The control bar may be movable only in a specific direction, depending on the property of the object. In general, if the control of the object for adjusting the screen brightness, sound volume, etc. is displayed to be movable in the left and right directions (horizontal direction). In this case, only the left and right directions and the X-axis motion information are extracted from the free three-dimensional motion patterns of the spatial remote control, and the control bar is moved in parallel with the x-axis and displayed.

That is, according to the attributes of the object, by moving the control bar based on the motion information in a specific direction of the three-dimensional motion pattern, it is possible to quickly respond to the user's command, and further enhance the user's convenience.

In addition, in an embodiment of the present invention, the user may manipulate the spatial remote control 201 such that the pointer 202 is positioned on the control bar of the progressive bar or the scroll bar, and then drag the control bar while operating the OK button. When the image display apparatus 100 detects the operation of the OK button, the pointer 202 moves in response to the direction according to the property of the object such as up, down, left, and right.

Accordingly, when the user moves the control remotely to the left or right while moving the control bar to the left or right a little, it is possible to prevent the display position of the pointer 202 from the control bar. As another example, even if the user moves the control remotely up and down while moving the control bar up and down a little, the pointer 202 may prevent the display position from moving out of the control bar.

If the image display apparatus does not know the property of the object, the controller may further include determining a movement property of the control bar. The currently active object UI component checks the desired motion information (vertical, horizontal or rotational information).

In addition, the controller may move the control bar to be displayed on the display only when the extracted motion information is greater than or equal to a threshold. By setting the threshold value, it is possible to prevent malfunction due to trembling or the like that is not desired by the user.

In FIG. 5B, the space remote control 201 moves in the up and down direction y and the left and right directions x.

When it is determined that the movement pattern of the spatial remote controller 201 corresponds to a signal capable of moving the control bar 320 of the object 310 displayed on the display 170 of the image display apparatus 100, the first of the signals The motion information corresponding to the direction is extracted. In this embodiment, the first direction is the left and right directions x.

Disregarding the vertical shift values and the left and right shift values constituting the movement pattern of the spatial remote control 201 irrelevant to the attributes of the specific object are ignored. In the present embodiment, the image display apparatus 100 ignores the vertical shift value of the spatial remote control 201 according to the characteristics of the volume control object controlled in the left and right directions.

As illustrated in FIG. 5C, the image display apparatus 100 moves and displays the control bar 320 based on only the left and right (x) movement information of the extracted spatial remote control 201. By displaying the moving state of the object 310 and moving the control bar 320 in detail, only the movement and coordinate change of one axis direction desired by the object can be quickly responded to a user's command.

In addition, as described above, when a specific object is displayed, not only an embodiment of switching to an input mode for a specific object but also a command for changing a display state of the object when a predetermined button is operated together, and similarly to the first direction. The control bar 320 may be moved and displayed only by the movement information on.

That is, after the pointer of the spatial remote control 201 is positioned on the control bar 320 of the scroll bar 330, the OK button of the spatial remote control 201 may be operated. In this case, the control bar 320 is selected. The user may move the spatial remote control 201 as shown in FIG. 5B while operating the OK button. In FIG. 5B, the space remote control 201 moves in the up and down direction y and the left and right directions x. When the image display apparatus 100 determines that the movement pattern of the spatial remote controller 201 corresponds to a command for changing the display state of the predetermined region of the display 170 and the OK button is operated, the image display apparatus 100 configures the movement pattern of the spatial remote controller 201. Disregard the upper and lower side shift values and the left and right side shift values irrelevant to the property of a specific object. In the present embodiment, the image display device 100 ignores the vertical shift value of the spatial remote control 201 due to the characteristics of the volume control object controlled in the left and right directions.

The video display device 100 moves the pointer 202 so as to correspond to the left and right (x) shift values of the spatial remote controller 201. In addition, when the user continues to operate the OK button of the space remote control 201, the control bar 320 is also moved. In this case, when the user moves the control remotely 320 to the left and right while moving the space remote control 201 slightly up and down due to the shaking, it is possible to prevent the display position of the pointer 202 is out of the control bar or malfunction.

6 is a flowchart illustrating a flow of a method of operating an image display apparatus according to an embodiment of the present invention. More specifically, the present invention relates to a method of providing a visual effect to a user to intuitively recognize and use UI properties of an object.

Unlike the embodiment described with reference to FIG. 4, an object including a control bar movable in the first direction is displayed on the display 170 (S610), and the shape of a pointer corresponding to the movement of the spatial remote control 201 is changed. Step S620 is further included.

When the pointer moves to an area where the object is displayed or to an area adjacent to the object, or when the pointer moves to an area where the control bar is displayed or to an area adjacent to the control bar, the controller changes the shape of the pointer. The user may be informed that the display state of the object is changed, that is, the state in which the control bar can move in the first direction.

In addition, it is more preferable that the changed pointer shape is shaped to intuitively recognize the UI property of the object.

Also, in the displaying of the object, when the object is displayed, the shape of the pointer corresponding to the movement of the spatial remote controller may be changed depending on the object. In this case, it will be more effective when the signal is set to recognize the signal including the movement pattern of the spatial remote control automatically when the specific object is displayed.

That is, by changing the shape of the pointer, the user may intuitively recognize the UI property of the object, more specifically, the moving direction of the control bar, and a setting state regarding a command for changing the display state of the object.

The subsequent steps are the same as described in FIG. The controller 180 determines whether the determined movement pattern of the spatial remote controller 201 corresponds to a command that can be input to the image display apparatus 100, and more specifically, corresponds to a signal capable of moving the control bar (S630). ).

If it is determined that the movement pattern of the spatial remote controller 201 corresponds to a signal capable of moving the control bar of the object displayed on the display 170 of the image display apparatus 100, the controller 180 may control the first of the signals. Motion information corresponding to one direction is extracted (S640).

The control bar is moved and displayed based on the extracted motion information (S650). In the moving and displaying of the control bar, the controller may determine the degree of movement of the control bar by multiplying the extracted motion information by a scale factor. In order to precisely adjust the moving speed, the moving distance, etc. of the control bar, an appropriate weight scale factor is reflected.

7 to 10 are views for explaining the operation method of the image display device according to an embodiment of the present invention. In more detail is a view showing various embodiments of the shape change effect of the pointer.

Referring to FIG. 7A, an object 310 including a control bar 320 that is movable in a first direction is displayed.

The object 310 may further include a scroll bar 330 in which a predetermined scale unit that can indicate an absolute and relative degree of movement of the control bar 320 is displayed. The controller 180 may transmit a signal for controlling the spatial remote controller to output the vibration to the spatial remote controller whenever the control bar passes the scale unit. The user may receive feedback by tactilely sensing and moving the control bar, thereby increasing usability.

As shown in FIG. 7A, when the pointer 410 moves to an area where the control bar 320 is displayed or to an adjacent area, the shape of the pointer 410 is changed and displayed.

7B illustrates a pointer 420 having a left and right arrow shape that intuitively displays the characteristics of the control bar 320 that is movable in the left and right directions.

When the display state change process of the object and the movement of the control bar 320 are finished, the shape of the pointer 410 is restored to the original shape as shown in FIG. 7C.

FIG. 8 illustrates a pointer 430 having an up and down arrow shape in which the control bar 320 intuitively represents a UI property of an object 310 that is scrollable in an up and down direction. The control bar 320 may change the volume, brightness, etc. of the image display device by moving as shown in FIG. 7, or as shown in FIG. 8, an item for executing a function when the user inputs a separate key. It may be.
