It is required to develop a convenient remote control device, for example, a pointing device, in accordance with the expansion of a smart TV having various functions.

The video display device has three characteristics as compared with other electronic devices: a large screen, a passive viewer, and a GUI simpler than a PC. Therefore, it is inappropriate to use the touch, mouse, and optical trackpad (OTP) methods applied to existing PCs and phones.

6 is a diagram showing an example of the operation of the video display apparatus and the remote control apparatus.

The auto-hide function of the launcher (or menu) refers to a function that allows the launcher (or menu), which is not displayed, to be displayed on the screen according to a predetermined criterion so that the user can click the icon to execute the function.

The conventional automatic hidden launcher bar or menu bar 610 displays a launcher (menu) when the pointer 205 displayed in response to the movement of the pointing device is placed on the screen edge of the display 180 Activated.

This method also causes the menu to be displayed when the user unintentionally places the pointer 205 on the edge.

Particularly, the pointer, which is controlled on the basis of motion, to the remote control device 200 of the image display apparatus 100 easily touches the edge of the screen compared to the mouse, and obstructs the user's TV watching immersion when the launcher is seen.

Accordingly, it is an object of the present invention to provide an image display apparatus and an operation method thereof, which can enhance the accuracy and efficiency of remote control operation, display menus efficiently, and improve the usability of the user.

The present invention analyzes the motion of the remote control device and activates the auto-hidden menu bar only when a predetermined criterion is satisfied. For example, by activating the auto-hide menu bar by tapping the edge of the screen (either up, down, or one of the sides) twice, you can prevent malfunctions and get a familiar and intuitive motion recognition experience from a knock- .

FIGS. 7 and 8 are flowcharts showing an operation method of the image display apparatus according to the embodiment of the present invention. FIGS. 9 to 11 are diagrams for explaining an operation method of the image display apparatus according to an embodiment of the present invention. to be.

7, an operation method of an image display apparatus according to an exemplary embodiment of the present invention may include a method of displaying an image based on a motion of a remote control device 200 on a display 180 according to a command or an operation scene of a user, (S710)

When the motion information is received from the remote controller 200 through the interface unit 250 in step S720, the controller 170 controls the pointer to move and display the pointer on the basis of the motion information.

Meanwhile, the controller 170 may control the storage unit 140 to store the received motion information and / or pointer movement information.

When the pointer is moved to a predetermined line of the display while operating the pointer using the remote control device 200 in operation S740, the controller 170 controls the operation of the remote controller 200, And analyzes the motion information (S750).

Here, the predetermined line may be one of upper, lower, left, and right outermost boundaries of the display 180. For example, when a line connecting the lowermost end of the display 180 in the horizontal direction is the outermost perimeter of the display 180 and the pointer reaches the outermost perimeter of the display 180, The motion information of the remote control device and the movement information of the pointer for a predetermined time are analyzed.

If the motion information of the remote control device satisfies a predetermined criterion (S760), the controller 170 activates a menu bar that is not displayed and displays it on the display 180 (S770)

On the other hand, the control unit 170 can control to display the menu bar adjacent to the predetermined line. For example, when the pointer reaches the outermost outline of the lower end and satisfies a predetermined criterion, the menu bar is displayed on the lower end area of the display 180. When the pointer reaches the outermost outline on the right side, Can be displayed in the right area of the display 180. [

The predetermined criterion may include a first condition that a maximum value of a first axis coordinate of the pointer is greater than a reference value for a predetermined time, a second coordinate value of the pointer for the predetermined time, And a second condition that the second axis coordinate value of the moved predetermined line is within a predetermined distance.

The predetermined criterion may further include a third condition for an acceleration change of the remote control device during the predetermined time.

8, the image display apparatus 100 receives motion information from the remote controller 200, and monitors movement of the remote controller, change in acceleration, position of the pointer, etc. (S810)

When the pointer moves to a predetermined line of the display, the controller 170 analyzes motion information of the remote control device and movement information of the pointer for a predetermined time before arrival to determine whether the reference is satisfied .

Hereinafter, the case where the pointer moves at the bottom of the screen of the display 180 will be mainly described, but the present invention is not limited thereto.

X_MIN and X_MAX are the minimum and maximum values of the X-axis coordinate of the screen of the display 180, Y_MIN and Y_MAX are the minimum and maximum values of the Y-coordinate of the screen, respectively. In this specification, The lower left corner is illustrated by the minimum value (X_MIN, Y_MIN).

PX represents the X coordinate current value of the pointer, and PY represents the Y coordinate current value of the pointer.

If the pointer moves to the bottom of the screen of the display 180, the Y coordinate of the current coordinate PX of the pointer becomes Y_MIN (S820)

In this case, the controller 170 analyzes the movement of the remote control device and the pointer for a predetermined period of time in the past (S830)

First, the controller 170 may determine whether the maximum value of the first axis coordinate of the pointer for the predetermined time, which is the first condition, is greater than the reference value (S840)

In FIG. 8, PX_MAX and PX_MIN represent the maximum and minimum values of the X coordinate of the pointer in the past period, and PY_MAX and PY_MIN represent the maximum and minimum values of the Y coordinate of the pointer during the past period. DT1 is the minimum movement threshold of the pointer Y axis direction, and DT2 is the maximum range threshold value of the pointer X axis direction.

In addition, the controller 170 determines whether the second axis coordinate value of the pointer for the predetermined time, which is the second condition, and the second axis coordinate value of the predetermined line to which the pointer has moved is within a predetermined distance (S850)

On the other hand, in the present embodiment, the first axis is the Y axis and the second axis is the X axis because the bottom of the screen is described as the center. In the case of the left and right sides, the first axis will be the X axis and the second axis will be the Y axis.

If both of the first and second conditions are satisfied, the controller 170 determines that the user hits the lower end of the display 180 and controls the display 180 to display the menu bar (S870)

The first and second conditions are conditions based on a position on a predetermined line where the pointer reaches.

Referring to FIG. 10, the first condition is a condition that the height of the pointer before the hit when the pointer reaches a predetermined line is equal to or greater than a predetermined value R, and the second condition is a condition that the hit is not made at a place far away from the hit.

That is, the first condition is that the difference between the Y coordinate value (the minimum value in this case) of the hit position 1010 and the y coordinate maximum value within a predetermined time must be larger than R. [

The second condition is that the X coordinate value of the impact position 1010 should be within a predetermined value within a predetermined time. That is, the pointer must be moved within the predetermined interval E.

According to an embodiment, a menu bar may be displayed when the acceleration variation of the remote control device 200 satisfies a pattern of a predetermined third condition (S860).

11 is a graph showing an ideal acceleration graph when the user moves the remote control device 200 once up and down. The third condition may be set to a case where the magnitude of the maximum acceleration (a) in the striking period T1 among the striking period T1 and the return period T2 is equal to or greater than the reference value and the sign of acceleration changes.

On the other hand, if any one of the above conditions is not satisfied, the control unit 170 may determine that the batting recognition has failed and terminate the analysis (S880)

Meanwhile, the predetermined criterion may be that the input satisfying the first condition and the second condition is recognized twice within the reference time. Alternatively, the predetermined criterion may be that the input satisfying the first condition to the third condition is recognized twice within the reference time.

That is, the control unit 170 can control the display of the menu bar when the hit is made twice.

FIG. 12 is a flowchart illustrating an operation method of an image display apparatus according to an embodiment of the present invention, and FIGS. 13 to 15 are diagrams for explaining an operation method of an image display apparatus according to an embodiment of the present invention. In Fig. 12, knocking is performed twice when hit is abbreviated.

Referring to FIGS. 12 and 13, when the pointer reaches a predetermined line at the bottom of the screen, the controller 170 recognizes the bottom hit P1 of the screen (S1210) and determines whether or not the hit satisfies predetermined conditions. (S1220) Furthermore, the control unit 170 can count and manage one hit recognition per a predetermined time.

In addition, the controller 170 recognizes the second screen hit (P2) of the second screen (S1230), and determines whether or not it is hit satisfying predetermined conditions (S1240)

In this case, the controller 170 can determine whether the first and second strikes P1 and P2 satisfy predetermined conditions (S1250 and S1260)

The controller 170 may determine whether the primary hit recognition time T1 and the secondary hit recognition time T2 have been performed within the batting time interval threshold value T. In operation S1250,

In addition, the predetermined reference may be such that the difference between the second axis coordinate values of the two inputs recognized is within a predetermined distance (S1260)

The controller 170 can determine whether the primary blow X coordinate X1 and the secondary blow X coordinate X2 are smaller than the batting position difference threshold value D at step S1250.

That is, if the two strokes are performed at a similar position within a short time, the controller 170 can determine that the two strokes are valid (S1270), and display the menu bar .

14 shows an example in which two legitimate hit inputs 1410 and 1420 are recognized in the lower line of the screen and the menu bar 1430 is displayed at the lower end of the screen. The menu bar 1430 may include menus for manipulating the image display. In addition, the menu bar 1430 may be arranged with a plurality of available applications.

Meanwhile, if the two strokes are not performed at a similar position within a short time, the controller 170 determines that the remote control device is erroneously operated by the user,

In the above example, the case where the pointer moves at the bottom of the screen of the display 180 will be mainly described, but the present invention is not limited thereto.

For example, if there are inputs 1510 and 1520 satisfying two conditions on the left side of the display 180 as shown in FIG. 15, the menu bar 1530 can be displayed on the left side.

The image display apparatus and the operation method thereof according to the present invention are not limited to the configuration and method of the embodiments described above but the embodiments can be applied to all or some of the embodiments May be selectively combined.
