「第四面牆」指涉影像作品中，藝術家刻意打破影像內部與外在現實的某種狀態，同時也回應在觀看場域中，錄像作品於空間中所投映影像的那道牆面。他製作一個虛構的空間影像，將此影像疊合至現實中的那道牆面，試圖讓影像從現實中延展開來，並伴隨著光源去探索影像與現實的邊界和距離。
“The fourth wall” refers to a state in video works where the artist deliberately breaks the boundary between the internal narrative of the video and the external reality, while also referencing the wall onto which video works are projected in the viewing space. He creates a fictitious spatial image, superimposing this image onto the real wall, attempting to extend the image from reality, and, accompanied by the light source, explores the boundaries and distance between the image and reality.
