In addition, the spatial remote controller 100 receives information corresponding to the transmitted signal transmitted from the first display apparatus 200. In this case, the information corresponding to the transmitted signal is the coordinate value information of the pointer displayed on the first display apparatus 200 based on the information on the operation of the spatial remote controller 100.

The user input unit 120 may be configured as a keypad or a button. The user may input a command related to the first display apparatus 200 to the spatial remote controller 100 by manipulating the user input unit 120. When the user input unit 120 includes a hard key button, the user may input a command related to the first display apparatus 200 to the spatial remote controller 100 through a push operation of the hard key button.

The pointer of can be displayed.

Accordingly, since the sub display apparatus receives only the coordinate values of the spatial remote controller, the sub display apparatus can compensate for the positional deviation of the main display apparatus and the pointer displayed on the sub display apparatus according to the movement of the spatial remote controller 100.

Referring to FIG. 3, the spatial remote controller 100 is illustrated as having a plurality of buttons. However, only one or two buttons may be provided in the spatial remote controller 100 as needed.

As shown in FIG. 4, when the user moves the spatial remote controller 100 to the left side, the pointer 300 displayed on the first display apparatus 200 also moves to the left side correspondingly. To this end, the spatial remote controller 100 is provided with a sensor unit 130 that can determine the movement, the spatial remote control 100 is a first display information on the movement detected through the sensor unit 130 Send to device 200. The first display apparatus 200 determines the operation of the spatial remote controller 100 from the information about the movement of the spatial remote controller 100, and calculates a coordinate value of the pointer 400 corresponding thereto.

3 and 4 illustrate an example in which the pointer 400 displayed on the first display apparatus 200 moves in response to up, down, left, or right rotation of the spatial remote controller 100. That is, the movement trajectory of the pointer 400 according to the case where the spatial remote controller 100 is moved in the left-direction is described. Here, the moving speed or the moving direction of the pointer 400 may correspond to the moving speed or the moving direction of the spatial remote controller 100.

In the present embodiment, the pointer displayed on the first display apparatus 200 is set to move in response to the operation of the spatial remote controller 100. As another example, a predetermined command may be input to the first display apparatus 200 in response to the operation of the spatial remote controller 100. That is, when the spatial remote controller 100 moves back and forth, the size of the image displayed on the first display apparatus 200 may be enlarged or reduced. Therefore, this embodiment does not limit the scope of the present invention.

In conclusion, the front surface of the spatial remote controller 100 is moved on a virtual plane (VP) by a user. That is, the front surface of the spatial remote controller 100 can be moved in an up-direction, down-direction, left-direction, right-direction, or a combination thereof (for example, left-up-direction) by the user on the virtual plane. Do.

Accordingly, when the front surface of the spatial remote controller 100 is moved on the virtual plane, the pointer displayed on the display screen is moved in the same direction as the front surface of the spatial remote controller 100 is moved. For example, when the user moves the front of the spatial remote control 100 in the up-direction on the virtual plane, the pointer also moves in the up-direction, and the user moves the front of the spatial remote control 100 in the left-up direction on the virtual plane. The pointer will move in the upper-left direction.

The receiving module 251 may include an RF module 252 and an IR module 253, thereby transmitting and receiving a signal wirelessly with the wireless communication unit 110 of the spatial remote controller. In addition, through the IR module 112, the spatial remote controller 100 may receive a signal transmitted according to the IR communication standard.

The coordinate value calculator 254 corrects a hand shake or an error from a signal corresponding to an operation of the spatial remote controller 100 received through the wireless communication unit 110, and coordinate values (x, y) of a pointer to be displayed on the display unit 230. ) Can be calculated.

In addition, a transmission signal of the spatial remote controller 100 input to the first display apparatus 200 through the interface unit 250 is transmitted to the controller 260.

That is, when the first display apparatus 200 and the second display apparatus 300 have the same resolution, the controller 320 displays the pointer of the spatial remote controller 100 at the same position as the transmitted coordinate value. Be sure to

However, when the first display device and the second display device have different resolutions, the controller 320 checks a pointer position corresponding to the transmitted coordinate value according to the difference between the two resolutions.

For example, when the resolution of the first display device is (10, 10), the coordinate value is (2, 2), and the resolution of the second display device is (20, 20), the control unit 320 Rather than determining (2,2) as the location where the pointer is to be displayed, it determines (4,4) as the location where the pointer is to be displayed according to the difference between the two resolutions.

Each of the device's address information is separately stored (step 102).

The sensor unit 130 detects the movement of the spatial remote controller 100, and accordingly detects the movement of the spatial remote controller 100 and transmits the motion information to the controller 170 according to the movement of the spatial remote controller 100 (step 103).

When the motion information is transmitted from the sensor unit 130, the controller 170 transmits the motion information regarding the operation of the spatial remote controller 100 to the main display apparatus (step 104). That is, the controller 170 transmits a signal sensed by the sensor unit 130 to the main display device by referring to the address information of the main display device stored in the storage unit 160. In this case, the signal is transmitted to the main display device through the wireless communication unit 110.

After transmitting the motion information, the controller 170 determines whether coordinate value information about the pointer of the spatial remote controller 100 has been transmitted from the main display apparatus in step 105.

When the controller 105 receives coordinate value information about the pointer of the spatial remote controller 100 transmitted from the main display apparatus, the controller 105 transmits the received coordinate value information to the sub display apparatus (step 106). That is, the controller 105 transmits the coordinate value information transmitted from the main display apparatus to the subdisplay apparatus by referring to the address information of the subdisplay apparatus stored in the storage 160.

9 is a flowchart illustrating a step-by-step control method of a first display apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 9, in the first method of controlling the display apparatus, when motion information regarding the operation of the spatial remote controller 100 transmitted from the spatial remote controller 100 is received through the interface unit 250 (step 201), The coordinate value calculator 254 calculates a coordinate value on which the pointer of the spatial remote controller 100 is to be displayed based on the received motion information (step 202). That is, the coordinate value calculator 254 corrects the shaking or error from the signal corresponding to the operation of the spatial remote controller 100 transmitted through the wireless communication unit 110 to adjust the coordinate value (x) of the pointer to be displayed on the display unit 230. , y)

When a coordinate value is calculated through the coordinate value calculator 254, the controller 260 causes the display unit 230 to display a pointer of the spatial remote controller 100 at a corresponding position of the calculated coordinate value (203). step).

The controller 260 transmits the calculated coordinate value information and the resolution information of the first display apparatus to the outside (step 204). In this case, the controller 260 may transmit the coordinate value and the resolution information to the spatial remote controller 100, or may directly transmit the coordinate value and the resolution information to the second display device connected to the first display device.

10 is a flowchart illustrating a step-by-step control method of a second display apparatus according to an embodiment of the present invention.

Referring to FIG. 10, in the control method of the second display apparatus, first, the controller 320 determines whether coordinate value information transmitted from the outside through the interface unit 310 is received (step 301). In this case, the coordinate value information may be transmitted through the spatial remote controller 100, or may be transmitted from another display device connected to the second display device. In addition to the coordinate value information, the transmitted information includes resolution information of the main display apparatus to which motion information of the spatial remote controller 100 is transmitted.

The controller 320 calculates a pointer position of the spatial remote controller 100 to be displayed through the display unit 330 of the second display apparatus 300 using the transmitted coordinate value information and resolution information (step 302). . That is, if the resolution of the first display device and the resolution of the second display device are the same, the controller 320 causes the pointer of the spatial remote controller to be displayed at the same position of the received coordinate value. However, when the resolutions are different from each other after the resolution is determined, the control unit 320 calculates the display position of the final pointer by compensating the coordinate values with a resolution change algorithm. For example, when the resolution of the first display device is 1920 * 1080, the resolution of the second display device is 1366 * 768, and the coordinate values transmitted from the first display device are x: 100 and y: 200, The controller 320 compensates the coordinate value by the ratio of the resolution. That is, by compensating the coordinate values as x = 100 * 0.711 = 71.1 and y = 200 * 0.711 = 142.2, the final coordinate values to be displayed are calculated as x: 71.1 and y: 142.2.

The controller 320 causes the pointer of the spatial remote controller 100 to be displayed on the coordinate value of the display unit 330 calculated as described above (step 303).
