Generally, an HMD device receives and projects an image from a device located outside the HMD device, and performs wired/wireless communication with an external device for this purpose. At this time, since the amount of data for realizing the virtual reality is generally large, the amount of data received by the HMD device is inevitably large.

Meanwhile, as the main purpose of the HMD device is to provide a user with a sense of virtual reality, when a user's movement is detected (for example, the user's head turns), an image reflecting the movement should be provided. That is, the HMD device should project an image corresponding to the user's movement as soon as it detects the user's movement, but in reality, as the image reflecting the movement is calculated by an external device, the HMD device takes a long time to receive and display the image. In addition, since the amount of data reflecting the change is generally large, a delay inevitably occurs between the time when the user's movement is generated and the time when the image reflecting the movement is projected.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a virtual reality display system 100 according to an embodiment of the present invention, and FIG. 2 shows an arithmetic device 10 included in the virtual reality display system 100 according to an embodiment of the present invention. 3 is a block diagram showing the wearing device 20 included in the virtual reality display system 100 according to an embodiment of the present invention.

As shown in FIG. 1 , a virtual reality display system 100 according to an embodiment of the present invention may include an arithmetic device 10 and a wearable device 20 .

The arithmetic device 10 and the wearable device 20 may perform wired/wireless communication. For example, the computing device 10 and the wearable device 20 may perform wireless communication with each other through a WiDi (Wireless Display) module included in each device. Additionally, the computing device 10 and the wearable device 20 may perform wired communication through a wired network and may also perform wireless communication through a wireless network.

On the other hand, the computing device 10, when the user gazes at the virtual reality information (for example, components constituting the three-dimensional virtual space) from the left and right eye viewpoints, respectively, the virtual The information may be rendered in a spherical shape and transmitted to the wearable device 20 so as to give a sense of reality to the reality information.

To this end, the arithmetic device 10 may include an information storage unit 110, a rendering unit 120, and an arithmetic and communication unit 130 as shown in FIG. 2 .

The information storage unit 110 according to an embodiment of the present invention may store virtual reality information. At this time, the stored virtual reality information is information about the image component before being rendered into an image, and thus, in order to display the virtual reality information in accordance with the wearing device 20, the rendering unit 120 needs to go through a rendering process.

Meanwhile, the rendering unit 120 may render virtual reality information.

That is, the rendering unit 120 may render virtual reality information in the shape of at least a portion of a sphere having both eyes of the user as a center point.

For example, the rendering unit 120 may render virtual reality information on a spherical surface in which each eye of the user is the central point while surrounding the user watching the rendered image.

Also, for example, the rendering unit 120 may render a central point of each eye of the user in a shape of a part of a sphere while surrounding the user watching the rendered image. To this end, the rendering unit 120 may render virtual reality information based on the user's viewing angle information and speed information. Here, 'viewing angle information' means the maximum angle that the user can see with the eyes, and may include, for example, information on the maximum left and right viewing angles or the maximum viewing angles up and down when the user is looking at the front. In addition, ‘speed information’ refers to the speed when the user facing the front moves his head.

In addition, the rendering unit 120 may re-render the virtual reality information based on the detection result when receiving a motion detection result generated by detecting that the user has moved the head from the wearable device 20 . .

For example, the rendering unit 120 based on the detection result, the front point of the user (a point when the user looks at the front in a comfortable state without turning the pupil), the user's viewing angle information, the calculation device 10, and wear Based on at least one of the time required for wired/wireless transmission and reception between the devices 20 and the maximum rotation angle per frame, when the virtual reality information is rendered on a spherical surface, an area that can be omitted from rendering, that is, an omitted area is determined, and the omitted area is determined. Areas other than the area can be re-rendered. If the rendering unit 120 does not determine the omitted area, the rendering unit 120 may re-render the virtual reality information as the entire sphere.

Meanwhile, the operation and communication unit 130 may perform wired and wireless communication with the wearable device 20 .

Accordingly, the operation and communication unit 130 may transmit the rendered image to the wearable device 20 and may receive a motion detection result of the user from the wearable device 20 .

In addition, the calculation and communication unit 130 may transmit the re-rendered image to the wearing device 20, and at this time, the calculation and communication unit 130 may transmit all of the re-rendered images to the wearing device 20, or Among the rendered images, only images that have not been transmitted to the wearing device 20 may be transmitted to the wearing device 20 .

The calculation device 10 including the information storage unit 110, the rendering unit 120, and the calculation and communication unit 130 according to the above description may be implemented as, for example, a computer equipped with a WiDi module, a portable terminal, or a television. can Here, the computer includes, for example, a notebook, a desktop, or a laptop, and the portable terminal is, for example, a wireless communication device that ensures portability and mobility, such as a smart phone.

Meanwhile, the wearing device 20 according to an embodiment of the present invention is a device that is worn on a user's head and receives and displays rendered virtual reality information from the computing device 10 .

As shown in FIG. 3 , such a wearable device 20 may include a wearable communication unit 210 , a motion sensor 220 and a display unit 230 .

The wearable communication unit 210 according to an embodiment of the present invention may perform wired/wireless communication with the arithmetic device 10 .

Accordingly, the wearable communication unit 210 may receive the rendered image from the arithmetic device 10, or may transmit the user's motion detection result obtained by the motion sensor 220 to the arithmetic device 10.

Meanwhile, the motion detection unit 220 may detect the movement of the user's head. As the wearable device 20 is worn on the user's head, the motion detection unit 220 may detect a movement angle, direction, speed, etc. of the user's head to generate a motion detection result.

To this end, the motion sensor 220 may be implemented with various sensors, for example, an accelerometer and a gyroscope sensor.

In addition, the motion detection unit 220 may transmit the user's motion detection result to the computing device 10 through the wearable communication unit 210 .

For example, when the movement range of the user's head is greater than or equal to a predetermined range, the motion sensor 220 determines that the angle at which the user's head has moved is greater than or equal to a predetermined range (eg, maximum rotation angle per frame). In this case, the motion detection result may be transmitted to the arithmetic device 10 .

Meanwhile, the display unit 230 may display an image received from the arithmetic device 10 .

At this time, the display unit 230 may display all of the received images, but may select and display an image within the user's viewing angle range based on the user's viewing angle information. In addition, when the display unit 230 detects the user's motion according to the user's motion detection result obtained by the motion sensor 220, the rendered image that is not being displayed among the previously received and stored rendered images is displayed according to the movement. It can be displayed based on the changed front point.

In this way, the wearing device 20 including the wearable communication unit 210, the motion detection unit 220, and the display unit 230 is implemented to include a body or frame similar to glasses that can be placed on the user's nose and ears, or It can be implemented to include a helmet-like body or frame that can enclose the user's head. In addition, the wearing device 20 may display an image to be displayed by the display unit 230 through a display device positioned in front of both eyes of the user.

Meanwhile, FIG. 4 is a flowchart illustrating a virtual reality display method according to an embodiment of the present invention.

The virtual reality display method according to the embodiment shown in FIG. 4 includes steps processed time-sequentially in the virtual reality display system 100 shown in FIGS. 1 to 3 . Therefore, even if the contents are omitted below, the contents described above with respect to the virtual reality display system 100 shown in FIGS. 1 to 3 can also be applied to the virtual reality display method according to the embodiment shown in FIG. 4 .

When the virtual reality display system 100 intends to provide virtual reality information to the user, as shown in FIG. 4 , the computing device 10 may render the virtual reality information to be displayed through the wearable device 20. Yes (S400). At this time, the computing device 10 may render the virtual reality information in the shape of at least a part of a sphere having both eyes of the user as a central point.

In relation to FIGS. 5 and 6, each is an exemplary view for explaining a virtual reality display method according to an embodiment of the present invention, and each of the eyes of the user U wearing the wearable device 20 on the head is the center point. It is to explain how to render virtual reality information in the shape of at least a part of a sphere to be. At this time, the spherical surface of FIGS. 5 and 6 is expressed as a two-dimensional circle for convenience of description.

That is, as shown in FIG. 5 , the arithmetic device 10 surrounds the user U wearing the wearable device 20 on the head and has a spherical surface 510 with the left eye of the user U as the center point. ) to render virtual reality information. Also, the computing device 10 may render the virtual reality information as a sphere 520 surrounding the user U and having the right eye of the user U as a central point. That is, the arithmetic device 10 may render the virtual reality information as a spherical surface with both eyes of the user U as the central point.

On the other hand, in view of the fact that the field of view that the user U can see at one time is determined, as shown in FIG. 6, the arithmetic device 10 displays the area to be displayed according to the viewing angles 612 and 622 of the user U. (511, 521) and some areas of the spherical surface including areas 611 and 621 that may be displayed according to the head movement speed V of the user U in case the user U moves the head ( 610 and 620), virtual reality information may be rendered. That is, for example, assuming that the viewing angles 612 and 622 of the user U are 170 degrees and the user U can turn his/her head at a speed V of 20 degrees in 1/60 second, the arithmetic device ( 10) may render an image in a partial shape of a sphere corresponding to a range of 210 degrees (= 170 + (20 * 2)). By rendering the virtual reality information to a partial area of the sphere in this way, the processing unit 10 can minimize the time and resources required to generate the rendered image, and minimize the amount of data of the rendered image to perform encoding for transmission and reception of the rendered image. / It is possible to minimize the time required for decoding and also to minimize the amount of data transmitted and received.

When the computing device 10 completes rendering of the virtual reality information, it may provide the rendered image to the wearing device 20 (S410).

And, the wearing device 20 may store and display the received rendered image (S420). At this time, the wearing device 20 may display all of the received rendered images or may display some of the received rendered images based on the viewing angle information of the user U.

In this regard, as shown in FIG. 5 , the wearing device 20 that has received an image rendered as the entire sphere may display only images of portions 511 and 512 of the spheres 510 and 520 . Also, as shown in FIG. 6 , the wearing device 20 that has received the rendering image as a part of the sphere may display only the images of the parts 511 and 512 of the parts 610 and 620 of the sphere.

Then, when the wearing device 20 detects the user's movement (S430), it can display a rendering image that is not displayed among the previously received and stored rendering images based on the front point changed according to the user's movement (S440). . For example, referring to FIG. 6 , when a movement of the user U in the right direction is sensed, the wearing device 20 does not display images 511 and 521 other than the previously received and stored rendered images 511 and 521 . A rendered image of the unpainted area 621 may be displayed. Through this, the feedback speed for the user's motion can be increased, so that the user can enjoy virtual reality without feeling motion sickness without feeling incongruity between the user's motion and the rendered image.

Meanwhile, when the wearer 20 detects the user's movement, when the movement angle of the user's head is greater than or equal to the maximum rotation angle per frame (S450), the wearer 20 transmits the motion detection result to the calculator 10. It can be transmitted as (S460).

When the calculation device 10 receives the detection result, the user's front point changed according to the movement, the user's viewing angle information, the time required for wired/wireless transmission and reception between the calculation device 10 and the wearable device 20, and the maximum per frame Virtual reality information may be re-rendered based on at least one of the rotation angles (S470).

Specifically, the arithmetic device 10 may determine whether an omitted area exists according to the following <Equation 1>.

<Equation 1>

Θv + 2(t(c)+t(m)+1)*Θr

Here, Θv is the viewing angle, and Θr is the rotation angle per frame. In addition, t(c) is the time required for the wearable device 20 to request rendering while transmitting the motion detection result to the computing device 10, and t(m) is the time required for the computing device 10 to perform the rendering according to the request. As the time required to perform rendering and transmit the re-rendered image to the wearable device 20, each unit of t(c) and t(m) is a frame. Each of t(c) and t(m) may be different for each computing device and wearable device, and thus, while performing communication between the computing device and the wearable device before the virtual reality display system displays virtual reality information, t(c) and t(m) values can be obtained.

For example, if the user's viewing angle Θv is 210 degrees, 5 rotations per second are possible, and virtual reality information has 30 frames per second, so the rotation angle Θr per frame is 60 degrees, t(c) and t(m) If each frame is 0.5, it can be seen that the omitted area does not exist because the value according to Equation 1 is 450 degrees greater than 360 degrees. On the other hand, when the user's viewing angle Θv is 210 degrees, 5 rotations per second are possible, and the virtual reality information has 30 frames per second, the rotation angle Θr per frame is 60 degrees, and t(c) and t(m) are respectively If it is 0.05 frame, the value according to Equation 1 is 342 degrees smaller than 360 degrees, so it can be seen that there is an omitted area.

If the calculation device 10 determines that the omitted area does not exist according to <Equation 1> as described above, the virtual reality information may be re-rendered as the entire sphere based on the front point of the user.

On the other hand, if the calculation device 10 determines that an omitted area exists according to <Equation 1>, the virtual reality information is re-rendered as a sphere based on the front point of the user, but only the remaining areas excluding the omitted area are re-rendered. can

In relation to this, FIG. 7 is an exemplary view for explaining a virtual reality display method according to an embodiment of the present invention, at least of a spherical surface having the right eye of the user U wearing the wearable device 20 on the head as the center point. This is to explain how virtual reality information is rendered in a partial shape. At this time, the spherical surface of FIG. 7 is expressed as a two-dimensional circle for convenience of explanation.

As shown in FIG. 7, left and right ((360-(Θv+2(t(c)+t(m)+1)*Θr))/ Virtual reality information may be rendered to the remaining area 720 except for the omitted area 730 in which the spherical rendering is omitted by the angles 730 and 740 of 2.

When the computing device 10 re-renders the virtual reality information as described above, the re-rendered image may be provided to the wearable device (S480).

Each of the above steps may be continuously repeated until the virtual reality display system 100 determines to end the display (S490).

For example, the virtual reality display system 100 may determine the end of the display when the user requests termination of the display of virtual reality information, or, for example, when the user's position changes (eg, the user wears If you walk or run while wearing the device) and then a rendered image is required based on the virtual reality information to be newly provided, the virtual reality display system 100 determines the end of the display, and You can restart the flow chart according to the reality display method.
