We investigated KANSEI difference between a child and a caregiver in room arrangement workshop. Seven pairs of parents and children volunteered to participate in a workshop held in a university in Japan. In the workshop, each child and caregiver arranged a room layout using a prepared set of furniture. We then interviewed them about the layout of the arranged room and their own room at their home. We categorized their arrangement of the furniture into "center-arrangement" and "corner-arrangement" using video-data. Results show that half of the children arranged a piece of furniture in the center of the room whereas all caregivers arranged a piece of furniture at a corner. Interview data suggested this difference reflected their KANSEI differences such as preferred activities and perspectives toward room arrangement between children and caregivers.
