When the display screen is replaced or the parameters are adjusted, users may experience visual disorientation due to changes in angle, thereby reducing the continuity and comfort of viewing.

[0059] The following description and accompanying drawings fully illustrate specific embodiments of this application to enable those skilled in the art to practice them.

[0060] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0061] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of systems and methods consistent with some aspects of this application as detailed in the appended claims.

[0062] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0063] This application provides a preset multi-screen splicing model, which is used to calculate the target viewing distance required for the user to obtain the best visual effect. Therefore, when the display screen is replaced or the parameters are adjusted, the target viewing distance required for the best visual effect can be recalculated through this model as the basic parameter for content adjustment, so that the user will not experience visual misalignment due to changes in angle, thereby improving the continuity and comfort of viewing. The following is a detailed description using exemplary embodiments.

[0064] Please see Figure 1 , Figure 1 This is a schematic diagram of the system structure of an interactive 3D display system provided in an embodiment of this application. The system includes a server, a display module, and an interactive device. The display module is composed of multiple displays, and the angle between any two displays is a preset angle. The server is communicatively connected to both the display module and the interactive device. The interactive device is used to send an interaction request to the server based on the user's gestures. The server receives the interaction request sent by the interactive device and adjusts the content displayed on the display module based on the interaction request and a preset multi-screen splicing model. The preset multi-screen splicing model is used to calculate the target viewing distance required by the user to obtain the best visual effect.

[0065] User gestures are the way users communicate with the display module through hand movements. These gestures can be simple (such as waving or pointing) or complex (such as specific hand shapes or movement sequences) and are recognized by the system as interaction commands. Interaction requests are requests generated by user gestures; these requests are recognized by the system and converted into specific operation commands to trigger or control functions in the display system. Interaction devices are devices used to capture user gestures, such as LeapMotion Controllers or other types of gesture recognition sensors. They can detect and interpret user hand movements and convert these movements into electrical signals sent to the server. Adjusting the displayed content involves the system adjusting the content on the display module in real time based on the user's interaction requests and the multi-screen splicing model to adapt to the user's viewing needs and provide the best visual experience. The target viewing distance refers to the specific distance the user should maintain from the display screen to obtain the best visual effect. This distance is calculated by the multi-screen splicing model to ensure that the user can see a complete, visually undistorted 3D image at this distance.

[0066] In this application, on the one hand, a preset multi-screen splicing model is provided. This model is used to calculate the target viewing distance required for the user to obtain the best visual effect. Therefore, when the display screen is replaced or the parameters are adjusted, the target viewing distance required for the best visual effect can be recalculated through this model as the basic parameter for content adjustment, so that the user will not experience visual misalignment due to changes in angle, thus improving the continuity and comfort of viewing. On the other hand, this application adapts to the user's viewing space and interaction space through gesture interaction technology. Compared with traditional interaction methods such as mouse, keyboard, and touch screen, gesture interaction provides a more natural and intuitive interactive experience, with greater flexibility and a wider range of interaction.

[0067] The interaction request carries the user's spatial location information.

[0068] In some embodiments of this application, the specific process of adjusting the content displayed on the display module based on the interaction request and the preset multi-screen splicing model includes: calculating the real-time distance of the user relative to the display module according to the user's spatial location information; obtaining the screen parameters of the display module; calculating the shortest observation distance according to the screen parameters and the preset multi-screen splicing model; and adjusting the content displayed on the display module based on the real-time distance and the shortest observation distance.

[0069] The user's spatial location information refers to data about the user's specific location in three-dimensional space obtained by the system through the interactive device. Real-time distance is calculated by the system based on the user's spatial location information, determining the current distance between the user and the display module. This distance is updated in real time to reflect the user's movement. The display module's screen parameters include technical specifications such as screen size, resolution, viewing angle, and brightness. These parameters directly affect the display effect and user experience.

[0070] In this embodiment, the system ensures an optimal viewing experience for users in various positions. Real-time distance monitoring allows the system to accurately perceive changes in the user's position, while the calculation of the shortest viewing distance provides clear viewing guidance. By combining screen parameters and a multi-screen splicing model, the system can intelligently adjust image content, adapting to the user's real-time position whether zooming in, zooming out, or changing the viewing angle. This method significantly improves the flexibility and adaptability of the interactive 3D display system, optimizes the user's viewing experience, reduces visual discomfort caused by positional changes, and makes users more comfortable and immersive when enjoying 3D content.

[0071] The screen parameters include the screen width, maximum outward imaging angle, and the angle between screens. There are three screens.

[0072] In some embodiments of this application, the specific process of calculating the shortest observation distance based on screen parameters and a preset multi-screen splicing model includes: inputting the screen width, maximum outward imaging angle, and inter-screen angle of the display into the preset multi-screen splicing model; outputting the shortest observation distance corresponding to the screen parameters; wherein, the calculation formula included in the preset multi-screen splicing model is:

[0073]

[0074] Among them, L t,min For the shortest observation distance, L s,min The minimum distance required for a user to observe a stereoscopic effect on a single screen is given by Θ, where Θ is the maximum outward imaging angle and Φ is the angle between screens. The calculation process from the multi-screen imaging space to the user's observation space is as follows: Figure 2 As shown, the two vertically arranged solid lines represent the display screen, and the arc represents the single-screen viewing space.

[0075] In some embodiments of this application, the specific process of adjusting the content displayed on the display module based on the real-time distance and the shortest observation distance includes: comparing the size between the real-time distance and the shortest observation distance; when the real-time distance is less than or equal to the shortest observation distance, controlling the imaging space of the content displayed on the display module to remain unchanged; or, when the real-time distance is greater than the shortest observation distance, controlling the imaging space of the content displayed on the display module to change based on the user's gesture.

[0076] Specifically, the server's configuration parameters include a CPU of Intel 12th generation i7-12700, a GPU of RTX 4080, 32GB of memory, multiple displays including three X-real holographic displays, and an interactive device using a Leap Motion Controller to achieve gesture interaction. The content displayed on the display module is three-dimensional, which can be static or dynamic.

[0077] Specifically, the holographic display screen measures 12 cm x 16 cm, with an angle of 26 degrees between adjacent holographic displays. Static or dynamic content is implemented using a mainstream game engine, namely Unity3D.

[0078] In some embodiments of this application, the specific process of calculating the real-time distance of the user relative to the display module based on the user's spatial location information includes: converting the user's spatial location information from the local coordinate system to the spatial coordinate system under the display module to obtain the converted coordinate information; calculating the Euclidean distance between the converted coordinate information and the center point of the display module; and using the Euclidean distance as the real-time distance of the user relative to the display module.

[0079] In some embodiments of this application, the specific process of sending an interaction request to the server based on the user's gesture includes: real-time acquisition of the user's gesture image; analysis of the gesture image to obtain a gesture identifier representing the user's gesture information; determination of the user's spatial position in the local coordinate system to obtain the user's spatial position information; construction of an interaction request based on the gesture identifier and the user's spatial position information; and sending the interaction request to the server.

[0080] Gesture images refer to visual images of a user's hand movements captured by a camera or sensor. Gesture identifiers are identifying information representing specific gestures obtained by analyzing gesture images; this information characterizes the user's hand gestures. The local coordinate system is a reference coordinate system defined in the interactive system to determine the user's or object's position in space. Spatial location information refers to the user's specific location data determined in the local coordinate system; this data can be two-dimensional or three-dimensional coordinate points.

[0081] In this embodiment, by real-time acquisition and intelligent analysis of user gesture images, the system can accurately capture and recognize user gestures, converting them into specific gesture identifiers. Combined with the user's spatial location information in the local coordinate system, the system can construct accurate interaction requests that reflect the user's intent and location status. By sending these interaction requests to the server, this application achieves an efficient and intuitive interaction method, enabling users to communicate and control the system through natural gestures. This interaction method not only improves the naturalness and intuitiveness of the user experience but also enhances the system's response speed and the accuracy of the interaction.

[0085] S103, Obtain the screen parameters of the display module;

[0086] S104, calculates the shortest viewing distance based on screen parameters and a preset multi-screen splicing model;

[0087] The screen parameters include the screen width, maximum outward imaging angle, and the angle between screens. There are three screens.

[0088] In this embodiment, calculating the shortest viewing distance based on screen parameters and a preset multi-screen splicing model specifically includes: inputting the screen width, maximum outward imaging angle, and inter-screen angle of the display into the preset multi-screen splicing model; and outputting the shortest viewing distance; wherein the preset multi-screen splicing model includes the following calculation formula:

[0089]

[0090] Among them, L t,min For the shortest observation distance, L s,min Θ is the minimum distance required for a user to observe a stereoscopic effect on a single screen, Θ is the maximum outward imaging angle, and Φ is the angle between screens.

[0091] S105 adjusts the content displayed on the display module based on the real-time distance and the shortest observation distance.

The scenario diagram includes a system composed of a server, an interactive device, and a display module.

This model is used to calculate the target viewing distance required for the user to obtain the best visual effect. Therefore, when the display screen is replaced or the parameters are adjusted, the target viewing distance required for the best visual effect can be recalculated through this model as the basic parameter for content adjustment, so that the user will not experience visual misalignment due to changes in angle, thus improving the continuity and comfort of viewing.
