[0080] The present invention proposes an immersive digital media interactive display system, which includes a motion capture module, a data transmission module, a main control module, a data processing module, an interactive engine module, a feedback module, a display module and a synchronization module. First, the motion capture module obtains the audience's motion and position data in real time through a high-precision motion capture device, and transmits these data to the main control module through the data transmission module. The data transmission module uses an efficient data transmission protocol to ensure that the motion data can be transmitted to the main control module in a timely and accurate manner for subsequent processing.

[0081] Under the control of the main control module, the data processing module uses the parallel computing power of the GPU to process the received action data in real time. This step involves complex calculations and analysis. By optimizing algorithms and models, the audience's action features can be quickly and accurately extracted. Next, the interactive engine module associates the parsed action data with the display content. The interactive engine module is developed using high-performance game engines such as Unity3D or UnrealEngine to achieve a high degree of interaction between the audience's actions and the display content, so that the display content can change dynamically according to the audience's actions.

[0082] The feedback module adjusts the display content in real time based on the processed action data. For example, different video content can be played, image display effects can be changed, or specific sound effects can be triggered based on the audience's actions to enhance the interactive experience. In this way, the audience can interact with the display content in a natural way and experience a more vivid and personalized display effect. All these adjustments and interactions are carried out under the unified coordination of the main control module to ensure the stability and reliability of the system.

[0083] In order to ensure the synchronization of content playback and interactive effects between multiple display devices, the synchronization module adopts distributed computing and network synchronization technology. These technologies can ensure that all display devices can display the corresponding content in real time and synchronously no matter where the audience interacts. The ultra-high-resolution LED display screen is used as an output device to provide a clear and smooth visual experience, further enhancing the sense of immersion.

Through a series of experimental data, it was found that the motion capture module of the present invention can achieve sub-millimeter accuracy of up to 0.2 mm. In comparison, the accuracy of the prior art is usually between 2-5 mm. For example, in the experiment of testing the audience's arm swinging, the motion capture module of the present invention can accurately capture the angle and trajectory of the arm swing, with an error range of only ±0.1 degrees, while the error range of the prior art reached ±2 degrees. This improvement in accuracy enables the system to more accurately capture the audience's movements and position changes, providing more accurate data support for subsequent interactive displays.

[0246] 2. Great improvement in data transmission speed and stability

[0247] During actual use, the data transmission module of the present invention was rigorously tested. The test results show that the average delay time of data transmission has been reduced to less than 5 milliseconds, which is significantly improved compared to the average delay time of the prior art (usually between 50-100 milliseconds). In addition, in the 12-hour continuous stability test, the system of the present invention did not experience any data transmission interruption or abnormality, showing extremely high stability. This fast and stable data transmission performance ensures that the system can respond to the audience's actions and instructions in real time and accurately.

[0248] 3. Significant improvement in interactive experience

[0249] In actual application, 100 volunteers were invited to participate in the interactive experience test of the present invention. The test results show that 98% of the volunteers are satisfied or very satisfied with the interactive experience of the present invention, and believe that it is more natural, smooth and rich than the existing technology.

[0253] First, the motion capture module uses high-precision motion capture equipment, which can accurately capture the audience's movements and position data in real time. During the trial, the module's capture accuracy reached sub-millimeter level, and the data acquisition delay was less than 20 milliseconds. This means that the audience's subtle movements can also be accurately captured and transmitted to the system in real time, ensuring the accuracy and immediacy of interaction.

[0254] Secondly, the data processing module uses the parallel computing power of the GPU to process the motion data in real time. Experimental data shows that the parallel computing power of the GPU has increased the data processing speed by more than 50%, and compared with the traditional CPU processing method, the processing time has been shortened by nearly half. For example, in a large-scale audience interaction experiment, the system was able to process and feedback the audience's motion data within 50 milliseconds, significantly improving the system's response speed.

[0255] The interactive engine module associates the processed action data with the display content and uses it to develop the interactive engine. During the experiment, the interactive engine module showed strong compatibility and stability, supporting various types of display content and interactive modes, and improving the applicability and scalability of the system. In a display test with complex content, the module achieved real-time association within 0.1 seconds, ensuring instant feedback for each action of the audience.

[0256] The feedback module adjusts the display content in real time according to the audience's actions, enhancing the immersiveness of the interactive experience. Experimental data shows that the system can adjust the display content within 100 milliseconds, ensuring that every action of the audience can be quickly reflected in the display. In actual application, this real-time feedback greatly enhances the audience's immersive experience and interactive satisfaction.

[0257] The display module and synchronization module ensure the synchronization of content playback and interactive effects between multiple display devices. In the multi-device interactive display test, the system achieved millisecond-level synchronization, and the content display and interactive effects between devices were completely consistent, avoiding delays and asynchrony problems. Test data showed that in the synchronization test involving more than 10 display devices, the system synchronization error did not exceed 5 milliseconds, which was significantly better than the performance of existing technologies.
