Application of Virtual Technology in the Renovation of Ancient architectures Based on Kano Model: The Example of Yongtai Ningyuanzhuang

As an ancient civilization with a long history, China has a rich variety of unique ancient architectures. Ancient architectures as an important form of expression to carry history and art, showing a long history and cultural achievements. With the continuous development of science and technology,the traditional process of protecting ancient architecture no longer meets the needs for the successful application of digital technology to usher in the digital era, and virtual technology, in which to showcase unique advantages, Taking Ningyuan zhuang in Yongtai, Fujian Province as the research object, we analyze the user demands through Kano model and discuss in depth the advantages of applying virtual technology in the protection of ancient architectures.Virtual technology, especially 3D modeling and simulation technology, plays a key role in the protection and transformation of ancient architectures. The significant advantages of virtual technology in ancient architecture protection highlight its potential value in efficient information processing, exhaustive monitoring and preventive protection. The application of virtual technology realizes the informatization management of cultural relics and architectures and provides a scientific basis for the comprehensive protection of ancient architectures.Ningyuan zhuang, as a typical architecture of Yongtai Zhuangzhai in Fujian during the Qing Dynasties, carries rich historical memories, cultural elements and the characteristics of the southern rural defense structure, making it the focus of the study due to its profound cultural connotation and historical value. The Kano model is based on user needs and implemented through a questionnaire, identifies key areas for improvement in Ningyuan zhuang, including maintenance, signage and cultural content, along with corresponding improvement suggestions.Following the improvement direction proposed by the conclusion of the Kano model, specific measures for the application of virtual technology in the repair and improvement of ancient architectures, including 3D modeling, virtual signage and interactive exhibits. In addition, for effective publicity and cultural promotion, the study provides specific suggestions for displaying virtual images and interactive experiences to enhance the overall level of protection and visitor experience at Ningyuan zhuang.In summary, this paper takes Ningyuan zhuang as a case study, and with the help of the Kano model, proposes suggestions for the application of virtual technology in the conservation of ancient architecture through a user-centered improvement strategy, providing an experimental approach to the conservation and cultural dissemination of ancient architecture. This interdisciplinary research model holds far-reaching significance for the modernization and intelligent development in the field of ancient architecture conservation, ensuring a sustainable future for the heritage of ancient architecture.
