 may sense a user's heartbeat signal from the bio-signal sensor 352 disposed on the rear surface of the rear case 350. When the intensity of the heartbeat signal of the user is equal to or greater than a predetermined intensity, the controller 180 can recognize that the wear position of the main body 220 is around the user's chest. The closer the body 220 is to the user's chest, i.e. the heart, the stronger the heartbeat signal will be, and thus when the body 220 is used as a necklace pendant, the heartbeat signal is detected at a level above a certain level It is because.

When the wearing position of the main body 220 is recognized, the controller 180 searches the memory 160 for an image corresponding to the recognized wearing position. The display unit 151 is controlled so that the searched image is displayed as a background image of the display unit 151 (S402). Accordingly, when it is recognized that the body is worn around the user's chest in step S400, the controller 180 determines that the wear position is "on " from the images stored in the memory 160 to correspond to each of the predetermined plurality of wear positions, Quot; around the chest "and display it as a background image of the display unit 151. [0064] FIG.

5 (b) shows an example in which the main body 220 is used as a pendant of a necklace. For example, the control unit 180 may recognize that the pendant chain 500 is connected or recognize that the position where the main body 220 is worn by the user's biometric signal is around the user's chest. In this case, as shown in FIG. 5 (b), an image for using the main body 220 as a pendant may be displayed on the display unit 151 as a background image.

In addition, the controller 180 may recognize that the position where the main body 220 is worn is around the head of the user when the hair clip support 510 is connected as an accessory. The control unit 180 can recognize that the position where the main body 220 is worn is around the user's head using the intensity of the user's brain wave signal from the bio-signal sensor 352 disposed on the rear surface of the rear case 350 have. As the main body 220 is closer to the user's head, the intensity of the EEG signal will be stronger. Accordingly, when the main body 220 is used as a hair clipper, the intensity of the EEG signal can be detected to be higher than a certain level.

FIG. 5C is a diagram showing this example. 5C, when the body 220 is connected to the hairpin support 510, or when the intensity of the EEG signal sensed by the user is equal to or higher than a predetermined level, the controller 180 controls the operation of the body It can be recognized that the position is around the user's head. 5C, an image for using the main body 220 as a hair clip can be displayed on the display unit 151 as a background image.

The body 220 may also be used as a "pedometer" when connected to the waistband 520. For example, when connected to the waistband 520, the controller 180 may receive an identification signal from an NFC tag or an RF chip included in the waistband 520. The control unit 180 may recognize that the main body 220 is connected to the waistband 520 through the received identification signal. Or the control unit 180 may recognize that the body 220 is connected to the waistband 520 through the connection part when there is a separate connection part that can be connected to the waistband 520. [

When the main body 220 is connected to the waistband 520, the controller 180 can recognize that the main body 220 is worn around the waist of the user. In this case, the control unit 180 may control the display unit 151 such that an image for using the main body 220 is displayed as a background image with a "pedometer " as shown in Fig. 5 (d).

5 (b), (c), and (d), the controller 180 may collect information on connected accessories when the accessories are connected. Such information may be stored in the memory 160 or downloaded from an external server such as a cloud server through wireless communication.

Here, the information on the accessory may be information on the type, material, shape or color of the connected accessory. And such information about the accessories can be used to display background images in various forms.

6A and 6B are conceptual diagrams for explaining a method of identifying an accessory connected to the main body 220 and displaying a background image using the accessory.

The control unit 180 may display the image for allowing the main body 220 to be used as a clock as a background image on the display unit 151 when the wristband 230 is connected as an accessory. The control unit 180 may control the display unit 151 to display different images based on at least one of the type, shape, and color of the wristband 230 as a background image.

For example, as shown in FIG. 6A, in the case of the metal band 230a, the controller 180 may collect information about the band 230a. Here, the information on the band 230a may be collected through a process of receiving identification information from an NFC tag or an RF chip included in the band 230a, as described above.

The control unit 180 may search the memory 160 for an image corresponding to the identification information of the band 230a and may use the searched image as a background image of the display unit 151. [

Alternatively, the control unit 180 may change the background image displayed on the display unit 151 using the information collected about the band 230a. For example, the collected information may be information on the type, material, shape, or color of the band 230a, that is, information on the design of the band 230a. In this case, the control unit 180 may search an image similar to the design of the connected band 230a from the images stored in the memory 160 and display the retrieved image as a background image on the display unit 151. [ Figure 6 (b) shows this example.

It goes without saying that this can be applied not only to metal bands but also to denim band forms. 6 (a) and 6 (b) show this example.

6B, when the denim band 230b is connected to the main body 220, the controller 180 determines whether identification information or band 230b received from the band 230b is mounted The band 230b can be identified through a hole or the like. The control unit 180 may search the memory 160 for an image corresponding to the identification result of the band 230b and display the retrieved image on the display unit 151 as a background image.

Alternatively, the control unit 180 may change the background image displayed on the display unit 151 using the information collected about the band 230b, as shown in FIG. 6B. That is, the control unit 180 may collect information about the design of the band 230b, display an image similar to the band 230b from the memory 160, and display the retrieved image as a background image on the display unit 151 have.

6A and 6B, it is described that the control unit 180 receives the identification information from the bands 230a and 230b or identifies the bands 230a and 230b using the holes in which the bands 230a and 230b are mounted , But it is also possible to identify the bands 230a and 230b in a different manner.

For example, the controller 180 may use a separate sensor such as an infrared sensor or an ultrasonic sensor to identify the bands 230a and 230b. In this case, it is needless to say that the controller 180 may identify the bands 230a and 230b using the diffraction time of the ultrasonic wave or the infrared ray.

6A and 6B, it is assumed that the information about the bands 230a and 230b is collected through the memory 160 or the external server. Alternatively, the bands 230a and 230b Of course, information can also be collected. For example, the control unit 180 may receive images of the bands 230a and 230b through the camera 121 or a camera (not shown) provided separately. The control unit 180 can retrieve a design similar to the received image from the memory 160 and display it as a background image. Alternatively, the control unit 180 may display the image itself received from the camera as a background image.

It should be noted that the smart watch 200 according to the embodiment of the present invention may be used for a purpose corresponding to a place where the user is currently located. For example, the main body 220 of the smart watch 200 may be used for an ID (Identification) card containing identification information of a user depending on where the user is located, or may be used as a support item.

Figures 7a and 7b illustrate this example.

For example, when the user enters the workplace of the user, the main body 220 can recognize that the place where the user is currently located is the workplace through the NFC tag or the RF chip installed in the workplace. The controller 180 may display on the display unit 151 an image for using the main body 220 as a user's ID card as a background image. Accordingly, the display unit 151 may display an image including identification information of the user.

In addition, the control unit 180 may determine a background image to be displayed on the display unit 151 using not only a place where the user is located but also a position where the main body 220 is worn. For example, the control unit 180 can identify the place where the user is currently located and retrieve the images of the place corresponding to the place from the memory 160. The control unit 180 recognizes the position where the main body 220 is worn and displays any one of the searched images corresponding to the position where the main body 220 is worn according to the recognition result, (151). Here, it is a matter of course that a plurality of images corresponding to at least one wearing position are stored in advance in the memory 160 according to a plurality of predetermined places.

Accordingly, if the place where the current user is located is the workplace of the user and the user wears the main body 220 on the chest, the control unit 180 displays an image 700 for using the main body as a user's ID badge May be displayed on the display unit 151 as a background image. FIG. 7A shows an example in which the body of the smart watch 200 is used as a user's ID badge.

Similarly, the smart watch 200 according to the embodiment of the present invention can also be used as a supporting piece. For example, when the user is present at a place such as a concert venue or an athletic venue as a result of the user's current position determination, the controller 180 recognizes the background image and displays a background image for using the main body 220 as a supporting props, 151).

That is, when the user enters the concert field or the athletic field, the controller 180 can recognize the current user's location through an information transmitting means such as an NFC tag or an RF chip installed in the concert field or the sports field. Or the location information module 115 and the pre-stored degree of navigation.

In this case, the control unit 180 may collect information about the performance contents or sports game contents of the current concert hall through the information transmission means. For example, when the user goes to a concert hall of a specific singer, or when a specific singer performs a performance, the control unit 180 can receive such information from a concert hall or an information transmitting means provided inside the athletic arena. The control unit 180 selects an image to be displayed as a background image on the display unit 151 based on the received information.

Here, the information received from the information transmitting means installed in the concert field or the sports field may include information on at least one image. For example, if the user's current location is a concert venue, a cheer image may be included for a particular singer performing in the concert. Or if the current position of the user is an athletic field, the support image for the team corresponding to the user's support position may be included.

The control unit 180 may display the image received from the information transmitting means on the display unit 151 as a background image. Alternatively, the control unit 180 may store the cheering images to be used as background images in advance in the memory 160, and may display at least one image corresponding to the information received from the information transmitting means as the background image on the display unit 151 It can also be displayed.

FIG. 7B shows an example in which a cheering image is displayed as a background image according to a place where a user is currently located. 7B, when the user enters a concert hall of a specific artist group, the controller 180 receives information including the support image 750 from information transmission means provided in the concert hall can do. The control unit 180 may control the display unit 151 to display the support image 750 as a background image. Accordingly, the body 220 of the smart watch 200 according to the embodiment of the present invention can be used as various support tools depending on the place where the user is currently located.

Also, it is needless to say that different background images may be displayed on the display unit 151 depending on the position where the main body 220 is worn, even when used as a cheering tool.

For example, as shown in FIG. 7B (b), the body 220 of the smart watch 200 according to an embodiment of the present invention may be used as a "support rod ". In other words, the control unit 180 can detect when the main body 220 is connected to the bar, and display the image for using the main body 220 as a "support rope" as a background image on the display unit 151 .

Here, the control unit 180 may select at least one of the images included in the information received from the information transmission means installed in the concert field or the sports venue, and display the display unit 151 of the main body 220 mounted on the " As a background image. Or the image preset by the user may be displayed on the display unit 151 as a background image.

In the above-described embodiment, the controller 180 has been stored in the memory 160 or used as an image downloaded from an external server or an information transmitting means disposed in a specific place. However, It is also possible to use an image corresponding to at least a part of the entire screen of the external device capable of communicating with the external device 220 as the background image.

8A and 8B are views showing this example.

In the case of an external device capable of communicating with the main body 220, for example, a mobile terminal, an image displayed on the entire display screen of the external device according to the user's selection may be displayed on a display portion (not shown) of the smart watch 200 according to the embodiment of the present invention 151 as background images.

8A, when the main body 220 is contacted with at least a part of the display unit 802 of the mobile terminal 800, the controller 180 controls the wireless communication with the mobile terminal 800 Can be performed. Then, the control unit 180 can receive the image 804 currently used as the background image from the mobile terminal 800. The control unit 180 may display the received image 804 on the display unit 151 as a background image as shown in (b) of FIG. 8A.

The controller 180 of the smart watch 200 according to the embodiment of the present invention may receive not only the entire background image but also a part of the background image from the mobile terminal 800. [

8B, in a state in which the background image 850 is displayed on the display unit 802 of the mobile terminal 800 as shown in FIG. 8B, the smart watch 801 according to the embodiment of the present invention The control unit 180 may perform wireless communication with the mobile terminal 800 when the main body 220 of the mobile terminal 200 is contacted.

8B, when the main body 220 is brought into contact with one region of the display portion 802, the controller 180 controls the background image corresponding to the region in which the main body 220 is contacted, From the mobile terminal 800, a partial image 860 of the image 850.

For example, when the main body 220 contacts the display unit 802, the control unit of the mobile terminal 800 may generate a new image of the area of the background image 850 corresponding to the contacted area. Or the control unit 180 of the mobile terminal 800 detects a point where the center of the main body 220 contacts the display unit 802 and detects an area of the corresponding background image 850 within a certain distance from the detected point You can create a new image.

The generated image may be transmitted from the mobile terminal 800 to the main body 220. Then, the control unit 180 may control the display unit 151 to display the image received from the mobile terminal 800 as a background image.

Therefore, when the background image 850 is an image for a specific person, as shown in Fig. 8 (a), an area where the body 220 is contacted as shown in Fig. 8 (b) The area corresponding to the area in which the main body 220 is contacted, that is, the area of the face of the specific character 220, An image 860 corresponding to the portion of the image can be displayed as a background image on the display portion 151 of the main body 220. [

In the above description, it is assumed that the external device is a mobile terminal, but it is needless to say that the external device is not limited to a mobile terminal. That is, it is possible to communicate with the smart watch 200 according to the embodiment of the present invention, and when the display unit is provided, it can be any of the external devices described above.

In the above description, the body 220 of the smart watch 200 according to the embodiment of the present invention is detected when the body 220 is worn on one of the body parts of the user. However, It may be used for various purposes.

 Hereinafter, a method which can be used for various purposes according to the wearing position even if not worn on the user's body will be described in detail with reference to the drawings.

9 is a conceptual diagram for explaining a method of using a smart watch according to an embodiment of the present invention for another purpose.

For example, as shown in FIG. 9A, the body 220 of the smart watch 200 according to the embodiment of the present invention can also be used as a key of an electronic lock. That is, when the main body 220 is connected to the lock 900 or is connected to the lock 900 through wireless communication or the like, the controller 180 can detect the lock 900. In this case, the control unit 180 may act as a key of the lock 900 in various ways.

For example, the main body 220 of the smart watch 200 according to the embodiment of the present invention can use the fingerprint recognition of the user as shown in FIG. 9 (b). That is, when a fingerprint is input from the touch screen, the controller 180 compares the inputted fingerprint with previously stored fingerprint images, and determines whether the fingerprint currently input is a fingerprint of the user who is allowed to unlock the lock 900 Or not. If the unlocking of the lock is determined to be the fingerprint of the authorized user, the control unit 180 may transmit a control signal to the lock 900 to unlock the lock 900. [ The lock 900 may then be unlocked in response to the received control signal.

In addition to the fingerprint recognition method, the body 220 of the smart watch 200 according to the embodiment of the present invention can act as a key of the lock 900 in various ways. For example, the main body 220 may perform such a key function through pattern recognition or recognition of the user's facial structure.

Figures 9 (b) and 9 (c) show this example. For example, in the case of FIG. 9 (b), the controller 180 may determine whether or not an unlock signal is transmitted to the lock 900 according to whether the pattern set by the user matches the predetermined input pattern.

9 (c), the image of the user's face is captured from the built-in camera 121, and the captured image is analyzed to determine whether or not the user is allowed to unlock the lock . The control unit 180 may transmit an unlock signal to the lock 900 based on the determination result.

As described above, the smart watch 200 according to the embodiment of the present invention can act as a key of the electronic lock when it is worn on the electronic lock. However, it is needless to say that the present invention can be used for various purposes.

Further, in the embodiment of the present invention, when the wear position is around the user's head, around the chest, or around the waist, it is recognized that a background image corresponding to each wearing position is displayed on the display unit 151. However, It is needless to say that the present invention can be applied to a case where it is worn on a part other than the above-mentioned part.

Further, according to the embodiment disclosed herein, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RaM, cd-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the embodiments disclosed in the present invention are not intended to limit the scope of the present invention but to limit the scope of the technical idea of the present invention.
