With the arrival of the digital era and the national promotion of non-heritage culture, traditional handicraft techniques are gradually becoming known to the public, and the dyeing and weaving crafts of the Tang Dynasty are famous for their unique technical standard and artistic value. However, due to the complexity and scarcity of the craft, there are certain difficulties in the traditional way of learning and preservation, and the development of immersive virtual reality technology provides an opportunity for the public to recognize and understand the Tang Dynasty dyeing and weaving craft. The greatest academic contribution of this paper is to reproduce and protect the traditional history and culture of China, to provide innovative interaction design concepts and to promote the application of virtual reality technology in the field of cultural heritage. First of all, through the methods of literature review and field study, this paper conducts an in-depth research on the dyeing and weaving craft of the Tang Dynasty, including its historical background, technical characteristics and artistic value, which is of great significance for the protection and education of history and culture. Through immersive virtual reality technology, the details and processes of Tang Dynasty dyeing and weaving craft can be reproduced. Through clear visual effects and dynamic interactive experience, users can feel the unique charm of Tang Dynasty dyeing and weaving craft immersively. This immersive experience can better convey the artistic value and aesthetic emotion in history and culture to users, and inspire their interest in traditional culture and awareness of protection. In addition, immersive virtual reality interaction design can also provide a new way for the promotion and dissemination of Tang Dynasty dyeing and weaving craft. Virtual reality technology can present the Tang Dynasty dyeing and weaving craft globally, so that more people can understand and appreciate the uniqueness of our traditional culture. Through channels such as the Internet and mobile terminals, users can participate in the immersive virtual reality experience anytime, anywhere, so that the Tang Dynasty dyeing and weaving craft can enter thousands of households, and make positive contributions to the protection and education of China's history and culture. Secondly, this study proposes a new interaction design concept through in-depth exploration of immersive virtual reality technology and interaction design. This concept emphasizes the user's subjective experience and emotional perception in the virtual environment, thus providing a new way to enhance the user's sense of participation and immersion. The concept focuses on the interaction and empathy between the user and the virtual environment, and enhances the user's understanding and perception of history and culture by creating empathy and emotional resonance. First, designers can create an immersive experience through multi-sensory interaction design. Using virtual reality technology, it is possible to simulate the craft scenes, environmental sounds, and even smells and tactile sensations of the Tang Dynasty, allowing users to immerse themselves in the real atmosphere of Tang Dynasty dyeing and weaving craftsmanship. Through tactile feedback and stereo sound effects, users can personally experience the texture and sound of the dyeing and weaving process, enhancing the subjective sense of participation and experience. Secondly, designers can try emotion-oriented design to guide users to deeper experience. In the design process, some emotional elements can be incorporated, such as cultural background music and emotionally-intended storylines, to create an emotional connection that makes it easier for users to empathize. Through well-designed plots and characters, create an experience with emotional tension and guidance, triggering users to think about the historical and cultural background and emotional resonance. Third, designers can use social interaction design to promote communication and sharing between users and others. Through virtual reality interactive design, it can provide users with the opportunity to communicate with other users and jointly explore and experience the Tang Dynasty dyeing and weaving process. Designers can introduce social interaction elements, such as virtual communities and online cooperation modes, to enable users to communicate and share with other users, and to experience and pass on this historical and cultural heritage together. In conclusion, in the study of immersive virtual reality interaction design for Tang Dynasty dyeing and weaving craft, innovative interaction concepts that emphasize users' subjective experience and emotional perception in virtual environments can be realized through multi-sensory interaction, emotion-oriented design, and social interaction design. Finally, this research is conducive to promoting the application of virtual reality technology in the field of cultural heritage, and its research results not only help to enrich the application field of virtual reality technology, further deepen the understanding of Tang Dynasty dyeing and textile technology and the perfection of simulation technology, but also promote the development of virtual reality technology in the field of cultural heritage. At the same time, virtual reality technology can realize large-scale user interaction and sharing, through the Internet and social media and other channels, so that more people can participate in the Tang Dynasty dyeing and weaving craft experience and learning, and can promote cross-border cooperation and cultural exchanges, and promote the interaction and sharing between different regions and cultures. In conclusion, the study of immersive virtual reality interaction design for Tang Dynasty dyeing and weaving crafts can promote the application of virtual reality technology in the field of cultural inheritance, realize the innovative protection and inheritance of traditional crafts by providing immersive experience, enriching the inheritance of traditional culture, promoting the interactive participation and learning experience of users, and promoting the popularization and sharing of cultural inheritance, and at the same time encouraging more people to use this technology to study and spread our traditional history and culture.
