Our heart keeps beating at regular intervals every day. Although the heart is inside our body, we usually are not conscious of its heartbeat.In this work, we aim to provide an experience where the participants become conscious of something unconscious within them; heartbeat.The robot arm catches information that often fall through our minds, and expresses it through a Japanese marbling technique called “Suminagashi (floating ink)” . This work encourages participants to not just focus on tangible information around us, but to reconsider the meaning of seeking for information in the unconscious world.
