Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The detailed description, which will be given below with reference to the accompanying drawings, is intended to explain exemplary embodiments of the present invention and is not intended to represent the only embodiments in which the present invention may be practiced.

In the present invention, an authoring tool interface system that allows a plurality of users to participate in a 360 degree space can be controlled. In particular, an authoring tool interface according to the size and use of a cylindrical display will be proposed. Accordingly, first, the difference between the cylindrical display and the planar display will be described.

1 to 3 are views for explaining the difference between the cylindrical display and the flat display according to an embodiment of the present invention.

The movement of an object on a flat panel display and the movement of the object on a cylindrical display may differ in terms of the continuity of the viewer's visual perception.

Referring first to FIG. 1, as shown in FIG. 1, (1) when one object moves from position 1 to position 2, i.e., 1/4 of the whole, on a flat display, and (2) on a cylindrical display. If you move from position 1 'to position 2' by a quarter (90 degrees) of the whole, you can perceive that the object has moved to the right, assuming the observer is at position A.

When the range of movement of the object is small in this way (for example, the range of less than a quarter or less than 90 degrees, etc.), the movement of the object on the flat display and the cylindrical display when viewed from the observer's point of view You may not notice any difference between the movements of objects on the screen.

However, when the movement of the object is large, that is, when the movement range of the object is large (for example, over a quarter of the whole or over 90 degrees or more), the planar display is viewed from the viewpoint of the observer. The motion of the object and the motion of the object on the cylindrical display may be perceived as different movements.

As a more specific example, if a particular object moves by at least a quarter of the whole from position 3 to position 4 on the flat panel display and on the cylindrical display the specific object is moved from position 3 'to position 4'. If you move by 1/2 (180 degrees), assuming that the viewer is in position B, the user (or observer) can visually perceive the movement of the object on the flat display seamlessly, On the cylindrical display, it is recognized that the object has moved to the opposite side, and after a certain point of time, a deviation occurs from the observer's perspective.

In addition, when the movement of the object becomes larger on the cylindrical display, it may return to the observer's visual range again. For example, if an object moves from position 4 'to position 3', the user (or observer) at position B may re-perceive the particular object that was just out of sight.

As shown in FIG. 2, unlike a flat panel display, a cylindrical display device can observe 360 degrees, and as a result, only a part of the cylindrical display can be perceived according to a viewer's position. May occur.

That is, the observer can perceive different content depending on which of the positions A, B, C and D is looking at the cylindrical display. That is, if the observer is at position A and at position B, there may be overlapping content, and the content of the area close to position D at position A is not recognized at observer's position B, and position C at position B The contents of the area close to are not recognized at the viewer's position A.

In addition, the difference between the flat panel display and the cylindrical display may also occur in the expression of depth. In the flat display, the depth can be expressed indefinitely as the expression of depth, whereas in the cylindrical display, the depth is limited only by the diameter to express the actual space.

As shown in FIG. 3, on a flat-panel display, the entire Computer Graphic (CG) output falls within the observer's field of view, whereas on a cylindrical display, the entire 360-degree field of view cannot be seen at a glance. Constraints may arise. According to a related study, only about 44% of viewers see a flat display.

Cylindrical display devices can be classified into small and large according to their size. It should be noted that the small and large classification criteria in the present invention are arbitrarily defined for the purpose of explanation, and are not limited thereto.

The small cylindrical display and the large cylindrical display described in the present invention can explain the characteristics thereof as shown in Table 1 below. As described above, the size for dividing the small and the large is for convenience of description and may be set in larger or smaller units than the following criteria.

Classification small type large size 18 inches-110 mm 77 inches location Variable (movable, rotatable) Fixed (mounting type) user Personal media / per person Public media, multi-user Content feature Control of display area of main information-Synchronize output direction according to line of sight
-360 degree rotation, direction detection
Cylinder shape incidence
Personal and emotional content Continuity of the output image
-Image output side split control
-360 degree multi-use
Visual representation and distortion correction
Overwhelming, immersive content Spatial Perception -Real time image processing by movement-According to the position between user and cylinder
Space perception
-Dimensional effect through post processing such as DOF, distortion Spatial Perception through Cylinder Shape Recognition
Depth representation in the cylinder
-Expression through applying multiple layers Authoring Tool Features Image generation and distortion correction for large curvature
-Control output result by movement
Personalized custom content features -Seamless 360 degree output
Output surface control according to user number
-Control output result according to curvature (diameter)

As shown in Table 1, it can be classified according to the size of the cylindrical display device, in the case of a small cylindrical display may be a display device having a size of about 110mm to 18 inches. For example, a cylindrical smartphone or a cylindrical electronic album may correspond to this.

In the case of a large cylindrical display device, the device may be about 77 inches or more, and may be a display device installed on a pillar of a building.

In the case of a small cylindrical display, the user can move or carry it, and the user can rotate or operate it according to the advantage of the size, while in the case of a large cylindrical display, it is installed in a building pillar or a large sculpture in one space. Can be fixed.

In the case of a small cylindrical display, personal media content can be provided and used by one or two people. Features that can be derived when two persons use a small cylindrical display will be described later.

Large cylindrical displays can, depending on their size, provide public media content for many as well as individuals and output to two or more multi-users.

It is possible to display content having different characteristics between the small cylindrical display and the large cylindrical display. That is, in the case of the small cylindrical display, the display area of the main information can be controlled, and the output direction can be synchronized according to the gaze position. In addition, the 360-degree rotation and direction can be detected to further highlight the shape of the cylinder, there is a feature that can utilize personal or emotional content.

In the case of large cylindrical displays, the output results have visual continuity and can be controlled by dividing the output plane. You can also correct distortion as well as visual representation with 360-degree multi-use, and take advantage of overwhelming or immersive content.

The small cylindrical display and the large cylindrical display may have different spatial perceptual characteristics. For example, in the case of a small cylindrical display, real-time image processing may be performed according to the movement of the display, and spatial perception may be provided according to a position between a user and a cylinder. The three-dimensional effect may be implemented through post-processing such as depth of field (D DOF) and distortion correction.

In the case of a large cylindrical display, it is possible to provide spatial perception through cylinder shape recognition and to express depth in a cylinder. In addition, it is possible to express a space through a multi-layer application.

There may be different authoring tool functional features between the small cylindrical display and the large cylindrical display. In the case of a small cylindrical display, it has a large curvature, so that image generation and distortion can be corrected accordingly. In addition, it is possible to control the output result according to the movement, it is possible to implement a personalized content function.

In the case of large cylindrical displays, seamless 360-degree output is possible, and the output plane can be divided and controlled according to the number of users. Since the curvature is relatively small, the output result can be controlled according to the diameter.

In the case of a small cylindrical display, since it has a large curvature, distortion of the output image may occur. When displaying objects of the same size on small and large cylindrical displays, the image distortion that is pushed by and behind the cylinder may be large in the small size.

Therefore, there is a demand for a method that can be utilized as a content utilizing a cylindrical shape by utilizing a curved feature, rather than correcting image distortion caused by a large curvature like a plane.

In the case of a small cylindrical display, distortion may occur even when objects of different sizes are displayed. For large objects, severe distortion can be avoided by controlling the size of the output so that a single object can be properly represented throughout the display. By controlling the size of the output, there is an advantageous effect that the presentation intent is not altered and the accuracy of information transmission can be improved.

Such distortion may also occur depending on the horizontal area of the object. It can be seen that content distortion is reduced when the horizontal area is small compared to the case where the horizontal area of the object is large. Therefore, the content creation and authoring tool function may include a function of controlling the horizontal area of the object.

In the case of the small cylindrical display, it may have a variable feature depending on the position between the user and the display device. As the user may change or manipulate the position of the display device, detailed visual expression is required when the distance to the user is close, and the output result may be rotated by the user's rotation operation. In addition, when the user moves in the hand, the content may look different depending on the distance or direction.

In the case of the small cylindrical display having a size that can be manipulated by the user, the displayed output may also be perceived differently according to the change of the user's gaze direction. The main image, such as the main object, can implement a function that can be located in front of the user's gaze, and the content can be expressed according to the angle viewed from the position and the direction in which it is placed.

In addition, by expressing the result differently according to the case where the user looks at the main object from above (up) or from below (down), it is possible to express a seamless formative feature of the cylinder. When the rotation animation effect is applied to the final visual output content, the cylindrical display itself may be rotated.

In the case of the small cylindrical display according to the present invention, personal media content can be extended to two persons.

In the case of the existing small cylindrical display, although the user's viewing range (visible area) is limited to about 44% of the flat display, the content is provided in accordance with one person's view. In the present invention, based on the front of the small cylindrical display, by providing different contents on the opposite side of the 180-degree position, it is possible to provide personal media content that satisfies both.

In other words, by dividing the image into half and visualizing each within a limited output range, by providing the same or different content on the two divided sides, there is an advantageous effect that two people can meet the use experience at the same time.

Hereinafter, a tool for authoring a cylindrical display-dedicated 360-degree audiovisual content according to an embodiment of the present invention will be described.

4 to 5 show examples of cylindrical displays that can be applied in accordance with one embodiment of the present invention.

Second, procedural language should not be required from the author. Since authors are not programmers, they should not require a procedural language to produce their output. Third, the special effects function should be diverse. You need to be able to support a variety of special effects such as fade-in, fade-out, cutaway dissolve, and particles. Fourth, it should be a comprehensive authoring tool for video such as graphics, text, and animation. Fifth, as a 360-degree image, there should be a difference from the existing authoring tool of flat display-based content. Sixth, real-time programming that can confirm the authoring work in real time should be supported.

The content authoring tool according to the present invention may have various types. The hypertext-based document method, the card method, the page method, and the flowchart method can be classified, and the flowchart method can be divided into the icon method and the timeline method.

The card-based authoring tool can be distinguished from the flowchart method in that it provides interactivity using an embedded language, that is, a script language, in the authoring process.

In the case of the document method, the hypertext-based authoring tool does not include most graphic editing functions, and mainly deals with text media. It includes an indexing function and a searching function, and may be suitable for authoring content such as a book.

The page method expresses all information in units of cards, and a bundle of several cards may be defined as a stack. One card contains text and graphics and in the case of sound and video is marked as a button and can be executed when the button is pressed.

In the icon method, the flow of a program can be represented in a flowchart form using an icon. The icon method can easily understand the development process of the program, and one icon expresses media data such as pictures, sounds, and video, and the conversation function with the user can also be represented by an icon.

The timeline method is a method of arranging the execution order of each media according to the time-axis, and has an advantageous effect that the synchronization relationship between media files can be described in units of frames, compared to other methods. This can be convenient for product promotions that don't require much user input and require spectacular screen effects or audio.

That is, the menu configuration of the content authoring tool according to the present invention may provide various methods according to the author type, provide a UI that can be checked in real time, and can be easily provided so that a non-expert can also author.

Hereinafter, the UI / UX configuration of the content authoring tool according to the present invention will be described. In general, User eXperience (UX) refers to the behavior and attitude of a person and the experience of using a particular product, system or service, which includes real, experience, emotion, meaning and human-computer interaction ownership and value. Concept.

In addition, although a user interface (UI) is generally a form of design, it may mean that the user and an object interact, that is, communicate with a computer program or system. As a relay between users and content, interpreters, and guides on complex sites, it can be thought of as designing and evaluating the user's ease of use in order to make the system easier to use.

In addition, the graphical user interface (GUI) may refer to a visual graphical interface that facilitates interaction and smooth communication between the device and the user. When a system called an interface is assumed to be information that is not visible to the user, this invisible interface is converted into a graphic suitable for each device information so that the user can visually see, feel, and use the screen. It may be a method.

The content authoring tool according to the present invention may be provided in a trendy manner according to the changing times.

Recently, as the demand for content increases due to the popularization of high-performance smart devices, the need for a content authoring tool is increasing to reduce content authoring cost and authoring time.
