The user's interest in each finished product is calculated through electrooculogram signal data, and the user's ideal product is screened out more accurately, which is helpful for personalized design and recommendation, and improves user satisfaction. A mapping relationship between audience parameters and the ideal first finished product is constructed, and the ideal first finished product is obtained according to the current audience parameters. Cultural and creative product design is performed accordingly, which can realize personalized customization of cultural and creative products and meet the needs of different users. The combination of VR technology and cultural and creative products has given new vitality to the design and development of cultural and creative products. Through the combination with different directions such as culture, art, creativity, and media, many different subcategories are generated, thereby enhancing the core competitiveness of cultural and creative products.

[0020] Obtain the name of the cultural and creative product, retrieve the sales database, input the name of the cultural and creative product into the sales database, and match the historical sales data corresponding to the name of the cultural and creative product; Sorting the historical sales data in descending order, setting the first value as a segmentation threshold, filtering the sorted historical sales data according to the segmentation threshold to obtain the historical sales data to be analyzed, wherein the segmentation threshold is obtained through historical experience and is used to segment the historical sales data, retaining the historical sales data that meets the conditions, and deleting the historical sales data that does not meet the conditions; Obtain the name of the cultural and creative product corresponding to the historical sales data to be analyzed, and match the corresponding appearance parameters according to the cultural and creative product name; The appearance parameters include shape, size, color, texture, decorative pattern, glossiness and transparency.

[0021] The method for screening the historical sales data to be analyzed includes: Obtaining the historical sales data after descending order and the first value, comparing the historical sales data after descending order with the first value, and when the historical sales data after descending order is greater than or equal to the first value, retaining the historical sales data after descending order, otherwise, deleting the historical sales data after descending order; The retained historical sales data in descending order is set as the historical sales data to be analyzed.

[0022] The matching method of the appearance parameters includes: The name of the cultural and creative product of the historical sales data to be analyzed is obtained, a product database is retrieved, the name of the cultural and creative product is input into the product database, and the appearance parameters corresponding to the name of the cultural and creative product are matched.

[0023] In specific implementation, accurate market analysis is performed by obtaining the names of cultural and creative products and corresponding historical sales data. This method helps to identify which products perform well in the market, thereby providing data support for the design and production of future cultural and creative products. The data to be analyzed is screened out based on historical sales data, and the corresponding appearance parameters (such as shape, size, color, texture, decorative pattern, glossiness and transparency) are matched to optimize product design. This data-driven design method can ensure that new products are more in line with market demand and consumer preferences. By setting segmentation thresholds to screen historical sales data, qualified data is retained, and unqualified data is deleted to improve sales efficiency. This method helps to concentrate resources to promote products with potential, thereby improving overall sales performance.

[0024] The method for setting the reorganization conditions includes: Obtain the appearance parameters of any historical sales data to be analyzed, namely, shape, size, color, texture, decorative pattern, glossiness and transparency, and number the appearance parameters. The appearance parameter number is Xij, where i is a natural number and j is a natural number, and j is distributed from 1 to 7. Xij represents the jth appearance parameter corresponding to the i-th historical sales data to be analyzed in descending order. Traverse each historical sales data to be analyzed and number each historical sales data to be analyzed. The reorganization conditions are set according to the numbered appearance parameters, and the reorganization conditions include: Any two values ​​of j are not the same and the values ​​of i are not completely the same, and there are 7 appearance parameter numbers in total, and the non-completeness means that at most 6 values ​​of i are the same.

The exhibition hall lighting data and exhibition hall music data are obtained through historical data.

[0026] In specific implementation, by numbering the appearance parameters and setting the reorganization conditions, a variety of cultural and creative product designs are generated. This method helps to create products with unique appearance characteristics to meet the personalized needs of different consumers. The reorganization conditions ensure the diversity of appearance parameters and the uniqueness of the combination, avoiding the duplication of product design. This helps to optimize the product portfolio and enhance the market competitiveness of products. Through the systematic numbering and reorganization condition setting, designers can design products and adjust parameters more quickly. This method improves design efficiency and shortens the product development cycle.

When the test result is dizziness, the VR scene parameters are adjusted, including reducing the scene brightness and reducing the scene switching speed, until the feedback test result is no dizziness, then the scene parameters are stopped. This method helps to reduce the occurrence of VR motion sickness and improve the user's comfort. The application of VR technology greatly enhances the interactivity of the exhibition hall. Users interact through VR devices. This highly realistic three-dimensional scene and interactivity bring users an unprecedented immersive experience.
