RU∆CH asks a seemingly simple question: what does it feel like to breathe with AI? At the center of this immersive audio experience lies a machine that utilizes text-to-speech models, heat sensors, and signal processing software to produce breathing sounds that change speed in response to a participant’s breath, as well as to narrate pre-written text. During the work’s premiere, participants were invited to take part in a one-on-one breathing meditation narrated by this “breathing” machine. As the machine follows the participant’s breath and the participant begins to unconsciously respond to the machine’s inhales, agency and impact become muddied. Following the meditation, each participant took part in an intimate conversation with the artist, exploring the complicated thoughts, emotions, and sensations that emerged during the encounter. Through its unique combination of artistic creation, experimental research, and relational aesthetics, RU∆CH invites participants into the sometimes-terrifying, sometimes-fascinating entanglements that blossom through machinic breath.
