1 is a block diagram illustrating the configuration of a VR content providing system according to the present invention. 2 is a flowchart illustrating a VR content providing method according to the present invention. 3 to 9 are reference views for explaining a VR content providing method according to the present invention.

The VR content providing system 100 according to the present invention may operate in conjunction with an electronic device capable of outputting (or playing back) VR content. As shown in FIG. 1 , the VR content providing system 100 according to the present invention may operate in conjunction with the head mounted display 200 . The VR content providing system 100 according to the present invention may include at least one of an input unit 110 , an output unit 120 , and a control unit 130 . Here, the controller 130 may control overall components of the VR content providing system 100 according to the present invention.

The VR content providing system 100 according to the present invention is not limited to the above-described components, and may further include components that perform the same role as the device described herein.

First, a head mounted display (200, Head mounted display, hereinafter referred to as 'HMD') is a generic term for image display devices that can be worn like glasses to enjoy images, and is recently also called FMD (Face Mounted Display). The HMD serves to show the virtual world to the user's eyes after blocking the user's sight and hearing from the outside. As an example, the HMD has a microphone, a stereo speaker, and various sensors mounted on it in a form that is worn on the face so that the display is in front of the eyes.

The HMD may provide a virtual space through the view area. In the following specification, a view area corresponding to a user's gaze among a plurality of view areas (or display areas) provided by the HMD will be referred to as a “main view area” 210 .

In particular, such an HMD may display VR (Virtual Reality) content. Furthermore, the HMD may display either augmented reality (AR) content or mixed reality (MR) content.

Here, the content refers to data, data, or information of signs, characters, figures, colors, voices, sounds, images, and images (or a complex of at least two of them).

VR content is content that gives an immersive feeling as if a user actually experiences an image viewed by a user, and may be produced using a three-dimensional or two-dimensional image. On the other hand, AR content may be produced to provide users with a mixture of 3D or 2D images in a real environment. Meanwhile, MR content. By mixing AR and VR, it can be produced to provide users with real and virtual information in a real background.

Meanwhile, the output unit 120 may output the VR content to a view area (eg, a main view area) of the HMD 200 linked with the VR content providing system 100 according to the present invention.

In the present invention, VR content is content that gives an immersive feeling as if the user actually experiences an image viewed by the user, and may include, for example, content related to learning.

Meanwhile, in the present invention, the controller 130 may output a reference image together with the VR content, where the reference image is an image located in at least one area on the main view area of the HMD 200 and has various shapes. can have

In the present invention, the final reference image output on the main view area may be any one image selected from among a plurality of candidate reference images. In this specification, the reference image is a generic term for a plurality of candidate reference images and a specific reference image, and may be used interchangeably.

Such a reference image may be output on a specific position regardless of the output state (or playback state) of the VR content on the main view area of the HMD 200 . For example, the reference image is located on specific coordinates corresponding to at least one area of the main view area even when VR content with motion is displayed (ie, even when VR content consisting of a moving picture is being played). can do.

Here, the position (or fixed position) at which the reference image is output may correspond to output coordinates previously matched to the reference image. The output coordinates pre-matched to the reference image may exist in a memory as pre-stored data.

Meanwhile, the output timing of the reference image may be set in various ways, and as an example, the reference image may be output at the same time as the VR content is output by the setting of the controller (or system). For example, when VR content is output, a specific reference image according to a basic setting may be output to an output coordinate area matched to the specific reference image.

Such a reference image may disappear from the main view area based on a user's request or under the control of the controller 130 . That is, in this case, the reference image is not output on the main view area.

Meanwhile, the reference image whose output has been completed may be output again on the main view area under the user's request or the control of the controller 130 again.

As another example, the reference image may be output to one area of the main view area only when there is a user's request.

Meanwhile, the VR content providing system 100 according to the present invention provides a reference image (or a specific reference image) to a specific area on the main view area while the VR content is being output (or being reproduced) on the main view area. can be printed out.

The present invention provides a VR content providing system and a VR content providing method capable of maximizing the three-dimensional effect of VR content and alleviating motion sickness symptoms by using the above-described reference image.

First, VR content is output on the main view area of the head mounted display ( S210 ).

Here, the VR content may be formed of a depth image. In the present specification, a depth image refers to an image in which the depth of an image is divided into several ranges, a region of a 2D image is divided according to a depth range, and then layered according to a depth order of the divided regions. There are various methods for generating the depth image, and the present invention generates the depth image in a known manner or obtains and utilizes a previously generated depth image.

The depth image includes a plurality of regions. In the present specification, one region of the depth image is defined as a portion of the depth image to which the same depth value is matched. A depth value is matched to each of the plurality of regions.

The controller 130 projects and outputs the depth image on the 3D virtual space by using the depth value matched to the depth image. Specifically, the controller 130 divides the depth image into a plurality of objects according to the matched depth value, and projects each of the divided objects in the 3D virtual space according to the depth order. In this case, the controller 130 may scale and output the positional relationship and size between the objects by using the depth value. For example, as the depth value matched to the object increases, the size of the object may decrease during the scaling process. On the other hand, as the depth value matched to the object increases, the size of the object may increase during the scaling process. Meanwhile, various well-known methods may be applied in the process of scaling an image based on a depth value. In the present specification, 'projecting and outputting an image (VR content) on a three-dimensional virtual space' and 'outputting an image (VR content) according to a matched depth value' are based on the depth value matched to the depth image. This means that the objects included in the depth image are scaled and then output.

When the depth image is applied to a moving picture, each of a plurality of frames constituting the moving image may be formed of a depth image. Each of the plurality of depth images constituting the moving image includes different areas and different numbers of regions. When a plurality of depth images are output at a constant time interval (frame time), the sense of depth at a specific point in the main view area may not change or may change with time. For example, assume VR content in which a human-shaped object walks from the left to the right of an image, but the human-shaped object gradually moves away from the viewer. When gazing at the left area of the main view area, the sense of depth of the left area is different from the time point at which the human figure is outputted and the time point at which the background is outputted. When the same background is output to the left area, the depth of the left area remains the same.

As described above, when a plurality of depth images are output at regular time intervals, a sense of depth at a specific point in the main view area depends on a depth value set in the plurality of depth images to be output. In the present specification, for convenience of description, when describing a sense of depth at a specific point in the main view area, a depth value matched with a portion of a depth image being output to a specific point in the main view area will be described. Specifically, that the depth value matched to a specific point in the main view area increases over time means that the depth value matched to a portion of the depth image output at a predetermined time interval at the specific point sequentially increases. do. That is, the depth value is a set value matching each of the regions constituting the depth image, but in the present specification, such an expression is omitted and the depth value is expressed in association with a specific point of the main view region.

For example, when a spherical object output to the center describes VR content that moves toward the viewer as time passes, in this specification, it is expressed that the depth value matched to the center of the main view area decreases with time.

While the VR content including the depth image is being output, the step of outputting a graphic object to the border area of the main view area ( S220 ) is performed.

The graphic object has a predetermined thickness and has a shape extending along the edge of the main view area.

In an embodiment, the graphic object may be formed in the shape of a frame of glasses. More specifically, the graphic object may be formed in the shape of the rim of the glasses viewed by the wearer of the glasses.

In the field of view of the wearer of the spectacles, the rim of the spectacles is positioned at the rim of the wearer's field of view. The graphic object may be disposed on the edge of the main view area to give the user a feeling of wearing glasses.

Meanwhile, the graphic object may be output in different types of glasses shapes. Specifically, the graphic object may have various shapes, such as eyeglasses for vision correction, sunglasses, and goggles. The shape of the glasses depicted by the graphic object is not specifically limited.

On the other hand, there may be a plurality of graphic objects, each of the plurality of graphic objects does not necessarily need to be connected, and it is sufficient that the shape and arrangement of the plurality of graphic objects are recognized as the rim of the glasses.

As the graphic object is output while VR content is being output, the main view area may be divided based on the graphic object. Specifically, the main view area may include a first area surrounded by the graphic object and a second area located opposite to the first area with respect to the graphic object. VR content may be output to both the first and second regions.

The VR content may be output while being partially covered by the graphic object. In this case, a part of the VR content is output to the first area, and the remaining part is output to the second area.

Meanwhile, a position at which the graphic object is output may be changed according to a user request. Specifically, the controller 130 may make the graphic object move closer to or away from the end of the main view area according to a user's request.

When the graphic object approaches the end of the main view area while maintaining its thickness, the area of the first area increases and the area of the second area decreases. In this case, the user may receive a feeling of wearing glasses that are already worn by replacing them with larger glasses. On the other hand, when the graphic object moves away from the end of the main view area while maintaining its thickness, the area of the first area decreases and the area of the second area increases. In this case, the user may receive a feeling of wearing the glasses that are already worn by replacing them with smaller glasses. As described above, the size of the graphic object may be freely changed according to a user's request.

The graphic object is output while overlapping the VR content while the VR content consisting of a moving picture is being output. The controller 130 statically outputs the graphic object even if the VR content output to the main view area changes ( S230 ).

When video VR content is output, screen information output to the main view area changes with time. In this case, the graphic object is continuously output at the same position in the main view area. Accordingly, screen information overlapping with the graphic object may vary according to time.

The graphic object may be output translucently so that the user can check screen information overlapped with the graphic object, but is not limited thereto.

Referring to FIG. 3 , VR content is output to the main view area 310 , and a graphic object 320 is output to the edge of the main view area 310 . A part of the screen information output to the main view area overlaps the graphic object 320 . Since the graphic object 320 is output translucently, the user can check screen information overlapped with the graphic object 320 .

Since the graphic object is continuously output to the same position even if the screen information output to the main view area changes, it serves as the above-described reference image. That is, the graphic object serves to reduce motion sickness caused when viewing VR content.

Meanwhile, the graphic object may be output while the VR content including the above-described depth image is being output. When VR content including the depth image is output, depth values matched to respective regions constituting the main view image may be different, and a depth value matched to one region of the main view image may vary over time. .

A depth value matching a region of the main view image to which the graphic object is output is always maintained the same while VR content is output. In an embodiment, a depth value matching a region of the main view image to which the graphic object is output may be always maintained as a minimum value. Through this, the present invention can give the user a feeling of watching VR content while wearing glasses.

The VR content includes a plurality of objects matched with different depth values. The controller 130 projects and outputs the plurality of objects in a 3D virtual space according to the matched depth value. An output area of each of the plurality of objects on the main view area may vary with time, and a new object matching a specific depth value may be output on the main view area. In this case, the depth value matched to a specific point on the main view area may continuously change while the VR content is being output.

Here, the graphic object is output according to a specific depth value, and overlaps with the VR content. The specific depth value matched to the graphic object does not change even if screen information output to the main view area changes. Specifically, while the VR content and the graphic object overlap and output, even if a depth value matched to an overlapping region of the graphic object in the VR content changes, the graphic object is output according to the specific depth value. That is, an area in which the graphic object is output among the main view areas is always output with the same depth value.

In one embodiment, referring to FIG. 4 , screen information output to the main view area 410 may change while VR content and a graphic object 420 for motion sickness reduction are output on the main view area 410 . have. Even if the screen information output to the main view area 410 changes, the output position of the graphic object 420 does not change. Specifically, as the screen information output to the one region 410a of the main view region changes, even if the depth value matched to the one region 410a changes, the graphic object ( 420) does not change the depth value of the part.

In another embodiment, referring to FIG. 5 , the main view area 510 includes a plurality of areas 510a and 510b. The output position of the object being output to the second area 510b may be changed to the first area 510a, and a depth value matching the object may increase. Accordingly, the object may appear to be located further away. Even if the output position of the object is changed, the depth value of a portion of the graphic object 520 output to the plurality of regions 510a and 510b does not change.

As described above, according to the present invention, a graphic object for motion sickness reduction is output at the same location according to the same depth value while VR content including a depth image is output. Through this, the present invention prevents the user from feeling motion sickness and at the same time makes the graphic object for motion sickness reduction always look at the same distance, so that the user does not feel a sense of heterogeneity with the graphic object for motion motion sickness reduction.

Meanwhile, according to the present invention, another auxiliary graphic object capable of reducing motion sickness of a user and maximizing a three-dimensional effect of an image may be output.

Specifically, the method may further include outputting a nose-shaped auxiliary graphic object to the edge of the main view area.

The nose-shaped auxiliary graphic object is output to the lower center of the main view area so as to give the same feeling as the user's nose. The nose-shaped auxiliary graphic object is output with the same depth value as the graphic object, and even if screen information output to the main view area is changed, a depth value matching the nose-shaped auxiliary graphic object does not change. Specifically, the nose-shaped auxiliary graphic object is output to overlap a part of the VR content. Even if the depth value matched to the screen information overlapping with the auxiliary graphic object of the nose shape changes, the depth value of the region where the auxiliary graphic object of the nose shape is output does not change. Through this, the present invention provides a field of view identical to the field of view when the user wears glasses.

In one embodiment, referring to FIG. 6 , a graphic object 620 in the shape of a glasses rim and an auxiliary graphic object 630 in the shape of a nose are output together in the main view area 610 .

The nose-shaped auxiliary graphic object 630 is output to the lower central portion of the main view area 610 , and is output to overlap the graphic object 620 . Even if the screen information displayed on the main view area changes, the output position of the nose-shaped auxiliary graphic object 630 does not change.

Meanwhile, the present invention outputs an auxiliary graphic object in the shape of a mouth during VR content output. Specifically, the controller 130 may output voice data included in the VR content.

The voice data may be associated with a specific object among a plurality of objects included in the VR content. Here, being associated with a specific object among a plurality of objects included in the VR content means when the specific object performs a specific action within the VR content to give the feeling that the voice data is output from the specific object. , means that the voice data is output together.

The VR content may include a plurality of voice data, and each voice data may be stored to match at least one of a plurality of objects included in the VR content.

When the voice data is output, the controller 130 searches for an object related to the voice data from among a plurality of objects included in the VR content. The controller 130 searches for an object stored by matching the voice data being output.

Thereafter, the controller 130 overlaps the mouth-shaped auxiliary graphic object with the searched object and outputs it. In this case, the control unit 130 causes the auxiliary graphic object of the mouth shape to move with a movement corresponding to the voice data. Specifically, the controller 130 may cause the auxiliary graphic object of the mouth shape to move in the shape of a mouth necessary to utter a sound corresponding to the voice data.

In one embodiment, referring to FIG. 7 , while VR content and graphic object 720 are output on the main view area 710 , voice data 730 may be output. The voice data 730 may be voice data associated with a specific object included in VR content.

When the voice data is output, an auxiliary graphic object 740 in the shape of a mouth is output to overlap a specific object related to the voice data. The auxiliary graphic object 740 in the shape of a mouth can be moved in the shape of a mouth necessary for voicing the voice corresponding to the voice data so as to give a feeling as if the voice data is output from the auxiliary graphic object 740. .

On the other hand, the present invention minimizes the number of icons output to the main view area so that the user's viewing of VR contents is not disturbed. To this end, the present invention utilizes the graphic object described with reference to FIGS. 2 to 7 .

The HMD according to the present invention may perform various functions in response to a user request. The above functions may be performed when the user applies a user input to the icon output on the main view area.

If the icons are continuously output while the VR content is being output, it may interfere with the user's viewing of the VR content. According to the present invention, the icons may not be displayed during VR content output unless there is a separate user request so that the icons do not interfere with the user's viewing of VR content.

The present invention utilizes the graphic object so that the above-described icons can be output when a user desires. Specifically, the controller 130 receives a user input in the region where the graphic object is output, and in response to the user input for the graphic object, displays at least one icon related to a function executable on the head mounted display. Overlap with VR content and output.

When a user input is applied to the icon while the at least one icon is output, the controller 130 may execute a function corresponding to the icon to which the user input is applied.

When a user input is not applied to the at least one icon for a preset time, the controller 130 causes the at least one icon to disappear from the main view area.

In an embodiment, referring to FIG. 8 , when a user input is applied to one area 830 of the graphic object 820 output to the main view area 810 , the VR content image is displayed in the main view area 810 . A plurality of icons 840 related to control are output.

Here, a user input to the graphic object 820 may be made through the input unit 110 . In an embodiment, when the user applies a touch to the input unit 110 , a graphic object (eg, a cursor) for user input is output on the main view area. The controller 130 detects a user's touch input to the input unit 110 and moves the cursor on the main view area. The user can apply a user input to a desired position on a desired main view area by moving the cursor.

The user can control the VR content through a user input to the plurality of icons 840 .

Meanwhile, the controller 130 may execute different functions according to a location to which a user input is applied among the entire area of the graphic object. Specifically, when the main view area is formed of a rectangle, the graphic object according to the present invention is output to be adjacent to each of the four corners included in the main view area.

The controller 130 may cause different functions to be executed according to an edge adjacent to a position to which a user input is applied among the entire area of the graphic object.

In an embodiment, when a user input is applied to an area adjacent to the upper edge of the main view area among the entire area of the graphic object, the controller 130 may output an icon related to the reproduction of the VR content. Contrary to this, when a user input is applied to one area adjacent to the lower edge of the main view area among the entire area of the graphic object, the control unit 130 may output an icon related to brightness and volume control of an image.

For example, referring back to FIG. 8 , when a user input is applied to one area 830 adjacent to the upper edge of the main view area among the entire area of the graphic object 820, an icon related to the reproduction of VR content is displayed. output 840 .

On the contrary, referring to FIG. 9 , when a user input is applied to one area 930 adjacent to the left edge of the main view area among the entire area of the graphic object 920a, the graphic object is transformed into a different shape 920b. is changed

As described above, the present invention enables natural VR content viewing by executing a function executable in the HMD through a graphic object output for motion sickness reduction without outputting a separate icon during VR content output.

As mentioned above, although embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can realize that the present invention can be embodied in other specific forms without changing its technical spirit or essential features. you will be able to understand Therefore, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
