The Korean term “Oneroom” refers to an apartment in which the bedroom, kitchen, and living room are not separated but integrated into one space. The players dive into the sea to discover Oneroom-Babel through the VR. Upon diving, players visit residential spaces, once occupied by the people in Oneroom-Babel, one after another. The spaces are filled with sentences written by the artist and extracted from interviews with the youth living in Oneroom. With the texts, sound, and the dreamlike virtual space captured by a LiDAR scanner, players experience the space of a “one-room apartment” in all possible ways.
