The full-body interaction installation is based on a wide floor projection of 6 meters in diameter, projected by two Full HD projectors (with a final resolution of 1920×1920 pixels). The system presents a virtual environment where users explore a magical world covered by a dense layer of fog. The shape of the projection is circular, thus preventing isolation of children in corners and creating a natural flow towards the middle of the virtual environment. This play area was designed to maintain user engagement with the system and prevent users from adopting passive behaviors.
Users’ tracking is based on a tracking system developed by the research group which track the two colorful butterfly nets using four HD Ready colour cameras.
