When the display unit 251 is implemented as a touch screen, the display unit 251 may serve as the user input unit 223, and thus, a separate key may not be provided in the main body 201.

The band 202 may be formed to be wearable on a wrist and surround the wrist, and be formed of a flexible material for wearing easiness. For example, the band 202 may be formed of leather, rubber, silicon, a synthetic resin, and the like. Further, the band 202 is detachably formed in the main body 201, so that a user may replace various types of bands according to his/her taste.

In some implementations, the band 202 may be used to expand performance of the antenna. For example, a ground expansion unit (not illustrated), which is electrically connected with the antenna to expand a ground field, may be embedded in the band.

The band 202 may be provided with a fastener 202a. The fastener 202a may be implemented by a buckle, a hook structure enabling snap-fit, or Velcro™, and include an elastic section or material. FIG. 4A illustrates an example in which the fastener 202a is implemented in a buckle type.

FIG. 4B is a perspective view illustrating an example of a glasses-type wearable device (e.g., glasses-type device 200b).

Referring to the example of FIG. 4B, the glasses-type wearable device 200b may be configured to be wearable on a head of a human body, and include a frame unit (a case, a housing, and the like) for the wearing. The frame unit may be formed of a flexible material for easy wearing. FIG. 4B illustrates an example in which the frame unit includes a first frame 206 and a second frame 207 having different materials.

The frame units 206 and 207 are supported by the head, and provide spaces for mounting various components. As illustrated in FIG. 4B, an electronic component, such as a control unit 280 and a sound output module 142 may be mounted in the frame units 206 and 207. Further, a lens 208 covering at least one of a left eye and a right eye may be detachably mounted in the frame unit.

The control unit 280 controls various electronic components included in the wearable device 200b. FIG. 4B illustrates an example in which the control unit 280 is installed in the frame unit at one side of the head. However, a location of the control unit 280 is not limited thereto.

The display unit 251 may be implemented in a form of a head mounted display (HMD). The HMD form refers to a display method, in which a display is mounted on a head to directly display an image in front of the eyes of a user. When a user wears the glasses-type wearable device 200b, the display unit 251 may be disposed so as to correspond to at least one of a left eye and a right eye so as to directly provide an image to the front side of the eyes of the user. FIG. 4B illustrates an example in which the display unit 251 is located at a part corresponding to the right eye so as to output an image toward the right eye of the user.

The display unit 251 may project an image onto the eyes of the user by using a prism. Further, the prism may be light-transmissively formed so as to enable a user to view the projected image and a general view at a front side (a range viewed through the eyes of the user) together.

Accordingly, the image output through the display unit 251 may be displayed while overlapping a general view. The wearable device 200b may provide augmented reality (AR), in which a real image or background overlaps a virtual image, so that one image is displayed by using the characteristic of the display.

The camera 221 is disposed to be adjacent to at least one of the left eye and the right eye to photograph an image at a front side. The camera 221 is located to be adjacent to the eyes, so that the camera 221 may obtain a scene viewed by a user as an image.

The camera 221 may also be installed in the frame unit, and a plurality of cameras 221 may be provided to obtain a 3D image.

The glasses-type wearable device 200b may include user input units 223a and 223b manipulated so as to receive a control command. As long as a manner is a tactile manner performing a manipulation while detecting a tactile feeling, such as a touch or a push, of a user, the user input units 223a and 223b may adopt any type. FIG. 4B illustrates an example in which the user input unit 223a by the push input manner and the user input unit 223b by the touch input manner are provided in the frame unit and the control unit 280, respectively.

Further, the glasses-type wearable device 220b may include a microphone (not illustrated) for receiving a sound and processing the received sound into electrical voice data, and a sound output module 252 for outputting a sound. The sound output module 252 may be configured to transmit a sound by a general sound output manner or a bone conduction manner. In a case where the sound output module 252 is implemented by the bone conduction manner, when a user wears the wearable device 200b, the sound output module 252 is in close contact with a head, and vibrates a skull and transmits a sound.

FIG. 5 is a block diagram of an example of a wearable device.

In the example of FIG. 5, the wearable device 200 may include a wireless communication unit 210, an input unit 220, a sensing unit 240, an output unit 250, an interface unit 260, a memory 270, a control unit 280, a power supply unit 290, and the like.

For example, the wireless communication unit 210 among the constituent elements may include one or more modules capable of establishing wireless communication between the wearable device 200 and a wireless communication system, between the wearable device 200 and another device (for example, a mobile terminal or a wearable device), or the wearable device 200 and an external server. Further, the wireless communication unit 210 may include one or more modules for connecting the wearable device 200 to one or more networks.

The wireless communication unit 210 may include one or more of a broadcast receiving module 211, a mobile communication module 212, a wireless Internet module 213, a short range communication module 214, or a location information module 215.

The broadcast receiving module 211 receives a broadcast signal and/or broadcast related information from an external broadcast management server through a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel.

The mobile communication module 212 transceives a wireless signal with at least one of a base station, an external terminal, and a server on a mobile communication network established according to technical standards or a communication manner for mobile communication (for example, global system for mobile communication (GSM), code division multi access (CDMA), code division multi access 2000 (CDMA2000), enhanced voice-data optimized or enhanced voice-data only (EV-DO), wideband CDMA (WCDMA), high speed downlink packet access (HSDPA), high speed uplink packet access (HSUPA), long term evolution (LTE), and long term evolution-advanced (LTE-A)).

The wireless signal may include various types of data according to transception of a voice call signal, a video call signal, or a character/multimedia message.

The wireless Internet module 213 refers to a module for wireless Internet connection, and may be mounted inside or outside the wearable device 200. The wireless Internet module 213 is configured to transceive a wireless signal on a communication network according to suitable wireless Internet technologies.

From the point of view that the wireless Internet connection by WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A, and the like are established through a mobile communication network, the wireless Internet module 213 may, in some implementations, perform wireless Internet connection through the mobile communication network and therefore function as mobile communication module 212.

The short range communication module 214 is used for short range communication, and may support short range communication by using at least one of Bluetooth™, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, near field communication (NFC), Wi-Fi, Wi-Fi Direct, and/or wireless universal serial bus (wireless USB) technologies. The short range communication module 214 may support wireless communication between the wearable device 200 and a wireless communication system, between the wearable device 200 and another wearable device 200, or the wearable device 200 and a network on which another wearable device 200 (or an external server) is located, through a short range wireless communication network (wireless area network). The short range wireless communication network may be a short range wireless personal network (e.g., a wireless personal area network).

The location information module 215 is a module used for obtaining a location (or a current location) of the wearable device, and a representative example thereof includes a GPS module or a Wi-Fi module. For example, when the wearable device utilizes a GPS module, it is possible to obtain a location of the wearable device by using a signal transmitted by a GPS satellite. As another example, when the wearable device utilizes a Wi-Fi module, it is possible to obtain a location of the wearable device based on information about a wireless Access Point (AP) transmitting or receiving a wireless signal with the Wi-Fi module. Alternately or additionally, the location information module 215 may perform a specific function of another module of the wireless communication unit 210 in order to obtain data on a location of the wearable device as necessary. The location information module 215 is a module used for obtaining a location (or a current location) of the wearable device, and is not limited to a module which directly calculates or obtains a location of the wearable device.

The input unit 220 may include a camera 221 or an image input unit for inputting an image signal, a microphone 222 or an audio input unit for inputting an audio signal, and a user input unit 223 (for example, a touch key and a push key (mechanical key)) for receiving an input of information from a user. Voice data or image data collected by the input unit 220 may be analyzed and processed by a control command of the user.

The camera 221 processes an image frame, such as a still image or a moving image, obtained by an image sensor in a video call mode or a photography mode. The processed image frame may be displayed on the display unit 251 or stored in the memory 270. In some implementations, the plurality of cameras 221 provided in the wearable device 200 may be disposed in a matrix structure, and a plurality of elements of image information having various angles and focuses may be input into the wearable device 200 through the cameras 221 having the matrix structure. Further, the plurality of cameras 221 may be disposed in a stereo structure so as to obtain a left image and a right image for implementing a 3D image.

The microphone 222 processes an external sound signal into electrical voice data. The processed voice data may be variously utilized according to a function (or a currently executed application program) performed (e.g., concurrently) by the wearable device 200. In some implementations, various noise removing algorithms for removing a noise generated during a process of receiving an input of an external sound signal may be implemented in the microphone 222.

The user input unit 223 is used for receiving an input of information from the user, and when information is input through the user input unit 223, the control unit 280 may control an operation of the wearable device 200 so as to correspond to the input information. The user input unit 223 may include a mechanical input means (or a mechanical key, for example, a button, a dome switch, a jog wheel, and a jog switch positioned on a front and/or rear surface or a lateral surface of the wearable device 200) and/or a touch-type input means. For example, the touch type input means may be formed of a virtual key, a soft key, or a visual key displayed on a touch screen through software processing, or a touch key disposed at a part other than the touch screen, and the virtual key or the visual key may be displayed on the touch screen with various forms, and formed by, for example, graphic, text, an icon, a video, or a combination thereof.

The sensing unit 240 may include one or more sensors for sensing at least one element of wearable device-inside information, information about a surrounding environment surrounding the wearable device, and user information. For example, the sensing unit 240 may include at least one of a wearing detecting unit 241, a proximity sensor, an illumination sensor, a touch sensor, an acceleration sensor, a magnetic sensor, a gravity-sensor (G-sensor), a gyroscope sensor, a motion sensor, an RGB sensor, an infrared sensor (IR sensor), a finger scan sensor, an ultrasonic sensor, an optical sensor (for example, see the camera 221), a microphone (see the microphone 222), a battery gauge, an environment sensor (for example, a barometer, a hygrometer, a thermometer, a radioactivity detecting sensor, a thermal detecting sensor, and a gas detecting sensor), and a chemical sensor (for example, an electronic nose, a healthcare sensor, and a biometric sensor). In some implementations, the wearable device may combine information sensed by two or more sensors among the sensors and utilize the combined information.

The control unit 280 may control driving or an operation of the wearable device 200 based on the sensing signal, or perform data processing, a function, or an operation related to an application program installed in the wearable device 200.

Hereinafter, representative sensors among the various sensors includable in the sensing unit 240 will be described in more detail.

The wearing detecting unit 241 may detect whether the user of the wearable device 200 is wearing the wearable device 200. The wearing detecting unit 241 may detect whether the user is wearing the wearable device 200 by using any one of the proximity sensor, the illumination sensor, the touch sensor, the motion sensor, the IR sensor, and the ultrasonic sensor.

The proximity sensor refers to a sensor for detecting whether an object approaching a predetermined detection surface or an object existing at the vicinity exists by using force of an electromagnetic field or infrared rays without a mechanical contact. The proximity sensor may be disposed in an internal area of the wearable device surrounded by the aforementioned touch screen or around the touch screen.

Examples of the proximity sensor include a transmissive optical electric sensor, a direct reflective optical electric sensor, a mirror reflective optical electric sensor, a high-frequency oscillation-type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an IR proximity sensor. When the touch screen is a capacitive type, the proximity sensor may be configured to detect approach of an object based on a change in an electric field according to approach of a conductive object. In this case, the touch screen (or the touch sensor) itself may be divided into the proximity sensor.

For convenience of description, an action in which an object approaches the touch screen while not being in contact with the touch screen, so that the object is recognized to be located on the touch screen, is referred to as “a proximity touch,” and an action in which an object is actually in contact with the touch screen is referred to as “a contact touch.” The position at which the object is proximity-touched on the touch screen refers to a position at which the object vertically corresponds to the touch screen when the object is proximity-touched. The proximity sensor may detect 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, or a proximity touch movement state). In some implementations, the control unit 280 may process data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected by the proximity sensor, and further, output visual information corresponding to processed data on the touch screen. Further, the control unit 280 may control the wearable device 200 so that different operations or data (or information) are processed according to whether the touch at the same point on the touch screen is a proximity touch or a contact touch.

The touch sensor detects a touch (or a touch input) applied to the touch screen (or the display unit 251) by using at least one of various touch methods, such as a resistive method, a capacitive method, an IR method, an ultrasonic method, and/or a magnetic method.

As an example, the touch sensor may be configured to convert a change in a pressure applied to a specific region of the touch screen, a capacitance and the like generated at a specific region, or the like into an electrical input signal. The touch sensor may be configured to detect a position and an area, in which a touch object applying a touch onto the touch screen is touched, on the touch sensor, a pressure during the touch, capacitance during the touch, and the like. Here, the touch object is an object applying a touch to the touch sensor, for example, a finger, a touch pen, a stylus pen, and a pointer.

As described above, when a touch input is generated in the touch sensor, a signal(s) corresponding to the touch input is transmitted to a touch controller. The touch controller processes the signal(s), and then transmits corresponding data to the control unit 280. Accordingly, the control unit 280 may recognize a region of the display unit 251, in which the touch is made. Here, the touch controller may be a separate constituent element from the control unit 280, or be the control unit 280 itself.

In some implementations, the control unit 280 may perform different controls or the same control according to the kinds of touch objects touching the touch screen (or a touch key provided other than the touch screen). Whether to perform different controls or the same control according to the kinds of touch objects may be determined according to a current operation state of the wearable device 200 or a currently executed application program.

The touch sensor and the proximity sensor, which have been described above, may sense various kinds of touches, such as a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swype touch, and/or a hovering touch, to the touch screen independently or in combination.

The ultrasonic sensor may recognize location information about a detection target by using ultrasonic waves. In some implementations, the control unit 280 may calculate a location of a wave generating source based on information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave generating source may be calculated by using a property that light is much faster than ultrasonic waves, that is, a time, for which light reaches the optical sensor, is much shorter than a time, for which ultrasonic waves reach the ultrasonic sensor. For example, it may be possible to calculate the position of the wave generating source by using a difference in reaching time between light as a reference signal and ultrasonic waves.

In some implementations, the camera 221, which has been described as the constituent element of the input unit 220, includes at least one of a camera sensor (for example, a CCD and a CMOS), a photo sensor (or an image sensor), and a laser sensor.

The camera 221 and the laser sensor may be combined with each other to detect a touch of a detection target to a 3D image. The photo sensor may be stacked on the display device, and the photo sensor is configured to scan a movement of a detection target approaching the touch screen. More particularly, the photo sensor, in which photo diodes and transistors (TR) are mounted in rows and columns, scans contents put on the photo sensor by using an electric signal changed according to a quantity of light applied to the photo diode. For example, the photo sensor may calculate coordinates of the detection target according to a variation amount of light, and obtain location information about the detection target through the calculated coordinates.

The output unit 250 generates an output related to a sense of sight, a sense of hearing, or a sense of touch, and may include at least one of the display unit 251, the sound output unit 252, a haptic module 253, and an optical output unit 254. The display unit 251 may be formed in a layer structure with the touch sensor or be integrally formed with the touch sensor to implement the touch screen. The touch screen may serve as the user input unit 223 providing an input interface between the wearable device 200 and the user, and provide an output interface between the wearable device 200 and the user.

The display unit 251 may display or otherwise output information processed by the wearable device 200. For example, the display unit 251 may display execution image information about an application program driven by the wearable device 200, or user interface (UI) and graphic user interface (GUI) information according to the execution image information. Further, the display unit 251 may be configured as a 3D display unit displaying a 3D image.

A 3D display method, such as a stereoscopic method (glasses method), an auto stereoscopic method (glassless method), and a projection method (holographic method, may be applied to the 3D display unit.

The sound output unit 252 may output audio data received from the wireless communication unit 210 in call signal reception mode, a call mode, a recording mode, a voice recognition mode, and a broadcast reception mode, or stored in the memory 270. The sound output unit 252 may also output a sound signal related to a function (for example, a call signal reception sound and a message reception sound) performed by the wearable device 200. The sound output unit 252 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 253 generates various tactile effects felt by the user. A representative example of the tactile effect generated by the haptic module 253 may be a vibration. Intensity, a pattern, and the like of the vibration generated by the haptic module 253 may be controlled by a selection of the user or setting of the control unit. For example, the haptic module 253 may combine different vibrations and output the combined vibrations, or sequentially output different vibrations.

The haptic module 253 may generate various tactile effects, such as an effect by injection force or suction force of air through a pin arrangement vertically moving with respect to a contact skin surface, an injection hole, or a suction hole, brush against a surface of skin, a contact of an electrode, and an effect by stimulation of electromagnetic force, and an effect by reproduction of thermal feedback by using a heat absorbing or heating device, in addition to vibrations.

The haptic module 253 may also be implemented to deliver a tactile effect through a direct contact, and make the user feel a tactile effect through kinesthesia of a finger, an arm, and the like. Two or more haptic modules 253 may be provided according to the configuration of the wearable device 200.

The interface unit 260 serves as a passage for various kinds of external devices connected to the wearable device 200. The interface unit 260 may include at least one of a wire/wireless headset port, an external charger port, a wire/wireless data port, a memory card port, a port for connecting a device provided with an identification module, an audio input/output (I/O) port, a video input/output (I/O) port, and an earphone port. The wearable device 200 may perform an appropriate control related to a connected external device in response to the connection of the external device to the interface unit 260.

In some implementations, the identification module is a chip storing various pieces of information for identifying use authorization of the wearable device 200, and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM). The device provided with the identification module (hereinafter, the “identification device”) may be manufactured by a smart card type. Accordingly, the identification device may be connected with the terminal 200 through the interface unit 260.

Further, the interface unit 260 may be a passage through which power from a cradle is supplied to the wearable device 200, or a passage through which various command signals input from the cradles by the user are transmitted to the wearable device 200 when the wearable device 200 is connected with the external cradle. The various command signals or the power input from the cradle may be operated as signals for recognizing that the wearable device 200 is accurately mounted in the cradle.

The memory 270 stores data supporting various functions of the wearable device 200. The memory 270 may store a plurality of application programs (or applications) driven by the wearable device 200, and data and commands for operating the wearable device 200. At least some of the application programs may be downloaded from an external server through wireless communication. Further, at least some of the application programs may exist in the wearable device 200 from a release time for a basic function (for example, a call receiving and sending function and a message receiving and sending function) of the wearable device 200. In the meantime, the application program may be stored in the memory 270, and installed in the wearable device 200 to be driven to perform the operation (or function) of the wearable device 200 by the control unit 280.

The memory 270 may temporarily store input/output data (for example, a phone book, messages, still images, and moving images). The memory 270 may store data about various patterns of vibration and sound output when a touch is input into the touch screen.

The memory 270 may include at least one type of storage medium among a flash memory type, a hard disk type, a solid state disk (SSD) type, a silicon disk drive (SDD) type, a multimedia card micro type, a card-type memory (for example, an SD or XD memory), a random access memory (RAM), a static random access (SRAM) memory, a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and/or an optical disk. The wearable device 200 may be operated in association with a web storage which performs a storage function of the memory 270 on the Internet.

The control unit 280 generally controls operations of the wearable device 200, in addition to operations related to the application program. The control unit 280 may provide or process appropriate information or functions to the user by processing a signal, data, information, and the like input or output through the aforementioned constituent elements, or driving an application program stored in the memory 270.

Further, the control unit 280 may control at least some of the constituent elements in order to drive an application program stored in the memory 270. Further, the control unit 280 may combine and operate two or more of the constituent elements included in the wearable device 200 in order to drive the application program.

The power supply unit 290 receives external power and internal power and supplies power to each constituent element included in the wearable device 200 under the control of the control unit 280. The power supply unit 290 includes a battery, and the battery may be an embedded battery or a replaceable battery.

Further, the power supply unit 290 may include a connection port, and the connection port may be configured as one example of the interface 260 electrically connected with an external charger, which supplies power for charging the battery.

As another example, the power supply unit 290 may be configured to charge the battery in a wireless manner without using the connection port.

At least some of the constituent elements may be cooperatively operated in order to implement the operation, the control, or the control method of the wearable device according to some implementations which are to be described below. Further, the operation, the control, or the control method of the wearable device may be implemented on the wearable device by driving one or more application programs stored in the memory 270.

In some implementations, techniques may be implemented in a recording medium readable by a computer or a device similar to the computer by using, for example, software, hardware, or a combination thereof.

In some cases, each constituent element of the mobile terminal 300 may be described based on the constituent element of the aforementioned wearable device.

FIG. 6 is a flowchart of an example of operations of a vehicle and a wearable device according to a first implementation.

In the first example implementation of FIG. 6, the wearable device 200 may be linked with the vehicle 100 in a state of not being connected with the mobile terminal 300 (for example, a smart phone).

First, an operation of the vehicle 100 according to the first implementation will be described with reference to FIG. 6.

The control unit 180 of the vehicle 100 performs pairing with the wearable device 200 through the short range communication module 113 (S605).

For example, when a user wearing the previously registered wearable device 200 gets in the vehicle 100, the control unit 180 of the vehicle 100 performs identification on the wearable device 200, and then performs pairing with the wearable device 200 by using a short range communication manner. In this case, the short range communication manner may adopt the Bluetooth manner, but may use at least one of radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, near field communication (NFC), Wi-Fi, Wi-Fi direct, and/or wireless universal serial bus (wireless USB).

After the pairing with the wearable device 200, the control unit 180 of the vehicle 100 determines whether the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200 (S610). The control unit 180 of the vehicle 100 may determine whether the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200 through the interface unit 170.

When the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200, the control unit of the vehicle 100 provides electric energy to the wearable device 200 through the interface unit 170 (S615). In this case, the electric energy is for charging the wearable device 200.

Then, the control unit 180 of the vehicle 100 is connected to a mobile communication network through the wearable device 200 (S620).

The wearable device 200 may be connected to the mobile communication network through the mobile communication module 212 (see FIG. 5). Here, the mobile communication network is a network using any one mobile communication manner among global system for mobile communication (GSM), code division multi access (CDMA), code division multi access 2000 (CDMA2000), enhanced voice-data optimized or enhanced voice-data only (EV-DO), wideband CDMA (WCDMA), high speed downlink packet access (HSDPA), high speed uplink packet access (HSUPA), long term evolution (LTE), and long term evolution-advanced (LTE-A).

In some implementations, when a communication module for the connection to the mobile communication network is not provided in the vehicle 100, and the vehicle 100 is electrically connected to the wearable device 200, the control unit 180 of the vehicle 100 may be connected to the mobile communication network through the mobile communication module 212 (see FIG. 5) included in the wearable device 200.

In the state of being connected to the mobile communication network, the control unit 180 of the vehicle 100 may output information received in the wearable device 200 (S625). For example, the control unit 180 of the vehicle 100 may receive the information received in the wearable device 200 from the wearable device 200 through the interface unit 170 (see FIG. 3), and output the received information through the output unit 140.

Here, the information received in the wearable device 200 may be call reception information or text/multimedia message reception information received from a device of a counterpart connecting to the mobile communication network.

For example, when a call is received in the wearable device 200 in a state where the control unit 180 of the vehicle 100 is connected to the mobile communication network, the control unit 180 of the vehicle 100 may output call reception information to any one of the display unit 141, the sound output unit 142, and the haptic output unit 143. Then, when a user input for a phone call is received through the input unit 120, the control unit 180 of the vehicle 100 may perform a voice input and output operation by controlling the microphone 123 and the sound output unit 142 so that the user may have a phone call with a counterpart.

As another example, when a text message is received in the wearable device 200 in a state where the control unit 180 of the vehicle 100 is connected to the mobile communication network, the control unit 180 of the vehicle 100 may output the received text message through the display unit 141. As another example, the control unit 180 of the vehicle 100 may text-to-speech (TTS) convert the received text message into speech and output the speech in a form of a voice through the sound output unit 142. Then, the control unit 180 of the vehicle 100 may receive a voice input of a passenger through the microphone 123, speech-to-text (STT) convert the received voice input into text, and transmit the text to a device of a counterpart.

In some implementations, the control unit 180 of the vehicle 100 may receive driving assistance information (for example, navigation information, road information, accident information, and emergency rescue information) or infotainment service (for example, Internet, TV program contents, a movie, and a game) from an external server through the mobile communication network. In this case, the display unit 141 and the sound output unit 142 may function as a telematics device by using the wearable device 200.

The control unit 180 of the vehicle 100 may establish a short range wireless communication network through the short range communication module 113 in the state of being connected to the mobile communication network (S630). Here, the short range wireless communication network may be a network to which a plurality of devices may be connected by using the short range communication manner. Further, the short range wireless communication network may be connected with the mobile communication network. Here, the short range wireless communication network may use the Wi-Fi manner, but may use at least one of Bluetooth™, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, near field communication (NFC), Wi-Fi, Wi-Fi direct, and wireless universal serial bus (wireless USB) technologies.

Then, the control unit 180 of the vehicle 100 determines whether the connection with the wearable device 200 is released (S635), and when the connection with the wearable device 200 is not released, performs operations of S615 to S630.

In some implementations, when the user of the wearable device 200 releases a wearing state of the wearable device 200 in a state of getting in the vehicle 100, the control unit 180 of the vehicle 100 may receive information on a non-wearing state. Here, the determination whether the user of the wearable device 200 gets in the vehicle 100 may be performed based on whether the vehicle 100 and the wearable device 200 are connected through the short range wireless communication.

For example, when the wearing detecting unit 241 of the wearable device 200 may detect whether the user wears the wearable device 200, and the control unit 180 of the vehicle 100 may receive information about whether the user wears the wearable device 200.

When the control unit 180 of the vehicle 100 is not electrically connected with the wearable device 200 in the non-wearing state in operation S610, the control unit 180 of the vehicle 100 outputs a message for checking charging through the output unit 140 (S640). The output of the message for checking charging has an effect in that when the wearable device 200 is not connected with the control unit 180 of the vehicle 100 even though the user of the wearable device 200 releases the wearing state for the electrical connection with the vehicle 100, the user may recognize the disconnection.

In some implementations, the control unit 180 of the vehicle 100 may perform identification on a passenger possessing the wearable device 200 before being paired with the wearable device 200 (S605) or being electrically connected with the wearable device 200 (S610).

The biometric information detecting unit 131 (see FIG. 3) may detect biometric information about a passenger. The control unit 180 of the vehicle 100 may be matched with the wearable device and compare first biometric information about a user of the wearable device stored in the memory 160 (see FIG. 3) and second biometric information about the passenger detected through the biometric information detecting unit.

When the first biometric information is matched with the second biometric information, the passenger is identified, and the control unit 180 of the vehicle 100 may be connected with the wearable device 200 through the short range wireless communication (S605) or electrically connected with the wearable device 200 (S610).

When the first biometric information is not matched with the second biometric information, so that the passenger is not identified, the control unit 180 of the vehicle 100 is not connected with the wearable device 200 through the short range wireless communication (S605) and is not electrically connected with the wearable device 200 (S610).

Next, an operation of the wearable device 200 according to the first implementation will be described with reference to FIG. 6.

The control unit 280 of the wearable device 200 performs pairing with the vehicle 100 through the short range communication module 213 (S655).

For example, when a user wearing the wearable device 200 gets in the previously registered vehicle 100, the control unit 280 of the wearable device 200 performs identification on the vehicle 100, and performs pairing with the vehicle 100 by using the short range communication manner. Here, the short range communication network may adopt the Bluetooth™ manner, but may use at least one of radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, near field communication (NFC), Wi-Fi, Wi-Fi direct, and wireless universal serial bus (wireless USB) technologies.

The control unit 280 of the wearable device 200 may determine whether the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100 (S660). For example, the control unit 280 of the wearable device 200 may determine whether the control unit 280 of the wearable device 200 is connected with the vehicle 100 through the interface unit 260.

When the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100, the control unit 280 of the wearable device 200 receives electric energy from the vehicle 100 through the interface unit 260, and is charged by using the received electric energy (S665).

The wearable device 200 is connected to the mobile communication network through the mobile communication module 212 (see FIG. 5) (S670). In the present example, it is described that the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100, and then is connected to the mobile communication network (S670), but the wearable device 200 may always be connected to the mobile communication network in a state where a power supply of the wearable device 200 is turned on.

The control unit 280 of the wearable device 200 receives predetermined information through the mobile communication network in a state of being connected to the mobile communication network, and transmits the received information to the vehicle 100 through the interface unit 260 (see FIG. 5) (S675). Here, the received information may be call reception information or text/multimedia message reception information received from a device of a counterpart connected to the mobile communication network.

Then, the control unit 280 of the wearable device 200 determines whether the connection with the vehicle 100 is released (S680), and when the connection with the vehicle 100 is not released, operations of S665 to S675 are performed.

In some implementations, when the user of the wearable device 200 is in a state of getting in the vehicle 100, and the wearable device 200 is in a non-wearing state and is not electrically connected with the vehicle 100, the control unit 280 of the wearable device 200 may transmit information on a non-wearing state to the vehicle 100 (S685). Here, the determination whether the user of the wearable device 200 gets in the vehicle 100 may be performed based on whether the vehicle 100 and the wearable device 200 are connected through the short range wireless communication. Here, the information on the non-wearing state may be obtained by the wearing detecting unit 241.

FIG. 7 is a flowchart of an example of operations of a vehicle and a wearable device according to a second implementation.

In the example second implementation of FIG. 7, a user may get in the vehicle 100 in a state where the wearable device 200 is connected with the mobile terminal 300 (for example, a smart phone). Hereinafter, the second implementation will be described according to differences from the first implementation that was illustrated in FIG. 6. Unless specifically mentioned, contents described in the example first implementation of FIG. 6 may also be applied to the second implementation of FIG. 7.

First, an example of an operation of the vehicle 100 according to the second implementation will be described with reference to FIG. 7.

The control unit 180 of the vehicle 100 receives information on a wearing state of the wearable device 200 from the wearable device 200 (S701). For example, when a user wears the wearable device 200, the control unit 180 of the vehicle 100 receives information on a wearing state of the wearable device 200. When the user does not wear the wearable device 200, the control unit 180 of the vehicle 100 receives information on a non-wearing state. Here, information on the wearing state or the non-wearing state may be received in a form of a beacon signal before the vehicle 100 is paired with the wearable device 200.

After the information on the wearing state or the non-wearing state is received, the control unit 180 of the vehicle 100 receives an input for selecting any one of the wearable device 200 and the mobile terminal 300 (S703). For example, the control unit 180 of the vehicle 100 displays a selection input image for selecting one of the wearable device and the mobile terminal to be first paired on the display unit 141, and receives a user input through the selection input image, and selects any one of the wearable device 200 and the mobile terminal 300.

When the wearable device 200 is selected, the control unit 180 of the vehicle 100 performs pairing with the wearable device 200 (S705).

After being paired with the wearable device 200, the control unit 180 of the vehicle 100 determines whether the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200 (S707).

When the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200, the control unit 180 of the vehicle 100 provides electric energy to the wearable device 200 through the interface unit 170 (S709).

Then, the control unit 180 of the vehicle 100 is connected to the mobile communication network through the wearable device 200 (S711).

In the state of being connected to the mobile communication network, the control unit 180 of the vehicle 100 may output information received in the wearable device 200 (S713).

In the state of being connected to the mobile communication network, the control unit 180 of the vehicle 100 may establish a short range wireless communication network through the short range communication module 113 (S715).

Then, the control unit 180 of the vehicle 100 determines whether the connection with the wearable device 200 is released (S717), and when the connection with the wearable device 200 is not released, operations of S709 to S715 are performed.

When the mobile terminal 300 is selected in operation S703, the control unit 180 of the vehicle 100 performs pairing with the mobile terminal 300 (S719).

When the control unit 180 of the vehicle 100 is paired with the mobile terminal 300, the control unit 180 of the vehicle 100 may output information received in the mobile terminal 300 (S721). For example, the control unit 180 of the vehicle 100 may receive the information received in the mobile terminal 300 from the mobile terminal 300 through the interface unit 170 (see FIG. 3), and output the received information through the output unit 140.

Here, the information received in the mobile terminal 300 may be call reception information or text/multimedia message reception information received from a device of a counterpart accessing the mobile communication network.

In some implementations, although not illustrated, similar to the case where the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200, when the control unit 180 of the vehicle 100 is electrically connected with the mobile terminal 300, the control unit 180 of the vehicle 100 may be connected to the mobile communication network through the mobile terminal 300. Further, the control unit 180 of the vehicle 100 may also establish a short range wireless communication network through the short range communication module 113.

When the user of the wearable device 200 gets in the vehicle 100, and the wearable device 200 is in the non-wearing state, and the control unit 180 of the vehicle 100 is not electrically connected with the wearable device 200 in operation S707, the control unit 180 of the vehicle 100 may output a message for checking charging through the output unit 140 (S723).

Next, an example of an operation of the wearable device 200 according to the second implementation will be described with reference to FIG. 7.

The wearable device 200 performs pairing with the mobile terminal 300 (S731).

In a state of being paired with the mobile terminal 300, the control unit 280 of the wearable device 200 may receive information stored in the mobile terminal 300 (S732). For example, in a state of being connected with the mobile terminal 300 through short range wireless communication, the control unit 280 of the wearable device 200 may receive alarm or schedule information stored in the mobile terminal 300.

In the state of being connected with the mobile terminal 300 through short range wireless communication, the control unit 280 of the wearable device 200 determines whether the user wears the wearable device 200 (S733). The control unit 280 of the wearable device 200 may determine whether the user wears the wearable device 200 based on sensing data of the wearing detecting unit 241.

When the wearable device 200 is in the non-wearing state, the control unit 280 of the wearable device 200 performs pairing with the vehicle 100 (S735).

After being paired with the vehicle 100, the control unit 280 of the wearable device 200 determines whether the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100 (S737).

When the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100, the control unit 280 of the wearable device 200 transmits information on an electrical connection state with the vehicle 100 to the mobile terminal 300.

Then, the control unit 280 of the wearable device 200 releases the pairing with the mobile terminal 300 (S741).

When the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100, the control unit 280 of the wearable device 200 receives electric energy from the vehicle 100 through the interface unit 260, and is charged by using the received electric energy (SS743).

The wearable device 200 is connected to the mobile communication network through the mobile communication module 212 (see FIG. 5) (S747). In the present example, it is described that the control unit 280 of the wearable device 200 is electrically connected with the vehicle 100, and then is connected to the mobile communication network (S670), but the wearable device 200 may always be connected to the mobile communication network in a state where a power supply of the wearable device 200 is turned on.

The control unit 280 of the wearable device 200 receives predetermined information through the mobile communication network in a state of being connected to the mobile communication network, and transmits the received information to the vehicle 100 through the interface unit 260 (see FIG. 5) (S749).

Then, the control unit 280 of the wearable device 200 determines whether the connection with the vehicle 100 is released (S751), and when the connection with the vehicle 100 is not released, operations of S743 to S749 are performed.

When it is determined that the user wears the wearable device 200 in operation 733, the control unit 280 of the wearable device 200 may transmit information on a wearing state to at least one of the vehicle 100 and the mobile terminal 300 (S753).

In some implementations, when the user of the wearable device 200 gets in the vehicle 100, and the wearable device 200 is in a non-wearing state and is not electrically connected with the vehicle 100 in operation S737, the control unit 280 of the wearable device 200 may transmit information on a non-wearing state to the vehicle 100 (S755).

Next, an operation of the mobile terminal 300 according to the second implementation will be described with reference to FIG. 7.

The mobile terminal 300 is connected with the wearable device 200 through the short range wireless communication. In the state of being connected through the short range wireless communication, the mobile terminal 300 may transmit information stored in the memory of the mobile terminal 300 to the wearable device 200. Here, the information stored in the memory may be alarm or schedule information.

The mobile terminal 300 may receive the information on the wearing state from the wearable device 200.

When the mobile terminal 300 receives information on a connection state with the vehicle 100 from the wearable device 200, the mobile terminal 300 may change a notification method (S775). For example, when the mobile terminal 300 receives the information on the connection state with the vehicle 100 from the wearable device 200 in a state where the notification method of the mobile terminal 300 is set to be silent, the mobile terminal 300 may change the notification method to a sound or a vibration.

When the user of the wearable device 200 gets in the vehicle 100, and the wearable device 200 is in the non-wearing state, and is not electrically connected with the vehicle 100, the mobile terminal 300 may output a message for checking charging of the wearable device 200 (S777).

When the mobile terminal 300 is paired with the vehicle 100 (S781), the mobile terminal 300 transmits information received in the mobile terminal 300 to the vehicle 100 through the mobile communication network (S783).

FIGS. 8 to 14 are diagrams illustrating examples of an operation of the vehicle when the vehicle and the wearable device are electrically connected.

FIG. 8 illustrates an example of a message displayed on the display unit 141 of the vehicle 100 when the vehicle 100 and the wearable device 200 are electrically connected.

As illustrated in the example of FIG. 8, the vehicle 100 may include the interface unit 170 in a predetermined region of the center fascia. Here, the interface unit 170 serves as a passage for various kinds of external devices connected to the vehicle 100, and may include a holding part and a connection part. The holding part includes a holding means (for example, a form of a hole, a drawer, and a shelf) on which an external device may be held. The connection part includes a connection means (for example, a connection pin and a connection port) through which an external device may be connected.

When the vehicle 100 is electrically connected with the interface unit 260 of the wearable device 200 through the connection part, the control unit 180 of the vehicle 100 provides electric energy to the wearable device 200. The wearable device 200 performs charging based on the electric energy provided from the vehicle 100. In this case, the control unit 180 of the vehicle 100 displays charge status information of the wearable device 200 on the display unit 141.

FIG. 9 is a diagram illustrating an example of an operation in which the vehicle 100 is connected to a mobile communication network through the wearable device 200.

Referring to the example of FIG. 9, when the control unit 180 of the vehicle 100 is electrically connected with the wearable device 200, the control unit 180 of the vehicle 100 is connected to a mobile communication network 910 through the wearable device 200. Here, the mobile communication network is a network using any one mobile communication manner among global system for mobile communication (GSM), code division multi access (CDMA), code division multi access 2000 (CDMA2000), enhanced voice-data optimized or enhanced voice-data only (EV-DO), wideband CDMA (WCDMA), high speed downlink packet access (HSDPA), high speed uplink packet access (HSUPA), long term evolution (LTE), and/or long term evolution-advanced (LTE-A).

When a communication module for the access to the mobile communication network is not provided in the vehicle 100, and the vehicle 100 is electrically connected to the wearable device 200, the control unit 180 of the vehicle 100 may be connected to the mobile communication network through the mobile communication module 212 (see FIG. 5) included in the wearable device 200.

The control unit 180 of the vehicle 100 may exchange data while communicating with at least one of another vehicle 420, an external server 410, a counterpart mobile terminal 920, and a counterpart wearable device 930 through the mobile communication network 910.

For example, the control unit 180 of the vehicle 100 may receive traffic information collected by another vehicle 420 by communicating with another vehicle 420 through the mobile communication network 910.

For example, the control unit 180 of the vehicle 100 may receive driving assistant information (for example, navigation information, road information, accident information, and emergency rescue information) or infotainment service (for example, the Internet, TV program contents, movies, and games) by communicating with the external server 410 through the mobile communication network 910.

As another example, the control unit 180 of the vehicle 100 may control so that the call reception information is output in a form of a voice through the sound output unit 142.

Next, the control unit 180 of the vehicle 100 may receive a user input for a call connection through the input unit 120. Then, when the user input for the call connection is received, the control unit 180 of the vehicle 100 may perform a voice input and output operation by controlling the microphone 123 and the sound output unit 142 so that the user may have a phone call with the counterpart terminal 920 (see FIG. 9).

As illustrated in the example of FIG. 10B, a text message is received in the wearable device 200 from the counterpart terminal 920 (see FIG. 9) in the state where the control unit 180 of the vehicle 100 is connected to the mobile communication network 910 (see FIG. 9) through the wearable device 200, the control unit 180 of the vehicle 100 may output the received text message through the display unit 141. As another example, the control unit 180 of the vehicle 100 may TTS-convert the received text message into speech and output the speech in a form of a voice through the sound output unit 142.

Next, the control unit 180 of the vehicle 100 may receive a user input for transmitting a text message (reply) through the input unit 120. For example, the control unit 180 of the vehicle 100 may receive the user input through a touch input for the display unit 141 or a voice input through the microphone 123. When the voice input through the microphone 123 is received, the control unit 180 of the vehicle 100 STT-converts the received voice input into text, and then transmits the text to the counterpart terminal 920 (see FIG. 9).

FIGS. 11 to 13 are diagrams of examples of an operation of receiving information from an external server (e.g., the external server 410) (see FIG. 9) and displaying the received information.

The control unit 180 of the vehicle 100 may be connected to the external server 410 (see FIG. 9) in a state of being connected to the mobile communication network 910 (see FIG. 9) through the wearable device 200. Here, the external server may be a traffic information providing server or a weather information providing server. The control unit 180 of the vehicle 100 may receive various pieces of information from the external server 410 (see FIG. 9) and output the received information.

For example, the control unit 180 of the vehicle 100 detects biometric information about a passenger through the biometric information detecting unit 131. The control unit 180 of the vehicle 100 may be matched with the wearable device 200 and compare first biometric information about a user of the wearable device stored in the memory 160 (see FIG. 3) and second biometric information about the passenger detected through the biometric information detecting unit 131.

When the first biometric information is matched with the second biometric information, the passenger is identified, and the control unit 180 of the vehicle 100 may be connected with the wearable device 200 through the short range wireless communication or electrically connected with the wearable device 200.

When the first biometric information is not matched with the second biometric information, so that the passenger is not identified, the control unit 180 of the vehicle 100 is not connected with the wearable device 200 through the short range wireless communication and is not electrically connected with the wearable device 200.

FIG. 15 illustrates the fingerprint scanner 131 as an example of the biometric information detecting unit 131, but implementations are not limited thereto, and the vehicle 100 may include an iris scanner or a retina scanner and obtain iris scan information or retina scan information about a passenger. In some cases, the biometric information detecting unit 131 may include the camera 122 and obtain hand geometry information and facial recognition information about a passenger. As another example, the biometric information detecting unit 131 may include the microphone 123 to obtain voice recognition information about a passenger.

FIG. 16 is a diagram of an example of an operation of a vehicle when a user does not wear a wearable device.

Referring to the example of FIG. 16, when the control unit 180 of the vehicle 100 is not electrically connected with the wearable device 200 in the non-wearing state, the control unit 180 of the vehicle 100 may display a message for checking charging through the display unit 141. Further, the control unit 180 of the vehicle 100 may output the message for checking charging through the sound output unit 142 in a form of a voice.

As described above, the output of the message for checking charging has an effect in that when the wearable device 200 is not connected with the control unit 180 of the vehicle 100 even though the user of the wearable device 200 releases the wearing state for the electrical connection with the vehicle 100, the user may recognize the disconnection.

In some implementations, the information on the wearing state may be detected by the wearing detecting unit 241 included in the wearable device 200. The control unit 180 of the vehicle 100 may receive the information on the detected wearing state.

FIGS. 17 to 20 are diagrams of examples of an operation of a vehicle in which a passenger of the vehicle possesses both a wearable device and a mobile terminal.

As illustrated in the example of FIG. 17, the control unit 180 of the vehicle 100 receives information on a wearing state of the wearable device 200 from the wearable device 200. For example, when the user wears the wearable device 200, the control unit 180 of the vehicle 100 receives the information on the wearing state. When the user does not wear the wearable device 200, the control unit 180 of the vehicle 100 receives information on a non-wearing state. Here, the information on the wearing state or the non-wearing state may be received in a form of a beacon signal before the vehicle 100 is paired with the wearable device 200.

After the information on the wearing state or the non-wearing state is received, the control unit 180 of the vehicle 100 displays a selection input image 1710 for selecting one of the wearable device 200 and the mobile terminal 300 to be first paired on the display unit 141.

When the selection input for the mobile terminal 1720 or the wearable device 1730 is received, the control unit 180 of the vehicle 100 performs pairing with the selected device.

In some implementations, the pairing may also be performed according to a preset priority. In a case where it is set that the control unit 180 of the vehicle 100 is paired with the wearable device 200 in the wearing state with a top priority, when receiving the information on the wearing state, the control unit 180 of the vehicle 100 performs a pairing operation with the wearable device 1730. In a case where it is set that the control unit 180 of the vehicle 100 is paired with the mobile terminal 300 in the non-wearing state as a top priority, when receiving the information on the non-wearing state, the control unit 180 of the vehicle 100 performs the pairing operation with the mobile terminal 300.

As illustrated in the example of FIG. 18, when the wearable device 200 is electrically connected with the vehicle 100 in a state where the wearable device 200 is paired with the mobile terminal 300, the control unit 280 of the wearable device 200 transmits information on an electrical connection state with the vehicle 100 to the mobile terminal 300.

In this case, the mobile terminal 300 may change a notification method.

For example, when the user takes the wearable device in a state where the notification method of the mobile terminal 300 is set to be silent and the user recognizes the notification of the mobile terminal 300 through the wearable device 200, the user cannot recognize the notification of the mobile terminal 300. Accordingly, when the wearable device 200 is electrically connected with the vehicle 100 and the notification method of the mobile terminal 300 is changed from silent to a vibration or a sound, there is an effect in that the user may recognize the notification of the mobile terminal 300.

As illustrated in the example of FIG. 19, when the wearable device 200 is electrically connected with the vehicle 100 in a state where the wearable device 200 is paired with the mobile terminal 300, information stored in the mobile terminal 300 may be output through the wearable device 200. For example, when a schedule or an alarm is set and stored in the mobile terminal, the schedule or the alarm 1910 may be output through the output unit 250 of the wearable device 200.

As illustrated in the example of FIG. 20, when the wearable device 200 is electrically connected with the vehicle 100 in a state where the wearable device 200 is paired with the mobile terminal 300, information received in the mobile terminal 300 through the mobile communication network may be output through the vehicle 100. For example, when a call is received in the mobile terminal 300 through the mobile communication network, call reception information 2010 may be displayed through the display unit 141 of the vehicle 100 or output through the sound output unit 142.

As described above, in the state where the wearable device 200 is electrically connected with the vehicle 100, information, which the user may need to immediately recognize, is output through the vehicle 100, and information, which the user may not need to immediately recognize, is output through the wearable device 200, so that there is an effect in that a quantity of information recognized by the user while driving is decreased, thereby helping the user to safely drive.
