Abstract
This study is concerned with development in the picture space by projection where I aimed at “person, picture and spatial relationship.” I found the functionality of the picture as a space material, and created the space for a person to take action by the environment. In actual fact, we have been trying to create the space in a pediatric hospital, handicapped children's school (children with a disability) and a tea party. Focusing the illusion as a feature of the image, “Phantom,” our study is also a proposal to the evolution of the functionality of picture.
