This research considers the audience's body as an important component of the aesthetics of immersive performance spaces, especially how the two-way interactive relationship between artistic creation and experience is shaped by bodily engagement in cross-cultural contexts. Adopting a practice-as-research methodology, the study aims to understand the audience's bodily experience, their motivations for participation, and to explore how the audience, as an 'intelligent subject', reveals contradictions in the performance space. By analyzing the intersection of performance aesthetics and cultural politics, this project aims to fill the gap of research on audience aesthetics in the field of cross-cultural performances, and to promote the theoretical and practical innovation of immersive performance spaces in multicultural contexts.
