Interactive Multi-Sensory Environments (iMSEs) are roomsized interactive installations equipped with digitally enriched physical materials and ambient embedded devices. These items can sense users' presence, gestures, movements, and manipulation, and react by providing gentle stimulation (e.g., light, sound, projections, blowing bubbles, tactile feel, aromas) to different senses. Most of prior research on iMSEs investigates their use for persons with disabilities (e.g., autism). Our work focuses on the use of iMSEs in primary education contexts and for mixed groups of young students, i.e., children with and without disability. The paper describes the latest version of an iMSE called Magic Room that has been installed in two local schools. We report two empirical studies devoted to understand how the Magic Room could be used in inclusive educational settings, and to explore its potential benefits.
