The actual multisensory environment (MSE) is in an air conditioned converted double classroom. It is pitch black with the lights off and the door closed, although the ceiling, walls and floor have been painted white to provide a neutral three dimensional ground. Hulsegge and Verheul made important early attempts to formulate a system of values to underpin use of the MSE. Their 'snoezelen' philosophy was developed from working in a residential institution with individuals of all ages, but was more related to recreation and leisure for adults than to education for children. The 'child-led repertoire' or passive approach described a room that was comfortable, gentle, quiet and warm where emphasis was placed on positive, emotional reactions. The MSE can become a place for the congregation of children with disabilities or a place where non-disabled children visit with children with disabilities. An educational definition of the MSE must begin with the individual child.
