Research on the design and image perception of cultural landscapes based on digital roaming technology

Abstract The preservation and advancement of cultural heritage continue to present significant challenges, arising from conflicting objectives, concepts, methodologies, and limited resources. Image perception not only serves as an observational tool for cultural heritage but also as a research method to uncover deeper meanings and implications. To explore the complex dynamics of cultural heritage and address the risks of its deterioration, this study employed virtual engine software (Unity 2019) to create digital landscapes for immersive exploration. An image perception evaluation framework was established through field surveys and behavioral synthesis experiments across five key areas, including ancient tree ecosystems and architectural sites. Our findings revealed that participants showed the greatest interest in the ancient tree ecological area, indicating a strong attachment to historical continuity and natural progression. Heart rate variability (HRV) analysis further demonstrated that participants experienced positive emotional responses, suggesting that well-designed cultural landscapes can enhance mental well-being and uplift mood. Additionally, participants expressed a strong willingness to discuss the ancient tree eco-region, with image perception playing a crucial role in motivating information sharing and driving conservation efforts. This study introduces an innovative model—Design Practice, Immersive Experience, and Image Perception Evaluation—which offers a new perspective for the preservation and enhancement of cultural heritage sites.
