DETAILED DESCRIPTION

Exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of group-controlled smart blocks according to some embodiments of the present disclosure;

As shown in FIG. 1, group-controlled smart blocks according to some embodiments of the present disclosure form a group of n smart blocks each having a unique ID and performing a given function, including a master block 110 assigned by an external control device among the n smart blocks and n-1 slave blocks 120-1, 120-2, 120-3 other than the master block 110.

In some embodiments of the present disclosure, the master block 110 receives a program from the external control device and transmits to each of the n-1 slave blocks 120-1, 120-2, 120-3 a first command for performing a corresponding function.

In some embodiments of the present disclosure, each of the n-1 slave blocks 120-1, 120-2, 120-3 receives the first command from the master block 110 and performs the corresponding function.

Each of the n smart blocks constituting the group-controlled smart blocks according to some embodiments of the present disclosure includes a function unit for performing a corresponding function. Details on such function unit can be found in, for example, Korean Patent No. 10-1714642 and Korean Patent No. 10-1739029.

The function unit of each of the n smart blocks constituting the group-controlled smart blocks according to some embodiments of the present disclosure may include at least one or more of light-emitting function, recording function, display function, sound function, rotational or translational motion function, and the like. In some embodiments of the present disclosure, the master block 110 figures out the function of each of the slave blocks based on the ID of each of the n-1 slave blocks 120-1, 120-2, 120-3 and transmits the first command to cause each of the slave blocks to perform the corresponding function.

In the example shown in FIG. 1, the group-controlled smart blocks include four smart blocks of which one is assigned as the master block 110 and three smart blocks are assigned as the slave blocks 120-1, 120-2, 120-3, however, the number of smart blocks constituting the group-controlled smart blocks can be arbitrarily set and a plurality of master blocks can be assigned as necessary.

In some embodiments of the present disclosure, when a plurality of master blocks is assigned, the slave blocks can be divided into a plurality of sub groups and each of the master blocks can control the slave blocks in one sub group.

In some embodiments of the present disclosure, when a plurality of master blocks is assigned, one of the master blocks can be activated and the rest of the master blocks can stay in stand-by in reserve.

FIG. 2 is a schematic diagram for explaining an operation example of the group-controlled smart blocks according to some embodiments of the present disclosure. FIG. 3 is a schematic diagram for explaining operations of a master block and a slave block for implementing the group-controlled smart blocks according shown in FIG. 2.

In FIG. 2, an example of how the group-controlled smart blocks according to some embodiments is explained in which, in group-controlled smart blocks including four smart blocks, when four smart blocks are combined to form a proper plane, a smile is displayed in a multi-vision format on the plane formed with side plates of the smart blocks.

The complete image shown in FIG. 2 is presented to a user and then the four smart blocks are arbitrarily arranged as shown in FIG. 3. Thereafter, the master block 110 displays a part of the smile on its display 111 and transmits the first command to cause the slave blocks 120-1, 120-2, 120-3 to respectively display corresponding parts of the smile on their displays 121-1, 121-2, 121-3.

Upon receiving the first command from the master block 110, the slave blocks 120-1, 120-2, 120-3 respectively display the corresponding parts of the smile on their displays 121-1, 121-2, 121-3.

When the user completes the puzzle by correctly arranging the four smart blocks arbitrarily arranged, the smile is displayed on the displays 111, 121-1, 121-2, 121-3 in a multi-vision format as shown in FIG. 2.

FIG. 4 is a schematic diagram for explaining another operation example of the group-controlled smart blocks according to some embodiments of the present disclosure. FIG. 5 is a schematic diagram for explaining operations of a master block and a slave block for implementing the group-controlled smart blocks shown in FIG. 4.

In the example shown in FIGS. 4 and 5, the level of difficulty of the puzzle can be increased by displaying the same image or a different image on sides of the smart blocks different from the display 111 of the master block 110 and the displays 121-1, 121-2, 121-3 of the slave blocks 120-1, 120-2, 120-3.

FIGS. 6 and 7 are schematic diagrams for explaining another operation example of the group-controlled smart blocks according to some embodiments of the present disclosure.

In the example shown in FIG. 6, in a group of group-controlled smart blocks including 11 smart blocks, one master block 610 and 10 slave blocks 620-1, 620-2, 620-3, 620-4, 620-5, 620-6, 620-7, 620-8, 620-9, 620-10 respectively display numbers from 0 to 9 on their displays 611, 621-1, 621-2, 621-3, 621-4, 621-5, 621-6, 621-7, 621-8, 620-9, 621-10.

Firstly, numbers displayed on the displays 621-1, 621-2, 621-3, 621-4, 621-5, 621-6, 621-7, 621-8, 620-9, 621-10 of the 10 slave blocks 620-1, 620-2, 620-3, 620-4, 620-5, 620-6, 620-7, 620-8, 620-9, 620-10 are presented to a user, and then the displays 621-1, 621-2, 621-3, 621-4, 621-5, 621-6, 621-7, 621-8, 620-9, 621-10 of the 10 slave blocks 620-1, 620-2, 620-3, 620-4, 620-5, 620-6, 620-7, 620-8, 620-9, 620-10 are turned off or the numbers displayed are changed to “?” as shown in FIG. 7.

Thereafter, the master block 610 displays a hint image on its display 611 (in the example shown in FIG. 7, one of the numbers from 0 to 9), and the user selects a slave block which he or she assumes to correspond to the image displayed on the display 611 of the master block 610 (in the example shown in FIG. 7, the number “0”).

When the user correctly select the slave block corresponding to the image displayed on the display 611 of the master block 610 (in this example, the slave block 620-10), the selected slave block displays the correct number on its display (in this example, the number “0” is displayed on the display 621-10 of the slave block 620-10).

Thereafter, the master block 610 deletes the correctly selected slave block (in this example, the slave block 620-10) from the group, repeats the same procedure for the rest of the slave blocks or leave the correctly selected block as it is and repeats the same procedure to increase the level of difficulty.

In some embodiments of the present disclosure, the master block transmits to each of the n-1 slave blocks a second command for pausing the corresponding function, and upon receiving the second command, the n-1 slave blocks pauses the corresponding function and performs again when a predetermined condition is met.

That is, the master block 610 transmits the first command to cause each of the slave blocks 620-1, 620-2, 620-3, 620-4, 620-5, 620-6, 620-7, 620-8, 620-9, 620-10 to display the corresponding number as shown in FIG. 6, and transmits the second command to cause each of the slave blocks 620-1 , 620-2, 620-3, 620-4, 620-5, 620-6, 620-7, 620-8, 620-9, 620-10 to turn off the corresponding number as shown in FIG. 7.

Turning off the display means to hide the original display, which includes turning off the display itself or displaying an image that has nothing to do with the original display (in the example shown in FIG. 7, “?”).

Thereafter, when a predetermined condition is met (in the example shown in FIG. 7, when the user selects the correct slave block), the corresponding slave block performs its function again (in the example shown in FIG. 7, when the user selects the slave block 620-10, the slave block 620-10 displays the number “0” on the display 621-10 again).

In some embodiments of the present disclosure, the master block 110 transmits the second command to the n-1 slave blocks 120-1, 120-2, 120-3 in a predetermined cycle.

In some embodiments of the present disclosure, the master block 110 transmits the second command to the n-1 slave blocks 120-1, 120-2, 120-3 upon a predetermined condition being met. The predetermined condition in the example shown in FIG. 7 includes the user’s selection of the slave block 620-10, and when this condition is met, the slave block 620-10 displays the number “0” on the display 621-10 again.
