When we observe or use something, its property seems to change because of the way we establish relationships with it. Inspired by the Uncertainty Principle – a physical theory published by Heisenberg in the year of 1927 – I take both people and objects as something always in an uncertain status. We cannot fully define objects, but only try to understand and live with it in a complex and constantly changing context.Three pieces of furniture are created to visualize the idea about how the relationships between people and objects could be from this viewpoint, exploring how far away people could accept the imperfect but surprising experience of the world.
