This artistic research explores the use of surveillance elements in interactive art installations and the impact of participatory art on audience perception and experience. Through the development of interactive art installations that incorporate various forms of surveillance technology, including cameras, microphones, sensors, tracking devices, et cetera, this study investigates how audience participation affects the perception and experience of surveillance art, and how to raise the privacy consciousness of the audience. Drawing on theories of participatory art and surveillance, the research aims to explore how surveillance elements can be used to create engaging and immersive art installations, and how audiences respond to the presence of surveillance elements in the artwork. The research employs a range of qualitative and quantitative research methods, including literature studies and review, participant observation, and my own artistic practice, et cetera, to gather data on the artworks. The findings of the study contribute to a deeper understanding of the role of surveillance elements in my artistic practice, and provide insights into the ways in which participatory art can impact audience perception and experience, eventually supporting the idea and outcome of my final work The Lounge.
