BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. It should be understood, however, that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, the same reference numbers are used throughout the specification to refer to the same or like parts.

Throughout this specification, when an element is referred to as "including " an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise.

The multi-display control device may convert the position and angle of placement of the one or more display devices to correspond to the user's position, viewing distance, and field of view. Further, the multi-display control apparatus can divide the content according to the arrangement position and angle of the at least one display apparatus, and continuously provide the content without any portion of the content in each display apparatus. Accordingly, the user can feel immersion and realism. Here, the at least one display device may include a display panel and a speaker, respectively. A detailed description will be given later.

1 is a view for explaining contents of a virtual space provided in a multi-display control apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a content can represent virtual spatial structure type information through a standardized rule-based language syntax structure. The upper part of FIG. 1 is an example of expressing virtual spatial structure type information through a standardized rule-based language syntax structure. Also, the content may be a three-dimensional content expressing virtual spatial structure type information through a standardized rule-based language syntax structure. This can be confirmed in the lower part of Fig.

FIG. 2 illustrates a multi-display control apparatus for providing the contents of a virtual space according to an embodiment of the present invention in the same manner as an actual space. 2, the multi-display control apparatus 500 includes a boundary area setting unit 510, a virtual space configuration unit 520, an actual space configuration unit 530, a storage unit 540, a matching unit 550, And a display control unit 560.

The multi-display control apparatus 500 reads and controls information of a virtual space and an actual space, and the virtual space means a space in which the above-described contents are implemented, and includes one or more objects. The avatar may exist in the virtual space and the avatar may be the subject of the virtual space corresponding to the user of the actual space. The actual space is a space in which one or more display devices are installed. The user's motion state using the display device is detected, and actual spatial information and user information can be generated based on the motion state.

First, the boundary area setting unit 510 obtains the edge position information of the object around the avatar at an arbitrary position in the virtual environment, and sets the boundary area. That is, it is possible to extract the elements that can constitute the boundary of the space in the constituent elements of the contents, and to generate the template shape through the detailed space type analysis. According to an embodiment of the present invention, the boundary area setting unit 510 obtains the position information of the object with the avatar as the center, calculates the position coordinates of the edges of each object, and sets the coordinates of the minimum or maximum coordinates . Then, an area is created following the corresponding point, and the area is rotated by 1 degree around the avatar to set the area having the smallest area as the boundary area. That is, the minimum width boundary area is set.

FIG. 3 illustrates a process of setting a boundary area by the boundary area setting unit 510 according to another embodiment of the present invention.

3, according to another embodiment of the present invention, the coordinates of the coordinates of the edges of the object may be represented by the x-axis and the y-axis. The boundary region setting unit 510 sets the minimum x The coordinate values (x1, x3, x5), the maximum x coordinate values (x2, x4, x6), the minimum y coordinate values (y1, y3, y5), and the maximum y coordinate values Can be obtained. Then, when creating the area following the corresponding point, a rectangular area with the above-mentioned four coordinates is generated, and the area is rotated by 1 degree around the avatar 511 to obtain the area (x5, x6, y5 , y6) can be set as a border area. However, if the corresponding area is rectangular, the area having the smallest area can be set as the boundary area by rotating the avatar 511 at an angle of 0 degree to 89 degrees.

Referring again to FIG. 2, the virtual space configuration unit 520 creates a virtual space in which an object area indicating an area where an object is located in the boundary area is set. According to an embodiment of the present invention, the virtual space configuration unit 520 divides a set boundary area into unit areas (for example, grid), and sets an object area of the boundary area to create a virtual space.

According to an embodiment of the present invention, the virtual space configuration unit 520 moves a unit area of a boundary region (hereinafter, referred to as a grid as an example) by units based on the position of the avatar 511, And determines an object area based on the determination. That is, it determines whether an object exists or does not exist for each lattice of the latticed boundary area and displays it.

More specifically, the virtual space configuration unit 520 determines the presence or absence of an object in a boundary area of a virtual space using a flood-fill algorithm. The flood-fill algorithm is a bitmap image The object is recognized as an object except for the background (or bottom) from the file, and the presence or absence of the object is determined based on the position of the avatar 511, moving in units of lattice from east to west, south and north. If there is an object, the virtual space configuration unit 520 indicates that the object exists (for example, indicated by 0 or 1). If not, the virtual space configuration unit 520 continues to determine the presence or absence of the object by applying the flood-fill algorithm. At this time, the boundary area in which the presence or absence of the object is indicated is called a virtual space, the virtual space is set in a lattice unit, and the parameters can be changed so as to adjust the minimum unit lattice and recognition scale of the flood-fill algorithm.

FIG. 4 shows a result of determining whether an object in the virtual space is determined using the flood-fill algorithm according to an embodiment of the present invention.

That is, Fig. 5 shows an example of the space type.

The storage unit 540 stores one or more spatial types generated in the actual spatial configuration unit 530. The matching unit 550 invokes the type of space stored in the storage unit 530 and performs an operation to be described later.

Referring again to FIG. 2, the matching unit 550 matches the space type having the object region most similar to the virtual space to the virtual space. More specifically, the matching unit 550 mutually matches the space types in which the object areas most coincide with each other through the lattice unit comparison with the virtual space. The grid unit comparison is made by comparing the unit area (for example, the grid) of the virtual space with the grid of the space type one by one and checking how much they match.

FIG. 6 shows an example of matching a space type having an object region most similar to a virtual space.

Referring again to FIG. 2, the display control unit 560 adjusts the angle and position of the at least one display device based on the virtual space matching the actual space around the current user. That is, in order to provide the augmented reality to the user, the display control unit 560 operates the display device so that the virtual space felt by the user changes according to the position of the user. Some of the one or more display devices can be arranged in a fixed form, and the remaining part can be arranged in the form of a sliding door and a sliding door so that the angle and the position can be adjusted.

9 shows a flowchart of a method of controlling a multi-display for providing contents using one or more display devices according to an embodiment of the present invention.

First, corner position information of an object around an avatar at an arbitrary position in a virtual environment is acquired to set a boundary area (S110). The step of setting the boundary region may include the steps of obtaining positional information of the corner of the object around the avatar, calculating coordinates of each corner, finding a point having the coordinates of the minimum or maximum among the coordinates of the calculated corner, And rotating the area formed using the found point by 1 degree around the avatar to set the area having the smallest area as the boundary area.

More specifically, when the coordinates of the corner of the object are expressed by the x-axis and the y-axis, the multi-display control device calculates the minimum x-coordinate value, the maximum x-coordinate value, And a point having a maximum y coordinate value. When creating the area following the corresponding point, a rectangular area having the above-mentioned four coordinates is generated, and the area having the smallest area can be set as the boundary area by rotating the area by 1 degree around the avatar. However, if the area is rectangular, the region where the smallest area appears can be set as the boundary area by rotating the avatar at an angle of 0 degree or more and 89 degrees or less.

Next, a virtual space in which an object area indicating an area where the object is located is set in the boundary area. According to an embodiment of the present invention, the multi-display control apparatus divides a set boundary region into unit regions (for example, divided into a grid), sets an object region of the set boundary region, and creates a virtual space (S120) . That is, the multi-display control apparatus moves the grid of the bordered lattice by one unit around the position of the avatar, determines the presence or absence of the object, and displays it on the grid. Therefore, a virtual space in which the object area is set is created. The related detailed description has been described above with reference to Fig. 4, and is omitted.

Next, one or more space types are created according to the pattern of the actual space in which the display device is installed. According to an embodiment of the present invention, the multi-display control apparatus divides an actual space into unit areas (e.g., grid) to generate a spatial type (S130). The spatial type of the latticed real space can include five forms: square, street, narrow space, 'a', and mirror 'a'. The detailed description related to this is described above with reference to FIG.

Next, a space type having an object area similar to the virtual space in which the object area is displayed is matched to the virtual space (S140). By comparing the stored space types and the virtual space in a lattice unit, that is, by comparing the lattices one by one, the space type having the most matching object area is matched to the virtual space according to whether the object exists in the corresponding lattice. The matched result can be stored in the multi-display control device.

Finally, the multi-display control device adjusts the angle and position of the display device (S150). That is, a space type for the surrounding environment of the current position of the user is found, and the boundary area of the matched virtual space is displayed on the display device.

A multi-display control apparatus and method for providing such a content in a virtual space in the same manner as a real space provides a virtual space on the basis of an avatar in a virtual environment, There is a technical significance in that the user can feel the immersive feeling and the sense of reality by providing the content of the virtual space by matching the same and adjusting the position and angle of the display device according to the user.

However, the method of providing the contents of the virtual space according to the present invention in the same manner as the actual space can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording media storing data that can be decoded by a computer system. For example, it may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, or the like. In addition, the computer-readable recording medium may be distributed and executed in a computer system connected to a computer network, and may be stored and executed as a code readable in a distributed manner.

One embodiment of the present invention may also be embodied in the form of a recording medium including instructions executable by a computer, such as program modules, being executed by a computer. Computer readable media can be any available media that can be accessed by a computer and includes both volatile and nonvolatile media, removable and non-removable media. In addition, the computer-readable medium may include both computer storage media and communication media. Computer storage media includes both volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data. Communication media typically includes any information delivery media, including computer readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave, or other transport mechanism.
