Naoto Fukasawa is a Japanese industrial designer who created the ‘Without Thought’ design philosophy. He uses entrenched human behaviour to create pieces people will instinctively be able to interact with, without the need for explanation.
His MUJI CD player is a great example of this subconscious interaction. His reasoning behind the pull cord idea was to re-enact the motion and psychology associated with a pull cord fan. He wished the user to walk into a room and pull the cord instinctively. Their mind would then prepare them for the cool breeze of air and instead they would be hit with the flow of music instead.
