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 senses 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, do.

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.

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.

Therefore, the driver can easily grasp the information that he / she is interested in, without moving his or her eyes to check the information about the specific point during driving.

Hereinafter, embodiments related to a control method that can be implemented in a vehicle display apparatus configured as above will be described in more detail with reference to the accompanying drawings.

In other words, it is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

FIG. 3A is a flowchart of a method of controlling a display device for a vehicle according to an embodiment of the present invention, and FIGS. 3B and 3C are views for explaining a method of controlling a display device for a vehicle according to an embodiment of the present invention.

3A, a vehicle display apparatus according to an exemplary embodiment of the present invention can detect a driver's gaze (S301).

The driver's gaze can be sensed through the camera included in the vehicle display device 200. [ For this purpose, the vehicle display device 200 may include a line-of-sight camera capable of tracking the driver's gaze. In addition, the vehicle display apparatus 200 can receive the driver's gaze information sensed by a camera provided in a separate electronic apparatus (for example, the mobile terminal 100) through wireless communication with the electronic apparatus have.

Further, the vehicle display apparatus may receive position information of the vehicle on which the driver is boarding (S302).

The wireless communication unit 206 of the vehicle display device can receive the location information of the vehicle from an external server. In addition, when there is an external electronic device capable of wireless communication with the vehicle display device in the vehicle, the vehicle display device can receive the positional information according to the movement of the vehicle from the external electronic device.

The location information of the vehicle may be continuously received through the external server regardless of whether the driver's gaze is sensed, whether the driver's gaze is sensed, or whether the driver's gaze is sensed.

When the driver's sight line information and the vehicle position information are obtained, the controller 212 of the vehicle display device can calculate the line-of-sight distance of the driver using the sight line of the driver and the vehicle position information (S303) .

The controller 212 can analyze the driver's gaze sensed through the camera. For example, the control unit 212 may analyze the driver's gaze based on the movement of the driver's eyeball, the direction of the eyeball, and the motion of the driver's head photographed through the camera.

Also, the controller 212 can calculate the line-of-sight reaching distance from the position of the vehicle to the point at which the driver's line of sight is reached, using the position information of the vehicle. The controller 212 may use the angle formed by the line of sight corresponding to each of the left and right eyes of the driver in calculating the line-of-sight reaching distance. That is, the controller 212 measures the angle using the difference of the line-of-sight reaching distance as the angle formed by the line of sight corresponding to each of the left and right eyes of the driver changes, Can be determined as the line-of-sight reaching distance,

For example, when the angle formed by the line of sight corresponding to each of the left and right eyes of the driver is measured by the first angle, a first distance that is a distance corresponding to the first angle may be calculated as the line-of-sight reaching distance. Alternatively, when the angle formed by the line of sight corresponding to each of the left and right eyes of the driver is measured as a second angle having a value smaller than the first angle, a second distance corresponding to the second angle is measured as the line- / RTI > In this case, the second distance may have a value larger than the first distance.

3B, the driver can look at a certain point A 10 in the forward direction through the windshield area 401 of the vehicle 400, and the camera 227, The driver's eyes can be detected. In addition, the controller 212 analyzes the driver's gaze sensed by the camera 227 and calculates an angle value a formed by the gaze corresponding to each of the left and right eyes of the driver.

3C, when the driver looks at another point B 20 on the front side of the vehicle 400, the control unit 212 detects the position of the vehicle 400 detected by the camera 227 The angle value b formed by the line of sight corresponding to each of the binaural directions of the driver can be calculated.

At this time, when looking at a certain point A 10 located relatively far from the front of the vehicle 400, the angle value a formed by the line of sight corresponding to each of the two eyes of the driver is relatively different from the other point B (B) of the line of sight corresponding to each of the eyes of the driver when the user looks at the camera 20, as shown in FIG.

 Accordingly, the controller 212 can calculate the line-of-sight reaching distance using the angle formed by the line of sight corresponding to each of the eyes of the driver. Also, the control unit 212 may use the data stored in the memory 213 to calculate the line-of-sight reaching distance.

The data may be data relating to an angle formed by a line of sight corresponding to each of the left and right eyes of the driver and a line-of-sight reaching distance corresponding to the angle. In addition, the data may be stored in the memory 213, or may be data continuously acquired or accumulated through a user's visual analysis. Also, the data may be data received for the eye analysis on an external server.

When the line-of-sight reaching distance is calculated as described above, the control unit 212 can determine a point of sight of the driver (S304).

The control unit 212 may use predetermined map data to determine a point of sight of the driver. The predetermined map data may be map data for an area within a predetermined range from a point corresponding to the position information of the vehicle. The map data may be received from an external server by the wireless communication unit 206 together with the location information of the vehicle, or may be map data stored in the memory 213 in advance.

The control unit 212 may extract a plurality of points located at a distance corresponding to the line-of-sight reaching distance from the point corresponding to the vehicle position information in the map data. A point of the driver's gaze can be determined using the direction of the driver's gaze among the plurality of points. In this case, the controller 212 may determine a direction in which the driver's line of sight is maintained for a predetermined time or more in a direction in which the driver's line of sight is directed.

For example, as shown in the second diagram of FIG. 3B, the control unit 212 may display the map data 30 for the area including the position of the vehicle 400, A plurality of points can be extracted using the reach distance la. Also, the driver can determine a point A 10 of the plurality of points at which the driver's line of sight is directed, using the direction of the driver's gaze obtained through the camera 227.

Similarly, as shown in the second diagram of FIG. 3C, the controller 212 calculates a line-of-sight reaching distance lb corresponding to the angle value b, , It is possible to determine the point B (20).

Although not shown in the drawing, when the driver's line of sight is maintained in the first direction for a predetermined time or longer and then maintained in the second direction for a predetermined time or longer, the controller 212 controls the position corresponding to the first direction It is possible to determine each of the points corresponding to the two directions as the point at which the line of sight of the driver faces.

When the driver's line of sight is determined as described above, the controller 212 may output the information related to the determined point to the display unit 201 (S305).

The information related to the determined point may be at least one of advertisement information about the determined point, position information of the determined point, information about a place associated with the determined point, and event information associated with the determined point.

For example, as shown in FIG. 3B, when the determined location is a shopping mall, information related to the determined location may include event information (discount information or lottery information, etc.) associated with the shopping mall, advertisement information of the shopping mall, and the like. As another example, if the determined point is a restaurant, the information related to the determined point may be event information (recommendation menu information) associated with the restaurant, information about a place (parking lot, convenience facility) associated with the restaurant, And detailed location information of the restaurant (building name or specific address, etc.).

The information related to the determined point may be information stored in the memory 213 in advance. In this case, the information related to the determined point may be updated at a predetermined period. The control unit 212 may control the wireless communication unit 206 to transmit a signal requesting reception of information related to the determined point to an external server when a point of sight of the driver is determined.

In addition, the controller 212 may output the information related to the determined point to the display unit 201. If there are a plurality of pieces of information related to the determined point, the control unit 212 can select information to be output to the display unit 201 among the plurality of pieces of information based on predetermined conditions. An embodiment related to this will be described later with reference to Figs. 4A and 4B.

In addition, the control unit 212 may control the display unit 201 so that the output method of information related to the determined point output to the display unit 201 is changed according to a specific condition. This will be described later with reference to Figs. 5A and 5B.

When the information related to the determined point is output to the display unit 201, the control unit 212 can control the display unit 201 so that information related to the determined point is projected onto the windshield area of the vehicle. More specifically, the control unit 212 may control the display unit 201 so that information related to the determined point is projected to a position corresponding to the driver's line of sight of the windshield area.

3B and 3C, the information 10a related to the shopping mall and the information 20a related to the restaurant are associated with the position of the windshield 401 facing the driver's line of sight Can be output to one area.

Therefore, the driver can easily receive various information related to the specific point by a simple operation such as keeping a gaze at a specific point of interest. In addition, since the information related to the specific point is projected at a position facing the driver's line of sight of the windshield area, the driver can clearly and easily confirm the desired information while performing the operation, There is an effect of reducing the accident risk of the vehicle.

On the other hand, the information related to the determined point may include various kinds of information as described above. In this case, the control unit 212 can select information to be output to the display unit 201 from among the plurality of pieces of information based on predetermined conditions.

The predetermined condition may be a condition set by the driver (for example, a condition for limiting the output of the advertisement information or a condition for outputting only the detailed position information). In addition, the preset condition may be status information such as the time, the date, and the location of the vehicle, where the driver's gaze was sensed. In this case, the control unit 212 may output the information related to the preset condition among the plurality of pieces of information to the display unit 201.

Hereinafter, this will be described with reference to Figs. 4A and 4B.

FIGS. 4A and 4B are views showing an embodiment in which information output to the display unit is changed according to predetermined conditions.

Referring to FIG. 4A, when the B restaurant 20 is determined as a point of sight of the driver, the controller 212 may collect information related to the B restaurant 20. Information related to the B restaurant 20 may be stored in the memory 213 or received from the external server through the wireless communication unit 206. [

If the type of information related to the B restaurant is determined by the driver under the predetermined condition, the controller 212 selects information corresponding to the condition among the information related to the B restaurant stored in the memory 213 . Also, the control unit 212 may control the wireless communication unit 206 to receive only information corresponding to the condition.

Accordingly, as shown in FIG. 4A, information (parking lot, convenience information) related to a place associated with the B restaurant selected by the above conditions may be output to the display unit 201. [ Further, when the condition is the specific information (for example, the time to wait for the use of the B restaurant or the information on the current waiting person) for the use of the B restaurant at the time when the driver's gaze is sensed, Information may be output to the display unit 201. [ In this case, the controller 212 may control the wireless communication unit 206 such that specific information related to the B restaurant is received from an external server at the time the driver's gaze is sensed.

4A, the controller 212 controls the display unit 201 so that the information output from the display unit 201 is projected to a position 20b corresponding to the driver's line of sight in the area of the windshield 401 Can be controlled.

Alternatively, the information output to the display unit 201 may be determined based on status information related to the time when the driver's gaze is sensed. The state information related to the point of time when the driver's gaze is detected may include various state information such as the time, date, weather corresponding to the driver's gaze, weather, vehicle speed, and the like.

For example, referring to FIG. 4B, when the controller 212 determines that the A shopping mall 10 is located at a point where the driver's line of sight is directed, the controller 212 outputs the information related to the A shopping mall 10 to the display unit 201 Information can be selected based on the status information. That is, when the state information of the time and date when the driver's gaze is sensed is registered with the predetermined condition, the information related to the time and date among the information related to the A shopping mall can be output to the display unit 201 .

For example, when the driver's line of sight is sensed at a specific date or at a specific time of a discount event occurring in the shopping mall, the controller 212 determines whether the information related to the specific shopping mall Information on the display unit 201 can be output. More specifically, the discount information corresponding to the period including the specific date and the event information corresponding to the time range including the specific time may be output to the display unit 201.

The information output to the display unit 201 may be projected to a position 10b corresponding to the driver's line of sight of the windshield 401. [

Accordingly, the driver can distinguish the desired information or the unwanted information through the setting. In addition, the information related to the determined point is selectively output according to the current state information, so that it is possible to provide the driver with the most appropriate information in the current state.

The information output to the display unit 201 may be output in different ways depending on the type of information. For example, the event information associated with the determined point and the detailed position information of the determined point may be output to have different sizes, colors, and fonts.

Also, the information output to the display unit 201 can be changed based on the state information of the vehicle being changed. The state information of the vehicle may be information on the state of the vehicle such as whether the vehicle is running, the speed of the vehicle, the direction of the vehicle, and the position of the vehicle. For example, the previously output information may be enlarged and output based on the vehicle moving at a speed that is higher than the vehicle speed at which the determined point and the vehicle are close to each other or information related to the determined point is output.

Hereinafter, an embodiment related to this will be described with reference to Figs. 5A and 5B.

Figures 5A and 5B are diagrams illustrating embodiments related to various output schemes of information associated with determined points.

Referring to FIG. 5A, the controller 212 may output event information, location information, and the like of the B restaurant to the display unit 201 as information related to the determined point (B restaurant). In this case, the control unit 212 may control the display unit 201 so that the respective information related to the B restaurant (today's recommended menu information, pricing information, location information) are output in different manners.

For example, the control unit 212 may output today's recommended menu information among the information related to the B restaurant on the display unit 201 relatively larger than other information (price information, location information). Also, the control unit 212 may control the display unit 201 to output the price information and the position information in different fonts.

In this case, the control unit 212 can control the display unit 201 so that the information output to the display unit 201 is projected onto the area of the windshield 401 according to an output method corresponding to each of the information have. 5A, in the area of the windshield 401, the area 21a in which the recommendation menu information of today is projected is different from the area 21b or 21c in which the other information (price information, position information) It can have a large size. In addition, the price information and the location information may be projected in one area of the windshield 401 in a font different from each other.

Accordingly, even when a plurality of pieces of information related to the determined point are output at once, each of the plurality of pieces of information is output in a different manner, so that the driver can quickly and easily confirm desired information among other information items.

On the other hand, the controller 212 may output the information related to the determined point to the display unit 201, and then change the output method based on a specific condition (for example, vehicle status information).

5B, information (today's recommendation menu, price information and location information) related to the determined point (B restaurant 20) is output to the display unit 201, and the vehicle 400 The information can be projected onto one area 20c on the windshield 401 of the vehicle.

In addition, the controller 212 may collect status information of the vehicle 400. That is, the controller 212 can determine the current state of the vehicle 400 using the position information and the speed information of the vehicle 400.

For example, the control unit 212 may use the speed sensor included in the vehicle display device 200 or the position information of the vehicle received through the wireless communication unit 206, The speed of the vehicle can be calculated. The location information of the vehicle 400 received from the wireless communication unit 206 can be used to determine the relative position between the determined point (B restaurant 20) and the vehicle 400.

When the state information of the vehicle 400 is obtained, the controller 212 can change the output method of the information output in relation to the determined point (B restaurant 20) based on the state information. That is, if it is detected that the position of the vehicle 400 is approaching the determined point (B restaurant 20) as shown in the second drawing of FIG. 5B, the control unit 212 controls the display unit 201, The information related to the branch (restaurant B, 20) can be enlarged and output.

Further, the magnified and outputted information can be projected to the area of the windshield 401 of the vehicle 400. In this case, when the position of the driver's line of sight in the area of the windshield 401 is changed in accordance with the movement of the vehicle 400, the control unit 212 controls the magnification so that the enlarged information is projected to the changed position 21. [ The display unit 201 can be controlled.

Although not shown in the drawing, the control unit 212 may adjust the output size of the information related to the determined point, or may change the output color or the font so that a part of the information blinks, Can be changed.

In addition, although not shown in the drawing, if there are a plurality of points determined based on the sight line of the driver, the controller 212 can output information on each of the plurality of points to the display unit 201 at one time have. In this case, the control unit 212 may enlarge or output a part of the plurality of pieces of information based on the state information of the vehicle (a movement direction of the vehicle or a positional change relative to the determined position), or may output the pieces of information.

Accordingly, as the driver approaches the point of interest, the driver can reliably grasp information related to the point of interest.

In addition, the control unit 212 may change the output mode of the information related to the determined point based on the change of the speed or the moving direction of the vehicle, in addition to the determined position and the relative position of the vehicle. For example, as the moving direction of the vehicle changes, information related to the determined point may be reduced and output.

The vehicle display apparatus 200 can change the output state of the information based on the detection of the driver's gesture in a state in which the information related to the determined point is outputted. That is, the vehicle display apparatus 200 senses a motion gesture of the driver's hand, a blinking gesture, etc. through the sensing unit 230, changes the previously output information to correspond to the detected gesture, Other information can be added to the information to be output.

In addition, the vehicle display apparatus 200 can change the output state of the information based on an additional control command such as an audio input of the driver. Hereinafter, with reference to FIGS. 6A, 6B, and 6C .

6A, 6B, and 6C are views showing an embodiment in which the output state of information related to a point determined based on an additional input of a driver is changed.

6A, today's discount information is output in relation to the determined point A shopping mall 10 in the display unit 201 and the control unit 212 controls the windshield 401 of the vehicle 400 It is possible to control the display unit 201 so that the discount information of the present day is projected in one area 10c.

The vehicle display device 200 includes a sensing unit 230 for sensing a gesture of a driver and is driven by an optical sensor (camera) 227 included in the sensing unit 230 so that the driver's eye blinking gesture Can be detected. For example, the blinking gesture may include a blinking of at least one of a left eye and a right eye, a predetermined number of eye blinks, and the like.

6A, when the driver's preset blinking gesture of the eyes is sensed, the controller 212 may change information (today's discount information) related to the determined point to other information and output the information have.

For example, if the information related to the determined point is event information related to the determined point, based on the detection of the flicker of the predetermined eye, the event information may include detailed information including the specific content of the event information Can be changed and output.

The control unit 212 may control the display unit 201 so that the changed information is projected to the position 10d corresponding to the driver's line of sight in the area of the windshield 401. [

On the other hand, in the first drawing of FIG. 6B, the position information related to the determined point is outputted and other information may be added to the position information based on the detection of the hand movement gesture of the driver.

That is, when the movement gesture of the hand of the predetermined driver is sensed from the sensing unit 230, the controller 212 determines whether the position of the predetermined position is a position (a place of a business type similar to a parking lot or the determined point) Can be additionally output. Here, the movement of the predetermined driver's hand may be defined as a movement gesture of a variety of hands, such as moving the hand in a specific direction, clapping, or holding a fist.

The control unit 212 may control the display unit 201 so that the further output information is projected to a position 22b corresponding to the driver's line of sight in the windshield 401 area. Although not shown in the figure, the controller 212 may control the display unit 201 so that the previously output information (location information) and the additional output information (parking lot or other point information) are separately outputted.

In addition, the driver can input a control command related to the output of desired information by voice so that the driver can output desired information. That is, referring to FIG. 6C, in a state in which information related to a determined point is output, the driver can designate desired information (route guidance to the determined point) by voice and input the information.

In this case, the controller 212 analyzes the voice inputted by the driver and can search information corresponding to the voice. That is, the controller 212 searches the memory 213 for information stored in association with the determined point, or searches the external server for information corresponding to the voice through the wireless communication unit 206.

In addition, the display unit 201 can be controlled so that information corresponding to the voice is projected to a position 23b corresponding to the driver's line of sight of the windshield 401. [

Accordingly, the driver is provided with the convenience of additionally confirming other information related to the determined point or more specific information through a simple gesture even after receiving the information related to the point of interest of the driver.

In this manner, after the information related to the determined point is output, the driver may not want to receive further information related to the determined point. In this regard, the control unit 212 may terminate the output of the information if a specific condition is satisfied.

For example, the control unit 212 may terminate the output of the information based on the elapse of a predetermined time after the information is output. Also, the controller 212 may terminate the output of the information if the position of the vehicle is sensed to be out of the area corresponding to the determined point. Hereinafter, embodiments related to this will be described with reference to FIGS. 7A and 7B.

Figures 7A and 7B show an embodiment relating to the output termination of information associated with a determined point.

Referring to FIG. 7A, the controller 212 controls the display unit 201 so that information related to the determined point is projected to a position 11 corresponding to the driver's line of sight of the windshield 401 have. After the information is output, the control unit 212 may determine whether a predetermined time has elapsed using the sensing unit 230. [

If it is detected that the predetermined time has elapsed since the information related to the determined point is output, the controller 212 may terminate the output of the information related to the determined point. Therefore, as in the second diagram of FIG. 7A, the information related to the determined point may not be projected in the area of the windshield 401.

Alternatively, when the vehicle 400 is out of the area corresponding to the determined point, the control unit 212 may terminate the output of information related to the determined point.

If the condition of the predetermined time and the condition of the determined point and the relative position of the vehicle are satisfied, whether or not the output of the information is completed can be changed. That is, when the control unit 212 detects that the position of the vehicle is out of the area corresponding to the determined point even though the predetermined time has not elapsed since the information related to the determined point is output, The output of the information can be terminated.

However, even if the preset time has elapsed after the information related to the determined point is output as shown in FIG. 7B, the vehicle (FIG. 7B) is displayed in the area 31a corresponding to the determined point 10, 400 may not be released. In this case, it may be in accordance with the intention of the user to continuously provide information related to the determined point.

Therefore, the control unit 212 can control the display unit 201 so that information related to the determined point is continuously projected onto one area 11 of the windshield 401, as shown in the third diagram in FIG. 7A have.

After the information related to the determined point is output, control is performed so as to match the intention of the user by determining whether or not the output is ended based on a specific condition (degree of change in time or vehicle position) .

Meanwhile, the vehicle display apparatus 200 can perform wireless communication with an external device (e.g., a mobile terminal), and can transmit and receive information through the wireless communication. Further, the external device can be controlled by transmitting a control signal to the external device. For example, after outputting information related to the determined point, information related to the determined point may be transmitted to the external apparatus. In addition, the external device may transmit the control command to the external device to perform a specific function using the information related to the determined point.

In this regard, description will be made with reference to Figs. 8A and 8B.

8A and 8B are views showing an embodiment of performing wireless communication with an external device using information related to a determined point.

Referring to FIG. 8A, when event information is projected in one area 12 of the windshield 401 in relation to the determined point, the driver can input a predetermined operation gesture.

As shown in the second diagram of FIG. 8A, when the operation gesture of the driver is sensed, the controller 212 can perform a specific function corresponding to the operation gesture. For example, the specific function may be a function of transmitting event information related to the determined point to an external device (for example, the mobile terminal 100).

Here, the external device 100 may be an external device capable of performing wireless communication with the vehicle display device 200 in close proximity, and may be previously set to be associated with the vehicle display device 200.

In this case, the controller 212 controls the wireless communication unit 206 to transmit the event information to the external device 100 based on the detection of the user's operation gesture as shown in the third diagram of FIG. 8A . The event information may be transmitted to the external device in the form of text information on the content of the information or may be transmitted to the external device 100 in the form of captured image information in a state where the event information is output to the display unit 201 .

Alternatively, the driver can directly input a control command to control the external device 100 using the information related to the determined point.

That is, as shown in FIG. 8B, usage information (standby personnel) and positional information related to the determined point may be projected onto one area 24 of the windshield 401. At this time, as shown in the second drawing of FIG. 8B, the driver can input a function to be performed by voice command using information related to the determined point.

In this case, the controller 212 analyzes the voice command of the driver and transmits a control command to the external device 100 so that a corresponding function is executed. For example, if the function corresponding to the voice command is a call origination function to the determined point, the control unit 212 searches for the telephone number information of the determined point according to the voice command, And send a call origination control command to the external device (100).

Alternatively, the control unit 212 may transmit the determined point information to the external device 100, and may transmit a control command of the telephone connection to the determined point. In this case, the external device 100 can search for the telephone number of the determined point based on the control command, and perform the call origination function.

In this way, the vehicle display apparatus 200 displays information related to a point of interest of the driver, and can be interlocked with an external device based on an additional input (voice input or gesture input) of the driver. Accordingly, the driver is not only provided with information on the point of interest but also is provided with the convenience of performing various functions using information on the point of interest.

The vehicle display apparatus and the control method thereof according to an embodiment of the present invention may determine a point at which the driver's line of sight is directed through the sight line analysis of the driver and then output information related to the determined point. Accordingly, the driver can easily receive desired information without any additional input such as directly searching for information related to his / her point of interest.

Further, since the information related to the determined point is projected at a position facing the driver's line of sight in the windshield area of the vehicle, the driver does not have to move his or her eyes to confirm the information related to the determined point during driving, To provide comfort to the driver.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
