According to the method of recognizing a cube pattern according to an embodiment of the present invention, in the step of recognizing the cup pattern shown in FIG. 7 (step S710), the terminal device 200 acquires, from the cube case 800 having the above- And recognizes a pattern formed on the upper surface of the cube 100 that is seated in a specific divided space of the cube case 800 based on the magnetic force information of the received magnetic sensors.

After the terminal device 200 recognizes the pattern type, direction, and position of the cube 100, a method of comparing the target image with the patterns of the cubes to determine whether or not the cube is matched will be described with reference to FIGS. 1 to 7 And therefore, a detailed description thereof will be omitted.

FIG. 16 is a view for explaining an embodiment of a method of recognizing a cube pattern using a near field wireless communication based interactive cube according to the present invention.

Referring to FIG. 16, the patterns of cubes placed by the user in the divided spaces of the cube case 800 are recognized according to positions, The matching result indicating that the target shape has been completed can be displayed on the screen 400 of the terminal device 200. In this case,

According to another embodiment of the present invention, a terminal device automatically performs pairing with a cube case that succeeds a target shape matching among a plurality of cube cases arranged in the vicinity, thereby facilitating connection between a terminal device and a specific cube case .

FIG. 18 is a flowchart illustrating a method of interlocking a cube case according to an embodiment of the present invention. Referring to FIG. 18, a method of connecting a terminal device 200 to one of a plurality of cube cases disposed in the periphery is illustrated.

Referring to FIG. 18, the terminal device 200 displays a target shape having a plurality of patterns (S1800).

The target shape displayed in step S1800 may be a screen shape of the terminal device 200 to specify a cube case to be used by the user among the plurality of cube cases disposed around the terminal device 200, As shown in FIG.

Referring to FIG. 19, a plurality of cube cases 801 to 806 including a cube case that the user is currently using may exist around the terminal device 200.

In this case, the terminal device 200 must establish a connection by attempting to pair with the cube case that the user wants to use among the plurality of cube cases 801 to 806.

20, the terminal device 200 displays the target shape 430 for automatic pairing on the screen 400, and the user places the target shape 430 on the cube case 802 to be used, A plurality of cubes may be arranged so as to be matched with the cube 430.

The terminal device 200 establishes connection with any one of the cube cases disposed in the periphery (step S1810), and then, based on the information received from the connected cube case, (Step S1820).

Thereafter, the terminal device 200 compares the patterns of the recognized cube with the patterns of the target shape displayed in the step S1800, and confirms whether the patterns match the target shape (S1830).

If it is found that the matching with the target shape is successful, the address information such as the Mac address of the cube case is stored and the connection process with the cube case is terminated (S1840).

On the other hand, if it is determined that the matching with the target shape fails, the terminal device 200 repeats steps S1810 to S1830 for neighboring cube cases until matching with the target shape is successful.

For example, the terminal device 200 constructs a list of peripheral cube cases connectable via Bluetooth, and repeats the steps S1810 to S1830 sequentially from the closest cube case among the cube cases included in the list, And matching cube cases.

19, the terminal device 200 may first pair with the nearest first cube case 801 to check whether the cubes arranged in the corresponding cube case match the target shape.

Here, if the cube case to be used by the user is the second cube case 802, matching with the target shape for the first cube case 801 fails.

Thereafter, the terminal device 200 pairs with the second closest second cube case 802 to check whether or not the cubes arranged in the corresponding cube case match the target shape, and when the matching with the target shape is successful, And store the MAC address of the second cube case 802.

If the second cube case 802 is disposed around the terminal device 200 after the MAC address of the second cube case 802 is stored in the terminal device 200 as described above, 2 cube case 802 can be automatically performed and connected to each other.

Meanwhile, in order to recognize the pattern of the cube placed in the cube case and display it at a specific position on the screen 400 of the terminal device 200, the position should be specified for each of the divided spaces of the cube case.

For this purpose, the cube case is provided with a 3-axis geomagnetic sensor, so that the direction of the cube case can be detected through the 3-axis geomagnetic sensor.

The terminal device 200 receives the measurement information detected through the triaxial geomagnetic sensor from the cube case and recognizes the angle of the cube case using the measurement information received from the cube case

Thereafter, the terminal device 200 can detect the upper area of the cube case based on the recognized angle.

Referring to FIG. 21, the terminal 200 receives angular information detected from a cubic geomagnetic sensor through a cubic case 800 disposed in front of the terminal 200, and transmits the angle information to the terminal 200 The angle? Of the cube case 800 as a reference can be calculated.

The angle θ of the calculated cube case 800 may have a value between 0 and 360 degrees and the range of 0 to 360 degrees may be defined in four outer regions of the cube case 800 And can be divided into four corresponding angular regions.

In this case, the outer region T of the cube case 800 corresponding to the angle region including the calculated angle? May be detected as an upper region toward the terminal device 200.

When the upper region T of the cube case 800 is detected as described above, the positions of the divided spaces where the plurality of cubes are seated can be specified based on the detected upper region.

For example, as shown in FIG. 21, the positions of the divided spaces may be sequentially designated starting from the upper left corner with respect to the upper region T of the cube case 800.
