Hereinafter, a detailed description of each step will be described.

The first user client device 310 creates or executes the first user space 10 (S200). That is, in one embodiment, upon the request of the first user, the first user client device creates a first user space, which is a virtual space in which the first user will place a virtual object, or reconnects to the previously created first user space. run

In one embodiment, the first user space 10 is a virtual space including one or more virtual objects arranged by the first user, and is generated to receive and correspond to image data in the real space as well as the VR virtual space. AR virtual space.

The first user client device changes the location of the first selection target 410 selected by the first user in response to the movement of the first user client device or the manipulation of the first user ( S300 ). The first selection object 410 is a specific object in a first user space selected by the first selection request of the first user, and the first selection request is the first user that can be input to the first user client device. Includes all inputs for a specific object of

In an embodiment, the first selection request may be performed by a first user touching a specific object on the screen of the client device or a second icon in a state where the first icon fixed in an area of the screen is located on the specific object. includes touch.

In one embodiment, the movement of the client device may include not only a movement of changing the position (coordinate) of the client device, but also a change of direction, ie, a rotational movement of the client device.

In an embodiment, the change of the first selection object may include a change in the position of the first selection object in the first user space corresponding to the movement of the client device or the manipulation of the first user, the change of the position of the first selection object from the first position. This includes changing the distance or changing the shape, size, or direction of the first selection object while the position in the first user space is fixed. Hereinafter, it will be described in detail.

In an embodiment, changing the position of the first selection object in the first user space is changing the arrangement position of the first selection object in the first user space, which is a three-dimensional virtual space, wherein the first selection object is In the selected state, the location is changed according to the movement of the first user's client device or the manipulation of the first user. In addition, the arrangement position includes position (coordinate) information as well as arrangement information regarding the direction of the first selection target.

In one embodiment, referring to FIG. 2 , the first selection object 410 maintains a specific distance with respect to a specific direction of the first user client device 310 in the first user space while maintaining the first user client device. may be moved in response to the movement of

For example, when the first selection object is located at a distance of 1 m perpendicular to the center of the rear surface (opposite to the user) of the first user client device, the first selection object is the first user client device by the first user. The position in the first user space may be changed to correspond to the movement (including rotation and position change).

Specifically, referring to FIG. 2 , when the position of the client device 310 is fixed and only the direction is rotated ( 311 , 312 ) or the position is changed ( 312 , 313 ), the position and direction of the first selection object 410 . may be changed (411, 412, 413) to correspond thereto. That is, in this case, there is an effect that the user can easily change the position of the first selection object only by movement (including rotation) of the client device without a separate manipulation of the arrangement of the first selection object.

Meanwhile, the change of the position of the first selection object is not limited thereto, and may be performed by a user's manipulation including a touch or drag, of course. Also, as will be described later, the distance between the first selection target and the first location (eg, the first user client device) may be changed according to a user's manipulation.

Also, in an embodiment, the direction of the first selection target may be fixed with respect to the client device. For example, when the front of the first selection object faces the client device before movement, and the position of the first selection object is moved (411, 412) according to the movement (311, 312) of the client device, the movement The front face of the first selection object after the movement may be automatically rotated to face the client device after movement. Also, in another embodiment, the direction of the selection object may be fixed in the user space and only the location change may be performed according to the movement of the client device. Also, as will be described later, the first selection object is rotatable according to a user's manipulation.

In an embodiment, the first selection object 410 is moved by the first user on a spherical surface at a specific distance from the first location 110 according to the movement of the first user client device or the operation of the first user in the selected state. The position in space may change.

In an embodiment, the first position 110 is calculated from the arrangement position of the first user client device 310 or the arrangement position of the first user client device when the first selection object 410 is selected. and the location of the first user 210 .

FIG. 3 is a diagram for explaining a case in which the first location 110 is the location of the first user 210 calculated from the arrangement location of the first user client device when the first selection object is selected.

Referring to FIG. 3 , in an embodiment, the first position, which is the first user position in the state in which the first selection object is selected, is an arm length of the first user or the first user client from the position of the first user client device. It may be calculated in consideration of the direction and the like.

Also, in an embodiment, since the first position is a first user position in a state in which the first selection object is selected, when the first user moves in a state in which the first selection object is selected, the position of the first user after movement The location may be the first location.

Also, in one embodiment, the first location may include information about the direction as well as the coordinates of the first user or the first user client device. That is, in FIG. 3 , the first location 110 may include the coordinates of the first user 210 , the direction of the first user client device 310 , or the direction of the first user 210 . have.

Also, in one embodiment, referring to FIG. 3 , the first selection object may be moved in the first user space while maintaining a specific direction or a specific distance with respect to the first user client device. For example, when the first user stretches his arm and holds the client device (eg, a smartphone) in his hand, and the first selected object is located at a distance of 1 m orthogonal to the center of the rear surface of the client device, the second When the first user moves (314, 315) the client device 310 with an outstretched arm to place the first selection object at a desired position, the first selection object 410 is moved from the first position, which is the first user position. It may be moved (414, 415) on a sphere of a distance of '1m + first user's arm length'. That is, in this case, in the first spherical coordinate system 510 having the first position 110 as the origin, the first selection object may move on a specific spherical surface in which the r value is '1m + first user's arm length'. Also, it goes without saying that the r value may be changed by the user's arm movement or user manipulation while the first selection object is selected.

FIG. 4 is a diagram for explaining a case where the first location 110 is the arrangement location of the first user client device 310 when the first selection object is selected. Referring to FIG. 4 , according to an embodiment, the first location, which is the location of the first user client device in the state in which the first selection object is selected, may include information about the direction as well as the coordinates of the first user client device. can

Also, since the first position is the arrangement position of the first user client device when the first selection object is selected, when the first user moves the first user client device while the first selection object is selected, The position (including orientation) of the first user client device after movement may be the first position.

In addition, in an embodiment, the first selection object 410 is moved on a spherical surface at a specific distance from the first location according to the movement of the first user client device or the operation of the first user in the selected state. location may change. That is, as shown in FIG. 4 , not only when the position of the client device is changed ( 314 , 315 ), but also when the position is fixed and only the direction is changed ( 314 , 316 ) of the client device, the first selection object is the direction of the client device In response, the location in the first user space may be changed ( 414 , 415 , 416 ).

For example, when the first user extends his arm and holds a client device (eg, a smartphone) in his hand, and the first selected object is positioned at a distance of 1 m orthogonal to the center of the rear surface of the client device , if the first user rotates only the direction of the client device while extending his arm to place the first selection object at a desired position, the first selection object is '1m from the first position, which is the placement position of the first user's client device. It can be moved on the sphere of distance of '. That is, in this case, in the first spherical coordinate system having the first position as the origin, the object may move on a specific spherical surface having an r value of '1m'.

Contrary to this, when the first user moves (including changing or rotating the position) the client device with an outstretched arm to place the first selection object at a desired position, the first position, which is the arrangement position of the moved client device, is the origin. The first selection object may be located at a distance of 1 m orthogonal to the center of the rear surface of the client device on a first spherical coordinate system of . Also, it goes without saying that the r value may be changed by a user manipulation while the first selection object is selected.

Also, in one embodiment, when the location and orientation of the client device and the user are the same (eg VR headset), such as when the user wears the client device on the head without holding the hand, the first location is the client device location Of course, it can be judged by (including direction).

In one embodiment, although not shown in the drawings, receiving and applying change information on the distance between the first location 110 and the first selection object 410 from the first user 210; may include more. As described above, in the first selection object moved on the spherical surface of a specific distance from the first position, the first selection object is moved on the spherical surface of the changed distance by changing the distance.

For example, in FIG. 4 , when the first selection object is located at a distance of 1 m orthogonal to the center of the rear surface (opposite to the user) of the first user client device, the first selection object is displayed at the request of the first user. The distance from the client device may be changed to 2m, and the first selection object may be maintained in the first user space to correspond to the movement including rotation and movement of the client device of the first user by the first user while maintaining it. location may change.

That is, by allowing the user to change the r value, which is the first selection object distance from the origin (eg, the client device), on the first spherical coordinate system having the first position as the origin, it is displayed at all positions in the first user space. It has the effect that it can be freely and easily deployed. In addition, the distance change request includes all inputs for changing the distance of the user's selection target that can be input to the user's client device.

In an embodiment, the request for changing the distance includes dragging a specific icon on the screen of the client device in the vertical direction while the first user has selected the first selection object.

In an embodiment, although not shown in the drawings, the method may further include receiving and applying change information on the first selection object 410 from the first user 210 . Also, in an embodiment, the change information of the first selection object includes change information regarding the shape, size or direction of the first selection object in a state where the position of the first selection object in the first user space is fixed. includes That is, in a state in which a specific object is selected, the user may freely change the shape, size, direction, etc. of the selected object selected by the user's manipulation, and may also upload a new object to change it. In an embodiment, the newly uploaded object information may be received from the server.

In an embodiment, the size change request includes a pinch in/out gesture of the user on the client device in a state in which the first user selects the first selection object.

In an embodiment, the rotation of the selection object includes a roll, yaw, or pitch rotation, and the roll rotation request is a two-finger rotation gesture with respect to the user's client device. , The yaw rotation request includes a pan or swipe gesture in a left and right direction, and the pitch rotation request includes a pan or swipe gesture in a vertical direction.

Also, according to an embodiment, it is possible for the user space forming platform company to receive a predetermined price from the user to expand the type of the virtual object in the user space. That is, when a user desires to arrange more various types or a larger number of objects in the user space, the type or number of objects may be expanded by paying a certain price to the user space forming platform company.

The first selection object is placed in the first user space 10 according to the placement request of the first user 210 for the first selection object 410 (S400). In an embodiment, when the first selection object arrives at a desired location in the first user space by the first user (including moving the client device or the first user's manipulation) while the first selection object is selected , the selection of the first selection object is released according to the placement request of the first user, and the first selection object is arranged in the first user space according to the position and direction of the first selection object when the placement request is made.

In an embodiment, the placed object is no longer moved in the first user space by movement of the client device or by a user manipulation, but may be moved when selected again by the user. In addition, the placement request includes all inputs to the user's selection target that can be input to the user's client device.

In an embodiment, the placement request includes a first user's touch on the client device screen while the first selection object is selected.

In one embodiment, although not shown in the drawings, according to the copy request of the first user for the first selection object, the selection of the first selection object is maintained but the same type, shape, and shape as the first selection object; It further includes; disposing one or more duplicated objects having a size or a direction in the first user space. That is, when the user wants to arrange a plurality of specific selection objects, a plurality of replicated objects can be conveniently arranged by making a copy request for each desired location of the specific selection object without having to go through a process of newly uploading the object.

However, the selection request, arrangement request, distance change request, size change request, rotation request or duplication request according to the present invention are not limited to the above-described embodiment, and include all gestures that can be input to the user's client device.

According to an embodiment of the present invention, the user selects a specific object in the first user space, which is a three-dimensional virtual space, and freely moves the selected object according to the movement of the client device or the user operation, and by simple manipulation By freely adjusting the shape, size, and direction of the selected object, there is an effect that it can be easily arranged in a desired shape, size and direction at a desired location.

Referring to FIG. 5 , the method for forming a virtual space according to another embodiment of the present invention further includes converting first spherical coordinate information of a first selection object 410 into first reference coordinates (S500); do. That is, in one embodiment, the first spherical coordinate information of the first spherical coordinate system having the first position of the arranged first selection object as the origin can be converted into the first reference coordinates with respect to the reference coordinate system of the first user space. have.

As will be described later, the reference position and the reference coordinate system are based on the first user space creation time regardless of the second selection of the second user. It means the reference position and the reference coordinate system determined by In an embodiment, the reference position includes the position of the first user's client device at the time when the first user drives the virtual space forming program for the initial creation of the first user space.

In an embodiment, a vector value of the first position at the time of placement of the first selection object is calculated from the reference position, and a first position is obtained based on the vector value and the first position of the disposed first selection object. Based on the first spherical coordinate information (r, θ, ф) on the first spherical coordinate system, first reference coordinate information with respect to the reference coordinate system of the disposed first selection target may be calculated. That is, the arrangement information of the object arranged on various spherical coordinate systems having different origins may be converted into coordinate information about the reference coordinate system.

Also, in an embodiment, when the first user initially creates the first user space and then reconnects to the first user space by driving the virtual space forming program again, the first user space is the virtual space upon reconnection. The first user's location in ? may be the reference location regardless of the location in real space. For example, when the first user creates the first user space, which is the VR space, for the first time at position A in the real space, the position X in the first user space corresponding to the position A in the real space becomes the reference position. In addition, even if the first user reconnects to the first user space from the B position in the real space afterward, the first user remains at the X position in the first user space, which is the reference position in the virtual space, regardless of the B position in the real space. It is possible to reconnect to the first user space.

Contrary to this, in one embodiment, when the first user initially creates the first user space and then reconnects to the first user space by driving the virtual space forming program again, the first user who is the virtual space at the time of reconnection The first user's position in space may be a position in real space and a position calculated based on the reference position. For example, when the first user creates the first user space, which is the AR space, for the first time at the location A in the real space, the location X in the first user space corresponding to the location A in the real space becomes the reference location. In addition, when the first user reconnects to the first user space from the B position in the real space later, the first user may reconnect at the Y position in the first user space corresponding to the B position in the real space. That is, it is possible to determine the position in the first user space when the first user reconnects by calculating a vector value between the A position and the B position, and calculating the Y position of the first user space based on the vector value and the X position. have.

In another embodiment, the reference position 100 may be changed when storing the pre-generated first user space. That is, in one embodiment, the reference position of the first user space is the first user calculated from the arrangement position of the first user client device or the arrangement position of the first user client device at the time of storage whenever the first user space is stored. position, and the reference coordinate system may be changed accordingly.

In this case, when the first user reconnects to the stored first user space, the first user's location in the first user space, which is a virtual space, may be the changed reference location upon reconnection. For example, the first user creates the first user space, which is the VR space, for the first time at position A in the real space (corresponding to position X in the first user space), then moves to the first user space at position Z of the first user space. When the user space is stored, the Z position becomes the changed reference position of the first user space. In addition, when the first user reconnects to the first user space afterward, the first user may reconnect to the first user space at the Z position, which is the changed reference position in the virtual space, regardless of the location in the real space.

In addition, in this case, according to an embodiment, the first reference coordinates for the reference coordinate system before the change of the first selection object arranged according to the change of the reference position and the reference coordinate system are converted into the reference coordinates for the reference coordinate system after the change; may further include. For example, through the calculation of 'the vector value of the reference position before the change of the first selection object' and the 'vector value of the reference position before the change of the reference position after the change', the reference position after the change of the first selection object is calculated. By calculating the vector value, it is possible to calculate the reference coordinates for the reference coordinate system after the change of the first selection object.

Contrary to this, in one embodiment, the reference position and the reference coordinate system are not changed according to the storage of the first user space, but the first user client position at the time of storing the first user space is the position when the first user reconnects to the first user space can be
