Application and Optimization of Multimodal Information Communication in Cultural and Creative Products in the New Media Era

As one of the most important parts of today's cultural industry products, the design and presentation form of cultural and creative products have been optimized with the development of new media technology. Based on the multimodal theory, the study constructs a system of cultural and creative products using graph neural networks, attention mechanisms, knowledge maps, and other cultural and creative product design methods. The cultural representation evaluation system of cultural and creative products is constructed using the hierarchical analysis method, and the cultural and creative products designed by the model of this paper are evaluated. Analyze the color of cultural and creative products to examine the performance of this paper's model on color. By analyzing the user experience score of cultural and creative products, the design effect of this paper's model is explored. In the evaluation index system of cultural representation of cultural and creative products, the largest proportion of the weight of the criterion layer is the external level (54.68%), and the evaluation index with the largest comprehensive weight is the pattern (27.08%). The cultural and creative products designed by the model of this paper have the largest weight proportion of the value to be modified in pattern and material, which are 36.63% and 24.15%, respectively. The mean value of each of the chromaticity analyses is less than 2, and the mean value of the total color difference is less than 3, indicating that the color performance of the cultural and creative products designed by the model of this paper is excellent. The overall scores of the four types of cultural and creative products designed by the model of this paper are between 3.92 and 4.04 in terms of user experience, and the user experience is better. © 2024 Qiyi Deng et al., published by Sciendo.
