The Chinoiserie of the 17^th and 18^th centuries, which caused a cultural exchange between China and the West, is an important cultural heritage; therefore, its preservation, publicity, and dissemination are crucial. However, traditional exhibition methods fail to satisfy visitors who desire interactive experiences and considerable knowledge acquisition. In this study, a digital olfactory environment interactive system was used to enhance the user experience in an exhibition where scent served as an interactive medium. This system provides different scented environments for visitors by determining the relative locations and distance between visitors and Chinoiserie paintings to satisfy their diverse needs. A minimalist concept was implemented for the investigation during group collaboration. The user research results showed that the Chinoiserie painting digital olfactory environment interactive system (COIS) effectively garnered the attention of participants and improved their understanding of the Chinoiserie paintings. This study emphasizes the importance of digital environmental representation in exhibitions focused on cross-cultural exchange.
