Description

Augmented reality content output device

The present invention relates to an augmented reality content output device, and more specifically, to an augmented reality content output device that can add a sense of space to provided augmented reality content.

Virtual Reality (VR) refers to a human-computer interface that creates a specific environment or situation with a computer, making it as if the person using it is interacting with the actual surrounding situation or environment.

Augmented Reality (AR) is a technology that superimposes virtual objects on the real world that the user sees. It is also called mixed reality (MR) because it combines the real world with a virtual world with additional information in real time and displays it as a single image.

Although a variety of augmented reality content is provided, augmented reality content is usually created by including a character corresponding to the user or a user's appearance input in real time as an object in the basic background of the augmented reality content.

In other words, it is possible to control the movement of the object corresponding to the user within the augmented reality content according to the user's appearance information input in real time, but depending on the movement of the object corresponding to the user, the angle of view of the background of the augmented reality content or the angle of view of the background of the augmented reality content is possible. Since the angle of view of objects included in the content does not appear to change, there is a problem in that the provided augmented reality content has a low level of homogeneity.

In addition, even if augmented reality content is provided by increasing the sense of homogeneity, it is provided through the display means with the sense of heterogeneity maximized, so the problem is that users' participation is lowered due to low empathy and low homogeneity. There is.

In order to overcome this problem, the augmented reality content output device uses a separate connection means on the front part of the display means so that the user cannot directly perceive the entire display means, thereby adding to the sense of space of the augmented reality content. , By receiving the user's key information and controlling the view point of the augmented reality content shown to the user, the sense of homogeneity of the augmented reality content can be improved.

The present invention was created to solve the problems of the prior art as described above. The purpose of the present invention is to provide an augmented reality content output device that can add a sense of space to augmented reality content provided through a display means.

An augmented reality content output device according to an embodiment of the present invention is a connection medium for an augmented reality content provision service, receives an input signal from a user who desires an augmented reality content provision service, and sends the input signal to a network connected device. It is preferable to include a connection means for transmitting to the content control means and a display means installed behind the connection means to output the augmented reality content transmitted from the content control means connected to the network.

Furthermore, the augmented reality content output device is connected to a network with the connection means and the display means, uses user-related information input together with the input signal of the connection means, and pre-stores augmented reality content according to the information. It is desirable to further include a content control means for controlling and transmitting the content to the display means.

Furthermore, the connection means is in the shape of a swing door and includes a plurality of frames, a door frame in which at least one camera and microphone are provided in one selected frame, and one end of the door frame is coupled to one side of the inner surface of the door frame to enable opening and closing. It is preferable to include a second door panel, the other end of which is coupled to the other inner surface of the first door panel and the door frame, so that it cannot be opened or closed.

Furthermore, the first door leaf and the second door leaf have the same height in the y-axis direction with respect to the door frame, and have different lengths in the x-axis direction with respect to the door frame, and the It is preferable that the length is longer than the length of the second door in the x-axis direction.

Furthermore, the door frame is provided with at least one sensor in one selected frame, and the sensor detects the opening of the first door, and when the opening of the first door is detected, the content control means detects the opening of the first door. It is preferable that a signal is transmitted, and when the detection signal is received, the content control means transmits the augmented reality content to the display means.

Furthermore, the display means is preferably installed at the rear of the connection means and spaced apart from the connection means using a predetermined ratio according to the screen size on which the augmented reality content is displayed.

Furthermore, the sensor acquires the user's key information located at the front of the access means and transmits it to the content control means, and the content control means reflects the received user's key information, and the access means It is desirable to set the main camera for photographing the user among the cameras provided in or to control the installation height of the camera for photographing the user.

Furthermore, the connection means is provided with an input means in the form of a button located on a front side and receives an input signal operated by the user, and transmits the input signal of the input means to the content control means. Preferably, the content control means transmits augmented reality content corresponding to the input signal among pre-stored augmented reality content to the display means.

The augmented reality content output device of the present invention with the above configuration configures an obstacle of arbitrary shape (door shape or window shape) in front of the display means through which augmented reality content is output, so that users who want augmented reality content provision service A device can be provided to maximize the sense of space.

In other words, even if the sense of reality/immersion of the augmented reality content itself is improved, there are bound to be limitations to the content provided through display means such as monitors. In order to resolve this, an arbitrary shape (door shape or window) is placed in front of the display means. There is an advantage of adding a sense of space by locating the connection means of the shape and receiving content output from the display means located beyond the door.

In addition, it provides already created augmented reality content, breaking away from the conventional augmented reality content provision service that simply provides already created augmented reality content or provides content by adding users in the form of objects in augmented reality in real time. Even if the viewing angle of the augmented reality content is corrected according to the user's view point, or the content is provided in the form of an object within the augmented reality/virtual reality content through the so-called 'metaverse', the user is provided with the augmented reality content in real time. Even when added in the form of a predetermined object, there is an advantage in improving the sense of immersion in the provided augmented reality content by reflecting the user's key information and correcting the viewing angle of the content.

Figure 3 is an exemplary diagram showing an augmented reality content providing service using an augmented reality content output device according to an embodiment of the present invention.

Figures 4 and 5 are exemplary diagrams showing augmented reality content in which the height of the user's viewpoint is controlled provided by an augmented reality content output device according to an embodiment of the present invention.

Hereinafter, the augmented reality content output device of the present invention will be described in detail with reference to the attached drawings. The drawings introduced below are provided as examples so that the idea of the present invention can be sufficiently conveyed to those skilled in the art. Accordingly, the present invention is not limited to the drawings presented below and may be embodied in other forms. Additionally, like reference numerals refer to like elements throughout the specification.

At this time, if there is no other definition in the technical and scientific terms used, they have the meaning commonly understood by those skilled in the art to which this invention pertains, and the gist of the present invention is summarized in the following description and attached drawings. Descriptions of known functions and configurations that may be unnecessarily obscure are omitted.

The augmented reality content output device according to an embodiment of the present invention arbitrarily configures an obstacle of an arbitrary shape (door shape or window shape) in front of the display means through which augmented reality content is output, thereby providing a desired augmented reality content provision service. This relates to a device for maximizing the user's sense of space.

It is desirable to use this in an interactive augmented reality content creation system to provide augmented reality content services in places where outdoor activities are decreasing due to the long-term spread of the COVID-19 pandemic and demand for non-face-to-face services is needed.

In addition, the augmented reality content output device according to an embodiment of the present invention simply provides already created augmented reality content through a content control means, or adds the user in the form of a predetermined object in augmented reality in real time to provide content. Going further than the conventional augmented reality content provision service, even if already created augmented reality content is provided, the viewing angle of the augmented reality content is corrected according to the user's viewpoint, or through the so-called 'metaverse'. Even if the content is provided in the form of an object within the augmented reality/virtual reality content, the viewing angle of the content can be corrected and provided by reflecting the user's key information even when the user is added in real time as a predetermined object within the augmented reality content.

Through this, it is possible to maximize the sense of immersion and sense of space in the provided augmented reality content.

Figure 1 is an exemplary configuration diagram showing an augmented reality content output device according to an embodiment of the present invention. The augmented reality content output device according to an embodiment of the present invention will be described in detail with reference to Figure 1.

As shown in FIG. 1, the augmented reality content output device according to an embodiment of the present invention includes a connection means 100 and a display means 200. The connection means 100 and the display means 200 ) and a content control means 300 each connected to a wired or wireless network. It is preferable that the various components included in the content control means 300, the access means 100, and the display means 200 are individually or collectively included in at least one computational processing means including a computer to perform operations. .

To learn more about each configuration,

The connection means 100 is a connection medium for the augmented reality content provision service. It receives an input signal from a user who wants the augmented reality content provision service, and transmits the input signal to the content control means 300 connected to the network. It is advisable to send it. As shown in FIGS. 1 and 3, the connection means 100 preferably receives the input signal from a user located at the front at a certain distance, and serves as a connection medium for the augmented reality content providing service. To perform this, as shown in FIG. 3, at least two connection means 100 located at a distance may be connected to a network to receive an augmented reality content provision service.

In this case, the video call function can be performed between family members or friends who are far away from each other through the augmented reality content provision service even from a distance through the connection means 100, or the augmented reality video call function can be performed at a tourist destination that cannot be visited in person in the era of the pandemic. When the connection means 100 by the content output device is located, a long-distance travel function can be performed through the augmented reality content provision service even if one does not go directly to the tourist destination.

For this purpose, it is preferable that the display means 200 is installed behind the connection means 100.

In detail, the display means 200 receives augmented reality content from the content control means 300 and outputs it, and for this purpose, it is preferably provided in the form of a display panel.

In addition, the display means 200 are provided in a matching manner for each connection means 100, and as shown in FIG. 1, they are installed at a predetermined distance apart from the rear (rear portion) of the connection means 100. desirable. At this time, the separation distance between the connection means 100 and the display means 200 is preferably set using a preset ratio according to the screen size of the display means 200 on which the augmented reality content is output.

As described above, since the connection means 100 is located between the display means 200 and the user, it is an augmented reality content providing service that provides other users or different environments beyond the connection means 100. It is desirable to set the optimal separation distance to improve the fun, immersion, realism, and sense of space in providing real content, and the display means (200) beyond the connection means (100) based on the position where the user is standing. ) It is most desirable to have a distance where the edge (border) of the display panel is not visible. At this time, it is desirable that the user's standing position be set in advance, taking into account the camera view angle, the sensor's sensing range, etc., just as when receiving an experience video through a display panel.

The content control means 300 is connected to the connection means 100 and the display means 200 by a wired or wireless network, and uses user-related information input together with the input signal of the connection means 100, It is desirable to control the augmented reality content that has been stored in advance according to the information and transmit it to the display means 200.

Here, the connection means 100 is preferably configured to include various sensing means in order to transmit the user-related information to the content control means 300.

In detail, as described above, the connection means 100 preferably has a predetermined/arbitrary shape (door shape or window shape) that serves as a connection medium for the augmented reality content providing service, and is shown in FIGS. 1 to 1 3, the shape of the connection means 100 having the shape of a door is shown, but this is only an embodiment of the present invention, and if it can serve as a connection medium for the augmented reality content providing service, The shape is not limited.

Hereinafter, for clear explanation, the 'door-shaped' connection means 100 shown in FIGS. 1 to 3 will be described as an example, and is only an example.

An example of the shape of the connection means 100 is a ‘door’, which is in the shape of a swing door and is composed of a door frame, a first door, and a second door.

The door frame is preferably configured to include a plurality of frames to support the door shape, and at least one camera and microphone are provided in one selected frame.

Through the camera, a user who wishes to receive an augmented reality content provision service is captured, and the user's voice signal is acquired through the microphone. Additionally, in the case of a camera or microphone, since sensing information may differ depending on the installation location, it is most desirable to install the camera and microphone on a fixed and immovable door frame.

Preferably, the first door leaf is formed so as to be open and closed by being coupled at one end to one side of the inner surface of the door frame, and the other end of the second door leaf is coupled to the other inner surface of the door frame so as to be impossible to open and close. Through this, when a user who wants an augmented reality content provision service wants to access the augmented reality content provision service and performs an operation of opening the first door, this is input as a trigger signal (detection signal) and the detection signal is sent to the above. It is transmitted to the content control means 300 so that the augmented reality content is output through the display means 200.

Here, to explain the 'window' as an example of the shape of the connection means 100, it is composed of a door frame, a first window, and a second window, and one selected window is installed to be open and closed, and the other window is opened and closed. It is fixedly installed so that it is impossible. In addition, similar to the shape of the door, a trigger signal is input through the operation of opening a window that can be opened and closed.

In detail, it is preferable that the door frame is further equipped with a sensor that detects whether the first door is opened in addition to the camera and microphone.

Through this, for example, when a user who wants an augmented reality content provision service opens the first door to access the augmented reality content provision service, the sensor detects the opening of the first door, and the content A detection signal is transmitted to the control means 300. When the detection signal is received, the content control means 300 transmits the pre-stored augmented reality content to the display means 200 and outputs it through the display means 200. At this time, the augmented reality content transmitted to the display means 200 is selected and input by the user, which will be described in detail later.

Again, if we explain this in terms of a ‘window’, the sensor installed in the door frame detects whether the window that can be opened or closed is open or not. In this way, the application example of the door shape, which will be described later, can also be applied to the window shape.

As another example, when user A who wants an augmented reality content provision service opens the first door to access the augmented reality content provision service and receive a video call function with user B located at a distance, The sensor detects the opening of the first door and transmits a detection signal to the content control means 300. When the detection signal is received, the content control means 300 selects content providing a video call function from pre-stored augmented reality content and transmits it to the display means 200, and the display means 200 selects content providing a video call function. It will be printed. At this time, the content control means 300 is separately provided in the connection means 100 where user B is located in order to inform user B, who is connected through the augmented reality content providing service, that user A wants a video call function. A control signal is generated to operate the chime bell. Afterwards, when user B recognizes the chime bell and opens the first door, the sensor detects the opening of the first door and transmits a detection signal to the content control means 300, and the content control means 300 transmits content providing a video call function with user A to the display means 200.

At this time, as shown in FIG. 2, the first door leaf and the second door leaf have the same height in the y-axis direction with respect to the door frame, and have different lengths in the x-axis direction with respect to the door frame. Additionally, it is preferable that the length of the first door panel in the x-axis direction is longer than the length of the second door panel in the x-axis direction. That is, the first door that can be opened is formed to be wider than the second door that cannot be opened, and when the user opens the first door to access the augmented reality content providing service, the narrower second door is fixed to the door frame. Since it is closed, it is preferably configured to block a portion of the user's view looking at the display means 200. Through this, users can improve the sense of space and immersion of augmented reality content for other users or other locations beyond the actual door.

In addition, in order to further improve the sense of space and immersion of augmented reality content provided with part of the view obscured, as shown in a) of Figure 2, it is preferable that each door panel includes a predetermined number of transparent windows, and the total length ( The number of transparent windows, the height and width of transparent windows, etc. can be controlled and included based on the height in the y-axis direction, and these control parameters are used to maximize the sense of space and immersion of augmented reality content provided with the view partially obscured. Corresponds to the value. Therefore, as described above, it is controlled in consideration of the size of the display unit 200 and the connection unit 100, the user's location, etc., and is not limited thereto.

The content control means 300 is an 'image processing device', and as described above, uses user-related information input together with the input signal of the connection means 100, and augments information previously stored in accordance with the information. Real content is controlled and transmitted to the display means (200). At this time, the input signal includes the detection signal and desired content input information input from the user (connected content with other users, real-time viewing content for a specific location, virtual space access content, etc.).

The content control means 300 takes into account the user-related information transmitted from the access means 100, corrects the augmented reality content, in other words, performs image processing of the augmented reality content, and displays the display means 200. ) is desirable to transmit.

For this purpose, the connection means 100 preferably acquires the user's key information through a sensor that detects the opening of the first door, and acquires key information in addition to the sensor that detects the opening of the first door. It is desirable to further include a sensor (for example, an infrared sensor) on the door frame.

The access means 100 transmits key sensing information to the content control means 300, and the content control means 300 uses the key sensing information to predict and calculate the user's key information.

The content control means 300 preferably controls the camera provided in the access means 100 using the predicted key information of the user, in other words, controls the state of the main camera for capturing the user. do.

When the connection means 100 is equipped with two or more cameras that are on the same line but have different installation heights, the content control means 300 sets the main camera for capturing the user using the predicted key information of the user. It is desirable to do so.

In detail, it is preferable that the content control means 300 select a camera installed close to the height of the user's viewpoint based on the user's key information and set it as the main camera for photographing the user.

In addition, when the connection means 100 is equipped with one camera, the content control means 300 preferably controls the installation height of the camera for user photography using the predicted height information of the user. .

In detail, the content control means 300 preferably sets the fixed height of the camera to match the height of the user's viewpoint based on the user's height information and controls the camera to be installed. Of course, in this case, it is natural that the connection means 100 is equipped with a motor, a transfer means, etc., which are operated by a control signal from the content control means 300 and control the installation height of the camera.

At this time, as shown in b) of FIG. 2, the connection means 100 is located on one side (side) of the door frame, and is a first input in the form of a button through which an input signal manipulated by the user is input. It is desirable to have more means.

It is desirable for the user to input the desired type and form of augmented reality content through manipulation of the first input means.

For example, content that provides real-time images of a location (landscape) different from the current location, content that is provided simultaneously with other users who are receiving augmented reality content provision services in a location different from the current location, The user inputs the type and form of augmented reality content desired, such as content that provides a video call function with another user located at a distance, through the first input means, and the connection means 100 receives the input and the content control means. It is preferable to send it to (300).

At this time, when content that provides a video call function with another user located at a distance is input through manipulation of the first input means, in other words, when content that does not require surrounding scenery is selected, the content control means ( 300) can activate the user's background selection.

To this end, the connection means 100 is further provided with a second input means in the form of a button located on one side of the door frame and on the front side through which an input signal manipulated by the user is input. The second input means is When a specific type of augmented reality content preset is selected by manipulating the first input means, the content control means 300 utilizes the input signal from the second input means as a valid input signal.

Through this, the user can be provided with content that provides a video call function while selecting a desired background rather than the background where the user is currently located.

Of course, it is desirable for the background of the user who input the input signal to be changed, but in some cases, the backgrounds of each other or the backgrounds of two or more users may be changed, but this is not limited.

At this time, the content control means 300 preferably predicts the height of the user's viewpoint using the predicted height information of the user and corrects the angle of view of the augmented reality content based on the height of the predicted viewpoint.

That is, when one user inputs the desired augmented reality content that he/she wishes to receive through the augmented reality content provision service, the content control means 300 uses the key information of the corresponding user to determine the height of the user's viewpoint (the height of the eye). position), and correct the augmented reality content so that the angle of view is achieved at a height that matches the predicted viewpoint height among the entire screen of the generated augmented reality content, and display the augmented reality content to the display means 200 where the corresponding user is located. It is desirable to provide

To be more specific, augmented reality content is usually created using high-resolution/wide-angle-of-view photography means, so the entire screen cannot be seen with a human's angle of view. If augmented reality content is provided without taking this into account, the sense of immersion/realism is bound to be low because the content is beyond the human perspective. In addition, when looking at the sea that actually contains the horizon in the human field of vision, it is natural that the height of the horizon visible when standing and the horizon visible when sitting, and the ratio of the sea, sky, and land, are different, but conventional augmented reality content Due to the provision of content at a fixed time (filming time) without taking this into account, if you are provided with ocean content that includes the horizon, it is natural that when you stand and then sit down to watch, the sense of immersion is lowered because the ocean feels higher. do.

In order to solve this problem, the content control means 300 corrects the angle of view provided according to the height of the user's viewpoint, even if it is the same content, as shown in Figure 4 a) and Figure 4 b). It can improve users’ sense of immersion in content.

The above-described problem becomes more noticeable when two or more users are simultaneously provided with augmented reality content that is linked to each other, such as the metaverse.

In other words, in the process of expressing oneself as a character in a virtual space, if content is provided to a 180 cm tall character and a 155 cm tall character without considering the difference in viewpoint between them, the 180 cm tall character and the 155 cm tall character will be Even though they are facing each other, the 180 cm character is staring at the space behind the 155 cm character, and the 155 cm character is also staring at the neck or chest of the 180 cm character, which not only lowers the sense of immersion, but also destroys the perspective of the surroundings. There is a problem.

To solve this problem, when at least two users wish to receive the same augmented reality content through the augmented reality content providing service, the content control means 300 uses the key information of each user to It is desirable to predict the viewpoint height of and symmetrically correct the angle of view of each augmented reality content so that they face each other based on the predicted viewpoint height of each user.

That is, as shown in FIG. 5, the content control means 300 controls the angle of view of the camera located on the side of the relatively short user so that the relatively tall user is looking down at the relatively short user. Then, real-time video content is transmitted. Conversely, after controlling the angle of view of the camera located on the side of the relatively tall user so that the relatively short user is looking up at the relatively tall user, real-time video content is transmitted. It is desirable to do so.

Depending on the control of the camera's angle of view, the initially set installation height of the camera or the settings of the main camera may be changed and controlled. Of course, it is desirable that this be temporarily controlled for change while the corresponding content is provided.

In addition, the connection means 100 is preferably provided on one side with a third input means located on the front side through which an input signal manipulated by the user is input.

When at least two users wish to receive augmented reality content that allows character selection through the augmented reality content providing service through the content control means 300, input character selection according to the input signal of the third input means. You will receive it.

The content control means 300 selects augmented reality content capable of character selection according to an input signal from the first input means, and then, when a character is selected according to an input signal from the third input means, the corresponding user Using the key information, the character object of the augmented reality content is added by matching the viewpoint height of the linked character based on the predicted user's viewpoint height.

In addition, after selecting augmented reality content that allows character selection according to the input signal of the first input means, even if the character is not selected according to the input signal of the third input means, the corresponding user's key information is used. Therefore, it is desirable to predict the height of the user's viewpoint and symmetrically correct the angle of view of the augmented reality content so that it faces the linked character based on the predicted height of the user's viewpoint.

Specifically, in the case of content such as Metaverse that allows direct intervention in augmented reality content by selecting a character that represents the user, in the case of a user who selects a character, a linked character is created using the corresponding user's key information. The height of the viewpoint is matched. Of course, in some cases, when the user inputs arbitrary key information, the height of the viewpoint of the linked character is matched using the entered key information.

Even though a specific user selects content that allows direct intervention in the augmented reality content by selecting a character, if the character is not selected, the augmented reality appears as it is currently captured through the camera provided in the connection means 100. It is desirable that it be created as an object in the content. At this time, when facing a linked character in augmented reality content, it is desirable to symmetrically correct the angle of view of the linked character based on the height of the user's viewpoint.

That is, as described above, the angle of view of the camera located on the side of the relatively short user is controlled so that the relatively tall user is looking down at the relatively short user, then real-time video content is transmitted, and vice versa. It is desirable to control the angle of view of the camera located on the side of the relatively tall user so that the relatively short user is looking up at the relatively tall user, and then transmit real-time video content.

As described above, the present invention has been described with reference to specific details such as specific components and drawings of limited embodiments, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above-mentioned embodiment. No, those skilled in the art can make various modifications and variations from this description.
