FIG. 4 is a diagram illustrating an input screen displayed on a display, FIG. 5 is a diagram illustrating a Fitts' And FIG. 6 is a diagram for explaining a method of obtaining the line-of-sight vector of the driver.

The display device 200 can provide the driver with various types of screens for receiving information related to the entire vehicle, each configuration of the vehicle, and / or an external device connected to the vehicle, and control commands.

To this end, the display device 200 may be implemented with an audio device 133, a video device 134, a navigation device 135, or an AVN device including it, but is not limited thereto, It may be sufficient to include a display 240 that can process the data received from the above-described apparatus and provide it to the user.

3 shows a display device 200 that is connected to an audio device 133, a video device 134, a navigation device 135, a smartphone 136, an electronic control unit 137 in a vehicle, .

Referring to FIG. 3, a display device 200 according to an embodiment includes a camera 220; An input unit 230; A control unit 210; A storage unit 138; And a display 240; . ≪ / RTI >

The control unit 210 receives information from the ECU 137 that controls the entire vehicle, an audio device 133 installed in the vehicle, a video device 134, and navigation 135, and a smartphone 136 connected to the vehicle from the outside . At this time, the information to be received may include information about the entire vehicle (for example, driving-related information), audio and video information, navigation information, and the like.

The control unit 210 may process the received information so as to provide the information to the driver. For example, when receiving audio or video information, the control unit 210 may process the audio or video information to be reproducible on the display 240, which will be described later.

Alternatively, when various information related to the vehicle is received, the control unit 210 arranges the data received on the predetermined screen form and provides the data to the display 240 so that the driver can visually confirm the data. At this time, the control unit 210 can retrieve the screen form stored in advance from the storage unit 138. [

Also, the control unit 210 may provide various types of input screens related to the control of the vehicle. The input screen may be implemented by a UI (User Interface) or a GUI (Graphic User Interface), and the control unit 210 may invoke the input screen pre-stored from the storage unit 138 or may generate an input screen.

The control unit 210 may be implemented as an integrated circuit in a microprocessor, software such as firmware, or may be implemented as a separate instruction.

The display 240 can display information processed by the control unit 210. [ The driver may be provided with various information related to the vehicle through the screen displayed on the display 240, or may be provided with audio or video images.

For this, the display 240 may be implemented in the form of a panel, and a liquid crystal display (LCD) panel or an organic light emitting diode (OLED) panel may be employed. However, the display 240 is not limited to the above-described embodiment.

Also, the display 240 may display an input screen for receiving input relating to vehicle control from the driver. For example, the display 240 may display a driving control screen, an audio device control screen, a video device control screen, a navigation control screen, and the like.

At this time, the input screen may include a plurality of icons corresponding to the user's control command. A plurality of icons may be classified according to categories, and icons belonging to the same category may be disposed adjacent to each other.

In addition, the display 240 may include a cursor S for indicating any one of a plurality of icons on the input screen. The cursor S may move continuously across the entire area of the display 240 or discontinuously move between a plurality of icons.

In the case of the input screen shown in FIG. 4, the navigation control screen is illustrated, but includes icons belonging to categories that are not related to the navigation control.

Specifically, the input screen of Fig. 4 includes a C1 category group, which is an icon set belonging to the top level category for controlling navigation, an audio device, a telephone, a video device, and vehicle information, a C2 category group in which an icon for receiving a command for a navigation map is placed, Category group, a C3 category group, which is an icon set for navigation control, and a C4 category group, which is an icon set for controlling the air conditioner 131. [

In addition, in FIG. 4, the cursor S is illustrated as moving in a discontinuous manner, and it can be confirmed that it is located on a road icon currently belonging to the category C3.

The driver can visually confirm the displayed input screen and input the control command through the input unit 230. [

The input unit 230 may be provided in a separate configuration or may be provided together with the display 240 when the display 240 is implemented as a touch screen.

Alternatively, the input unit 230 may include an input unit 230 having a different configuration as described with reference to FIG. For example, the input unit 230 may include the dial control unit 122 of FIG. Hereinafter, the case where the input unit 230 is implemented as the dial control unit 122 will be described.

When the input screen of FIG. 4 is displayed on the display 240, the driver can move the cursor S by operating the dial control unit 122 of the input unit 230. FIG.

For example, when the driver rotates the dial control unit 122 of the input unit 230 in the clockwise direction, the cursor S moves to the left, and when the leftmost icon is reached, the rightmost icon of the upper row adjacent to the current row Can be moved. On the contrary, when the driver rotates the dial control unit 122 of the input unit 230 counterclockwise, the cursor S moves to the right, and when the rightmost icon is reached, the leftmost icon of the lower row adjacent to the current row Can be moved.

The display device 200 can be variously embodied in the technical idea that the cursor S moves on the display 240 when the dial control part 122 of the input part 230 rotates have.

When the driver moves the cursor S to reach the area where the desired icon is displayed, the driver can press the dial control unit 122 of the input unit 230 or input a selection command through a separate input button. As a result, the function corresponding to the selected icon can be performed.

At this time, when the cursor S is far away from the icon to be selected, the driver may have a long time to operate the input unit 230 to move the cursor S. In particular, when the cursor S moves discontinuously between a plurality of icons, the cursor S moves sequentially in accordance with a predetermined path, so that it takes a lot of time for the operator to input a control command.

As a result, the driving concentration of the driver may be lowered, which may be a great risk factor for driving.

Accordingly, there is a need to provide a display device 200 that reduces the time for the driver to select any one of a plurality of icons.

On the input screen displayed on the display 240, the average time taken to reach the target point from the initial starting point follows the Fitts' Law. For example, as shown in FIG. 5, when the cursor S located at the current point A reaches the icon B, the required time T follows the equation (1).

Here, T means the average time required, and D means the distance to the center of the icon B. W denotes the width of the icon B when the moving direction is the axis, and a and b denote experimental constants.

According to Fitz's Law, to reduce T, we have to increase W and shorten D,

In other words, when shortening the time required to reach the icon to be selected, the icon to be selected must be enlarged and the cursor S must be adjacent to the icon to be selected.

To this end, the display 240 may enlarge and display the category group to which the icon to be selected belongs, or move the cursor S to a position close to the category group to which the icon to be selected belongs.

At this time, the category group to which the icon that the driver wants to select belongs can be obtained by using the sight line vector of the driver.

Referring to FIG. 3, the camera 220 may capture an eye of a driver. To this end, the camera 220 may be located within an area within the vehicle where the driver ' s eye can be captured. In particular, camera 220 may be installed adjacent to display 240 to obtain a line of sight vector to display 240.

When the eyes of the driver are captured, the control unit 210 can acquire the gaze vector of the driver based on the eyes of the driver.

Referring to FIG. 6, a coordinate axis can be set based on the center of the eyeball. At this time, the coordinates of the pupil center point of the eyeball captured on the set coordinate axis become the position vector of the driver's gaze. That is, the vector of the center of the pupil from the center of the eyeball can be referred to as the driver's gaze vector. In FIG. 6, an arrow passing through the center of the pupil means a line of sight of the driver.

At this time, the control unit 210 can use a signal processing filter. Since the driver's gaze changes very quickly, a meaningless gaze vector can be obtained when all of the eyes captured in real time by the camera 220 are used. Therefore, the control unit 210 can reduce the error of the line-of-sight vector obtained by using the signal processing filter for blocking the meaningless data.

For example, the signal processing filter may remove noise by obtaining an average value of a line-of-sight vector within a predetermined time, but is not limited thereto.

The control unit 210 can confirm the area of the display 240 to which the acquired eye vector is directed. As shown in FIG. 6, when the driver looks at the display 240, the line of sight vector may be directed to one area of the display 240.

If the driver looks at an icon to be selected, the control unit 210 can obtain the driver's gaze vector. At this time, there is a high probability that the category group including the icon to be selected is displayed in the area of the display 240 to which the obtained sight line vector is directed. Accordingly, the control unit 210 displays the category group displayed in the area of the display 240 to which the obtained sight line vector is directed, or controls the display 240 to position the cursor S at a position close to the category group .

Finally, the driver can quickly select a desired icon by moving the cursor S through the input unit 230. [ This will be described with reference to FIGS. 7 and 8. FIG.

FIGS. 7A and 7C are diagrams for explaining an embodiment of a method for the driver to select an icon desired.

As shown in FIG. 7A, the display 240 may display an input screen composed of groups in a plurality of categories including at least one icon. At this time, the driver can look at the icon to be selected.

The camera 220 can capture the driver ' s eyeball in real time. The control unit 210 can obtain the line of sight of the driver based on the eye captured by the camera 220. [ The method of acquiring the line-of-sight vector of the driver is as described with reference to FIG.

Then, the control unit 210 can confirm the area of the display 240 to which the obtained sight line vector is directed. In FIG. 7A, it can be seen that the driver's gaze vector is directed to the area of the display 240 where the telephone icon is displayed.

As a result, as shown in FIG. 7B, the display 240 can enlarge and display the C1 category group including the phone icon. Correspondingly, the display 240 can reduce and display the C2 category group adjacent to the C1 category group. In FIG. 7B, the case where the C3 category group and the C4 category group are not reduced is illustrated. However, the display 240 may display all the remaining category groups except for the category group to which the area directed by the sight line vector belongs.

7C, the driver can move the cursor S to the icon to select the cursor S by operating the dial control unit 122 of the input unit 230. [ 7C, the driver operates the dial operating section 122 to move the cursor S, which was located on the navigation icon, to the telephone icon.

Since the entire C1 category group is enlarged, the time taken to move the cursor S as illustrated in Fig. 7C can be shortened. As a result, since the driver completes the operation of the input unit 230 quickly, it is possible to prevent the driving concentration from being lowered.

7A to 7C illustrate a display 240 that enlarges and displays a category group corresponding to a direction in which a gaze vector is automatically directed when a gaze vector is acquired. However, after the display 240 obtains the line-of-sight vector, it may be possible to expand the category group if an enlargement command is detected from the driver.

Specifically, as shown in FIG. 7A, when the driver's gaze vector is acquired, the display 240 can highlight and display the C1 category group. For example, the display 240 may add a highlight effect to the C1 category group.

The driver visually confirms this and can input an enlargement command if he wants to expand the C1 category group. The magnify command may be input through the input unit 230 or may be obtained by the camera 220 sensing the gesture of the driver's eyeball. For example, if the driver blinks his / her eyes, the camera 220 senses the blinking and transmits the sensed result to the controller 210.

After confirming that the enlargement command has been inputted, the control unit 210 may control the display 240 to enlarge the category C1 as shown in FIG. 7B.

8A to 8C are diagrams for explaining another embodiment of a method for the driver to select a desired icon.

Figure 8A also shows that the display 240 can display an input screen consisting of groups of a plurality of categories including at least one icon, as shown in Figure 7A. In FIG. 8A, the cursor S is located on an icon of interest belonging to the C3 category group.

At this time, the driver can look at the icon to be selected. The camera 220 can capture the eyeball of the driver looking at the display 240 in real time and the control unit 210 can acquire the sight line vector of the driver based on the eyeball captured by the camera 220. [

Then, the control unit 210 can confirm the area of the display 240 to which the obtained sight line vector is directed. In FIG. 8A, it can be seen that the driver's gaze vector is directed to the area of the display 240 where the phone icon is displayed.

As a result, as shown in FIG. 8B, the display 240 can move the cursor S into a group of C1 categories including a phone icon. Specifically, in FIG. 8B, it can be seen that the display 240 has positioned the cursor S, which was located on the interest icon belonging to the C3 category group, on the navigation icon belonging to the C1 category group.

In FIG. 8B, the display 240 has moved the cursor S to the navigation icon, but can move anywhere in the icon belonging to the C1 category group.

 8C, the driver can move to the icon to select the cursor S by operating the dial control unit 122 of the input unit 230. [ In Fig. 8C, the driver operates the dial operating section 122 to move the cursor S, which was located on the navigation icon, to the telephone icon.

Since the cursor S positioned on the icon of interest is moved to the navigation icon and the distance from the icon is shortened, the time taken to move the cursor S as illustrated in FIG. 8C may decrease. As a result, since the driver completes the operation of the input unit 230 quickly, it is possible to prevent the driving concentration from being lowered.

In Figs. 8A to 8C, the case where the cursor S is moved into a category group displayed in an area facing the sight line vector is exemplified. Alternatively, it may be possible that the cursor S is moved from the category group to an area within a predetermined distance.

8A to 8C illustrate a display 240 that enlarges and displays a category group corresponding to a direction in which a gaze vector is automatically directed when a gaze vector is acquired. However, after the display 240 obtains the line-of-sight vector, it may also be possible to move the cursor S into the category group if a cursor S move command is detected from the driver.

It is also possible that the embodiment of FIG. 7 and the embodiment of FIG. 8 are implemented together. Specifically, the display 240 may enlarge the category group in which the area directed by the driver's line of sight is displayed, and may place the cursor S in the enlarged category group.

According to the above-described display device, the driver can quickly input a control command to the display device during operation.

In addition, accuracy can be improved more than simply obtaining a line-of-sight vector and inputting a control command. Since the driver's gaze includes meaningless information, inputting it directly to the control command is highly likely to cause an error. However, the above-described display device can increase the accuracy of the control command received from the driver by confirming the category group corresponding to the driver's gaze vector and receiving the icon selection command through the input unit.

The function corresponding to the finally selected icon can be executed. (550)

10 is a flowchart of a method of controlling a display device for a vehicle according to another embodiment.

First, the pupil center and the eyeball center of the driver can be obtained (600). To do this, the driver's eyeball can be captured using the camera 220.

(610) Specifically, when the coordinate axes are set around the center of the driver's eye, the coordinates of the center of the pupil become the position vector of the driver's gaze . This is the same as described in FIG.

Next, the display position corresponding to the driver's gaze vector can be obtained (620). Here, the position of the display 240 corresponding to the gaze vector means a position in the display area of the display 240 to which the gaze vector is directed.

The cursor can be positioned on any one of the icons belonging to the category group displayed at the thus obtained display position. (630) Next, an icon selection command can be input (640) from the user, The time required for the user to select the icon can be shortened because the icon is moved to the icon in the category group to which the icon is intended to belong.

The function corresponding to the finally selected icon can be executed. (650)

11 is a flowchart of a method of controlling a display device for a vehicle according to another embodiment.

First, the pupil center and the eyeball center of the driver can be obtained. (700) For this purpose, the operator's eyeball can be captured using the camera 220. [

(710) Specifically, when the coordinate axes are set around the center of the driver's eye, the coordinates of the center of the pupil become the position vector of the driver's gaze . This is the same as described in FIG.

Next, the display position corresponding to the driver's gaze vector can be obtained. (720) Here, the position of the display 240 corresponding to the gaze vector means the position in the display area of the display 240 to which the gaze vector is directed.

The category group displayed at the thus obtained display position can be highlighted and displayed. (730) For example, a highlight effect can be added to the category group.

After the operator identifies the highlighted category group, the operator may enter a category group selection command (740). In other words, if an enlargement of the highlighted category group is desired, the driver may enter a selection command for that category group.

(750) Next, an icon selection command can be input (760) from the user. Since the category group is enlarged, the user selects an icon The time required can be shortened.

The function corresponding to the last selected icon can be executed. (770)
