Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

[ The audio output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 153 may be vibration. The intensity and pattern of the vibration generated in the haptic module 153 can be controlled by the user's selection or the setting of the control unit. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output the vibrations.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

2 is a flowchart of a method of controlling a mobile terminal according to an embodiment of the present invention. 3 is a flowchart of a method for an occupant to output content related to an occupant when boarding a vehicle according to an embodiment of the present invention. FIGS. 4 to 8 are diagrams for explaining outputting contents related to an occupant when a passenger boarding a vehicle according to an embodiment of the present invention. FIG.

The method for controlling a mobile terminal according to an embodiment of the present invention may be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the control unit 180 may receive at least one of the sensing information or the operation information obtained from the vehicle from the communication unit of the vehicle (S100).

Referring to Figure 4 (a), a portion of the interior of the vehicle 300 is shown. According to an example, the mobile terminal 100 may be a portable device including a camera 121 such as a smart phone, which is mounted on one area of the vehicle 300 when a passenger boarded the vehicle 300.

However, the present invention is not limited thereto. According to another example, an electronic device capable of recognizing the face of a passenger through a camera can be included in the mobile terminal. For example, the mobile terminal may be an electronic device provided in the vehicle 300, such as a black box 100_1 including a camera 121_1 or a navigation device. Alternatively, the mobile terminal may be a display device 100_2 including a camera 121_2 and a display unit 151_2 provided behind the headrest of the front seat of the vehicle 300, as shown in FIG. 4B .

Hereinafter, for convenience of explanation, it is assumed that the mobile terminal is a portable device. However, the following description can be applied substantially equally to electronic equipments provided in the vehicle 300, except when it is not applicable. Alternatively, in the case where the control unit of the portable device operates in conjunction with the control unit of the electronic device provided in the vehicle 300 according to another example, the following description is substantially the same Lt; / RTI >

The control unit 180 may perform a communication connection with the communication unit of the vehicle 300 through the wireless communication unit 110 when the mobile terminal 100 approaches the vehicle 300 within a predetermined distance. For example, when the mobile terminal 100 enters the interior of the vehicle 300, the control unit 180 may perform a communication connection with the communication unit of the vehicle 300. [ The communication connection can be performed according to the wireless communication method described with reference to FIG. 1, and is not limited to a specific method.

According to one example, the vehicle 300 is provided with a communication unit for communicating with an external device, an input unit for receiving an input of a passenger to the vehicle 300, an indoor status of a passenger, an indoor status of the vehicle, And a sensing unit for sensing the signal. Various devices included in the communication unit, the input unit, the sensing unit, and other vehicles may be controlled by a control unit of the vehicle 300.

The control unit of the vehicle 300 may transmit the sensing information or the operation information obtained at the sensing unit of the vehicle 300 or the like to the wireless communication unit 110 of the mobile terminal 100 when the control unit of the vehicle 300 is communicatively connected to the mobile terminal 100. [ The control unit 180 of the mobile terminal 100 may receive the sensing information or the operation information through the wireless communication unit 110. [

According to an example, the sensing information may include boarding information of the occupant or room condition information of the vehicle. In addition, the operation information may include driving information of the vehicle or operation information of an electronic device provided in the vehicle. However, the present invention is not limited thereto. It will be appreciated that the sensing information and the operation information may further include other information as needed.

Referring back to FIG. 2, the controller 180 may determine whether an event to perform face recognition of a passenger is generated (S110).

The event for performing the face recognition of the passenger may mean an event requiring the face recognition of the occupant in order for the control unit 180 of the mobile terminal 100 to perform an operation suitable for the occupant. For example, the occupant boarding the vehicle 300 may be an event that causes the controller 180 to perform the face recognition of the occupant in order to output contents suitable for the occupant's state.

The control unit 180 may determine whether an event to perform face recognition of the occupant is generated based on the sensing information or the operation information received from the vehicle 300. [ According to an example, a database for the event may be stored in the memory 170 of the mobile terminal 100. The database may include information on events corresponding to specific sensing information or operation information, respectively.

The control unit 180 may read the database from the memory 170 upon receiving the sensing information or the operation information from the vehicle 300. [ The control unit 180 compares the sensed information or the operation information stored corresponding to each event in the database with the received sensing information or operation information to determine whether a specific event has occurred.

If the received sensing information or operation information does not correspond to the event stored in the database [S110, No], the control unit 180 may receive sensing information or operation information from the vehicle 300 again.

Referring to FIG. 2 again, the control unit 180 may perform face recognition of the passenger through the image obtained through the camera when the event is generated (S120).

Referring to FIG. 5, the control unit 180 of the mobile terminal 100 may drive the camera 121 when an event to perform face recognition of the occupant occurs (S110, Yes). The control unit 180 can acquire the image of the passenger P1 through the camera 121. [

As shown in Fig. 6, the control unit 180 can extract the face image of the occupant P1 from the obtained image i1. The control unit 180 can analyze the face image of the extracted passenger P1 to identify the passenger P1. According to one example, in order to identify the occupant P1, the face image of a plurality of passengers may be stored in the memory 170 corresponding to the identification information. The control unit 180 can identify the passenger P1 by comparing the face image of the passengers stored in the memory 170 with the extracted face image.

Also, the control unit 180 can recognize the facial expression of the passenger P1 by analyzing the extracted facial image of the passenger P1. According to an example, the controller 180 can recognize the facial expression of the user by analyzing the contours of the eyes e1 and e2 and the mouth m among the faces of the extracted occupant P1. The control unit 180 can obtain the emotion state information or the like of the occupant P1 on the basis of the recognized facial expression. However, the present invention is not limited thereto. Any facial recognition method can be applied as long as the extracted facial image can be analyzed to acquire information such as an emotional state.

Referring back to FIG. 2, the controller 180 may perform an operation corresponding to the event based on the result of the face recognition (S130).

According to an example, the database for the event stored in the memory 170 may store an operation set corresponding to a face recognition result of the user for each event. When the result of the face recognition is obtained, the control unit 180 can confirm and perform an operation corresponding to the event generated in the database and the result of the obtained face recognition. For example, an operation performed by the control unit 180 when an event that a passenger boarded the vehicle P1 occurs will be described below.

Referring to FIG. 3, the control unit 180 may receive the sensing information obtained from the vehicle from the communication unit of the vehicle (S200).

When the passenger is boarded on the vehicle 300, the sensing unit of the vehicle 300 can detect whether or not the passenger is boarding the passenger. The sensing information obtained at the sensing unit of the vehicle 300 may be transmitted to the mobile terminal 100 through the communication unit of the vehicle 300. [ According to an example, whether or not the passenger is boarding can be detected by a weight detection sensor provided in the seat of the vehicle 300. [ However, the present invention is not limited thereto. Various sensors can be used as long as it is possible to detect whether or not the vehicle is occupied.

Referring again to FIG. 3, the control unit 180 may determine whether an event to perform face recognition of the occupant is generated based on the occupant's boarding information (S210).

When the control unit 180 receives the boarding information as the sensing information from the vehicle 300, the control unit 180 can read the database from the memory 170. The control unit 180 may determine whether the boarding information of the passenger in the database matches the sensing information corresponding to the event. When the boarding information of the passenger is stored in the database as the sensing information corresponding to the event, the controller 180 can determine that the event has occurred.

Referring to FIG. 3, the control unit 180 may recognize the face of the passenger through the image obtained through the camera when the event is generated (S220).

The control unit 180 can extract the face image of the passenger P1 from the obtained image i1. The control unit 180 can analyze the face image of the extracted passenger P1 to identify the passenger P1. Since the identification of the passenger P1 has been described above, a detailed description thereof will be omitted.

Referring again to FIG. 3, the controller 180 may output content related to the identified passenger according to the face recognition (S230).

The control unit 180 can read the boarding event of the passenger and the contents information stored corresponding to the identified passenger in the database for the event stored in the memory 170. [ For example, when the identified passenger is 'Jane', the boarding party's boarding event and the content information stored in response to 'Jane' can be read.

According to an example, the content information may be a music file most recently played by a passenger while driving. For this, the control unit 180 can update the database using the information about the music file that was being played when the passenger finishes driving.

Referring to FIG. 7, if 'Jane' is identified while 'Jane' is boarded, the controller 180 can reproduce the music file most recently played during 'Jane' running. The control unit 180 may provide the notification 10 that the music file that is played most recently during 'Jane' running on the touch screen 151 of the mobile terminal 100 is played.

According to an example, it is assumed that the event for performing the face recognition of the occupant is the execution of the driver's seat of the specific occupant and the navigation application. When a specific passenger (for example, 'Jane') is boarded on the driver's seat and the navigation application is executed, the control unit 180 can output information on the route that the identified specific passenger traveled.

For example, it is assumed that 'Jane' parked at a specific location and stored information is stored in the database. The control unit 180 can confirm whether it is close to the specific position while performing the navigation guidance. If it is close to the specific position, the control unit 180 may provide the notification (11) that the identified occupant 'Jane' recently visited the specific location as shown in FIG.

According to this, when a specific event occurs, it is possible to provide a preset operation based on the occupant's face recognition result. Further, it is possible to provide contents suitable for the passenger while driving by carrying out recognition of the occupant's face based on the sensing information or the operation information obtained in the vehicle.

In the above description, it is determined that the event is generated based on the sensing information or the operation information received from the communication unit of the vehicle 300. However, the present invention is not limited thereto. According to an example, the controller 180 may determine whether the event is generated by using the information obtained from the mobile terminal 100, in addition to the sensing information or the operation information.

For this, the mobile terminal 100 may further include a sensing unit 140 or an input unit 120. The control unit 180 may determine whether the event is generated based on the information input through the sensing unit 140 or the input unit 120. [

According to an example, the control unit 180 may determine whether the event is generated through an image acquired by the camera 121 included in the input unit 120. [ Alternatively, the control unit 180 may determine whether the event is generated based on sound data such as a laughter sound obtained in the microphone 122 included in the input unit 120.

According to an example, the controller 180 may determine whether the event is generated based on the temperature information sensed by the temperature sensor included in the sensing unit 140. [ Alternatively, the control unit 180 may determine whether the event is generated based on the brightness information detected by the brightness sensor 122 included in the sensing unit 140. [

However, the configuration included in the input unit 120 or the sensing unit 140 is one example, but is not limited thereto. The control unit 180 may determine whether the event is generated based on the information received from the various components included in the input unit 120 or the sensing unit 140.

According to this, it is possible to provide contents suitable for the state in the vehicle by performing face recognition based on the information input through the sensing unit or the input unit.

9 is a flowchart of a method of storing contents based on a face recognition result of a passenger performed during outputting of contents according to an embodiment of the present invention. FIGS. 10 to 15 are diagrams for explaining how content is stored or shared based on a result of face recognition of a passenger performed during outputting of contents according to an embodiment of the present invention.

A method of storing contents based on a result of face recognition performed by the occupant during the outputting of contents according to an embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 9, the control unit 180 may receive the operation information obtained from the vehicle from the communication unit of the vehicle (S300).

Referring to FIG. 10, an audio reproducing apparatus 310 may be provided in the vehicle 300 according to an example. The control unit of the vehicle 300 may obtain the operation information on whether the music file is reproduced in the audio reproduction device 310. [ The obtained operation information may be transmitted to the mobile terminal 100 through the communication unit of the vehicle 300. [

However, the present invention is not limited thereto. The present invention can be applied to any electronic apparatus provided in a vehicle other than the audio reproduction apparatus 310 and capable of reproducing contents. In addition, the content may include various multimedia files such as images and moving pictures in addition to music files.

Referring again to FIG. 9, the control unit 180 determines whether an event to perform face recognition of the occupant is generated based on whether the contents of the electronic device provided in the vehicle are output from the operation information (S310) , The face recognition of the occupant can be performed [S320].

The control unit 180 can read the database from the memory 170 upon receiving the reproduction information of the music file as the operation information from the vehicle 300. [ If the playback information of the music file is stored in the database as operation information corresponding to the event, the controller 180 may determine that the event has occurred.

The control unit 180 can recognize the face of the passenger through the image obtained through the camera 121 when the event is generated. The control unit 180 can recognize the facial expression of the passenger P1 by analyzing the face image of the occupant P1 extracted from the obtained image i1 as shown in Fig.

According to an example, the controller 180 can recognize the facial expression of the passenger by analyzing the contours of the eyes e1 and e2 and the mouth m among the faces of the extracted occupant P1. The control unit 180 can obtain the emotion state information or the like of the occupant P1 on the basis of the recognized facial expression. For example, referring to Fig. 11, both eyes e1 and e2 of the passenger P1 and the contour of the mouth m may be judged to be pleasant to the occupant P1.

Referring again to FIG. 9, the controller 180 may determine whether the recognized facial expression of the occupant meets a predetermined condition (S330).

According to one example, the predetermined condition to be compared with the expression of the occupant may be stored in the database. The predetermined condition may be an image of a face corresponding to various emotion states of the occupant. For example, if the image of the expression in which the outlines of the passengers' eyes e1 and e2 fall below a predetermined value or the outline of the mouth m goes above a predetermined value or more, Lt; / RTI >

The control unit 180 can confirm an image of a facial expression matching the facial expression of the acquired occupant among the facial images stored in the database. If there is an image of matching facial expression, the control unit 180 can determine the emotion of the occupant corresponding to the image of the matched facial expression as the current emotional state of the occupant.

Referring to FIG. 9, the controller 180 may acquire information about the content currently being output from the vehicle 300 when the expression of the passenger meets the predetermined condition (S340).

According to an example, the predetermined condition may further include a condition for storing content currently being output in a specific emotion state. For example, as shown in FIG. 10, if the expression of the occupant is recognized as pleasant while the music file is being reproduced, a condition for storing the music file currently being played may be further set.

The control unit 180 may receive information on the music file being output from the audio player 310 from the control unit of the vehicle 300. According to an example, the information on the music file may be the music file itself or the identification information of the music file. If only the identification information of the music file is received, the control unit 180 can acquire the music file on the communication network through the wireless communication unit 110. [

Referring again to FIG. 9, the controller 180 may classify the acquired content into categories corresponding to the facial expression of the occupant and store the classified contents (S350).

Referring to FIG. 12, the controller 180 may store the acquired music file in the memory 170 based on the occupant's current emotional state. For example, if the occupant is presently in a pleasant state, the control unit 180 generates a folder 20 of a category indicating 'Jane', which is the emotional state of the occupant and the identified occupant 'Jane', and stores the music file . Alternatively, if a folder having a category indicating 'Jane' and 'happy state' has already been created, the control unit 180 can search the corresponding folder and store the music file.

According to an example, when the running of the vehicle 300 is terminated, the control unit 180 may display a folder in which the music file meeting the predetermined condition is stored, as shown in FIG. The control unit 180 may display a notification 21 that the music file is stored while driving.

The operation of storing the contents described in Fig. 9 can be repeatedly performed when the predetermined condition is satisfied while the vehicle 300 is running. According to an example, the controller 180 may perform the operation when the content output from the vehicle 300 is changed.

According to an example, after the content of the music file or the like is stored, the same passenger may be boarded on the vehicle 300 again. The control unit 180 may perform face recognition of the occupant when an event for outputting content is generated. If there is content previously stored in advance for the identified passenger, the control unit 180 may output the content stored in the category corresponding to the expression of the passenger.

According to an example, the control unit 180 may perform a navigation function to a destination input during driving of the vehicle 300. The passenger can get off the destination and acquire an image using the mobile terminal 100. [ Referring to FIG. 13, the passenger can select the photographing button (c) as the preview image pi obtained by the camera 121 and acquire the image as an image.

In this case, the control unit 180 may store the acquired image in association with the content stored during driving to the destination. Referring to FIG. 14, the controller 180 may generate a folder 30 for storing images obtained at the destination. The control unit 180 may display a notification 31 asking whether to store the acquired image in association with the music file stored during the driving. When the obtained image is stored in association with the music file, the controller 180 can reproduce the music file in a predetermined order when the folder 30 is displayed.

According to an example, the controller 180 may identify a person included in the acquired image. The control unit 180 can confirm whether or not the contacts for the identified persons are stored in the memory 170. [ The control unit 180 may transmit the folder 30 in which the image and the music file are stored in association with each other to the electronic devices 200_1, 200_2, and 200_3 of the contact, as shown in FIG.

However, the present invention is not limited thereto. The control unit 180 may identify the electronic device within a certain radius when the image is acquired. The control unit 180 may request certain information about the identified electronic devices. The control unit 180 can receive information of the electronic devices which are allowed to access. The control unit 180 may transmit the folder 30 after the creation of the folder 30 by using the information of the electronic devices permitted to access.

According to this, contents can be stored or outputted based on the face recognition result of the occupant performed during the output of the contents, thereby providing contents matching the condition of the occupant while driving. In addition, by storing the stored contents in association with the images obtained after driving, the passenger can recall emotion or the like at the time of image acquisition when the obtained image is confirmed again, thereby improving the emotional quality.

16 is a flowchart of a method of outputting contents set to correspond to an estimated age of a passenger according to an embodiment of the present invention. 17 and 18 are diagrams for explaining outputting contents set to correspond to an estimated age of a passenger according to an embodiment of the present invention.

A method of outputting contents set to correspond to an estimated age of a passenger according to an embodiment of the present invention may be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 16, the control unit 180 can perform face recognition of a passenger (S400).

As described above, the occupant's face recognition may be performed when an event stored in the database occurs. For example, the event may be that the power of the display device 100_2 provided behind the headrest of the front seat of the vehicle 300 is turned on, as shown in FIG. The control unit 180 can acquire the image of the passenger using the camera 121_2. Since the face recognition of the occupant using the obtained image has been described above, a detailed description thereof will be omitted.

16, the control unit 180 may estimate the age of the passenger based on weight information of the occupant included in the sensed information and the result of the face recognition (S410).

Referring to FIG. 17, according to an example, a seat 300 of the vehicle 300 may be provided with a weight detection sensor for sensing the weight of the occupant. It is assumed that a child P 2 and an adult P 3 are aboard the rear seat of the vehicle 300. The weight sensor of each seat can detect weight (W1) of child (P2) and weight (W2) of adult (P3). The sensed weight information may be transmitted to the display device 100_2 as sensing information.

The control unit 180 may estimate the age of the occupant based on the weight information and the result of the face recognition. According to one example, the memory 170 may store information about the average weight of a person according to sex and age. In addition, the average information of the human face according to the age, such as the distance between the eyes, can be stored in the memory 170. The control unit 180 may estimate the age of the occupant by comparing the weight information and the result of the face recognition with the information stored in the memory 170. [

Referring again to FIG. 16, the controller 180 may output the content set to correspond to the estimated age (S420).

Referring to FIG. 18, the controller 180 may display a screen 40 on the display 151_2 of the display device 100_2 to select the content corresponding to the estimated age. Alternatively, the control unit 180 can directly display the content corresponding to the estimated age.

According to this, by outputting the contents set to correspond to the age of the passenger, it is possible to conveniently provide content suitable for the age to the passenger.

FIG. 19 is a flowchart of a method for an occupant to share information about a specific position when the passenger gets off the bus at a specific position and then rides the bus in accordance with an embodiment of the present invention. FIGS. 20 and 21 are diagrams for explaining that a passenger according to an embodiment of the present invention shares information about a specific position based on a result of face recognition of a passenger at the time of getting off and re-driving at a specific position.

The method for the occupant to share information about a specific position at the time of getting off the car at a specific position according to an embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 19, the control unit 180 receives the sensing information obtained from the vehicle from the communication unit of the vehicle [S500], and determines whether or not the occupant has gotten back to the specific position and then boarded again [S510].

Referring to FIG. 20, the controller 180 may perform a navigation operation while driving. The control unit 180 may display the execution screen 50 of the navigation application on the touch screen 151. [ The control unit 180 may display the information 51 about the specific position on the screen 50 during driving.

It is assumed that a passenger gets off at a specific location such as a restaurant or a gas station and then rides again. The control unit 180 can receive the information that the vehicle 300 has stopped from the vehicle 300 and the getting off and re-boarding information of the occupant. The control unit 180 may determine that an event to perform the facial recognition of the occupant has occurred when the occupant is aboard the specific location and then rides again. The determination as to whether or not an event has occurred is substantially the same as that described above, so a detailed description thereof will be omitted.

Referring again to FIG. 19, when the control unit 180 determines that the event has occurred, it can perform face recognition of the occupant (S520).

Based on the result of the face recognition, the control unit 180 can identify the occupant and judge whether the same person has been re-boarded. Further, the control unit 180 can recognize the expression of the passenger based on the result of the face recognition. Since it has been described above with respect to the identification of the passenger and the recognition of the facial expression, a detailed description thereof will be omitted.

Referring again to FIG. 19, the controller 180 may share the information about the specific position with the external device based on the expression of the occupant (S530).

According to an example, the satisfaction value according to the emotion state of the occupant may be stored in advance in the database. For example, various satisfaction values may be set in advance corresponding to the degrees of the contours of the eyes of the passenger or the contours of the mouth.

The control unit 180 can read the corresponding satisfaction value from the database based on the recognized facial expression of the passenger. The control unit 180 may evaluate the read satisfaction value as satisfaction with the specific position. As shown in FIG. 21, the control unit 180 may display an alert 52 indicating the evaluated satisfaction value on the screen 50.

According to an example, the controller 180 may share the satisfaction information of the occupant with respect to the specific location with another person. The contact information of the person who will share the satisfaction information can be set in advance. Alternatively, the control unit 180 may execute the SNS application and upload the satisfaction information together with the information on the specific location to the passenger's SNS.

According to this, the information on the specific location can be conveniently shared by sharing the information on the specific location based on the result of the face recognition of the occupant when the passenger gets off the specific location and then rides again.

22 is a flowchart of a method for outputting contents for preventing sleepiness of an occupant according to an embodiment of the present invention. 23 and 24 are diagrams for explaining outputting of contents for preventing sleepiness of a passenger according to an embodiment of the present invention.

A method of outputting contents for preventing sleepiness of a passenger according to an embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 22, the controller 180 performs face recognition of the occupant (S600), and determines whether the occupant is in the drowsy driving state based on the face recognition result (S610).

According to one example, in connection with preventing drowsiness, an event may occur that will perform the occupant's face recognition. For example, the event may be a case in which the running direction of the vehicle 300 is abnormally determined based on the running information received from the vehicle 300. [ Alternatively, a case where the drowsiness warning signal is received from the control unit of the vehicle 300 may correspond to the event. Alternatively, the event may be a case where a predetermined time has elapsed when the running of the vehicle 300 is maintained for a certain period of time.

When the event is generated, the control unit 180 can perform face recognition of the passenger. Based on the result of the face recognition, the control unit 180 can determine whether the passenger is in the drowsy driving state. According to one example, the controller 180 can determine whether the state in which both eyes of the passenger are kept is maintained for a predetermined time or longer.

However, the present invention is not limited thereto. In order to determine the drowsy driving state of the occupant, a facial expression image of the occupant when the occupant is sleepy may be stored in the database. The control unit 180 can determine that the driver is in the drowsy driving state when the facial expression of the recognized occupant matches the facial expression image at the time of sleeping on the database.

Referring again to FIG. 22, the control unit 180 may output the content set to prevent drowsiness operation (S620).

The content set to prevent the drowsy operation may include a light or exciting music file, a warning sound, or the like. Alternatively, the content may include transmitting a control signal to the communication portion of the vehicle 300 to output the vibration at the steering wheel.

23, an execution screen of a navigation application is displayed on the first display unit 151 of the mobile terminal 100 while the vehicle 300 is running. Information on a music file being played back in the background and a playback control button are displayed on the second display unit 151a.

 Referring to the second display unit 151a, it can be seen that the music file currently being played is a music of a classical genre. As described above, if it is determined that the occupant is in the drowsy driving state, the control unit 180 may play a light or exciting music file instead of the music file currently being played back. For example, referring to FIG. 24, the controller 180 may reproduce the music of the disco genre instead of the music of the classical genre, and may display the music of the disco genre on the second display unit 151a.

According to this, when the occupant is determined to be in the drowsy driving state, the content for preventing drowsiness is output, thereby preventing the driver from drowsy.

25 is a flowchart of a method of notifying an abnormal state based on a result of face recognition of a passenger according to an embodiment of the present invention. 26 to 27 are diagrams for explaining the notification of an abnormal state based on a result of face recognition of a passenger according to an embodiment of the present invention.

The method of informing the abnormal state based on the result of the face recognition by the occupant according to the embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 25, the controller 180 performs the face recognition of the occupant (S700), and determines whether the face of the occupant is in a predetermined abnormal state based on the face recognition result (S710).

According to one example, in connection with the anomaly of the occupant, an event may occur that will perform the occupant's face recognition. The abnormal condition of the occupant may be a state such as a sudden collision of the vehicle 300 or a sudden accident such as sudden braking due to the appearance of a front obstacle or a pain.

The event may be a case where it is determined that the running of the vehicle 300 is abnormally terminated based on the running information received from the vehicle 300. [ Alternatively, a case in which a warning signal related to an abnormal state of the vehicle, such as a collision of the vehicle 300, is received from the control unit of the vehicle 300 may correspond to the event. Alternatively, the event may be a case where an impact of a predetermined value or more is detected by the sensing unit 140.

When the event is generated, the control unit 180 can perform face recognition of the passenger. Based on the result of the face recognition, the control unit 180 can determine whether the occupant is in an abnormal state. According to an example, the database may store a criterion corresponding to an abnormal condition of the occupant. For example, the criteria may be an embarrassed facial image of the occupant or a painful facial image. Or, the outline of both eyes or mouth corresponding to the abnormal condition of the occupant, or the like can be stored as the reference.

The control unit 180 may determine that the occupant is in an abnormal state when the recognized facial expression of the occupant meets the criterion corresponding to the abnormal state on the database.

Referring to FIG. 25, if it is determined that the facial expression of the occupant is abnormal, the control unit 180 may acquire a peripheral image of the vehicle 300 (S720).

Referring to FIG. 26, the mobile terminal 100 may display an execution screen 60 of the navigation application on the touch screen 151 while the vehicle 300 is running. The control unit 180 may drive the camera 121a located on the rear side of the mobile terminal 100 instead of the camera 121 located on the front side of the mobile terminal 100. [

Referring to FIG. 27, the controller 180 may display an image 61 on the front of the vehicle 300, which is obtained by the camera 121a located on the rear side, on the touch screen 151. FIG. According to an example, the control unit 180 may store the forward image 61 in the memory 170. The forward image 61 may be stored as a moving image.

Referring again to FIG. 25, the controller 180 may transmit a signal indicating an abnormal state of the occupant to an external server based on the result of the face recognition.

The external server may be set in advance in relation to an abnormal condition of the occupant. For example, the external server may be preset in a server of a hospital, a server of a police agency, or a server of an insurance company. However, the present invention is not limited to this, and the external server may include any external server as long as it is related to the abnormal state of the occupant.

The control unit 180 can estimate the state of the vehicle 300 based on the information received from the vehicle 300. [ Based on the estimated state of the vehicle 300 and the abnormal state of the occupant, the control unit 180 can select an external server to which the signal informing the abnormal state of the occupant is to be transmitted. The control unit 180 may transmit a signal informing the abnormal condition of the occupant to the external server selected together with the identification information of the passenger or the position information of the vehicle 300. [

According to an example, the controller 180 may display a notification on the touch screen 151 to confirm whether or not the signal is transmitted before transmitting the signal indicating the abnormal state. If an input for selecting rejection of transmission is not received for a predetermined time, the control unit 180 may transmit the signal to the external server.

According to this, it is possible to quickly respond to the abnormal condition of the occupant by notifying the abnormal condition determined based on the face recognition result of the occupant to the outside.

28 is a flowchart of a method of adjusting an indoor condition of a vehicle based on a result of face recognition of a passenger according to an embodiment of the present invention.

The method for adjusting the indoor status of the vehicle based on the face recognition result of the passenger according to the embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 28, the control unit 180 performs face recognition of the passenger [S800], and can determine the indoor state of the vehicle based on the face recognition result (S810).

The control unit 180 may perform face recognition of the occupant when an event to perform face recognition of the occupant occurs. Since it has been described above with respect to face recognition, a detailed description will be omitted.

The control unit 180 can acquire information on the vehicle interior state based on the recognized face image of the passenger. For example, when it is recognized that sweat is formed on the face image of the passenger, the control unit 180 can determine that the room temperature of the vehicle 300 is high. Alternatively, when the grimace of the passenger is recognized during reproduction of the music file, it can be determined that the volume for reproducing the music file is high.

28, the control unit 180 may transmit a control signal for adjusting the indoor state of the vehicle 300 to the communication unit of the vehicle 300 (S820).

For example, when it is determined that the room temperature of the vehicle 300 is high, a control signal for lowering the room temperature of the vehicle 300 may be transmitted to the communication unit of the vehicle 300. The control unit of the vehicle 300 receiving the control signal may control the temperature control system to lower the room temperature of the vehicle 300.

Similarly, when it is determined that the volume of the music file being reproduced is high, a control signal for lowering the volume of the music file can be transmitted to the communication section of the vehicle 300. [ The control unit of the vehicle 300 receiving the control signal may control the audio reproduction device to lower the volume of the music file being reproduced.

According to this, by adjusting the indoor condition of the vehicle based on the face recognition result of the occupant, the indoor condition can be adjusted appropriately for the occupant.

29 is a flowchart of a method of outputting contents received from an external device based on a result of face recognition of a passenger according to an embodiment of the present invention. FIGS. 30 to 31 are diagrams for explaining output of contents received from an external device based on a result of face recognition of a passenger according to an embodiment of the present invention.

A method of outputting content received from an external device based on a result of face recognition of a passenger according to an embodiment of the present invention can be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 29, the controller 180 may receive content related to the passenger from an external device (S900).

According to an example, the external device may be an electronic device that stores or reproduces contents. For example, the external device may be a smart TV 500 provided at the passenger's seat P4, as shown in FIG. The control unit of the smart TV 500 can acquire the image of the passenger P4 using the camera 521 and identify the passenger P4.

The control unit 180 can communicate with the communication unit of the smart TV and receive information about the content 510 viewed by the passenger P4 together with the identification information of the passenger P4. The information on the content may include the content itself or the information for acquiring the content and the playback time information of the content viewed by the passenger P4. The identification information of the passenger P4 may include image or identification information of the passenger P4.

29, the controller 180 performs face recognition of the passenger (S910), and identifies the passenger based on the face recognition result (S920).

31, when the passenger P4 is seated in the back seat of the vehicle 300, the control unit 180 can acquire the face image of the passenger P4 through the camera 100_2. The identification of the occupant's face and the identification of the passenger using the acquired image have been described above, and thus a detailed description thereof will be omitted.

Referring again to FIG. 29, the controller 180 may output the content received from the external device based on the result of the face recognition (S930).

The control unit 180 can check whether there is content corresponding to the identified passenger P4 in the contents received from the external device. If there is content corresponding to the passenger P4, the control unit 180 may display the content 70 on the display unit 151_2. According to an example, the controller 180 can reproduce the content 70 from the time of receiving the content based on the reproduction time information of the content.

According to this, the content received from the external device can be provided to the vehicle occupant by receiving the content received from the external device based on the face recognition result of the occupant.

FIG. 32 is a flowchart of a method for performing an action set to correspond to an event again based on a result of face recognition of a passenger according to an embodiment of the present invention. FIG. 33 is a diagram for explaining an operation that is set to correspond to an event again based on a result of face recognition of a passenger according to an embodiment of the present invention. FIG.

A method of performing an operation set to correspond to an event on the basis of a result of face recognition of a passenger according to an embodiment of the present invention may be implemented in the mobile terminal 100 described with reference to FIG. Hereinafter, a method of controlling a mobile terminal according to an exemplary embodiment of the present invention and an operation of the mobile terminal 100 for implementing the method will be described in detail with reference to the accompanying drawings.

Referring to FIG. 32, the controller 180 may perform facial recognition of a passenger while performing an operation set to correspond to an event (S1000).

According to an example, performing an action set to correspond to an event to perform face recognition of the occupant may be set to correspond to another event to perform face recognition of the occupant. For example, it is assumed that an event to perform face recognition of a passenger occurs, and an operation performed based on a result of face recognition is a route search in navigation.

The control unit 180 searches the route and displays the route on the touch screen 151, and then obtains the occupant's face image through the camera 121. [ The control unit 180 may analyze the obtained face image of the passenger and perform recognition of the passenger and face recognition. The identification of the passenger and the recognition of the facial expression have been described above, and a detailed description thereof will be omitted.

In addition, the control unit 180 may determine whether the occupant confirms the result of the provided route search in the obtained image. According to an example, the controller 180 may determine whether the passenger's gaze is pointing toward the touch screen 151. The present invention is not limited to the specific technique as long as it is a technique for determining whether a line of sight of a person in the image is directed to the touch screen 151.

Referring again to FIG. 32, the controller 180 may determine whether the recognized facial expression of the passenger is negative (S1010).

According to an example, the database may store a criterion for determining whether the expression of the occupant is negative. For example, the criteria may include a froward facial image of the occupant, a licking image of the lips, and the like. Alternatively, the criteria may include a form for both the eyes of the occupant and the outline of the mouth. However, the present invention is not limited thereto. If the expression of the passenger is negative, it can be included in the criterion regardless of the type or form.

According to an example, the controller 180 may determine whether the expression of the occupant is negative when it is determined that the line of sight of the occupant confirms the touch screen 151. The control unit 180 may determine that the facial expression of the passenger is negative when the facial expression of the recognized occupant matches the criterion for determining whether the facial expression of the occupant on the database is negative.

Referring again to FIG. 32, the controller 180 may perform the operation set to correspond to the event again according to another criterion (S1020).

If the expression of the passenger is negative, the control unit 180 can perform the already performed operation again. For example, in the above example, it is assumed that the path search is performed based on the shortest time. In this case, the control unit 180 may perform the path search again based on the shortest path.

According to this, the operation performed according to the generated event is corrected based on the result of face recognition of the passenger, so that the passenger can conveniently provide desired information.

34 is a view for explaining acquisition and storage of images of other passengers according to an embodiment of the present invention.

Referring to FIG. 34, the control unit of the display device 100_2 can acquire the image of the passenger P5 on the rear seat of the vehicle 300 via the camera 121_2. The control unit of the display device 100_2 can recognize the expression of the passenger P5 by analyzing the image of the passenger P5.

The control unit of the display device 100_2 can determine whether the expression of the passenger P5 changes. According to an example, the control unit of the display device 100_2 may be set to continue performing face recognition of the occupant P5. Alternatively, according to another example, the face recognition of the passenger P5 may be set to be performed at a predetermined time interval.

The control unit of the display device 100_2 can store the image of the occupant P5 when the expression of the occupant P5 is different from the expression of the occupant P5 in the image stored immediately before. The control unit of the display device 100_2 may transmit the stored image to the mobile terminal 100 mounted in front of the vehicle as shown in FIG.

The control unit 180 of the mobile terminal 100 may store the image of the received occupant P5 in the memory 170. [ The control unit 180 may display the notification 90 that the image of the passenger P5 has been stored on the touch screen 151. [

According to this, an image of a passenger on another seat can be acquired and stored and displayed in accordance with a change in expression, so that an image in which the expression of a passenger on another seat can be changed can be easily confirmed.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded.
