The arrow in the direction opposite to the right arrow 210d of the display device 210 is the left arrow 220c of the display device 220 disposed on the right side of the display device 210. [

6 is an exemplary view showing a state after the user selects the left arrow 220c of the display device 220 corresponding to the right arrow 210d of the display device 210 in the UI image.

6, when the user selects the left arrow 220c of the display device 220 facing the right arrow 210d of the display device 210, the arrow 220c indicates that the first first color To a third color.

Here, the following points are to be noted while the user proceeds the location information setting process.

First, if the two arrows facing each other in opposite directions and facing each other are referred to as a pair of mutually corresponding arrows, the arrows that the user randomly selects from the UI image should be selected from the arrows with corresponding arrows. For example, in the display device 210, the upper arrow 210a and the left arrow 210c do not have corresponding arrows, and the lower arrow 210b and the right arrow 210d have corresponding arrows.

Secondly, with the user arbitrarily selecting the arrow, the user must select the corresponding arrow that faces the previously selected arrow in the next selection step. For example, the corresponding arrow 220c facing the right arrow 210d is selected, and in the next selection step, the arrow 220c facing the arrow 210d selected in the previous step should be selected.

Third, after selecting a pair of corresponding arrows respectively, the user can again select an arbitrary arrow. For example, the user selects the lower arrow 220b of the display device 220 and then selects the upper arrow 250a of the display device 250 corresponding to this lower arrow 220b. The selected arrows 220b and 250a change from the first color to the third color, thereby indicating the selected state.

The UI image may include information including the content of the item so that the user can follow the above-mentioned items.

In this way, when the user performs an operation of selecting all mutually corresponding arrows, the user performs the selection of the arrows 24 times in the 3x3 matrix arrangement structure. At this stage, the UI image appears as shown in FIG.

7 is an exemplary view of a UI image showing a state in which all pairs of arrows corresponding to each other are selected.

As shown in Fig. 7, the remaining selected arrows except for the arrow 210d that the user first selected appear in the third color. Upon completing the operation of selecting all mutually corresponding arrows, the user again selects the arrow 210d that was initially selected. Thus, the arrow 210d changes from the second color to the third color, and the host device 100 determines that the selection process of the arrow by the user is completed by reselecting the first selected arrow 210d.

The first color, the second color, and the third color described above can be applied to any color as long as the mutual distinction between the arrows is possible. In addition, if the selected arrows can be distinguished from each other, various change configurations such as differences in brightness, differences in saturation, differences in style, and differences in shapes can be applied instead of color differences.

When the selection process of the arrow by the user is completed as described above, the host device 100 displays each of the display devices 210, 220, 230, 240, 250, 260, 270, 280 , 290).

Hereinafter, the host device 100 determines the relative positions of the respective display devices 210, 220, 230, 240, 250, 260, 270, 280, and 290 in the 3x3 matrix arrangement based on the selection order of the arrows selected by the user A method of deriving the positional information will be described.

8 is an exemplary view showing position-related information of some display devices 210 and 220 based on the selection process of the arrow of the user.

For example, when the ID of the display device 210 located at the left corner of the 3 × 3 matrix arrangement structure is "ID-E" (see FIG. 3), the host device 100 displays The information as shown in FIG. 8 can be derived based on the selection process of the user. The same principle applies to the other display devices 230, 240, 250, 260, 270, 280, and 290 although only two display devices 210 and 220 are shown in this figure.

In the table of Fig. 8, "ID" means the identification ID of the display device 210, 220, 230, 240, 250, 260, 270, 280 and 290, "selection " , &Quot; correspondence ID "indicates the direction in which the arrows face, and" correspondence ID " indicates the direction in which the corresponding arrow on the display device 210, 220, 230, 240, 250, 260, 270, 280, 290).

In the case of the display device whose ID is " ID-E ", two down arrows and right arrows are selected from among the four directions of up and down and left and right, the correspondence ID to the down arrow is "ID- Is "ID-D ". Here, the IDs of the display devices 210, 220, 230, 240, 250, 260, 270, 280, and 290 are examples of FIG.

In the case of the display device whose ID is "ID-D ", three downward arrows, left arrow and right arrow are selected among the four directions of up and down and left and right directions, the correspondence ID to the down arrow is" ID- ID-E ", and the corresponding ID to the right arrow is "ID-B ".

In this manner, the host apparatus 100 derives positional relationship information for all the display devices 210, 220, 230, 240, 250, 260, 270, 280, and 290. The host apparatus 100 can display the remaining display devices 220, 240, 250, 260, and 280 based on any one of the display devices 210, 230, 270, and 290 located at the vertices of the 3x3 matrix arrangement, The position of each display device 210, 220, 230, 240, 250, 260, 270, 280, and 290 as shown in FIG. 3 is finally determined.

For example, after the host apparatus 100 selects the display apparatus 210 as a reference and specifies the display apparatuses 220 and 240 respectively disposed on the left and lower sides of the display apparatus 210, The display devices 210, 220, 230, 240, 250, 260, 270, and 280 may be configured to display the remaining display devices 230, 250, 260, 270, 280, and 290 on the basis of the display devices 220 and 240. , 290) in the matrix.

The reason why the reference of the relative position is designated to the display device 210, 230, 270, 290 at the vertex of the matrix arrangement is that the display device 210 located at the vertex, regardless of the matrix form of 2x2, 3x3, 2x3, 4x4, (210, 230, 270, 290) is four, it is easy to determine the relative position when it is determined as a reference.
