Social interaction supports are one of the fundamental factors to realize a successful inclusion in education for children with special needs, including those with Neurodevelopmental disorders. In order to develop their social interaction skills, we propose an interactive school gymnasium, called FUTUREGYM, with a large-scale interactive floor projection system. We installed high performance projectors and tracking cameras mounted on the ceiling of the gymnasium of a special needs school, providing interactive visual aids for students. We designed group activities to provoke voluntary wayfinding behavior and their social interaction:
1) A group run, called Circle-Run, promotes their cooperative running behaviors;
2) A group game, called Constellation Game, leads to the positive behaviors and stimulates helping behaviors;
3) A group stage, called Otsuka Olympic, helps enhancing motivation in sports events.
We have confirmed the feasibility of the proposed environment throughout field studies with children with special needs.
